Adjustment and Testing of Hydraulic Cylinder

First, reduce the working pressure inside the cylinder to around (0.5-1) MPa. Then, make the piston rod perform reciprocating motion and open the exhaust plug for exhaust.

The method of opening is as follows:

When the piston reaches the end of its stroke, open the exhaust plug at the moment when the pressure rises, and immediately close it before the return begins. During the exhaust process, you can hear a hissing sound, followed by the discharge of white and turbid foamy oil. When the air is completely discharged, the oil sprayed out will be clear. Exhaust completeness can be judged with the naked eye.

If the hydraulic cylinder is equipped with an adjustable buffering device, and the piston is in motion, first set the throttle valve to a position with a lower flow rate, and then gradually adjust the size of the throttle port until the requirements are met.

In addition to performing the above adjustment tasks, it is necessary to check for oil leakage in various sealing components and whether the bolts of the connecting parts are loose, in order to prevent accidents.

Based on the usage of the hydraulic cylinder, schedule regular inspection times and maintain inspection records.

1. Adjustment of Exhaust Device:

2. Adjustment of Buffering Device: 

3. Inspection of Various Parts of the Hydraulic Cylinder: 

4. Regular Inspection: 

Alignment steps:

1.Turn lock nut towards counter clockwise with 1/4circle by wrench.

2.Using hex . wrench to adjust thealignment screw B:

1)clockwise, rod speed will be slow down

2)counter clockwise, rod speed will be up.

3.After alignment ,use hex. wrerch to fix thealignment screwB,and then tighten thecushion nut C to prevent possible

leakage from cushion seal D

4.Tighten the lock nut A

• Should the movement of a cylinder with loading is above 500mm/sec.,
• If the moving speed is higher than 750mm/sec,external reducing speed valves should be used

The application not only for production mechanical machine tools and metal processing equipment, but also can be widely used in actuators of steel, nuclear power plant control, passenger elevators, etc
