Explosion proofMotorInsulation treatment is very critical. Not only can we protect the information security of the explosion-proof motor in operation, but also guarantee it.Explosion-proof motorsThe service life of the explosion-proof motor enables students to effectively ensure the normal production and operation of the company in the management of some humid and corrosive environmental problems.Explosion-proof motor is a kind of motor that can be used in flammable and explosive plants and does not generate electric sparks during operation.Explosion-proof motors are mainly used in coal mines, oil and gas, petrochemical and chemical industries.In addition, it is also widely used in sectors such as textiles, metallurgy, city gas, transportation, grain and oil processing, papermaking, and medicine.The motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction.Frequency conversion speed motorA general term for motors driven by frequency converters.In fact, the motor designed for the frequency converter is a special frequency conversion motor. The motor can achieve different speeds and torques under the drive of the frequency converter to adapt to the changes in the demand of the load.Therefore, the insulation treatment of explosion-proof motors is very important!
XNUMX. What are the components of explosion-proof motor insulation?

Explosion-proof motors must form insulating paint after winding between strands, turns, layers, phases, ground and wires.
When the power point is large, a single wire is still used, and when the motor password is high, the number must be added, that is, the multi-strand winding method is selected and the wire cross-sectional area is added to reduce the motor password.For example, the yb series 90kw, 8-pole explosion-proof motor uses 5 pieces of 1.4 enameled wire and windings.
The number of turns is obtained from the intimate scale according to the allowable scale of the magnetic density.In addition to the above five insulations, there are also the insulation of the winding ends and lead wires, and the insulation between the rows when the high-voltage and low-power explosion-proof motor selects the "double-row string" winding.
Second, the significance of insulation technology treatment for explosion-proof motors
(1) The insulation resistance of the motor with improved moisture-proof function
(2) Improve the heat resistance of the company's explosion-proof motor insulation
(3) Improve the thermal conductivity of explosion-proof motors
Improve the electromechanical performance of explosion-proof motor insulation
(5) Improved chemical corrosion functionality
Three, explosion-proof motor insulation technology treatment solutions
It is now happening that stator slot insulation paper or DMD is based on a higher level of motor insulation paper that proves the insulation level requirements, and now "fish paper" has been screened.
After the embedding or binding wiring design is completed, it can be heated and dried by impregnating insulating varnish.The method of dipping paint is different at the same time. General insulating paint, drip dipping insulating paint, vacuum dipping paint, vacuum environment pressure dipping paint, according to the company's explosion-proof motor as the insulation strength level, we choose the corresponding insulating paint and dipping Process technology.The general repair department is to paint and then use an electric stove or light bulb to dry overhead.
