TH70-450鋼管水壓試驗機
产品说明
   TH70-450鋼管水壓試驗機 TH70-450 steel pipe hydrostatic testing machine The machine is designed for medium-diameter steel pipe pressure testing, which consists of front-end and rear-end sealing head groups, retrogress-protected cylinder, barrier-free track tension beams, pipe clamping brackets, power station, boost pump system, and etc. Front-end sealing head group is mounted on the fixed support that is connected to the tension beams; rear-end sealing head group is mounted on a small cart that can be moving back-and-forth on the tension beams. The small cart is positioned on the tension beams by pins; pipe clamping brackets whose number may increase or decrease are also positioned on the tension beams by pins. During the pressure testing process, pipe clamping brackets tightly hold steel pipe, front-end and rear-end sealing heads eject and trap the two ends of the pipe respectively. When using the large-gap seal ring, first it needs to be pressurized for clasping the pipe firmly, and then water is fed into the pipe and pressurized. If using the U-type seal ring, after the pipe is trapped in, water can be directly fed into the pipe and pressurized. The ejection and positioning of rear-end sealing head is controlled by the hydraulic servo system, it can be positioned at any location within the stroke range of the cylinder, and it is suitable for pressure testing of steel pipes with different lengths. The entire process of pressure testing is controlled by a computer system. Pressure curves and related data are automatically recorded in a database for further analysis. Maximum bearing capacity: 4500 KN |
