The invention relates to an intelligent emulsion pump station used in the mine, which belongs to a safe production equipment of coal excavation and comprises an emulsion tank, an emulsion pump, an emulsion pipeline, an emulsion pump station controller. The invention is characterized in that: the emulsion pump station controller comprises a primary control circuit, a secondary control circuit and a PLC programmable controller system control circuit; a pressure sensor (8), a liquid level sensor (14),a concentration sensor (15) and an oil level sensor (18) are arranged in the emulsion tank; a temperature sensor (5) is arranged on an emulsion pump (25); the pressure sensor (8), the liquid level sensor (14),the concentration sensor (15) and the oil level sensor (18) and the temperature sensor (5) are connected with the emulsion pump station controller through a cable. The pumping station adopts constant pressure variable feed liquid, speed control by frequency variation and intelligent control, the two pumps can mutually switch over automatically; the liquid level and the oil level are controlled automatically, the temperature of the emulsion pump is supervised automatically, the safe pressure relief protection and the automatic liquid blending improves the service life of the hydraulic support, highlights the explosion proof security in the coal mine; the working performance is reliable and the operation of the pumping station is economical and energy-saving.
Description
technical field [0001] An intelligent emulsion pumping station for mines belongs to safety production equipment for coal mining, and specifically relates to an intelligent emulsion pumping station for mining used in supports for mining in coal mines. Background technique [0002] Coal is my country's basic energy and an important raw material for various industries. In recent years, with the rapid development of the national economy, coal products have grown rapidly. How to ensure the reliability, safety, energy saving and consumption reduction of mining equipment, and meet the requirements of environmental protection is the guarantee An important part of the sustainable development of the coal industry, the main problems existing in the mining emulsion pump station at present are that the control process cannot be intelligent, the power consumption is large, and the hydraulic system cannot automatically release the pressure when it is shut down for maintenance, which increase...
