Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that: in the unloaded state, since the emulsion pump is still running and continues to supply liquid to the outside, when the liquid discharge volume of the pressure relief device is less than the liquid supply volume of the pump, the pump and the liquid supply A hydraulic pressure value will still be maintained in the system, the pump is not in a zero-load operation state, and still has a certain hydraulic power consumption

Abstract

The invention relates to a pressure relief device and a pressure relief system for an emulsion pump station, and relates to the field of hydraulic pipeline pressure relief. The pressure relief device comprises a mounting seat mounted at one end, close to a liquid suction valve, of a plunger pump and a pressure relief rod slidably connected in the mounting seat, one end of the pressure relief rod extends out of the mounting seat. When the pressure relief rod slides in the mounting seat, a valve element of the liquid suction valve on the plunger pump can be ejected open to achieve pressure relief. The pressure relief device and the pressure relief system for the emulsion pump station have the effects that an emulsion pump can run in a zero-load mode in the pressure relief state, and hydraulic power consumption is reduced.

Description

technical field [0001] The present application relates to the field of hydraulic pipeline pressure relief, in particular to a pressure relief device and a pressure relief system for an emulsion pumping station. Background technique [0002] Emulsion pumping station is a kind of equipment installed underground in coal mines to provide hydraulic power source for hydraulic equipment. It consists of two parts: emulsion pump and liquid tank. The emulsion pump is a plunger pump. When the hydraulic equipment is out of service or the amount of liquid is reduced, the hydraulic pressure in the liquid supply system will increase. When it rises above the set value, it will affect the normal operation of the hydraulic equipment. Therefore, it is necessary to drain the hydraulic system in time. pressure. [0003] The plunger pump drives the slider to make a reciprocating linear motion through the crank connecting rod, and uses the pressure change in the cylinder to make the suction valve...
