High Pressure Fire-Resistant Oil Control System (EH-HHP)
About EH-HHP
EH-HHP includes an integrated independent oil source, providing a qualified high-pressure working oil source for the normal operation of the entire hydraulic control system. The working fluid uses phosphate ester fire resistant hydraulic oil, offering high positioning accuracy, large driving force, stepless speed regulation, and rapid shutdown protection, making it suitable for large units. Its main equipment includes an independent oil source unit (oil station, regeneration unit, accumulator, fire-resistant oil, etc.), a servo actuator (actuator, servo valve, OPC solenoid directional valve, etc.), a trip control system, and an oil pipeline system (oil pipelines and various valves).
