1. The viscosity of the oil in the hydraulic cylinder is 29~74mm2/S. It is strongly recommended to use the ISOVG4646 hydraulic oil.
2. The hydraulic cylinder stipulates that the system software has a precision of not less than 80um. It is necessary to strictly control the environmental pollution of the hydraulic oil, maintain the cleaning of the hydraulic oil, regularly maintain the characteristics of the hydraulic oil, and carry out the necessary careful consideration and replacement of new work. Hydraulic oil.
3. When installing, make sure that the orientation of the top connection head of the hydraulic cylinder should be consistent with the orientation of the cylinder head and the earrings, and ensure the parallelism of all hydraulic cylinders in the whole process of victory or defeat, so as to avoid the situation of stiffness influence, resulting in unnecessary damage. .
4. After the hydraulic cylinder is installed on the server, in the operation experiment, check whether there is oil leakage at the part of the oil hole and the guide sleeve, and solve the problem of oil supply at the position of the earrings and the rolling bearing of the central hinge shaft.
5. If the hydraulic cylinder has common faults such as oil leakage and needs to be disassembled, use the hydraulic working pressure to move the part of the piston rod to all the end parts of the cylinder liner. During disassembly and assembly, try to reduce unsuitable knocks and sudden changes. burst out.
6. Before disassembly and assembly, the speed regulating valve should be loosened to reduce the working pressure of the hydraulic press control circuit to zero, and then the switching power supply should be disconnected to stop the operation of the hydraulic control valve. oil hole.
7. The hydraulic cylinder cannot be used as an electrical grounding device to prevent electric shock to the hydraulic cylinder.
