Abstract
The utility model relates to a cover that resets, concretely relates to novel duplex plunger cover that resets, including set body that resets, set body that resets includes and all is equipped with the hole that is arranged in the plunger piston rod to pass on two mounts by two mounts, two mounts closely spaced in the stroke sum of two plungers, when this cover that resets installs additional on the lubricating grease plunger pump, because the closely spaced in the stroke sum of two plungers of two mounts stating of cover resets, hole on the mount has the piston rod on the plunger to pass, so when the eccentric shaft promotes the removal of first plunger, the cover that resets also can be followed prism of first order piston rod beyond the great wall and removed, when the eccentric shaft promoted the removal of second plunger this moment, the cover that resets also can be followed prism of second order piston rod beyond the great wall and removed, and reset this moment and set can stimulate prism of first order piston rod beyond the great wall and remove, and then the piston rod that helps first plunger restores to the throne, and then wait for that the eccentric shaft promotes first plunger with prism of first order piston rod counterbalance beyond the great wall again and moves.
Description
Technical field
This utility model relates to a kind of reseting sleeve, is specifically related to a kind of novel double plunger reseting sleeve.
Background technology
Double plunger reseting sleeve is mainly used in grease plunger displacement pump, grease plunger pump structure is as shown in figure 1 and 2 at present, including motor 1, eccentric shaft 2, fixed mount 3, needle bearing 4 and block 5, check valve 6, manifold 7, oil pipe 8, four-way 9 and multiple plunger 10, the plurality of plunger 10 is fixing with fixed mount 3 to be connected, described eccentric shaft 2 is arranged on motor 1 outfan, the plurality of plunger 10 one end is arranged on eccentric shaft 2 by needle bearing 4, the other end of the plurality of plunger 10 is provided with check valve 6, described check valve 6 is connected with manifold 7 by oil pipe 8, described manifold 7 connects with four-way 9, it is outside that described block 5 is set in eccentric shaft 2, described fixed mount 3 is arranged on motor 1.
After there is the problem that plunger 10 is offseted by eccentric shaft 2 and then is carried forward stroke movement, it is impossible to reset.
Utility model content
For the problems of the prior art, this utility model provides a kind of novel double plunger reseting sleeve helping plunger return.
For realizing above technical purpose, the technical solution of the utility model is: a kind of novel double plunger reseting sleeve, including reseting sleeve body, described reseting sleeve body includes two fixed mounts, the hole that piston rod passes in plunger it is equipped with, the stroke sum being smaller than two plungers of said two fixed mount on said two fixed mount.
As improvement, described fixed mount is arc.
As improvement, described fixed mount includes fixed mount one and two fixed mounts two, and said two fixed mount two is connected and in a certain angle with fixed mount one respectively.
As improvement, described fixed mount one and fixed mount two are formed in one structure.
As improvement, also include top cover, described top cover and two fixing connections of fixed mount.
When can be seen that this practicality has the advantage that this reseting sleeve is installed on grease plunger displacement pump according to such scheme, the stroke sum being smaller than two plungers due to two fixed mounts that described reseting sleeve is stated, hole on fixed mount has the piston rod on plunger to pass, so when eccentric shaft promotes the first plunger to move, the piston rod that reseting sleeve also can be followed on the first plunger moves, when now eccentric shaft promotes the second plunger to move, the piston rod that reseting sleeve also can be followed on the second plunger moves, and now reseting sleeve can pull the piston rod on the first plunger to move, and then help the piston rod of the first plunger to reset, and then wait eccentric shaft offsets with the piston rod on the first plunger again and promotes the first plunger to move.

Accompanying drawing illustrates: prior art: 1, motor, 2, eccentric shaft, 3, fixed mount, 4, needle bearing, 5, block, 6, check valve, 7, manifold, 8, oil pipe, 9, four-way, 9.1, oil-out, 9.2, steam vent, 9.3, overflow valve, 10, plunger.
This utility model: 11, reseting sleeve body, 1.1, fixed mount, 1.2, fixed mount one, 1.3, fixed mount two, 1.4, top cover.
Detailed description of the invention
Embodiment one: as shown in figures 3 and 4, a kind of novel double plunger reseting sleeve, including reseting sleeve body 11, described reseting sleeve body 11 includes two fixed mounts 1.1, the hole that piston rod passes in plunger it is equipped with, the stroke sum being smaller than two plungers of said two fixed mount 1.1 on said two fixed mount 1.1；Described fixed mount 1.1 is arc.
Embodiment two: as depicted in figures 5 and 6, a kind of novel double plunger reseting sleeve, including reseting sleeve body 11, described reseting sleeve body 11 includes two fixed mounts 1.1, the hole that piston rod passes in plunger it is equipped with, the stroke sum being smaller than two plungers of said two fixed mount 1.1 on said two fixed mount 1.1；Described fixed mount 1.1 includes fixed mount 1 and two fixed mounts 2 1.3, and said two fixed mount 2 1.3 is connected and in a certain angle with fixed mount 1 respectively；Described fixed mount 1 and fixed mount 2 1.3 are formed in one structure；Also including top cover 1.4, described top cover 1.4 is fixing with two fixed mounts 1.1 to be connected.
When this reseting sleeve is installed on grease plunger displacement pump, the stroke sum being smaller than two plungers due to two fixed mounts that described reseting sleeve is stated, hole on fixed mount has the piston rod on plunger to pass, so when eccentric shaft promotes the first plunger to move, the piston rod that reseting sleeve also can be followed on the first plunger moves, when now eccentric shaft promotes the second plunger to move, the piston rod that reseting sleeve also can be followed on the second plunger moves, and now reseting sleeve can pull the piston rod on the first plunger to move, and then help the piston rod of the first plunger to reset, and then wait eccentric shaft offsets with the piston rod on the first plunger again and promotes the first plunger to move.
It is understood that above with respect to specific descriptions of the present utility model, be merely to illustrate this utility model and be not limited to the technical scheme described by this utility model embodiment.It will be understood by those within the art that, still this utility model can be modified or equivalent, to reach identical technique effect；Needs are used, all within protection domain of the present utility model as long as meeting.
