1、河北升降货梯http://www.rgsjpt.com/电机故障，电机内部都是由铁芯和绕组线圈组成的，绕组有电阻，通电会产生损耗，损耗大小与电阻和电流的平方成正比，这就是我们常说的铜损。如果电流不是标准的直流或正弦波，还会产生谐波损耗；铁心有磁滞涡流效应，在交变磁场中也会产生损耗，其大小与材料，电流，频率，电压有关，这叫铁损。铜损和铁损都会以发热的形式表现出来，从而影响电机的效率。电机一般追求定位精度和力矩输出，效率比较低，电流一般比较大，且谐波成分高，电流交变的频率也随转速而变化，因而河北升降货梯电机普遍存在发热情况，且情况比一般交流电机严重，此时应当及时联系生产厂家或专业维修人员，进行检修。
Shandong cargo lifter motor failure, internal motor core and windings are made consisting of windings resistance, power will produce losses, the loss is proportional to the square of the size and resistance and current, and this is what we often say that the copper loss. If the current is not a standard DC or sine wave, but also produce harmonic losses; vortex core has a hysteresis effect in an alternating magnetic field will produce loss, its size and materials,current, frequency, voltage, called iron loss . Copper and iron losses will be manifested in the form of heat, thus affecting the efficiency of the motor. Motors are generally pursue positioning accuracy and torque output, efficiency is relatively low, the current general relatively large, and high harmonic components, the frequency of the alternating current with the speed of change, and therefore the prevalence of fever Shandong cargo lifter motor case and the situation than the average exchange motor serious, this time should contact the manufacturer or qualified service personnel for maintenance.

2、河北升降货梯油管堵塞，检查油管是否流通顺畅，液压油流通不畅会给液压系统带来负担，使泵站发热。
Shandong cargo lifter tubing plug, check whether the smooth flow tubing, hydraulic oil flow of the hydraulic system will burden the poor, so that the heat pump station.

3、河北升降货梯http://www.rgsjpt.com/设备超载，检查货物是否超过额定载荷，造成泵站过热，超载会严重影响使用寿命。
Shandong overloaded cargo lifter device to check whether the goods exceeds the rated load, resulting in overheating of the pump station, overloading will seriously affect the life.
