As a key device for controlling the speed and load of steam turbine, the performance of steam turbine electro-hydraulic speed governor directly affects the operating quality and economic benefits of the unit. In this process, the electro-hydraulic converter filter element SVA9N, as an important part of the electro-hydraulic speed control system, plays an irreplaceable role.

The SVA9N electro-hydraulic converter filter element is a high-precision filter element designed for steam turbine electro-hydraulic speed governor. It adopts advanced filtering materials and structural design, which can effectively intercept tiny particles, impurities and pollutants in the oil, ensure the cleanliness of the oil, and thus protect the electro-hydraulic converter from pollution and wear. The introduction of SVA9N filter element not only improves the stability and reliability of the electro-hydraulic speed control system, but also extends the service life of various components of the system.

Protecting the electro-hydraulic converter

The electro-hydraulic converter is the core component of the electro-hydraulic speed control system, responsible for converting electrical signals into hydraulic signals, driving the actuator to achieve the speed and load regulation of the steam turbine. However, impurities and pollutants in the oil can cause wear and blockage to the precision parts of the electro-hydraulic converter, affecting its performance and even causing failures. The SVA9N filter element effectively protects the electro-hydraulic converter by filtering impurities in the oil, avoiding performance degradation and failures caused by contamination.

Improve system stability:

The cleanliness of the oil directly affects the stability and response speed of the electro-hydraulic speed control system. The SVA9N filter element can continuously keep the oil clean, reduce system fluctuations and hysteresis caused by impurities, and improve the dynamic response capability and stability of the system. This is of great significance to ensure the smooth operation of the turbine during load changes, startup and shutdown.

Extend system life:

The long-term electro-hydraulic speed control system is susceptible to oil contamination, resulting in increased component wear and decreased sealing performance. The SVA9N filter element slows down the wear rate of system components and extends the service life of various system components by filtering impurities and contaminants in the oil. This not only reduces maintenance costs, but also improves the overall economic benefits of the system.

The SVA9N filter element is directly related to the stability and reliability of the electro-hydraulic speed control system. Once the filter element fails or the filtering effect is poor, it will lead to increased oil contamination, decreased system performance and even failure shutdown. This will not only affect the normal operation and power generation efficiency of the unit, but may also threaten the safety and stability of the power grid. By regularly checking and replacing the filter element, oil contamination problems can be discovered and dealt with in a timely manner to avoid system failures and component damage caused by contamination. This helps reduce maintenance costs, improve system reliability and economic benefits.
