When using the vacuum heat treatment equipment, do not exceed the maximum temperature of the resistance furnace

When using the vacuum heat treatment equipment, do not exceed the maximum temperature of the resistance furnace

 

1. Do not exceed the maximum temperature of the resistance furnace during use.

 

2. Be sure to cut off the power supply when loading the sample to prevent electric shock.

 

3. When loading and taking samples, the opening time of the furnace door should be as short as possible to prolong the service life of the electric furnace.

 

4. It is forbidden to pour any liquid into the furnace.

 

5. The samples stained with water and oil shall not be put into the furnace; the samples shall not be loaded with clips stained with water and oil.

 

6. Wear gloves when loading and taking samples in the box-type resistance furnace to prevent burns.

 

7. The sample should be placed in the middle of the furnace, neatly placed, and should not be placed randomly.

 

8. Do not touch the electric furnace and the surrounding samples casually.

 

9. After use, the power supply and water source should be cut off.

Vacuum drying equipment improves electrical strength

The breakdown strength of air is much lower than that of various insulating materials of the motor, and because the relative dielectric coefficient of the air gap is small, the electric field strength is the highest. In addition, after the insulating paint fills the insulating gaps and capillaries, it can improve the distribution of the electric field, and also play the role of repairing the weak points of the insulation, thus improving the insulation electric strength of the motor.

Vacuum drying equipment improves winding resistance to external environment

Motors are usually run in an environment with humidity, alkali, salt and other harmful gases, resulting in accelerated deterioration of insulation performance and even insulation breakdown. After the motor winding is impregnated by a vacuum varnishing machine, the erosion rate of the external environment can be slowed down.
