The RO water pump adopts a vertical installation method, occupying a small area. The center of gravity of the pump coincides with the center of the pump foot, ensuring smooth operation, low vibration, long service life, compact overall structure, and easy installation and maintenance. Segmented combination, usually a vertical multi-stage multi segment structure, with screws clamping the inlet section, middle section, and outlet section into one, and each stage is equipped with an impeller and a guide vane. Impeller and guide vanes. Impeller generally adopts a single-stage or multi-stage structure, and the material is mostly stainless steel or high-strength engineering plastic. Guide vanes can form an appropriate flow velocity distribution for the liquid before entering the volute, reducing cavitation phenomenon.
RO water pumps mainly work based on the principle of centrifugal force. After being powered on, the motor drives the impeller to rotate at high speed, causing the water at the center of the impeller to be thrown towards the edge of the impeller under the action of centrifugal force, forming a low-pressure zone. The water at the inlet is continuously replenished to the center of the impeller under the pressure difference, and the water thrown towards the edge obtains kinetic energy and pressure energy. It is transported to the reverse osmosis membrane module at a high pressure and flow rate, providing sufficient inlet pressure for the reverse osmosis system, allowing water to pass through the reverse osmosis membrane under pressure and achieve separation of water and impurities.
The shaft seal adopts mechanical seals, such as silicon carbide, hard alloy and other materials, which are reliable, leak free and have small mechanical losses. The bearings mostly use imported NSK/SKF maintenance free bearings, which have high stability and can withstand large axial forces. The motor drives the impeller on the shaft to rotate at high speed. Under the action of centrifugal force, the liquid filled in the impeller is thrown from the center of the impeller along the flow channel between the blades towards the periphery of the impeller. The liquid pressure and velocity increase simultaneously, and it is guided to the next stage impeller through the guide shell flow channel, gradually flowing through all the blades and guide shells, increasing the energy of the liquid pressure and obtaining a certain head. Performance characteristics: Efficient and energy-saving: Adopting excellent hydraulic models and advanced manufacturing processes, different flow rates and head requirements can be met by changing the pump stages. Stable and reliable operation: The structural design is reasonable, and the centrifugal force generated by the high-speed rotation of the impeller is large, ensuring smooth operation. It is also equipped with an intelligent protector to effectively protect the pump from dry running, phase loss, overload, etc.
It can transport thin, clean, non flammable and explosive media that do not contain solid particles or fibers, such as mineral water, softened water, pure water, etc. It can also pump mildly corrosive media.
