Motor housing and stator matching set, how to correctly choose the right heating equipment, not only smooth operation, smooth assembly, but also consider the durability of the equipment, no fault, simple maintenance, followed by the cost of equipment.

First of all, let's take a look at the power frequency electric housing heater, which is also commonly used, relatively economic, durable and not easy to break. Heating method from inside to outside heating expansion, this heating speed, wide range of use, power generally more than ten kilowatts to twenty kilowatts. Below the left picture is blind hole housing heating, right picture is through hole housing heating.

Seen the power frequency heating and then take a look at the high frequency heating, that is, the motor housing high frequency heating equipment, this heating method is made of high frequency induction heating host, output transformer, induction heating ring and water chiller, when the housing is large, need to replace the induction heating ring, the copper ring has been circulating water cooling.

High frequency heater power is large, at least more than 40 kW, the cold water machine to work all the time, you can put the housing in the heating ring heating, can also extend the induction ring inside the housing heating, two kinds of can, the difference is that the housing in the induction ring inside, heating speed.

High frequency has harmonics, it is not recommended to directly handle the case operation, middle and high frequency heating and automation, such as the heating part into automatic lifting, increase pneumatic auxiliary action, the LCD screen display adjustment, PLC Delta or Siemens, the appearance of the atmosphere is more high-end. See the picture below

No matter what kind of heating method is selected, we need to know the shape of the aluminum shell of the motor, whether it is through hole or blind hole, single or double laminated water channel, and the range of inner diameter and length for accurate selection
