Abstract

The invention provides an automobile vacuum pump performance detecting method and device, and belongs to the field of automobile performance detecting. According to the detecting method, the detecting device of an automobile vacuum pump is used for comprehensively detecting the vacuum performance, the vacuum sealing performance, the overspeed performance, the high-temperature resisting performance, the low-temperature starting performance, the variable speed durable performance, the vibration durable performance, the noise performance and the corrosion resisting performance of the automobile vacuum pump, whether the performance conforms to the regulation or not is judged according to related parameters, and accordingly the production quality of the automobile vacuum pump is effectively improved. The detecting device is used for achieving the detecting method. The detecting method and device are overall in performance detecting, and all performance of the automobile vacuum pump can be effectively detected.

Description

technical field [0001] The invention relates to a method and a device for detecting automobile components, in particular to a method and a device for detecting the performance of an automobile vacuum pump. Background technique [0002] At present, there is no effective method and device for testing various performances of automotive vacuum pumps, so the performance of automotive vacuum pumps cannot be evaluated, which directly leads to the inability to guarantee the production quality of automotive vacuum pumps.
