Knowledge of Roots vacuum pump rotor

After long-term use of Roots vacuum pump, due to the wear of the Roots vacuum pump rotor, the sealing performance will be reduced, which will greatly reduce the pumping capacity and vacuum. However, many users do not know the reason. Roots vacuum pump suppliers will introduce solutions for you.

Dirty or hard solid particles enter the Roots pump and collide with the rotor for a long time, causing damage to the rotor; in addition to the above reasons, the normal wear of the rotating blades is also a very important reason. When the oil is emulsified in the vacuum pump, the wear of the rotating blades will increase; How to repair the worn rotor and improve the vacuum? If the processing capacity allows, the rotor can be replaced after wear, because it is more convenient to replace the rotor than to grind the end face of the pump cavity.

If the rotating blades of the vacuum pump are severely worn, first correct the rotating blades according to the measured size of the rotating blades. You can use a fine file to wrap the gauze paper, flatten it, and grind the edge to measure the size and square until you can't see the transparent gap. If the rotor of the Roots vacuum pump is worn too much, go to the grinder first, and then scrape the two ends of the rotor and the pump cavity according to the selected clearance value to ensure the matching clearance.

Preparations before the operation of Roots vacuum pump

The pump isRoots vacuum pumpThe main pump of the equipment, the water ring pump is a series front pump. The water ring pump is selected as the front pump of the Roots vacuum pump, which has more advantages than other vacuum pumps. It can not only overcome the pressure difference of a single water ring pump, but also keep the Roots pump working quickly. What regular operations should the Roots vacuum pump do before operation?

1. Always check that the oil level position of the Roots vacuum pump does not meet the requirements and needs to be adjusted to meet the requirements. When the vacuum pump is running, the oil level is based on the center of the oil level standard, and the mechanical parts are lubricated after the oil is in place.

2. The oil change period of the Roots water ring vacuum unit should be considered according to the actual use and whether it can meet the performance requirements of the pump.

3. Under normal circumstances, the vacuum pump should be overhauled after 2000 hours of work, check the aging degree of the rubber seal and the exhaust valve plate for cracks, and clean the dirt deposited on the valve plate and the exhaust valve seat, and clean the entire cavity Parts such as rotors, pump bodies, gears and bearings.

5. Add bearing lubricating oil to the bearing body, observe that the oil level should be in the oil mark, and replace or supplement the lubricating oil in time.

6. Check whether the pipes and joints of the vacuum pump are loose, and turn the vacuum device by hand to see if it is flexible.

7. After reassembly, it is necessary to carry out a trial operation. Generally, idle for 2 hours and change the oil twice. Because the vacuum pump will have a certain amount of volatiles during the cleaning process, it can only be put into normal operation after normal operation.

8. Start the motor. After the Roots vacuum pump is running normally, open the outlet pressure gauge and inlet, gradually open the gate valve, and check the motor load according to the appropriate pressure.

It should be controlled as much as possible.Roots vacuum pump, Make the flow and head of the vacuum pump within the range indicated by the sign to ensure that the vacuum pump runs at a high efficiency point and achieves a good energy saving effect.

This is the end of the explanation. Let's see you next time.
