經(jīng)過實(shí)踐和分析，我們認(rèn)為攪拌一體機(jī)粘罐原因可以分為兩大類：即設(shè)計(jì)不合理和使用不當(dāng)，下面我們先從攪拌一體機(jī)卸料殘余率和葉片設(shè)計(jì)不合理方面來講解一番。

Through practice and analysis, we believe that the causes of tank sticking of the mixer can be divided into two categories: unreasonable design and improper use. Let's explain the discharge residual rate and unreasonable blade design of the mixer first.

從攪拌筒的內(nèi)部結(jié)構(gòu)看，攪拌運(yùn)輸車的拌筒是依靠回轉(zhuǎn)的筒體帶動其中的兩條螺旋葉片所產(chǎn)生的螺旋運(yùn)動，使混凝土獲得既有“切向”又有“軸向”的復(fù)合運(yùn)動，從而使攪拌筒具有攪拌和卸料的功能，因此形成這一螺旋運(yùn)動的有關(guān)因素，諸如螺旋葉片的曲線參數(shù)，攪拌筒的幾何形狀和尺寸等對攪拌車的卸料殘余率都有重要影響。

From the perspective of the internal structure of the mixing drum, the mixing drum of the mixing truck is driven by the rotating drum to produce spiral movement by two spiral blades, so that the concrete can obtain a composite movement of both "tangential" and "axial", so that the mixing drum has the functions of mixing and unloading. Therefore, the factors related to the formation of this spiral movement, such as the curve parameters of the spiral blades, The geometric shape and size of the mixing drum have an important influence on the discharge residual rate of the mixer truck.

而過大的卸料殘余率意味著攪拌車在卸料結(jié)束后在攪拌罐里會有更多的余料，因而更有可能因日積月累在攪拌罐中粘料。目前大多數(shù)廠家采用的是等角對數(shù)螺旋線葉片，在卸料殘余率上還有很大的改進(jìn)空間。

However, excessive discharge residual rate means that the mixer truck will have more residual materials in the mixing tank after discharge, which is more likely to stick materials in the mixing tank due to accumulation over time. At present, most manufacturers use equiangular logarithmic spiral blades, and there is still much room for improvement in the discharge residual rate.

此外還有一種情況便是，工地在墻柱等施工中，會用塔吊吊斗車的方法進(jìn)行澆搗，由于塔吊的料本來塌落度就比泵送的低，更由于施工時(shí)間長，卸一車混凝土通常要2～4h，有些駕駛員為了省油而停止攪拌筒的正常轉(zhuǎn)動，這種情況下，特別容易造成粘罐，有時(shí)9方車一次粘罐就達(dá)一整天，這種情況在夏天更嚴(yán)重。

In addition, in the construction of wall and column, the construction site will use the tower crane bucket truck for pouring and tamping. Because the original slump of the tower crane materials is lower than that of the pump, and because the construction time is long, it usually takes 2-4 hours to unload a truck of concrete. Some drivers stop the normal rotation of the mixing drum to save fuel. In this case, it is particularly easy to cause tank sticking. Sometimes, the 9-way truck can stick to the tank for a whole day at a time, This situation is more serious in summer.

夏季在南方地區(qū)白天中午前后，環(huán)境溫度經(jīng)常超過30℃，在這種情況下運(yùn)輸混凝土，將會由于混凝土坍落度損失快以及罐體周圍溫度相對中心更高，因而混凝土更容易粘罐。攪拌一體機(jī)的罐體運(yùn)行是通過液壓的傳動來運(yùn)作的，液壓油長時(shí)間在管路中以一定的速度流動，與管壁摩擦，再加上管路中各種閥件的阻力和油泵的做功，液壓油被壓縮產(chǎn)生熱量，油溫上升。

In summer, around noon in the day in the south, the ambient temperature often exceeds 30 ℃. When transporting concrete in this case, the concrete will be easier to stick to the tank because of the rapid loss of concrete slump and the higher temperature around the tank relative to the center. The tank of the agitator is operated by hydraulic transmission. The hydraulic oil flows in the pipeline at a certain speed for a long time and rubs against the pipe wall. In addition, the resistance of various valves in the pipeline and the work done by the oil pump cause the hydraulic oil to be compressed to generate heat and the oil temperature to rise.

總之混凝土在攪拌車拌筒中的工作是一個非常復(fù)雜的過程，攪拌一體機(jī)粘罐現(xiàn)象的產(chǎn)生原因也是各種各樣的。以上就是為您講解的內(nèi)容了，對此您有什么問題可隨時(shí)來我們網(wǎng)站http://www.cqsgy.com咨詢！
