Abstract
The utility model relates to arrive a kind of oil increasing machine vacuum pump piston M shape oil duct oil-control structure, including piston rod and piston head, piston rod is equipped with piston rod oil duct, annular rice word oil duct is arranged in cross-sectional direction inside piston head, piston rod oil duct connect and is connected to annular rice word oil duct, the cross sectional radius of eight branch's oil ducts of annular rice word oil duct gradually becomes smaller, and oil resistance device is installed in branch's oil duct.Structure design is simple ingenious, and the oil mass that can control filling is lost waste, and lubricating oil is made to be fully utilized.The period for extending filling oil can extend former 30 filling periods, save great amount of cost and artificial workload.
Description
Technical field
The utility model belongs to the plunger designs field of vacuum pump or cylinder, in particular to a kind of oil increasing machine vacuum pump piston
M shape oil duct oil-control structure.
Background technique
The violent reciprocating motion of piston needs lubricating oil to be lubricated at work for cylinder or vacuum pump cylinder body.If lacked
Few lubricating oil can damage cylinder body and piston seal, and will cause serious oil gas hallway pressure release.So must assure that true
There is lubricating oil to be lubricated in sky pump, such as oil production machine vacuum pump body, piston at every moment all move reciprocatingly in cylinder body, consumption
Oil mass is very big, and needs artificial frequent filling lubricating oil, need to fill within average 2-3 days primary.Existing piston oil duct waste
The lubricating oil of a large amount of lubricating oil, filling is not fully utilized, not only at high cost, and manually fills oily workload
Greatly.
Utility model content
To overcome defect of the existing technology, the utility model provides a kind of oil increasing machine vacuum pump piston M shape oil duct
Oil-control structure improves original piston, designs annular rice word taper oil duct, and oil resistance device is designed in oil duct, strictly
Oil mass is controlled, that is, reaches piston lubrication effect and reaches oil-control effect again.
In order to achieve the above object, using following technical scheme: a kind of oil increasing machine vacuum pump piston M shape oil duct oil-control knot
Structure, including piston rod and piston head, piston rod are equipped with piston rod oil duct, and annular rice word is arranged in the cross-sectional direction inside piston head
Oil duct, piston rod oil duct connect and are connected to annular rice word oil duct, the cross section half of eight branch's oil ducts of annular rice word oil duct
Diameter gradually becomes smaller, and oil resistance device is installed in branch's oil duct.
Further, oil resistance device is mutually wrapped to form cylindrical shape object by felt and steel wire.
For the utility model the utility model has the advantages that structure design is simple ingenious, the oil mass that can control filling is lost waste, makes to lubricate
Oil is fully utilized.The period for extending filling oil can extend former 30 filling periods, save great amount of cost and artificial work
It measures.
Detailed description of the invention
Fig. 1 is the utility model piston head internal galleries sectional view；
Fig. 2 is the utility model piston head internal galleries sectional view；
Fig. 3 is the utility model piston schematic diagram.
It is as shown in the figure: 1, piston rod；2, piston head；3, oil resistance device；4, priming cup；10, piston rod oil duct；20, annular
Rice word oil duct；200, branch's oil duct.
Specific embodiment
Embodiment
It further illustrates with reference to the accompanying drawing, the complete piston of one as shown in Figure 3 includes piston rod (1) and piston head
(2).Piston rod (1) is equipped with piston rod oil duct (10), and annular rice word oil duct is arranged in the internal cross-sectional direction of piston head (2)
(20), piston rod oil duct (10) connect and is connected to annular rice word oil duct (20).The annular rice word oil duct as shown in Fig. 2 and Fig. 3
(20) cross sectional radius of eight branch's oil ducts (200) gradually becomes smaller, and oil resistance device is installed in branch's oil duct (200)
(3).Oil resistance device (3) is mutually wrapped to form cylindrical shape object by felt and steel wire.Piston rod oil duct (10) directly with note
Lubricating cup (4) connection, in real work, priming cup (4) is mounted on one end that piston rod (1) is not connect with piston head (2).Profit
Lubricating oil flows into piston rod oil duct (10) from priming cup (4), into annular rice word oil duct (20), finally from eight branch's oil ducts
(200) it flows out, obstruction of the lubricating oil in branch's oil duct (200) by oil resistance device (3) slowly flows out, and plays piston head (2)
With the lubricating action of cylinder body and reach oil-control purpose.
Claims (2)
1. a kind of oil increasing machine vacuum pump piston M shape oil duct oil-control structure, including piston rod (1) and piston head (2), piston rod
(1) piston rod oil duct (10) are equipped with, which is characterized in that annular rice word oil duct is arranged in the internal cross-sectional direction of piston head (2)
(20), piston rod oil duct (10) connect and is connected to, eight branch's oil of annular rice word oil duct (20) with annular rice word oil duct (20)
The cross sectional radius in road (200) gradually becomes smaller, and installs oil resistance device (3) in branch's oil duct (200).
2. a kind of oil increasing machine vacuum pump piston M shape oil duct oil-control structure according to claim 1, which is characterized in that institute
The oil resistance device (3) stated mutually is wrapped to form cylindrical shape object by felt and steel wire.
