等特种车辆设计、开发、销售于一体的大型综合现代化企业。 A large modern enterprise specializing in the design, development and sales of special vehicles such as cranes, small and medium-sized cranes, car cranes, and cranes .
The effect of different types of cranes will be different. When selecting a crane, select it according to the operating requirements. During the use of an 8-ton crane, an oil leakage fault will occur. What is the reason?
I. Reasons for leakage:
1. The O-ring at the joint between the cylinder block and the end cover is damaged or aged.
2. Oil leakage between the piston rod and the relative moving surface of the guide sleeve.
Solution: If the piston rod is strained, you can clean the shaft with gasoline, wait until it is dry, and then apply 101 type AB glue to the grooves and pits that are damaged. Be sure to make the grooves and pits Point down to prevent the glue from running out. At the end, move the piston rod oil seal on the piston rod back and forth twice to scrape off the excess glue. After the glue has completely solidified, it can be put into use.
Second, the reason for leakage:
1. The static seal O-ring between the piston rod and the piston is damaged or aged.
2. The dynamic seal between the piston and the cylinder wall fails.
Solution: To prevent the piston from stopping in a certain position and moving too far, if it is too large, it is regarded as a serious internal leakage, and the O-ring must be replaced in time; if the internal leakage of the piston and the cylinder wall parts, the external A new piston with a larger diameter than the original size.
