In the design of production and manufacturing of hydraulic top, cylinder, piston rod, hydraulic seal is a very important stage, in all customers, long-term application how to maintain the hydraulic top piston rod surface scar?

What can cause hydraulic top piston rod surface scars?

Stumbles and bruises; When the hydraulic cylinder is in normal operation, the automobile mechanical jack is hit on the piston rod.

The organization around the waste cylinder rod is too hard, personal safety is not balanced, and the piston rod is hurt by hand-held special tools.

To tighten or remove the relevant parts of the master cylinder, immediately clamp the piston rod with pipe pliers.

Step or tread carelessly. Large, small and medium-sized hydraulic roof in transport easy to knock injury for various reasons.

Safeguard measures:

In the hydraulic top, especially in the piston rod around the additional safety protection; Maintenance, installation of mechanical jacks to the application of special type or special tools, do not try to be arrogant, engineering construction address when please irrelevant items, as far as possible to make the place wide; When removing the piston rod and the piston rod coupling, it is forbidden to rack jack to clamp the piston rod immediately, and to cushion the red copper skin and other soft items.

When installing the hydraulic top cylinder, it is necessary to center it first and then insert it to prevent knock on the piston rod. It is forbidden to use the rigid wire cable to lift the piston rod immediately. When placing or transporting the piston rod, use packing cloth to bind the rod to maintain and improve the strength of the hydraulic piston rod, and the surface heat treatment should reach the required value.
