The return oil filter HTGY300B.6 is a key component in the EH oil system of the steam turbine, mainly used to remove impurities in the oil and maintain the cleanliness of the system. Filtering accuracy is an important indicator for evaluating the filtration performance of filter cartridges, and we need to ensure that the accuracy of the filter cartridge meets system requirements. However, using cheap and inferior filter cartridges to achieve filtration accuracy that does not meet standards may lead to serious consequences. Here, we analyze the hazards of inferior filter cartridges and discuss the importance of ensuring filtration accuracy for filter cartridges.

If cheap and inferior filter elements are used, they will have the following effects on the EH oil system of the steam turbine:

1. Reduce filtration efficiency: If the filtration accuracy does not meet the standard, it means that the filter element cannot effectively filter out small particles and pollutants. These small particles and pollutants may enter key components in the hydraulic system, leading to component wear and failure. The reduced filtration effect will not guarantee the cleanliness and purity of the oil supplied by the EH oil system to hydraulic equipment.

2. Accelerated component wear: Key components in the turbine EH oil system, such as valves, pumps, etc., are crucial for the normal operation of the system. Poor quality filter cartridges with substandard accuracy can cause small particles and pollutants to enter these components, accelerating their wear and damage. This may lead to a decrease in system performance, frequent malfunctions, and even damage.

3. Impact on system reliability and stability: The EH oil system is one of the key lubrication and control systems of the steam turbine, which is crucial for the stable operation and reliability of the steam turbine. The inadequate filtration accuracy of inferior filter cartridges can lead to the accumulation and deposition of pollutants within the system, affecting its reliability and stability, and increasing the risk of system failure.

Why are these cheap filters prone to substandard filtration accuracy? We analyzed the following reasons:

1. Poor quality filter cartridges may use low-quality filter cartridge materials that may not effectively capture and retain small particles and pollutants, resulting in inadequate filtration accuracy.

2. Poor quality filter cartridges may have used substandard manufacturing processes, resulting in the structure and assembly of the filter cartridge not being tight and precise enough to achieve the expected filtration accuracy.

3. Poor quality filter cartridge manufacturers may have overlooked the quality control process, including the selection of raw materials and quality testing, resulting in substandard filtration accuracy of the filter cartridge.

In summary, the inadequate filtration accuracy of cheap and inferior filter cartridges can have a negative impact on the EH oil system of steam turbines, and may lead to component wear, system failure, and reliability issues. Therefore, selecting the HTGY300B. 6 filter element that meets the standards and is of reliable quality is an important part of ensuring the normal operation of the hydraulic system.
