In order to ensure the function and quality of the hydraulic cylinder, we need to carry out a series of checks on its functions before putting it into use, how to check the hydraulic cylinder? As following:
1. Check the flow of hydraulic cylinder and pay attention to its flow speed.
2. Make sure that all pressure control valves work normally and adjust to the proper value. The safety valve shall be debugged according to the requirements of the manual. After the flow control valve is adjusted, pay attention to check the operation of the hydraulic cylinder and the hydraulic motor.
3. We need to check whether the function of the change-over valve is normal, especially for the adjustable amount of teeth such as impact and speed, which is set well. In addition, it is necessary to check the external loss of the oil tank of the hydraulic cylinder. If the internal leakage is serious, the valve should be checked. At the same time, it is also necessary to check whether the flow of the hydraulic pump is sufficient. If the function of the hydraulic pump is reduced, it is necessary to replace the new hydraulic pump in time.
4. Check the function of the solenoid valve. We can distinguish by hearing, or by touching. In addition, it is also necessary to check whether the piston seal and piston rod seal are normal, and whether the piston rod is damaged or worn. In addition, check whether the bolts of the equipment are loose and the joint of the trunnion.
The above is the inspection steps of the hydraulic cylinder. In addition, it is necessary to check the fastening of each connecting part to ensure that there is no sign of loosening. At the same time, make data statistics for the operation of the hydraulic cylinder to facilitate inspection at any time.
