| Abstract: | Troubles caused by servo valve failures of electric-hydraulic control system obviously effect the safety and economical operation of steam turbines.An introduction is being presented to the construction of 760 series servo valves.Meanwhile the influence of acid values and particle sizes of phosphate hydraulic oil on the valve operation is analyzed,pointing out that erosion is the main reason which caused the valve failure of unit No.6 in Guodian Changyuan Shashi Thermal Power Plant. |
