How to judge where the oil leakage of the slag scraper is leaking?

There are several ways to judge the oil leakage of the oil cylinder of the slag scraper:

1) When installing the oil cylinder, ensure that the direction of the connecting head at the top of the piston rod should be in the same direction as the cylinder head, earring (or central hinge shaft), and ensure the straightness of the entire piston rod during the process of advancing and retreating to avoid rigid interference. , causing unnecessary damage.

2) Hydraulic Cylinder Guidance:

Reasons and countermeasures for internal leakage of the oil cylinder: The cast iron ring seal allows a certain degree of internal leakage. Impurities in the hydraulic cylinder will cause premature wear of the piston seal. Replace the piston seal. If the cylinder is obviously scratched, the cylinder must be replaced. Pressurize one end of the hydraulic cylinder, open the oil port on the other end, and observe whether there is obvious internal leakage at the oil port end. Most hydraulic cylinder piston drifts may not be caused by the hydraulic cylinder. Use the above method to determine whether the hydraulic cylinder has internal leakage. It helps to identify problems with related components of the hydraulic system.

3) The hydraulic cylinder must perform multiple reciprocating operations with low pressure (greater than the starting pressure) before operation, and the normal operation can only be performed after the air in the hydraulic cylinder is discharged. The oil inlet and outlet and the joint must be fastened with a combination pad to prevent oil spill.
