Problems solved by technology

The load of the hydraulic conveying system is low, and the power factor becomes smaller, which is also the main reason for the low efficiency of the power supply system in the hydraulic conveying system
[0009] Since the type selection of the emulsification pump is designed according to the most unfavorable conditions, the maximum flow rate and the corresponding pressure, and in the actual movement, due to the change of the working surface conditions, the emulsification pump mostly works at low load. In the past, the opening of the pump outlet valve The size of the emulsified liquid is adjusted to adjust the flow and pressure of the emulsion, which consumes a lot of energy and has a large impact on machinery (such as emulsification pumps, valves), which increases the loss of machinery.

Abstract

The invention discloses a mining energy-saving emulsion pump station and a control method thereof. The station comprises an emulsion pump. A liquid inlet tube of the emulsion pump is connected to a liquid storage tank. A liquid outlet tube of the emulsion pump is connected to a drive oil cylinder for a plurality of columns of hydraulic supports. The drive end of the emulsion pump is connected to a variable frequency intelligent industrial motor through a coupling. The liquid outlet tube is connected with a hydraulic sensor. According to the mining energy-saving emulsion pump station and the control method thereof, the outlet hydraulic pressure can be monitored in real time through the hydraulic sensor, accordingly the intelligent industrial motor is controlled to make pressure and flow rate change, the stability of pressure variation of the liquid outlet tube is achieved, the service life of equipment is greatly prolonged, and the mining energy-saving emulsion pump station further has the characteristics of being simple in structure and low in cost.

Description

technical field [0001] The invention relates to a mining energy-saving emulsion pump station and a control method thereof, belonging to the technical field of mine emulsion pump stations. Background technique [0002] The emulsion pump station is the power source of the support equipment of the underground comprehensive coal mining face, and it is also an indispensable tool for the replacement and maintenance of the support operation. The emulsion pump is a very necessary link to realize the safe operation of the coal mine underground. Because the emulsion pump has the characteristics of uniform flow, stable pressure, stable operation, high strength, small pulse, low oil temperature, low noise, and convenient use and maintenance, it is also widely used in pipeline cleaning, workpiece cleaning, glass cleaning, engineering excavation, etc. . [0003] The emulsion pump station is the power device of the hydraulic support of the key support equipment in the mechanization of co...
