Application of water pumps in environmental protection field
Water pumps are widely used in the field of environmental protection, and they play a key role in many environmental protection-related systems. Here are some specific application examples:
1. Sewage treatment and discharge
Sewage strong self-priming pump group:
Composition: The sewage strong self-priming pump group consists of motor, pump body, impeller, mechanical seal and other components.
Features: It has the characteristics of strong self-priming ability, good anti-clogging performance and easy installation. There is a cutting device in the pump body, which can tear and shred long fibers, bags, belts, grass, cloth strips and other materials to prevent clogging. In addition, the pump body also adopts a shaft seal-free design to avoid leakage problems.
Application: It is widely used in municipal sewage treatment, industrial wastewater treatment, domestic sewage treatment in hospitals and hotels, etc. It is especially suitable for places with strict requirements on vibration and noise, such as key engineering projects, pump rooms, central air-conditioning systems, and scientific research institutions and hospitals.
Sewage lifting pump:
Function: It is used to pump sewage from low to high, ensure the flow and pressure of sewage discharge, and reduce the burden on urban drainage systems.
Application: It plays an important role in scenes such as basement drainage, drainage of toilets or tea rooms in high-rise buildings.
2. Green Energy System
Double-suction self-priming pump:
Features: Double-suction self-priming pump is a centrifugal pump with double suction ports, which has excellent self-priming ability and efficient liquid conveying ability.
Application:
Wind power generation system: used for liquid conveying in cooling system and lubrication system, such as conveying coolant and lubricating oil, to ensure the stable operation of the fan.
Solar photovoltaic power generation system: used for liquid conveying in hot water system, to ensure the rapid transmission of hot water and improve the overall efficiency of the system.
Biomass energy system: due to its excellent self-priming and solid particle conveying ability, it is widely used in biomass gasification and power generation system to convey the liquid part of biomass raw materials.
Geothermal energy system: with its high temperature resistance and corrosion resistance, it performs well in geothermal energy system, can stably convey hot water, and effectively handle liquid containing solid particles.
3. Seawater desalination
Seawater desalination high-pressure pump:
Function: Seawater desalination high-pressure pump is the core power equipment of seawater desalination system, providing the necessary high pressure for the reverse osmosis membrane seawater desalination process. Through the action of the high-pressure pump, the seawater is pressurized to exceed its osmotic pressure, thereby driving the freshwater molecules in the seawater through the reverse osmosis membrane to achieve the desalination process.
Features: Usually has a higher working pressure, such as some models with a pressure of up to 140bar (about 14MPa), which can meet the high pressure demand in the desalination process. At the same time, the efficiency of the pump directly affects the energy consumption index of the entire desalination system.
Materials: Made of corrosion-resistant materials, such as nickel-aluminum bronze, etc., to adapt to the working environment of seawater, a highly corrosive medium.
Application: In large and medium-sized seawater desalination devices, multi-stage centrifugal pumps are a common choice, with the advantages of compact structure and easy maintenance; while in small and medium-sized seawater desalination devices, plunger pumps are widely used due to their stable flow and adjustable pressure.
