Specific embodiment
A kind of energy-saving and high-pressure, long-range Isobarically Control axial variable plunger pump in conjunction with shown in Fig. 1-6, including plunger 1 and set
The swash plate 3 being located at outside transmission shaft 2；Certain plunger pump further includes the pump housing, cylinder body, swash plate seat, return plate etc., these due to using at
Cooking technique, not new improvement, details are not described herein again.
The transmission shaft 2 is located in the pump housing, one section of flight 21, the swash plate 3 is arranged on the axle body of swash plate 3
In disk towards plunger 1, flow deflector 22 is set outward along disk center；21 rotation direction of flight be will pump intracorporal medium to
The rotation direction of 3 water conservancy diversion of swash plate.The extending direction of the flow deflector 21 is bent and is conducive to medium to 3 edge flowing of swash plate.Described leads
Flow 21 more gradually becomes smaller to outer cross-sectional dimension.
Transmission shaft 2 is located in the pump housing, one section of flight 21 is arranged on the axle body of swash plate 3, and the swash plate 3 is towards column
In the disk of plug 1, flow deflector 22 is set outward along disk center；21 rotation direction of flight is will to pump intracorporal medium to swash plate 3
The rotation direction of water conservancy diversion.Pumped (conveying) medium in this way in the pump housing close to transmission shaft 2 has the tendency that flowing along transmission shaft 2 to swash plate 3, encounters
To flowing on the outside of swash plate 3 after the disk of swash plate 3, swash plate 3 and piston shoes CONTACT WITH FRICTION part (such as Tu4Zhong double dot dash line area can be flowed through
Shown in domain), be conducive to take away the heat that piston shoes friction swash plate generates.The fever and deformation of swash plate 3, piston shoes are reduced, piston shoes are improved
Wear-resisting property and service life.And medium constitutes U-shaped flow region between swash plate and transmission shaft, U-shaped bottom is located on swash plate,
One, the both ends of U-shaped along transmission shaft 2, another be just directed toward the feed inlet on plunger 1, also have to transfer efficiency on the whole bright
It is aobvious to be promoted, conveying energy consumption is reduced, is played the role of good.
One end of plunger 1 of the present invention is opposite with swash plate 3 and piston shoes are arranged, and centre bore is arranged in the center of the swash plate 3,
Centre bore is passed through for transmission shaft 2, which is greater than the thickness of transmission shaft 2, does not also need to seal between the two, this and existing skill
Art is almost the same.The piston shoes include boots body 4 and boots lid 5, and the boots body 4 is constituted towards the one side of plunger 1 and the end of plunger 1
Flexural pivot connection, bulb is arranged in the end of the flexural pivot connection i.e. plunger 1, spherical groove is arranged on boots body 4 or plunger 1
Bulb is set on end setting spherical groove, boots body 4, for the ease of the installation of return plate, the usual plunger 1 is opposite with piston shoes
Bulb 14 is arranged in one end, and the spherical groove matched with bulb 14 is arranged on the boots body 4.In order to reduce bulb 14 and spherical groove it
Between friction, better way is, setting extends along 1 length direction of plunger and penetrates through to 14 surface of bulb inside the plunger 1
The first lubrication hole 15.During plunger 1 stretches in cylinder body, liquid medium can enter flexural pivot by the first lubrication hole 15
Position, to constitute lubrication.
In order to improve the stability of boots body 4, as shown in Fig. 2, the ladder platform shape that the boots body 4 is rounded, it is of course also possible to
It is the boots body 4 using other shapes.Boots lid 5 is arranged in the one side of the boots body 4 towards swash plate 3, and the boots lid 5 passes through with boots body 4
Connection component connection, that is, be detachably connected between boots lid 5 and boots body 4 by connection component composition, consequently facilitating ball 6
Replacement.The connection component can be buckle pair, be also possible to bolt, pair of nut；But for the ease of boots lid 5 and boots body 4 it
Between connection, it includes compatible stud 12 and nut 13 that better way, which is the connection component, and the boots lid 5 is towards boots body
More studs 12 are fixedly installed in 4 one side, and multiple through-holes matched with stud 12, the spiral shell are correspondingly arranged on the boots body 4
Column 12 passes through through-hole and is locked by nut 13.The pearl slot of several spherical shapes is uniformly arranged between the boots body 4 and boots lid 5 and in pearl
Ball 6 is fitted in slot, the side of the ball 6 is stretched out outside boots lid 5, and the piston shoes are contacted by ball 6 with swash plate 3.In order to
Friction is further decreased, as shown in Fig. 2, quantity setting the second lubrication hole of multiple tracks of pearl slot can also be corresponded in the boots body 4
16, second lubrication hole 16 is connected to pearl slot and spherical groove, that is to say, that the corresponding ball 6 of second lubrication hole 16.
In conjunction with shown in Fig. 1 and 3,5 and 6,3 top of swash plate is radially extended backwards to the setting of the surface of plunger 1 along swash plate 3
The first connection otic placode 8 is arranged backwards to the surface of plunger 1 in sliding slot 7,3 lower part of swash plate.The sliding block 9 that setting matches in the sliding slot 7,
The sliding block 9 and one end of connecting rod 10 are hinged up in the side perpendicular to sliding slot 7, the other end and first of the connecting rod 10
The telescopic rod of cylinder 11 is affixed, and first cylinder 11 is flexible along the direction perpendicular to transmission shaft 2.First connection otic placode 8
It is hinged up with the telescopic rod of the second cylinder 20 in the side perpendicular to sliding slot 7, second cylinder 20 is along being parallel to transmission shaft 2
Direction is flexible.
The present invention collectively forms piston shoes in use, using boots lid 5, boots body 4, ball 6, and piston shoes connect with swash plate 3
During touching, rolling friction is constituted using ball 6, greatly reduces the damage as caused by friction between piston shoes and swash plate 3
Consumption, improves the wear-resisting property of plunger pump.Meanwhile after prolonged use, it without entire replacement piston shoes, and only needs from boots
Boots lid 5 is removed on body 4, and replaces ball 6, it is very easy to use.In addition, the present invention can greatly improve flow adjusting
Nargin, the range for adjusting flow are bigger.During adjusting, by the flexible of the second cylinder 20, can coarse adjustment swash plate 3 incline
Rake angle.By the flexible of the first cylinder 11, band movable slider 9 slides in sliding slot 7, can accurate adjustment swash plate 3 tilt angle, pass through
The mode that accurate adjustment is combined with coarse adjustment, the present invention when the angle to swash plate 3 is adjusted more precisely, adjustable range more
Greatly.
In order to guarantee that stability that sliding slot 7 of the present invention is connect with sliding block 9, better way are that the sliding block 9 is in I-shaped
The vallecular cavity section of type, the sliding slot 7 is in T shape, and the edge of 7 notch two sides of sliding slot is connected to top margin and the bottom of I-shaped sliding block 9
Between side.For the ease of the hinged of sliding block 9 and connecting rod 10, the second engaging lug is arranged towards the surface outside sliding slot 7 in the sliding block 9
Plate 17, the connecting rod 10 are constituted hingedly with sliding block 9 at the second connection otic placode 17.The rectangular triangle of the connecting rod 10,
The stability of connection can be improved.
