Abstract

The invention discloses a backflow time and regeneration volume testing system for a composite dryer. The system comprises an industrial PC, a data acquisition card AI module, an air pressure sensor,a differential pressure sensor, a data acquisition card DO module, a duplex piece, an air storage tank, an electromagnetic valve, a silencer, an air cylinder and a reference cavity, wherein the industrial PC is simultaneously connected with the data acquisition card AI module and the data acquisition card DO module; the data acquisition card AI module is connected with the air pressure sensor andthe differential pressure sensor; the data acquisition card DO module is connected with the electromagnetic valve; the electromagnetic valve is connected with the air cylinder; the air pressure sensoris arranged at an air inlet and an air outlet of the composite dryer; the differential pressure sensor is arranged at the air inlet and the air outlet of the composite dryer; and the silencer is connected to the air outlet of the electromagnetic valve. The backflow time and regeneration volume testing system of the composite dryer can carry out rapid and stable testing, interference caused by human factors is avoided in the testing process, and the accuracy is greatly improved.

Description

technical field [0001] The invention relates to the field of product detection devices for electronically controlled braking systems, and relates to a composite dryer reflux time and regeneration volume testing system and method, which are applicable to the performance testing of dryers. Background technique [0002] Composite dryer is a new product combining air dryer and four-circuit protection valve. Among them, the automobile air dryer is mainly used in the automobile air brake pipeline to remove impurities such as moisture in the compressed air and provide dry and clean air for the automobile brake system; the four-circuit protection valve is used for automobile multi-circuit air pressure It can automatically close the failed circuit to ensure that the inflation and air supply of other circuits are not affected, thereby ensuring driving safety. [0003] At present, most domestic manufacturers have their own independent detection devices for automobile air dryers and fo...
