QGB cylinder model and structure is introduced

QGB cylinder model is introduced: guide the piston within the cylinder for the straight line reciprocating movement of the cylindrical metal parts. The air in the engine cylinder converts heat into mechanical energy by inflation; Gas in compressor cylinder piston compression to increase pressure. Turbine, rotary piston engine housing is usually also called 'cylinder'. Application areas: printing cylinder Tension control) , semiconductor ( Spot welding machine, grinding chip) , automation control, robot and so on. QGB cylinder structure: cylinder by cylinder, end cover, piston, piston rod and seal: : end cover on the end cover is equipped with inlet and exhaust his, some still on 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, to reduce weight and rust, often use aluminum alloy die-casting, miniature cylinder with brass material. : the piston in the cylinder piston 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. : the stress of the piston rod piston rod cylinder is the most important parts. Often use high carbon steel, hard chrome plating on the surface treatment, or the use of stainless steel, to prevent corrosion, and raise the wearability of seal ring. : seal rotating or reciprocating motion component seal is called dynamic seal, still a part of the seal is called static seal. Cylinder and the end cover of connection method basically has the following kinds: overall, riveting, type, flange type, rod type screw thread connection. : compressed air cylinder to work depends on the oil mist lubrication of piston. Also has a small number of free lubrication cylinder.
