How Much Do You Learn About Vehicle Urea Pump?

The environmental pollution brought on by vehicle exhaust has actually seriously impacted the earth, and also the creation of the urea pump has actually excellently improved the environmental pollution brought on by exhaust emissions. The vital element for regulating diesel exhaust discharges is the urea pump controller, which has actually been extensively used in developed countries such as Europe. If you intend to buy SCR urea pump controller, you need to understand more detailed information on it.

The urea pump is an important part of the urea solution shot metering system. Its major function is to extract the urea service in the urea storage tank, preserve a particular stress, and after that deliver it to the shot unit to meet the flow and also pressure needs of the shot 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 pertaining to the engine's discharge feature. In order to make sure that the functioning dependability of the urea pump meets the working needs of the SCR system, the urea pump needs to be adjusted.

After using SCR technology, the engine's discharge feature depends to a large extent on the calibration of the urea shot system and the family member performance of the urea pump. Based upon the standard concept of nitrogen and also oxygen reduction, the SCR tool utilizes a 32.5% urea aqueous remedy as a reducing agent, as well as under the catalysis of the driver surface area covering, the NOX in the exhaust gas is reduced to N2 and also WATER.

The exhaust temperature level of diesel motor is usually 200-500 ° C, which basically meets the activity demands of the vanadium-based catalyst used in SCR. Consequently, the NOX in the exhaust gas given off by the diesel engine promptly responds with the urea liquid remedy to create nitrogen and water.

Urea Pump Feature
Its working concept is to make use of urea remedy and NOX oxidation-reduction reaction to create N2, which is non-toxic to human body, and release it into the atmosphere. The urea pump pumps the urea service out of the urea container and also transports the urea service to the nozzle through the sharing pipeline.

The hydraulic and mechanical principle of the urea pump is shown in the figure, which is mostly composed of a motor, a supply pump, a reverse pump, an on-off shutoff, a stress chamber, as well as an orifice. The pump has 2 working states, supply as well as empty. When supplying liquid to the urea shot system, the electric motor drives the supply pump to supply the urea solution from the urea storage tank to the pressure chamber. A part of the urea remedy is utilized for injection as well as a component is gone back to the urea tank with the orifice.

In a reduced temperature setting, in order to stop pipeline clog, the pump requires to clear the stress chamber # The controller instantly judges that it goes into the empty state. At this time, the supply pump quits working, and also the on-off shutoff is opened at the same time. The urea remedy is withdrawed into the urea container.




The urea pump pumps the urea remedy out of the urea container and delivers the urea solution to the nozzle with the communicating pipe.


Every person wishes to live in more eco-friendly city, it is smart to buy SCR urea pump controller can make life far better.
