A vacuum pump is a device that generates, improves and maintains a vacuum in an enclosed space by various methods. A vacuum pump can be defined as a device or equipment that uses mechanical, physic...
Many vacuum process installations are equipped with a Roots pump on top of the pre-stage pump, both to increase the pumping speed and to improve the vacuum. However, the following problems are ofte...
The molecular pump is a vacuum pump that uses a high-speed rotor to transfer momentum to the gas molecules so that they gain directional velocity and are thus compressed, driven towards the exhaust...
This series of Roots-type vacuum pumps cannot be used alone. It needs to be used in series with the pre-stage vacuum pump to increase the pumping rate of the pre-stage vacuum pump when the pressure...
1. The number of fan blades is small, and the air volume generated is small.
2. The fan speed is low, the wind pressure and air volume are small.
3. The motor has high power and high current, r...
