相关技术中，暖通空调通常安装有循环泵，循环泵能够使得水在空调***内周而复始地循环，克服环路的阻力损失，满足客户供暖需求。现有的循环泵在工作过程中发生转子卡死的时候，需要将较多的部件拆卸下来才能对转子进行维护，维护很不方便。In the related art, HVAC is usually equipped with a circulation pump, which can make water circulate repeatedly in the air conditioning system, overcome the resistance loss of the loop, and meet the heating needs of customers. When the rotor of the existing circulation pump is stuck during operation, many parts need to be disassembled to maintain the rotor, which is very inconvenient.
为了解决上述的至少一个技术问题，本申请提出一种转子组件，其维护更方便。In order to solve at least one of the above technical problems, the present application proposes a rotor assembly, which is more convenient to maintain.
参照图1至图2，本申请第一方面实施例提供的一种转子组件100，转子组件100用于带动位于泵腔320的叶轮310转动，从而输送液体至循环管道内。转子组件100包括转子、屏蔽罩150和密封件160。转子包括转轴110和磁环120，磁环120固定于转轴110的外壁，转轴110与叶轮310连接，从而能够带动叶轮310转动。屏蔽罩150罩设于转子的外侧，用于将转子与定子180隔开，屏蔽罩150内充满水或是其他需要输送的液体，转子浸泡于液体中。屏蔽罩150内布置有沿轴向分布的两个轴承170，两个轴承170套接于转轴110的两端，使得转子能够在屏蔽罩150内转动。屏蔽罩150设置有与转轴110的端部对应的避让孔151，密封件160可拆卸安装于避让孔151。Referring to FIGS. 1 and 2 , a rotor assembly 100 is provided in the first embodiment of the present application. The rotor assembly 100 is used to drive the impeller 310 located in the pump chamber 320 to rotate, thereby conveying liquid into the circulation pipeline. The rotor assembly 100 includes a rotor, a shielding cover 150 and a seal 160. The rotor includes a rotating shaft 110 and a magnetic ring 120. The magnetic ring 120 is fixed to the outer wall of the rotating shaft 110. The rotating shaft 110 is connected to the impeller 310, so as to drive the impeller 310 to rotate. The shielding cover 150 is arranged on the outer side of the rotor to separate the rotor from the stator 180. The shielding cover 150 is filled with water or other liquids to be conveyed, and the rotor is immersed in the liquid. Two bearings 170 distributed along the axial direction are arranged in the shielding cover 150. The two bearings 170 are sleeved at both ends of the rotating shaft 110, so that the rotor can rotate in the shielding cover 150. The shielding cover 150 is provided with an escape hole 151 corresponding to the end of the rotating shaft 110 , and the sealing member 160 is detachably mounted on the escape hole 151 .
该转子组件100通过在屏蔽罩150对应转轴110的位置设置避让孔151，密封件160可拆卸安装于避让孔151，当转子出现卡死等状况时，可以通过将密封件160从避让孔151拆卸出来，然后通过工具伸入避让孔151内转动转轴110，从而快速解决转子卡死等问题，同时能够将泵腔320内残留的气体排出，该转子组件100在维护时不需要拆卸过多的部件，维护操作非常方便，提高了转子组件100维护的效率。The rotor assembly 100 is provided with an avoidance hole 151 at a position of the shielding cover 150 corresponding to the rotating shaft 110, and the sealing member 160 is detachably installed in the avoidance hole 151. When the rotor is stuck or other problems occur, the sealing member 160 can be removed from the avoidance hole 151, and then a tool can be inserted into the avoidance hole 151 to rotate the rotating shaft 110, thereby quickly solving the problem of rotor sticking and the like, and at the same time, the residual gas in the pump chamber 320 can be discharged. The rotor assembly 100 does not need to disassemble too many parts during maintenance, and the maintenance operation is very convenient, thereby improving the maintenance efficiency of the rotor assembly 100.
