Description

一种液体活塞空压机Liquid piston air compressor

技术领域Technical field

本发明涉及液体活塞装置，是一种液体活塞空压机。The invention relates to a liquid piston device, which is a liquid piston air compressor.

背景技术Background technique

空气压缩机分多种类型：机械活塞往复式空压机、螺杆式空压机、离心式空压机及漩涡式空压机等。这些空压机被广泛应用于工业生产上。经过长期使用发现，上述空压机存在的不足主要表现在以下几个方面：维护费用高、造价高、故障率较高，效率有待进一步提高等。为此，本领域技术人员开始研究使用液体活塞以解决上述不足。然而，使用液体活塞需要解决液体频繁换向问题，因为液体活塞的运转频率很高，换向频率有时候在每秒钟达到若干次。由于现有液体活塞空压装置的研究大多采用换向阀作为液体换向机构的核心部件，在液体频繁换向时，导致换向阀门频繁启闭，这使电气部分极易损坏，阀门的使用寿命较短，较难维持整个***正常运行。另外，现有的采用换向阀的液体活塞空压机的设计，管路连接复杂，使用换向阀数量多，导致造价很高；同时，换向阀间歇式或脉冲式工作，使管路***中的液体频繁出现脉动现象，引起设备强烈震动，导致设备出现运行噪音大，故障率高整体效率下降等不足，从而导致当今液体活塞空压机仅限于理论研究阶段，无法投入真正的实体运行。There are many types of air compressors: mechanical piston reciprocating air compressors, screw air compressors, centrifugal air compressors and vortex air compressors. These air compressors are widely used in industrial production. After long-term use, the shortcomings of the above-mentioned air compressor are mainly manifested in the following aspects: high maintenance cost, high cost, high failure rate, and the efficiency needs to be further improved. To this end, those skilled in the art began to study the use of liquid pistons to solve the above-mentioned deficiencies. However, the use of liquid pistons needs to solve the problem of frequent liquid commutation, because the liquid piston operates at a high frequency, and the commutation frequency sometimes reaches several times per second. Since the research of the existing liquid piston air pressure devices mostly uses the directional valve as the core component of the liquid reversing mechanism, when the liquid is frequently reversed, the reversing valve is frequently opened and closed, which makes the electrical part extremely vulnerable to damage. The use of the valve The life is short, and it is difficult to maintain the normal operation of the entire system. In addition, the design of the existing liquid piston air compressor using a reversing valve, the pipeline connection is complicated, the use of a large number of reversing valves, resulting in high cost; at the same time, the reversing valve intermittent or pulsed work, so that the pipeline The liquid in the system frequently pulsates, causing strong vibration of the equipment, causing the equipment to have high operating noise, high failure rate and overall efficiency. The current liquid piston air compressor is limited to the theoretical research stage and cannot be put into real physical operation. .

The stator in the mechanical liquid continuous reversing device of this embodiment has four through holes. Each through hole is connected to the corresponding cylinder through a pipe joint and a pipe. The opening at the top of each cylinder is connected to the air outlet pipe and the air inlet pipe, the one-way valve and the The other structures are as shown in the position in the figure and are the same as the structures described in the present invention.

