我厂XK199—SMΦ600气水分离器,在试生产的两年时间里,不能自动排放滤液,致使滤液从水环式真空泵里排出,造成真空泵的严重磨损。通过试验,发现不能自动排放的主要原因是浮桶上部的胶垫尺寸过大。当真空度为600汞柱时,该胶垫受到的引力,比浮桶(Φ300×30)的浮力大 I plant XK199-SMΦ600 gas-water separator, in the pilot production of two years, can not automatically discharge the filtrate, resulting in the filtrate from the water ring vacuum pump discharge, resulting in serious wear and tear on the vacuum pump. Through the test and found that the main reason can not be automatically discharged because the upper part of the float pad size is too large. When the degree of vacuum is 600 Hg, the pad is subjected to the gravitational force larger than that of the float (Φ300 × 30)
