Automatic Hydrotest Unit for Heat Exchanger

Abstract

Hydrostatic test most formally known as hydrotest is a type of test that is performed to check leakage in weld joints and assembled parts of different parts of pressure vessel and pipe lines. Hydrotest involves the filling of water or liquid in the pressure vessel and pressured it and check whether there is any leakage by the of pressure gauge or transmitters. The automatic hydrostatic test bed system is the system to eliminate manual intervention and make the system automatic. This test bed uses proportional control technology to realize the automatic load and automatic control of hydraulic motor, greatly improved stability accuracy and strong controllability of the automatic test bed system.
