Hydraulic cylinder Use and maintenance of
1. Using Oil cylinder manufacturer The viscosity of working oil is 29~74mm2/S. ISO VG46 anti-wear hydraulic oil is recommended. The operating oil temperature is - 20~80. C range. When the ambient temperature and service temperature are low, the hydraulic cylinder can choose the oil with lower viscosity.
2. It is required that the filtration accuracy of the system shall not be less than 80um, the oil pollution shall be strictly controlled, the oil shall be kept clean, the oil performance shall be checked regularly, and necessary fine filtration and new working oil shall be carried out.
3. During installation, ensure that the direction of the connecting head at the top of the piston rod is consistent with the direction of the cylinder head, the ear ring (or the middle hinge shaft), and ensure the straightness of the entire piston rod in the process of moving forward and backward to prevent the phenomenon of rigid interference and unnecessary damage.
4. After the hydraulic oil cylinder is installed on the main engine, first check whether there is oil leakage at the oil port piping part and the guide sleeve, and oil should be added to the ear ring and the middle hinge shaft bearing.
5. In case of oil leakage and other faults, the piston shall be moved to any end of the cylinder by hydraulic pressure. Improper knocking and sudden falling shall be avoided as far as possible during disassembly.
