Vacuum pump selection issues
Thread Content
I have a project in progress: the suction inlet of the main pump is at a height of about 5000 mm above the liquid surface. The diameter of the inlet pipe is 80 mm, and its length is approximately 10 m. I want to use a vacuum pump to evacuate the gas from the inlet pipe and the main pump chamber first, so that the medium can be introduced into the pump chamber. After that, the vacuum pump will be turned off and the main pump started. Which type of vacuum pump should be used for this purpose? I’m not familiar with vacuum pumps, and the information available online is a bit confusing. I hope experts can give me some guidance! Thank you! ! !
It is best to choose a water ring pump (to prevent the medium from entering the pump and damaging the vacuum pump), as well as a buffer tank in front of the water ring pump.
It’s similar to a vacuum water lift system; a water ring pump or a steam ejector can both be used.
Used for vacuum water lift; steam ejectors and water ejectors can be used, with water ejectors being the recommended choice due to their low cost, simplicity of use, and ease of operation.
The vacuum suction for the water pump, right? Generally, a liquid ring vacuum pump is chosen. Just be careful during the process not to let the vacuum pump draw water into its chamber – that’s all.
Water ring vacuum pumps are preferred, but the water intake system needs to be designed as a separate subsystem for interlocking purposes; no other pumps are as practical for this process as these ones
