Abstract
A supercharging system integrated steel pipe hydrostatic testing machine water-filling apparatus comprises a low pressure cylinder body, a piston rod, a high pressure cylinder body and a water-filling head, etc. By controlling motion of the piston rod, internal pressure of a pipe is raised, pipe hydrostatic testing is realized, and the water delivery link is saved. During the pressure testing process, the water-filling head is prevented from being drawn back due to the effect of an anti-back block, and axial force is transmitted to a rack to make force on the whole structure to be more reasonable. Strength requirement of the whole body is reduced. A supercharging system and the water-filling apparatus are integrated. Thus, leak points are greatly reduced, supercharging efficiency is raised, the structure is simpler, operation is stable and reliable, safety is high, cost is low, and control is convenient.
