Description
Technical field
This utility model design relates to a kind of lining field, is specifically related to water jet pump lining.
Background technology
When water jet pump runs, axle high speed rotating, in order to improve the stability of axle, it is to avoid axle causes mill because of frictional heat
Damage, improve the service life of axle, all can fix a lining outside axle again, carry out countershaft protection.Lining is that current industry sets
The parts preventing axle from wearing and tearing that standby field is conventional, the internal face majority of current lining is a continuous surface, during use, in lining
Contact area between wall and rotating shaft is relatively big, and friction is big, and abrasion is more serious, and service life is short, and the replacement cycle is shorter.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of rational in infrastructure, weares and teares little, improves service life, just
Water jet pump lining in clamping.
In order to solve the problems referred to above, water jet pump lining provided by the utility model, including body, described body is annulus
Shape, described body includes upper gasket, lower gasket and main body, and the two ends up and down of described main body are covered respectively and are connected to upper gasket and underlay
Circle, the outer surface of described main body is convexly equipped with frictional layer, and the hole portion edge on described upper gasket and lower gasket has teeth groove.
Further, the diameter of described main body is more than the diameter in hole on upper gasket, meanwhile, more than the diameter in hole on lower gasket.
Further, the inwall of described main body is provided with several salient points, offers between these every two two adjacent salient points
Porose.
Further, several salient points described are that equal proportion circumference is arranged.
Further, described main body is provided with upper and lower two-layer frictional layer in appearance, is provided with between described upper and lower two-layer frictional layer
Groove.
Further, the apparent frictional layer of described main body is regular or irregularly shaped.
Further, described rule or irregularly shaped be linear, shaped form or rhombus.
Compared with prior art, the utility model has the advantage of, its overall structure is simple, in the outer surface projection of main body
Having frictional layer, it is simple to the installation of lining and dismounting, the hole portion edge on described upper gasket and lower gasket has teeth groove, then facilitate
The installation of water spray pump shaft, is provided with salient point in body interior, then be to facilitate countershaft fixing, prevent axle pine sliding, the most biphase at this
Offer porose between two adjacent salient points, facilitate the heat radiation of axle, thus improve the work efficiency of water jet pump, reduce lining
Wear intensity, extends service life.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model；
Fig. 2 is internal structure schematic diagram of the present utility model.
In figure: body 1, upper gasket 2, lower gasket 3, main body 4, frictional layer 5, teeth groove 6, salient point 7, hole 8, groove 9.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Below
Embodiment is used for illustrating this utility model, but is not limited to scope of the present utility model.
Embodiment 1
As shown in Figure 1 and Figure 2, the water jet pump lining that the present embodiment is provided, including body 1, described body 1 in annular,
Described body 1 include upper gasket 2, lower gasket 3 and main body 4, the two ends up and down of described main body 4 cover respectively be connected to upper gasket 2 and under
Packing ring 3, the outer surface of described main body 4 is convexly equipped with frictional layer 5, and the hole portion edge on described upper gasket 2 and lower gasket 3 has tooth
Groove 6, the diameter of described main body 4 is more than the diameter in hole 8 on upper gasket 2, meanwhile, more than the diameter in hole 8 on lower gasket 3, described master
The inwall of body 4 is provided with several salient points 7, offers porose 8 between these every two two adjacent salient points 7, and described several are convex
Point 7 is arranged in equal proportion circumference, and described main body 4 is provided with upper and lower two-layer frictional layer 5, described upper and lower two-layer frictional layer 5 in appearance
Between be provided with groove 9, the described apparent frictional layer of main body 45 is regular or irregularly shaped, described rule or irregularly shaped
Can be linear, shaped form or rhombus.
The water jet pump lining that the present embodiment is provided, its overall structure is simple, and the outer surface in main body 4 is convexly equipped with frictional layer
5, it is simple to the installation of lining and dismounting, 8, the hole on described upper gasket 2 and lower gasket 3 edge has teeth groove 6, then convenient spray
The installation of pump shaft, has salient point 7 main body 4 is internally installed, then be to facilitate countershaft fixing, prevent axle pine sliding, the most biphase at this
Offer porose 8 between two adjacent salient points 7, facilitate the heat radiation of axle, thus improve the work efficiency of water jet pump, reduce lining
Wear intensity, extend service life.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model know-why, it is also possible to make some improvements and modifications, these change
Enter and retouch and also should be regarded as protection domain of the present utility model.
