我厂循环水系统使用兰州水泵厂生产的IS200-150-400清水泵,24h连续运转。泵轴承由N46机械油飞溅润滑,原轴承密封型式是间隙密封。由于泵长时间运行,轴承的损坏造成密封处间隙增大或损坏,引起润滑油大量泄漏,不仅造成润滑油的浪费,而且影响泵的运行。更换密封就需把轴承压盖全部 I plant recycling water system using Lanzhou Pump Factory production IS200-150-400 water pump, 24h continuous operation. Pump bearings splash lubrication by the N46 mechanical oil, the original bearing seal type is gap seal. Due to the pump running for a long time, bearing damage caused by seal gap increases or damage, causing a large number of oil leakage, not only caused by the waste of oil, but also affect the operation of the pump. Replace the seal on the bearing gland required
