The environmental pollution brought on by car exhaust has actually seriously affected the planet, as well as the development of the urea pump has outstandingly improved the environmental pollution caused by exhaust discharges. The crucial element for controlling diesel exhaust discharges is the urea pump controller, which has actually been extensively utilized in industrialized countries such as Europe. You need to know even more detailed details on it if you desire to buy SCR urea pump controller.
The urea pump is an integral part of the urea solution shot metering system. Its major function is to extract the urea solution in the urea container, maintain a specific pressure, and after that provide it to the injection system to meet the flow and also stress requirements of the shot metering system.
The Partnership In Between Urea Pump And Also SCR
The urea pump is the core element of the SCR system, and its efficiency is very closely related to the engine's emission function. In order to make sure that the working dependability of the urea pump fulfills the working requirements of the SCR system, the urea pump needs to be calibrated.
After using SCR technology, the engine's exhaust function depends to a large degree on the calibration of the urea injection system as well as the relative efficiency of the urea pump. Based upon the fundamental concept of nitrogen as well as oxygen decrease, the SCR gadget makes use of a 32.5% urea liquid option as a decreasing representative, as well as under the catalysis of the catalyst surface finish, the NOX in the exhaust gas is reduced to N2 and WATER.
The exhaust temperature level of diesel engines is usually 200-500 ° C, which generally satisfies the task requirements of the vanadium-based stimulant made use of in SCR. Therefore, the NOX in the exhaust gas discharged by the diesel motor swiftly responds with the urea liquid solution to generate nitrogen and water.
Urea Pump Function
Its functioning concept is to use urea remedy and NOX oxidation-reduction response to create N2, which is non-toxic to human body, and discharge it into the atmosphere. The urea pump pumps the urea remedy out of the urea storage tank as well as transfers the urea option to the nozzle through the sharing pipe.
Working Concept

1. Urea storage tank
2. Supply pump
3. Orifice
4. Stress chamber
5. On-off valve
6. Reverse pump
7. Motor).
The hydraulic and also mechanical concept of the urea pump is displayed in the number, which is primarily made up of a motor, a supply pump, a reverse pump, an on-off valve, a stress chamber, and an orifice. The pump has two working states, supply as well as vacant. When providing liquid to the urea shot system, the motor drives the supply pump to deliver the urea service from the urea tank to the stress chamber. A part of the urea remedy is used for shot as well as a component is returned to the urea tank with the orifice.
In a reduced temperature level atmosphere, in order to prevent pipeline clog, the pump requires to clear the pressure chamber # The controller automatically judges that it enters the vacant state. Currently, the supply pump stops working, and also the on-off shutoff is opened at the same time. The urea solution is withdrawed right into the urea storage tank.
The urea pump pumps the urea service out of the urea tank as well as moves the urea solution to the nozzle through the communicating pipe.
The mechanical and also hydraulic principle of the urea pump is shown in the number, which is primarily composed of an electric motor, a supply pump, a reverse pump, an on-off shutoff, a stress chamber, and also an orifice. When providing liquid to the urea injection system, the motor drives the supply pump to supply the urea service from the urea tank to the stress chamber. A part of the urea remedy is used for injection and also a component is returned to the urea storage tank via the orifice.
Everybody wants to live in more eco-friendly city, it is wise to buy SCR urea pump controller can make life far better.
