Automatic Hydro Testing Device with Proportional Control Using Hydraulic Servo

摘要

Disclosed in the present invention is an automatic water pressure test device with proportional control using a servo, which uses a hydraulic control means which senses change in the volume of a test object in accordance to a water pressure measurement applying to the test object in order to apply a hydraulic pressure corresponding to the water pressure to the test object. Therefore, the automatic water pressure test device can prevent economic loss due to damage caused by the separation of the test object from a clamping means, and workers safety accidents can be prevented due to high water pressure leaking during damage.