参照图1和图4，可以理解的是，为了使得密封件160能够快速安装和拆卸，同时具有较好的密封性能，在本申请的一些实施例中，密封件160为密封螺栓，密封螺栓能够螺接于避让孔151的内壁。密封螺栓的螺帽可以设置有一字槽或者十字槽，从而方便通过工具拧转密封螺栓以实现密封螺栓的安装或拆卸。密封螺栓螺接锁紧于避让孔151的内壁时，密封螺栓能够很好地封住避让孔151，从而防止屏蔽罩150内的液体从避让孔151内流出。当然，还可以在密封螺栓的螺帽下端配置胶垫，从而使得密封螺栓螺接锁紧于避让孔151的内壁时，胶垫受压变形而紧贴于密封螺栓的螺帽下端面以及屏蔽罩150的上端面，从而实现良好的密封效果。With reference to FIG. 1 and FIG. 4 , it can be understood that in order to enable the seal 160 to be quickly installed and removed and have good sealing performance, in some embodiments of the present application, the seal 160 is a sealing bolt, which can be screwed to the inner wall of the avoidance hole 151. The nut of the sealing bolt can be provided with a slot or a cross slot, so that it is convenient to screw the sealing bolt with a tool to achieve the installation or removal of the sealing bolt. When the sealing bolt is screwed and locked to the inner wall of the avoidance hole 151, the sealing bolt can well seal the avoidance hole 151, thereby preventing the liquid in the shielding cover 150 from flowing out of the avoidance hole 151. Of course, a rubber pad can also be configured at the lower end of the nut of the sealing bolt, so that when the sealing bolt is screwed and locked to the inner wall of the avoidance hole 151, the rubber pad is compressed and deformed and is tightly attached to the lower end face of the nut of the sealing bolt and the upper end face of the shielding cover 150, thereby achieving a good sealing effect.
参照图2和图3，需要说明的是，为了方便用户通过工具带动转轴110转动，在本申请的一些实施例中，转轴110设置有便于带动其转动的卡接部111，卡接部111位于转轴110朝向避让孔151的一端。当转子卡死时，用户可以先将密封件160从避让孔151上拆卸下来，然后将工具伸入避让孔151内，通过工具与转轴110的卡接部111相配合，从而带动转轴110转动，解决转子卡死的问题。由于转轴110设置有卡接部111，因此用户可以通过工具配合卡接部111，快速地带动转轴110转动，从而提高维护的效率。Referring to FIG. 2 and FIG. 3 , it should be noted that, in order to facilitate the user to drive the rotating shaft 110 to rotate by using a tool, in some embodiments of the present application, the rotating shaft 110 is provided with a clamping portion 111 that is convenient for driving it to rotate, and the clamping portion 111 is located at one end of the rotating shaft 110 facing the avoidance hole 151. When the rotor is stuck, the user can first remove the seal 160 from the avoidance hole 151, and then insert the tool into the avoidance hole 151, and through the tool and the clamping portion 111 of the rotating shaft 110, the rotating shaft 110 is driven to rotate, thereby solving the problem of the rotor being stuck. Since the rotating shaft 110 is provided with the clamping portion 111, the user can use the tool to cooperate with the clamping portion 111 to quickly drive the rotating shaft 110 to rotate, thereby improving the efficiency of maintenance.
参照图3，可以理解的是，在本申请的一些实施例中，卡接部111可以为内凹的多边形结构，例如，卡接部111可以为内六角槽结构，可以通过扳手伸入内六角槽内，然后转动扳手，从而带动转轴110转动。当然，卡接部111也可以是外凸的多边形结构，例如，卡接部111可以为六角螺帽状的结构，通过扳手套接于螺帽上，然后转动螺帽，即可带动转轴110转动。当然，卡接部111还可以是三棱柱或是方柱等形状的结构，卡接部111能够承受较大的扭矩，从而通过相应的工具配合卡接部111，便能够轻易地带动转轴110转动，从而提高转子维护的便捷性。Referring to FIG. 3 , it can be understood that in some embodiments of the present application, the clamping portion 111 can be a concave polygonal structure, for example, the clamping portion 111 can be a hexagonal inner groove structure, and a wrench can be inserted into the hexagonal inner groove, and then the wrench can be turned to drive the rotating shaft 110 to rotate. Of course, the clamping portion 111 can also be a convex polygonal structure, for example, the clamping portion 111 can be a hexagonal nut-shaped structure, and a wrench can be connected to the nut, and then the nut can be turned to drive the rotating shaft 110 to rotate. Of course, the clamping portion 111 can also be a structure in the shape of a triangular prism or a square column, and the clamping portion 111 can withstand a large torque, so that the corresponding tool can be used to cooperate with the clamping portion 111, so that the rotating shaft 110 can be easily driven to rotate, thereby improving the convenience of rotor maintenance.
