The testing equipment for the alternating cold and hot life of booster pumps consists of a frame welded with 304 stainless steel square tubes and sealed with 304 # sheet metal. There is a water tray below the work platform: made of 304 stainless steel and installed below the fixed substrate of the tested water-cooled plate. The center of the water tray is equipped with a slope, and the lowest point is equipped with a drainage pipe, which is 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.. It mainly consists of a constant pressure water supply pipeline, a hot and cold water constant temperature device, a control system, and other parts. Suitable for comprehensive performance testing of water pumps in normal temperature water, high temperature water, and low temperature water. It adopts 5-channel pipe diameter output and is suitable for testing booster water pumps of various diameters. Each workstation is independently inspected and not affected by each other. The equipment is equipped with a 10 inch display screen for setting up functions and displaying data. It adopts one click start detection, and the system automatically provides constant pressure water supply, temperature PID constant temperature control, time on/off control, etc No need for dedicated personnel to operate, simplifying and facilitating the use of operators
