Adblue Centrifugal pump

Adblue Centrifugal pump is an important part of the urea solution injection metering system. Its main function is to extract the urea solution in the urea tank and maintain a certain pressure, and then deliver it to the injection unit to meet the flow and pressure requirements of the injection metering system.

Adblue Centrifugal pump is Mainly composed of a motor, supply pump, reverse pump, switch valve, pressure chamber, orifice, etc. The pump has two working states, supply and empty. When supplying liquid to the urea injection system, the motor drives the supply pump to deliver the urea solution from the urea tank to the pressure chamber. A part of the urea solution is used for injection and a part is returned to the urea tank through the orifice.

In a low-temperature environment, in order to prevent pipeline blockage, the pump needs to empty the pressure chamber. The controller automatically judges that it enters the empty state. At this time, the supply pump stops working, and the on-off valve opens at the same time. The pump reverses the residual pressure in the pressure chamber. The urea solution is drawn back into the urea tank.
