What is the cause of noise in vacuum pumps for woodworking engraving machines?
First check whether there is high pressure blower in debris, such as, open the shell, internal cleaning; secondly, check the impeller is stuck, it is best to contact the high pressure blower factory repair, re assembly to eliminate the fault. Third check the bearings for damage and replace the bearings if necessary.
Hello, I'm the sales and maintenance of imported vacuum pump you said this could be what causes the bearing seal vacuum pump operating at high temperature burnt out vacuum pump like woodworking engraving machine is no use to produce much more wood oil pump vacuum pump inside the filter clogging caused by change of bearing seal and recommended vacuum pump inside the filter and regularly bearing oil seal (often to maintain the oil pump which has a built-in like open end cover as disposable toothpaste point inside the hotel use.)
Vacuum pump in the case of noise increases, there should be other conditions, such as: motor heating, vacuum changes, and so on. Motor bearings may be lack of oil, impeller damage and other reasons. You'd better check it out and turn on the vacuum pump to see the reason.
