The vacuum pump for extrusion manufacturer tells you that the two rotors of the vacuum pump are operated relatively synchronously through a pair of high-precision gears. The driving shaft is connected with the motor through a coupling. There are two main types of transmission structure layout: one is that the motor and the gear are placed on the same side of the rotor as shown in the figure. The vacuum pump for extrusion manufacturer tells you that the driven rotor is directly driven by the motor end gear, so that the torsional deformation of the driving rotor shaft is small, and the gap between the two rotors will not be changed due to the large torsional deformation of the driving shaft. The gap between the rotors is uniform during operation. The following will take you to understand the characteristics of the vacuum pump.

Features of vacuum pump:
1. Larger pumping speed in a wider pressure range;
2. The rotor has good geometric symmetry, so the vibration is small and the operation is stable. The vacuum pump for extrusion manufacturer tells you that there are gaps between the rotors and between the rotors and the casing, no lubrication is required, and the friction loss is small, which can greatly reduce the driving power, so that a higher speed can be achieved;
3. The pump cavity does not need to be sealed and lubricated with oil, which can reduce the pollution of oil vapor to the vacuum system;
4. There is no compression in the pump chamber and no exhaust valve. Simple and compact structure, insensitive to dust and water vapor in the pumped gas;
5. The compression ratio is low, and the effect of hydrogen pumping is poor;
6. The surface of the rotor is a curved cylinder with a complex shape, which is difficult to process and inspect.
The above are the characteristics of vacuum pumps that vacuum pump for extrusion manufacturers take you to understand, I hope to help you.
