In modern thermal power plants, steam turbines are crucial power generation equipment, and their operational safety and efficiency directly affect the stable operation of the entire power plant. In this process, the BFP main oil pump 70LY-34*2-1 plays a crucial role. As a cooling and lubricating oil pump for the main shaft of the steam turbine, the 70LY-34*2-1 pump adopts multiple excellent and reliable technologies in its design, ensuring important functions such as axial force balance, lubrication of underwater bearings, and shaft seal cooling of the steam turbine, providing a solid guarantee for the long-term stable operation of the steam turbine.

Firstly, the design of the 70LY-34*2-1 BFP main oil pump in terms of axial force balance is one of its technical highlights. During the operation of a steam turbine, axial force balance is crucial for reducing mechanical wear and extending equipment service life. The 70LY-34*2-1 pump achieves good axial force balance through precise fluid dynamics design and optimization, effectively reducing bearing wear and ensuring stable operation of the steam turbine.

Secondly, lubrication of underwater bearings is another key factor for the normal operation of steam turbines. The 70LY-34*2-1 pump can ensure sufficient oil lubrication of the bearings, even during high-speed operation, to maintain good condition of the bearings and prevent bearing overheating and wear caused by insufficient lubrication.

In addition, shaft seal cooling is also an indispensable part of steam turbine operation. The 70LY-34*2-1 pump effectively reduces the temperature of the shaft seal by providing an appropriate amount of cooling oil, preventing damage to the shaft seal caused by excessive temperature, and further improving the safe operation performance of the steam turbine.

In the operation of power plants, it is often necessary to adjust the operation mode of the feed water pump according to different operating conditions. Here, the flexibility of the oil pump 70LY-34*2-1 is reflected. When the unit starts or encounters a malfunction, an electric feed water pump can be used to ensure the stable operation of the feed water system; When the unit is operating normally, it can be switched to a steam driven feed water pump, with one running and one standby, ensuring both efficiency and safety.

The design of the BFP main oil pump 70LY-34*2-1 not only considers the safety and reliability of operation, but also fully considers the convenience of maintenance and repair. The structural design of the pump is reasonable, and the components are easy to replace, greatly reducing maintenance time and workload, and lowering maintenance costs.

In summary, the BFP main oil pump 70LY-34*2-1 has become the guardian of the cooling and lubrication of the turbine spindle due to its excellent performance and reliable design. In thermal power plants, it not only ensures the stable operation of steam turbines, but also improves the operational efficiency and economic benefits of the entire power plant. With the continuous progress of technology and the deepening of application, we have reason to believe that the oil pump 70LY-34*2-1 will play a greater role in the operation of future power plants.
