There are three reasons:
1. the problem of the vacuum pump itself, such as the blockage of the oil circuit, resulting in the oil filtered out of the cartridge can not return to the oil tank in time, but gathered in the exhaust port, when the vacuum pump pumps the atmosphere, these oil gathered in the exhaust port will be blown out.
2. the problem of vacuum pump cartridge, good quality vacuum pump cartridge has the characteristics of fast oil discharge, the oil droplets grow fast, and it is easy to drop down under the effect of gravity. Poor quality cartridge, separated from the small oil droplets are often adsorbed on the surface of the cartridge cotton, a row of the atmosphere, it is blown out of the exhaust port, the formation of oil spraying.
3. too much oil, you can pour out some of the oil.
Therefore, to prevent the vacuum pump oil spraying should be done on the vacuum pump for regular maintenance, in addition to the use of branded vacuum pump filters, quality assurance, drainage capacity fast.
