Dry screw vacuum pump is a common vacuum equipment used in vacuum systems in various industries. Before the official launch, we need to carry out a series of inspection work to ensure that the equipment is smooth and reliable during operation. The following is a dry screw vacuum pump needs to be checked before starting. 

First, the opening of the air inlet and outlet

Before starting, check whether the opening of the air inlet and outlet is normal. If the inlet and outlet are not opened correctly, the inlet and outlet of the pump will not be smooth, which will affect the vacuum degree of the entire system and the efficiency of the pump.

Second, the mechanical state of the pump

The mechanical state of the pump needs to be checked to ensure that the internal rotating parts of the pump are normal, the bearing is in good working condition, and will not produce vibration or abnormal noise when starting, to ensure that the performance of the pump is good.

Third, pump interface and pipeline status

Before starting, it is also necessary to check the interface and pipeline status of the pump. This inspection includes checking whether the pump interfaces and lines are well sealed, whether the joints are loose or blocked, and if there is a problem, it needs to be cleaned or repaired.

4. Power connection

For dry screw vacuum pumps, the power connection is also very important. You need to check whether the power cable is properly connected. When checking the cable connection, ensure that the cable is firmly connected and in good contact to avoid short circuit or fault.

In short, the inspection work before starting the dry screw vacuum pump not only helps to protect the equipment, but also helps to improve the efficiency and performance of the equipment. Through the careful implementation of these checks, the probability of problems can be reduced, the service life of the equipment can be extended, and the user can be more assured.
