Working principle of thin cylinder

SMC Thin Cylinder Belongs to a large category of SMC cylinders and is One of the flagship products of SMC pneumatic components. It is a cylindrical metal component that guides the piston in linear reciprocating motion. Its working principle is to convert most of the thermal energy into mechanical energy through expansion in the engine cylinder. The following will give you a detailed introduction to the structure of the SMC thin cylinder.

SMC thin cylinderConstruction Principle

1. Cylinder barrel: The inner diameter size of the cylinder barrel represents the output force of the cylinder. The piston needs to make smooth reciprocating motion in the cylinder barrel. The surface roughness of the inner surface of the cylinder barrel should not exceed Ra0.8um, otherwise the efficiency and effectiveness will be affected.

2. End cover: The end cover of the cylinder is equipped with intake and exhaust ports, and some also have different buffer devices in 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 to the outside and prevent external dust from mixingcylinder inside the cylinder.

3. Piston: The piston is a pressure-bearing part in the SMC thin cylinder. In order to prevent the left and right chambers of the piston from causing air blow-by, a piston sealing ring is provided during the design.

4. Piston rod: The piston rod is the most important force-bearing component in the SMC thin cylinder. It usually uses one of the raw materials of high carbon steel (to ensure the product has a relatively high use frequency and service life), the surface is hard chromium plated, or stainless steel is used to prevent corrosion and improve the wear resistance of the sealing ring.

5. Seal ring: The seal of the parts that rotate or reciprocate is called a dynamic seal. For the same reason, the seal of the stationary part is called a static seal.

How the thin cylinder works

The thin cylinder has a compact structure and a shorter axial dimension than an ordinary cylinder.Thin cylinderThere are two types of oil-lubricated thin cylinders and non-oil-lubricated thin cylinders. The piston of the thin cylinder is sealed with an O-ring seal. There is no air buffer mechanism on the cylinder head. A spring snap ring is used to fix the cylinder head and the cylinder barrel.