图4-图6所示的实施例主要显示机械式液体连续换向装置中的转子由第一电动机55带动，水泵由第二电动机49带动。第一电机55安装在支架上，第一电机55通过连接轴53与转子2连接，连接轴53的一端位于转子2轴向中心。水泵连接轴56一端与第二电动机49连接，单向阀及其它结构均与本发明所述结构相同。机械式液体连续换向装置的供液腔通过管路连接水泵37的出水口，机械式液体连续换向装置的回液腔通过管路连接水泵37的进水口。水泵与机械式液体连续换向装置的连接管路被称作循环水主管道(简称主管道)。主管道上设有补水管。转子通过***其中心连接轴孔并穿透主管道外壁的连接轴53及联轴器与转子电机55的轴连接。定子侧壁的四个开口通过管路分别与对应的气缸(或液压罐)连接，气缸顶部分别连接进气管和排气管。进气管各自有进气单向阀，排气管各自有出气单向阀。进气管在单向阀进气侧连接统一的进气主管。排气管在单向阀出气侧连接统一的排气主管。The embodiments shown in FIGS. 4-6 mainly show that the rotor in the mechanical liquid continuous reversing device is driven by the first motor 55, and the water pump is driven by the second motor 49. The first motor 55 is mounted on the bracket. The first motor 55 is connected to the rotor 2 through a connecting shaft 53. One end of the connecting shaft 53 is located at the axial center of the rotor 2. One end of the water pump connecting shaft 56 is connected to the second motor 49, and the check valve and other structures are the same as those described in the present invention. The liquid supply chamber of the mechanical liquid continuous reversing device is connected to the water outlet of the water pump 37 through a pipeline, and the liquid return chamber of the mechanical liquid continuous reversing device is connected to the water inlet of the water pump 37 through a pipeline. The connecting pipeline between the water pump and the mechanical liquid continuous reversing device is called the circulating water main pipeline (referred to as the main pipeline). The main pipeline is provided with a water supply pipe. The rotor is connected to the shaft of the rotor motor 55 through a connecting shaft 53 inserted into its central connecting shaft hole and penetrating the outer wall of the main pipe and a coupling. The four openings on the side wall of the stator are respectively connected to corresponding cylinders (or hydraulic tanks) through pipes, and the top of the cylinders is connected to the intake pipe and the exhaust pipe, respectively. Each intake pipe has an intake check valve, and each exhaust pipe has an exhaust check valve. The intake pipe is connected to a unified intake main pipe on the intake side of the check valve. The exhaust pipe is connected with a unified exhaust main pipe on the outlet side of the check valve.

该空压机第一次开机时首先打开补水管阀门给空压机充水，当水位达到气缸的中间液位时关闭补水管阀门。这时同时启动转子电机和水泵电机。主管道内的水开始循环，转子开始旋转。为便于对本发明做详细说明，将定子侧壁管口以定子圆周顺时针方向依次命名为D1、D2、D3、D4.与之对应连接的气缸(气压罐)依次命名为Q1、Q2、Q3、Q4.当定子侧壁管口D1对应的是转子供水腔中部开口时，与主管道供水相通，D1联通的气缸Q1开始进水，这时气缸Q1内的气体被压缩并从排气管排出；同时，定子侧壁管口D1对面的管口D3对应的是转子回水腔中部开口，与回水主管相通，与之相连接的气缸Q3开始回水，这时气缸Q3开始通过进气管吸气。转子一直在连续旋转。当转子回水腔中部开口转到定子管口D1位置时，定子管口D1与主管道回水口相通，D1对应的气缸Q1开始回水，这时气缸Q1通过进气管吸气；同时D3与转子供水腔中部开口对应，与主管道进水相通，气缸Q3开始进水，这时气缸Q3内的气体被压缩并通过排气管排气。当转子不停的旋转中部开口对应另一对定子管口D2、D4时，气缸Q2、Q4也重复Q1、Q3的过程。这样，空压机的四个缸周而复始的供水、回水，同时吸气、排气，并且两对缸相互接力，不停地连续工作，不停地为用气负荷提供压缩气体或连续供风。When the air compressor is turned on for the first time, the water supply pipe valve is first opened to fill the air compressor with water, and the water supply pipe valve is closed when the water level reaches the intermediate liquid level of the cylinder. At this time, the rotor motor and the pump motor are started simultaneously. The water in the main pipe starts to circulate and the rotor starts to rotate. In order to facilitate the detailed description of the present invention, the stator side wall nozzles are named D1, D2, D3, D4 in the clockwise direction of the stator circumference. The corresponding cylinders (air pressure tanks) are named Q1, Q2, Q3, Q4. When the stator side wall port D1 corresponds to the central opening of the rotor water supply cavity, it communicates with the main pipe water supply, and the cylinder Q1 connected to D1 begins to enter the water. At this time, the gas in the cylinder Q1 is compressed and discharged from the exhaust pipe At the same time, the nozzle D3 opposite the stator side wall nozzle D1 corresponds to the central opening of the rotor return water chamber, which communicates with the return water main pipe, and the connected cylinder Q3 starts to return water. At this time, the cylinder Q3 starts to suck through the intake pipe gas. The rotor has been rotating continuously. When the central opening of the rotor return water chamber turns to the position of the stator nozzle D1, the stator nozzle D1 communicates with the main pipe return water port, and the cylinder Q1 corresponding to D1 begins to return water. At this time, the cylinder Q1 draws air through the intake pipe; The opening in the middle of the sub-water supply chamber corresponds to the inlet water of the main pipe, and the cylinder Q3 starts to enter the water. At this time, the gas in the cylinder Q3 is compressed and exhausted through the exhaust pipe. When the rotor's non-stop rotating middle opening corresponds to another pair of stator nozzles D2, D4, the cylinders Q2, Q4 also repeat the process of Q1, Q3. In this way, the four cylinders of the air compressor repeatedly supply and return water, simultaneously inhale and exhaust, and the two pairs of cylinders relay each other, continuously working, providing compressed gas or continuous air supply for the gas load. .

