High temperatures can significantly reduce the viscosity of the vacuum pump oil, which affects the vacuum level of your equipment; high temperatures also tend to harden the cooled vacuum pump oil
Too close, due to the existence of the rotor vane groove and the head of the rotor vane only a narrow band contact, the rotor vane turned to the cut point position when the sealing effect is not good
The working principle of rotary vane vacuum pump is: the front and rear stage rotors with rotary vane are installed eccentrically in the cylindrical front and rear stage cylinders.
