The "closed tank" of concrete mixer refers to that the impeller of concrete mixer is suddenly blocked by concrete and can not roll. In this case, the main motor of the mixer will stop running when it is charged. If the electrical maintenance part is not maintained in time, or the maintenance time and other parameters are set unreasonably, the main motor may be burned. The following small series to introduce the reasons for the concrete mixing tank stewing tank and how to prevent the concrete mixing tank from sticking to the tank.

　　一、混凝土攪拌機(jī)“悶罐”的原因

　　1、 Causes of concrete mixer's "stuffy tank"1、主電機(jī)皮帶過(guò)松，動(dòng)力傳遞缺乏。這種情況下，攪拌機(jī)內(nèi)攪拌阻力稍大，就可能被卡住，從而形成悶罐現(xiàn)象。

　　1. The belt of main motor is too loose and the power transmission is lack. In this case, if the mixing resistance in the mixer is slightly larger, it may be stuck, thus forming the phenomenon of stuffy tank.

　　2、一次性投料過(guò)多，比方應(yīng)該是兩盤(pán)攪拌量，由于錯(cuò)誤動(dòng)作一次投攪拌機(jī)，那么很就可能悶罐了。有時(shí)候由于攪拌機(jī)開(kāi)門(mén)時(shí)間不合理，上盤(pán)料卸不潔凈也可能形成悶罐。

　　2. One time feeding is too much, for example, it should be two plates of mixing volume. Due to the wrong action, the mixer is likely to be blocked. Sometimes, due to the unreasonable opening time of mixer, the unclean unloading of the upper plate may also form a closed tank.

　　3、攪拌機(jī)內(nèi)襯板磨損嚴(yán)重，或許攪拌葉磨損嚴(yán)重，形成攪拌葉和攪拌機(jī)內(nèi)襯板間隙過(guò)大，或許間隙嚴(yán)重不均勻，也是形成悶罐的多發(fā)原因，這種情況下，攪拌葉與攪拌襯板間必然會(huì)有較多的堅(jiān)固粗骨料，攪拌機(jī)被卡死，也就不足為怪了。

　　3. The inner lining plate of mixer is seriously worn. Perhaps the mixing blade is seriously worn, resulting in the excessive gap between the mixing blade and the inner plate of the mixer, or the gap is seriously uneven, which is also the frequent cause of the formation of the tank. In this case, there must be more solid coarse aggregate between the mixing blade and the mixing lining plate, and it is not surprising that the mixer is stuck.
             

　　4、投料的份額不合理，或許次序不對(duì)，也有可能悶罐，特別是投料中沒(méi)有水，會(huì)大大添加攪拌阻力。

　　4. The feeding proportion is not reasonable, maybe the sequence is wrong, or the tank may be stuffy, especially if there is no water in the feeding, the mixing resistance will be greatly increased.

　　5、攪拌罐車(chē)“抱大軸”（指的是拌和機(jī)主軸粘結(jié)許多混凝土），或許其它部位粘結(jié)過(guò)多的混凝土，也是形成“悶罐”的多發(fā)原因。攪拌機(jī)里邊粘結(jié)東西越多，攪拌阻力越大，嚴(yán)重時(shí)就形成悶罐。這種情況下，操作手應(yīng)密切注意攪拌主機(jī)的電流數(shù)值，電流數(shù)值過(guò)大，就有可能需求整理一下攪拌機(jī)內(nèi)部了；6、攪拌罐車(chē)內(nèi)混入鋼筋棍、鐵板等異物，或者攪拌臂折斷、電機(jī)相間不平衡、電源電壓過(guò)低一級(jí)異常情況也可能形成“悶罐”一般情況下，在一段時(shí)間內(nèi)經(jīng)常性的悶罐，前三種可能性更大一些。假如攪拌電機(jī)電流大，第五種可能性更大。

　　5. Mixing tank truck "holding big shaft" (refers to the mixer spindle bonding a lot of concrete), perhaps other parts of the bond too much concrete, is also the cause of the formation of "closed tank". The more things are bonded inside the mixer, the greater the mixing resistance is, and when it is serious, it will form a closed tank. In this case, the operator should pay close attention to the current value of the mixing machine. If the current value is too large, it may be necessary to sort out the mixer interior; 6. The mixing tank truck is mixed with steel bars, iron plates and other foreign matters, or the mixing arm is broken, the motor phase is unbalanced, and the power supply voltage is too low. Generally speaking, in a certain period of time, the "closed tank" may be formed The first three are more likely to be closed. If the stirring motor current is large, the fifth possibility is greater.
