If Fig. 1 is a kind of water-oil separating water hydraulic standing balance plunger pump seal of the present invention and lubrication piston structure, mainly include
Motorized drive unit camshaft 1, plunger 3, cylinder body 4, small plunger 9, Motorized drive unit are cam pivot hole, cam eccentric shaft side
It is respectively opened to both ends there are two arc-shaped oil groove, pentacle weel is installed, each end face of pentacle weel is provided with make-up oil at eccentric pivoted cams
Fuel feed hole totally 5, wherein five-pointed star crop rotation plane translation move, eccentric pivoted cams part is with respect to pentacle weel with angular speedTurn
It is dynamic.Pentacle weel contacts always with plunger base plane, connection lubricating oil fuel feed hole 2.1 and plunger sliding cavity 3.7, and with water
Square to relative motion, small plunger is installed in plunger pressure transmission cylinder 3.3, precision-fit annular gap；It is small
Plunger base is provided with annular oil groove 9.1, and lubricating oil enters annular oil groove through small plunger 9 and 3.3 annular gap of plunger pressure transmission cylinder
9.1, meanwhile, lubricating oil enters annular water tank 9.2 through oil duct 9.3；9.1 top installation hole sealing ring of small plunger annular oil groove
10.1 prevent oil leak to small plunger upper end water pressure chamber 3.4；Similarly, 9.2 lower section mounting hole of small plunger annular water tank is used
Sealing ring II10.2 prevents water from leaking into small plunger lower end lubricating oil pressure chamber 3.5,3.3 small plunger middle of stroke of plunger pressure transmission cylinder
Inevitably a small amount of water and lubricating oil mixed liquor outlet 3.8 are provided with, water flow passage connects water pressure chamber 3.4 and work in the middle part of plunger
Make chamber 3.1.Plunger 3 is connect with cylinder body 4 by guide ring and bar with sealing ring.Lubricating oil is introduced to column from lubricating oil inlet 4.1
Plug 3 is lubricated with casing wall 4, and hole sealing ring III10.3 and sealing ring IV10.4 is distinguished in lubricating oil lower end and upper end, to its into
Row seals, and equipped with guide ring below sealing ring III10.3, mainly undertakes plunger radial load.Sealing ring IV10.4 upper ends are provided with

It is connect respectively with feed liquor interface tube 6 and drain interface tube 8 with liquid check valve 7 is gone out.
A kind of water-oil separating water hydraulic standing balance plunger pump of the present invention（Motor）Sealing and lubrication piston structure work are former
Reason：
Such as Fig. 1, drive camshaft rotation that pentacle weel is driven to move downward when the motor is energized, plunger 3 is acted in 111 pressure of spring
Lower promotion plunger causes plunger base is remained with pentacle weel 2 to contact, and with certain pressing force.Low pressure lubricating oil is from bent axle
Low pressure lubricating oil inlet 1.1 enters, and enters lubricating oil low pressure chamber 1.3 through low pressure lubricating oil runner 1.2, through lubricating oil oil-in
2.1 enter plunger sliding cavity 3.7, small plunger are pushed to move upwards by entering lubricating oil pressure chamber 3.5 after lubricating oil runner 3.6
To the contact stop motion of the top of plunger pressure transmission cylinder 3.3, lubricating oil that when make-up pump high pressure pump liquid leaks.Plunger 3 is with pentacle weel 2
Downward imbibition, pressure in working chamber 3.1As negative pressure, but less than low pressure lubricating oil pressure, i.e. water passes through from feed liquor interface tube 6
Feed liquor check valve 5 enters working chamber 3.1, until eccentricIt is overlapped with plunger contour, andAway from plunger bottom surface it is farthest when stop inhale
Liquid.During imbibition, low pressure lubricating oil pressure is assumed to be, then the cavity pressure that works satisfaction, then
9 both ends pressure difference of small plunger, the bar sealing ring 10.1 and 10.2 at small plunger both ends can protect
Lubricating oil and water are not revealed completely in card imbibition process.
As shown in Fig. 2, when bent axle 1 is eccentricDuring plunger base, i.e., In the process, moisten
Lubricating oil high pressure chest 1.4 and lubricating oil oil-in 2.1 match, and play the role of sealing height and are pressed with.Pentacle weel 2 pushes plunger 3 upward
Movement, the reduction of 3.1 volume of working chamber lead to work cavity pressureIncrease, 3.1 pressure of working chamberPass through after reaching rated pressure
Go out liquid check valve 7 to discharge through drain interface tube 8.Meanwhile high pressure water passes through small plunger after water flow passage 3.2 and water pressure chamber 3.4
9 move downward pressure transmission to lubricating oil pressure chamber 3.5 so that 3.1 pressure of working chamberIt is pressed with lubricant reservoir pressure chamber 3.5
PowerIt is equal, i.e.,.After pressure oil and water are acted on by small plunger annular gap reducing pressure by regulating flow, close by sealing ring
Envelope, has few part water and the sealed circle I10.1 and sealing ring II10.2 of lubricating oil to flow out to form mixing liquid, is mixed through plunger
Liquid outlet 3.8 is discharged.Pressure oil enters sliding cavity 3.7 through lubricating oil runner 3.6, and 3.7 area of sliding cavity is taken in design
With plunger outer diameter areaIt is equal, since water pressure and lubricating oil pressure are equal, so, plunger base lubricating oil pressure and plunger
Top water pressure is equal so that plunger end face and pentacle weel are by fluid pressure balance, so as to substantially reduce pentacle weel 2 and plunger 3
The fretting wear of bottom.Extreme pressure lubricant and water enter annular oil groove 9.1 through small plunger 9 and 3.3 fit clearance of plunger pressure transmission cylinder,
Forced lubrication is played to small plunger and plunger pressure transmission cylinder 3.3.Meanwhile annular oil groove 9.1 is carried in the hydraulic pressure of small plunger circumferential direction
Lotus ensures the concentricity between small plunger 9 and plunger pressure transmission cylinder 3.3, effectively reduces small plunger 9 and plunger pressure transmission cylinder 3.3
Between fretting wear and leakage, improve greasy property.High pressure oil plunger bottom surface sliding cavity 3.7 through plunger bottom edge to
External leakage equally plays forced lubrication during plunger base ovfl, increase Hydraulic Elements reliability and
Service life.
Work as crankshaft eccentricIt goes toIt is overlapped with plunger contour, i.e.,When, and repeat above-mentioned imbibition and row
Liquid process.
Finally it should be noted that approximate specific embodiments of the present invention listed above.It is clear that the invention is not restricted to
Above example can also have many variations for ram type pump or motor.Those of ordinary skill in the art can be from the present invention
All deformations for directly exporting or associating in disclosure, are considered as protection scope of the present invention.
