Abstract
The invention discloses a support oil cylinder of a cement pump truck. The support oil cylinder is characterized in that a square base is welded with one end of a cylinder barrel; a guide sleeve is connected with the other end of the cylinder barrel through a bolt; a piston rod is sleeved in the guide sleeve and is inserted into the cylinder barrel; a dustproof ring, a step seal, a first supporting ring, a piston rod sealing ring, an O-shaped ring and a retainer ring are arranged on the guide sleeve; a piston is arranged at one end, which stretches into the cylinder barrel, of the piston rod; and a Glyd ring and a second supporting ring are arranged on the piston. By the structure, the support oil cylinder has a compact structure, is good in sealing and pressure maintaining performance, has the characteristics of long-term pressure resistance and good sealing performance, and is suitable to be used on the cement pump truck.
Description
Technical field
The present invention relates to a kind of oil cylinder, is a kind of for the support oil cylinder on the cement pump truck specifically.
Background technique
