Hydraulic pump noise reasons

1. Too much stress
The high pressure oil in the hydraulic system will increase the oil discharge pressure of the hydraulic pump, which will cause the discharged oil to produce sharp noise in the high-speed movement.
2. The traffic is too large or too small
When the hydraulic pump works, the flow rate is too large or too small, it will also produce too much or not enough oil movement sound, resulting in noise.
3. Not filtering enough
Impurities, water and air in the hydraulic system will hinder the flow of oil, increase the load of the pump, and increase noise during operation.
4. Poor seal
The poor seal of the parts in the hydraulic system will directly cause the leakage of the system, and then increase the noise of the pump in the work.
