There are two reasons why the vacuum pump has oil injection:


1. The problem of the vacuum pump itself, such as the blockage of the oil circuit, causes the oil filtered by the filter element to not return to the fuel tank in time, but accumulates in the exhaust port. When the vacuum pump pumps the atmosphere, the oil accumulated in the exhaust port will be blow out.


2. The problem of vacuum pump filter element, good quality vacuum pump filter element has the characteristics of fast oil discharge, oil droplets grow fast, and it is easy to drip down under the action of gravity. For a filter element with poor quality, the separated small oil droplets are often adsorbed on the cotton on the surface of the filter element, and a row of atmosphere is blown out of the exhaust port to form oil injection.


Therefore, to prevent the vacuum pump from injecting oil, it is necessary to carry out regular maintenance of the vacuum pump. In addition, the vacuum pump filter produced by the regular manufacturer should be used, with guaranteed quality and fast drainage capacity.
