Abstract
The utility model relates to a piston type compressor, comprising a piston cylinder and a piston rod, wherein two O-shaped rings are arranged on the piston in a penetrating manner; a gap is arranged between the two O-shaped rings; and a positioning sleeve is arranged on the piston rod between the two O-shaped rings. In the piston type compressor, the structure is simple, the function is practical, the operation is safe and reliable, the manufacturing cost is low, and the lubricating oil on the piston rod can be effectively prevented from being taken into a cylinder.
Description
Technical field
The utility model relates to a kind of piston compressor.
Background technique
Also taked measure in the past for reducing oil consumption, the one, change scraper ring, the 2nd, eliminate the leakage of various lubricant oil, the 3rd, carry additionally O type circle retaining oil at underpart of the piston rod, prevent that lubricant oil from bringing cylinder into, but effect is all not obvious.Oil consumption is still higher.
The model utility content
The utility model purpose is to provide a kind of piston compressor, and is simple, safe and reliable to operation, and expense is cheap, prevents that the lubricant oil on the piston rod from bringing cylinder into.
To achieve these goals, the utility model adopts following technological scheme: a kind of piston compressor, comprise piston cylinder and piston rod, and be equipped with two O type circles on the described piston rod.
Be provided with the gap between described two O type circles, on the piston rod between two O type circles, be provided with setting sleeve.
The utility model is simple in structure, function is practical, and is safe and reliable to operation, cheap for manufacturing cost, can prevent effectively that the lubricant oil on the piston rod from bringing cylinder into.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Embodiment: as shown in Figure 1, a kind of piston compressor comprises piston cylinder 1 and piston rod 2, is equipped with two O type circles 3 on the piston rod 2.Be provided with the gap between two O type circles 3, on the piston rod 2 between two O type circles 3, be provided with setting sleeve 4.
The compressor piston rod upper and lower part increases simultaneously and hangs an O type circle, realizes two O type circle frizings, improves the frizing effect, thereby reduces the phenomenon of piston rod band oil, prevents that compressor oil from bringing cylinder into, thereby reaches the purpose that reduces oil consumption.
Claims (2)
1. a piston compressor comprises piston cylinder and piston rod, it is characterized in that: be equipped with two O type circles on the described piston rod.
2. piston compressor according to claim 1 is characterized in that: be provided with the gap between described two O type circles, be provided with setting sleeve on the piston rod between two O type circles.
