Problems solved by technology

When the length of the drainpipe is long, after turning on the submersible pump, you need to walk a certain distance to reach the valve at the end of the drainpipe. At this time, the submersible pump is already in operation, but the water pumped out is not used. Increase the pressure in the submersible pump
This pressure rise will only cause waste of electricity when the pressure is low, and will damage the submersible pump when the pressure is high

Abstract

A pressure control device for a submerged pump comprises a sealed motor cabin and a pressure switch, wherein the motor cabin is provided with an opening; an elastic part is hermetically arranged at the opening; the pressure switch is arranged in the motor cabin; the pressure switch comprises a press device and a microswitch; the press device comprises a pressure-bearing column and a reset spring; one end of the pressure-bearing column is arranged in correspondence to the elastic part and the other end of the pressure-bearing column is against the reset spring; and a downward pressing part of the pressure-bearing column corresponds to a button of the microswitch. The pressure control device has the advantages of simple structure and convenience for operation.

Description

technical field [0001] The invention relates to a pressure control device for a submersible pump, in particular to a pressure control device for controlling the closing of the submersible pump. Background technique [0002] Submersible pump (Submerged pump) is a water treatment tool in which the pump body and the motor can be immersed in water. The difference between submersible pumps and ordinary pumps is that submersible pumps work underwater, while most pumps work on the ground. The working principle of a common centrifugal submersible pump is: before the submersible pump is started, the suction pipe and the submersible pump must be filled with liquid. After starting up, the impeller rotates at high speed, and the liquid in the submersible pump rotates with the impeller. Under the action of centrifugal force, it flies away from the impeller and shoots out. The speed of the injected liquid in the diffusion chamber of the pump casing gradually slows down, and the pressure ...
