Storage period of more than six months or shut down more than 2 months after the use of explosion-proof motor, you should check the condition of the bearing device. If there is serious pollution, oil, oil dry, parts, corrosion and other conditions, explosion-proof motor bearing device disintegrated, thoroughly clean the bearings and bearing parts (filling pipe, bearing cover, bearing cover, block oil ring, oil drain boxes, etc.), and then re-lubrication. Rolling internal should be filled grease filling amount of grease filling a cavity formed with the bearing outer cover for the bearing cover 1/3-1/2 of the entire cavity.

    Grease after a period of time of use, the characteristics will deteriorate, will reduce the lubrication function, so to replenish the grease. Grease replenishing interval and the number of supplementary playing in the explosion-proof motor oiling board should be in accordance with the oiling card data replenish grease, in order to ensure reliable operation of the rolling bearing.

    Oiling board refueling cycle and the number of 70 ° C and working condition for bearing, bearing temperature exceeds 70 ° C, the bearing temperature increased every 15 ℃, grease supplement interval is reduced by half.

    Regular maintenance of the equipment, to the reliable operation of explosion-proof motor within the next maintenance cycle should be dismantling the bearing device, if necessary, replace bearings.
