图示的轴承轴封装置,可供给转子流量计轴承高于被测液体压力的润滑油,还可防止固体粉末等混入轴承。以往,轴承轴封装置有油封、机械油封。但前者效果不佳,后者则价格昂贵。本轴承轴封装置,克服了以往轴承轴封 The illustrated bearing seal assembly provides lubricant to the rotor flow meter bearing above the fluid pressure being tested and also prevents solid powder from mixing into the bearing. In the past, the bearing shaft seal device has a seal, mechanical seal. However, the former is ineffective and the latter is expensive. The bearing shaft seal device, to overcome the previous bearing shaft seal
