The beneficial effects of the utility model are:
One, cylinder barrel directly adopts Precision Seamless Steel Tubes to process, and is simple in structure, easy to process, and interior circle can also be handled through hard chromium plating, effectively improves working life;
Two, there is the sealing of multiple tracks " O " shape seal ring at the superimposed place of cylinder barrel and front cover and rear end cover, and clamps by connecting rod, good sealing effect, and it is simple in structure, and convenient disassembly helps maintaining;
Three, " V " shape seal ring is a polymer composite, for asbestos packing or teflon packing, can effectively improve sealing effect and working life;
Four, the guide ring between front cover and piston rod and end cover and the piston rod can prevent that piston rod from the time running into front cover or end cover in operation, effectively prevents the wearing and tearing of piston rod appearance;
Five, piston ring is designed to a bowl type, and effectively anti-leak-stopping vapour improves sealing effect.
