What would cause a hydraulic cylinder to not retract?

Worn or Damaged Piston Seals

Having insufficient hydraulic fluid in your system causes cylinders to become hydraulically locked and unable to fully retract or extend. Worn seals can also cause misalignment issues between the seal and cylinder rod, which may cause trouble when retracting hydraulic cylinders.

How do you stop a cylinder from drifting?

In addition to the lock valve, the spool in Valve 2 must be a float center type, venting both cylinder ports to tank when the spool is centered. The lock valve will prevent cylinder drift in either direction.

What causes a hydraulic cylinder to move?

Hydraulic cylinder drift can be caused by an internal leak in the cylinder across the piston or an external leak. When internal leaks occur, the hydraulic fluid physically moves from one side of the piston to the other, creating an uneven distribution that causes the cylinder to move or “drift.”

How do you fix a stuck hydraulic cylinder?

Therefore, they won't fly down like they fly up without a load and can even get stuck so they won't move down at all. Try this: Spray the top of the cylinders with a good penetrating oil, and let it soak a few hours. Work the cylinder up and down. The penetrating oil will usually do the trick.

What will happen if there is air trapped in the hydraulic system?

When air contaminates a hydraulic fluid, usually via the pump's inlet, aeration, cavitation, or foaming can occur. Aeration is bad news, as it degrades the hydraulic fluid causing damage to the components of the system due to loss of lubrication, resulting in overheating and burning of the seals.

What is hydraulic relief valve?

A relief valve is a device used to limit pressure in one or more locations in a hydraulic circuit. ... In short, a relief valve is a hydraulic component designed to limit pressure in an entire system or subcircuit by diverting pressurized flow to the reservoir.

How do you get moisture out of a hydraulic system?

Vacuum distillation employs a combination of heat and vacuum to remove water from hydraulic fluid. At 25 inches Hg, water boils at 133°F (56°C). This enables water to be removed at a temperature that does not damage the oil or its additives.

Why are my hydraulics slow?

A: Noise, elevated temperatures and slow or erratic operation are all signs of problems with your hydraulics system. The most common causes of poor hydraulic performance are particulate contamination, water contamination, clogged filters, high fluid temperature and incorrect hydraulic fluids.

What is repacking a cylinder?

A repacking kit

Repacking kits contain replacement parts for various components of the cylinder. Often, parts are damaged upon disassembly; it's important to keep replacement parts on hand so the lift can be reassembled and used immediately.

Can a hydraulic cylinder freeze?

Hydraulic fluid freezing point is -10° F, below which renders the fluid unusable. Even when temperatures are above the freezing point, the viscosity of the oil can increase in thickness, making it harder to use.