参照图2，需要说明的是，为了减少装配的工序，提高转子组件100的装配效率，在本申请的一些实施例中，转子还包括包塑于转轴110的外壁的包塑件130，包塑件130为塑料材质构成。包塑件130连接于磁环120与转轴110之间，从而将磁环120固定于转轴110。制作转子时，通过注塑工艺，将磁环120和转轴110通过模具进行固定，然后将熔融的塑料注塑于磁环120与转轴110之间，从而使得磁环120和转轴110实现一体注塑成型，减少后续的装配工序，提高转子组件100的装配效率，同时使得转子的结构更为紧凑，有利于减小转子组件100的整体体积，而且能够使得转子的结构稳定性更强，避免磁环120在工作过程中容易松动。Referring to FIG. 2 , it should be noted that, in order to reduce the assembly process and improve the assembly efficiency of the rotor assembly 100, in some embodiments of the present application, the rotor further includes a plastic overmolding member 130 overmolded on the outer wall of the rotating shaft 110, and the plastic overmolding member 130 is made of plastic material. The plastic overmolding member 130 is connected between the magnetic ring 120 and the rotating shaft 110, thereby fixing the magnetic ring 120 to the rotating shaft 110. When manufacturing the rotor, the magnetic ring 120 and the rotating shaft 110 are fixed through a mold through an injection molding process, and then the molten plastic is injected between the magnetic ring 120 and the rotating shaft 110, so that the magnetic ring 120 and the rotating shaft 110 are integrally injection molded, reducing the subsequent assembly process, improving the assembly efficiency of the rotor assembly 100, and making the structure of the rotor more compact, which is conducive to reducing the overall volume of the rotor assembly 100, and can make the structural stability of the rotor stronger, and prevent the magnetic ring 120 from being easily loosened during operation.
相关技术中，传统循环泵的定子总成装配于壳体中，定子总成的中部设置有屏蔽盖，转子安装于屏蔽盖内腔，壳体与屏蔽盖之间设置有排水槽，从而避免冷凝水或水蒸气浸入甚至积压于定子导电部分。为此，在本申请的一些实施例中，定子180为包塑定子，从而使得定子180的防水性能更好，降低定子180的导电部分浸水的风险，而且无需设置排水结构，降低制造成本，同时能够进一步减少零部件的数量，提高装配的效率。In the related art, the stator assembly of the conventional circulation pump is assembled in the housing, a shielding cover is provided in the middle of the stator assembly, the rotor is installed in the inner cavity of the shielding cover, and a drainage groove is provided between the housing and the shielding cover to prevent condensed water or water vapor from infiltrating or even accumulating in the conductive part of the stator. For this reason, in some embodiments of the present application, the stator 180 is a plastic-coated stator, so that the waterproof performance of the stator 180 is better, the risk of the conductive part of the stator 180 being immersed in water is reduced, and there is no need to provide a drainage structure, which reduces the manufacturing cost, and can further reduce the number of parts and components and improve the efficiency of assembly.
