當(dāng)攪拌一體車出現(xiàn)緩慢的送粉現(xiàn)象時，螺旋輸送機(jī)進(jìn)料緩慢，進(jìn)料時間超過2分鐘，在正常進(jìn)料條件下可在20秒內(nèi)送出。
When the mixing truck appears slow powder feeding phenomenon, the screw conveyor feeding is slow, feeding time is more than 2 minutes, under normal feeding conditions, it can be sent out in 20 seconds.
分析了這種失敗的原因：
The reasons for this failure are analyzed
影響因素主要是粉罐的送料不良和螺旋輸送機(jī)的損壞。 粉末進(jìn)料的不良性能的特征在于粉末拱形，粉末罐的排出口處的材料聚集，蝶閥的開口太小以及粉末罐中的材料不足。 螺旋輸送機(jī)的損壞主要是由于螺旋葉片的變形，不能正常運輸。
The main influencing factors are the poor feeding of powder tank and the damage of screw conveyor. The poor performance of powder feed is characterized by powder arch, material accumulation at the discharge port of powder tank, too small opening of butterfly valve and insufficient material in powder tank. The damage of screw conveyor is mainly due to the deformation of screw blade, which can not be transported normally.

方法：
resolvent:
1.打開氣錘破拱裝置。
1. Open the air hammer arch breaking device.
2.檢查粉末罐排放蝶閥的開度，并將蝶閥保持在完全打開位置。
2. Check the opening of discharge butterfly valve of powder tank and keep the butterfly valve in full open position.
3.檢查粉末罐出口處的物料是否結(jié)塊。
3. Check whether the material at the outlet of powder tank is caking.
4.檢查螺旋葉片是否變形。 如果變形，請將其拆下進(jìn)行更正或更換。
4. Check whether the spiral blade is deformed. If it is deformed, remove it for correction or replacement.
如何避免小型攪拌機(jī)中的電擊：
How to avoid electric shock in small mixer:
1.如果小型攪拌機(jī)的供電設(shè)備選擇不當(dāng)或不匹配，將導(dǎo)致觸電和其他生產(chǎn)事故。
1. If the power supply equipment of small mixer is not properly selected or matched, electric shock and other production accidents will be caused.
2，電工是持有證書的操作人員，否則會因用電不足而引起觸電等生產(chǎn)事故。
2. Electrician is a professional operator with certificate, otherwise, electric shock and other production accidents will be caused due to insufficient safety power consumption.
3.如果配電室的操作人員沒有接受過培訓(xùn)，如果攪拌機(jī)缺乏用電和非法操作的知識，導(dǎo)致觸電事故，為什么要避免觸電，引起其他生產(chǎn)事故。
3. If the operator of the distribution room has not received training, if the mixer lacks the knowledge of electricity use and illegal operation, which leads to electric shock, why should electric shock be avoided and other production accidents be caused.
4.配電室運行規(guī)則，操作規(guī)程，警示標(biāo)志，生產(chǎn)記錄，防護(hù)設(shè)施不足可能導(dǎo)致觸電等生產(chǎn)事故。
4. The operation rules, operation regulations, safety warning signs, safety production records and safety protection facilities in the distribution room may lead to electric shock and other production accidents.
5.如果沒有措施防止小動物進(jìn)入配電室，可能會因小動物進(jìn)入而發(fā)生電氣事故，這可能會導(dǎo)致其他事故。
5. If no measures are taken to prevent small animals from entering the distribution room, electrical accidents may occur due to the entry of small animals, which may lead to other accidents.
6.如果配電室的防雷措施不完善，將導(dǎo)致其他生產(chǎn)事故。
6. If the lightning protection measures of the distribution room are not perfect, it will lead to other production accidents.
7，高壓線路下的工作容易發(fā)生電擊。
7. It is easy to get electric shock when working under high voltage line.
8.供電能力和設(shè)施不符合用電要求，影響其正常使用壽命。
8. The power supply capacity and facilities do not meet the requirements for safe use of electricity, affecting its normal service life.
