水环式真空泵定期维护
Regular maintenance of water ring vacuum pump
(1)在正常的工作中要注意检查轴承的工作和润滑情况，其温度(轴承和外圆处)比环境温度一般高出15℃~20℃为宜，最高不允许超过30℃~35℃，即轴承架外圆处实际温度不应超过55℃~60℃;正常工作的轴承每年应加油3~4次，每年至少清洗轴承一次，并将润滑油全部更换。
(1) In normal operation, pay attention to check the operation and lubrication of the bearing. The temperature (at the bearing and the outer circle) is generally 15 ℃ ~ 20 ℃ higher than the ambient temperature, and the maximum temperature is not allowed to exceed 30 ℃ ~ 35 ℃, that is, the actual temperature at the outer circle of the bearing frame shall not exceed 55 ℃ ~ 60 ℃; the bearing in normal operation shall be oiled 3 ~ 4 times a year, cleaned at least once a year, and all lubricating oil shall be replaced.
(2)在正常工作中还要定期压紧填料，如果填料因磨损而不能保证所需要的密封性能时，应更换新填料。如果采用机械密封，发现泄漏现象，应检查机械密封的动静环是否已损坏或是辅助密封老化，如出现上述情况，均需要更换新零件。
(2) In normal operation, the packing shall be pressed regularly. If the packing cannot guarantee the required sealing performance due to wear, the new packing shall be replaced. If the mechanical seal is used and leakage is found, check whether the dynamic and static rings of the mechanical seal are damaged or the auxiliary seal is aging. If the above conditions occur, new parts shall be replaced.
(3)在出现特殊声音时，可拆下两端盖上的压板，查看叶轮两端面是否与分配器研伤，还可检查排气阀板是否正常。
(3) In case of special sound, remove the pressing plate on both ends of the cover, check whether the two ends of the impeller are abraded with the distributor, and check whether the exhaust valve plate is normal.
