There are many kinds of faults in the self feeding mixer, such as engine fault, hydraulic system fault, circuit fault, operation valve fault and so on. When the mixer needs to be repaired, what problems should be paid attention to? The first thing to do is to cut off the power. Before the power is cut off, turn off the ignition switch. At the same time, turn off the electrical equipment, such as audio equipment. It is forbidden to cut off the power suddenly when the electrical equipment is running. The specific power-off sequence is as follows: safety first, so in the maintenance, first pull out the negative pole, and then pull out the positive pole. The installation sequence is opposite, first install the positive pole, and then install the negative pole.

為什么先斷負(fù)極呢？攪拌機(jī)廠家在這里給大家解釋一下：

Why cut off the negative first? Mixer manufacturers here to explain:

1. 先拆正極存在燒壞電器元件的風(fēng)險(xiǎn)，容易引起電腦板燒毀的損失。在電路的實(shí)際維修過程中因違反操作規(guī)程，損壞電路和把手燒傷的人很多，因?yàn)樾铍姵卣?fù)極短路電流非常大，能瞬間產(chǎn)生高溫。

1. There is a risk of burning out electrical components by removing the positive electrode first, which is easy to cause the loss of computer board burning. In the actual maintenance process of the circuit, there are many people who violate the operation rules, damage the circuit and burn the handle, because the positive and negative short-circuit current of the battery is very large, which can instantly produce high temperature.
              

2. 如果先拔掉正極，因負(fù)極是搭鐵的，也就是正極周圍的金屬車體都是負(fù)極，如果用工具拆卸正極接線時(shí)，工具碰到旁邊的金屬車體，就會(huì)造成蓄電池正負(fù)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 negative pole. If the tool touches the metal car body nearby when removing the positive pole wiring, it will cause a short circuit between the positive and negative poles of the battery.

3. 如果先拔掉負(fù)極，因負(fù)極周圍的金屬車體與負(fù)極是連通的，即使工具碰到也不會(huì)產(chǎn)生什么壞的結(jié)果，當(dāng)負(fù)極拔掉后已經(jīng)斷電，再去拔正極就不會(huì)有什么危險(xiǎn)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, there will be no danger to pull out the positive pole again.

自上料攪拌機(jī)要注意一點(diǎn)：現(xiàn)行的攪拌車的蓄電池都是有總開關(guān)的，但是原來的都沒有，就不好操作；而且如果是危險(xiǎn)品運(yùn)輸車，比如油罐車，車上的行車記錄儀是不允許斷電的，斷電后行車記錄儀不能工作，車主可能就要承擔(dān)法律責(zé)任了，但是如果是危險(xiǎn)品運(yùn)輸車，可以在車上放置一個(gè)供行車記錄儀的備用電源，這樣即使電路出現(xiàn)故障，也不于讓行車記錄儀斷電。

Pay attention to one thing from the charging mixer: the battery of the current mixer has a master switch, but the original one is not, so it is difficult to operate; and if it is a dangerous goods transport vehicle, such as an oil tank truck, the car's dash cam is not allowed to power off, after power off, the dash cam can't work, the owner may have to bear legal responsibility, but if it is a dangerous goods transport vehicle A standby power supply for the dash cam can be placed on the car, so that even if the circuit fails, the power of the dash cam will not be cut off.
