大型混凝土攪拌機的故障有很多種,比如發(fā)動(dòng)機故障、液壓系統故障、電路故障、操作閥故障等等,大型混凝土攪拌機給大家介紹一下出現故障需要維修的時(shí)候,需要注意哪些問(wèn)題?要做的就是斷電,在斷電之前要將點(diǎn)火開(kāi)關(guān)關(guān)閉,同時(shí)還要關(guān)閉用電設備,比如音響等設備,禁止電器設備運行時(shí)突然斷電。具體斷電順序如下:為先,所以在維修的時(shí)候要拔掉負極,再拔正極,安裝的時(shí)候順序是相反的,先裝正極,后裝負極。
There are many kinds of failures of large-scale concrete mixer, such as engine failure, hydraulic system fault, circuit fault, operation valve fault, etc. for large-scale concrete mixer, what problems need to be paid attention to when there is a fault and need to be repaired? The first thing to do is to cut off the power. Before the power is cut off, the ignition switch should be turned off. At the same time, the electrical equipment, such as audio equipment, should be turned off. The specific power-off sequence is as follows: safety first, so the negative pole should be pulled out first and then the positive pole should be pulled out during maintenance. The order of installation is the reverse, and the positive pole should be installed first and then the negative pole.
為什么先斷負極呢?大型自動(dòng)混凝土攪拌機在這里給大家解釋一下:
Why cut off the negative pole first? Large automatic concrete mixer here to explain:
1. 先拆正極存在燒壞電器元件的風(fēng)險,容易引起電腦板燒毀的損失。在電路的實(shí)際維修過(guò)程中因違反操作規程,損壞電路和把手燒傷的人很多,因為蓄電池正負極短路電流非常大,能瞬間產(chǎn)生高溫。
1. Remove the positive electrode first, there is a risk of burning out the electrical components, which is easy to cause the loss of computer board. In the actual maintenance process of the circuit, there are many people who damage the circuit and burn the handle because of violating the operation rules. Because the short-circuit current of the positive and negative electrodes of the battery is very large, it can produce high temperature instantly.
2. 如果先拔掉正極,因負極是搭鐵的,也就是正極周?chē)慕饘佘?chē)體都是負極,如果用工具拆卸正極接線(xiàn)時(shí),工具碰到旁邊的金屬車(chē)體,就會(huì )造成蓄電池正負極短路。
2. If the positive pole is pulled out first, because the negative pole is grounded, that is, the metal car body around the positive pole is all negative pole. If the tool touches the metal car body nearby when removing the positive connection with a tool, it will cause a short circuit between the positive and negative poles of the battery.
3. 如果先拔掉負極,因負極周?chē)慕饘佘?chē)體與負極是連通的,即使工具碰到也不會(huì )產(chǎn)生什么壞的結果,當負極拔掉后已經(jīng)斷電,再去拔正極就不會(huì )有什么危險了。
3. If the negative pole is pulled out first, because the metal car body around the negative pole is connected with the negative pole, even if the tool touches it, it will not produce any bad results. When the negative pole is pulled out and the power has been cut off, it will not be dangerous to pull the positive pole again.
大型混凝土攪拌機要注意一點(diǎn):現行的攪拌車(chē)的蓄電池都是有總開(kāi)關(guān)的,但是原來(lái)的都沒(méi)有,就不好操作;而且如果是危險品運輸車(chē),比如油罐車(chē),車(chē)上的行車(chē)記錄儀是不允許斷電的,斷電后行車(chē)記錄儀不能工作,車(chē)主可能就要承擔法律責任了,但是如果是危險品運輸車(chē),可以在車(chē)上放置一個(gè)供行車(chē)記錄儀的備用電源,這樣即使電路出現故障,也不于讓行車(chē)記錄儀斷電。
One thing to pay attention to for large-scale concrete mixer: the battery of the current mixer truck is equipped with a master switch, but the original one is not available, so it is not easy to operate; moreover, if it is a dangerous goods transport vehicle, such as an oil tank truck, the vehicle's tachograph is not allowed to be powered off. After the power failure, the vehicle's recorder can not work, the owner may have to bear legal responsibility, but if it is dangerous goods A backup power supply for the tachograph can be placed on the transport vehicle, so that even if the circuit fails, the tachograph will not be cut off.