需要说明的是，转子工作的时候，转轴110带动位于泵腔320的叶轮310转动，屏蔽罩150内有液体，转子浸泡于液体中，为了减少液体中的杂质在屏蔽罩150内沉降，参照图2，在本申请的一些实施例中，转轴110设置有轴向贯穿的第一通孔112，包塑件130设置有轴向贯穿的第二通孔，转轴110转动时，液体能够通过第一通孔112和第二通孔在泵腔320和屏蔽罩150的内部空间之间流动，从而可以有效减少液体中的杂质的沉降，避免出现水垢而影响转子的正常工作，有利于减少转子出现卡死的频率，提高转子工作的稳定性。当然，第二通孔可以设置有多个，多个第二通孔沿包塑件130的周向间隔设置，从而使得液体在泵腔320和屏蔽罩150的内部空间之间的流动更为顺畅，进一步减少液体中的杂质在屏蔽罩150内的沉降，有利于维持转子转动的顺畅性。It should be noted that when the rotor is working, the shaft 110 drives the impeller 310 located in the pump chamber 320 to rotate, there is liquid in the shielding cover 150, and the rotor is immersed in the liquid. In order to reduce the impurities in the liquid from settling in the shielding cover 150, referring to FIG. 2, in some embodiments of the present application, the shaft 110 is provided with a first through hole 112 that penetrates axially, and the overmolding 130 is provided with a second through hole that penetrates axially. When the shaft 110 rotates, the liquid can flow between the pump chamber 320 and the internal space of the shielding cover 150 through the first through hole 112 and the second through hole, thereby effectively reducing the sedimentation of impurities in the liquid, avoiding the occurrence of scale and affecting the normal operation of the rotor, and helping to reduce the frequency of the rotor being stuck and improve the stability of the rotor. Of course, a plurality of second through holes can be provided, and the plurality of second through holes are arranged at intervals along the circumference of the overmolding 130, so that the liquid flows more smoothly between the pump chamber 320 and the internal space of the shielding cover 150, further reducing the sedimentation of impurities in the liquid in the shielding cover 150, which is conducive to maintaining the smoothness of the rotor rotation.
可以理解的是，转子工作的时候，其转速比较大，因此转动惯量比较大。由于磁环120固定于转轴110的外壁，当转子转速较大时，磁环120容易相对转轴110松动，为此，在本申请的一些实施例中，转轴110还设置有用于提高与包塑件130连接强度的连接部，连接部可以是沉槽或凸筋或扁位或是其他的结构，当磁环120与转轴110通过包塑件130一体成型时，连接部能够大大提高包塑件130与转轴110的连接强度。具体的，参照图3，在本申请的一些实施例中，转轴110的外壁设置有沉槽115，当磁环120与转轴110通过包塑件130一体成型时，构成包塑件130的部分塑料嵌入于沉槽115内，使得包塑件130与转轴110之间的卡接力大大提高，从而使得磁环120能够更为稳固的安装在转轴110上，防止磁环120相对转轴110运动，提高转子结构的稳定性。It is understandable that when the rotor is working, its rotation speed is relatively high, so the moment of inertia is relatively large. Since the magnetic ring 120 is fixed to the outer wall of the rotating shaft 110, when the rotor speed is relatively high, the magnetic ring 120 is easy to loosen relative to the rotating shaft 110. For this reason, in some embodiments of the present application, the rotating shaft 110 is also provided with a connecting portion for improving the connection strength with the overmolding 130. The connecting portion can be a sink groove or a convex rib or a flat position or other structure. When the magnetic ring 120 and the rotating shaft 110 are integrally formed through the overmolding 130, the connecting portion can greatly improve the connection strength between the overmolding 130 and the rotating shaft 110. Specifically, referring to Figure 3, in some embodiments of the present application, the outer wall of the rotating shaft 110 is provided with a groove 115. When the magnetic ring 120 and the rotating shaft 110 are integrally formed through the overmolding 130, part of the plastic constituting the overmolding 130 is embedded in the groove 115, so that the clamping force between the overmolding 130 and the rotating shaft 110 is greatly improved, so that the magnetic ring 120 can be more stably installed on the rotating shaft 110, preventing the magnetic ring 120 from moving relative to the rotating shaft 110, and improving the stability of the rotor structure.
