The pneumatic cylinder barrel is the space where the piston moves and where the fuel and oxygen are mixed to produce energy. The energy generated by the combustion of the fuel pushes the piston and transmits this force to the wheels to turn the vehicle.
Structural components of the pneumatic cylinder
1, Pneumatic cylinder barrel: the size of the inner diameter represents the size of the cylinder output force. The piston has to do a smooth reciprocating slide in the cylinder barrel, the surface roughness of the cylinder barrel inner surface should reach Ra0.8μm.
2, Pneumatic cylinder end cover: end cover with inlet and exhaust port, seal and dust ring to prevent outward leakage and dust mixed into the cylinder. There is also a guide sleeve to improve the precision of the cylinder guide, to bear a small amount of lateral load on the piston rod, reduce the amount of piston rod out of the bend, to extend the life of the cylinder.
3, Pneumatic cylinder piston: cylinder in the pressure parts, in order to prevent the piston left and right two cavities fleeing each other, with a piston seal ring. Piston wear ring can improve the cylinder guide, reduce the piston seal wear, reduce friction resistance.
4, Pneumatic cylinder piston rod: cylinder in the important parts of the force. Usually use high carbon steel, the surface by hard chrome plating, or use of stainless steel, to prevent corrosion, and improve the wear resistance of the seal.
5, Pneumatic cylinder seals: rotary or reciprocating movement at the parts of the seal called dynamic seal, static parts of the seal called static seal.
6, Pneumatic cylinder work to rely on the oil mist in the compressed air to the piston for lubrication. There is also a small part of the cylinder without lubrication.
