1. Introduction

Applied to high and low temperature gas pressure alternating test for turbocharger hose, intercooler hose, intercooler and hose joint in automotive turbocharger system.  Check whether the turbocharger hose and other specimens can complete the cycle times of the standard under high and low temperature conditions. It is specially designed for the test medium as gas, low impulse pressure, low impulse frequency, expansion amount of turbocharger hose, intercooler tube or intercooler.
