Motor damp treatment method

Wet is a fatal factor leading to motor failure, can invade the motor from splashing rain or by condensation of moisture, especially during the intermittent operation when the motor is in the park a few months later, check before coil insulation, otherwiseit is easy to burn out the motor.

If the motor is damp can be used in several ways:
 
1 Circulating hot air drying method: Thermal insulation materials made of a drying chamber (such as brick masonry), above left vent, side air inlet. Air inlet connected to the heating chamber to pass, heated indoor set about 3kW 220V electric wire insulation (heating chamber also other methods can be used to heat). Heating chamber can be the tin made, heated indoor hot air blown into the drying chamber to the motor windings drying with a hair dryer. The hot air temperature control of the drying chamber at 100 ℃.

2 bulb drying method: one or number only high-power incandescent bulbs (100W) into the motor cavity drying. Note: The bulb is not too close to the coil to prevent burn out the coil. Insulation covered with canvas and other objects on the motor housing.

3, there is also available desiccant: (1) Quicklime desiccant. The main component is calcium oxide, and its water absorption capacity is achieved by chemical reaction, and therefore the water-absorbent having irreversibility. Regardless of the level of humidity of the external environment, it can be kept more than the weight 35% of the absorbent capacity, more suitable for use in low temperature preservation, having excellent drying hygroscopic effect, and lower prices. (2) silica gel desiccant. This water vapor permeability of different varieties of pouch packaging silica gel desiccant is the main raw material for silicone is a high water content of the porous structure silica, non-toxic, tasteless, odorless, chemically stable, with a strong moisture absorption. Relatively more expensive.
