The Classifications and Working Principles of RO Booster Pump

RO pump is also known as RO booster pump, RO diaphragm pump, reverse osmosis booster pump, and is a type of DC diaphragm booster pump. It is currently one of the core parts of the water purification industry and household water purifiers.


Ⅰ. Definition of RO booster pump


RO booster pump is the booster pump used in reverse osmosis equipment. It has the functions of self-priming and pressurization, and is one of the key and important components of the RO water purifier. The RO booster pump is another important component of the RO membrane in the RO water purifier, which provides the water pressure and water flow required for its work, so as to achieve the purpose of the RO water purifier to produce pure water.


Ⅱ. The classification of RO booster pumps


1. According to RO membrane water production specifications, it can be classified into two categories. The first type is household type. The corresponding pumps of the "national standard RO membrane" have 50 gallons, 75 gallons, and 100 gallons, which are also called household RO booster pumps. The other type is the pump corresponding to the "non-standard commercial large flow RO membrane", including 150 gallons, 200 gallons, 300 gallons, 400 gallons, etc., also known as RO booster pumps for business machines. Generally, commercial machines are equipped with better accessories. So if you are going to buy the best RO booster pump, the key is to figure out its configuration.


2. Classified according to the environment of use, it can be divided into ordinary RO booster pumps and 0-pressure RO booster pumps for municipal water pressure zones. The 0-pressure RO booster pump is mainly used in rural areas and other areas with no water pressure and low water pressure. It is also called a 0-pressure pump (or self-priming pump).


3. Classified by function, the market mainly includes: ordinary RO booster pumps, RO stabilized pumps with stable water pressure, RO water cut-off pumps with the function of automatic water cutoff and replacement of the water inlet solenoid valve in the RO water purifier system.


Ⅲ. The working principles of RO booster pump


The RO booster pump uses a DC motor as a power drive device. After the power is turned on, the motor rotor rotates, driving the eccentric swing wheel to perform eccentric motion, and then transforms it into a three-cam water scaffold assembly closely connected with the eccentric swing wheel to reciprocate, driving the diaphragm to perform reciprocating motion at the same time, and produce a reciprocating motion on the valve cover. Reciprocating suction and squeezing phenomenon.


When the cam water kicking bracket assembly moves from top to bottom, the booster chamber produces a vacuum effect. Under the action of vacuum suction, the water inlet one-way valve is opened and water is sucked into the booster chamber. When the motor rotates to a certain angle, the cam water kicking bracket assembly gradually changes from the original top-down movement to the bottom-up movement, squeezing the sucked water upwards. Under the action of squeeze pressure, the water inlet one-way valve is positively sealed, and the water can only be discharged in the direction of the high-pressure chamber. When the pressure is greater than the reaction force of the water outlet one-way valve, the water outlet one-way valve is opened and the water is discharged to the high-pressure chamber.


The continuous rotation of the motor makes the diaphragm of the RO booster pump continue to reciprocate, completing the purpose of pumping and boosting water.
