Embodiment 1

[0016] Below in conjunction with embodiment and accompanying drawing, the present invention is further described in detail.

[0017] Such as figure 2 As shown, in this embodiment, the combined pump device includes a water tank 1, a pump 2, a vacuum pump 5, a water tank 6, and a control circuit. The inlet and outlet of the pump 2 are connected to the water inlet pipe 7 and the water outlet pipe 8 respectively, and the water inlet pipe 7 and the water outlet pipe 8 are respectively connected to the water tank 1 and the water tank 6, wherein the pump 2 is a magnetic pump, and the vacuum pump 5 is a micro vacuum pump. Because the waterway in this embodiment is a circulating waterway, the water tank 6 communicates with the water tank 1, and the water outlet pipe 8 is connected in parallel with a miniature vacuum pump M2. The water inlet pipe of the vacuum pump 5 is connected with a solenoid valve YV 1 3. The solenoid valve YV 1 The circuit of 3 is connected in parallel with the...

Abstract

The invention relates to a pump capable of eliminating vapour lock, which includes a pump, whose inlet and outlet are connected the liquid inlet and outlet tubes separately. A vacuum pump is connected in parallel with the liquid outlet tube and a control device is used for controlling the start and stop of the pump and the vacuum pump.

Description

technical field [0001] The invention belongs to the technical field of liquid pumps, and in particular relates to a water pump capable of eliminating air resistance. Background technique [0002] In the existing water supply system, a large number of water pumps and magnetic pumps are usually used. These pumps rely on the principle of atmospheric pressure to supply water, so the problem of air resistance in the pipeline often occurs, that is, if there is air in the pump body or the water inlet circuit of the water pump , the pump will not work properly. The common method is to place the pump below the liquid surface and let the liquid flow into the pump body by gravity. However, when the pipeline is long and thin and the power of the pump is small, the air resistance phenomenon is obvious. [0003] A utility model patent with the patent publication number CN2533298Y discloses a strong self-priming pipeline pump, which is a set of elastic diaphragm shock-type suction and exh...
