What are the causes of noise in hydraulic pump and how to reduce noise

(1) Causes of noise caused by the hydraulic pump 1. Pump flow pulsation and pressure pulsation cause vibration of pump components 2. The suction chamber suddenly communicates with the pressure chamber or the pressure chamber suddenly communicates with the suction chamber, resulting in abrupt changes in flow and pressure. Noise 3. Cavity phenomenon 4. Sudden expansion, contraction, sharp turn, etc. of the flow path in the pump 5. Mechanical reasons, such as unbalanced rotating parts, etc. (2) Measures to reduce noise 1. Eliminate drastic changes in internal oil pressure in the pump 2. Set the accumulator at the outlet of the pump to absorb the pump flow and pressure pulsation 3. The pump installed on the tank should be damped with a rubber pad 4. The upper section of the pressure pipe should be connected with the pump and pipeline by high pressure hose. Vibration isolation 5. To prevent cavitation, the use of larger diameter suction pipe, to prevent the oil mixed with air, etc. Anhui Zhongrui Machine Tool Manufacturing Co., Ltd.
