Daily maintenance and maintenance of hydraulic cylinders for gantry hydraulic machines

1. During the use of the hydraulic cylinder of the gantry hydraulic machine , the oil should be replaced regularly, and the filter of the hydraulic system should be cleaned regularly to ensure its cleanliness and thereby extend its service life.

2. Each time the oil cylinder is used, it is necessary to perform 5 strokes of full contraction and full extension test operation, and then carry out load operation. This can exhaust the air in the hydraulic system and preheat the various systems, which can effectively avoid the hydraulic pressure. The presence of moisture and air in the system can cause scorching in the cylinder block, which can damage the seals and cause malfunctions such as leakage in the cylinder.

3. The outer surface of the piston rod must be well protected to prevent damage to the seal due to collision and scratches. It is also necessary to often clean the dust seal position of the oil cylinder dynamic seal and the exposed sand on the piston rod to prevent sticking on the surface of the piston rod Dirt that is difficult to clean up enters the inside of the cylinder, thereby damaging the piston, cylinder barrel or seal.

4. Control the temperature of the hydraulic system. If the oil temperature is too high, the service life of the seal will be reduced. If the oil temperature is too high for a long time, it will cause long-term deformation of the seal, even in severe cases.

5. Always lubricate each connection position to prevent rust or abnormal wear in the absence of oil.

6. For each thread, bolt and other connection positions on the hydraulic cylinder of the gantry hydraulic machine, always check the connection position, and tighten it if it is found loose.
