Abstract
Disclosed is far infrared heating furnace of motor windings. According to the far infrared heating furnace of the motor windings, the heating process is performed through resistance wires, the connection mode of the far infrared heating furnace of the motor windings is changed from 380-volt dual-delta-shaped mode into a dual-Y-shaped mode, so that voltage reduction and power consumption halving can be obtained; electric heating wire infrared agent and an adhesive which is mainly composed of 60% Fe.O3 and 35% Na2siO3 are directly painted on the resistance wires and silicic acid sheets to achieve a dual-radiation heating unit; polished thin aluminum plates with low light absorptivity and high light reflectivity cover the furnace chamber for reflective heat collection. The working process of the far infrared heating furnace of the motor windings comprises the steps of drying the motor windings by increasing the furnace temperature to 110-150 DEG C within half an hour to evaporate water inside the motor windings; after 2-3 hours, if the saturation value of an insulation resistor inside the furnace is higher than 5 megohms, decreasing the temperature to 80-70 DEG C; immersing the motor windings into 1032 varnish, then drying the immersed motor windings inside the furnace. The far infrared heating furnace of motor windings is energy-saving and time-saving, the whole process is shortened from 16 hours to 9 hours, the saturation value of the insulation resistor of the motor winding is detected to be more than 200 megohms, so that the voltage withstanding capacity is significantly improved.
Description
Technical field
The present invention relates to the FAR INFRARED HEATING stove of a motor winding, especially individual motor repair shop is more applicable.
Background technology
As everyone knows, the development of going at express speed along with the industrialization of the country, motor is more and more had place to show one's prowess, newly-built motor production line is wanted winding dipping lacquer, dry, aging or the motor that burns of motor in use is winding dipping lacquer again also, and traditional historical dipping paint of motor winding majority is with electric heating direct baking stove, especially individual motor repair shop, motor stator space after winding again, hang up the electric light of a high-power wattage, as dried with 100 watts of electric light heatings, as everyone knows, electric light is to be mainly luminous energy by electric energy conversion, borrow luminous some heat energy to remove to dry motor winding, this conventional equipment and method, the limited power resource of the country of waste greatly, it is current promotion low-carbon green environmental protection policy, the utmost point does not tolerate that continuing waste goes down, improve and ban this common equipment and traditional method, too impatient to wait.
Summary of the invention
The object of the invention is to be to overcome the deficiency of prior art, provide a with low cost, economical, draw materials easily, simple operation, safe and reliable, the especially this FAR INFRARED HEATING stove that prevents a motor winding of inflammable and explosive substances breaking out of fire.
The present invention is in order to solve its technical problem, and the technical scheme of taking is:
1. FAR INFRARED HEATING principle: FAR INFRARED HEATING object is a new technology, while having economize on electricity, saving of labor, joint, quality is good, easily build many superiority of easily repairing.Infrared ray is a kind of electromagnetic wave between visible ray and microwave, and its wavelength is between 0.72 to 1000 dimension rice.Infrared ray is divided each wave bands such as near infrared ray, middle infrared (Mid-IR), far infrared again, and distinguishing limit is also not exclusively unified, somely above claims far infrareds 30 microns, but also 5.6 microns of handlebars above be called far infrared.Propagation and the visible ray of far infrared are similar, and circuitous when the object when light, a part is reflected by the object, and once minute being absorbed by object, another part is propagated forward through object.When the molecular motion aggravation of material, object temperature rising radiant energy directly becomes heat energy, thereby reaches the effect of heat drying.Radiation is that heat energy is propagated with electromagnetic form, do not need intermediary, thereby the little speed of heat loss is fast.
