Problems solved by technology

[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 increases the inconvenience of equipment and personnel. Safety factor, the liquid pump does not have a temperature monitoring device, which is easy to cause damage to the liquid pump. When the liquid pump fails, it cannot automatically switch to another liquid pump. The emulsion dosing is manually operated, resulting in inaccurate emulsion concentration during use, shortening the The service life of the hydraulic support, the inaccurate liquid level alarm, and the inability to work in conjunction with the control system can no longer meet the higher demand for coal mining equipment in today's society
