How Much Do You Know About Car Urea Pump？

The environmental pollution brought on by vehicle exhaust has actually seriously affected the planet, and the development of the urea pump has actually excellently enhanced the environmental pollution brought on by exhaust discharges. The vital part for controlling diesel exhaust emissions is the urea pump controller, which has been extensively utilized in established nations such as Europe. If you intend to buy SCR urea pump controller, you need to understand more detailed info on it.

​

The urea pump is a vital part of the urea option injection metering system. Its major function is to extract the urea remedy in the urea container, preserve a certain pressure, and after that supply it to the injection device to meet the circulation as well as stress requirements of the injection metering system.

The Relationship Between Urea Pump As Well As SCR

The urea pump is the core part of the SCR system, and its performance is carefully related to the engine's discharge feature. In order to ensure that the working dependability of the urea pump satisfies the working demands of the SCR system, the urea pump requires to be adjusted.

After using SCR innovation, the engine's emission feature depends to a huge extent on the calibration of the urea shot system as well as the loved one efficiency of the urea pump. Based on the basic concept of nitrogen and also oxygen decrease, the SCR gadget uses a 32.5% urea aqueous remedy as a decreasing agent, and under the catalysis of the catalyst surface area coating, the NOX in the exhaust gas is minimized to N2 as well as H2O.

The exhaust temperature level of diesel motor is typically 200-500 ° C, which primarily fulfills the task needs of the vanadium-based driver used in SCR. Consequently, the NOX in the exhaust gas sent out by the diesel motor promptly reacts with the urea liquid solution to produce nitrogen and water.

Urea Pump Function

Its working concept is to make use of urea service and NOX oxidation-reduction response to produce N2, which is non-toxic to human body, as well as discharge it into the environment. The urea pump pumps the urea solution out of the urea storage tank and delivers the urea service to the nozzle with the sharing pipeline.

Functioning Principle

When providing liquid to the urea injection system, the electric motor drives the supply pump to provide the urea service from the urea container to the stress chamber. A part of the urea option is made use of for injection and a component is returned to the urea tank with the orifice.

In a reduced temperature setting, in order to protect against pipeline clog, the pump needs to empty the pressure chamber # The controller automatically judges that it enters the empty state. Right now, the supply pump quits working, and the on-off shutoff is opened at the same time. The urea service is drawn back into the urea tank.

Everybody wants to stay in even more eco-friendly city, it is wise to buy SCR urea pump controller can make life better.



The urea pump pumps the urea service out of the urea storage tank as well as delivers the urea option to the nozzle through the sharing pipe.

The hydraulic as well as mechanical concept of the urea pump is revealed in the figure, which is mostly composed of a motor, a supply pump, a reverse pump, an on-off valve, a pressure chamber, as well as an orifice. When supplying fluid to the urea injection system, the motor drives the supply pump to supply the urea solution from the urea storage tank to the stress chamber. A part of the urea option is made use of for injection as well as a part is returned to the urea container through the orifice.
