1. The Roots vacuum pump often checks the position of the oil level.If it does not meet the requirements, it must be adjusted to meet the operating requirements.The oil level standard shall prevail.

2. The oil change period depends on the actual use and can meet the user 's performance requirements and other considerations. Generally, the new Roots pump pumps clean gas. It is recommended that the ferrous metal powder cannot be seen after the oil is changed for about 100 hours. The oil may be extended after the deadline.

3. Always check the quality of the oil.You should find out that the oil has deteriorated in time and replace it with new oil to ensure that the Roots vacuum pump works normally.

4. Check after 2000 hours of work, check the aging degree of the rubber seal, check whether the exhaust valve is cracked, clean the valve plate and exhaust valve seat to clean the entire Roots pump cavity components, such as rotor, rotor, Springs, etc.Generally use gasoline to clean and dry.When cleaning and assembling, it should be handled lightly and carefully scratched.

5. Vacuum pump bearing lubricating oil to the bearing body.Observe that the oil level should be at the center of the oil.Replace or add lubricating oil in time.

6. Check for looseness in the pipes and joints.Observe whether the Roots vacuum pump is flexible.

7. After the trial operation, it should be reassembled.Generally, the oil should be changed twice for 2 hours.Since the Roots vacuum pump will have a certain amount of volatile content, it can be operated normally, and then put into normal work. So how to use the Roots vacuum unit correctly, in the actual use process, we have to do the following:

1.1 Operators must be familiar with Zibo Tongpu Vacuum 's product manuals.

1.2 Before using the product, make sure that there are no factors caused by environmental factors caused by long - term storage of the product.

1.3 If abnormal sounds and vibrations are found during work, the machine should be shut down

for investigation.

1.4 The shell of electrical equipment must be grounded or connected to zero.

2. Preparation before starting

2.1 Check whether the water level of the water pump(fore - stage pump) reaches more than 3 / 4 of the water tank, and make up

if it is insufficient.

2.2 Check whether the water used in the water tank is clean, and it is not allowed to use sewage containing mud and sand, so as not to block the pipeline, increase the load of the motor and cause failures, affecting the service life of the water flushing pump.

2.3 Check the lubricating oil surface height of the intermediate pump and the main pump body, must be more than 3 / 4 of the oil window, and also check the color of the lubricating oil.If there are many milky white or black impurities, notify the mechanic to replace the lubricating oil.

2.4 Check whether the circulating cooling water channel of the intermediate pump and main pump is intact, open the circulating cooling water inlet and outlet valves, and check whether the circulating cooling water inlet and outlet are normal.

2.5 Check whether the drain valve of the buffer tank at the bottom of the intermediate pump is closed.

2.6 Check the vacuum pump unit circuit is intact and the control cabinet instructions are normal.

2.7 Check whether the starting pressure of the intermediate pump and the main pump of the electrode contact pressure gauge of the vacuum pump unit is normal.
