Oil free screw vacuum pump equipment is an emerging vacuum pump machine with advantages such as high efficiency, reliability, and environmental protection. The process principle is to compress the gas through the joint action of the rotor and stator, so that the gas forms a vacuum at the outlet of the pump, thereby achieving the purpose of vacuuming. Oil free screw vacuum pump equipment can be widely used in industries such as food, medicine, chemical, and semiconductor.
Oil free screw vacuum pump is mainly composed of rotor, stator, centrifugal force balancing device, bearings, etc. Among them, the rotor is the main component of the pump, and the stator is responsible for fixing the rotor. The centrifugal force balancing device is mainly used to balance the centrifugal force generated by the rotor during high-speed rotation, while the bearings are used to support the rotor of the pump. The entire pump has a compact structure, small volume, and light weight, making it easy to install and maintain.
The working principle of an oil-free screw vacuum pump is to rotate two screws together, compressing the gas during rotation and thus forming a vacuum. The specific work steps are as follows:
After the pump is started, the rotor begins to rotate.
2. The gas is gradually compressed under the joint action of the rotor and stator.
When the gas is compressed to the outlet of the pump, it is discharged to the outside and forms a vacuum.
Throughout the entire process, the centrifugal force balancing device plays a role in balancing the rotor, ensuring the stable operation of the pump.
