In the power plant steam turbine system, EH oil pump FRD.WJA9.039A has become a key component to ensure the safe and efficient operation of the steam turbine with its excellent performance and stable operation. This oil pump is designed for high pressure, high temperature and high speed conditions, and is the core power source in the power plant steam turbine speed control oil system.

The main function of EH oil pump FRD.WJA9.039A is to provide high-pressure power oil for the main steam valve and speed control valve of the steam turbine. Through its precise oil supply control, these key components can move quickly, reliably and sensitively, thereby ensuring the safe and efficient operation of the entire steam turbine system. The outlet pressure of the oil pump is set between 14.5±0.5Mpa. After starting, it can supply oil to the system at a full flow rate of 85L/min, and at the same time supply oil to the high-pressure accumulator. This high-pressure oil supply method is crucial to ensure the precise regulation of the main steam valve and speed control valve of the steam turbine.

In addition to providing sufficient pressure and flow, the EH oil pump FRD.WJA9.039A also needs to work closely with other parts of the system such as magnetic oil filters, oil coolers, etc. to ensure the quality of the oil. It uses high-pressure fire-resistant oil (EH oil), which has good flame retardancy and fluid stability, high auto-ignition point, and can effectively prevent the risk of fire when high-temperature components leak. Therefore, the oil pump must not only meet the basic oil supply needs, but also play an important role in the oil quality management of the system.

In terms of oil quality management, the EH oil pump FRD.WJA9.039A is equipped with an ion exchange resin regeneration device and a dehydration device to maintain the stability and cleanliness of the oil and prevent moisture from affecting the oil quality. These measures effectively extend the service life of the oil and reduce system failures caused by oil problems.

In addition, the design and function of the EH oil pump FRD.WJA9.039A are flexible enough to meet the different needs of the power plant steam turbine during unit startup, normal load operation and abnormal operation. In the pre-starting stage, it can circulate oil in advance to increase the oil temperature and purify the system; during startup and normal load operation, it can adjust the oil supply according to different valve opening sequences and opening requirements; and in abnormal operation, it can quickly respond to the operation of the trip control component to ensure the safety and stability of the system.

In summary, the EH oil pump FRD.WJA9.039A provides reliable power guarantee for the power plant steam turbine with its excellent performance and stable operation. It is an indispensable and important part of the power plant steam turbine system and the key to ensuring the safe and efficient operation of the entire system.
