Problems solved by technology

Existing mines usually use explosion-proof motor-driven water pumps as drainage equipment. This kind of mine drainage equipment can fully guarantee the normal drainage of the mine under normal circumstances; Then it cannot work normally, causing the entire drainage system to be paralyzed, which brings great difficulties to the life safety of underground workers and disaster relief and rescue work.
In addition, although the explosion-proof performance of the explosion-proof motor itself can meet the design standards, its power supply must reach the working position of the explosion-proof motor, so that the explosion-proof motor and water pump can work normally. Due to the harsh underground environment, the power supply line is prone to leakage or exposure. Brings a very large safety hazard to underground safety production

Abstract

The invention relates to a hydraulic double-altitude fluid pump. A hydraulic station is driven to work through a variable-frequency motor, further, a third hydraulic oil cylinder piston and a fourth hydraulic oil cylinder piston are respectively driven to act through hydraulic oil pipes, a first water inlet pipe, a second water inlet pipe, a first water outlet pipe and a second water outlet pipe are conducted or sealed in time sequence, at the same time, a first hydraulic oil cylinder piston and a second hydraulic oil cylinder piston are respectively driven to act in time sequence, water in an accommodated chamber communicated with the first hydraulic oil cylinder piston and the second hydraulic oil cylinder piston is pressed and sent to a pump body water outlet opening, and the goal of remote distance hydraulic control pumping is realized. In addition, the pump lift is high, and the efficiency is high. At the same time, the electromechanical separation can be realized, the underground use safety of the pump can be effectively improved, the hydraulic station is driven to work through the variable-frequency motor, the flow rate of the pump can be conveniently regulated according tothe actual work condition in real time, and the operation is simple and convenient. The invention has the advantages of simple and reasonable structure, convenient operation, convenient flow region, high pump lift and high efficiency. The invention is applicable to the fields such as oil field recharge, oil gas pumping, mine water drainage and the like, and is particularly suitable for water drainage of sudden mine water seepage.

Description

technical field [0001] The invention discloses a fluid pump, in particular to a hydraulic double-height fluid pump, belonging to the technical field of mechanical pump manufacturing. Background technique [0002] With the reform and opening up and the rapid development of the economy, safety production has been paid more and more attention. my country is rich in mineral resources, most of which are mined in mines. Some deposits are deep and the water volume is unstable. There are often safety hazards such as sudden water seepage and mud-rock flow submerging mines, which seriously endanger the lives of underground miners. Existing mines usually use explosion-proof motor-driven water pumps as drainage equipment. This kind of mine drainage equipment can fully guarantee the normal drainage of the mine under normal circumstances; Then it can not work normally, causing the whole drainage system to be paralyzed, which brings great difficulties to the life safety of underground wor...
