Selection and configuration of submersible sewage pumps
The selection and configuration of submersible sewage pumps need to comprehensively consider sewage characteristics, usage requirements, motor power, material selection, and control systems. Through reasonable selection and configuration, it can be ensured that the submersible sewage pump can operate efficiently and stably in actual use.
1. Selection of submersible sewage pumps
1. Model selection:
Submersible sewage pumps mainly transport media containing solid particles, fibers and other sewage. Therefore, when selecting, its corrosion resistance should be considered and it can adapt to various sewage media.
Commonly used submersible sewage pump series include WQ series, ZB-YJ series, ZB-G series, ZSB-F series, etc.
WQ series is a single-suction two-stage centrifugal type, suitable for the discharge and transportation of sewage and wastewater.
QDX/QX series is suitable for indoor and outdoor courtyard drainage and irrigation, as well as industrial and farmland drainage and irrigation.
QS series is suitable for household, agricultural water, industry and municipal engineering.
2. Selection according to sewage characteristics:
Select the pump model according to the size of the impurity particle diameter in the sewage to be discharged. Different impurities have an impact on the service life of the equipment.
Select the appropriate pump model and specification parameters according to the required discharge volume to meet actual needs.
3. Power selection:
Determine the power size of the selected product according to actual needs, and consider the relationship between the head and the required power value.
You can first calculate the head required, and then calculate the required power value through the formula.
2. Configuration of submersible sewage pump
1. Motor configuration:
Select high-temperature resistant motors (such as H-class insulation) to ensure that the motor runs stably in a high-temperature environment.
The quality of the motor must be guaranteed, and choose products from well-known brands to avoid frequent failures in the later stage due to the use of miscellaneous products.
2. Cable and seal configuration:
Use high-temperature resistant cables to ensure that the cables are not easy to age or break at high temperatures.
The mechanical seal should use carbide dock to tungsten carbide mechanical seals to ensure that the pump can run continuously.
3. Material selection:
The overall 304 or 316 stainless steel (including the internal impeller and main shaft) can be customized to enhance the corrosion resistance of the pump.
Stainless steel materials also have the characteristics of rust and corrosion resistance, which can extend the service life of the pump.
4. Control system configuration:
Equipped with water level automatic control system, it can automatically control the start and stop of the pump without special supervision.
Equipped with electronic control equipment, it can automatically monitor the leakage, phase loss, overload, and array pressure start of the pump.
5. Installation and accessories:
Compact structure, easy to move, simple installation, no need to build a pump room, reducing project cost.
Can be used with automatic coupling device to make installation and maintenance faster and more convenient.
