Abstract
The invention relates to a pump assembly, in particular to a pump impeller shaft for driving an impeller to rotate. The pump impeller shaft comprises a shaft body. One end of the shaft body is provided with a lead screw which is arranged concentric with the shaft body. The lead screw and the shaft body are connected integrally. The shaft body is provided with a limiting sleeve arranged in the circumferential direction of the shaft body. The pump impeller shaft is characterized in that the section, between the lead screw and the limiting sleeve, of the shaft body is sleeved with a sectional sleeve, the side wall of the end, corresponding to the lead screw, of the shaft body is provided with an axial positioning groove extending to the end face, and the inner side wall, corresponding to the axial positioning groove, of the sectional sleeve is provided with an outer protrusion. The pump impeller shaft is long in service life.
Description
Technical field
The present invention relates to a kind of pump assembly, is the impeller of pump axle rotated for impeller specifically.
Background technique
All know in the manufacture field of pump, the impeller of pump is fixed on impeller shaft.At present, the impeller of pump axle used in industry comprises axis body, and there is the screw mandrel in arranged concentric one end of axis body, is connected between screw mandrel with axis body in one, axis body has along its stop collar circumferentially.During installation, first impeller is set to impeller shaft from that one end that screw mandrel is corresponding; Then, nut loaded onto by screw mandrel, utilize nut to be pressed onto on stop collar by impeller.But impeller there will be the phenomenon of skidding in rotation process, and the axis body of this impeller shaft is directly connected with impeller, when there is skidding, impeller is comparatively large to the wearing and tearing of axis body, reduces the working life of impeller shaft.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of impeller of pump axle, and the working life of this impeller shaft is longer.
For solving the problem, provide following technological scheme:
Impeller of pump axle of the present invention comprises axis body, and there is the screw mandrel in arranged concentric one end of axis body, is connected between screw mandrel with axis body in one, axis body has along its stop collar circumferentially.Be characterized in that section of axis body between described screw mandrel and stop collar overlapping have to save overlapping, the sidewall of axis body one end that screw mandrel is corresponding has the axially locating groove extending to this end face, the joint cover madial wall that this axially locating groove is corresponding has outer lug.
Be described stop collar to further improvement project of the present invention to be connected with axis body by the mode of welding.The advantage of such improvement avoids utilization to obtain stop collar to the mode that axis body carries out turning, thus save material.
Take above scheme, have the following advantages:
Overlap due to that section of axis body between the screw mandrel of impeller of pump axle of the present invention and stop collar overlapping to have to save, the sidewall of axis body one end that screw mandrel is corresponding has the axially locating groove extending to this end face, the joint cover madial wall that this axially locating groove is corresponding has outer lug.In use, impeller set is on joint cover for this impeller shaft.Therefore, what impeller wore and tore when skidding is joint cover, avoids the problem damaging axis body because impeller skids, thus extends the working life of impeller shaft.
Accompanying drawing explanation
Fig. 1 is the structural representation of impeller of pump axle of the present invention.
Embodiment
Below in conjunction with accompanying drawing, impeller of pump axle of the present invention is described in further detail.
As shown in Figure 1, impeller of pump axle of the present invention comprises axis body 1, and one end of axis body 1 is provided with the screw mandrel 2 in arranged concentric, is connected between screw mandrel 2 with axis body 1 in one, axis body 1 has along its stop collar 3 circumferentially, this stop collar 3 is connected with axis body 1 by the mode of welding.That section of axis body 1 between described screw mandrel 2 and stop collar 3 overlaps to have and saves cover 4, the sidewall of axis body 1 one end of screw mandrel 2 correspondence is processed with the axially locating groove 5 extending to this end face, the joint of this axially locating groove 5 correspondence overlaps on 4 madial walls and has outer lug 6.
In use, impeller set is on joint cover 4 for this impeller shaft.Therefore, what impeller wore and tore when skidding is joint cover 4, avoids the problem damaging axis body 1 because impeller skids, thus extends the working life of impeller shaft.
Claims (2)
1. impeller of pump axle, comprises axis body (1), and there is the screw mandrel (2) in arranged concentric one end of axis body (1), is connected between screw mandrel (2) with axis body (1) in one, axis body (1) has along its stop collar (3) circumferentially; It is characterized in that the upper cover of that section of axis body (1) between described screw mandrel (2) and stop collar (3) has to save to overlap (4), the sidewall of axis body (1) one end that screw mandrel (2) is corresponding there is the axially locating groove (5) extending to this end face, joint cover (4) madial wall that this axially locating groove (5) is corresponding has outer lug (6).
2. impeller of pump axle as claimed in claim 1, is characterized in that described stop collar (3) is connected with axis body (1) by the mode of welding.
