Description
Technical field
The present invention relates to a kind of motor windings processing technology field, particularly a kind of electric motor winding end is coated with the processing technology of silicone rubber resina.
Background technology
In the present motor production process,, just get into following one assembling procedure normally with after the motor windings stator core dipping lacquer drying.
The motor that such processing technology is produced, in use breaking down maximum is that winding puncture, short circuit in winding, winding are opened circuit, winding burns out etc., these all belong to the electrical machine insulation problem.Motor is in startup, operation and stopped process; Insulating material will bear the impact of electric and magnetic oscillation and mechanical oscillation; Also to receive the etch of etchant gas in moisture in the air, dust, salt fog and the operational environment or drop; And stand to move the aging of time heating condition, so the length of electrical machinery life depends primarily on the insulation quality of motor windings.
Summary of the invention
The purpose of this invention is to provide a kind of motor windings processing technology,, overcome above-mentioned shortcoming of the prior art through electric motor winding end is coated with silicone rubber resina.
For realizing above-mentioned purpose, the present invention realizes through following technical scheme:
A kind of motor windings processing technology may further comprise the steps:
(1) prepares: after winding stator core paint-dipping process is accomplished, will have the winding stator core to crouch and put;
(2) gluing: 8012 binding agent A, 8012 binding agent B and diluent are mixed with silicone rubber resina; Manner of formulation is: 8012 binding agent A and 8012 binding agent B add the diluent that is no more than total weight 5 percent, the silicone rubber resina that obtains after the preparation again by weight 1:1; Spread upon the winding overhang of winding stator core equably with painting brush; The winding overhang inside and outside all will be smeared complete, collides adhesion between winding overhang of avoiding in the operating process smearing and the end, causes scaling;
(3) cartonning: hang in the dipping lacquer cage having smeared the winding stator core, again the dipping lacquer cage is hung in the baking oven chassis, then chassis is pushed the UA electric drying oven with forced convection, close good dry chamber door;
(4) drying: drive air blast and heater successively, dry the temperature inside the box is set at 120 ℃, be incubated 2 hours;
(5) cooling: close heater, dry after 30 minutes, turn off air blast again, release chassis, the winding stator core is taken out;
(6) check: the winding overhang after getting well with brush is dry; Inspection: the glued membrane color should be consistent, and hand touches glued membrane should be tack-free and flexible slightly, and epidermis does not have crackle, wrinkle and shelling; The glued membrane that hangs on the iron core silicon steel sheet cylindrical should be polished totally, prevents to influence shell.
The beneficial effect of motor windings processing technology of the present invention is:
(1) anti-moisture performance of raising motor.Any insulating material more or less absorbs moisture always in malaria; The performance of insulating material will significantly descend like this; After winding overhang is coated with silica gel, can make the winding table face form the glued membrane of the smooth free of pinholes of one deck, air and insulating barrier are isolated; Significantly reduce moisture go into to soak, thereby improve the humidity resistance of motor;
(2) thermal endurance and the thermal conductivity of raising motor.After motor insulation material was heated, its inside just decomposited lower-molecular substances such as gas hydrone, and took place with oxidation; Material property changes, and insulating material is aging, after winding overhang is coated with silica gel; Insulating material and air insulated; The speed of oxidation greatly reduces, and under same useful life, the serviceability temperature of motor can improve.In like manner, the thermal conductivity of motor also is improved;
(3) electric property and the mechanical performance of raising motor.After winding overhang is coated with silica gel; Firm again one deck glued membrane outside paint film; Moisture be difficult for to get into, so insulation resistance all increases with puncture voltage, has enough mechanical strengths to resist the vibrations and the stress of outside; And bear the mechanical impact in the motor assembling process, thereby avoided the damage of mechanism.Because when insulating material is heated, material can change, and decomposes to discharge gas, moisture and carbonaceous; Material just loses pliability, but through behind the brushing silica gel, can delay greatly in processes such as hot cracking down, hydrolysis; The mechanical flexibility of material is able to long-term maintenance, and the formed glued membrane of silica gel has certain elasticity and adherence down hot simultaneously, and the adhesion between the material is strengthened; Form a firm integral body, promoted the intensity of system greatly;
(4) resistance to chemical corrosion of raising motor.After winding overhang is coated with silica gel; Can prevent that insulating material from contacting with the direct of the chemicals that is corrosive with motor all kinds of solvents on every side; Can improve motor chemically-resistant Stability of Substance like this,, cut off and the contacting of extraneous foreign matter because insulation is sealed by glued membrane; Improve the stability of winding overhang, and had mildew-resistant, anti-greasy dirt, performance such as fire-retardant.
