Use.
Utility model content
The utility model is mainly to solve the technical problem in the presence of prior art, small, no so as to provide a kind of friction
Stuck new inclined shaft pump occurs.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals:
New inclined shaft pump provided by the utility model, including cylinder body and plunger body, the plunger body are located in the cylinder body
Interior, the excircle of the plunger body is provided with multiple outwardly curved flanges, and the curved flanges are along the plunger body
Length direction is spaced apart, and inner surface of the periphery of the curved flanges also with the cylinder body is engaged, wherein, the post
The outer surface of cock body is also covered with molybdenum disulfide lubricating layer.
Further, the middle position of the plunger body is additionally provided with an oil trap to cave inward, the oil trap
Cross sectional shape is circular arc.
Further, the multiple arcs flange of the oil trap both sides respectively along the plunger body length direction at equal intervals
Distribution.
Further, the outer surface of the cylinder body is additionally provided with a nitriding protective layer.
Further, the radius of curvature of the circular arc of the curved flanges is 0.2-0.4mm.
The beneficial effects of the utility model are:By being provided with multiple outwardly arcs on the excircle of plunger body
Flange, it is engaged using the periphery of curved flanges with the inner surface of cylinder body, enables plunger body smoothly relative in cylinder body
It is mobile, avoid it is stuck caused by not parallel between plunger body and cylinder body, meanwhile, molybdenum disulfide is good non-oil solid lubrication
Agent, there is the characteristic of the low grade of high-low temperature resistant coefficient of friction, do coating on plunger body surface using molybdenum disulfide, plunger body can be strengthened
Self-lubricating between cylinder body, reduce the coefficient of friction of both contact surfaces, reduce heat energy caused by frictional force and friction, it is not only
On the one hand the adhesion of plunger body and cylinder body is prevented, extends the service life of cylinder body and plunger body, reduces cost and increase economic efficiency;
On the other hand, energy loss is reduced, improves mechanical efficiency and energy utilization rate, saves the energy, it is economic and environment-friendly.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of new inclined shaft pump of the present utility model;
Fig. 2 is the structural representation of the plunger body of new inclined shaft pump of the present utility model.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model
Define.
Refering to shown in Fig. 1-2, new inclined shaft pump of the present utility model, including cylinder body 1 and plunger body 2, plunger body 2 are located in
In cylinder body 1, the excircle of plunger body 2 is provided with multiple outwardly curved flanges 3, length of the curved flanges 3 along plunger body 2
Direction is spaced apart, and inner surface of the periphery of curved flanges 3 also with cylinder body 1 is engaged, wherein, the outer surface of plunger body 2
It is also covered with molybdenum disulfide lubricating layer.
The utility model utilizes arc by being provided with multiple outwardly curved flanges 3 on the excircle of plunger body 2
The periphery of flange 3 is engaged with the inner surface of cylinder body 1, plunger body 2 is smoothly relatively moved in cylinder body 1, is avoided
It is stuck caused by not parallel between plunger body 2 and cylinder body 1, meanwhile, molybdenum disulfide is good non-oil kollag, is had
The characteristic of the low grade of high-low temperature resistant coefficient of friction, coating is done on the surface of plunger body 2 using molybdenum disulfide, plunger body 2 and cylinder can be strengthened
Self-lubricating between body 1, reduce the coefficient of friction of both contact surfaces, reduce heat energy caused by frictional force and friction, it not only one
Aspect prevents the adhesion of plunger body 2 and cylinder body 1, extends the service life of cylinder body 1 and plunger body 2, reduces cost and improves economic effect
Benefit;On the other hand, energy loss is reduced, improves mechanical efficiency and energy utilization rate, saves the energy, it is economic and environment-friendly.
Preferably, in order to further reduce the friction between plunger body 2 and cylinder body 1, the middle position of plunger body 2 is also
Provided with an oil trap 4 to cave inward, in the present embodiment, a small amount of lubricating oil can be placed in oil trap 4, when the phase of plunger body 2
During for 1 high-speed mobile of cylinder body, lubricating oil can be lubricated to plunger body 2 and cylinder body 1.Wherein, the cross sectional shape of oil trap 4
For circular arc, it can so increase the oil yield efficiency of lubricating oil, improve lubricant effect.
Preferably, the multiple arcs flange 3 of the both sides of oil trap 4 is spacedly distributed along the length direction of plunger body 2 respectively.Collection
Lubricating oil in oil groove 4 can be uniformly lubricated both sides curved flanges 3, so as to reduce arc when plunger body 2 moves back and forth
Friction between flange 3 and the inwall of cylinder body 1.
And in order to improve the service life of cylinder body 1, the outer surface of cylinder body 1 is additionally provided with a nitriding protective layer 5.
In the utility model, if the radius of curvature of the circular arc of curved flanges 3 is excessive, the mill of curved flanges 3 can be accelerated
Damage, if radius of curvature is too small, not having prevents stuck effect, the curvature of the circular arc of the curved flanges 3 in the present embodiment
