Roots rotary vane vacuum pump unit operation

The first very important process of using roots rotary vane vacuum pump unit is the preparation before starting. Check all parts, check whether the cooling circuit of roots pump is smooth, and check the exhaust valve to ensure that it is in the open state. Pay attention to check to ensure that the oil level of each pump is on the oil level line. If it is below the oil level line, it is required to add oil. If it exceeds the oil level line, it should be drained. Check whether the rotation direction of the motor is the same as that of the arrow on the pump. If the use of equipment is suspended for a long time, are the parts rolling sensitive when starting up again? If it can't roll, it is necessary to roll several revolutions by manpower. It is absolutely forbidden to start it by force with the motor, which will cause serious damage to the pump. 

The second process is to pay attention to the problems when starting. Before starting, the cooling water valve of roots pump should be opened, and the front stage pump of rotary vane vacuum pump should be started to open the inlet valve of front stage pump together. Open the air inlet valve of the front and rear stage, and turn on the air valve smoothly. During the working process of the equipment, if the temperature of some parts is too high, there may be irregular noise, or other abnormal phenomena. The roots rotary vacuum unit should stop checking immediately.

The third operation is to stop the problem that the device needs to pay attention to. Before stopping, the inlet valve should be closed first, and the vent valve of roots pump should be opened. Then the equipment will stop actively. Close the inlet valve of the front stage pump and stop the front stage pump together. The valve of the cooling water device is closed. If the operation is stopped for a long time, the roots rotor vacuum unit should drain all the water in the cooling water jacket in the cold zone, otherwise, the water in the sleeve will swell and cause damage due to freezing.

Finally, repair and maintenance, roots rotary vacuum unit should adhere to the environment around the equipment clean and boring. Always check the smoothness of each part. If there is a lack of smooth oil, it should be made up in time. When the lubricating oil is polluted, clean lubricating oil should be replaced in time. After replacement, the bolts should be tightened from the beginning to ensure the sealing environment. When disassembling and repairing, all parts must not be struck by external force. Pay special attention to the smooth and smooth sealing surface, otherwise it will cause air leakage after re installation.
