2BV liquid ring vacuum pump is composed of pump cover, pump body, disc, impeller, mechanical seal, motor and other parts. If we want to use the equipment better, we should have some knowledge about the maintenance of its parts. In order to make you use the equipment better, let's introduce the maintenance knowledge of 2BV liquid ring vacuum pump:
1. In order to avoid wearing the impeller, pump body or jamming the impeller, the dust particles entering the pump cavity with gas and working fluid can be washed away through the flushing port at the bottom of 2BV liquid ring vacuum pump.
2. If hard water is used as working fluid, it shall be softened or the pump shall be cleaned with solution within a certain period.
3. The normal working bearing of 2BV liquid ring vacuum pump motor is 15 ℃～ 20 ℃ higher than the surrounding temperature, and it is not allowed to exceed 55 ℃～ 60 ℃. The normal working bearing shall be filled with oil 1-2 times a year, cleaned at least once a year, and all lubricating oil shall be replaced.
4. In case of leakage of the mechanical seal adopted by the 2BV liquid ring vacuum pump, check whether the dynamic and static rings of the mechanical seal have been damaged, or the seal ring has aged. If the above situation occurs, new parts shall be replaced.
