Types and selection of drainage pumps
There are various types of drainage pumps, each with its own specific application scenarios and advantages. The following are the types of drainage pumps and their selection recommendations:
I. Types of drainage pumps
1. Permanent magnet flood control pump
Features: small size and light weight, can be directly hung on simple floating bodies, such as lifebuoys, vehicle tires, etc., suitable for reservoirs, lakes, seawater lifting and other environments.
Example: The weight of conventional models is about 30KG~35KG, which is one-fifteenth of the weight of traditional water pumps under the same flow head.
2. Mobile pump truck
Features: It can be regarded as a small movable pump station with high flexibility, which can be quickly towed to the application site according to needs.
Application: Suitable for solving current emergency water supply and drainage needs.
3. Centrifugal pump
Features: simple structure, easy maintenance, stable operation, it is the preferred pump type for urban drainage pump stations.
Principle: Use centrifugal force to suck liquid into the pump body from the inlet, and then accelerate the liquid through the rotation of the rotor, and finally discharge it from the outlet.
4. Submersible pump
Features: Suitable for deep wells, rivers, reservoirs and other environments, with small footprint and low noise.
Application: Municipal drainage, industrial sewage discharge, agricultural channel drainage, etc.
5. Self-priming pump
Features: It can suck liquid from itself and drain it without additional water diversion.
Application: Places with large location restrictions or long-term continuous drainage.
6. Diesel flood control pump
Power source: Use diesel engine, flexible and risk-resistant.
Electric flood control pump
Power source: Use electric motor, stable operation and low noise.
7. High-pressure flood control pump
Features: Suitable for long-distance transportation of large-flow water, long transportation distance and corrosion resistance.
2. Selection of drainage pump
1. Choose according to the application scenario:
For municipal drainage, industrial sewage discharge and other occasions, you can choose a submersible pump or a centrifugal pump.
For places with large location restrictions or long-term continuous drainage, you can choose a self-priming pump.
For emergency water supply and drainage needs, you can choose a mobile pump truck.
2. Choose according to the power source:
For places with high mobility requirements and strong risk resistance, diesel flood control pumps can be selected.
For places with good power supply conditions and high noise requirements, electric flood control pumps can be selected.
3. Choose according to performance parameters:
Determine the flow, head, power and other parameters of the pump according to actual needs to ensure that the pump can meet actual needs.
4. Consider maintenance and cost:
Choose a pump type with simple structure and easy maintenance to reduce maintenance costs.
Choose a suitable pump type according to the budget to ensure economic benefits.