本发明所述结构的空压机，转子电机与水泵电机互不干扰，协同工作，单独控制，可以使用定型产品水泵，有利于水泵的快速批量供应，对提高生产效率和质量控制有一定益处。In the air compressor of the structure of the present invention, the rotor motor and the water pump motor do not interfere with each other, work cooperatively, and are individually controlled. The shaped product water pump can be used, which is beneficial to the rapid mass supply of the water pump and has certain benefits for improving production efficiency and quality control.

共用泵电机驱动形式：该空压机整体运行原理及管路连接方式与单独电机驱动转子的空压机相比，工作原理一样。不同之处在于，它省去了带动转子的单独电机，采用转子与水泵共轴的方式。也就是说，转子与水泵涡轮采用同一根传动轴连接或通过联轴器连接在一起，用同一台电机带动。这样的优点是空压机的结构更加紧凑，部件进一步减少；其不足是，由于牵涉到主轴连接问题，配套水泵需要专门定制，无法采用已定型的标准化产品。另外，转子转速与水泵转速完全同步，在设计制造时控制方式及气缸设计容量与单独电机驱动转子的空压机都不尽相同。Common pump motor drive form: The overall operation principle and pipeline connection mode of this air compressor are the same as those of the air compressor driven by a single motor. The difference is that it eliminates the need for a separate motor that drives the rotor, and uses the rotor and pump to be coaxial. In other words, the rotor and the pump turbine are connected by the same drive shaft or connected by a coupling, and driven by the same motor. This advantage is that the structure of the air compressor is more compact, and the components are further reduced; the disadvantage is that due to the problems involving the connection of the main shaft, the matching water pump needs to be specially customized, and the standardized products that have been stereotyped cannot be used. In addition, the rotor speed is completely synchronized with the water pump speed. The control method and cylinder design capacity during design and manufacturing are different from the air compressor that drives the rotor by a separate motor.

图7-图9所示实施例主要示意机械式液体连续换向装置中的转子及叶轮15的动力均来自于循环液体的动能，液体由水泵转动产生动能，转子的转速由叶轮参数和循环水参数共同决定。即：转子的转动不需要外接动力，转子的转动由水流推动。这种结构是水泵主轴不与机械式液体连续换向装置的转子直接连接的一种配合方式，其结构及各部件的位置关系均不改变。The embodiment shown in FIGS. 7-9 mainly shows that the power of the rotor and the impeller 15 in the mechanical liquid continuous commutation device comes from the kinetic energy of the circulating liquid. The liquid is generated by the rotation of the water pump, and the rotor speed is determined by the impeller parameters and the circulating water. The parameters are determined together. That is: the rotation of the rotor does not require external power, and the rotation of the rotor is driven by the water flow. This structure is a kind of cooperation mode in which the main shaft of the water pump is not directly connected to the rotor of the mechanical liquid continuous reversing device, and the structure and the positional relationship of each component are not changed.

