LV- 1104 hydraulic control valve fully open under normal working condition of fault analysis and processing

In a hydrogenation in the process of gear drive, gear drive feed 75 t/H feed pumps, reach a material balance LV- 1104 hydraulic control valve opening should be at about 69%, if the opening are increased under the condition of normal or even fully open, and the traffic is not increased, through the analysis considered regulator blocked. The meson situation and regulating valve body is the main cause of regulator is blocked. Cut out the regulator, the collapse of the regulator to clean up the impurity back to steam and water, is one of the effective methods to eliminate the problems.
