Application of hydraulic high-pressure water pump in seawater desalination equipment-COMPANY NEWS-Medium pump fluid

Hydraulic high-pressure water pump is an important component of seawater desalination equipment, especially in reverse osmosis seawater desalination systems. The main function of this pump is to apply sufficient pressure to the feed seawater so that water molecules can separate from high salinity seawater through a semi permeable membrane and form fresh water.

working principle

In a reverse osmosis seawater desalination system, the function of a high-pressure pump is to pressurize seawater beyond its natural osmotic pressure, so that the water can be forced to pass through a semi permeable membrane, while the salt fraction is blocked on the other side of the membrane. This process is called reverse osmosis because it is opposite to the phenomenon of permeation in nature, where water naturally flows from low salinity to high salinity.

Technical features

Hydraulic high-pressure water pumps typically have the following characteristics:

1. Structural design: Most high-pressure pumps adopt a horizontal axial suction, single shell, guide vane segmented foot supported multi-stage centrifugal pump structural design, which makes the pump have high stability and reliability.

2. Scope of application: These pumps are suitable for seawater desalination systems ranging from 1000 to 10000 tons/day, with flow rates ranging from 100 to 600 cubic meters/hour and head between 500 and 900 meters.

3. Technical and economic indicators: These pumps have advanced technical and economic indicators, which can replace imported products and achieve localization. They have stable operation, low vibration, low noise, long service life, long overhaul period, and fast and convenient maintenance.

4. Material selection: Due to the corrosive nature of seawater, these pumps are typically made of stainless steel to ensure long-term durability and reduce maintenance costs.

Application examples

For example, the high-pressure pump (APP) and its accessories provided by Danfoss Reverse Osmosis Division have a flow range from 0.15 to 31 cubic meters per hour and can be used in systems that produce up to 7500 cubic meters of water per day. In addition, there are high-pressure pumps specifically designed for seawater desalination equipment, such as the GYB model high-pressure pump produced by Zhengzhou Guangyuan Cleaning Equipment Co., Ltd., which is suitable for pipeline pressure testing and seawater desalination applications.

In summary, hydraulic high-pressure water pumps play a crucial role in seawater desalination equipment, and their high efficiency and durability are essential for the successful implementation of seawater desalination projects.
