Help for cause of broken water ring vacuum pump impeller
Thread Content
Dear masters, please help me analyze. This vacuum pump impeller is damaged like this. What are the most likely reasons? Did something foreign get in?" I think even if there is a foreign object, it cannot be crushed like this? Is it possible that the material is not up to par? Thank you again in advance for your help.
First, check how many years it has been used, and then check whether there are any problems with operation and whether there is water inside.
Whether the equipment itself conforms to the working conditions, whether the operation conforms to the design, whether the design conforms to the actual situation, operating conditions (inspection records, service life), etc.
The impeller was so broken that it was unimaginable. . . Analyze from several aspects: 1. Material reasons, unreasonable design, causing cracks at a certain temperature 2. 2.1 Operation reasons, insufficient flow, leading to cavitation, many pits in the impeller, reduced strength and fragmentation 2.2 There are debris stuck in the impeller, the question is, did your compressor trip and stop due to high current? Can the poster explain what happened clearly?
Is the impeller made of resin? Yes, this is normal……

It's so awesome. We've had it for eleven years and it's running normally.
It can also be considered an operational issue. When the water ring pump is started, the cavity cannot be filled with working fluid, otherwise the impeller or shaft will be damaged. This can also be avoided by adding an overflow line when piping the pump and strengthening operating procedures.
Under cavitation, the strength of the impeller decreases, the brittleness increases, and the low water level causes the impeller to overheat. Two phenomena lead to
