The Hydraulic Power Unit is comprised of an electromotor, oil pump, air cooler, servovalve, other controlling valves, integrating manifolds, a temperature sensor, and other hydraulic components. The servovalve, transducers, controller, and the testing software form a closed-loop control system. Hydraulic oil temperature is kept at its setting range by an air cooler. Under normal operating conditions, the temperature should be lower than 60°C (140°F), and its highest temperature cannot exceed 65°C (149°F). If the oil temperature is higher than 65°C (149°F), turn off the machine and contact MTS.
