Sure, let's translate the previous information about the DEF Pump into English:
The DEF Pump, also known as a urea pump or DEF (Diesel Exhaust Fluid) pump, is a specialized pump used to handle DEF (also called diesel exhaust fluid). DEF is a liquid used to reduce nitrogen oxide (NOx) emissions from diesel vehicles. It is injected into the exhaust gas through an SCR (Selective Catalytic Reduction) system, where it reacts with NOx to produce harmless nitrogen and water. The DEF Pump plays a crucial role in diesel vehicles, ensuring that DEF is accurately and consistently supplied to the SCR system.
Here are some detailed information about the DEF Pump:
I. Function and Application
Main Function: Extracts DEF from the storage tank and delivers it to the injector of the SCR system, where it is sprayed into the exhaust gas at the appropriate time.
Application Areas: Widely used in various diesel vehicles, especially those that need to meet strict emission standards, such as commercial vehicles and passenger cars.
II. Types and Specifications
Types: DEF Pumps can be classified into several types based on their drive methods, structural designs, and working principles, such as electric pumps, mechanical pumps, diaphragm pumps, etc.
Specifications: Different DEF Pumps vary in flow rate, pressure, voltage, power, and other specifications. For example, some pumps may have a lower flow rate and pressure, suitable for small diesel vehicles, while others may have higher flow rates and pressures, suitable for large commercial vehicles.
III. Technical Parameters
Pressure: The working pressure of the DEF Pump is usually determined based on the specific vehicle and SCR system requirements. Some pumps may have a maximum pressure limit, such as 1.0 Mpa (Megapascal) or higher.
Temperature Range: The operating temperature range of the pump is also an important technical parameter. Most DEF Pumps can operate within a wide temperature range, such as -10°C to +70°C (minus ten degrees Celsius to seventy degrees Celsius).
Pulse Unit: In some cases, the flow rate of the DEF Pump may be expressed in pulse units (e.g., mL/P, which stands for milliliters per pulse), facilitating precise flow control.