当然，沉槽115可以设置有多个，多个沉槽115沿转轴110的外壁周向间隔分布，从而可以进一步提高包塑件130与转轴110的卡接力，进一步减少磁环120的晃动。具体的，转子转动时，磁环120具有相对转轴110沿周向转动的趋势，因此可以将沉槽115设置为沿着转轴110的轴向延伸，从而使得包塑件130嵌入于沉槽115时，沿轴向延伸的沉槽115能够对卡接件提供更大的卡接力。Of course, a plurality of sink grooves 115 may be provided, and the plurality of sink grooves 115 are spaced apart along the circumferential direction of the outer wall of the rotating shaft 110, so as to further improve the clamping force between the overmolded part 130 and the rotating shaft 110, and further reduce the shaking of the magnetic ring 120. Specifically, when the rotor rotates, the magnetic ring 120 has a tendency to rotate circumferentially relative to the rotating shaft 110, so the sink groove 115 may be arranged to extend along the axial direction of the rotating shaft 110, so that when the overmolded part 130 is embedded in the sink groove 115, the sink groove 115 extending along the axial direction can provide a greater clamping force for the clamping part.
可以理解的是，磁环120在运行的过程受到较大的离心力，当磁环120运行过长时有可能会出现开裂或脱落等现象而造成转子无法正常工作，为此，参照图1，在本申请的一些实施例中，转子还包括套接件140，套接件140套接固定于磁环120的外周壁。套接件140能够在周向上对磁环120进行限位，从而有利于改善磁环120的受力情况，减少磁环120开裂或脱落的现象，而且即使磁环120出现开裂，由于套接件140的限位作用，使得磁环120不会直接脱落，从而便于进行售后的相关维护。具体的，套接件140可以是钢套，其具有较好的延展性，能较好地包裹于磁环120的外周，从而对磁环120进行限位固定。当然，磁环120也可以采用其他合适的材料制成。It is understandable that the magnetic ring 120 is subjected to a large centrifugal force during operation. When the magnetic ring 120 runs for too long, it may crack or fall off, causing the rotor to fail to work properly. For this reason, referring to FIG. 1 , in some embodiments of the present application, the rotor also includes a sleeve 140, which is sleeved and fixed on the outer peripheral wall of the magnetic ring 120. The sleeve 140 can limit the magnetic ring 120 in the circumferential direction, which is conducive to improving the force of the magnetic ring 120 and reducing the phenomenon of cracking or falling off of the magnetic ring 120. Even if the magnetic ring 120 cracks, due to the limiting effect of the sleeve 140, the magnetic ring 120 will not fall off directly, thereby facilitating related after-sales maintenance. Specifically, the sleeve 140 can be a steel sleeve, which has good ductility and can be well wrapped around the outer periphery of the magnetic ring 120, so as to limit and fix the magnetic ring 120. Of course, the magnetic ring 120 can also be made of other suitable materials.
参照图3和图5，可以理解的是，为了使得转轴110能够与叶轮310实现快速安装连接，在本申请的一些实施例中，转轴110远离密封件160的一端设置有扁位段113，叶轮310设置有与扁位段113相适配的扁孔311。安装时，将叶轮310固定，然后将扁位段113对准扁孔311***，即可以使得扁位段113插接于扁孔311内，从而将叶轮310安装在转轴110上，安装快捷方便。当然，安装时，也可以将转轴110固定，然后将扁孔311对准扁位段113，然后将叶轮310套接于转轴110上，使得转轴110插接于扁孔311内，从而实现叶轮310与转轴110的安装连接。具体的，扁位段113的厚度相对转轴110主体的厚度小，扁位段113的横截面大致呈长方形状，使得扁位段113能够卡接于扁孔311内，从而带动叶轮310转动。Referring to FIG. 3 and FIG. 5 , it can be understood that, in order to enable the rotating shaft 110 to be quickly installed and connected with the impeller 310, in some embodiments of the present application, the end of the rotating shaft 110 away from the seal 160 is provided with a flat section 113, and the impeller 310 is provided with a flat hole 311 adapted to the flat section 113. During installation, the impeller 310 is fixed, and then the flat section 113 is aligned with the flat hole 311 and inserted, that is, the flat section 113 can be inserted into the flat hole 311, so that the impeller 310 is installed on the rotating shaft 110, and the installation is quick and convenient. Of course, during installation, the rotating shaft 110 can also be fixed, and then the flat hole 311 is aligned with the flat section 113, and then the impeller 310 is sleeved on the rotating shaft 110, so that the rotating shaft 110 is inserted into the flat hole 311, thereby realizing the installation connection between the impeller 310 and the rotating shaft 110. Specifically, the thickness of the flat segment 113 is smaller than the thickness of the main body of the rotating shaft 110 , and the cross section of the flat segment 113 is substantially rectangular, so that the flat segment 113 can be snapped into the flat hole 311 , thereby driving the impeller 310 to rotate.
