The oil pump inlet filter element YZ4320A-002 for steam turbine fire-resistant oil system is a key component installed in the steam turbine fire-resistant oil system and located at the suction end of the oil pump. Its main function is to filter the fire-resistant oil in the oil tank, remove impurities and particulate matter therein, ensure the cleanliness of the oil supplied to the oil pump, and thus protect the oil pump and the entire fire-resistant oil system from damage. The following is some important information about the oil pump inlet filter screen for steam turbine fire-resistant oil system:

Structure and material of filter element YZ4320A-002:

- Filter screen structure: Usually a folded filter element design is adopted, which can provide a larger filtering area in a limited space and improve the filtering efficiency.

- Filter layer material: Glass fiber is commonly used in the filter layer because it has good filtering performance, can effectively intercept tiny particles, and is corrosion-resistant and high-temperature resistant.

- Frame material: The frame is mostly made of stainless steel, which ensures the strength and durability of the filter screen. At the same time, the stainless steel material can withstand high working temperatures and pressures and adapt to the working environment of the fire-resistant oil system.

Characteristics and applications of filter element YZ4320A-002:

- High temperature resistance: Since the temperature of the fire-resistant fuel system is high during operation, the filter must have good high temperature resistance to ensure stable operation in high temperature environment.

- Filtration accuracy: According to system requirements, the filter has different filtration accuracy levels to meet different requirements for oil cleanliness.

- Applicable objects: Mainly used for filters, directly installed at the inlet of the oil pump to ensure that the oil sucked by the oil pump is clean and free of impurities.

Maintenance and replacement:

- Regular inspection and replacement of the filter is a necessary maintenance operation to prevent the filter from clogging, causing difficulty in oil pump suction or insufficient oil supply in the system, affecting the safety and efficiency of the turbine.

- The replacement cycle is based on the system operating conditions, oil quality conditions and manufacturer recommendations. It is usually necessary to monitor the oil cleanliness and filter pressure difference as a basis for replacement.

In short, the filter element YZ4320A-002 at the inlet of the oil pump in the fire-resistant fuel system of the turbine is an indispensable component to ensure the safe and stable operation of the turbine, and its performance directly affects the reliability and economy of the entire system. Proper selection, installation and maintenance are critical to maximize equipment life and operating efficiency.
