摘要
Abstract
After the oil pressure drop rate of the cylinder valve pressure oil tank in a certain hydropower station significantly increased,abnormal vibration occurred during the treatment process.By replacing the encoder of the cylinder valve opening and zeroing the stroke of the cylinder valve relay,it was found that the electrical zero drift and inaccurate zeroing method of the cylinder valve relay were the reasons for the significantly faster oil pressure drop rate and abnormal vibration.Finally,the zero position adjustment was carried out by rotating the digital cylinder in the direction of cylinder valve closure to make the cylinder valve of Unit 4 operate normally.关键词
