Abstract
Provided is a motor rotor paint trickling technology. The processing steps are listed as follows: preheating is performed before trickling paint, and then a paint trickling phase starts; after the paint trickling phase ends, preheating is performed again; and finally gelling and solidification are performed. The motor rotor paint trickling technology relates to the technical field of paint trickling in a motor manufacturing process, and particularly relates to the motor rotor paint trickling technology. Temperature jumps in the preheating process, the paint trickling process, and the gelling and solidification processes are reduced so that the paint absorption efficiency is facilitated. After the paint trickling process, the insulating effect is strengthened and the service life of the motor rotor is prolonged.
Description
Technical field
The present invention relates to dripping in the motor manufacture process and paint technical field, particularly relate to a kind of technique for painting electric machine rotor.
Background technology
It is very important in the rotor manufacture process that rotor drips paint, because rotor is operated in while running up state, temperature is very high, need to wrap japanning at the rotor enamelled wire is reinforced and is increased insulation property, once it is bad that rotor drips the effect of paint, can directly affect the useful life of rotor or even motor.At present, general rotor technique for painting, be all directly rotor to be transported to the thermal treatment zone to carry out preheating, drips paint after preheating and operate, and while dripping paint, easily produces bubble on rotor, reduced a paint quality of rotor; Directly carry out gel and curing operation after dripping paint, in whole process, temperature gradient is excessive, has affected the absorption efficiency of paint.
Summary of the invention
Purpose of the present invention will be to provide a kind of technique for painting electric machine rotor, and it is existing above not enough that it can solve existing rotor technique for painting.
The object of the present invention is achieved like this: a kind of technique for painting electric machine rotor is characterized in that: procedure of processing is as follows:
1), drip the front preheating of paint:
The preheating zone temperature of trickle impregnation machine is arranged on to 127-136 ℃, and be 38-42 minute warm-up time altogether.
2), drip paint:
Jiang Diqi district temperature setting is set to 25 ℃-45 ℃.
3), drip the rear preheating of paint:
The preheating zone temperature of trickle impregnation machine is arranged on to 127-136 ℃.
4), gel and curing:
The gelling temp of trickle impregnation machine is arranged on to 127 ℃-136 ℃, and gel time is 12-16 minute; Trickle impregnation machine the first curing temperature is arranged on 137 ℃-146 ℃; Trickle impregnation machine the second curing temperature is arranged on 152 ℃-161 ℃, and be 44-52 minute curing time altogether.
Curing in step of the present invention (4) comprises that first solidifies and second solidify.
The present invention reduced the temperature difference in whole technique for painting process, is conducive to the absorption to paint, improved the quality that rotor drips paint, increased the useful life of rotor.
Embodiment
Below by embodiment, the invention will be further described.
Embodiment
Before dripping paint: the preheating zone temperature setting of trickle impregnation machine is set to 130 ℃, can make the moisture rapid evaporation of rotor winding and iron core, axle, rotor is obtained fast and drip suitable temperature of paint stage; Can better reduce the viscosity of paint, make paint more easily infilter the rotor winding; After dripping paint, gel with curing before: the preheat temperature of trickle impregnation machine is set to 130 ℃, can make rotor through obtaining more suitably temperature value after the Di Qi district, the temperature jump of both having avoided rotor You Diqi district to enter into gel and curing area raises and causes that dripping enamelled coating ftractures, better guaranteed that again rotor makes the rotor line bag obtain stronger rigidity at gel and cure stage, stablizes every circle coil; After dripping paint, the first curing temperature is set to 140 ℃, and the second curing temperature is arranged on 155 ℃, and insulating varnish is fully curing, and stronger rigidity is arranged.Compared with the existing technology, the present invention is in technique for painting electric machine rotor, after preheating after adopt dripping before paint preheating and dripping paint, gel, first solidifies and second solidifies, make rotor temperature difference in whole technique for painting little, reduced the temperature jump of rotor at warm, droplet paint process, gel and solidification process, make rotor higher to the absorption efficiency of paint, after a paint, insulation effect is better, extends the useful life of rotor.
