Roots vacuum pump is a kind of pump caused by two "8-shaped" relative rotating rotors, which causes volume change to produce vacuum, so it is also called positive displacement pump. During operation, it is necessary to have a continuous contact line at the point where the rotor of the pump is required to engage, so as to prevent gas from flowing back from the vent to the vacuum pump. Therefore, it is necessary to check the engagement of the two rotors frequently during operation. With the extension of construction time, the impeller has been worn for a long time, and restricted by the directional rotation, forming the non-uniformity of meshing space between the two impellers, and even collision, making the impeller appear a circular and solitary external depression.
1. It is necessary to install roots vacuum pump in a dry, well ventilated and clean place.
2. The ambient temperature of Roots vacuum pump is 5-40 ° C.
3. Roots vacuum pump has necessary horizontal device, and there should be enough space around for daily inspection and maintenance, so it is easy to install and disassemble.
4. After connecting the power supply, the direction of the motor shall be as shown by the direction arrow on the pump.
5. It is necessary to clean the pipes connecting the pumping vessel. There should be no impurities and other foreign matters, the diameter of the hole should not be less than the diameter of the pump port, and the length should be short to ensure that it has enough conductivity, and the pipe connection is necessary to seal.
6. It is necessary for the gas to be pumped to be free of solid particles entering the pump room.
Therefore, the two impeller rotors are worn in different degrees in terms of outer diameter and length, and the gap between the impeller rotor and the shell is also increased. Therefore, the vacuum degree of Roots vacuum pump is reduced, and the time is large and small. It is necessary to adjust and adjust the clearance between the impeller and the clearance between the end cover and the pump housing in time.
