The cleaning methods of water pumps mainly include the following:
Mechanical cleaning method: Use a scraper or a rotary wire brush to remove hard scale and sediment. For severe scaling and blockage, you can use a drill to dredge the pipe, or use a sponge ball cleaning method to remove scale by rubbing the sponge ball against the pipe wall.
Acid pickling method: Use hydrochloric acid as a cleaning agent to remove scale by soaking or circulation. The acid pickling method requires the addition of corrosion inhibitors to reduce corrosion to the metal. The soaking method is simple but slow, while the circulation method is more effective but more expensive by forcing the acid to circulate.
High-pressure water flushing method: Suitable for removing scale on the outer wall of the pipe, especially for pump pipes with severe coking. Fine quartz sand can be added to the water to improve the cleaning effect.
Daily maintenance and comprehensive overhaul: Including checking the amount of lubricating oil, maintaining shaft seals, anti-rust coating, etc. Regularly clean the scale in the impeller and flow channel to ensure the efficient operation of the water pump. In addition, perform a comprehensive overhaul at least once a year to check key components such as impellers, seals and bearings.
These methods can effectively keep the water pump clean and running efficiently, extending its service life.
