Industrial Electric Motor Drying Oven, Curing Oven for Motor Coil
Baking
1.Working Principle
The motor drying oven is a special motor drying equipment with hot
air circulation
and automatic intelligent control of the whole process. The top of
the motor curing
oven is equipped with a large air volume, low noise and temperature
resistant centrifugal
fan, The heating chamber is set in the air ducts on both sides of
the inner liner.
When working, the air is supplied vertically from the lower part of
the left and right
air ducts (about 1 / 3 height) in the working chamber, so that the
parts are heated
from all directions. After full heat exchange between the hot air
in the working
chamber and the workpieces, the hot air evenly flows back to the
top suction
chamber, and then is sent to the air ducts on both sides (heating
chamber)
through the fan for heating again. This cycle repeats all the time.
The forced
hot air circulation is carried out by the circulation fan with
large air volume
and high air pressure so as to ensure the good temperature
uniformity in the
working chamber. The temperature in the vacuum impregnation process
can meet the process requirements.
This motor baking oven has the characteristics of high temperature
control precision,
simple operation, energy saving, high safety and reliability.Vacuum
pressure impregnation
plant is widely used in coil impregnation drying (curing) process
of motor
industry and curing after epoxy dry casting.

3.Structure
| Oven Body |
| Structure type | Integral type |
| Door opening method | Right-left door. |
| Shell | Q235 cold rolled steel plate with surface phosphating treatment,
and acrylic sefl-drying paint is used. |
| Inner layer | It is made of Q235 cold rolled steel plate. Before welding, the
steel surface is sprayed with w61 series silicone heat-resistant
paint (400 ℃). |
| Shell framework | It is made of Q235 channel steel and angle steel. Before welding,
the steel surface is treated with rust removal and rust prevention. |
| Inner layer framework | It is made of Q235 steel. Before welding, the steel surface is
derusted and degreased, and then sprayed with w61 series silicone
heat-resistant paint (400 ℃). |
| Base tray | It is made of Q235 channel steel. After rust removal and antirust
treatment, 851 moisture-proof paintis sprayed on the surface
|
| Heat preservation material | Adopt the quality silicate aluminum cotton. |
| Sealing material | Asbestos rope and silicone rubber plate are used for sealing the
door and oven body, and asbestos belt is used for sealing the fan. |
| Electrical System |
| control cabinet | Independent cabinet |
| Power supply | 3N+PE 380V 50Hz |
| Alarm | Domestic digital temperature control alarm, temperature sensor
PT100 |
| Protection system | One set of over temperature alarm system. When the temperature in
the oven is abnormal, it will send out sound and light alarm, and
automatically cut off the heating power. b) Motor overloading protection to prevent motor burning and
tripping. c)Protect electric heater from short circuit. Schneider brand. d) The heating components are controlled by solid state relay.
Miguel electric. e)The motor and heating interlock device. The blower should be
started first, and after that the heater can be turned on. f) Control circuit protection to prevent circuit short circuit and
accident. g) Air switch to prevent the main circuit overloading and short
circuit, causing accidents. |
Notes: Unmentioned points should be according GB5170-85 and
JB/T5520-91 standard.
