Product Description
Adblue Urea Pump for benz
As an important means of controlling diesel engine exhaust emissions, it has been widely used in Europe and other developed countries, and has played a significant role in improving the environmental pollution caused by exhaust emissions. After using SCR technology, the emission function of the engine largely depends on the calibration of the urea injection system and the related performance of the urea pump. According to the basic principle of nitrogen and oxygen reduction, SCR device uses 32.5% aqueous urea solution as reducing agent to reduce NOx in waste gas into N2 and H2O under the catalysis of catalyst surface coating. [1]
The exhaust temperature of diesel engine is generally 200-500 ℃, which basically meets the activity requirements of vanadium based catalyst used in SCR. Therefore, NOx in the tail gas emitted by diesel engine quickly reacts with urea aqueous solution to produce nitrogen and water.
Urea pump is the core component of SCR system. Its performance is closely related to the emission function of engine. In order to ensure that the working reliability of urea pump meets the working requirements of SCR system, it is necessary to calibrate the urea pump.

When the urea pump works, the urea first filters out impurities through the filter element to prevent blocking the pipeline and nozzle, and then enters the urea solution pump, which is fully mixed with compressed air and ejected together. After the urea pump stops injection, the compressed air will be blown back for a period of time to blow the residual urea back into the tank to prevent urea crystallization from blocking the pipeline. The urea sensor converts the liquid level signal into resistance signal, which can be intuitively displayed on the instrument panel after passing through the control unit
Urea pump is an important part of the urea solution injection metering system. Its main function is to extract the urea solution in the urea tank, maintain a certain pressure, and then deliver it to the injection unit to meet the flow and pressure requirements of the injection metering system
