Abstract
The utility model relates to an under water pump with a slim shaft, which belongs to an under water pump, particularly the under water pump with a slim shaft and the under water pump with a slim shaft is unattacked and is used for transporting corrosive liquids which are without solid particles and is not easy to solidify. The utility model comprises a bottom board (6), a bearing bracket (4), an electric machine bracket (3), an electric machine (1), a pump hanging sling body (7) which is fixed below the bottom board (6) and is connected with a pump body (10) through a shaft sleeve wear ring (9), and the slim shaft (8) arranged in the pump hanging sling body (7), wherein the bearing bracket (4), the electric machine bracket (3) and the electric machine (1) are arranged on the bottom board (6); one end of the slim shaft (8) is connected with the electric machine (1) through a top bearing seat (13) and a shaft coupling (2), and the other end is connected with an impeller (11). The utility model is characterized in that a bearing seat (12) is arranged on the pump hanging sling body (7). The utility model effectively prolongs the service life of the under water pump with a slim shaft, the vibration of the pump is evidently reduced, the maintenance period is prolonged, so production can be stably carried out.
Description
Technical field
The utility model relates to a kind of Under Water Pumps, and particularly a kind of corrosion-resistant slender axles Under Water Pumps is used to carry the corrosive liquids that does not contain solid particle and be difficult for crystallization.
Background technique
At present the slender axles Under Water Pumps that uses in the oil field is in installing and using process, vibrate greatlyyer, and amplitude reaches 0.2mm, and not grow (the shortest 48 hours) running time the axle sleeve eccentric wear promptly takes place, damage of bearings, the fault of damage in impeller influences production normally.
The model utility content
Technical problem to be solved in the utility model is in order to overcome above-mentioned deficiency, to provide a kind of the vibration obviously to reduce, make production to be stablized the slender axles Under Water Pumps that carries out.
For solving the problems of the technologies described above, the technological scheme that the utility model adopted is: a kind of slender axles Under Water Pumps is provided, the bearing bracket, electric machine support and the motor that comprise base plate, base plate top, being fixed on pump that the base plate bottom is connected with the pump housing by the axle sleeve wear ring hangs outstanding body and is arranged on pump and hang slender axles in the outstanding body, one end of slender axles connects motor by top axle bearing, coupling, the other end connects impeller, and pump is hung outstanding body and is provided with bearing support.
Described slender axles Under Water Pumps, its bearing seat are hung the middle part of outstanding body in pump; The medium position of the outstanding body of original pump extension by axle is divided into two, on the outstanding body of pump extension, process adpting flange, other processes a bearing support and is used to install rolling bearing, after bearing support and pump are hung outstanding body flange and are connected, slender axles promptly are limited in the central position that pump is hung outstanding body, and its amount of deformation is limited in the 0.05mm.
Described slender axles Under Water Pumps is provided with a thrust bearing in its top axle bearing.
Described slender axles Under Water Pumps, its axle sleeve wear ring is made by stainless steel.
Described slender axles Under Water Pumps, the inlet of its pump housing is provided with filter screen.
Compared with prior art the beneficial effect that the utility model had is: because pump of the present utility model is hung the middle part of outstanding body bearing support is set, like this, slender axles form sight alignment between the spacing spring bearing at the drop-hanger bearing at top, middle part and pump housing sliding bearing restriction makes slender axles that the flexible deformation be taken place no longer easily, vibration obviously reduces, thereby prolongs its working life; Thrust bearing of the interior increase of top axle bearing can eliminate stress and alleviate bearing load; The axle sleeve wear ring changes by stainless steel to be made, and can improve assembly precision; Increase filter screen in pump inlet place and can remove impurity.Therefore, the utility model has effectively prolonged the working life of slender axles Under Water Pumpss, and the vibration of pump obviously reduces, and service cycle generally prolongs, and makes to produce to be stablized to carry out.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is done further detailed narration;
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
1 motor, 2 coupling, 3 electric machine supports, 4 bearing brackets, 5 thrust bearings, 6 base plates, 7 pumps are hung outstanding body 8 slender axles 9 axle sleeve wear rings 10 pump housings 11 impellers 12 bearing supports 13 top axle bearings
As shown in Figure 1, the fixedly connected bearing bracket 4 in the top of base plate 6, the fixedly connected electric machine support 3 in the top of bearing bracket 4, the fixedly connected motor 1 in the top of electric machine support 3; The fixedly connected pump in base plate 6 bottoms is hung outstanding body 7, and pump is hung outstanding body 7 and is connected with the pump housing 10 by axle sleeve wear ring 9, and pump is hung in the outstanding body 7 slender axles 8 are set, and an end of slender axles 8 connects motor 1 by top axle bearing 13, coupling 2, and the other end connects impeller 11.The outstanding body 7 of pump extension is divided into two by the medium position of axle, hangs on the outstanding body 7 at pump and processes adpting flange, and other processes a bearing support 12 and is used to install rolling bearing; After bearing support 12 and pump were hung outstanding body flange and be connected, slender axles 8 promptly were limited in the central position that pump is hung outstanding body 7, and its amount of deformation is limited in satisfying the needs that pump turns round fully in the 0.05mm (machining accuracy and bearing play).Slender axles 8 are between the spacing spring bearing and pump housing sliding bearing at the drop-hanger bearing at top, middle part, and the restriction of sight alignment makes slender axles 8 that the flexible deformation be taken place no longer easily, and vibration obviously reduces, thereby prolongs its working life.
