Description
This PU piston seals for mining technology is Drum-shaped ring faceing Xingzhuang Si drum, so called drum circle. It is relatively lips, and cylinder wall contact pressure generated Force and be sealed. Because it can be bi-directional sealing, simplified piston structure and shorten the length of the piston, back to back on behalf of the Y-ring design, while improving the compressive strength, the phenomenon will not turned lips. Had left it as a hydraulic support cylinder, piston seal stereotypes column structure, widely used in the hydraulic support. Rubber cloth past drum circles are gradually being polyurethane drum-ring replaced. Drum circle in the original basis Increase the guide ring to improve the capacity of the pressure drum circle, but also reduce the wear and tear the roots. For hydraulic support leg and jack piston seal.1. Contact DEF's salesman to get a quotation.( by Email, Telephone, Trademessage)