本实施例的机械式液体连续换向装置的回液腔开口与水泵泵体58的进水口连接，机械式液体连续换向装置的供液腔开口通过循环水主管道51与水泵泵体58的出水口连接，机械式液体连续换向装置的定子壁上开设4 个通孔，该通孔分别通过管道与相应的气缸连接，各气缸顶端开口分别连接出气管和进气管，各进气管与气缸的进气口间分别连接进气单向阀，各进气单向阀进气侧进气管连接进气主管，进气主管的进气口朝向电动机44或电动机的散热装置，便于电机散热；各出气管与气缸出气口间分别连接出气单向阀，各出气单向阀出气侧出气管连接出气主管。与转子相连为一体的轴上安装涡轮15和推力轴承16，转子的出水端处安装推力轴承16。其它结构与本发明所述结构相同。本实施例的空压机其运行原理与上述实施例相比，管路连接方式与运行原理一样，唯一不同之处是：采用涡轮带动的机械式液体连续换向装置，转子转动由自身的涡轮通过主管道循环水冲动提供动力，没有专用电机，也不使用水泵电机直接带动。这样做的优点是整体结构紧凑，水泵可以采用定型产品批量采购；缺点是转子转速由水泵流速压力流量及涡轮叶片多个参数确定，设计时转子几何尺寸及气缸容量确定较繁琐。The opening of the return chamber of the mechanical liquid continuous reversing device of this embodiment is connected to the water inlet of the pump body 58 of the pump, and the opening of the liquid supply chamber of the mechanical liquid continuous reversing device is connected to the pump body 58 of the pump through the circulating water main pipe 51 The water outlet is connected, and four through holes are opened on the stator wall of the mechanical liquid continuous reversing device. The through holes are respectively connected to the corresponding cylinders through pipes. The openings at the top of each cylinder are connected to the air outlet pipe and the air inlet pipe respectively. The air intake check valves are connected between the air intake ports, and the intake side intake pipe of each air intake check valve is connected to the air intake main pipe. The air intake port of the air intake main pipe faces the motor 44 or the heat sink of the motor, which is convenient for the motor to dissipate heat; An air outlet check valve is connected between the air outlet pipe and the cylinder air outlet, and the air outlet pipe of the air outlet side of each air outlet check valve is connected to the air outlet main pipe. A turbine 15 and a thrust bearing 16 are installed on a shaft integrally connected to the rotor, and a thrust bearing 16 is installed at the water outlet end of the rotor. The other structure is the same as the structure described in the present invention. The operating principle of the air compressor of this embodiment is the same as that of the above embodiment. The pipeline connection is the same as the operating principle. The only difference is that the mechanical liquid continuous reversing device driven by the turbine is used, and the rotor rotates by its own turbine. It is powered by the impulse of circulating water in the main pipeline, and there is no special motor, nor directly driven by the pump motor. The advantage of this is that the overall structure is compact, and the pump can be purchased in batches with fixed products; the disadvantage is that the rotor speed is determined by the pump flow rate pressure flow and multiple parameters of the turbine blade, and the rotor geometry and cylinder capacity are more cumbersome in design.

图10-图12是本发明另一实施例，该实施例的特点在于机械式液体连续换向装置的转子与水泵涡轮结构设计成一体。转子与轴连为一体，轴的两端安装涡轮，转子的进水口处安装推力轴承16。转子的转动由电动机带动，其它结构与本发明所述结构相同。本实施例的空压机运行原理与上述实施例相同。只是该机械式液体连续换向装置将水泵涡轮与转子完全结合为一体，采用同一电动机拖动，结构最为紧凑，转子转速与涡轮转速同步。采用该结构的空压机循环水主管既可以象上述几种空压机一样采用单根粗大主管，也可以在机械式液体连续换向装置供水口和水泵出水口分出多个管口，并多根管道并连，以利于液体散热；同时，循环水多管并连且呈辐射状均布的结构更有利于设备重心的平衡，减小震动；更有利于水管和气管空间的分布安排。10-12 are another embodiment of the present invention. This embodiment is characterized in that the rotor of the mechanical liquid continuous reversing device and the structure of the water pump turbine are integrated. The rotor is connected with the shaft as one, the turbine is installed at both ends of the shaft, and the thrust bearing 16 is installed at the water inlet of the rotor. The rotation of the rotor is driven by the electric motor, and other structures are the same as those described in the present invention. The operating principle of the air compressor of this embodiment is the same as the above embodiment. It is just that the mechanical liquid continuous reversing device completely integrates the water pump turbine and the rotor, adopts the same electric motor to drive, and has the most compact structure, and the rotor speed is synchronized with the turbine speed. The circulating water main pipe of the air compressor adopting this structure can adopt a single thick main pipe like the above-mentioned air compressors, or can divide multiple pipe ports at the water supply port and the water pump outlet of the mechanical liquid continuous reversing device, and Multiple pipes are connected in parallel to facilitate the heat dissipation of the liquid. At the same time, the structure in which the circulating water is connected in parallel and distributed uniformly is more conducive to the balance of the center of gravity of the equipment and reduces the vibration.

