Subsidiary companies of Haichuan International Group:
Nanjing Ruiyan Energy Technology Co., Ltd. has the ability to design, modify, manufacture, and debug hydraulic servo systems;
The electric-hydraulic servo system includes: oil supply device (oil pump and oil tank), oil pipeline, accumulator, actuator part, emergency trip system, etc;
Type of electric-hydraulic servo systems: high-pressure fire-resistant oil system, low-pressure turbine oil EH control system;
The function and principle of electric-hydraulic servo system:
The electric-hydraulic servo system (EH) for rotating equipment is a necessary support system for power plant steam turbines, gas turbines, and other equipment. The EH system uses pressure oil as the medium to transmit and amplify the control commands issued by the control system. By controlling the opening of the turbine control valve and hydraulic motor, it achieves accurate control of fluid media such as steam and provides related protection functions.
