Abstract
The utility model discloses an oil slinger which comprises an oil slinger body (1). The oil slinger body (1) comprises an inner surface (101) and an outer surface (102), and the oil slinger is characterized in that the inner surface (101) and the outer surface (102) are sawtooth-shaped. The oil slinger can be installed in not only a multi-stage centrifugal pump, but also pumps with the similar structure or other systems. In the utility model, the original smooth surface of an inner hole of the oil slinger is changed into the sawtooth-shaped surface so as to enlarge the friction force between a pump shaft and the inner hole of the oil slinger, so that the rotating speed of the oil slinger along with the rotation of the pump shaft is quicker, in addition, the surface of the inner hole is sawtooth-shaped, so that more lubricating oil can be applied on the shaft, the lubrication between the pump shaft and a sliding bearing is sufficient, and the lubricating temperature is reduced, thus prolonging the service life.
Description
Technical field
The utility model relates to a kind of disc, particularly relates to a kind of endoporus with disc and is changed into the disc of installing on the centrifugal pump of serrated-surface by original smooth surface.
Background technique
In the installation of multistage centrifugal pump, in order to guarantee the lubricated of bearing, design oil supplying device, guarantee that the lubricant oil that bearing oil is indoor constantly is transported between sliding bearing and the pump shaft in a steady stream, if the fuel feeding deficiency will cause the wearing and tearing aggravation even the damage of pump shaft and sliding bearing.
The model utility content
At the problems referred to above, main purpose of the present utility model is to provide a kind of structure simpler, the smooth surface of disc endoporus is changed into the disc of the bearing lubrication structure that is installed in multistage pump of serrated-surface.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of disc, and described disc comprises the disc body, described disc body comprises internal surface and outer surface, it is characterized in that: described internal surface is a zigzag fashion.
In one embodiment, described outer surface is a zigzag fashion.
In another embodiment, described disc body is installed in the multistage centrifugal pump.
The utility model working procedure is simply as follows: during work, pump shaft rotates, drive disc and follow rotation, the adhesive force by disc and lubricant oil when disc rotates takes lubricant oil on the pump shaft to, because the smooth surface of disc endoporus changes serrated-surface into, increase with the frictional force of pump shaft, it is faster to make disc follow the speed that pump shaft rotates, again since endoporus toothing surface more lubricating oil can be taken on the axle, make pump shaft and sliding bearing lubricating abundant, reduce lubricated temperature.
Positive progressive effect of the present utility model is: the disc that the utility model provides has the following advantages:
The disc endoporus that the utility model relates to changes serrated-surface into by original smooth surface, thereby strengthened the frictional force of pump shaft and disc endoporus, it is faster to make disc follow the speed that pump shaft rotates, again because endoporus toothing surface, more lubricating oil can be taken on the axle, make pump shaft and sliding bearing lubricating abundant, reduce lubricated temperature, thereby increase the service life.
Because the disc after improving provides sufficient lubricating oil for pump shaft and sliding bearing, has avoided original in the wearing and tearing that it is too early that lack of lubrication makes sliding bearing are scrapped, and has prolonged the working life of unit.

Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.Fig. 1 is that the bearing lubrication structure of multistage pump of the present utility model concerns schematic representation; Referring to Fig. 1, pump shaft 3 is supported by sliding bearing 2, sliding bearing 2 is installed on the housing of multistage pump, upper surface at bearing support 4 has groove, disc body 1 hangs on the pump shaft 3, the lower end of disc body 1 is immersed in the lubricant oil 5, lubricant oil is contained in the cavity of object, during work, pump shaft 3 rotates, and drives disc 1 and follows rotation, adhesive force by disc body 1 and lubricant oil 5 when disc body 1 rotates takes lubricant oil 5 on the pump shaft to, because disc body 1 endoporus frictional force smooth and pump shaft 3 is very little, it is very low to follow pump shaft 3 rotational velocity, again because disc body 1 endoporus is smooth, lubricant oil 5 is easy to flow down from disc body 1 endoporus, cause provide lubricated oil seldom, make the sliding bearing oil starvation and add galling.
Fig. 2 is the structural representation of disc of the bearing lubrication structure of existing multistage pump; Fig. 3 is the structural representation of disc of the bearing lubrication structure of multistage pump of the present utility model.Disc comprises disc body 1, and disc body 1 comprises internal surface 101 and outer surface 102, and the utility model provides the disc after the improvement, and its internal surface 101 is a zigzag fashion, and outer surface 102 also can be zigzag fashion, as shown in Figure 3.Fig. 4 is the B place enlarged view of the utility model Fig. 3, as shown in Figure 4, the zigzag fashion of seeing internal surface 101 that can be very pure and fresh among the figure, after the sawtooth of internal surface 101 processed, the disc body 1 that processes so just can be installed in multistage centrifugal pump and suffer.
Disc endoporus after the improvement changes serrated-surface into by original smooth surface, thereby strengthened the frictional force of pump shaft and disc endoporus, it is faster to make disc follow the speed that pump shaft rotates, again because endoporus toothing surface, more lubricating oil can be taken on the axle, make pump shaft and sliding bearing lubricating abundant, reduce lubricated temperature, thereby increase the service life.
Because novel disc provides sufficient lubricating oil for pump shaft and sliding bearing, avoided original owing to the wearing and tearing that it is too early that lack of lubrication makes sliding bearing are scrapped, prolonged the working life of unit.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
