(1) The cause of noise in the
hydraulic pump
① The flow pulse and pressure pulse of the pump causes the vibration of the pump component
② Suddenly connected the oil -absorbing cavity to the oil cavity or the sudden interlinity of the oil cavity and the oil -absorbing cavity, generating flow and pressure mutations, and noise.
③ Poor acupoint phenomenon.
④ The cross -section of the pump inner runway suddenly expands, shrinks, and turns rapidly.
⑤ Mechanical reasons, such as the unbalanced part of the rotation, etc.
(2) How to reduce the noise of the
hydraulic pump
① Eliminate the sharp changes in oil pressure inside the pump.
② Set the storage device at the exit of the pump to absorb pump flow and pressure pulse.
③ The pump installed on the fuel tank should use rubber pads to reduce vibration.
④ A high -pressure hose with a high pressure pipe in the oil pipe is used to vibrate the connection of the pump and the pipeline.
⑤ To prevent the phenomenon of the acupuncture, the oil absorption pipe with a large diameter is used to prevent the oil from mixed in the oil Air, etc.
