我厂以往一直采用汽油超声波清洗电表的宝石轴承座,每年要耗费国家大量宝贵的航空汽油。而且,由于航空汽油内残存着一些不挥发物,所以经清洗的宝石轴承座虽去净了油污,都留下了这些不挥发物。经烘干后,在40倍放大目镜下观看即能发现白花等残余物。 I plant in the past has been using petrol ultrasonic cleaning meter gem bearing seat, each country to spend a lot of valuable aviation gasoline. Moreover, due to the residual gas in the gasoline there are some non-volatile matter, so the cleaning of the gem bearing although the net net oil, have left these non-volatile. After drying, the 40 magnification eyepiece can be found under the observation of white flowers and other residues.
