当前,石油库越来越多地选用齿轮油泵来输送润滑油。由于泵型结构的特点,及安装和操作管理等原因,普遍反映噪音大。经对8台泵的噪音测试,6台的噪音值均在86dB以上,另2台的最低噪音值为75dB。过大的噪音和振动,不但影响设备的使用寿命,同时也危害人身健康。现就如何降低油泵的噪音值问题,提出一点粗浅的看法。 1.避免选用大流量油泵。由于润滑油的粘度较高,在管道中流动时的阻力损失也
Currently, oil depots increasingly use gear pumps to transport lubricant. Due to the characteristics of the pump structure, and installation and operation management and other reasons, generally reflect the noise. After testing the noise of 8 pumps, the noise of 6 units was above 86 dB, and the lowest of the other 2 units was 75 dB. Excessive noise and vibration, not only affect the service life of equipment, but also endanger human health. Now on how to reduce the pump noise, put forward a little superficial view. Avoid using large flow pumps. Due to the high viscosity of the lubricant, resistance loss in flowing in the pipe is also lost
