Screw pump daily maintenance

As one of the key equipment in industrial production, the daily maintenance of screw pump plays a vital role in ensuring the normal operation of the equipment and extending its service life. Maintenance work mainly includes lubrication maintenance, sealing maintenance, cleaning maintenance, repair maintenance and other aspects.

First, lubrication maintenance

Lubrication maintenance of screw pump is the key to ensure its stable operation. Under normal circumstances, the use of mineral oil or synthetic oil as a lubricant to adapt to high temperature, high pressure and other harsh conditions, while the performance of ordinary lubricants will be greatly affected. In daily maintenance, it is necessary to check the lubrication system of the screw pump regularly to ensure that the oil quality and oil quantity meet the requirements. If abnormal conditions such as black oil color and increased moisture are found, the lubricating oil should be replaced in time.

Two, sealing maintenance

The sealing part of the screw pump needs to be checked and maintained frequently. Long-term use, the sealing part of the pump may have wear, aging and other problems. If the seal is not tight, it may cause the pump to leak oil or water, affecting the normal use. Therefore, in the daily maintenance, it is necessary to carefully check the sealing condition, if it is found that the seal is not tight or the seal is aging and damaged, it needs to be replaced in time. At the same time, the seals are lubricated regularly to extend their service life.

Third, cleaning and maintenance

In the process of use, the screw pump will inevitably be affected by impurities such as oil, dust, sand and so on. Long-term accumulation of these impurities may lead to a decline in pump performance and even affect its normal operation. Therefore, in daily maintenance, cleaning work is particularly important. When cleaning, the appropriate cleaning agent or solvent should be selected to clean each part of the pump one by one, while ensuring that the selected cleaning liquid has no corrosion effect on the pump material.

Fourth, repair and maintenance

In addition, after using the screw pump for a period of time, regular maintenance is required to ensure the normal operation of the pump. During the maintenance process, the various components of the pump, such as bearings and shaft seals, should be carefully checked. Check whether the bending degree is normal, and perform necessary replacement and maintenance. At the same time, it is also necessary to record the operation of the pump in order to know its operating status at any time.

Fifth. Other maintenance

In addition to the above basic maintenance work, other maintenance work is also required. For example, replace the filter element or screen of the pump regularly to ensure that the pump inlet is not affected by impurities; Perform motor maintenance, such as measuring motor parameters, cleaning motor housing, etc.

In summary, the daily maintenance and maintenance work of the screw pump is crucial, including cleaning, overhaul and other maintenance work. Do these work to ensure the normal operation of the screw pump, can extend the service life of the screw pump.
