Schematic diagram of remote (remote) liquid supply system

1. Product overview
The remote liquid supply system is a high-pressure emulsion supply, liquid return and spray water high-pressure liquid supply pipeline, which mainly provides high-pressure emulsion, support liquid return and high-pressure water for spraying for remote comprehensive mechanized coal mining in coal mines. It adopts the combination of 27SiMn seamless steel pipe and high-pressure connectors, special elbows, etc., which is convenient for turning, disassembly and maintenance, and can avoid pipeline pulse vibration caused by pressure pulsation, and the environment of the liquid supply pump station is free from moisture and dust. environment.
1.1 Product features and advantages:
 1.1.1. Since the mobile pumping station truck is no longer arranged along the groove of the working face, the difficulties in the mobile substation, pumping station pulling and moving, support, ventilation, transportation and other links caused by the high pressure of the roadway and the deformation of the floor drum have been completely solved. It effectively enhances the adaptability to complex geological conditions and reduces the constraints of production operations.
 1.1.2. For long-distance liquid supply in the mining area, it is not necessary to specially pull and move a large number of mobile substation pump station vehicles, which reduces the operation links, improves work efficiency, and also eliminates various inconveniences in the process of pulling and shifting pump station vehicles. safety factors. The belt of the working face fluctuates greatly along the middle of the groove. When the working face advances, in the process of pulling and shifting the pump station, it is very easy to break the rope and even roll over the car, which seriously threatens the life safety of the workers.
 1.1.3. The use of centralized and long-distance liquid supply effectively reduces the production and promotion operation links, and greatly improves the production efficiency.
 1.1.4. For example, the pipeline removal before moving the train and the pipeline installation and hoisting after the train is in place, the working face will no longer arrange the pump station train along the groove, which can increase the ventilation section of the roadway, reduce the ventilation resistance, and ensure the working face. The production air is of great significance to the ventilation management of the working face.
 1.1.5. Install a fixed pump station and use long-distance liquid supply, which not only saves the installation cost, but also can serve multiple working faces in the same mining area, and can also provide power source for other hydraulic equipment.
 1.1.6. In terms of power supply management, the independent power supply of the pumping station is realized. The startup and operation of the pumping station equipment no longer interferes with the working face equipment, which effectively improves the safety and reliability of the power supply of the fully mechanized mining face.
 1.1.7. In terms of equipment management, centralized liquid supply at a fixed location effectively solves the moisture-proof and anti-fouling management of pumping station equipment.
 1.1.8. In terms of safety and quality standardization construction, the one-time standard laying and hoisting of liquid supply pipelines has prevented the situation of train pipelines entangled with each other at the pump station, and improved the standardization level of electromechanical safety quality on the working face site.
