Abstract

The utility model relates to the field of machinary, especially, relate to bright pipe dive three -phase asynchronous motor. Contain stator towards piece, it is bright intraductal that the stator is located finish rolling towards the piece, still contains the clamping ring of both sides, and the clamping ring contains the annular structure in hole for the middle part, ring dress structure and the bright inside pipe wall welding of finish rolling, and the stator is fixed through two clamping rings towards piece both sides. Adopt as above technical scheme the utility model discloses, there is following beneficial effect for prior art: adopt accurate bright pipe be one kind through one kind after the cold rolling processing high -accuracy steel pipe material. Because accurate bright intraductal outer wall does not have the oxide layer, does not bear the no leakage of high pressure, high accuracy, high glossiness, clod wash are indeformable, the flaring, flatten advantage such as aletus.

Description

Seamless pipe submersible three phase asynchronous motor

Technical field

This utility model is related to mechanical field, more particularly, to seamless pipe submersible three phase asynchronous motor.

Background technology

Traditional submersible asynchronous motor casing is welded using roll of steel plate to be made.The shortcoming that processing exists：1. need special Plate bending machine；2. it is welded casing and manufacture high labor intensive, low production efficiency；3. casing produces welding stress, impact through welding The linearity of motor and performance, eliminating welding stress wastes time and energy.4. appearance complex treatment process is wanted it is difficult to reach technique Ask.5. the shortcomings of weld seam is subject to inner easy to crack.

Utility model content

The purpose of utility model：In order to provide a kind of effect more preferable seamless pipe submersible three phase asynchronous motor, concrete mesh See the multiple substantial technological effects being embodied as part.

In order to reach as above purpose, this utility model adopts the following technical scheme that：

It is characterised in that comprising stator punching, stator punching is located at finish rolling light to seamless pipe submersible three phase asynchronous motor In bright pipe, also comprise the trim ring of both sides, trim ring is the circulus that middle part comprises hole, ring assembling structure and finish rolling light inside pipe wall weld Connect, stator punching both sides are fixed by two trim rings.

The further technical scheme of this utility model is, described finish rolling seamless pipe both sides comprise two openings, side respectively Opening comprise seam ring, the opening of opposite side comprises lower seam circle.

The further technical scheme of this utility model is, described finish rolling seamless pipe Nell wall comprises groove, stator punching In groove.

Using this utility model of as above technical scheme, have the advantages that with respect to prior art：Using precise light Bright pipe is a kind of a kind of high-accuracy tube material after cold-rolling treatment.Due to accurate seamless pipe inside and outside wall non-oxidation layer, Bear high-pressure non-leakage, in high precision, best bright finish, clod wash be indeformable, enlarging, the advantages of flatten free from flaw.

Brief description

In order to further illustrate this utility model, it is further illustrated below in conjunction with the accompanying drawings：

Fig. 1 is utility model structural representation；

Wherein：1. go up seam ring；2. finish rolling seamless pipe；3. trim ring；4. stator punching；5. descend seam circle.

Specific embodiment

Below in conjunction with the accompanying drawings embodiment of the present utility model is illustrated, embodiment is not constituted to limit of the present utility model System：

It is characterised in that comprising stator punching, stator punching is located at finish rolling light to seamless pipe submersible three phase asynchronous motor In bright pipe, also comprise the trim ring of both sides, trim ring is the circulus that middle part comprises hole, ring assembling structure and finish rolling light inside pipe wall weld Connect, stator punching both sides are fixed by two trim rings.The technique effect of the essence that the technical scheme at this place is played and its realization Process is as follows：It is a kind of a kind of high-accuracy tube material after cold-rolling treatment using accurate seamless pipe.Due to precision Seamless pipe inside and outside wall non-oxidation layer, bear high-pressure non-leakage, in high precision, best bright finish, clod wash be indeformable, enlarging, flatten and no split The advantages of seam.

Described finish rolling seamless pipe both sides comprise two openings respectively, and the opening of side comprises seam ring, the opening of opposite side Mouth comprises lower seam circle.The technique effect of the essence that the technical scheme at this place is played and its process of realizing are as follows：Existing skill Art adopts steel plate to be welded, and needs special plate bending machine that the steel plate of lower honest material is rolled into tubular, is attached on the iron core having press-fited, uses Special fixture banding, welder molding.Need after the completion of welding manually to tap elimination welding stress.Using seamless pipe manufacture Iron core is loaded after only needing to common sawing machine blanking.Eliminate plate bending machine and hanging device and hoop using this utility model The tight operation such as special fixture and welding, has saved manufacturing equipment, has shortened manufacturing process, reduced labor intensity, reached and carried The high purpose of labor efficiency and energy-conservation.

Groove is comprised, stator punching is located in groove in described finish rolling seamless pipe Nell wall.The technical scheme at this place is risen To the technique effect of essence and its process of realizing be as follows：Stator punching can be placed in groove, will not displacement, fixing effect Really good.

1. seamless pipe geometric accuracy is high, can meet use requirement without machining.

2. load performance is good, and casing is not easy to crack, is unlikely to deform.3. do not need to be surface-treated.

Preferably, trim ring comprises circle extruding rubber outwardly, can close rapidly and operate.

In a creative way, each effect above is individually present moreover it is possible to complete the combination of the above results with a nested structure.

It is clear that the technique effect that above structure is realized is realized, and discounting for additional technical scheme, this patent title is also It can be a kind of Novel electric pump assembling structure.In figure not shown part details.

It should be noted that multiple schemes that this patent provides comprise the basic scheme of itself, separate, not mutually Restriction, but it can also be mutually combined in the case of not conflicting, and reach multiple effects and jointly realize.

Of the present utility model ultimate principle, principal character and of the present utility model advantage have been shown and described above.Ability The technical staff in domain it should be recognized that this utility model is not restricted to the described embodiments, described in above-described embodiment and description Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, this utility model also can There are various changes and modifications, these changes and improvements both fall within claimed scope.
