German Leclere Variable Frequency Oil Screw Vacuum Pump VTL750

Germany's JoyVariable frequency oil screw vacuum pumpVTL750The working process can be divided into three stages: suction, compression, and exhaust. When the rotor rotates, each pair of teeth that mesh with each other completes the same working cycle again. Now, a pair of teeth are used to illustrate. Compression process: The end face is the exhaust end face. Here, the male rotor rotates clockwise and the female rotor rotates counterclockwise. The upper end of the rotor in the figure is the suction section, and the lower end is the exhaust end.Efficient frequency conversion and energy saving By adjusting the frequency of the frequency converter and changing the motor speed, the air end speed can be driven to change, and the gas production can be achieved30-100%The wide range adjustment between them fully adapts to the gas needs of users under different working conditions, can meet different air demands, improve gas efficiency, and save energy consumption. Can achieve smooth adjustment, avoid frequent motor start stop caused by demand changes, protect the motor, and extend the service life of the unit

Structure of Variable Frequency Oil Screw Vacuum Pump：

The structure in terms of sealing and lubrication is roughly similar to other vacuum pumps, with the difference being that the variable frequency oil screw vacuum pump is fixed with an exhaust pipe, which is connected to the cavity of the main variable frequency oil screw vacuum pump, and the pipeline is connected to the oil and gas separation above the oil position. The exhaust end of a regular vacuum pump uses a mechanical seal, while the intake end usually uses a lip shaped seal.

Germany's JoyVariable frequency oil screw vacuum pumpVTL750Inhalation process：The male rotor rotates counterclockwise, while the internal thread rotates clockwise. The upper end of the rotor is the suction section, and the lower end is the exhaust section. Exhaust process: In the exhaust process of the variable frequency oil screw vacuum pump, the exhaust process begins after the volume between the teeth is connected to the exhaust port. As the interdental volume decreases, gas with exhaust pressure gradually exits through the exhaust port.
