Cylinder

Category:

Unlike non-standard oil cylinders, a cylinder is a track for piston movement. Gas burns and expands within it. Some residual heat from the gas can be dissipated through the cylinder wall to maintain the operating temperature of the engine. The types of cylinders are integrated and single-cast. Single castings are divided into dry and wet types. The piston rod is the most important load-bearing component in the cylinder. High carbon steel, hard chrome plating, or stainless steel is typically used to prevent corrosion and enhance the wear resistance of the sealing rings. When the cylinder operates, it must be lubricated with an oil mist from compressed air. There are also a small number of non-lubricated cylinders. The sealing of rotating or reciprocating parts of the cylinder is called dynamic sealing, while the sealing of static parts is called static sealing. The connection methods between the cylinder barrel and the end cap are as follows: integral, riveted, threaded, flanged, and tie rod. In addition to the static loads such as the pressure difference inside and outside the cylinder and the weight of various components, the cylinder also bears the reaction force from steam flowing out of the static blades and the forces exerted on the cylinder by various connecting pipes under hot and cold conditions. Under the influence of these forces, the cylinder is prone to plastic deformation and leakage.
