Hydraulic Impulse Hose Testing Machine

Overview

Using a proven concept, LINK has refined this hose testing machine to provide unparalleled safety and performance. The machine interface allows the operator to quickly set up tests, calibrate the system, and run stored test files. A vented chamber eliminates the possibility of an explosion from the buildup of test fluid vapors in the environmental chamber. Performance is enhanced by using a robust intensifier with a built-in servo valve. The built-in servo valve improves performance by increasing the natural frequency of the system. A special valve with lower hysterysis and threshold provides higher accuracy than a standard flapper-nozzle valve in this pressure control application.

Applications

  • Heating of air temperature to 150o C
