In the circulating oil circuit of the EH oil system of the steam turbine, the return oil filter element AD1E101-1D03V/-WF is an important component. Its main function is to filter the oil returning to the oil tank to remove metal shavings, dust, and other impurities generated during the operation of the steam turbine. It is installed on the return oil pipeline of the EH oil system, near the position of the oil tank. When the oil flows through the turbine components, it will carry various pollutants, which are captured when the oil flows through the filter element, thereby maintaining the cleanliness of the oil.

The correct selection and use of the oil return filter element AD1E101-1D03V/-WF is crucial to ensure its normal operation. How can we check the quality of the return oil filter element without professional testing equipment when selecting a filter element? Today we will introduce some simple visual and physical inspection methods to help you determine the quality of the filter element.

• Firstly, carefully observe the appearance of the filter element. Check if there is any obvious damage to the filter element, such as cracks, holes, or deformation. These damages may affect the filtering effect and service life of the filter element. In addition, observe whether the surface of the filter element is uniform and whether there are any fiber shedding or other abnormal phenomena.
• Next, gently press the filter element by hand to check if it is too soft or prone to deformation. This may indicate that the filtering material of the filter element is insufficient or of poor quality. On the contrary, if the filter element is too hard, it may indicate that the filtering material has become clogged or outdated.
• While ensuring safety, gently blow air or use an air compressor to blow through the filter element and check for good ventilation. A high-quality filter element should have good ventilation to ensure smooth oil flow.
• Check the size and specification requirements of the filter element to ensure that it meets the requirements of the system. The inappropriate size of the filter element may affect the normal operation of the system.
• If the same model of filter element has been used before, the appearance and performance changes of the new and old filter elements can be compared. The new filter element should not have significant performance degradation, otherwise it may indicate poor quality.
• In the absence of professional equipment, the filtering effect of the filter element can be indirectly judged by the color or cleanliness of the oil before and after replacing the filter element. The obvious lightening or improvement in cleanliness of the oil color indicates that the filter element has a good filtering effect.
• Check if the filter element is damp, moldy, or damaged during storage. Improper storage conditions may affect the effectiveness and lifespan of the filter element.

Although it cannot completely replace professional testing equipment, these simple inspection methods can provide a certain degree of judgment without professional equipment. If possible, it is recommended to use professional oil analysis equipment and filter testing benches to ensure the quality of the filter. The correct selection and maintenance of the return oil filter element can prolong the service life of the equipment, improve the stability and efficiency of the system.
