[0002] One of the most important and commonly used inspection methods for manufacturers is to use hydraulic pressure to inspect the waterways and explosion-proof performance of flameproof motors for mining. Due to the harsh environment underground in coal mines, the water quality used is poor and the water cooling system is often blocked. However, the motor return inspection not only affects the on-site production tasks, but also has high transportation costs. At the same time, the cost of building a hydraulic pressure test station for mining flameproof motors in various 4S shops that repair flameproof motors for mining is high, and the efficiency of use does not reach the economic efficiency of the investment. Therefore, there is an urgent need for a low-cost and portable hydraulic pressure test vehicle. Utility Model Content
