Hydraulic fluid circulation system for hydraulic testing of hoses and other components - has connecting pipes for test components fitted with temp. converters and controllable heating elements

摘要

Heatable connecting pipes (4, 5) with an inlet (12) and an outlet (13), a filling pump (7) and a pressure convertor (3) are integrated in a closed circuit for testing hydraulic components such as hoses (6). The inlet and outlet are part of the same connecting pipe (4). A h.p. piston pump (8) is connected to the closed circuit (2) which also has a control circuit with measuring and processing devices (34-37). A controllable metering valve (21) is connected between the filling pump and the closed circuit. A dump valve (27) is connected between the pressure convertor and the closed circuit. Pref. both connecting pipes are fitted with temp. convertors (16, 17) and controllable heating elements (18, 19). USE/ADVANTAGE - Hydraulic fluid circulation in testing equipment. Ensures uniform heat distribution and precise temp. control.
