Urea pressure sensors are manufactured in large quantities

Product description

The most basic function of urea solution for vehicle use is to convert nitrogen oxides in vehicle exhaust into harmless nitrogen and water, so that vehicles can meet the national emission standards. The most intuitive method is to listen to the sound, when the urea pump motor rotation will emit a buzzing sound, in order to judge whether the urea pump is working normally. When the urea pump does not burn urea, it means that the SCR system of the vehicle is not working at this time. The most common causes are damaged urea pumps, clogged urea lines or clogged nozzles. When urea does not burn after pressure failure, the part between urea pump and urea tank can be checked first; If the pressure builds successfully but the urea does not burn, the component between the urea pump and the nozzle needs to be checked. When the pipe or filter element is blocked, it will indirectly lead to the non-combustion of urea. Maintenance method: Do not disconnect the main power supply of the vehicle for at least 30 seconds after the engine is turned off. After engine flameout, the system should discharge the residual urea solution in the pipeline to avoid crystallization and blockage. This phase lasts for 30 seconds and then automatically shuts down. If the user does not add urea or uses inferior vehicle urea, the engine ecu will record excessive vehicle emissions. Specializing in the manufacture of intake manifold absolute pressure sensor, common Rail Pressure Sensor, hydraulic pressure sensor, injection molding machine special Pressure Sensor, Urea Pressure Sensor, Brake Pressure Sensor, Refrigerant Pressure Sensor, etc.
