图1为77t重型矿山自卸车前悬挂液-氮缸用塑料活塞环,其工作状况是在巨大的压力和一定的温度下承受摩擦和挤压,工作介质为液压油。这就要求活塞环首先能承受较大的压力,避免在重压下发生压溃或产生较大的变形,以保护活塞与缸体不发生直接接触而产
Figure 1 shows a 77t heavy-duty mining dump truck front suspension liquid - nitrogen cylinder with plastic piston rings, the working conditions are under great pressure and temperature to withstand friction and extrusion, the working medium is hydraulic oil. This requires that the piston ring first of all be able to withstand greater pressure to avoid crushing under pressure or have a greater deformation in order to protect the piston and the cylinder does not have direct contact with the production