参照图3和图5，需要说明的是，为了进一步提高叶轮310安装在转轴110的稳固性，在本申请的一些实施例中，扁位段113的外壁还设置有限位槽114，叶轮310的扁孔311的内壁设置有与限位槽114匹配的限位筋312，当扁位段113插接于扁孔311内时，限位筋312卡接于限位槽114内，从而能够进一步提高叶轮310安装于转轴110的稳固性。具体的，限位槽114沿扁位段113的周向延伸设置，从而可以很好地限制叶轮310沿转轴110的轴向移动。当然，限位槽114可以设置多个，相应的，限位筋312也可以设置有多个，通过将多个限位筋312一一卡接于对应的限位槽114内，从而可以进一步提高叶轮310安装于转轴110的稳固性。Referring to FIG. 3 and FIG. 5 , it should be noted that, in order to further improve the stability of the impeller 310 installed on the rotating shaft 110, in some embodiments of the present application, the outer wall of the flat segment 113 is further provided with a limiting groove 114, and the inner wall of the flat hole 311 of the impeller 310 is provided with a limiting rib 312 matching the limiting groove 114. When the flat segment 113 is inserted into the flat hole 311, the limiting rib 312 is clamped in the limiting groove 114, thereby further improving the stability of the impeller 310 installed on the rotating shaft 110. Specifically, the limiting groove 114 is arranged to extend along the circumferential direction of the flat segment 113, thereby well limiting the axial movement of the impeller 310 along the rotating shaft 110. Of course, a plurality of limiting grooves 114 can be provided, and correspondingly, a plurality of limiting ribs 312 can also be provided. By clamping a plurality of limiting ribs 312 one by one in the corresponding limiting grooves 114, the stability of the impeller 310 installed on the rotating shaft 110 can be further improved.
参照图4和图6，本申请第二方面实施例提供的一种循环泵，包括电机500、电控总成200和泵头300，电控总成200和泵头300分别连接于电机500沿轴向的两端，从而能够减少电控总成200占用的径向空间，使得循环泵的体积更小。具体的，电机500包括转子、定子180、屏蔽罩150和密封件160，定子180绕设于转子的外周，屏蔽罩150罩设于转子沿轴向的一端，同时屏蔽罩150将转子与定子180隔开，屏蔽罩150内充满水或是其他需要输送的液体，转子浸泡于液体中。屏蔽罩150内布置有沿轴向分布的两个轴承170，转子设置有转轴110，两个轴承170套接于转轴110的两端，使得转子能够在屏蔽罩150内转动。屏蔽罩150设置有与转轴110的端部对应的避让孔151，密封件160可拆卸安装于避让孔151。电控总成200连接于电机500沿轴向设有密封件160的一端，电控总成200设置有避让通道210，避让通道210沿轴向贯穿电控总成200并与密封件160对应设置。泵头300设置有泵腔320，泵腔320内安装有叶轮310，叶轮310与转轴110连接。循环泵工作时，转轴110带动叶轮310转动，从而输送液体至循环管道内，实现供暖等功能。Referring to Fig. 4 and Fig. 6, a circulating pump provided by the second embodiment of the present application includes a motor 500, an electric control assembly 200 and a pump head 300, wherein the electric control assembly 200 and the pump head 300 are respectively connected to the two ends of the motor 500 along the axial direction, so as to reduce the radial space occupied by the electric control assembly 200, so as to make the circulating pump smaller in size. Specifically, the motor 500 includes a rotor, a stator 180, a shielding cover 150 and a sealing member 160, wherein the stator 180 is arranged around the outer periphery of the rotor, the shielding cover 150 is arranged at one end of the rotor along the axial direction, and the shielding cover 150 separates the rotor from the stator 180, and the shielding cover 150 is filled with water or other liquids to be transported, and the rotor is immersed in the liquid. Two bearings 170 distributed along the axial direction are arranged in the shielding cover 150, and the rotor is provided with a rotating shaft 110, and the two bearings 170 are sleeved at the two ends of the rotating shaft 110, so that the rotor can rotate in the shielding cover 150. The shielding cover 150 is provided with an avoidance hole 151 corresponding to the end of the rotating shaft 110, and the sealing member 160 is detachably mounted on the avoidance hole 151. The electric control assembly 200 is connected to one end of the motor 500 where the sealing member 160 is axially arranged, and the electric control assembly 200 is provided with an avoidance channel 210, which penetrates the electric control assembly 200 axially and is arranged corresponding to the sealing member 160. The pump head 300 is provided with a pump cavity 320, and an impeller 310 is installed in the pump cavity 320, and the impeller 310 is connected to the rotating shaft 110. When the circulating pump is working, the rotating shaft 110 drives the impeller 310 to rotate, thereby transporting liquid to the circulating pipeline to achieve functions such as heating.
