Influence of shaft power variation on the performance of imported vacuum pump
- Feb 27, 2017 -

Imported vacuum pump shaft power on the vacuum is also a certain impact, the general increase in shaft power are associated with the phenomenon of system vacuum drop. The main reasons are:

① diaphragm broken;

② packing pressure is too large;

③ import check valve failure. If the pump uses a single-piece one-way valve, when the valve plug does not catch up or seal surface scaling, corrosion and sealing is not strict, it will occur string gas phenomenon, that is, from the import of imported vacuum pump inlet air into the work Pump, so that pump power increases, the system vacuum drop.
