What is the reason for the 500 tons double acting hydraulic jack ram to sink itself after lifting it?

What is the reason for the 500 tons hydraulic jack ram to sink itself after lifting it up? 
When we use a 500 tons double acting hydraulic jack, we sometimes find that after the jack is lifted, there are different degrees of decline and the speed is uneven. What is the reason for this phenomenon? What to do? Below we analyze several possibilities that arise:
 

500 tons hydraulic jack


1. It is possible that the seal of the 500 tons double acting hydraulic jack ram is damaged. Check the seal for damage.
2. There may be rust spots and fall off on the inner wall of the 500 tons double acting hydraulic cylinder of the hydraulic jack ram. Because it affects the degree of sealing, check the inner wall of the hydraulic cylinder ram.

3. It is possible that the seal ring of the hydraulic control valve connected to the 500 tons hydraulic jack is damaged or blocked. Check whether the seal of the hydraulic control valve is damaged or blocked.
4. It is possible that the hydraulic oil is lacking, which is not enough for the standard of the 500 tons double acting hydraulic jack ram, so that it will drop by itself.
5. It is possible that there is a cylinder expansion, and the cylinder expansion phenomenon may occur, so that the product manufacturer can replace the 500 tons hydraulic cylinder.
