Hydraulic support various monoblock hydraulic valves life is very low

Hydraulic support various monoblock hydraulic valves life is very low, foreign ways and means to solve is to improve the precision filtration system and improving the quality of the emulsion, but with little success. This paper analyzes the development process Sealing valve stent, discusses the relationship Sealing materials and sealing performance. Pointed out sealing technology is the key to the hydraulic valve stainless steel fitting support life improved.
hydraulic hose machine to achieve stepless (speed range up to 2000) in a wide range, it can be in the process of running speed.hydraulic drive easily automated, because of its fluid pressure, flow, or flow direction is easy to adjust or control reasons.
