Emulsification pump accumulator for mining

How to improve emulsion pump stability in coal mining face?

Using advanced intelligent control method to realize the real-time response of emulsion pump under different working conditions is the key to improve the stability of fluid supply in the face. However, the current intelligent fluid supply technology in the coal mining face cannot ensure the speed and stability.

What is the fluid supply system of full-mechanized coal mining face?

The fluid supply system of full-mechanized coal mining face consists of emulsion pump station, accumulator station, fuel tank, fluid supply and return pipeline and its accessories, etc. As the power source, the emulsion pump station can supply fluid and power for the hydraulic support of the working face 1.

Can emulsion pump station control the fluid supply system at the working face?

The control method of emulsion pump station in the fluid supply system of the working face is the key to realize the stable fluid supply technology of the working face. In this paper, a new on-line adaptive learning technique is proposed to design the optimal tracking control of the fluid supply system at the working face.

Why is accumulator station important in coal mining?

It can only play an auxiliary role to upgrade the long-distance fluid supply circuit and configure an accumulator station in terms of improving the stability of fluid supply in the coal mining face. But it can reduce pressure loss, alleviate hydraulic shock, and compensate system flow to a certain extent.

Can emulsion pump control reduce energy consumption?

Ting and Hong 5 studied the coal mining face fluid supply system, and obtained a conclusion that controlling the start and stop of the emulsion pump based on pressure sensor can effectively reduce energy consumption. Zhao et al. 6 proposed an intelligent variable frequency speed control system to reduce the energy consumption of the station.

What is emulsion pump station?

Scientific Reports 13, Article number: 20002 (2023) Cite this article Emulsion pump station is widely used to provide power for full-mechanized coal mining face equipment.
