The stable operation of steam turbines is essential for each power plant. However, impurities, solid particles and corrosive substances in the turbine oil may affect the performance and service life of the turbine. Therefore, each system of the steam turbine is equipped with a fire-resistant oil filter element, such as the main oil pump, oil servo-motor, circulating pump, etc., to keep the fire-resistant oil clean and maintain the stable operation of the steam turbine.

Compared with the common hydraulic oil, the steam turbine fire-resistant oil has higher requirements for high temperature and high pressure resistance, which also makes the oil filter element OF3-20-3RV-10 used in the fire-resistant oil circulation pump very different from the common hydraulic oil filter element.

• Higher filtration accuracy: the EH oil filter element OF3-20-3RV-10 has a higher filtration accuracy, which can effectively remove solid particles, metal impurities and dust in the oil liquid and ensure the cleanliness of the fuel.
• Better high temperature resistance: the fuel temperature will rise during the operation of the steam turbine, so the filter element OF3-20-3RV-10 of the EH oil circulation pump shall have good high temperature resistance to ensure the stable filtration effect under high temperature environment.
• Better corrosion resistance: the anti-fuel filter element OF3-20-3RV-10 needs to have a strong corrosion resistance, because the fuel may contain acidic substances, and the filter element needs to maintain stable performance under the action of these substances.
• Better service life: the EH oil filter element OF3-20-3RV-10 shall have a longer service life during use, reduce replacement frequency and maintenance cost.
• Easy cleaning and replacement: easy cleaning and replacement shall be considered in the design of the circulating pump filter element OF3-20-3RV-10 for the convenience of daily maintenance.

Because the filter element OF3-20-3RV-10 has these characteristics, it can meet the requirements of steam turbine operation, so as to ensure the safety and stability of power plant operation.