当转子出现卡死等状况时，可以将工具通过避让通道210将密封件160从避让孔151拆卸出来，然后将工具伸入避让孔151内转动转轴110，从而快速解决转子卡死等问题，同时能够将泵腔320内残留的气体排出，由于循环泵在进行转子的维护时，不需要拆卸电控总成200以及泵头300等组件，因此能够在循环泵整体结构免拆卸的情况下进行相关的维护操作，从而使得维护操作非常方便，大大提高了循环泵维护的效率。When the rotor is stuck or something like that, the seal 160 can be removed from the avoidance hole 151 by using a tool through the avoidance channel 210, and then the tool can be inserted into the avoidance hole 151 to rotate the shaft 110, thereby quickly solving the problem of the rotor being stuck and the like, and at the same time, the residual gas in the pump chamber 320 can be discharged. Since the circulating pump does not need to disassemble components such as the electronic control assembly 200 and the pump head 300 when maintaining the rotor, relevant maintenance operations can be performed without disassembling the overall structure of the circulating pump, which makes the maintenance operation very convenient and greatly improves the efficiency of circulating pump maintenance.
需要说明的是，现有技术中，部分循环泵的电控总成虽然较为紧凑，但此类循环泵包括一个轴向安装空间和两个径向安装空间，其体积依旧很大，客户安装时，需要根据实际场地而更改电控总成的安装角度，造成生产以及安装的不便。而本申请的循环泵，通过将电控总成200和泵头300分别连接于电机500沿轴向的两端，安装时不再需要为解决径向角度而更改电控总成200的角度，提高安装的便利性。It should be noted that in the prior art, although the electric control assembly of some circulating pumps is relatively compact, such circulating pumps include one axial installation space and two radial installation spaces, and their volume is still large. When installing, customers need to change the installation angle of the electric control assembly according to the actual site, causing inconvenience in production and installation. However, the circulating pump of the present application, by connecting the electric control assembly 200 and the pump head 300 to the two ends of the motor 500 along the axial direction, does not need to change the angle of the electric control assembly 200 to solve the radial angle during installation, thereby improving the convenience of installation.
如图4和5所示，泵头300的外壁连接有进水管和出水管，进水管和出水管均与泵腔320连通，叶轮310转动时，带动外部液体从进水管入口330进入进水管，然后再从进水管出口进入泵腔320，排液时，液体从泵腔320从出水管入口进入出水管，然后从出水管出口340排出。为了使得泵头300受力更为稳定，在发明的一些实施例中，参照图4，进水管入口330的轴线和出水管出口340的轴线位于同一直线，从而使得液体在进水管入口330处对泵头300的冲击力与液体在出水管出口340对泵头300的反冲力基本位于同一直线，而且两者的作用方向相反，从而能够实现相互抵消，有利于提高泵头300的受力稳定性。具体的，进水管入口330的轴线还与转轴110的轴线相垂直，从而可以进一步提高泵头300的受力稳定性。As shown in Figs. 4 and 5, the outer wall of the pump head 300 is connected with an inlet pipe and an outlet pipe, both of which are connected to the pump chamber 320. When the impeller 310 rotates, it drives the external liquid to enter the inlet pipe from the inlet pipe inlet 330, and then enter the pump chamber 320 from the inlet pipe outlet. When discharging liquid, the liquid enters the outlet pipe from the outlet pipe inlet from the pump chamber 320, and then is discharged from the outlet pipe outlet 340. In order to make the pump head 300 more stable, in some embodiments of the invention, referring to Fig. 4, the axis of the inlet pipe inlet 330 and the axis of the outlet pipe outlet 340 are located in the same straight line, so that the impact force of the liquid on the pump head 300 at the inlet pipe inlet 330 and the recoil force of the liquid on the pump head 300 at the outlet pipe outlet 340 are basically located in the same straight line, and the two have opposite directions of action, so that they can offset each other, which is conducive to improving the force stability of the pump head 300. Specifically, the axis of the water inlet pipe inlet 330 is also perpendicular to the axis of the rotating shaft 110 , thereby further improving the force stability of the pump head 300 .
