Description
Technical field
The utility model is related to polymer-injecting pump plunger field, more particularly to a kind of new polymer-injecting pump plunger.
Background technology
The used polymer-injecting pump of injection station is generally three plunger polymer-injecting pumps, and the plunger of polymer-injecting pump, which is damaged, mainly two reasons, one
It is that coating is damaged；Two be that plunger and extension bar clamp connection position are damaged, as shown in figure 1, needing integrally to enter plunger when after abrasion
Row is changed, very unreasonable, waste of materials.
Utility model content
There is provided a kind of a kind of new polymer-injecting pump being convenient for changing for deficiencies of the prior art for the utility model
Plunger.
The purpose of this utility model is to be achieved through the following technical solutions：
A kind of new polymer-injecting pump plunger, including plunger, clip, the plunger body have in spring groove, the spring groove
Portion's connecting spring, the spring groove top has clip engaging groove, and the clip engaging groove upper right has pin inserting groove,
The clip engaging groove upper left-hand has jointing clip, the clip bottom inside jackscrew fixing hole, the clip engaging groove
It is intermeshed with clip engaging groove, clip bottom connecting spring, there is pin connecting hole, the pin in the middle part of the clip
Connecting hole is corresponding with jackscrew fixing hole, pin inserting groove, and connecting pins inside the pin connecting hole, the pin right-hand member is inserted
Enter in pin inserting groove, in the pin left end insertion jackscrew fixing hole, connection jackscrew, the top inside the jackscrew fixing hole
Silk inside side walls connecting pins side wall, the jackscrew outside side wall has operating groove.
The pin is formed from steel.
Beneficial effect：
Original plunger is structure as a whole with clip, when wear occurs, it is necessary to which overall changed, and this new note
Poly- pump plunger is made up of plunger with clip, and structure is more reasonable, and plunger is connected through a screw thread with clip, and convenient disassembly works as clip
When wearing and tearing, clip dismounting and change, plunger can be continuing with, be convenient for changing, reduced the turnover rate of plunger, improve
The service life of plunger, has saved material, while can be used in various model polymer-injecting pumps, cost-effective, simultaneously because plunger with
Clip is effectively to prevent clip from occurring screw thread with plunger and moving back mouth and rotation, spring is provided with plunger body using threaded connection,
Under the action of the spring, frictional force when clip is engaged with clip engaging groove is increased, while clip top passes through pin and post
Locking is fixed in portion beyond the Great Wall, and is locked by jackscrew, and the coupling part for being effectively prevented plunger and clip is moved back
Mouth and rotation.
Brief description of the drawings
Fig. 1 is existing plunger described in the utility model and extension bar clip abrasion comparison structure schematic diagram.
Fig. 2 is a kind of new polymer-injecting pump plunger cross-sectional view described in the utility model.
Embodiment
The utility model is described in further detail below according to drawings and examples：
A kind of new polymer-injecting pump plunger, including plunger 1, clip 5, the inside of plunger 1 have spring groove 2, the spring
The inside connecting spring 3 of groove 2, the top of spring groove 2 has clip engaging groove 4, and the upper right of clip engaging groove 4 has pin
Sub- inserting groove 11, the upper left-hand of clip engaging groove 4 has jackscrew fixing hole 6, the inside jointing clip of clip engaging groove 4
5, the bottom of clip 5 is intermeshed with clip engaging groove 4, the bottom connecting spring 3 of clip 5, and the middle part of clip 5 has
Pin connecting hole 9, the pin connecting hole 9 is corresponding with jackscrew fixing hole 6, pin inserting groove 11, in the pin connecting hole 9
Portion's connecting pins 10, the pin 10 is formed from steel, and in the right-hand member of the pin 10 insertion pin inserting groove 11, the pin 10 is left
In end insertion jackscrew fixing hole 6, the inside of the jackscrew fixing hole 6 connection jackscrew 8, the inside side walls connecting pins 10 of jackscrew 8
Side wall, the outside side wall of jackscrew 8 has operating groove 7, and original plunger is structure as a whole with clip, when wear occurs, needs
Integrally to be changed, and this new polymer-injecting pump plunger is made up of plunger 1 and clip 5, structure is more reasonable, plunger 1 and card
Hoop 5 is connected through a screw thread, and the dismounting and change of clip 5, plunger 1, when clip 5 weares and teares, can be continuing with by convenient disassembly,
The turnover rate of plunger 1 is reduced, the service life of plunger 1 is improved, has saved material, while can be used poly- in various models note
Pump, it is cost-effective, it is threadedly coupled simultaneously because plunger 1 is used with clip 5, is effectively to prevent clip 5 from occurring screw thread with plunger 1
Mouth and rotation are moved back, spring 3 is provided with inside plunger 1, in the presence of spring 3, clip 5 is increased and is engaged with clip engaging groove 4
When frictional force, while locking is fixed by pin 10 and the top of plunger 1 in the top of clip 5, and locked by jackscrew 8
Tightly, mouth and rotation are moved back in the coupling part for being effectively prevented plunger 1 and clip 5.
