The high-vacuum discharge pump is a two-stage pump developed and produced for the distillation industry. It is suitable for use in high-temperature cycling and high-temperature vacuum discharging processes under high temperature and high vacuum conditions in distillation equipment. Under high-temperature conditions, how can the service life of high-vacuum discharge pumps be extended? The editor provides the following analysis: 1. When high-vacuum discharge pumps operate in high temperatures, hinge supports should be installed on the piping during installation in a cold state, to prevent the piping from shifting as the temperature rises. 2. The coupling must be aligned thermally after the pump body has warmed up, in order to avoid additional torque being generated during operation. 3. Startup should be carried out slowly to prevent a sudden increase in pressure ahead and behind, thereby avoiding damage to the bearings or mechanical seals. 4. When starting the pump, do not increase the speed recklessly when no pressure has been established at the outlet, in order to prevent premature damage to the shaft or bearings. 5. When cleaning the pipette, do not use a pump to deliver the cleaning solution; instead, remove the internal components and reinstall them after the cleaning is complete, to prevent foreign objects from entering the pump. 6. The temperature of the jacket of the vacuum discharge gear pump can be slightly lower than the temperature of the heating medium in the upstream and downstream jackets. By reducing the temperature in the bearing area, the **load-bearing capacity of the bearings can be increased. 7. Conduct regular inspections of vulnerable components such as gears, bearings, and machine seals. If wear is detected, it should be replaced promptly, which can extend the pump’s operational life. 8. The filter of the vacuum discharge pump should be removed, cleaned, and replaced regularly; it should not be operated under high pressure or at the upper pressure limit for extended periods.
