Portable large-flow pump station device

Abstract

A portable large-flow pump station device comprises a hydraulic control system and a pneumatic control system. In the hydraulic control system, water is divided into two channels after flowing through a liquid inlet, a ball valve, a pneumatic operated directional valve, an automatic emulsion proportioning instrument and a one-way valve, the first channel of water directly flows into a hydraulic prop via a pneumatic operated switch handle and a three-purpose valve, and the second channel of water flows through a pressure intensifier controlled by a pilot operated directional control valve, and then flows into the hydraulic prop via the pneumatic operated switch handle and the three-purpose valve. In the pneumatic control system, after compressed air flows through an air inlet opening, one channel of the compressed air enters the pressure intensifier via the pilot operated directional control valve, and the other channel of the compressed air enters the pneumatic operated directional valve via the pneumatic operated switch handle. The portable large-flow pump station device is light in weight and convenient to use and maintain, workload of underground coal mine temporary supports is reduced effectively, and construction and production costs are reduced; and the efficiency is high, when in no load, low-pressure and large-flow emulsion is provided to enable the portable large-flow pump station device to act quickly and effectively, when in load, the portable large-flow pump station device is switched on, construction speed is increased, and moreover, the portable large-flow pump station device is high in safety, is energy-saving and environment-friendly, and has a wide application prospect.

Description

technical field [0001] The invention relates to a pumping station device, in particular to a portable large-flow pumping station device, which is applied to a single hydraulic prop used for temporary support construction in underground coal mines. Background technique [0002] The single hydraulic prop is an essential device for underground temporary support construction, and is widely used in the temporary support of mine roadways. However, most of the existing underground pumping stations that provide power for single hydraulic props are 60-70KW high-power pumping stations, which weigh about 1.5 tons and are inconvenient to move; The pressure of the pump is very small, and it only bears a large load in a short time, so a large part of the power provided by the existing high-power pumping station is wasted, resulting in losses. Moreover, the temporary support location will often change, and the overweight pumping station will seriously affect the construction efficiency, i...

However, most of the existing underground pumping stations that provide power for single hydraulic props are 60-70KW high-power pumping stations, which weigh about 1.5 tons and are inconvenient to move; The pressure is very small, and it only bears a large load in a short time, so a large part of the power provided by the existing high-power pumping station is wasted, resulting in losses

Moreover, the location of the temporary support will change frequently, and the overweight pump station will seriously affect the construction efficiency, increase the production cost and the workload of the workers
