Abstract
The utility model discloses a compound frame of stainless steel immersible pump motor, this frame include stainless steel shell and inside stator core, still include the carbon steel inner shell of arranging the stainless steel shell in through the hot pressing mode, and stainless steel shell thickness reduces, carbon steel inner shell outer wall and stainless steel shell inner wall in close contact with, the weld part welding at the upper and lower both ends of carbon steel inner shell and stainless steel shell. The utility model not only can not reduce the motor strength, but also can improve the heat dissipation performance; the heating value is reduced, the loss is reduced, and the motor efficiency is improved. The motor base with the composite structure reduces the using amount of expensive austenitic stainless steel materials, saves resources and greatly reduces the product cost.
Description
Technical field
The utility model relates to electric machine stand, particularly a kind of compound support of stainless steel submersible pump motor.
Background technology
Present big-and-middle-sized stainless steel submersible pump is not long with the useful life of motor, motor windings burns out easily, through long-term careful discovering repeatedly, its reason is because the electric machine stand housing uses is stainless steel, directly causes burning out of motor windings because causing property of stainless steel is poor, heat radiation is bad.Austenitic stainless steel (as models such as 304,316) is the main material that is applied to the stainless steel submersible pump motor at present, its good corrosion resistance, cost are moderate, can satisfy the application that the overwhelming majority has corrosive liquid environment, but its thermal conductivity is very low, be about 1/3 of carbon steel, just because of the bad reason of heat conduction, the long-time full-load run of motor certainly will cause the motor cavity local overheating, damages motor windings.Present solution has following several: one, strengthen unshakable in one's determination, overstriking winding material, though can make winding be difficult for being burnt out, increased the cost of product greatly; Two, reduce frame shell thickness or replace austenitic stainless steel to solve heat dissipation problem with the good material of other thermal conductivity, but large and middle size motor needs enough intensity, the reduction that reduces or cause undoubtedly with the good material replacement austenitic stainless steel of other thermal conductivity its intensity of frame shell thickness.Such scheme all has weak point, so need the electric machine stand of a kind of intensity height, perfect heat-dissipating.
The utility model content
The purpose of this utility model is to disclose a kind of simple in structure, the compound support of the stainless steel submersible pump motor of intensity height, perfect heat-dissipating.
For reaching the foregoing invention purpose, the technical scheme that is adopted is: a kind of compound support of stainless steel submersible pump motor, this support comprises stainless steel casing and inner stator core thereof, also comprise by hot pressing mode and place carbon steel inner casing in the stainless steel casing, and stainless steel casing thickness reduces, carbon steel inner casing outer wall closely contacts with the stainless steel casing inwall, the weld part welding at the two ends up and down of carbon steel inner casing and stainless steel casing.
The utility model changes stainless steel casing thin, be with the good carbon steel inner casing of thermal conductivity simultaneously, the shell wall formation face contact that contacts between carbon steel inner casing and the stainless steel casing, heat in the motor passes to the stainless steel casing heat radiation by the good carbon steel inner casing of thermal conductivity, make motor intensity not only can not reduce, improved thermal diffusivity simultaneously.As everyone knows, improve efficiency of motor and fall low magnetic density, electric close nothing more than, reduce loss, reduce caloric value, the utility model is for two-pole machine, motor stator yoke portion magnetic flux is higher, add that a thicker mild steel inner casing has equaled to increase the area of stator core yoke portion, yoke portion magnetic flux decreases, and has reduced caloric value, reduce loss, thereby improved electric efficiency.The electric machine stand of this composite construction has reduced the consumption of expensive austenitic stainless steel material, economizes on resources, greatly reduced product cost.
Description of drawings
Fig. 1 is first kind of structural representation of the utility model;
Among the figure: 1-stator core, 2-stainless steel casing, 3-carbon steel inner casing, 4-weld part.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, a kind of compound support of stainless steel submersible pump motor, this support comprises stainless steel casing 2 and inner stator core 1 thereof, also comprise by hot pressing mode and place carbon steel inner casing 3 in the stainless steel casing 2, and stainless steel casing 2 thickness reduce, carbon steel inner casing 3 outer walls closely contact with stainless steel casing 2 inwalls, and carbon steel inner casing 3 welds with the weld part 4 at the two ends up and down of stainless steel casing 2.
