长轴井泵在运行中，常发生一些机械故障，机手应当怎样排除呢？1、电动机轴承损坏轴承未加润滑油，或加油量不足产生干磨，油箱漏油或受油环间隙过大，油质不洁有铁屑、水粒等，把电动机轴承磨坏，阻矩增大，引起电动机功率突增，或传动皮带打滑。为避免此类事故，应注意润滑油 Long axis well pump in operation, often some mechanical failure, the driver should be how to exclude it? 1, the motor bearing damage to the bearing without oil, or lack of fuel to produce dry grinding, fuel tank leakage or by the oil ring gap is too large, oil is not clean with iron, water particles, the motor bearing wear and tear, resistance Increase, causing a sudden increase in motor power, or drive belt slippage. To avoid such accidents, attention should be paid to lubricants
