The vacuum pump oil is lubricating oil specially developed for vacuum equipment, and the vacuum pump plays an important role in scientific research, medical treatment, aerospace, solar energy, chips and other industries. However, with the continuous development of the industry, the vacuum pump oil prepared by directly blending the base oil with the conventional vacuum pump oil has the following disadvantages in the actual use process:
firstly, in order to break through the technical bottleneck of products in the high-tech fields of scientific research, chips, solar energy and the like, the limit pressure of a vacuum pump is required to be smaller and smaller, and the vacuum pump oil of the traditional blending process formula cannot obtain the corresponding limit pressure due to the distillation range problem of the base oil, even can cause the production failure of some high-end products, thereby causing economic loss.
Thirdly, as the load of the vacuum pump is continuously increased, the working temperature of the vacuum pump is correspondingly increased, and part of the working temperature is increased to 120 ℃ from the traditional 80 ℃, the oxidation of the oil of the vacuum pump is aggravated due to the increase of the working temperature, the oil sludge carbon is easily formed, even the vacuum pump is blocked, a manufacturer has to shut down and overhaul, and great economic loss is caused. The vacuum pump inevitably sucks water in the air during operation, and other harmful gas substances in a production field, and if the harmful gas substances cannot be processed in time, the failure of the vacuum pump oil is aggravated.
