Abstract
The utility model provides a motor stator for an electric submersible pump. In order to overcome the defect that the heat resisting temperature of a motor stator for the prior electric submersible pump is low because the motor stator uses the epoxy resin as the insulating material, the utility model comprises a slot insulation(1), electromagnetic wires(2) and insulating paint(3), wherein the slot insulation(1) wraps the electromagnetic wires(2), and the gap between the inside of the slot insulation(1) and the electromagnetic wires(2) is filled with the insulating paint(3) which are of polyester-imide impregnating varnish. The motor stator has the advantages of high level of high temperature resistance, good insulating performance and low manufacturing cost.
Description
Affiliated technical field
The utility model relates to a kind of oil production equipment submersible electric pump, especially a kind of submersible electric pump motor stator.
Background technology
The motor of submersible electric pump is prime mover of mechanical oil recovery equip ment submersible electric pump.After the submersible electric machine with oil stator winding installation finishes in process of production, exist micropore and thin layer gap owing to form the coil of winding, the moisture absorption easily makes the insulation property and the heat conductivility variation of stator; Owing to there is the space, oxygen or other corrosive gass and insulating material contact area increase, and easily make insulating material oxidation or corrosion; Under electric field action, the easy ionization of the gas in the insulating material causes insulation breakdown.The effect of insulation processing is exactly that contained moisture in the insulating material is driven away, make insulating material fill up all spaces of internal layer and covering surfaces, with moisture resistance, decay resistance, electric property, heat-resisting and heat conductivility, mechanical performance and the chemical stability etc. that improve winding.For fear of these problems, present submersible electric machine with oil stator adopts the casting epoxy resin form to carry out insulation processing more, adopts the method that the heat resisting temperature grade of motor is reduced, and has limited the application of Electric Submersible Pump Unit in high temperature well.
The utility model content
In order to overcome existing submersible electric pump motor stator employing epoxy resin is insulating material, the deficiency that its heat resisting temperature is low, the utility model provides a kind of submersible electric pump motor stator, this submersible electric pump motor stator temperature resistant grade up to 150 ℃, insulating properties reaches 2000M Ω.
The technical scheme that its technical problem that solves the utility model adopts is: the submersible electric pump motor stator comprises slot liner, electromagnetic wire, insulating varnish, slot liner parcel electromagnetic wire, insulating varnish is filled up in the slot liner and the space between the electromagnetic wire, and insulating varnish is the polyester-imide impregnating varnish.
The beneficial effect of the utility model submersible electric pump motor stator is temperature resistant grade height, good insulation preformance, production cost decline.
Description of drawings
Fig. 1 is the utility model submersible electric pump motor stator profile.
Fig. 2 is the local enlarged diagram of the utility model.
Among the figure: 1. slot liner, 2. electromagnetic wire, 3. insulating varnish.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
To the utility model submersible electric pump motor stator, comprise slot liner 1, electromagnetic wire 2, insulating varnish 3, slot liner 1 parcel electromagnetic wire 2, insulating varnish 3 is filled up in the slot liner 1 and space between the electromagnetic wire 2, and insulating varnish 3 is the polyester-imide impregnating varnish.
The polyester-imide impregnating varnish has suitable viscosity and higher solids content, is convenient to fill the space, reduces its moisture absorption; The thick-layer quick solidifying, drying property is good; Have good electric property, anti-moisture performance and heat resistance, and oil resistant and stable chemical performance; Temperature resistant grade can reach 150 ℃, whenever relatively insulate more than 2000M Ω.
Claims (1)
1. submersible electric pump motor stator, comprise slot liner (1), electromagnetic wire (2), insulating varnish (3), slot liner (1) parcel electromagnetic wire (2), insulating varnish (3) is filled up in the slot liner (1) and the space between the electromagnetic wire (2), and it is characterized in that: insulating varnish (3) is the polyester-imide impregnating varnish.
