EH oil system of steam turbine is an emergency hydraulic system of steam turbine, which is used to provide power and control signals in case of emergency to ensure safe and reliable operation of steam turbine. The system usually consists of hydraulic pump, oil tank, control valve and actuator, etc.

The hydraulic pump is usually called the main oil pump. The piston pump PVH074R01AA1050000002001AB010A is a commonly used EH oil main oil pump. Its main function in the turbine EH oil system is to provide high-pressure hydraulic oil for controlling and operating various hydraulic actuators of the system. It draws the hydraulic oil from the oil tank through the reciprocating motion of the piston in the axial direction and transmits it to the hydraulic components in the system through the pipeline, such as servo valves, cylinders and turbine actuators.

In the steam turbine EH oil system, the working performance of the EH oil main pump PVH074R01A10A2500000001AB010A directly affects the response speed and control accuracy of the system. It needs to be able to provide sufficient hydraulic energy to meet the working requirements of each component of the system and maintain a stable output pressure and flow. At the same time, the pump needs to be reliable and durable to cope with the long time operation of the system and possible emergency situations. It is one of the key components in the system and ensures the safety and reliability of the steam turbine in case of emergency.
