Desulfuration pump is widely used in pump products, but if you want to extend the service life of desulfuration pump, you should remember the daily protection. In order to ensure the safe operation and long service life of the desulfurization pump, attention must be paid to the daily protection. The protection and maintenance shall pay attention to the following aspects:
1. Shaft seal protection:
The sealing water pressure and water volume of the packing shaft seal pump shall be inspected regularly. A small amount of clean water shall always flow along the shaft. The packing gland shall be adjusted regularly, and the packing shall be inspected and replaced regularly. The water pressure of the shaft seal and the water volume of the shaft seal shall meet the above requirements.
2. Adjustment of impeller:
In order to ensure the efficient operation of the pump, it is necessary to adjust the clearance between the impeller and the front guard plate in time. When adjusting the clearance between the impeller, stop the pump first, loosen the bolts that compress the bearing box, loosen the adjusting nuts, and move the bearing assembly forward. At the same time, use the hand rolling shaft to twist it according to the rolling direction of the pump until the impeller and the front guard plate are abraded. Then use the adjusting bolts to move the rotor backward, and record the moving room before and after The clearance shall be evenly distributed between the front and rear guard plates of the impeller until the clearance between the impeller, the front guard plate and the rear guard plate is equal, and the two dust discs shall be tightly adjusted and fastened on the shaft. After adjustment, before starting again, it is necessary to check whether the impeller rolling is normal, whether the bearing assembly pressing bolts are tightened, and then restart the pump.
3. Bearing lubrication:
When the bearing assembly is in the device, if the device is correct, the lubricating oil is appropriate, the maintenance is timely, and the transportation life will be long, the maintenance personnel shall regularly inspect the bearing assembly, search for the bearing and lubricating oil, and regularly increase or replace the lubricating oil during the operation, cut off the time, the injected amount and the rotation speed of the pump, the bearing specification, the time of continuous events, the shutdown and opening times of the pump, the surrounding conditions and the transportation Many factors, such as line temperature, are related to the need to gradually accumulate accumulation history and add lubricating oil reasonably and timely.
4. The spare pump shall roll the shaft 1 / 4 turn every week to make the bearing bear the static load and external vibration evenly.
