Abstract

The utility model provides a constant-pressure centralized liquid supply system for a fully mechanized coal mining face of a coal mine, which is timely and rapid in reaction and short in treatment time, and can always enable the emulsion concentration, the emulsion liquid level, the emulsion working pressure and the like to be in a normal range. A pure water tank (3), a pure water pump, an automatic liquid preparation tank (4), a mixed liquid pump, an emulsified liquid tank (5) and a liquid inlet of an emulsification pump (6) are sequentially communicated, a liquid outlet of the emulsification pump (6), a high-pressure filter station (7), a liquid supply station (8) and a liquid inlet of a hydraulic support (9) are sequentially communicated, and a liquid outlet of the hydraulic support (9), a liquid return filter station (10) and the emulsified liquid tank (5) are sequentially communicated. The emulsified concentrated oil supply pump is communicated with the automatic liquid preparation tank (4) through an emulsified concentrated oil supply pipe (17), concentration sensors (15) and liquid level sensors (14) are arranged in the automatic liquid preparation tank (4) and the emulsified liquid tank (5), and pressure sensors are arranged at a liquid outlet of the emulsifying pump (6) and a liquid inlet of the hydraulic support (9).
