Do you know how to solve the noise problem of the hydraulic pump? The main reasons are: the oil filter of the hydraulic pump, the suffocation of the oil inlet pipe or the high viscosity of the oil can cause the vacuum at the oil inlet of the pump to be too high,hydraulic pump causing the atmosphere to penetrate Ooze. The oil seal on the shaft end of the hydraulic pump or the pilot pump is damaged,hydraulic pump or the oil inlet pipe is not well sealed, which constitutes an atmosphere to enter. The oil level in the oil tank is too low, causing the oil inlet pipe of the hydraulic pump to be directly emptied. When there is relatively high noise in the work of the hydraulic pump, the above-mentioned parts should be finished introspection first,hydraulic pump and the invention achievements should be dealt with in time.
Excessive wear and tear of the internal components of the hydraulic pump,hydraulic pump such as the wear and tear of the cylinder block and the valve plate, the rotor and the blade of the hydraulic pump, cause serious leakage in the hydraulic pump,hydraulic pump and the flow will be generated when the hydraulic pump outputs high pressure and small flow oil Pulsating, causing higher noise. At this time,hydraulic pump the deflection angle of the variable mechanism of the pilot system can be appropriately increased to improve the influence of internal leakage on the output flow of the pump. The piston that controls the flow of the hydraulic pump will also pulsate due to the wear and tear of the department, which will cause the fluctuation of the output flow and pressure of the hydraulic pump,hydraulic pump which will cause greater vibration and noise at the pump outlet. At this time, the brush-plating, research,hydraulic pump or replacement process can be completed for the components with severe wear and strain.
The hydraulic pump valve plate is also one of the important components that easily cause noise. Due to surface wear or sludge accumulation in the opening of the unloading groove during use of the valve plate,hydraulic pump the unloading groove will be shortened and the unloading position will be changed, resulting in oil trapping and higher noise. In the process of abnormal repair,hydraulic pump the distribution plate repaired by flat grinding will also have the consequence of shortening the unloading groove. At this time,hydraulic pump if it is not properly slender in time, it will also produce a lot of noise.
