How Much Do You Learn About Car Urea Pump?

The environmental pollution triggered by car exhaust has seriously impacted the earth, and also the creation of the urea pump has excellently boosted the environmental pollution triggered by exhaust emissions. The essential component for regulating diesel exhaust emissions is the urea pump controller, which has been extensively utilized in developed nations such as Europe. If you wish to buy SCR urea pump controller, you require to know even more thorough information on it.

The urea pump is an important part of the urea solution injection metering system. Its primary feature is to extract the urea service in the urea tank, maintain a certain stress, and then provide it to the shot device to meet the circulation as well as stress requirements of the shot metering system.

The Connection In Between Urea Pump And SCR

The urea pump is the core component of the SCR system, and its efficiency is carefully pertaining to the engine's discharge function. In order to ensure that the functioning integrity of the urea pump fulfills the working requirements of the SCR system, the urea pump requires to be adjusted.

After making use of SCR innovation, the engine's emission feature depends to a big extent on the calibration of the urea shot system and also the relative efficiency of the urea pump. Based upon the fundamental principle of nitrogen and oxygen reduction, the SCR gadget uses a 32.5% urea aqueous option as a minimizing agent, and under the catalysis of the stimulant surface area covering, the NOX in the exhaust gas is decreased to N2 and H2O.

The exhaust temperature of diesel engines is generally 200-500 ° C, which essentially satisfies the activity needs of the vanadium-based catalyst utilized in SCR. The NOX in the exhaust gas discharged by the diesel engine rapidly responds with the urea aqueous solution to produce nitrogen and water.

Urea Pump Function

Discerning Catalytic Decrease (SCR) innovation is just one of the NOX catalytic filtration innovations for diesel motor that meet stringent exhaust guidelines in the future. It has the advantages of good safety, low gas intake, as well as good sulfur resistance. Its functioning principle is to make use of urea option and NOX oxidation-reduction response to create N2, which is non-toxic to body, as well as release it right into the environment. The urea pump pumps the urea solution out of the urea container and carries the urea remedy to the nozzle through the sharing pipeline.

Working Principle

When supplying liquid to the urea shot system, the electric motor drives the supply pump to supply the urea service from the urea storage tank to the pressure chamber. A part of the urea remedy is made use of for shot and also a part is returned to the urea storage tank via the orifice.

In a reduced temperature level setting, in order to prevent pipeline blockage, the pump requires to empty the stress chamber # The controller instantly judges that it enters the vacant state. Right now, the supply pump quits working, and the on-off valve is opened at the same time. The urea option is withdrawed right into the urea tank.

Everybody intends to stay in even more eco-friendly city, it is a good idea to buy SCR urea pump controller can make life far better.

The urea pump pumps the urea remedy out of the urea tank as well as carries the urea solution to the nozzle via the conveying pipe.

The mechanical as well as hydraulic principle of the urea pump is shown in the number, which is generally composed of a motor, a supply pump, a reverse pump, an on-off shutoff, a pressure chamber, and an orifice. When providing fluid to the urea shot system, the electric motor drives the supply pump to provide the urea option from the urea tank to the stress chamber. A component of the urea remedy is made use of for injection as well as a part is returned to the urea storage tank through the orifice.
