Connector hose pressure testing device using hot oil - simultaneously tests several hoses connected in parallel using heater and pump

摘要

The testing device allow several connector hoses (4) to be tested simultaneously for checking their wear characteristics. The hoses (4) are connected in parallel to a source of pressurised oil heated to a temp. of 135 degrees C. The pressure of the oil can be varied during the testing period for long intervals. The oil is supplied via a hydraulic pump (1) from a tank (2) and returned to the latter after passing through the hoses (4) via a servo valve (5), e.g. a three-way valve.
