A dual cylinder filter without a bypass valve with a filtration accuracy of 5-10um and a rated flow rate greater than 100L/min should be installed in front of the electro-hydraulic converter. A fine filter with a filtration accuracy of no less than 10um and a rated flow rate greater than the total system flow rate should also be installed on the return oil pipeline to prevent various wear particles generated during the long-term operation of the electro-hydraulic governor from entering the system. All oil filters must be equipped with a differential pressure transmitter. When working, all transmitters must be connected to alarm devices such as power, indicator lights, or buzzers, so that when the electrohydraulic converter oil filter element SVA9-N is blocked and sends a signal (when the inlet and outlet pressure difference is 20.35Mpa), the transmitter contacts will automatically close, and the relay, indicator light, or buzzer will be connected to send a signal. The operator can promptly detect and replace the filter element to ensure the normal operation of the system.
Attention
Clean oil is the key to avoiding system failures and extending the lifespan of various hydraulic components. Therefore, strict pollution control measures should be taken in all stages of design, manufacturing, installation, debugging, and daily maintenance to maintain the long-term cleanliness of the oil.
Therefore, once the oil filter in front of the electro-hydraulic converter or on the return pipeline sends a signal, it indicates that the electrohydraulic converter oil filter element SVA9-N has been blocked. If not replaced in a timely manner, the filter element will soon be squeezed out. The influx of dirt into the electro-hydraulic converter can immediately cause the electro-hydraulic converter and electro-hydraulic governor system to lose control, with extremely serious consequences. Operators must pay attention to this and do not take it lightly. To ensure the long-term reliable operation of the steam turbine generator unit (or water turbine generator unit), it is recommended to choose a filter with a high pressure differential resistance (pressure differential does not crack under 21MPa) and a filtration ratio of B5 (or β 10) Imported filter elements ≥ 75 are recommended.
