Problems solved by technology

When the booster pump works continuously, the sliding vane or the sliding valve ring on the eccentric wheel that slides close to the inner wall of the stator at a high speed of 300-3000r / min will inevitably wear out, resulting in the diffusion of molecular components with high saturated vapor pressure in the oil. Into the vacuum space, it will not only affect the ultimate vacuum of the booster pump, but also flow back and diffuse to the vacuum system, pollute the vacuum system, and directly affect the ultimate vacuum acquisition
As the wear of the contact surface between the rotor, sliding vane and the inner wall of the stator increases, the surface roughness of the friction pair also increases, the surface temperature increases, the internal friction with the oil molecules increases, and the temperature of the oil increases, resulting in colloids in the oil Adhering to the friction surface, the oil will deteriorate due to heat, and even slightly pyrolyzed to generate low-molecular compounds to pollute the vacuum system, resulting in reduced efficiency of the booster pump, increased energy consumption, increased failure rate, and reduced service life
