升降貨梯http://www.jntr168.com/常見(jiàn)的故障有制動(dòng)系統(tǒng)液壓站電動(dòng)機(jī)故障、錯(cuò)向運(yùn)行、兩終端過(guò)卷?yè)P(yáng)或超速、主電動(dòng)機(jī)失勵(lì)磁、直流主回路過(guò)電流或過(guò)電壓，以及保護(hù)回路失電等問(wèn)題，一旦發(fā)生該類事故，則必須馬上斷開交、直流回路并進(jìn)行制動(dòng)停車。事故停車故障包括制動(dòng)輪變形、兩終端之間超速、安全門打開、緊急停車后未調(diào)零或調(diào)零電機(jī)故障、操作限位開關(guān)失靈以及尾繩故障等，而信號(hào)預(yù)警類的故障不需停車，而應(yīng)以光、聲等預(yù)警信號(hào)提示作業(yè)人員，該類故障主要包括直流操作電流接地、直流主回路接地、直流主電機(jī)軸承過(guò)熱、制動(dòng)閘瓦磨損以及通風(fēng)故障等。引發(fā)升降貨梯出現(xiàn)故障的因素主要包括操作人員誤操作或違反工藝規(guī)程，現(xiàn)有裝置的保護(hù)功能不夠完善，設(shè)備結(jié)構(gòu)復(fù)雜對(duì)維修人員的技術(shù)經(jīng)驗(yàn)要求過(guò)高，成都升降機(jī)長(zhǎng)時(shí)間、高強(qiáng)度工作而設(shè)備故障的早期預(yù)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.
       
升降貨梯出現(xiàn)故障時(shí)，應(yīng)該及時(shí)對(duì)出現(xiàn)故障的原因進(jìn)行分析，以便及時(shí)為檢修人員排除故障提供科學(xué)的依據(jù)。因此大家應(yīng)該做好升降貨梯事故狀態(tài)的初期預(yù)測(cè)及應(yīng)對(duì)措施，也是決定故障是否能夠有效排除的關(guān)鍵，必須對(duì)升降貨梯http://www.jntr168.com/進(jìn)行全方位的監(jiān)測(cè)，對(duì)各類故障的位置和成因進(jìn)行判別，并采取有針對(duì)性的措施進(jìn)行處理。
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.