本发明所述机械式液体连续换向装置中定子的周壁开设两个或两个以上的通孔，各通孔在圆周上均布，每个通孔均与相应的连接管连接。定子为圆筒状，圆筒的上下两端面分别安装法兰，使其与其它部件连接。附图31-图34所示是定子实施例之一的结构，定子1包括一个圆筒9，圆筒9上的四个连接管与圆筒9上的四个通孔相连通，圆筒9的一端安装圆环10，圆环10的外径与圆筒9的外径相同，圆环10内径与转子2端部开口内径相同。附图31中11-2是外接法兰。In the mechanical liquid continuous reversing device of the present invention, two or more through holes are opened in the peripheral wall of the stator, and each through hole is evenly distributed on the circumference, and each through hole is connected to a corresponding connecting pipe. The stator is cylindrical, and flanges are installed on the upper and lower ends of the cylinder to connect it with other components. Figures 31-34 show the structure of one of the embodiments of the stator. The stator 1 includes a cylinder 9, four connecting pipes on the cylinder 9 communicate with the four through holes on the cylinder 9, the cylinder 9 A ring 10 is installed at one end of the ring, the outer diameter of the ring 10 is the same as the outer diameter of the cylinder 9, and the inner diameter of the ring 10 is the same as the inner diameter of the opening of the rotor 2 end. In Fig. 31, 11-2 is an external flange.

本发明所述的转子的结构如图19-图22、图23-图26及图27-图30所示，这些结构是转子2不同的实施例。转子2的基本结构如图27-图30所示，转子是圆柱体。转子有三种实施方式，本发明不限于这三种方式。实施例一：转子2内壁设置腔室，转子2的周壁上开设两个通孔，转子的腔室内设置隔板3，隔板3将转子2的腔室分成两个独立的小腔室，即：供水腔和回水腔，可称为第一独立小腔室34、第二独立小腔室35。通常情况下两个独立小腔室的体积相等，特殊情况下可以根据实际需要设置独立小腔室的不同体积。本发明所述的每个独立的小腔室均与对应的通孔相通，第一独立小腔室34与第一通孔37对应连通，第二独立小腔室35与第二通孔36对应连通。采用堵板封闭独立小腔体一端。第二堵板33将第一独立小腔室34一端封闭，第一独立小腔室34的另一端为敞口；第一堵板4将第二独立小腔室35一端封闭，第二独立小腔室35另一端为敞口。第二堵板33与转子2的下端口位于同一平面内，第一堵板4与转子2的上端口位于同一平面内，隔板3与第二堵板33及第一堵板4连为一体，隔板3也可以与第二堵板33及第一堵板4为分体制造，然后分别安装。The structure of the rotor according to the present invention is shown in FIGS. 19-22, 23-26, and 27-30. These structures are different embodiments of the rotor 2. The basic structure of the rotor 2 is shown in FIGS. 27-30, and the rotor is a cylinder. There are three embodiments of the rotor, and the invention is not limited to these three methods. Embodiment 1: A cavity is provided on the inner wall of the rotor 2, two through holes are formed on the peripheral wall of the rotor 2, and a partition 3 is provided in the cavity of the rotor. The partition 3 divides the cavity of the rotor 2 into two independent small chambers, namely : The water supply chamber and the return water chamber can be called a first independent small chamber 34 and a second independent small chamber 35. Generally, the volumes of two independent small chambers are equal, and in special cases, different volumes of independent small chambers can be set according to actual needs. Each independent small chamber according to the present invention communicates with a corresponding through hole, the first independent small chamber 34 corresponds to the first through hole 37, and the second independent small chamber 35 corresponds to the second through hole 36 Connected. A plugging plate is used to close one end of the independent small cavity. The second blocking plate 33 closes one end of the first independent small chamber 34 and the other end of the first independent small chamber 34 is open; the first blocking plate 4 closes one end of the second independent small chamber 35 and the second independent small The other end of the chamber 35 is open. The second blocking plate 33 and the lower port of the rotor 2 are in the same plane, the first blocking plate 4 and the upper port of the rotor 2 are in the same plane, and the partition plate 3 is connected to the second blocking plate 33 and the first blocking plate 4 as a whole The partition 3 can also be manufactured separately from the second blocking plate 33 and the first blocking plate 4 and then installed separately.

