Description
Technical field
The utility model relates to oil drilling technology field, in particular to a kind of plunger provision for disengagement of plunger displacement pump.
Background technology
Cementing truck plunger displacement pump is used for to the liquid such as cement injection, drilling fluid in well, contain corrosive substance, solid impurity because plunger place under high pressure constantly moves back and forth and is transferred liquid, plunger wear is very fast, in order to improve plunger displacement pump operating efficiency, meet construction needs, should regularly change.Change when plunger, plunger displacement pump spiral cover need be opened, make plunger and pull bar disengaging with removal tool special shackle, plunger is changed from taking out in cylinder sleeve.But due to the limitation of some cementing truck structures, plunger is very difficult from taking out in cylinder sleeve: the first, on plunger, do not arrange anyly by the handle of plunger pull-out, cannot the application of force pull it; The second, plunger is inadequate from drag link end taking-up space; Put into from drag link end the cylinder that diameter is less plunger is ejected from the other end, because space is limit, cylinder is long to be put less than in the pump housing, shortly plunger can not be ejected, and the 3rd, the cement solidification that plunger front end is residual, the plunger resistance that moves ahead is very large.Dismounting at present can only be stretched in the pump housing plunger is little by little transferred to crowbar, wastes time and energy, and operating efficiency is extremely low, very easily causes the infringement of the parts such as plunger or the pump housing.
Utility model content
Technical problem to be solved in the utility model is, a kind of plunger provision for disengagement of easy to use, plunger displacement pump that efficiency is high is provided.
Therefore, the technical solution of the utility model is as follows:
A kind of plunger provision for disengagement of plunger displacement pump, comprise support, leading screw, handle and the draw bar coaxial with described leading screw, described support is only to have the hollow cylinder of an end face and on the sidewall of described support, be provided with at least one curing cement outlet, on described end face, have the screw coordinating with described leading screw, described handle is fixedly mounted on the upper end of described leading screw, be used for rotating described leading screw, the lower end of described leading screw is passed the screw on described end face and is fixedly connected with described draw bar, on described draw bar, establish and be processed with external screw thread away from one end of described leading screw, externally threaded rotation direction on described draw bar is contrary with the rotation direction of the screw thread on described leading screw, the total length of described leading screw and described draw bar is greater than the height of described support.
Wherein, the screw thread on described leading screw can be trapezoidal thread, more reliable.
Further, fixed installation one hex nut on described end face, outside described screw, is used to and rotates described support impetus is provided, convenient with spanner adjusting pole the position on leading screw.
Brief description of the drawings
Fig. 1 is according to the structural representation of the plunger provision for disengagement of the plunger displacement pump of the utility model embodiment;
Fig. 2 is according to the occupation mode schematic diagram of the plunger provision for disengagement of the plunger displacement pump of the utility model embodiment.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.It should be noted that, in the situation that not conflicting, the feature in the application's embodiment and embodiment can combine mutually.
As depicted in figs. 1 and 2, according to the plunger provision for disengagement of the plunger displacement pump of embodiment of the present utility model, comprise support 1, leading screw 2, handle 3 and the draw bar 4 coaxial with described leading screw 2, described support 1 is for only having the hollow cylinder of an end face and be provided with at least one curing cement outlet 11 on the sidewall of described support 1, on described end face, have the screw coordinating with described leading screw, described handle 3 is fixedly mounted on the upper end of described leading screw 2, be used for rotating described leading screw 2, the lower end of described leading screw 2 is passed the screw on described end face and is fixedly connected with described draw bar 4, on described draw bar 4, establish and be processed with external screw thread away from one end of described leading screw 2, externally threaded rotation direction on described draw bar 4 is contrary with the rotation direction of the screw thread on described leading screw 2, the total length of described leading screw 2 and described draw bar 4 is greater than the height of described support 1.
Wherein, the screw thread on described leading screw 2 can be trapezoidal thread, more reliable.
Further, fixed installation one hex nut 12 on described end face, outside described screw, is used to and rotates described support 1 impetus is provided, convenient with spanner adjusting pole 1 position on leading screw 2.
Wherein, in order to ensure the discharge effect of curing cement, curing cement outlet 11 conventionally needs wide 1cm, grows up in 10cm left and right.
In addition, on plunger 5, be provided with the screwed hole matching with the external screw thread on draw bar 4; When this instrument uses, first draw bar 4 is screwed in to the screwed hole on plunger 5, both are closely connected, then swinging mounting 1 makes on its pump housing 6 that withstands on plunger displacement pump, thereby rotary handle 3 makes leading screw 2 to support 1 inner rotary, plunger 5 be pulled out, because draw bar 4 is contrary with the thread rotary orientation on leading screw 2, so can not cause draw bar 4 to screw out from plunger 5.
In this technical scheme, by leading screw 2 and draw bar 3, plunger 5 is hauled out reposefully, easy to operate, time saving and energy saving, safe and efficient, and can effectively avoid plunger displacement pump parts to damage.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but within this embodiment is included in scope of the present utility model.
