Abstract

The invention discloses an anti-siphon structure of a self-priming pump, and relates to the technical field of self-priming pumps. The anti-siphon structure comprises a water pump, a base is arrangedat the bottom of the water pump, a water outlet pipe is fixedly installed on one side of the water pump, a water inlet pipe is fixedly installed on the other side of the water pump, a check valve is fixedly installed in the middle of the water inlet pipe, an anti-siphon pipe is fixedly installed on the outer side of one end of the water inlet pipe, and a connecting pipe is fixedly installed on oneside of the anti-siphon pipe. According to the anti-siphon structure of the self-priming pump, the pressure between the water pump and the water inlet pipe is conveniently adjusted, so that the pressure between the inner cavity of the water pump and the water inlet pipe can reach balance after a driving motor stops working, the siphon is effectively prevented, the vibration generated by the driving motor can be buffered, and thus the driving motor is prevented from producing large noise in the working process.

Description

technical field [0001] The invention relates to the technical field of self-priming pumps, in particular to an anti-siphon structure of self-priming pumps. Background technique [0002] Self-priming water pump is a kind of water pump. Its principle is to fill the pump casing with water before starting the pump. After starting, the impeller rotates at high speed to make the water in the impeller channel flow to the volute. At this time, the inlet forms a vacuum to make the water enter When the check door is opened, the air in the suction pipe enters the pump and reaches the outer edge through the impeller channel. Through repeated circulation, the air in the suction pipe is gradually exhausted, and the water enters the pump to complete the self-priming process. [0003] At present, during the use of self-priming water pumps, it often happens that the electronically controlled exhaust valve does not close well, or the electronically controlled components fail, so that the wate...
