Abstract
The utility model relates to the technical field of water pumps, in particular to a wiring-free device of a novel sewage pump, which is characterized by comprising a wiring pipe fitting, a motor cover, a motor casing, a motor stator part, a motor rotor part, a motor shaft, rotary shaft internal-wrapped framework lip-shaped seal, mechanical seal, an impeller, a pump body and a base plate. No position for mounting a wiring plate is arranged between the motor cover and the motor casing, and the structure is more compact by omitting one part, but insulation among phases and between each phase and the motor casing needs to be effectively performed in wiring due to the fact that a cable is directly wired with a stator winding 8, and precaution should be further taken to prevent the cable from contacting with a stator iron core when the motor cover is mounted. The wiring-free device of a novel sewage pump has the advantages that 1 traditional design with mounting of the wiring plate is replaced by the structure without mounting of the wiring plate, and the shortcomings of the traditional design with mounting of the wiring plate are overcome, 2 the performance of the pump is changed, and the efficiency and stability of the pump are improved, and 3 materials used for the pump body are greatly reduced, and the service life of the pump is prolonged.
Description
Technical field
The utility model relates to the pump technology field, especially a kind of novel pollution discharge pump exempt from termination.
Background technique
The tradition pollution discharge pump is provided with the design of dress wire board, and compressive resistance compares relatively poor, in the time of in being in the high-pressure work environment, can cause wire board to break, thereby makes the motor electric leakage lose efficacy, thereby damages the pump housing; And work for a long time has leakage situation and takes place, and has directly influenced the working efficiency of pump.
Summary of the invention
The tradition submersible pump has the design of dress wire board between motor cover 4 and motor casing 7, compressive resistance compares relatively poor, in the time of in being in the high-pressure work environment, can cause wire board to break, thereby makes the motor electric leakage lose efficacy, thereby damages the pump housing.
A kind of novel pollution discharge pump exempt from termination, its feature comprises: bag framework lip-shaped sealing 12, mechanical seal 15, impeller 19, the pump housing 20, chassis 21 in wiring pipe fitting 1, motor cover 4, motor casing 7, motor stator parts 8, motor rotor part 9, motor shaft 10, the running shaft.Do not establish the place of dress wire board between described motor cover 4 and the motor casing 7, cable and staor winding 8 direct wiring, to note during wiring carrying out phase and phase, and electric machine casing 7 between insulate; During dress motor cover 4, do not make cable run into rotor iron core 9.
The utility model is except removing wire board, and its beneficial effect is: 1. replaced tradition that the design of dress wire board is arranged with arming wire board structure, had the drawback 2. of dress wire board design to change pump performance thereby solved tradition, improved the efficient and the stability of pump.3. greatly reduce the material of using of the pump housing, prolong the working life of pump.

Fig. 1 is the utility model general structure schematic representation
Embodiment
The utility model has been removed the dress wire board, and design has solved the place of not adorning wire board between motor cover 4 and the motor casing 7 by self special internal structure, has lacked a part and has made structure compactness more.But cable is noted during with staor winding 8 wiring: phase and phase, and electric machine casing 7 between insulate and will carry out; During dress motor cover 4, note more not making cable run into rotor iron core 9.Tradition has breaking of dress wire board design and leaks drawback, thereby has improved the working life and the working efficiency of pump, has reduced maintenance cost.
