Cylinders and motors
AddTime: 2015/4/6

· Cylinders have seals and rings that can be damaged by excess pressure and contaminants in the fluid. Once again, be sure that your hydraulic fluid is clean. Check the points where the cylinder rod moves in and out of the cylinder housing for leaks. Check the length of the cylinder rods for any dings, dents or other damages that could allow fluid and pressure to escape.

A cylinder is designed to take loads along its axis only. Side loads can decrease cylinder life by causing excess wear on seals and the rod.

· With hydraulic motors, as with pumps, your primary maintenance consideration is clean hydraulic oil. The gears, vanes and pistons can be abraded by contaminants, resulting in pressure loss. Before each use, check the drive shaft of the motor for any damage or leakage. Be sure that motors are started and operated at the correct rpm. The owner’s manual will provide this information.
