Treatment method of the pneumatic valve pneumatic components, such as no action

, the phenomenon of shield tail oil pump, pneumatic valve pneumatic components such as action, make the shield to advance. , reason analysis system exists serious leakage points, compressed air pressure can not meet the specified value; Affected by water vapor, make the pneumatic control valve stem rust stuck; Air pressure is too high to make the pneumatic components of the return spring overload and fatigue fracture, pneumatic component failure. When installing system, prevention measures fitting of the pipe joints, prevent leakage. Check in use process, found that funnelled processed in a timely manner; Often open water drain valve of air bag under water, reduce water content in the compressed air and prevent pneumatic components from corrosion; According to design requirements correctly setting the system pressure, guarantee the normal work of the various pneumatic components. And governance approach to find gas leak point in the road, leak, the pressure recovery system; Repair or replace the damaged components.
