The aging testing equipment for drainage pumps consists of a main frame welded with 304 stainless steel square tubes and sealed with 304 # sheet metal. The testing platform is suitable for online comprehensive performance testing of water pumps, consisting of four independent testing stations that are not affected by each other. The device is equipped with a 10 inch display screen for setting up functions and displaying data. The device adopts a one click start detection, and the system automatically judges whether it is qualified or unqualified. Qualified - OK, Unqualified - NG. No need for dedicated personnel to operate, simplifying and facilitating the use of operators.  

The testing platform mainly consists of a testing platform, a water temperature control system, electrical parameter power acquisition, temperature acquisition, flow acquisition, vibration frequency acquisition, and an electronic control system. Test platform: Made of 304 # stainless steel structure welded together, the working platform is equipped with a water receiving tray below: made of 304 stainless steel, with a slope in the center of the water receiving tray and a drainage pipe at the lowest point, which can be recovered or discharged from the box through an external drainage valve. Control the water temperature of the water tank through the customer's self equipped heat pump cooling device
