Information

The manufacturer of Vacuum pump rotor tells you that the two rotors of the vacuum pump are relatively synchronously operated through a pair of high-precision gears. The driving shaft is connected with the motor through a coupling. The vacuum pump rotor manufacturer tells you that there are two main types of transmission structure layout: One is that the motor and gear are placed on the same side of the rotor. The manufacturer of Vacuum pump rotor tells you that the driven rotor is directly driven by the gear at the motor end, so that the torsional deformation of the driving rotor shaft is small, and the gap between the two rotors will not change due to the large torsional deformation of the driving shaft, so the rotor The gap between them is uniform during operation. The biggest disadvantages of this transmission method are:

customized Vacuum pump rotor for house
1. There are three bearings on the driving shaft, which increase the difficulty of pump processing and assembly, and it is inconvenient to disassemble and adjust gears;
2. The overall structure is uneven, and the center of gravity of the pump is biased to the side of the motor and gear box.
Features:
1. The vacuum pump rotor manufacturer tells you that there is a 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. There are gaps between the rotors and between the rotor and the shell, no lubrication is required, and the friction loss is small, which can greatly reduce the driving power and achieve a higher speed;
3. There is no need for oil sealing and lubrication in the pump cavity, which can reduce the pollution of oil vapor to the vacuum system;
4. There is no compression in the pump cavity and no exhaust valve. The structure is simple and compact, and it is not sensitive to dust and water vapor in the exhausted gas;
5. The vacuum pump rotor manufacturer tells you that the compression is relatively low and the hydrogen pumping effect is poor;
6. The vacuum pump rotor manufacturer tells you that the surface of the rotor is a curved cylinder with a more complicated shape, which is difficult to process and inspect.
