六大方法帮您排除单梁起重机电气故障
Six methods to help you eliminate the electric fault of single beam crane
当单梁起重机电气系统发生故障时,维修人员首先也要用问、看、听、嗅手段对故障进行分析,做到心中有数,“问”就是询问操作司机或现场负责人故障发生时的现象,查询故障前当事人是否对设备做过任何调整或更换元件:“看”就是注意观察每个元件是否正常工作,观看显示器上的各种信号指示是否正确,看电器元件外表颜色是否改变等;“听”就是听电器及线路在工作时有无怪声;“嗅”就是嗅电气线路及元器件有无异味。
When a fault occurs in the electrical system of single beam crane, maintenance personnel should be first to ask, see, hear, smell means of analysis of the fault, be aware of, "ask" is to ask the driver or the person in charge of site operation failure phenomenon, failure of equipment query whether the parties make any adjustment or replacement of components: "look" is to observe each element is working properly, watch all the instructions on the display signal is correct, to see whether to change the color appearance of electrical components; "listen" is to listen to the electrical and wiring has no noise at work; "smell" is sniffing the electric lines and components has no smell.
自动控制的电动单梁起重机,控制线路图虽不太复杂,但电气控制系统故障却比较多,处理电气故障时,要先易后难,先外后内,综合考虑。
The automatic control of electric single beam crane, the control circuit diagram is not too complicated, but the electrical control system fault is more, processing electrical failure, first easy after difficult, first after inside, comprehensive consideration.
1.程序检查法:单梁起重机是按照一定程序运行的,特别是可编程控制器控制的到单梁起重机,它每个环节都有一个独立的控制电路。程序检查法就是要确认故障发生在哪个控制环节,是起升机构还是运行机构上,尽量缩小故障范围,明确排除故障方向,这种方法不仅适用于有触电控制系统。
1. program inspection method: single beam crane is in accordance with certain procedures, especially the programmable controller control to single beam crane, each link has a separate control circuit. Procedure check method is to confirm where the fault occurs in the control link, lifting mechanism or operation mechanism, as far as possible to narrow the scope of failure, clear the direction of the fault, this method is not only applicable to the electric shock control system.
2.电阻测量法:在断电情况下,用万能表的电阻挡测量电子电路的阻止是否正常,或电气线路的通断情况,判断有无故障,因为每个电子元件的正反向阻值不同,任何一个电气元件也都有一定阻值。连接元气件的线路或开关,电阻值不是零就是无穷大,因此测量他们的阻值大小和通断情况就可以判断电子(气)元件的好坏。
2. resistance measurement: in case of power failure, stop measuring circuit with resistance universal table block is normal, or electrical circuit on-off state, determine whether the fault, because reverse the resistance of each electronic component, any electrical components also have a certain resistance value. The circuit or switch that connects the component is not zero or infinite, so it is possible to determine whether the electronic component is good or bad by measuring the magnitude of their resistance and the on-off condition.
3.电位测量法:在通电情况下,测量各电子或电气元器件的两端电位确定故障部位
3. potential measurement method: in the case of power, measuring the electronic or electrical components at both ends of the potential to determine the location of the fault
4.短路连接法:当怀疑某处某个触点或某些触点故障时,可以用导线把某触点后某些触点短接后通电,观察故障现象是否消失。
4. short circuit connection method: when a certain contact or certain contact fault is suspected somewhere, the conductor can be connected with some contacts after the contact to be short, then the power failure is observed.
5.断路法:有时单梁起重机控制线路还可能出现一些特殊故障,查找此类故障的最好方法就是断电法,即将怀疑有故障的触点断开,如果故障消失,就说明判断正确。
5. circuit breaker method: sometimes the single beam crane control circuit may also appear some special faults, the best way to find such failure is the power off method, will be suspected of faulty contacts open, if the fault disappears, that the correct judgment.
6.代替法:当根据以上方法查找出故障出自于某触点或某块电路板时,将有问题的元件或线路板取下,用新的元件或线路板代替,若故障消失,则判断正确;反之则需继续查找。
6. substitution method: when the fault is found out from a contact or a circuit board, the faulty component or circuit board is removed and replaced by a new component or circuit board. If the fault disappears, the correct judgment is made; otherwise, it is necessary to continue to search.
