The invention relates to the technical field of a salt fog test device of a compressor, in particular to a driving device for the salt fog test of the compressor, which is characterized by adopting a closed box body, wherein a left compressor bracket and a right compressor bracket are arranged on an upper cover; a compressor is fixed on each compressor bracket; an air inlet is arranged on the boxbody; a driving mechanism is arranged in the box body; the driving mechanism is connected with a transmission gear outside the box body and adopts a transmission belt for connecting the compressor; an air compressor is connected with an input end of a pressure regulating valve; and the output end of the pressure regulating valve is connected with the air inlet of the box body to keep a barotropicstate in the box body and prevent salt fog from entering the box body and corroding parts. Compared with the prior art, the invention prevents the salt fog from being carried into the box body due tothe rotation of a transmission shaft and causing corrosion; a special magnetic sensor for rotation speed is used for measuring the rotation speed of the transmission shaft to achieve the purpose of stably controlling the rotation speed of a belt pulley of the compressor; and an air motor is substituted for an electro-motor in the device, electric wiring is reduced, and safety is improved in a high-humidity environment.
Description
[technical field] [0001] The invention relates to the technical field of a compressor salt spray test device, in particular to a driving device for a compressor salt spray test. [Background technique] [0002] During the salt spray test of the compressor, since the ambient temperature reaches above 35°C, the humidity reaches 100%, and the environment is full of salt spray particles, the bottom of the salt spray box is filled with salt water with a concentration of more than 5%, which has a serious corrosion effect on metal parts ; At the same time, due to the closed environment, the use of electric motors will cause the environment to overheat and eventually damage the motor. [Content of the invention] [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, using an air motor with a reducer as a pulley drive device, and at the same time sealing the drive system in a special corrosion-resistant plastic box, and applying a certain air ...
