How Much Do You Find Out About Auto Urea Pump as well as The Connection In Between Urea Pump And SCR

The environmental pollution caused by auto exhaust has seriously affected the earth, as well as the development of the urea pump has actually outstandingly boosted the environmental pollution triggered by exhaust discharges. The essential component for controlling diesel exhaust emissions is the urea pump controller, which has been commonly made use of in established nations such as Europe. You require to know even more comprehensive info on it if you want to buy SCR urea pump controller.


The urea pump is a fundamental part of the urea solution injection metering system. Its major function is to draw out the urea service in the urea storage tank, preserve a particular pressure, and afterwards supply it to the shot unit to satisfy the circulation and also pressure requirements of the injection metering system.

The Connection In Between Urea Pump And SCR

The urea pump is the core element of the SCR system, and its efficiency is carefully pertaining to the engine's emission feature. In order to make sure that the working reliability of the urea pump satisfies the working requirements of the SCR system, the urea pump requires to be adjusted.

After making use of SCR modern technology, the engine's exhaust function depends to a large extent on the calibration of the urea shot system as well as the relative efficiency of the urea pump. Based on the basic concept of nitrogen and also oxygen reduction, the SCR tool utilizes a 32.5% urea aqueous service as a lowering representative, as well as under the catalysis of the driver surface area finishing, the NOX in the exhaust gas is minimized to N2 as well as WATER.

The exhaust temperature of diesel motor is generally 200-500 ° C, which primarily fulfills the activity needs of the vanadium-based catalyst made use of in SCR. Consequently, the NOX in the exhaust gas discharged by the diesel engine rapidly responds with the urea aqueous option to create nitrogen and also water.



Urea Pump Function
Its functioning concept is to utilize urea option and also NOX oxidation-reduction reaction to generate N2, which is non-toxic to human body, as well as release it into the ambience. The urea pump pumps the urea remedy out of the urea container and also transfers the urea remedy to the nozzle through the sharing pipeline.


Functioning Principle

The mechanical as well as hydraulic concept of the urea pump is shown in the figure, which is mainly made up of an electric motor, a supply pump, a reverse pump, an on-off shutoff, a pressure chamber, and also an orifice. The pump has 2 functioning states, supply and vacant. When providing liquid to the urea shot system, the motor drives the supply pump to deliver the urea option from the urea storage tank to the stress chamber. A part of the urea service is utilized for injection as well as a part is returned to the urea container with the orifice.

In a reduced temperature setting, in order to prevent pipeline obstruction, the pump requires to clear the stress chamber # The controller immediately judges that it goes into the empty state. Currently, the supply pump quits working, and also the on-off shutoff is opened at the same time. The urea solution is drawn back right into the urea tank.




The urea pump pumps the urea remedy out of the urea container and transfers the urea option to the nozzle via the conveying pipeline.

The hydraulic and also mechanical principle of the urea pump is shown in the figure, which is primarily made up of a motor, a supply pump, a reverse pump, an on-off shutoff, a stress chamber, as well as an orifice.
