Fig. 1 is the plan of self-lubricating plunger pump of the present invention；
Fig. 2 is Fig. 1 A-A sectional views；
Fig. 3 is Fig. 1 B-B sectional views.
Embodiment
Refer to Fig. 1 to Fig. 3, the present invention provides a kind of self-lubricating plunger pump, including the pump housing 1, the power that is connected with the pump housing 1
Mechanism（It is not drawn into figure）, actuating unit（It is not drawn into figure）Rotating shaft connect and drive the first main shaft 2, generally, actuating unit
For motor, gear 1, the meshing gear 24 of gear 1 are fixed with the first main shaft 2, gear 24 is fixed on the second main shaft 5
On, the both ends of second main shaft 5 stretch out the first countershaft 6, the second countershaft 7 respectively, the main shaft of the first countershaft 6 and second
5 be concentric, and the second countershaft 7 and the second main shaft 5 are bias；First countershaft 6, the second main shaft 5 with covering respectively on the second countershaft 7
The 8, second dead axle is held provided with the first dead axle and holds 9 and dynamic bearing 10, and the first dead axle, which holds the 8, second dead axle and holds 9, to be fixed in the pump housing 1, is moved
Bearing 10 makees eccentric motion with 7 relative second main shaft 5 of the second countershaft；Symmetrical two groups of plunger assemblies, institute are provided with the pump housing 1
State two groups of plunger assemblies to be respectively arranged in Liang Ge balancing gate pits 11, one end and the inlet/outlet valve 12 of Liang Ge balancing gate pits 11 penetrate, another
End insertion to the position of dynamic bearing 10, the inlet/outlet valve 12 connects pressure regulator valve 13；The plunger assembly includes being inserted in balancing gate pit
11 plunger 14, wool felt 15 is arranged with the plunger 14, water seal 16, oil sealing 17 are respectively equipped with the both sides of wool felt 15,
The outer ring of water seal 16 against and be fastened on the inwall of balancing gate pit 11, oil sealing 17 and wool felt 15 against and be fastened on the inwall of the pump housing 1；
Towards inlet/outlet valve 12, the inner is resisted against the outer wall of dynamic bearing 10 for the outer end of the plunger 14；Infiltrated on the wool felt 15 organic
Oil.
The water seal 16 includes V-type water seal 18 and support ring 19, and the V-type water seal 18 is adjacent with wool felt 15.
The operation principle of the self-lubricating plunger pump of the present invention is made an explanation below：
The self-lubricating plunger pump of the present invention, the first main shaft 2 is driven by clutch by power set, the gear on the first main shaft 2
One 3 are rotated with, and rotary motion active force is driven to gear 24, because gear 24 is fixed on the second main shaft 5, the second master
Axle 5 rotates, and the second countershaft 7 for being arranged on the end of the second main shaft 5 rotates around the center line of the second main shaft 5, is set in
Dynamic bearing 10 on two countershafts 7 is so that relative second main shaft 5 makees eccentric motion, because the inner of two plungers 14 is against dynamic bearing
10 outer wall, when dynamic bearing 10 makees eccentric motion, alternately two plungers 14 can be promoted to make piston movement, the motion makes pressure
Volume change is produced in the Room of room 11, so as to be pressurized to the water in balancing gate pit 11, and highly pressurised liquid is exported from inlet/outlet valve 12
Spraying operation is carried out, while in the presence of pressure regulator valve 13, can adjust operating pressure（1-30Kgf/cm²）, to adapt to different need
Ask.
Plunger 14 is flooded profit during reciprocating motion of the pistons is made, and surface forms moisture film, plays lubrication.Separately
Outside, machine oil is instilled in advance in wool felt 15, machine oil can be lubricated to plunger 14.When plunger pump actually uses, it is understood that there may be
The water in balancing gate pit 11 to bring into wool felt 15, due to the unique water-based energy of attracting deposit of wool felt 15, the water brought into can play profit
Sliding effect.The many mutually auxiliary effects more than of the self-lubricating plunger pump of the present invention, have reached the effect of plunger self-lubricating.
In addition, rubber ring of the support ring 19 using flexible function, after V-type water seal 18 is worn, the energy of support ring 19
Auxiliary seal effect is played, prevents fluid seepage, has the function that to extend the life-span.
The self-lubricating plunger pump of the present invention can be applied to motor-driven, power spraye, cleaning equipment, dissipation utensil and other micro-
The ideal pump of spraying equipment, and the present invention can be applied to various two cylinders, three-cylinder plunger pump simultaneously.
In summary, self-lubricating plunger pump of the invention, can accomplish to exempt from butter self-lubricating, compact-sized, convenient installation,
Small volume, in light weight, maximum working pressure can reach 30Kgf/cm2.
