一、液压泵的噪声水平液压泵的噪声与结构、转速、工作压力等因素有关。目前,低噪声泵的噪声已达下式水平。L=50+14LogWW——液压泵输出功率(kW);L——离液压泵1m 处的噪声值(dB(A));噪声为60dB(A)或低于60dB(A)的液压泵,可认为是低噪声泵;超过90dB(A)的液压泵被认为是高噪声泵。液压泵的输出功率正比于转速n、进出口压差⊿p、排量q。试验表明⊿p 与n 对液 First, the noise level of the hydraulic pump Hydraulic pump noise and structure, speed, working pressure and other factors. At present, the noise of low noise pump has reached the following level. L = 50 + 14 LogWW - hydraulic pump output power (kW); L - noise level (dB (A)) at 1 m from the hydraulic pump; hydraulic pump with 60 dB (A) Can be considered a low noise pump; more than 90dB (A) of the hydraulic pump is considered a high noise pump. The output power of the hydraulic pump is proportional to the speed n, import and export pressure ⊿ p, displacement q. Experiments show ⊿ p and n on the liquid
