This product utilizes high-speed centrifugal force to rotate the impeller, impacting the concrete inner ring surface with water flow to measure the concrete surface's resistance to water jet erosion. Customers can freely adjust the flushing flow rate (10m/s to 40m/s) and flushing time. Due to the weight of the molded specimens, the product uses a hydraulic lifting and lowering box for loading and unloading, significantly reducing the need for manual crane assistance. The test box employs a refrigeration cycle system to control the temperature of the box (target temperature can be set). This equipment is a specialized instrument for measuring the high-speed water jet sand erosion resistance of various concrete inner surfaces.
