Original inventory of Laibao vacuum pump SV300B

Original inventory of Laibao vacuum pump SV300B(referred to as rotary vane pump) is a type of oil sealed mechanical vacuum pump. The working pressure range of Laibao vacuum pump SV300B is 101325~1.33 × 10-2 (Pa), which belongs to low vacuum pump. The Laibao vacuum pump SV300B can be used alone or as a pre pump for other high vacuum pumps or ultra-high vacuum pumps. The Laibao vacuum pump SV300B has been widely used in metallurgy, machineryElectronic, chemical, light industry, petroleum, and pharmaceutical production and research departments.
Rotary vane pumps can remove dry gases from sealed containers, and if equipped with gas ballast devices, they can also remove a certain amount of condensable gases. But the Leybold vacuum pump SV300B is not suitable for removing gases with high oxygen content, corrosive to metals, chemical reactions to pump oil, and particles and dust.

Original inventory of Laibao vacuum pump SV300BThe relationship between pumping speed and inlet pressure is specified as follows: at inlet pressures of 1333Pa, 1.33Pa, and 1.33 × 10-1 (Pa), the pumping speed values shall not be lower than 95%, 50%, and 20% of the nominal pumping speed of the pump, respectively.
The rotary vane pump is mainly composed of pump body, rotor, rotary vane, end cover, spring, etc. Install a rotor eccentrically in the cavity of the rotary vane pump, with the outer circle of the rotor tangent to the surface inside the pump cavity (with a small gap between the two), and two spring equipped rotary vanes installed in the rotor slot. When rotating, the top of the rotor is kept in contact with the inner wall of the pump chamber by centrifugal force and spring tension, and the rotor rotates to drive the rotor to slide along the inner wall of the pump chamber.

The main features of the SOGEVAC series pumps include a complete range of product specifications, multiple vacuum degrees to choose from, excellent materials, and high standard production processes to ensure the reliability and durability of the pumps, making them suitable for a wide range of industrial fields.
