Product description

Urea Pressure Sensor common faults and solutions: urea Pressure Transmitter does not build pressure, no post-processing fault. First check whether the urea tube connection is normal; In addition, pull out the tube connector from the urea Pressure Sensor and blow air into the urea tank to see if there are bubbles in the urea tank. I found the pipes clean, too. After that, the urea pressure sensor inlet urea pipe inlet and urea pressure sensor return pipe return air outlet exchange. Therefore, the pressure of urea pressure transmitter is quickly established. After the power is turned off, the urea pressure sensor has a "call" suction sound. The connection between the urea pressure sensor and the urea nozzle is pulled out, and a large amount of urea spills out. The results showed that the urea pressure sensor could not be established because the urea tank leaked into the indirect head of the urea pressure sensor. Note: The urea pipe shall not be discounted, and the pipe joint shall not leak, otherwise it will affect the normal work of the urea pressure sensor. Urea pressure sensor creates pressure, but no sound absorption after stopping. Check that the urea pressure sensor pipe is properly connected and no urea pressure sensor is faulty. The urea pressure sensor pipe pressure is normal. However, after running for some time, urea was found to continue to overflow from the urea pressure sensor into the nozzle pipe joint. When pulling out the pipe joint, it was found that the SM pipe joint of the urea pressure sensor was tilted, resulting in poor seal of the quick joint and urea leakage. Insert the urea pressure transmitter into the urea pressure sensor tube connector after normal replacement.
