Vacuum pump oil

Additives in vacuum pumps are also gradually consumed in the use of failure, resulting in functional decline, the occurrence of harmful components of equipment, known as aging or degradation, aging and degradation to a certain extent after the damage to the equipment is greater than its good effect, it is necessary to replace new oil.

Generally speaking, the degradation of vacuum pump oil is a reaction process dominated by hydrocarbon oxidation, which is followed by sound field aldehydes, ketones, alcohols to organic oxyacids. Each reaction is accompanied by varying degrees of differentiation and polymerization. The central product is hydrocarbon peroxides, which are highly active and unstable compounds, and are easy to break into metals and form special compounds. Other wear and faults, high-level vacuum pump oil is rich in highly effective antioxidant additives, can delay the degradation of vacuum pump oil or reduce the degradation of products to the damage of vacuum pump.oil_diffusion_pump

Generally speaking, the connotation of vacuum pump oil will change when it rotates at high temperature and high speed for a long time. For example, the vacuum pump oil emits the same water as stinky gutter after it has been used for a certain time, 80% of which is due to emulsification. If the material is sticky, then it is carbonized.
