Abstract:

In this paper, from the analysis of the difference between electro-hydraulic control special concentrated liquid with oil emulsion, the introduction of Xiegou Coal Mine , and analysis of the application of high efficiency working face of traditional emulsified oil as the transmission medium problems, it is in urgent need of the application of special concentrated liquid. The electro-hydraulic control special concentrated liquid has excellent anti-corrosion, anti rust and lubricating performance, can effectively avoid clogging filter, filter and valve parts, prolong the service life of the equipment, improve work efficiency, and belong to the environmental friendly products. Generally, it has more economic benefit. Through the long-term tracking electro-hydraulic control special concentrated liquid on the surface of application in 18113 fully mechanized, the actual results are also verified the practical value of special concentrated liquid.

Key words: the electro-hydraulic control, concentrated liquid, high efficiency working face.
