升降货梯常见故障如何应对？

升降货梯http://www.jntr168.com/常见的故障有制动系统液压站电动机故障、错向运行、两终端过卷扬或超速、主电动机失励磁、直流主回路过电流或过电压，以及保护回路失电等问题，一旦发生该类事故，则必须马上断开交、直流回路并进行制动停车。事故停车故障包括制动轮变形、两终端之间超速、安全门打开、紧急停车后未调零或调零电机故障、操作限位开关失灵以及尾绳故障等，而信号预警类的故障不需停车，而应以光、声等预警信号提示作业人员，该类故障主要包括直流操作电流接地、直流主回路接地、直流主电机轴承过热、制动闸瓦磨损以及通风故障等。引发升降货梯出现故障的因素主要包括操作人员误操作或违反工艺规程，现有装置的保护功能不够完善，设备结构复杂对维修人员的技术经验要求过高，成都升降机长时间、高强度工作而设备故障的早期预兆未被注意等。

Common faults cargo lifter hydraulic brake system of the motor failure, wrong to run over two terminal winch or speeding, lost the main motor excitation, DC main circuit overcurrent or overvoltage protection circuit as well as issues such as loss of power, in the event kind of accident, you must immediately disconnect the AC and DC circuits and parking brake. Parking fault accident, including brake wheel deformation between the two terminal speed, security door open, not adjusted after an emergency stop zero or zero motor failure, operation of the limit switch failure and tail rope failure, and the signal failure without warning like parking , but should be light, sound and other warning signals prompted workers, such failure include DC operating current grounding, DC main circuit grounding, DC main motor bearings overheating, brake pad wear and ventilation failure. Factors that lead to failure of the main cargo lifter include operator misuse or breach of technical rules, protection of existing installations is not perfect, the device structure of complex technical experience requirements for maintenance staff too, Chengdu lift a long, high-intensity work and equipment early harbinger of failure and so unnoticed.
       
升降货梯出现故障时，应该及时对出现故障的原因进行分析，以便及时为检修人员排除故障提供科学的依据。因此大家应该做好升降货梯事故状态的初期预测及应对措施，也是决定故障是否能够有效排除的关键，必须对升降货梯http://www.jntr168.com/进行全方位的监测，对各类故障的位置和成因进行判别，并采取有针对性的措施进行处理。
When cargo lifter fails, should be timely to analyze the reasons for failure to timely maintenance personnel to troubleshoot and provide scientific basis. Therefore, we should do the initial state Huoti accident prediction and response measures, but also the key to whether the failure to effectively decide to exclude, you must carry out a full range of cargo lifter monitoring, fault location and causes all kinds of discriminate and adopt targeted measures to deal with.
