Cylinder product overview
Cylindrical shape that guides the piston to perform linear reciprocating motion in the cylinder Metal parts. The working fluid expands in the engine cylinder to convert thermal energy into mechanical energy. The gas is compressed by the piston in the compressor cylinder to increase the pressure.
Composition of the cylinder
) Cylinder barrel
The inner diameter of the cylinder barrel represents the output force of the cylinder. The piston should slide smoothly back and forth in the cylinder barrel, and the surface roughness of the inner surface of the cylinder barrel should reach.
. The cylinder piston uses a combined sealing ring to achieve two-way sealing. The piston and piston rod are connected by riveting without nuts.
) Cylinder end cover
The end cover is provided with intake and exhaust ports, and some also have a buffer mechanism inside the end cover. The rod side end cover is equipped with a sealing ring and a dust ring to prevent air leakage from the piston rod and external dust from mixing into the cylinder. There is a guide sleeve on the rod side end cover to improve the guiding accuracy of the cylinder, bear a small amount of lateral load on the piston rod, reduce the amount of downward bending of the piston rod when it extends, and extend the service life of the cylinder. Guide sleeves are usually made of sintered oil-containing alloy, forward-inclined copper castings. In the past, malleable iron was commonly used for end caps. In order to reduce weight and prevent rust, aluminum alloy die-casting was often used, and brass materials were sometimes used for micro cylinders.
) Cylinder Piston
The piston is a pressure-bearing part in the cylinder. In order to prevent the left and right chambers of the piston from channeling air, a piston sealing ring is provided. The wear-resistant ring on the piston can improve the guidance of the cylinder, reduce the wear of the piston seal ring, and reduce friction resistance. The wear-resistant ring length uses materials such as polyurethane, polytetrafluoroethylene, cloth-filled synthetic resin, etc. The width of the piston is determined by the size of the sealing ring and the necessary length of the sliding section. The sliding part is too short, which can easily cause early wear and jamming. The materials of piston are commonly aluminum alloy and cast iron, and the piston of small cylinder is made of brass.
) Cylinder piston rod
The piston rod is the most important force-bearing part in the cylinder. Usually high carbon steel is used, the surface is plated with hard chromium, or stainless steel is used to prevent corrosion and improve the wear resistance of the sealing ring.
) Cylinder sealing ring
The seal of the rotating or reciprocating parts is called a dynamic seal, and the seal of the stationary part is called a static seal.
The main methods for connecting the cylinder barrel and the end cover are as follows
Integral type, riveted type, threaded connection type, flange type, and tie rod type.
) When the cylinder is working, it relies on the oil mist in the compressed air to lubricate the piston. There are also a small number of lubrication-free cylinders
