Description
Technical field
This utility model relates to plunger pump technique field, particularly relates to the plunger displacement pump of a kind of band clamp.
Background technology
In A10VSO series axial plunger pump, the operation principle of pump is: plunger is after in variable coiling, power transmission shaft circles,
Pump completes oil-absorbing process.In oil-absorbing process, when plunger has the trend departing from variable dish, the elastic force that compression spring produces passes through
Thimble passes to ball-joint, return plate, finally makes the piston shoes on plunger tightly be attached on variable dish.But in the middle of actually used,
Particularly under 2000RPM-3000RPM rotating speed, a spring more step is compressed, and the elastic force that spring produces is not enough so that on plunger
Piston shoes be attached on variable dish, thus cause piston shoes mill monolateral, make static pressure supporting surface destroy.Axial plunger pump is for a long time at this
Work under state, ultimate failure.To this end, devise the plunger displacement pump of a kind of band clamp.
Summary of the invention
Technical problem to be solved in the utility model is to provide the plunger displacement pump of a kind of band clamp, designs one pair of clamp by return plate
It is pressed in together with plunger on variable dish, is then screwed on variable dish.The pulling force that screw produces be enough to overcome pump at height
Speed rotates lower plunger and departs from the power of variable dish, thus ensures that plunger will not lose efficacy because of high rotating speed.
This utility model solves its technical problem and be the technical scheme is that the plunger displacement pump providing a kind of band clamp, including passing
Moving axis, plunger and Plunger pump body, in described plunger pump body, lateral rotation is provided with power transmission shaft, this power transmission shaft both sides cloth
Being equipped with plunger, the head of each plunger all withstands the right side of the variable dish rotating installation on power transmission shaft, these piston shoes by piston shoes
On return plate is installed, described power transmission shaft part between two plungers is socketed with compression spring, this compression spring
Right-hand member is fixed, and the left end of described compression spring is connected with thimble, and this thimble withstands return plate one end, described variable dish
Right side is positioned at the return plate other end and is disposed with clamp, and this clamp has arc concave shape groove, described card near return plate side
Plate lower surface has arc-shaped slot along arc concave shape groove, and this arc-shaped slot clasps the return plate other end.
Supplementing as to the one of technical scheme described in the utility model, described arc-shaped slot is deeply total than return plate, piston shoes
Thick big 0.05-0.07mm.
Supplementing as to the one of technical scheme described in the utility model, described clamp uses tin bronze material to make.
Supplement as to the one of technical scheme described in the utility model, in the middle part of described power transmission shaft, be slidably fitted with ball-joint,
This ball-joint withstands one end of return plate, and described thimble withstands the other end of ball-joint.
Beneficial effect
This utility model relates to the plunger displacement pump of a kind of band clamp, designs one pair of clamp and return plate is pressed in together with plunger variable dish
On, then it is screwed on variable dish.The pulling force that screw produces be enough to overcome pump to depart from variable at high speed rotating lower plunger
The power of dish, thus ensure that plunger will not lose efficacy because of high rotating speed.

Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is expanded on further.Should be understood that these embodiments are merely to illustrate this reality
With novel rather than limit scope of the present utility model.In addition, it is to be understood that read this utility model lecture content it
After, this utility model can be made various changes or modifications by those skilled in the art, and these equivalent form of values fall within the application equally
Appended claims limited range.
Embodiment of the present utility model relates to the plunger displacement pump of a kind of band clamp, as Figure 1-3, including power transmission shaft 3, post
Plug 6 and Plunger pump body 10, in described Plunger pump body 10, lateral rotation is provided with power transmission shaft 3, this power transmission shaft 3 liang
Side is disposed with plunger 6, and the head of each plunger 6 all withstands the variable dish 4 rotating installation on power transmission shaft 3 by piston shoes 5
Right side, these piston shoes 5 are provided with return plate 1, and the described power transmission shaft 3 part between two plungers 6 is socketed with
Compression spring 8, the right-hand member of this compression spring 8 fixes, and the left end of described compression spring 8 is connected with thimble 7, this thimble
7 withstand return plate 1 one end, and the right side of described variable dish 4 is positioned at return plate 1 other end and is disposed with clamp 9, this card
Plate 9 has arc concave shape groove 11 near return plate 1 side, and described clamp 9 lower surface has along arc concave shape groove 11
