Explosion proof motor is a kind of motor that can be used in flammable and explosive places. It does not produce electric sparks when running. Explosion proof motor is mainly used in coal mine, petroleum, natural gas, petrochemical industry and chemical industry. In addition, it has been widely used in the fields of textile, metallurgy, city gas, transportation, grain and oil processing, paper making, medicine and so on. As the main power equipment, explosion-proof motor is usually used to drive pumps, fans, compressors and other transmission machinery.
(1) the corresponding relation of power level, installation size and speed is consistent with DIN42673. At the same time, it is necessary to adjust the YB series inheritance and Y2 series interchangeability to make it more effective and applicable.
(2) the whole series adopts F class insulation, and the temperature rise is B grade.
(3) the noise limit is lower than that of the YB series, which is close to that of the YB series I noise, and the vibration limit is quite the same as that of the YB series.
(4) the shell protection level is increased to IP55.
(5) the whole series adopts low noise deep groove ball bearings, the center height of the machine is over 180mm, and the motor is provided with oil injection and discharge devices.
(6) the motor radiator has two parallel horizontal distribution and radiation distribution, mainly parallel horizontal distribution.