转子2的周壁上开设两个通孔，这两个通孔在转子周壁上对称分布。两个通孔为方形孔，两个方形孔在转子的周壁上以中轴为中心对称分布。方形孔可以是正方形、长方形。转子周壁上的通孔也可以是椭圆形、圆形孔等。Two through holes are formed in the peripheral wall of the rotor 2, and the two through holes are symmetrically distributed on the peripheral wall of the rotor. The two through holes are square holes, and the two square holes are symmetrically distributed on the circumferential wall of the rotor with the central axis as the center. The square hole can be square or rectangular. The through holes in the rotor peripheral wall may also be elliptical or circular holes.

转子2上的两个独立小腔室分别是回水腔和供水腔。转子2周壁上开设的两个通孔位于转子2高度的中部位置，与定子周壁通孔在高度上相同。两通孔在转子外圆弧线的净间距大于或等于定子周壁通孔在定子周壁内圆所占的弧长为优选，以防止供回水在某一定子管口处形成串流，造成能量损失。The two independent small chambers on the rotor 2 are the return water chamber and the water supply chamber, respectively. The two through holes formed on the peripheral wall of the rotor 2 are located at the middle of the height of the rotor 2 and are the same in height as the through holes of the stator peripheral wall. The net distance between the two through holes in the outer arc of the rotor is greater than or equal to the arc length of the stator peripheral wall through holes in the inner circumference of the stator peripheral wall. It is preferred to prevent the supply and return water from forming a series flow at a certain stator nozzle, causing energy loss.

图19-图22所示是转子实施例之二结构示意图，转子腔室内的隔离部件是三元流线渐变结构，它可以是倾斜板，主要是用倾斜板将转子的腔室直接隔成两个独立小腔室。如图所示倾斜板的两端头厚度较大，起到堵板的作用，起到隔离液体使转子的腔室分成两个独立小腔室的作用。转子的两个独立小腔室在其圆周上对称分布，两个独立小腔室使用时形成回水腔和供水腔，这种结构可使液体的进出更顺畅，流体阻力进一步降低。Figures 19-22 show a second structural schematic of the rotor embodiment. The isolating component in the rotor chamber is a ternary streamline gradual structure. It can be an inclined plate. The inclined plate is mainly used to directly divide the rotor chamber into two. Independent small chambers. As shown in the figure, the thickness of the two ends of the inclined plate is large, which acts as a blocking plate and isolates the liquid from the rotor chamber into two independent small chambers. The two independent small chambers of the rotor are symmetrically distributed on its circumference. When used, the two independent small chambers form a return water chamber and a water supply chamber. This structure can make the liquid flow in and out more smoothly, and the fluid resistance is further reduced.

