具体实施方式Detailed ways
下面将对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.
如图1和图2所示，本发明实施例包括：As shown in FIG. 1 and FIG. 2, the embodiment of the present invention includes:
一种无水自吸辨别水流的超静音智能水泵，包括泵体1、电机3、叶轮4、减震支架5以及底座6，所述的电机3设置在导流盘2的后端，所述的叶轮4设置在导流盘2与电机3之间，所述的减震支架5设置在泵体1和底座6之间。本实施例中，所述的泵体1上设置有导流盘2，所述的泵体1和导流盘2采用一体结构，与常规泵体设计不同，常规泵体设计导流盘与泵体分开设计，然后再装配浪费工时，并且固定不好容易打转，损失性能，本实施例中泵体内设计有导流盘，导流盘与泵体设计成一体，装配简单，性能稳定。An ultra-quiet and intelligent water pump capable of discriminating water flow without self-priming, comprising a pump body 1, a motor 3, an impeller 4, a shock-absorbing bracket 5 and a base 6, the motor 3 is disposed at the rear end of the deflector 2, The impeller 4 is disposed between the deflector 2 and the motor 3, and the shock-absorbing bracket 5 is disposed between the pump body 1 and the base 6. In this embodiment, the pump body 1 is provided with a deflector disc 2, and the pump body 1 and the deflector disc 2 adopt an integrated structure, which is different from the conventional pump body design. The conventional pump body is designed with a deflector disc and a pump. The design of the body is separate, and then the assembly is wasteful of man-hours, and the fixing is not easy to rotate, and the performance is lost. In this embodiment, a deflector is designed in the pump body. The deflector and the pump body are integrated into one body. The assembly is simple and the performance is stable.
其中，所述的泵体1上设置有进水口11、出水口12、注水堵头13和拉环14，所述的进水口11和出水口12分别设置在泵体1的左右两侧边，所述的注水堵头13和拉环14均设置在泵体1的上端。The pump body 1 is provided with a water inlet 11, a water outlet 12, a water injection plug 13 and a pull ring 14. The water inlet 11 and the water outlet 12 are respectively disposed on the left and right sides of the pump body 1. The water injection plug 13 and the pull ring 14 are both disposed on the upper end of the pump body 1.
常规自吸泵每次在抽水之前必须在泵体加满水和泵体内设有射流器来满足自吸条件，为了克服这些缺陷，本发明在导流结构上解决了这一难题，如图3所示，所述的导流盘2采用密封性单出口结构，所述的导流盘2上设置有导流盘出水口21、导流盘进水口22和导流孔23，所述的导流盘出水口21设置在导流盘2外侧，导流孔23设置在导流盘进水口22和导流盘出水口21之间。其中，所述的导流孔23的直径为1-50mm。工作时叶轮4在高速旋转下进口处形成真空状态，由于导流盘2属于密封性单出口结构，此时导流孔23与叶轮4的进口处形成一个开路循环，带动气流循环流动，叶轮4的进口处负压越来越大，此时水会通过大气压力作用下被吸入导流盘进水口22在进入泵体1，然后通过叶轮4的高速离心作用下排出泵体1。Conventional self-priming pumps must be filled with water in the pump body and an ejector must be provided in the pump body to meet the self-priming conditions before pumping water. In order to overcome these shortcomings, the present invention solves this problem on the diversion structure, as shown in Figure 3 As shown, the deflector 2 adopts a sealed single-outlet structure. The deflector 2 is provided with a deflector water outlet 21, a deflector water inlet 22, and a deflector hole 23. The flow plate water outlet 21 is arranged outside the flow plate 2, and the flow hole 23 is provided between the flow plate water inlet 22 and the flow plate 21. The diameter of the diversion holes 23 is 1-50 mm. During operation, the impeller 4 forms a vacuum at the inlet under high-speed rotation. Since the deflector 2 belongs to a sealed single outlet structure, at this time, the guide hole 23 and the inlet of the impeller 4 form an open circuit cycle, which drives the air circulation to flow. The impeller 4 The negative pressure at the inlet of the pump is getting larger and larger. At this time, water will be sucked into the deflector inlet 22 under the effect of atmospheric pressure into the pump body 1 and then discharged out of the pump body 1 by the high-speed centrifugal action of the impeller 4.
形成自吸条件的关键因素在于高转速的叶轮，由于长期处于高转速下摩擦，机械密封会迅速发热，如果没有合适的散热条件，橡胶或塑料很快被高温熔化，密封就会失效，为了解决这一难题，本实施例如图4所示，在叶轮4进口处开 设一个直径为1-30mm的引流孔41，利用叶轮4进口处负压的原理，工作时水会被吸入引流孔，同时在叶轮4旋转的作用下冷却水会不断循环到机械密封上，机械密封就得到循环水的散热。The key factor for the formation of self-priming conditions is the high-speed impeller. Due to friction at high speed for a long time, the mechanical seal will heat up quickly. If there is no proper heat dissipation conditions, the rubber or plastic will be melted quickly by high temperature, and the seal will fail. This problem, as shown in FIG. 4 in this embodiment, a drainage hole 41 with a diameter of 1-30 mm is opened at the inlet of the impeller 4. Using the principle of negative pressure at the inlet of the impeller 4, water will be sucked into the drainage hole during work, and at the same time When the impeller 4 rotates, the cooling water will be continuously circulated to the mechanical seal, and the mechanical seal will be radiated by the circulating water.
如图5所示，所述的减震支架5采用雁型减震支架，所述的减震支架5上设置有安装孔51。常规水泵在工作时由于电机本身的震动和水流会形成很大的噪音，水泵在高振幅作用下螺丝会松脱、整体会位移，一段时间后电机失效，为了解决这一难题本发明结合大雁肢体的平衡性和延展性来解决这一难题。As shown in FIG. 5, the shock-absorbing bracket 5 is a goose-type shock-absorbing bracket, and the shock-absorbing bracket 5 is provided with a mounting hole 51. When a conventional water pump works, the motor itself will generate a lot of noise due to the vibration and water flow of the motor.
