The performance of a vacuum pump is generally tested through factors such as ultimate vacuum, pumping speed/discharge volume, pressure testing, noise level, and after-sales service.
1. Pumping Speed Performance: A vacuum pump has a certain pumping speed performance, capable of removing gas in a short time.
2. Cryogenic Performance: For some representative cryogenic gases such as helium and hydrogen, a high pumping speed performance is required.
3. Sealing Performance: Good sealing performance is essential to ensure the normal operation of the vacuum pump.
4. Corrosion Resistance: Vacuum pumps will be exposed to gases during long-term operation, so good corrosion resistance is necessary.
5. Noise Control: Vacuum pumps generate noise during operation, so noise control is required.
