What happens if you have excessive vibration in your hydraulic system?
What happens if you have excessive vibration in your hydraulic system?
If your hydraulic equipment produces excessive vibrations during normal operation, you may be in for some unpleasant surprises down the line, such as decreased performance or even system failure. If nothing else, you’ll be dealing with increased, irritating, and potentially dangerous noise levels.
What should I do if my hydraulic pump is vibrating?
If your hydraulic equipment is vibrating too much, checking the pump for proper operation and proper mounting is a good first step. In many hydraulic systems, relief, vent, or compensator valves are supposed to compensate for a cylinder bottoming out. If these valves don’t respond quickly enough, you end up with hydraulic shocks.
What causes the noise in a hydraulic system?
Taking control of noise In any hydraulic system, the pump is the main source of pulsations and vibrations. While pump manufacturers have made noise reduction a design goal, every pump still produces some ripple – the pump manufacturers’ term for pulsations. Ripple produces the line vibrations which cause additional noise.
How many times does a hydraulic piston bounce?
Depending on the severity of contact, a piston may bounce (vibrate) 3 to 4 times. Noise is the result of this vibration. In the workplace, this noise can be at best irritating; at its worst, noise can create an un-pleasant and dangerous environment, especially if it exceeds OSHA requirements.

What causes noise in a hydraulic pump line?
Valve operation, cylinder actuation and pump pulsations are just a few examples of the many factors that can contribute to hydraulic system noise. This noise can be carried and amplified through the tube lines connecting these various components.

What should I do about my hydraulic noise?
Frequently, a 90° curved hose is used when a horizontal line has to be connected to a vertical line, and 180° hose curves also are quite common. Experiments show that both of these configurations actually increase system noise level. The solution: don’t bend hydraulic hose; instead, substitute bent metal tubing.
