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.

In order to improve the mining efficiency, reduce the amount of roadway excavation, and enhance the safety of mine production, based on the distributed parameter model, this paper studies the remote liquid supply pipeline and remote liquid supply technology in the fully mechanized mining face of the working face coal mine.

Introduction to the core of the long-distance (remote) liquid supply pipeline system in the fully mechanized coal mining face UHV steel pipe connector is also known as UHV pipe card or UHV pipe connector. This product is mainly used for the distance liquid supply system of fully mechanized coal mine working face, the remote liquid supply system, and the remote liquid supply system of fixed pump station in fully mechanized coal mine working face. Pipe connection, this product belongs to a kind of grooved pipe connection. It adopts multi-groove connection technology, the working pressure can reach 37.5Mpa, and the rated pressure can reach 63Mpa. The product has the advantages of fast and efficient installation of grooved connection technology. The long-distance liquid supply system for the fully mechanized coal mine face is a pipeline system used to transport the emulsion for the hydraulic support of the fully mechanized coal mine face. The efficiency of surface mining has been recognized by major mining groups and has been vigorously promoted and applied. The long-distance liquid supply system of fully mechanized coal mine working face includes emulsion inlet pipeline, emulsion return pipeline and spray pipeline.

According to the pipe length and flow rate of the fully mechanized coal mine face remote liquid supply system, the pipe diameter should be reasonably selected to make the pressure loss meet the requirements.

Remote liquid supply pipeline Specifications: (1) Inlet pipe Ф1O2×4000×11mm (2) Liquid return pipe Ф121×4000×8mm

The groove type special valve for remote liquid supply, namely the groove type ultra-high pressure gate valve, is mainly used for the long-distance pipeline of the fully mechanized mining face of the coal mine and the remote centralized liquid supply pipeline system of the coal mine to transport the emulsion or high-pressure water.

Generally, the safety valve can be vented on the spot, and the vent should be more than 1 meter (m) above the operator and should not be directed to the open flame location, sparking location and high temperature equipment within 15 meters (m). The safety valve vents of indoor equipment and containers should be led out of the roof and should be more than 2 meters (m) above the roof.

Remote (distance) liquid supply system for fully mechanized coal mine face The core seal is: high performance remote liquid supply seal

So today Weifang Weitel Pipe Industry Co., Ltd. is here to talk about the people who love to use ultra-high pressure steel pipe connectors, why do this, why, and how ultra-high pressure steel pipe connectors are used for pipeline connection, I hope it will be helpful to everyone .

Technical features of the remote liquid supply system:1. The mechanized high-pressure fluid control device selects pipes of different diameters according to the requirements of different mines for the emulsion to meet the liquid supply requirements of the working face and ensure the requirements of the emulsion pressure and flow of the working face.
