Anti-clogging tips for sewage lifting pumps
The anti-clogging skills of sewage lifting pumps mainly include the following aspects:
1. Precautions before installation
Reasonable selection:
Choose the appropriate sewage lifting pump model and specifications according to actual needs to ensure that the pump's processing capacity matches the actual drainage volume.
For media containing a large amount of fiber or solid impurities, consider using a cutting type or non-clogging sewage lifting pump.
Add a filter device:
Install a filter device at the entrance of the sewage lifting pump, such as a filter screen, a grille, etc., to prevent fine debris from entering the pump cavity and reduce the risk of clogging.
2. Daily use and maintenance
Regular cleaning:
Regularly clean the sewage lifting pump, including the pump body, impeller, filter screen and other components, remove accumulated dirt and impurities, and keep the pump clean.
When cleaning, you can use clean water or appropriate solvents, and choose the appropriate cleaning method according to the composition of the medium.
Inspection and maintenance:
Regularly check the operating status of the sewage lifting pump, including the wear of components such as motors, bearings, and seals, and replace damaged or aging components in time.
Regularly check the wearing parts in the pump body, such as worm gears, impellers, etc., to ensure that they are in good condition.
Dilute the viscosity of the medium: For media with high viscosity, try to dilute it as much as possible to reduce the adsorption of the medium in the pipeline and pump body and reduce the risk of blockage. Use automatic cleaning device: Choose a sewage lift pump with an automatic backwashing device, which can automatically clean the inside of the pump regularly, effectively prevent the accumulation of impurities, and reduce the occurrence of blockage. 3. Special situation handling Use oil-water separator: For sewage containing a lot of grease, an oil-water separator can be used to separate the grease, and only the water without grease is sent to the sewage lift pump to reduce the impact of oil pollution on the pump and the risk of blockage. Dealing with severe blockage: If the sewage lift pump is severely blocked, you can first try to flush it with clean water or solvent. If it doesn't work, you need to dismantle the pump to clear it. Pay attention to safety when dismantling the pump, cut off the power supply and follow the correct disassembly and assembly steps to avoid damage to the pump body or other parts. 4. Long-term shutdown and maintenance Empty the medium in the pump: If the sewage lift pump needs to be shut down for a long time, the medium in the pump body should be emptied to prevent the medium from drying up or scaling in the pump body, affecting the performance of the pump. Anti-corrosion treatment: For easily corrosive parts, such as pump body, impeller, etc., anti-corrosion treatment can be carried out to extend their service life. Proper storage: The sewage lifting pump and its accessories should be properly stored to avoid moisture, damage or loss.
