Abstract

The utility model belongs to the field of automobile performance test systems and especially relates to an automobile water pump assembly sealing test system. An air compressing device is connected with a pressure-regulating valve through a pipeline. The automobile water pump assembly sealing test system is characterized in that the system further comprises a detection valve A, a detection valve B, a differential pressure sensor, a pressure transducer, and a sealing comparison container. The detection valve A is connected with a three-way pipe connected with a water pump to be tested and a three-way pipe connected with an inflation valve. The detection valve B is connected with a three-way pipe connected with the sealing comparison container and a three-way pipe connected with a blowoff valve. The differential pressure sensor and the pressure transducer are connected with the three-way pipe between the water pump to be tested and the detection valve A through a three-way pipe. The differential pressure sensor is connected with the three-way pipe between the sealing comparison container and the detection valve B. The automobile water pump assembly sealing test system is capable of accurately and inerrably displaying testing results of a total leakage pressure, a total leakage volume, a leakage pressure instantaneous value, a leakage volume instantaneous value, and the like according to corresponding signals; and the displaying of a green light indicates qualification while the displaying of a red light indicates disqualification.
