Discharge volume and absolute pressure of dry vacuum pumps
Thread Content
Dry vacuum pumps – the devices available on the market today – have very good specifications regarding their exhaust volume and absolute pressure values. But in practical applications, it fails to reach the level it claims to achieve, that’s what everyone thinks. Some even fall short of the performance level of water ring pumps with the same displacement.
When selecting equipment, it is advisable to choose reliable brands, and the performance testing process should be witnessed before the equipment leaves the factory
If it doesn’t meet the standards and you still accept it, there may be **. They are traitors. If someone else is the one who received it and it has nothing to do with you, don’t blame the equipment for being poor. The market is highly competitive these days, with fake products mixed in with genuine ones. For such issues, there’s only one solution: use it temporarily, and if the requirements are met then make the payment; otherwise, just replace it.
This device has been in use for 15 years, and the impeller needs to be replaced more and more frequently.
After a device has been in use for a certain period, it is necessary to assess whether it still has value for repair; generally, the lifespan of such devices is around 10 years
What are the advantages of dry vacuum pumps compared to water ring vacuum pumps?
Oh, with such a frequent replacement of the impeller, is there also a possibility that the casing could get excessively worn? It should be replaced entirely. It is recommended to replace it with the original equipment.
The two are not comparable, and it also depends on the operating conditions for selection.
