Multi section oil cylinder

Analysis on fault diagnosis and maintenance of hydraulic cylinder hydraulic cylinder is the actuating element that converts hydraulic energy into mechanical energy in hydraulic system. Its faults can be basically summarized as hydraulic cylinder misoperation, inability to push load, piston sliding or creeping, etc. The initial action of the hydraulic cylinder is slow. In the case of low temperature, the hydraulic oil has high viscosity and poor fluidity, which causes the hydraulic cylinder to move slowly. The improvement method is to replace the hydraulic oil with good viscosity temperature performance. Under low temperature, the oil temperature during startup can be improved by using a heater or using the machine itself to heat.
