Permanent magnet variable frequency vacuum pump is a kind of screw vacuum pump driven by permanent magnet motor, and the speed of motor is controlled by frequency converter, so as to realize the accurate adjustment of vacuum degree and pumping volume. It combines the high efficiency of permanent magnet motor and the flexibility of variable frequency speed regulation, and can automatically adjust the operating state according to the actual working conditions to achieve the purpose of energy saving and efficient operation.

How it works？

1. Screw compression principle: The core component of permanent magnet variable frequency vacuum pump is the screw rotor. Through the rotation of the screw, the gas is inhaled and compressed, and finally discharged. The mesh and rotation of the screw rotor make the gas gradually compressed in the compression chamber, forming a vacuum environment.
2. Permanent magnet motor drive: The permanent magnet motor uses high-performance permanent magnet materials, with high efficiency, high power density and low energy consumption characteristics. The motor drives the screw rotor directly, eliminating the need for additional gearing and reducing energy loss.
3. Frequency conversion speed control: The speed of the motor is controlled by the frequency converter, and the operating frequency is automatically adjusted according to the actual needs (such as vacuum degree and pumping volume). This intelligent regulation optimizes energy consumption while ensuring that the equipment is operating under optimal conditions.

Advantages Compared with traditional vacuum pumps：
1. Energy saving effect: Compared with traditional Roots vacuum pump or ordinary screw vacuum pump, the energy consumption of permanent magnet variable frequency vacuum pump can be reduced by 30%-50%.
2. Maintenance costs: The oil-free design reduces the frequency of lubricating oil changes and reduces maintenance costs.
3. Operation efficiency: By variable frequency speed regulation, the device can adjust its operating status according to actual requirements, avoiding unnecessary energy consumption.
Environmental performance: Oil-free design reduces oil pollution and is more environmentally friendly.

Selection precautions
1. Vacuum requirement: Select the appropriate vacuum range according to the actual application (such as 1000Pa to 10^-3 Pa).
2. Pumping capacity: Select the appropriate pumping capacity (such as hourly pumping capacity) according to the process requirements.
3. Operating environment: Consider the operating environment of the device, such as temperature, humidity, and dust conditions.
4. Control functions: Select devices with intelligent control functions to achieve a higher level of automation.
