Explosion-proof  motor is a kind of motor which can be used in flammable and explosive  factory, and does not produce electric spark during operation. Explosion-proof motor is mainly used for coal, oil and gas, petrochemical and chemical industry. In addition, in the textile, metallurgy, city gas, transportation, grain and oil plus,engineering, paper, medicine and other departments are also widely used. Explosion-proof  motors as the main power equipment, usually used to drive pumps, fans,  compressors and other transmission machinery.

       Explosion-proof  motor should be installed before the installation of the explosion-proof  mark on the nameplate and explosion-proof certificate number, motor  voltage and line voltage is consistent. Otherwise, not allowed to install. To check all the bolts are tightened, whether the spring washers are lost, the various parts of the flameproof enclosure whether the pieces are connected. All  the explosion-proof parts shall not have cracks and affect the  performance of the explosion-proof; long-distance transport or long-term  shelving unused explosion-proof motor, must be used before the use of  500V megger to determine the stator winding and chassis insulation  resistance shall not be less than 0.5 trillion Europe, no the motor must be dry until the insulation resistance value is specified. Drying method can be carried out by drying furnace or short circuit current method.  

　  Explosion-proof motor  installation, it should be noted that the center of the motor shaft and  the axis of the machine is rotating the same, otherwise, will cause  damage to the bearing and shaft fracture. Explosion-proof  motor during operation, the shell temperature shall not exceed 110 ℃,  junction box into the line where the temperature shall not exceed 60 ° C. Explosion-proof  motor installation and removal, pay attention to the protection of  explosion-proof surface to be coated with industrial Vaseline or other  anti-rust oil. All the explosion-proof surface  shall not be damaged and rust, otherwise it will lose the  explosion-proof performance of crude oil.

        Our daily use of  explosion-proof motor machine life is relatively long, the problem is  generally some of the removable explosion-proof motor parts, after the  replacement or can be used normally, but also eliminates the need to  replace the expensive motor. Explosion-proof motor is more often replaced accessories  include motor cover, junction box, fan, motor shell, speaker Tsui,  motor bearings and other accessories, the cost of motor replacement is  much more than accessories, but it is worth noting that we need to  replace the accessories must be matching Meet the machine model, as far as possible also is  to find the original manufacturers to replace, some of our customers  have to replace the motor parts when the model is not clear or the  original manufacturers are looking for and can not be replaced. Motor  junction box, fan blades, especially the end caps and chassis must pay  attention to the different manufacturers factory size more or less will be a little out of, so the best way is to contact the original manufacturers to replace.
