The pump shaft thrust structure comprises a pump body and a pump shaft externally sleeved with a shaft sleeve, wherein the pump body is provided with a support seat with an axle hole in middle; and the pump shaft passes through the axle hole. The pump shaft thrust structure is characterized in that a rubber bearing is arranged outside the pump shaft at the axle hole; an insert is arranged on the support seat at the axle hole and is connected with a thrust plate; and the pump shaft is provided with a friction disk matched with the thrust plate. The pump shaft thrust structure can limit the shifting distance of the pump shaft along the axial direction, thus preventing the contact and friction between an impeller and a flow-guiding body and protecting the electric pump to run normally; the thrust plate and the friction disk are made of friction pair pairing materials, so that the pump shaft thrust structure has the advantages of high wear resistance, simplicity and convenience in process and manufacture and low cost; and furthermore, the electric pump is low in mechanical efficiency loss, and the thrust structure is long in service life.
Description
Technical field
The utility model relates to the electric pump technical field, especially a kind of pump shaft thrust structure.
Background technique
The deep-well Submerged Motor Pumps is because increase space or axial dimension will cause cost significantly to rise; So all require project organization compact, but compact structure just means that the gap between impeller and the deflector is as far as possible little, when electric pump moves under different operating modes; Will drive the pump shaft axial motion when producing axial force; When the distance of axial float surpasses the gap between impeller and the deflector impeller will with deflector grazing or wearing and tearing, influence the electric pump performance, even causes electric pump to be damaged.
The model utility content
The purpose of the utility model is for the deficiency that solves above-mentioned existing technology a kind of axial force of bearing to be provided, and limits the make progress pump shaft thrust structure of play of pump shaft.
In order to achieve the above object, a kind of pump shaft thrust structure that the utility model designed comprises the pump housing and is with the pump shaft of axle sleeve outward; The supporting base in tape spool hole in the middle of being equipped with on the described pump housing; Described pump shaft is located in this axis hole place, it is characterized in that the pump shaft that is in the axis hole place is provided with rubber bush bearing outward, is on the supporting base at axis hole place an inserts is housed; Connect a thrust button on the described inserts, the friction disk that matches with thrust button is housed on the described pump shaft.When electric pump moves under different operating modes; Displacement before and after often taking place up and down; Rubber bush bearing has played fixing up and down to pump shaft and has played buffer function, and thrust button is fixing before and after through the conflict friction disk pump shaft having been played, and limits the play distance of pump shaft; Prevent contacting and friction between impeller and deflector, the normal operation of protection electric pump.
Improve and replenish as the further of said structure, the utility model also comprises the combination in any of following additional technical feature or these characteristics:
Described thrust button is a middle disk that has through hole; Have a plurality of water-flowing troughs on the described disk end face; Make its surface form one deck fluid film lubrication friction pair, the gap of certain distance is arranged between two friction pairs, can reduce the loss of electric pump mechanical efficiency like this; Increase the life-span of thrust button, and can get rid of the granule impurity of surface of friction pair through this groove.
Described thrust button center of circle direction and pump shaft gap are provided with, and the outside and friction disk gap are provided with, and the gap of thrust button and friction disk is less than the gap of impeller and deflector, and water pump is played a protective role.
Described thrust button and inserts interference fit cooperate tight, easy for installation.
Described friction disk has the Hexagon through hole, and described pump shaft passes this through hole, and through the Hexagon carry-over moment, transmission efficiency is high.
Described thrust button is a composite material, and wear resistance is good; Described friction disk is a stainless steel, and hardness is high.
A kind of pump shaft thrust structure that the utility model obtains; Overcome axial force change that electric pump produced influence and destruction to water pump when the operation of different operating modes; The restriction pump shaft prevents contacting and friction between impeller and deflector in axial play distance, the normal operation of protection electric pump; The friction pair pairing material that thrust button and friction disk adopted has high wear resistance, and manufacturing is simple and convenient, advantage with low cost; And the loss of electric pump mechanical efficiency is little, and the life-span of thrust structure is long.
