Judgment method of screw vacuum pump

Dry screw vacuum pump is a new type of vacuum pump, which is developed to replace the traditional water ring vacuum pump, oil ring vacuum pump and other pump types. Because of its unique design principle, it can be oil-free and water-free, and can be used as corrosion-resistant coating. The excellent sealing design will far exceed the performance of traditional vacuum pump in any aspect.

How to judge whether the dry screw vacuum pump is qualified can be judged from the following aspects:

1. Limit vacuum degree: of course, the lower the limit vacuum, the better. At present, the domestic one is about 5pa, while the imported one is about 1pA.

2. Vibration and noise: vibration must be small, noise must be less than 80 dB.

3. If it is used in a corrosive environment, it is better to ask the manufacturer for a sample of the same coating, and put it in the factory for a test. If the coating or coating ratio used by each manufacturer is different, its performance will be greatly different.

4. Sealing: This is also very important, but we can only learn from the manufacturer's instructions. The most direct way is to determine whether there is leakage through the medium after connecting to the system.
