The servo system of the steam turbine requires extremely high oil cleanliness, which is crucial for the system performance and lifespan. The servo filter element DR0030D003BN/HC is an important key component, and its performance directly affects system stability. Here, we will explore the key parameters of the filter used in the steam turbine servo system from the perspective of performance evaluation.

Parameter 1: Filtering accuracy

Filtering accuracy is the most basic performance indicator of a filter element, reflecting its ability to remove impurities from the oil. The filtration accuracy is usually measured in micrometers（ μ m) In the servo system of steam turbines, there is a high requirement for filtering accuracy, usually within 0.1 μ Below m. In practical applications, it is necessary to select the appropriate filtration accuracy based on system requirements and operating conditions to achieve the best filtration effect.

Parameter 2: Flux

Flux refers to the volume of oil processed by the filter per unit time, reflecting the flow capacity of the filter element. The larger the flux, the more oil the filter element processes per unit time, and the more stable the system operates.

Parameter 3: Pressure drop

Pressure drop refers to the magnitude of pressure drop when oil flows through the filter element. Excessive pressure drop may increase the energy consumption of the oil pump, affecting the normal operation of the system. Therefore, the pressure drop of the filter element should be maintained within a reasonable range.

After understanding these evaluation parameters, the filtration accuracy, flux, pressure drop, etc. of the filter element can be actually measured through equipment such as oil filters, pressure gauges, and flow meters. This provides a strong guarantee for the normal operation of the system by selecting filter elements with better application performance.
