Paper coil to measure mechanical found by material of aluminum and zinc
First introduced paper making equipment, cutting machine 2400 low-speed cylinder machine production of tea paper board, produced paper width 2600, motor power 30KW, speed 70m/min, starting four years without problems, found the ground coil measurement years after the original press motor bearing damage, the replacement of the new machine after a week again current 60A motor, this change up or full, now, with physical 500W cooling fan, motor temperature is high, treatment measures:
1. reduce pressing line voltage, load estimation can reduce the number of
2. breathable cloth, and the degree of vacuum, pressure, bearing also relations
3. due to soaring metal prices, slitting machine makes motor prices soaring, some owners can not accept the reality, buy motor not expensive, cheap, resulting in some copycat companies play tricks on the coil material motor, some enameled wire is an aluminum wire, also have aluminum coper, different prices, copper components have different. There is a copper alloy and alloy content of different, mainly zinc aluminum material.
