Abstract
The utility model provides a shaft sleeve in an electric submerged pump for a well, belonging to the technical field of machines and solving the problems of poor wearing resistance and short service life of the existing shaft sleeve. The shaft sleeve is arranged in a shaft hole of a guide vane shell and comprises a barrel-shaped body which is made of rubber materials; and the inner end surface of the body is provided with a plurality of water distributing grooves along the radial direction. The shaft sleeve has the advantages that the wearing resistance is good and the service life is long.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of axle sleeve, particularly a kind of well axle sleeve in the stator shell in the Submerged Motor Pumps that is applied in.
Background technique
Existing well generally all is made up of pump case, motor, main shaft and a plurality of pumps unit with Submerged Motor Pumps, the pump unit is installed on the main shaft successively, wherein the pump unit is made up of impeller and stator shell, thereby pump draws up water come by the rotation of main shaft impeller in pump process.Because axle sleeve end face on the impeller and the axle sleeve end face on the stator shell are abutted together, and present axle sleeve all is to be made like this by metallic material, like this when the impeller high speed rotating, the comparison severity of axle sleeve on axle sleeve on the impeller and stator shell wearing and tearing, thus the working life of well influenced with Submerged Motor Pumps integral body.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed that a kind of wear resistance is good, long service life, is applied in well on the stator shell with axle sleeve in the Submerged Motor Pumps.
The purpose of this utility model can realize by following technical proposal: the axle sleeve of a kind of well in the Submerged Motor Pumps, be mounted in the axis hole of stator shell, comprise tubular body, it is characterized in that, described body adopts rubber material to make, and radially offers several bypass channels on the described body interior edge face.
By being opened in the bypass channel on the end face, make pump water in pump process can flow into axle sleeve end face on the stator shell and the space between the axle sleeve end face on the impeller, thereby the lubrication of playing, make this well with significantly improving the working life of Submerged Motor Pumps, the bearing wear resistance that adopts rubber material to make simultaneously is better.
In the axle sleeve in above-mentioned well usefulness Submerged Motor Pumps, described bypass channel is strip.
In the axle sleeve in above-mentioned well usefulness Submerged Motor Pumps, described bypass channel is evenly distributed on the body interior edge face.
In the axle sleeve in above-mentioned well usefulness Submerged Motor Pumps, the quantity of described bypass channel is 3～8.
In the axle sleeve in above-mentioned well usefulness Submerged Motor Pumps, described body internal surface is interior hexagonal configuration.
In the axle sleeve in above-mentioned well usefulness Submerged Motor Pumps, described body adopts the fine material of fourth to make.
Compared with prior art, this well with the axle sleeve in the Submerged Motor Pumps by being opened in the bypass channel on the end face, make pump water in pump process can flow into axle sleeve end face on the stator shell and the space between the axle sleeve end face on the impeller, thereby the lubrication of playing, make this well with significantly improving the working life of Submerged Motor Pumps, the bearing wear resistance that adopts rubber material to make simultaneously is better.
Description of drawings
Fig. 1 is the structural representation of the utility model when being installed in the stator shell.
Fig. 2 is a structural representation of the present utility model.
Among the figure, 1, the stator shell; 2, body; 21, bypass channel.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As depicted in figs. 1 and 2, this well is mounted in the axis hole of stator shell 1 with the axle sleeve in the Submerged Motor Pumps, comprise the tubular body made from rubber material 2, in the present embodiment, body 2 is to adopt the fine material of fourth in the rubber material to make, so just strengthen the wear resistance of axle sleeve, improved working life.
On the interior edge face of body 2, radially offer six bypass channels 21, bypass channel 21 is strip and is evenly distributed on body 2 interior edge faces, hexagonal configuration and body 2 were fixed in the axis hole of stator shell 1 in body 2 internal surfaces were, and can prevent that like this axle sleeve from coming off out from stator shell 1.Can play lubrication, thereby make this well so that pump makes water can flow into axle sleeve end face on the stator shell 1 and the space between the axle sleeve end face on the impeller in pump process by bypass channel 21 with significantly improving the working life of Submerged Motor Pumps.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
