SCR Scania에 적합 2549339 요소 펌프

Urea pump is a new type of high-efficiency urea pump, is a key component of the automotive aftertreatment system to meet the China VI/Euro VI emission standards, the key design of the product includes the following five aspects:

The diaphragm liquid pump design separates the fluid from the motor, and the speed of the speed control motor is 800-3500RPM, which provides working pressure to the urea nozzle.

Antifreeze design, when the pump is turned off, the pressure in the pump will naturally decay (about 15 minutes), the main filter element will not be damaged by freezing, and the urea pump can withstand the volume of expansion of urea liquid after freezing.

The thawing capacity design comes from the coolant after the engine is heated up to circulate in the urea pump to thaw, and the urea liquid in the pump is thawed through the heat conduction characteristics of the metal structure.

It adopts aviation high-strength check valve design to improve the durability in the case of large flow of urea solution, strong anti-pollution ability, not easy to be blocked, stuck.

독립 회로는 모터 설계를 제어하고, 요소 노즐 끝의 압력 센서에 따라 사출 압력을 모니터링하고, 요소 펌프 모터의 속도를 제어하여 출력 압력을 보장하는 데 사용되며, 파이프 라인의 압력이 표준을 초과하지 않도록 압력 릴리프 밸브가 있습니다 시스템의 안전을 보장하기 위해 표준.
