JB cylinder work related content is introduced

JB cylinder work related content is introduced JB cylinder piston in the cylinder pressure parts. Each other so that both cavity to prevent piston gas, is equipped with piston sealing ring. Wear ring on the piston cylinder can be improved guidance, reduce the piston sealing ring wear, reduce frictional resistance. Long wear ring using polyurethane, ptfe, fabric material such as synthetic resin. By the width of the piston ring size and length of sliding parts necessary to decide. Sliding part is too short, easy cause early wear and jammed. The piston material commonly used aluminum alloy and cast iron, small cylinder piston made of brass. JB two-way sealing is realized by using the combination sealing ring on the piston cylinder, piston and piston rod using the pressure riveting link, no nut. With the exhaust his on the cylinder end cover, some are still in the end cover with buffering mechanism. Rod side on the end cover is equipped with the seal and shield, in order to prevent air leakage and outward from the piston rod to prevent external dust entering in cylinder. Rod side on the end cover is equipped with guide sleeve, in order to improve the orientation precision of cylinder, piston rod under the small amount of lateral load, decrease when the piston rod out under bending capacity, extending the service life of the cylinder. Guide sleeve is typically used before sintering oil bearing alloy, copper casting. End cover malleable iron is commonly used in the past, now to reduce weight and anti-rust, often use aluminum alloy die-casting, miniature cylinder with brass material.
