Abstract
The utility model relates to the underwater electric motor of the shell of the machine producing the steel pipe without gap, which comprises an upper end cover, an O-type sealing ring, the shell of the machine producing the steel pipe without gap, the stator iron core of a winding, a rotator assembly, a lower end cover, a pump cover and a movable sealing device. The utility model is characterized in that the upper end cover and the lower end cover are directly connected by a bolt passing through the hole gap of the stator iron core of the winding. The thin-wall shell of the machine producing the steel pipes without the gap is adopted. The inner wall and the outer wall do not need to be processed and no air pressure test is required. The utility model has simple manufacture technology, good radiation effect, stable and reliable work, beautiful appearance, light weight, low cost, economy and practicality. The waste product basically does not exist and a connecting flange is removed.
Description
The utility model relates to a kind of motor, particularly a kind of seamless steel pipe casing submersible motor.
At present, the casing of submersible motor, end cap all adopt cast member, the processing of will demanding perfection of inwall and end face, and unfavorable heat radiation, functional reliability is poor, and must be by gas pressure test, and qualification rate is low.Upper and lower end cap is connected with casing by flange, has increased weight, the cost height.
The purpose of this utility model is in order to overcome above-mentioned weak point, and provides a kind of manufacturing process simple, good heat dissipation effect, and working stability is reliable, and is in light weight, the seamless steel pipe casing submersible motor that cost is low.
The purpose of this utility model is achieved in that seamless steel pipe casing submersible motor comprises upper end cover O RunddichtringO, seamless steel pipe casing, winding stator core, rotor portions dress, bottom end cover, pump cover dynamic sealing device are arranged, and it is characterized in that by the hole that bolt passes in the winding stator core upper end cover directly being connected with bottom end cover.
Fig. 1 is the utility model structural representation.
Now illustrated embodiment is made detailed description to the utility model in conjunction with the accompanying drawings.
Seamless steel pipe casing submersible motor comprises upper end cover 1, O RunddichtringO 2, seamless steel pipe casing 3, have that winding stator core 4, rotor portions adorn 5, bottom end cover 6, pump cover 7, dynamic sealing device 8 thin-wall seamless steel pipe casings 3 with have winding stator core 4 to press-fit to be integral, after bolt 9 passes hole in the winding stator core 4 and is tightened in the upper end cover 1, reinstall that rotor portions adorns 5, bottom end cover 6 is screwed into nut and by bolt 9 upper end cover 1 directly is connected with bottom end cover 6, dynamic sealing device 8, pump cover 7 are installed at last, and each connected components stop portion is placed with O RunddichtringO 2.
The utility model is owing to adopt above design, and thin-wall seamless steel pipe casing, inside and outside wall need not processing, also do not carry out gas pressure test, and manufacturing process is simple, good heat dissipation effect, and working stability is reliable, and is specious, do not have waste product substantially.Removed adpting flange, the hole that is passed in the winding stator core by bolt directly is connected upper end cover with bottom end cover, and in light weight, cost is low, and is economical and practical.