附图23-附图26所示是转子是实施例之三，这种结构在转子2的高度方向两端分别安装了第一圆环5和第二圆环6，第一圆环5和第二圆环6可以与转子一体制作，也可以分体制作，分别安装，增设两个圆环可以增加转子上下两端的腔室体积，便于适于多种装置安装使用本发明所述换向装置。增加的圆环的高度根据使用要求设定，圆环高出的腔室，采用三元流线渐变式导流体、隔板及堵板相连，使液体的供入与回流通道流体阻力降低。图24中所示的第一导流体31与第一堵板4相连，两者可做成分体，也可制成一体，但是第一导流体31位于腔室内边沿的板面以曲面过度至第一堵板4，第一导流体31的曲面形状以能够与第一堵板4相连、起到密封独立小腔室为目的的同时，尽可能使第一圆环5的腔室具有较大的体积，便于安装传动部件等结构，第一导流体31的曲面形状还以能够最大可能降低流体阻力为设计目的。第二导流体32与第二堵板33相连，第二导流体32其结构形状及作用等均与第一导流体31相同。图24所示的实施例可以将第一导流体31、第一堵板4、隔板3、第二堵板33及第二导流体32做成一体，这些部件组合完成的功能是将转子腔室隔成两个独立的小腔室，与转子周壁上开设的通孔形成液体的供回通道，并使液体流动阻力进一步降低，同时，便于安装多种形式的传动部件。当将导流体、隔板及堵板做成分体时，将各部件按照其功能逐一安装。本发明图24所示第一导流体31和第二导流体32的曲面形状是优选方案之一，当其做成直角形或不规则等形状时，虽然也能起到与堵板或隔板连接封闭独立小腔室的目的，但其对流体的阻力较大。当根据需要安装较复杂传动结构需要圆环内的较大空间时，也可以不安装导流体。Figures 23-26 show that the rotor is the third embodiment. In this structure, the first ring 5 and the second ring 6 are installed at both ends of the rotor 2 in the height direction. The second ring 6 can be made integrally with the rotor, or can be made separately, and installed separately. The addition of two rings can increase the volume of the chamber at the upper and lower ends of the rotor, which is suitable for the installation of a variety of devices using the commutation device of the present invention. The height of the increased ring is set according to the requirements of use. The chamber above the ring is connected by a ternary streamline gradual flow guide, a baffle plate, and a blocking plate to reduce the fluid resistance of the liquid supply and the return channel. The first flow guide 31 shown in FIG. 24 is connected to the first blocking plate 4. The two can be made into a single body or can be made into one body, but the plate surface where the first flow guide 31 is located on the inner edge of the chamber is curved to The first blocking plate 4 and the curved surface shape of the first flow guide 31 can be connected to the first blocking plate 4 to seal the independent small chamber, and at the same time, the chamber of the first ring 5 should be as large as possible It is easy to install transmission components and other structures. The curved shape of the first fluid guide 31 is also designed to reduce the fluid resistance as much as possible. The second flow guide 32 is connected to the second blocking plate 33. The structure, shape and function of the second flow guide 32 are the same as those of the first flow guide 31. In the embodiment shown in FIG. 24, the first flow guide 31, the first blocking plate 4, the partition plate 3, the second blocking plate 33, and the second flow guide 32 can be integrated into one body. The chamber is divided into two independent small chambers, and the through hole formed in the peripheral wall of the rotor forms a liquid supply and return channel, and the liquid flow resistance is further reduced, and at the same time, it is easy to install various forms of transmission components. When the flow guide, the partition plate and the blocking plate are combined into components, install each component one by one according to its function. The curved shapes of the first flow guide 31 and the second flow guide 32 shown in FIG. 24 of the present invention are one of the preferred solutions. When they are made into a right angle shape or an irregular shape, although they can also play a role in blocking plates or partitions The purpose of connecting the closed small chamber, but its resistance to the fluid is greater. When installing a more complex transmission structure as required and requiring a larger space in the ring, the fluid guide may not be installed.

For example, the middle shaft 13 is installed in the middle of the structure shown in Figs. 35-38. The middle shaft 13 is a hollow shaft connected with the isolating component. One end of the middle shaft 13 is provided with a head 14 and the other end is open for connecting an external drive shaft. . This structure can realize the mechanical drag operation of the commutation device of the present invention.

本发明所述的“供水腔”和“回水腔”中的“供”还是“回”，不是由自身确定，而是看腔室高度位置连接开口管道连接的是水泵的出水口还是进水口。如果该腔室开口连接的是水泵出水口，则该腔室被称作“供水腔”，另一腔室连接水泵的进水口被称作“回水腔”；反之，亦然。"Supply" or "return" in the "water supply chamber" and "return water chamber" described in the present invention is not determined by itself, but depends on whether the height of the chamber is connected to the open pipe and is connected to the outlet or inlet of the pump . If the opening of the chamber is connected to the outlet of the water pump, the chamber is called the "water supply chamber", and the inlet of the other chamber to the water pump is called the "return water chamber"; vice versa.

由于本发明实施例泵体习惯上称作“水泵”，故本文描述转子结构时有“供水腔”或“回水腔”的称谓；这里的“水”，代表的是所有可用于本发明工作的液体，并非局限于“水”。Because the pump body of the embodiment of the present invention is conventionally referred to as a "water pump", the description of the rotor structure in this article has the title of "water supply chamber" or "return water chamber"; "water" here represents all that can be used for the work of the present invention The liquid is not limited to "water".

本发明所述的“上”和“下”均以图示位置为参考。The "upper" and "lower" in the present invention refer to the illustrated positions.
