Common Faults And Solutions of Submersible Sewage Pumps

A submersible sewage pump is a device that completely submerges the pump body into water for operation, with a small footprint, easy installation, and low noise during operation. It is mainly used for treating urban sewage, factory drainage, and sewage treatment plant sewage transportation, and can effectively treat sewage containing solid substances and fibers to prevent blockage. Its corrosion-resistant materials and efficient design make it outstanding in various complex wastewater treatment scenarios, widely used in municipal engineering, industrial wastewater treatment, and construction drainage fields.

1. Pump casing leakage

   ①. Reason: Poor sealing of pump casing, unqualified quality, connection bolts too tight or too loose, etc.

   ②. Solution: Check if the pump casing and sealing gasket are damaged, and replace the damaged parts; Adjust the tightness of the connecting bolts to ensure sealing.

2. Excessive pump body noise

   ①. Reason: The pump seat is not securely installed, the impeller is unbalanced, the bearings are damaged, and the head is too high.

   ②. Solution: Adjust the pump seat, rebalance the impeller, replace bearings, reduce head, etc.

3. Motor overheating

   ①. Reasons: Motor winding overload, excessive speed, blocked water inlet, poor cooling water circuit, etc.

   ②. Solution: Reduce load, reset operating parameters, clean water inlet, restore smooth cooling water circuit, etc.

   4.Pump blockage

   ①. Reason: Pipeline blockage, excessive accumulation of polymer in the pump, lack of filter screen at the inlet, etc.

   ②. Solution: unclog pipelines, clean accumulated materials, install filters, etc.

   5.Pump unable to start

   ①. Cause: Power failure, electromagnetic starter damage, motor damage, etc.

   ②. Solution: Check if the power supply is normal, replace the electromagnetic starter or motor, etc.

Maintaining and maintaining sewage pumps is not difficult. As long as faults are detected and resolved in a timely manner, the service life of the equipment can be extended, ensuring stable operation. At the same time, it is also recommended to regularly maintain the equipment, such as replacing lubricating oil, inspecting motor windings, cleaning filters, etc.

【 Conclusion 】

As an important sewage treatment equipment, sewage pumps require users to pay attention to their maintenance and upkeep during use. When encountering problems, it is necessary to promptly investigate and solve them to ensure the normal operation of the pump.
