Bushing is used outside the mechanical parts to achieve sealing, wear protection and other functions of the accessories, refers to the role of the ring sleeve. In the field of valve application, the bushing is inside the valve cover, and corrosion resistant materials such as polytetrafluoroethylene or graphite are generally used for sealing.
The use of the bushing flexibility is relatively high, it can play a lot of roles, generally speaking, the bushing is a kind of parts for the protection of the equipment. The use of bushing can reduce the wear, vibration and noise of the equipment, and has the effect of anti-corrosion. The use of bushings can also facilitate the maintenance of mechanical equipment and simplify the structure and manufacturing process of the equipment.
The role of bushing in actual work has a lot to do with its application environment and purpose. In the field of valve application, the bushing is installed inside the valve cover to cover the valve stem, so as to reduce the leakage of the valve and achieve sealing effect. In the field of bearing applications, the use of bushings can reduce the wear between the bearing and the shaft seat, and avoid the increase of the gap between the shaft and the hole.
