Abstract
The utility model relates to a centrifugal electric submersible pump with double impellers, which is assembled by a motor and an impeller pump body connected to an output shaft of the motor. The utility model is characterized in that the impeller pump body of the electric submersible pump is provided with two impellers (5) which are respectively provided with a guide wing disk (6) and are fixed on a flat key (17) of a motor shaft through fastening bolts of the other end of the motor shaft; the other guide wing disk, a cover body of the pump body, a water discharge opening (10) and a fixing flange (11) are made into integration; the periphery of the pump body (7) is provided with four connecting pull plates (8) which are respectively fixed on the flange (11) of the pump body and a bottom plate (18) of the pump body by bolts; a bolt of the flange is welded with a lifting ring (12). The centrifugal electric submersible pump has large water output and high lifting ranges.
Description
Technical field:
The utility model relates to the water discharge technology field, a kind of double-impeller centrifugal Submerged Motor Pumps.
Background technique:
At present, the centrifugal and submersible pump device mainly is and two kinds of structures of turbine-type, the scroll casing type submersible pump is not provided with the guide vane dish, and the guide vane dish of turbine-type submersible pump is arranged on the outside of impeller, the output power of motor is limited, and under certain power of motor, the pressure of its water and lift will be realized by the diameter that increases impeller, but the diameter of well is limited, has also just limited the lifting of pump head; Especially in the lower place of water table ratio, wanting to get the higher well of a bite lift, is a problem that is difficult to solution.
Summary of the invention:
For overcoming the existing centrifugal water pump problem that pressure is little, lift is short in using, the purpose of this utility model provides a kind of double-impeller centrifugal Submerged Motor Pumps, makes its water-outlet quantity big, and the lift height is to satisfy people's living needs.
For achieving the above object, the utility model adopts following technological scheme:
Described double-impeller centrifugal Submerged Motor Pumps is assembled by the bilobed wheel pump housing that connects on motor and the motor output shaft; The bilobed wheel pump housing has two impellers, and two impellers respectively are provided with a guide vane dish, and two impellers are fixed on the flat key of motor shaft by the clamping bolt of the motor shaft the other end, and cover body, drain opening and the fastening flange of another guide vane dish and the pump housing are made as an integral body; The pump housing outer is with four and connects arm-ties, arm-tie is fixed on the base plate of the flange plate of the pump housing and the pump housing with bolt respectively; On the bolt of flange plate, be connected to suspension ring.
Owing to adopt aforesaid technological scheme, the utlity model has following superiority:
1, to the improvement of guide vane dish and impeller, make that under the constant situation of pump housing housing diameter dwindled the diameter of impeller loam cake, water flow increases, each grade impeller centrifugal force is increased, the current lift increases 1/3.
2, because the increase of current lift when the water pump of the same lift of design, can reduce the progression of pump, also just reduced the rate of fault and the manufacture cost of pump.
3, overall structure is that the pump housing and drain opening are fastenedly connected the multistage pump housing with the adpting flange arm-tie, makes the utility model compact structure, and modern design is attractive in appearance.
Description of drawings:
Fig. 1 is a double-impeller centrifugal Submerged Motor Pumps overall structure sectional view:
Fig. 2 is the blade partial sectional view of double-impeller centrifugal Submerged Motor Pumps impeller:
As shown in FIG.: the 1-motor, the 2-motor housing, the 3-bearing, the 4-pump shaft, the 5-impeller,
6-guide vane dish, the 7-pump housing, the 8-pump housing connects arm-tie, the 9-water sucking mouth, the 10-drain opening,
The 11-adpting flange, the 12-suspension ring, the 13-blade, 14-blade exposed parts, the 15-axis hole,
16-water dumping groove, 17-connects flat key, 18-pump housing base plate.
Embodiment one:
As shown in fig. 1: this double-impeller centrifugal Submerged Motor Pumps is assembled by the bilobed wheel pump housing that connects on motor and the motor output shaft; The bilobed wheel pump housing has two impellers (5), two impellers respectively are provided with a guide vane dish (6), two impellers are fixed on by the clamping bolt of the motor shaft the other end on the flat key (17) of motor shaft, and the cover body of another guide vane dish and the pump housing, drain opening (10) and fastening flange (11) are made as an integral body; The pump housing (7) outer is with four and connects arm-ties (8), arm-tie is fixed on the base plate (18) of the flange plate (11) of the pump housing and the pump housing with bolt respectively; On the bolt of flange plate, be welded with suspension ring (12).
When electric motor starting, impeller coaxial rotation in the pump housing, just (9) enter impeller (5) to water from the water sucking mouth at this moment, under the drive of blade (13), water just throws away from blade exposed parts (14), under the effect of guide vane dish (6), current enter rapidly in the next stage impeller, through the pressurization of impeller, big water quantity, high-lift current flow out from drain opening, enter in the pipeline, for people's use of living.
