HY4740 Water Hammer Tester has been designed to determine the behavior of pipes and their connections when subjected to cyclic pressure shock. It can satisfy the testing requirements of plastic pipes, such as PP-R, PP-H, PE, PEX, composite pipes and fittings, which shall not fail when subjected to 10000 cycles under continuously alternating pressure. This instrument complies with the following international and industry standards: ISO: ISO 10508; ASTM: ASTM F1281; GB/T: GB/T 18991. The main machine consists of a pressure control unit, solenoid valve, sensor, pressure station, etc. The number of working positions can reach 6, and the maximum pipe diameter can reach Φ63mm. High-quality industrial PC control, easy to operate. Imported (Denmark) pressure control electric valve, high accuracy and stability. Imported (USA) water pressure station, excellent performance, long service life, low noise, no need for an air source. Adopt high-precision sensor, the control accuracy can reach ±0.05MPa of the set value. Technical Specification Model: HY4740 Pressure range: 0.05~1.5MPa or customized Pressure resolution: 0.01MPa Pressure cycle time: ≤2s Energy loss: 0.25% Cycling times: 1~10000 Working stations: 6 Pipe diameter: Φ16mm~Φ63mm Power supply: AC380V and AC220V, 50Hz, 6kw Dimensions: Main control unit: 600×550×1300mm Test chamber: 1450×900×1230mm
