How do you fix a bent hydraulic cylinder?
In most cases, bent rods can be straightened in a press. It is sometimes possible to straighten hydraulic cylinder rods without damaging the hard-chrome plating, however if the chrome is damaged, the rod must be either re-chromed or replaced.
What causes a cylinder to drift from its normal position?
Piston seal leaks can cause a cylinder to drift from its normal position. To check the seal, pressurize one side of the piston and observe leakage from the opposite side. Virtually no air should leak past pistons equipped with soft seals. Replace seals as needed. Other circuit leaks also can cause a cylinder to drift.
Can a leaking piston seal cause a hydraulic cylinder to drift?
A popular misconception involving hydraulic cylinders is that if the piston seal is leaking, the cylinder will drift. While a leaking piston seal can be the root cause of cylinder drift, the physics involved are often misunderstood.
How does hydraulic drift cause an imbalance in pressure?
When problems arise, hydraulic drift – more specifically, hydraulic cylinder drift – is often the culprit. This is the result of unequal pressure created by internal leaks in the cylinder across the piston. How hydraulic drift happens The fluid flows from one side of the piston to the other, creating an imbalance.
What causes a piston to drift in a car?
If the piston seals are not leaktight, this may also cause the cylinder to drift either under the influence of valve spool leakage or reactionary load against the piston rod. This type of drift can sometimes be minimized under certain conditions of operation: Figure 5.
