Abstract

The invention provides a pump and liquid conveying equipment. The pump comprises a pump body which comprises a liquid inlet, a first liquid outlet and a second liquid outlet. The pump body is providedwith a first cavity, a pressurization cavity, a second cavity and a third cavity which sequentially communicate. The pump body is provided with a driving mechanism, and the driving mechanism is usedfor changing the volume size in the pressurization cavity. A control valve body comprises an electromagnetic coil, a sealing shell, a valve element assembly and a valve assembly. The electromagnetic coil is used for generating electromagnetic force to drive the valve element assembly in the sealing shell to act, thus the valve assembly opens or closes a valve opening of the third cavity, and connection between the second cavity and the first cavity is opened or closed. The equipment is used in a system when the pump stops, liquid pressure in the pump cannot be rapidly released through an output end pipeline, the problem that the liquid pressure is reduced gradually is solved, the purpose of releasing the liquid pressure in the pump rapidly is achieved, air in a liquid input pipe and the pump can be exhausted as fast as possible, and the liquid absorbing efficiency is improved.

Description

technical field [0001] The invention relates to the field of liquid conveying machinery and spraying technology, in particular to a pump and liquid conveying equipment. Background technique [0002] When transporting liquid and pressurizing the liquid, a booster pump is usually used. The pump used for fluid boosting is mainly a positive displacement pump, which generates positive and negative pressure by changing the volume in the pump chamber, thereby transporting and boosting the liquid. Such as diaphragm pump, diaphragm pump is a special form of positive displacement pump. It relies on the back and forth agitation of one or more diaphragms to change the volume of the working chamber to transport and pressurize the fluid. In the spray system composed of nozzles , the diaphragm pump pressurizes the liquid and sprays it through the nozzle. When the driving mechanism is composed of a motor, when the motor in the booster pump is powered off, the internal rotor of the motor wil...
