φ254-φ508 hydraulic testing machine product manual
The test hydrostatic pressure machine is used for hydraulic sealing test of φ254 ~ φ508 pipe. Using manual control, is the company's technical personnel independent design, development.
The equipment mainly consists of three parts: the water press body, water supply system, and hydraulic station.
Hydraulic press body:
The hydro pressure testing machine body including: main beam, fixed support, mobile support, mobile sealing head, pipe clamping device:
There are a total of three main beams, one end of which is connected to a fixed support by a column pin, and the other end is supported by a moving support to withstand the axial force generated by the water pressure in the pipe during the hydraulic test.
Located at the positioning end of the pipe and connected to the main beam through six column pins, it is equipped with a water filling valve, a pressure boosting pipe, and a pressure transmitter. The pipes can be filled with water through the water filling valve, and the pressure is increased through the pressurization pipe. The pressurization process is displayed by the pressure transmitter.
The movable support is connected to the movable sealing head by an oil cylinder. The movable support can be moved on the crossbeam according to the length of the pipe, and fixed with column pins after being moved to a suitable position. The movable sealing head is equipped with an exhaust valve for exhaust during pipe water injection. After the clamping device clamps the pipe, the sealing head is moved by the oil cylinder to clamp and seal both ends of the pipe.
The clamping device integrates pipe alignment and clamping, and is placed at both ends of the pipe on the bottom beam of the hydraulic press. It is fixed by a set screw to adjust the position of the pipe, and then the pipe is clamped.
