Diesel engine fire pump units have become an indispensable and important equipment in fire protection systems with their strong power, wide range of flow and head, stable and reliable performance, highly automated control system, efficient and energy-saving operation characteristics, convenient and fast installation and maintenance methods, wide adaptability and high cost performance.

The flow range of centrifugal pumps is usually large, and the flow adjustment methods are flexible and diverse, which is suitable for large flow and high head occasions; while the flow range of positive displacement pumps is relatively small, and the flow stability is better, which is suitable for small flow and occasions that require precise flow control.

Common mechanical sealing materials for stainless steel pumps include metal materials, PTFE, fluorinated rubber and special ceramics. Choosing suitable sealing materials is of great significance to ensure the normal operation of the pump and extend its service life.

Through regular inspection, cleaning, lubrication, replacement, electrical inspection, packing and sealing, adjustment and calibration, and special environmental treatment, the sewage pump can be effectively maintained to keep it running efficiently and stably.

Choosing a suitable sewage pump requires comprehensive consideration of multiple factors, including demand, flow, head, pump type, material, power, and maintenance and care. Through careful analysis and comparison, you can choose the sewage pump that best suits your needs.

When a sewage pump is contaminated, a series of remedial measures need to be taken to restore its normal function and extend its service life.

Preventing sewage pumps from being contaminated by water requires comprehensive consideration of aspects such as selecting the right pump, regular cleaning and maintenance, increasing fluid velocity, intelligent monitoring and maintenance, and environmental management and safety measures. Through the comprehensive application of these measures, the risk of sewage pumps being contaminated by water can be effectively reduced, ensuring the normal operation of the sewage treatment system.

Common faults of submersible sewage pumps, such as starting problems, pump failure, heating bearing damage and insufficient flow, can be solved by checking and adjusting the corresponding parts. At the same time, regular maintenance of submersible sewage pumps, inspection and replacement of wearing parts can also effectively prevent the occurrence of faults.

The technical parameters of submersible sewage pumps include flow, head, power, speed and diameter, etc. The selection and determination of these parameters need to be comprehensively considered according to the specific usage scenarios and needs to ensure that the performance and use effect of the pump are optimal.

Submersible sewage pumps are mainly composed of motors, pump bodies, impellers, volutes, sealing devices, etc. These parts work together to achieve the function of pumping sewage from low places to high places or long-distance transportation.
