Environmental protection dust collector dust collector cylinder structure of dust collector cylinder

Structure of the cylinder
The dust removal cylinder is composed of cylinder end cover, piston rod and seal. Its internal structure is as shown in the figure
Cylinder principle diagram
Cylinder barrel
The inner diameter of the cylinder barrel represents the output force of the cylinder. The plug should slide smoothly back and forth in the cylinder barrel. The surface roughness of the inner surface of the cylinder barrel should be as rough as that of the steel tube cylinder barrel. The inner surface should also be plated with hard chromium to reduce the friction. Small friction resistance and wear, and can prevent corrosion. In addition to using high carbon steel pipes, the cylinder material is also made of high-strength aluminum alloy and brass type cylinders. There are cylinders that use stainless steel tubes for magnetic switches or cylinders used in corrosion-resistant environments. The barrel should be made of stainless steel, aluminum alloy or brass
The cylinder piston uses a combined sealing ring to achieve two-way sealing, and the piston and piston rod are connected by riveting without nuts
End cover
Cylinder end cover There are air intake and exhaust ports on the top, and a buffer mechanism in the end cover for oil. There are sealing rings and dust rings on the side end cover to prevent air leakage from the piston rod and prevent external dust from mixing into the inside of the cylinder. There is a guide sleeve on the 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. The guide sleeve is usually made of sintered oil-containing alloy forward-inclined copper. Casting covers used to be malleable iron in the past. Nowadays, in order to reduce weight and prevent rust, aluminum alloy die-casting is often used, and some micro cylinders are made of brass. Mutual gas channeling, equipped with a piston seal ring. The wear-resistant ring on the plug can improve the guidance of the cylinder, reduce the wear of the piston seal ring, and reduce friction resistance. The length of the wear ring is made of polyurethane, polytetrafluoroethylene, synthetic resin and other materials. The width of the plug The moving part is determined by the size of the sealing ring and the necessary length of the sliding part. If the moving part is too short, it is easy to cause early wear and jamming. The materials of the plug are commonly used aluminum alloy and cast iron. The piston of the small cylinder is made of brass
Piston rod< br/>The piston rod is the most important force-bearing part in the cylinder. High carbon steel is often used, and the surface is hard chromium plated, or stainless steel is used to prevent corrosion and improve the wear resistance of the sealing ring
Sealing ring< br/>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 connection methods between the cylinder barrel and the end cover of the cylinder mainly include the following
Integral type Riveted type threaded connection type flange type tie rod type.
