Hydraulic double-high submerged plunger-type fluid pump

Abstract

The invention discloses a hydraulic double-high submerged plunger-type fluid pump which comprises a hydraulic station and a plunger-type fluid pump, wherein the plunger-type fluid pump comprises a cylinder barrel, a plunger-type piston, a water inflow check valve and a water inflow and drainage chamber; and two water drainage ports of the plunger-type fluid pump are communicated through a water outlet three-way pipe, and two plunger ends of the plunger-type piston of the plunger-type fluid pump are communicated in series by adopting a pressure-reducing flow guide pipe. According to the invention, the serial connection mode of two oil pipes of two single pump oil cylinders for oil supply is adopted, thus plungers in two single pump cylinder barrels operate up and down, the plungers in a pump body are driven by two oil cylinder piston rods to perform reciprocating motion, and the fluid pump is suitable for productive water drainage in fields of coal mine, non-coal mines and the like, is especially suitable for emergency relief water drainage and the mine recovery by drainage for water bursting events in a mining process, and provides a strong guarantee for the production safety and disaster relief of the coal mines.

Description

Technical field: [0001] The invention relates to a fluid pump, in particular to a hydraulic double high submerged plunger type fluid pump. Background technique: [0002] With the rapid development of society, safety production and technical equipment are getting more and more attention from all over the world. my country is rich in mineral resources, most of which are mined in mines, while the underground environment is complex and changeable, and is often threatened by natural disasters such as gas, water, and fire, which seriously endanger the lives of underground miners. Disaster capability is weak, and mining accidents occur frequently. Therefore, it is imperative to strengthen the safety production conditions and technical equipment transformation of mining enterprises to eliminate potential safety hazards. [0003] Explosion-proof motor-driven water pumps are usually used as drainage equipment for mine drainage, emergency rescue and disaster relief, and drainage and mi...

AI Technical Summary

Problems solved by technology

However, when the explosion-proof motor of the water pump is submerged in water, it cannot work normally, which can cause the entire drainage system to be paralyzed; because the underground environment is relatively harsh, the power supply line is also prone to phenomena such as exposure, leakage, and ignition during operation, resulting in gas failure in the underground mine. High areas lead to gas explosions, increase underground safety hazards, and bring great difficulties to disaster relief work

[0004] In order to meet the requirements of working conditions, the submersible pumps used in large mines must use relatively large power pumps to meet the required flow and head. However, the existing impeller pumps or turbo pumps are large in size and heavy in weight. It takes a long time to install and use, and consumes huge resources, materials and manpower. The use and operation are cumbersome, and it is not easy to be flexible. In addition, although the existing piston pump can meet the head requirements, the displacement is small, the drainage is intermittent, and the efficiency is low.
