Screw vacuum pumps are widely used in industries such as metallurgy, chemical engineering, food, and electronic coating. In addition to mastering the correct operating methods, it is also important to do a good job in daily maintenance during use. Today, the editor will introduce the maintenance methods of screw vacuum pumps to you.

1. If conditions permit, the pipeline should be cleaned to ensure unobstructed flow.

2. After reassembly, a trial run should be conducted, generally requiring 2 hours of idle operation and a second oil change. This is because there may be a certain amount of volatile substances left in the screw vacuum pump during cleaning. After normal operation, it can be put back into normal work.

3. Check whether there is any looseness in the pipeline and joint of the screw vacuum pump. Rotate the vacuum pump by hand to see if it is flexible.

4. Regularly check the wear of the shaft sleeve, and replace it in a timely manner when there is significant wear on the shaft sleeve.

5. Start the motor, when the screw vacuum pump is running normally, open the outlet pressure gauge and inlet vacuum pump, and gradually open the gate valve according to the appropriate pressure displayed. At the same time, check the load condition of the motor.

6. When the screw vacuum pump needs to be stopped, first close the gate valve and pressure gauge, and then stop the motor.

7. Check the oil level position. If it does not meet the requirements, adjust it to meet the requirements. The oil level should be at the center of the oil gauge when the vacuum pump is running.

8. Check the oil quality of the vacuum pump, and replace it with new oil in a timely manner if oil deterioration is found to ensure the normal operation of the screw vacuum pump.

The above is the maintenance of screw vacuum pumps, hoping to be helpful to everyone. In addition, during use, it is important to pay attention to controlling the temperature and humidity of the environment.
