The primary task of the Control oil inlet filter element FRD.6NCW6.070B is to accurately filter the oil entering the steam turbine control oil system. During the operation of the steam turbine, various impurities such as metal particles, dust, oxides, etc. may be mixed into the oil. Although these impurities are small, they may cause serious damage to the precision components in the control oil system, such as servo valves, throttle valves, etc., affecting the control accuracy and operation stability of the steam turbine.

The Control oil inlet filter element FRD.6NCW6.070B uses advanced filtering materials and precise manufacturing processes, which can efficiently intercept various impurities in the oil and ensure that the cleanliness of the oil entering the control oil system meets the strict requirements of steam turbine operation. Its excellent filtering performance effectively extends the service life of various components in the control oil system, reduces equipment maintenance costs, and provides a solid guarantee for the long-term stable operation of the steam turbine.

Product advantages: excellent quality, reliable performance

(I) High-strength structural design

The structural design of the filter element fully considers the complexity and harshness of the turbine operating environment. It uses high-strength skeleton materials to ensure that the filter element can still maintain a stable structure without deformation or damage when subjected to high-pressure oil impact. This high-strength structural design not only ensures the filtering effect of the filter element, but also greatly improves the service life of the filter element and reduces the risk of downtime caused by filter element damage.

(II) Excellent corrosion resistance

The oil in the turbine control oil system usually contains certain additives and chemicals, which may corrode the filter element material during long-term operation. The FRD.6NCW6.070B filter element uses materials with excellent corrosion resistance, which can effectively resist the erosion of chemicals in the oil, ensuring that the filter element can still maintain good performance in harsh working environments. This feature enables the filter element to adapt to different types of control oils and provide reliable filtering solutions for various turbine application scenarios.

(III) Large dirt holding capacity, reduced replacement frequency

The FRD.6NCW6.070B filter element has a large dirt holding capacity and can effectively filter impurities in the oil for a long time. This means that under the same operating conditions, the filter element can be replaced less frequently, reducing the workload and downtime of equipment maintenance and improving the operating efficiency of the turbine. The design of large dirt holding capacity not only saves users the cost of filter element replacement, but also further improves the overall reliability of the equipment.

Technical parameters: meeting the stringent requirements of steam turbines

(I) Filtration accuracy

The filtration accuracy of the Control oil inlet filter element FRD.6NCW6.070B can accurately intercept tiny impurity particles in the oil and meet the strict requirements of the turbine control oil system for oil cleanliness. With such a high filtration accuracy, even extremely fine metal chips or other impurities are difficult to escape the “capture” of the filter element, thus ensuring that the precision components of the control oil system can work normally in a clean oil environment.

(ii) Working pressure

The filter element can fully adapt to the pressure changes of the turbine control oil system under different working conditions. Whether during startup, operation or shutdown, the FRD.6NCW6.070B filter element can work stably and provide reliable filtration protection for the control oil system. Its excellent pressure resistance enables the filter element to maintain good filtration effect and structural integrity when facing complex and changing working pressures.

(iii) Working temperature range

During the operation of the turbine, the temperature of the control oil will fluctuate with the changes in working conditions. The FRD.6NCW6.070B filter element has a wide operating temperature range and can work normally in an environment of [minimum operating temperature]℃ to [maximum operating temperature]℃. This feature ensures that the filter element can maintain stable filtration performance under various operating temperature conditions of the turbine, and will not affect the filtration effect or cause material performance degradation due to temperature changes.

As an indispensable and important part of the steam turbine control oil system, the Control oil inlet filter element FRD.6NCW6.070B has demonstrated strong performance and value with its precise filtering function, excellent product advantages, reliable technical parameters and a wide range of application cases. It not only provides a solid guarantee for the efficient and stable operation of the steam turbine, but also brings significant economic and social benefits to users. In the future, with the continuous development of steam turbine technology and the growing application demand, the FRD.6NCW6.070B filter element will continue to play its important role and contribute more to the development of the steam turbine industry.
