Schwing piston ram is made of premium rubber, and it work at delivery cylinder with piston pin. The piston moves back and forth in the cylinder barrel. Therefore, the fit between the piston and the cylinder barrel should be appropriate, neither too tight nor too large a gap. If the fitting is too tight, it will not only increase the minimum starting pressure and reduce the mechanical efficiency, but also easily damage the sliding fitting surface of the cylinder barrel. Excessive gap will cause internal leakage of the hydraulic cylinder, reduce volumetric efficiency, and make the hydraulic cylinder fail to meet the required design performance.
Tensile Strength | Elongation at Break | Tensile Permanent Deformation | Tear Strength | Akron Abrasion |
>32 MPa | >400% | <35% | >50 Kn/M | <35% |
Caution: For the work of replaced the piston, the engine must be turned off before operating in the water tank.
