Abstract
The utility model provides a tandem type thrust protector which is designed for solving the problems of a great reverse axial force and the early failure of an anti-thrust bearing lying in the prior screw pump. The thrust protector comprises a casing and a shaft arranged inside the casing. The shaft passes through the casing, one end of the shaft is connected with a screw pump, and the other end of the shaft is connected with a submersible planet gear reducer through a connecting flange; therein, a tandem shaft liner arranged on the circumference of the shaft consists of two or more than two sub shaft liners which are connected in series; the tandem shaft liner is fixedly connected with the casing. The tandem type thrust protector which is arranged between the screw pump and the submersible planet gear reducer can conduct the axial force stage by stage to the casing and the connecting flange through the multistage tandem shaft liner to neutralize the axial force, and a spline housing on one end of the shaft supplies an output force completely free of the axial force. The tandem type thrust protector can fundamentally solve the problem of the axial force in an electric submersible screw pump system with a simple structure, a small size, little maintenance, a strong anti-thrust capability, and a long service life.
Description
Technical field
The utility model relates to a kind of thrust force protection device, particularly relates to a kind of tandem thrust force protection device.
Background technique
The electric submersible screw pump system has a kind ofly produced, has used very long a period of time at home and abroad.To be that screw pump is counter push away that axial force is big, the problem of thrust bearing early failue to the principal element of this electric submersible screw pump of puzzlement system development at present, therefore is badly in need of developing the thrust force protection device of a kind of suitable electric submersible screw pump system
The model utility content
At defective of the prior art and deficiency, the purpose of this utility model be propose a kind of simple in structure and can be applicable to the dive tandem thrust force protection device of screw rod system of electricity.
In order to achieve the above object, the utility model proposes a kind of tandem thrust force protection device, comprising: housing and be arranged at axle in the housing, described runs through described housing, and an end of axle is connected with screw pump, and the other end is connected with latent oily plane table thermoconductivity meter by adpting flange;
Wherein, the periphery of described axle is provided with the series connection axle sleeve, and described series connection axle sleeve comprises that two or two sub-axle sleeves are in series; Described series connection axle sleeve is fixedlyed connected with described housing.
The axial force of screw pump is transferred on the axle of this tandem thrust force protection device like this; and by axle conduct axle sleeve to the series connection; and output on housing and the adpting flange by series connection axle sleeve classification; to offset axial force; so just can just not have axial force fully, solved effectively that existing screw pump is counter to push away that axial force is big, the problem of thrust bearing early failue from the power of the other end of axle output.
Preferred as technique scheme, an end of described axle are provided with spline housing with as output terminal.
Preferred as technique scheme, an end of described axle is connected with the shaft drive of described screw pump by connecting body.
Preferred as technique scheme, the periphery of described axle is provided with inducer, and described inducer is connected with described axle by spline thinks that described axle provides circulating oil path to ensure lubricating and cooling off of described series connection bearing.
The utility model proposes a kind of tandem thrust force protection device, at existing screw pump existingly instead push away that axial force is big, the problem of thrust bearing early failue and designing, comprise: housing and be arranged at axle in the housing, described axle runs through described housing, and an end of axle is connected with screw pump, and the other end is connected with latent oily plane table thermoconductivity meter by adpting flange; Wherein, the periphery of described axle is provided with the series connection axle sleeve, and described series connection axle sleeve comprises that two or two sub-axle sleeves are in series; Described series connection axle sleeve is fixedlyed connected with described housing.The tandem thrust force protection device that the utility model proposes; be arranged between screw pump and the latent oily plane table thermoconductivity meter; plural serial stage axle sleeve by the axle periphery is transmitted to axial force on housing and the adpting flange step by step; offsetting axial force, and provide the ouput force that does not have axial force fully by the spline housing of an end of axle.The tandem thrust force protection device that the utility model proposes is simple in structure, volume is little, keep in repair less, thrust capacity is strong, the life-span is long, has fundamentally solved the axial force problem of electric submersible screw pump system.
Description of drawings
Fig. 1 is the utility model preferred embodiment structural representation;
Reference character is among the figure:

Embodiment
Below in conjunction with accompanying drawing the utility model is made and to further specify.
The utility model preferred embodiment comprises housing 3 and is arranged at axle 1 in the housing 3 as shown in Figure 1,
Described axle 1 runs through described housing, and an end of axle 1 is connected with screw pump by connecting body 7, and the other end is connected with latent oily plane table thermoconductivity meter by adpting flange 5.The periphery of axle 1 is provided with multistage series connection axle sleeve 2, and series connection axle sleeve 2 is in series by two or more sub-axle sleeves, and the progression of series connection axle sleeve 2 can be according to the size setting of actual axial force, and those skilled in that art are appreciated that at this and do not relate one by one.
Series connection axle sleeve 2 is fixedlyed connected with housing 3, is transmitted on housing 3 and the adpting flange 4 so that the axial force of axle 1 is decomposed step by step.Do not have axial force fully by spline housing 5 ouput forces.As shown in Figure 1, the periphery of axle 1 is provided with inducer 6, ensures the lubricated and cooling of series connection bearing 2 so that circulating oil path to be provided.Inducer 6 can be designed as and axle sleeve 2 adjacency of connecting, and also can be designed as the outside that is socketed in series connection axle sleeve 2, and set-up mode can be for multiple, and those skilled in that art are appreciated that at this and do not give unnecessary details one by one.
The foregoing description is just made the utility model and being illustrated, and understand to make things convenient for those skilled in that art, but protection domain of the present utility model is not limited only to this.The improvement that those skilled in that art make according to the utility model is all within protection domain of the present utility model.
