[0041] The working principle of the installation structure of a water pump mechanical pressure switch of the utility model:

[0042] When the water pump mechanical pressure switch installation structure is used;

[0043] The mechanical pressure switch of the water pump is installed on the threading installation port at the tail end of the pump body through a double-head lead-out screw sleeve. The mechanical pressure switch of the water pump adopts a rear-mounted installation method. The traditional installation is that the mechanical pressure switch of the water pump is directly installed on the pump body. If the water pump or pipeline leaks, water can easily enter the switch and cause the risk of leakage short circuit, affecting the normal operation of the water pump.

[0046] When the pressure in the pump chamber drops to the starting pressure value set by the switch, the pressure switch automatically turns on the power supply, and the water pump starts to work to pressurize the pipeline, achieving the effect of automatic start and stop of the water pump;

[0047] Ensure the working state of the water pump when facing different pump chamber pressures, improve the working efficiency of the water pump, and extend the service life of the water pump.
