Mini Standard Cylinder

A cylindrical metal component that guides the piston through linear reciprocating motion in the cylinder. Air expands in the engine cylinders to produce heat.

To mechanical energy; The gas is compressed by a piston in the compressor cylinder to increase the pressure. Turbine, rotary piston engine

Shells, etc., are also commonly referred to as "cylinders". Applications: printing (tension control), semiconductor (spot welding machine, chip grinding), automatic control, robotics, etc.

Stainless steel mini standard cylinder construction

1. The cylinder is composed of cylinder barrel, end cover, piston, piston rod and seal, and its internal structure is shown as follows:

2: end cover

The end cover is provided with an air inlet and an air outlet, and some end covers are also provided with a buffer mechanism. The piston rod side end cover is provided with a sealing ring and a dust ring to prevent the piston rod from leaking gas and prevent external dust from mixing into the cylinder. The rod side end cap is equipped with a guide sleeve to improve the cylinder.

The guiding accuracy of the piston rod can withstand a small amount of transverse load on the piston rod, reduce the downward bending of the piston rod when extended, and extend the life of the cylinder. Guide bushing is usually made of sintered oil-bearing alloy and forward inclined copper casting. The end caps used to be made of malleable cast iron to reduce weight and prevent rust, usually aluminum die-cast parts, and the mini cylinders were made of brass.

3: Piston

The piston is the pressurized part of the cylinder. In order to prevent the left and right cavities of the piston from channeling each other, the piston sealing ring is provided. The resistance on the piston.

The wear ring can improve the direction of the cylinder, reduce the wear of the piston seal ring, and reduce the friction resistance. The wear ring is made of polyurethane.

Polytetrafluoroethylene, cloth clip synthetic resin and other materials. The width of the piston is determined by the size of the sealing ring and the length of the necessary sliding parts.

The sliding part is too short, which is easy to cause early wear and sticking. The piston is usually made of aluminum alloy and cast iron, and the piston for small cylinders is brass

4: piston rod

The piston rod is the most important force component in the cylinder. Usually high carbon steel, hard chrome plated surface, or stainless steel

Prevent corrosion and improve the wear resistance of the sealing ring.

5: Sealing ring

The seal of the component in rotation or reciprocating motion is called a dynamic seal, and the seal of the stationary component is called a static seal.

The connection modes of the cylinder and the end cover are: integral, riveted, threaded, flanged and pulled
