What should be paid attention to when using roots vacuum unit?

Now our industries are some modern industries, and pump products are an indispensable part of some enterprises. There are many kinds of pump products, and their functions are relatively comprehensive. Roots vacuum pump unit is a widely used equipment in industry. Next, let me introduce the misunderstandings that should be paid attention to when using roots vacuum pump unit.

1. The roots vacuum unit must be equipped with a front stage pump, and the roots pump cannot be used alone.
2. When selecting roots vacuum unit, we should pay attention to the sealing mode of vulnerable parts of roots pump. The mode of mechanical sealing can effectively improve the working efficiency of roots pump. If the sealing mode of roots pump is shaft sleeve sealing, the working efficiency will be greatly reduced. We need to pay special attention when selecting roots pump.
3. Roots vacuum machine is mostly used in Roots vacuum unit. Its function is to improve the pumping speed and the vacuum degree of the front stage pump. The roots pump shall be equipped with bypass valve in the configuration connected with the front stage pump, which can effectively protect the roots pump. If the pumping of the front stage pump is unstable or other factors lead to abnormal operation of the whole unit, the roots pump with bypass valve will protect the roots pump at this time, so as to prolong the service life of the whole vacuum unit.
4. If the vacuum degree of Roots vacuum pump is reduced during use, it is necessary to check whether the clearance between roots pump rotors has changed. If the rotor clearance of roots pump becomes larger, the roots pump needs to be replaced, because this kind of Roots vacuum machine does not make static and dynamic balance for Roots pump rotors during production and processing, Or it is sealed with shaft sleeve.
