Abstract
The utility model relates to a manual variable displacement piston pump, which comprises a variable disk (1), a locknut (5), a hand wheel (6), a cylindrical pin (7), a reset piston bush (8), a reset spring (9), and a reset piston rod (10), wherein the upper end and the lower end of the variable disk (1) are respectively connected with one end of a variable piston bush (3) and one end of the reset piston rod (10), the other end of the variable piston bush (3) is sleeved on an ejector rod (4), an extending end of the ejector rod (4) is fixedly connected with the hand wheel (6) through the cylindrical pin (7), the other end of the reset piston rod (10) is sleeved on the reset piston bush (8), and the reset piston bush (8) is connected with a back cover of a piston pump through the reset spring (9). The manual variable displacement piston pump disclosed by the utility model is capable of manual variation, the stability and the reliability of a product can be improved.
Description
Technical field
The utility model belongs to the hydraulics field, particularly relates to a kind of manual Variable plunger pump.
Background technique
Existing A10VSO series plunger pump product has in the industry cycle used the long time, relevant index and performance, as: stepless accent discharge capacity, stability, reliability or the like are backward, can't satisfy present requirement of large-scale production.For this reason, need be with the key structure of A10VSO series plunger pump---the variable improvement of partly upgrading.
The model utility content
The utility model technical problem to be solved provides a kind of manual Variable plunger pump, can improve the stability of product.
The utility model solves the technological scheme that its technical problem adopted: a kind of manual Variable plunger pump is provided, comprises the variable dish, small plunger, variable piston sleeve; Push rod, locking nut, handwheel; Straight pin, return piston cover, Returnning spring; The return piston bar is characterized in that: described variable dish upper and lower end is link variable piston sleeve one end and return piston bar one end respectively, and the variable piston sleeve the other end is placed on the push rod; The external part of push rod connects fixedly handwheel through straight pin, and the return piston bar the other end is placed in return piston and puts, and the return piston cover is connected with the bonnet of plunger pump through Returnning spring.
Described variable dish upper and lower end is respectively through small plunger link variable piston sleeve and return piston bar.
Described push rod is locked through the bonnet of locking nut and plunger pump.
Beneficial effect
The utility model is variable manually, can improve stability, the reliability of product.
Description of drawings
Fig. 1 is the utility model general assembly schematic representation.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiments only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
As shown in Figure 1, a kind of manual Variable plunger pump comprises variable dish 1, small plunger 2; Variable piston sleeve 3, push rod 4, locking nut 5, handwheel 6; Straight pin 7, return piston cover 8, Returnning spring 9; Return piston bar 10 is characterized in that: described variable dish 1 upper and lower end is link variable piston sleeve 3 one ends and return piston bar 10 1 ends respectively, and variable piston sleeve 3 the other ends are placed on the push rod 4; The external part of push rod 4 connects fixedly handwheel 6 through straight pin 7, and return piston bar 10 the other ends are placed on the return piston cover 8, and return piston overlaps 8 and is connected with the bonnet of plunger pump through Returnning spring 9.
Described variable dish 1 upper and lower end is respectively through small plunger 2 link variable piston sleeves 3 and return piston bar 10.
Described push rod 4 is locked with the bonnet of plunger pump through locking nut 5.
Rotate handwheel 6, moment of torsion passes for to push rod 4 through straight pin 7, clockwise rotates, and push rod 4 advances inwards, and variable piston sleeve 3 one ends are withstood on push rod 4 tops, and variable piston sleeve 3 the other ends contact with small plunger 2 on the variable dish 1.When clockwise rotating handwheel 6, the inclination angle of variable dish 1 diminishes, the also corresponding minimizing of discharge capacity.Otherwise, rotating counterclockwise handwheel 6, variable dish 1 is under the promotion of Returnning spring 9, and it is big that the inclination angle of variable dish 1 becomes, the also corresponding increase of discharge capacity.Because variable dish 1 is the screw thread transmission of leaning on the push rod 4, thus its can stop in any position, and with locking nut 5 pinnings.Thereby realize the stepless variation of discharge capacity.
Claims (3)