可以理解的是，为了提高循环泵的水力效率，在本申请的一些实施例中，出水管入口的轴线与泵头300的外壁相切，从而使得液体从泵腔320内排出时更为顺畅，减少出水的阻力，有利于提高循环泵的水力效率。It can be understood that in order to improve the hydraulic efficiency of the circulation pump, in some embodiments of the present application, the axis of the water outlet pipe inlet is tangent to the outer wall of the pump head 300, so that the liquid is discharged from the pump chamber 320 more smoothly, reducing the resistance of the water outlet, which is beneficial to improving the hydraulic efficiency of the circulation pump.

When assembling the electric control assembly 200 and the motor 500, the positioning column 220 can be inserted into the positioning groove 181, so as to achieve the functions of assembly guidance and misalignment prevention, which is conducive to improving the convenience of installation. Of course, two or more positioning columns 220 can be provided, and multiple positioning columns 220 are distributed circumferentially at intervals on the bottom wall of the electric control box.

In order to prevent liquid or other impurities from entering the electric control box and affecting the wiring, in some embodiments of the present application, referring to Figure 4, the circulating pump also includes a first sealing ring 260 and a second sealing ring 270. The first sealing ring 260 is clamped between the electric control box and the shielding cover 150, and the second sealing ring 270 is clamped between the electric control box and the stator 180. The first sealing ring 260 is located on the inner side of the wiring terminal 250, and the second sealing ring 270 is located on the outer side of the wiring terminal 250. The first sealing ring 260 and the second sealing ring 270 are both made of elastic materials, such as rubber or silicone. When the electric control assembly 200 is connected to one end of the motor 500 through the fastener 240, the first sealing ring 260 is squeezed and deformed, thereby tightly fitting the end face between the electric control box and the shielding cover 150 to achieve a sealed connection, so that when the circulating pump is in use or maintained, the first sealing ring 260 can prevent impurities such as liquid or dust from entering the electric control box from the inside; at the same time, the second sealing ring 270 is squeezed and deformed, thereby tightly fitting the end face between the electric control box and the stator 180, so the second sealing ring 270 can prevent impurities such as liquid or dust from entering the electric control box from the outside, which is beneficial to improving the waterproof and dustproof performance of the electric control assembly 200.

The air conditioner can be a HVAC system or other air conditioner capable of achieving HVAC function. The circulating pump can make water or other liquids circulate repeatedly in the pipes of the air conditioning system, overcome the resistance loss of the loop, and meet the heating needs of customers.
空调器由于采用上述的循环泵，循环泵的转子组件100通过在屏蔽罩150对应转轴110的位置设置避让孔151，密封件160可拆卸安装于避让孔151，当转子出现卡死等状况时，可以通过将密封件160从避让孔151拆卸出来，然后通过工具伸入避让孔151内转动转轴110，从而快速解决转子卡死等问题，同时能够将泵腔320内残留的气体排出，该转子组件100在维护时不需要拆卸过多的部件，维护操作非常方便，提高了转子组件100维护的效率。Since the air conditioner adopts the above-mentioned circulation pump, the rotor assembly 100 of the circulation pump is provided with an avoidance hole 151 at the position of the shielding cover 150 corresponding to the rotating shaft 110, and the sealing member 160 is detachably installed in the avoidance hole 151.
