With the continuous advancement of social urbanization, the demand for concrete is increasing, so the performance of the mixer of automatic mixer is required more strictly. At the same time, it is required to reduce the failure rate and the problems in the production process. The "axle holding" of the mixing machine of the concrete mixer truck is one of the common problems in the production process.

自動(dòng)攪拌車"抱軸"是什么意思?引起這種現(xiàn)象的原因是什么

What is the meaning of "axle holding" of automatic mixer? What is the cause of this phenomenon

自動(dòng)攪拌車的攪拌主機(jī)抱軸是指在攪拌過程中粉料、砂石和液體混合所形成的粘結(jié)物，黏附在攪拌軸和攪拌臂上，在其表面形成一層非常厚且不易清理的粘結(jié)物。目前混凝土攪拌站使用蕞多的是雙臥軸強(qiáng)制攪拌主機(jī)，其效率高，攪拌效果好。但一旦抱軸就會產(chǎn)生很多危害，攪拌主機(jī)抱軸后會影響混凝土質(zhì)量，使打出的混凝土攪拌不均勻。

The shaft holding of the mixer of the automatic mixer truck refers to the binder formed by the mixing of powder, sand and liquid in the mixing process, which adheres to the mixing shaft and mixing arm, forming a very thick and hard to clean adhesive on its surface. At present, the most commonly used concrete mixing plant is the double horizontal shaft forced mixing machine, which has high efficiency and good mixing effect. However, once the shaft is held, there will be a lot of harm, and the quality of the concrete will be affected after the shaft is held by the mixing machine, so that the concrete mixing is uneven.

自動(dòng)攪拌車出現(xiàn)抱軸現(xiàn)象，如果不及時(shí)停機(jī)清理，抱軸的混凝土?xí)絹碓蕉?，增加攪拌機(jī)的負(fù)載，使其耗能增加，當(dāng)超過一定負(fù)載時(shí)攪拌主機(jī)電機(jī)會因過載形成堵轉(zhuǎn)，造成電機(jī)燒毀。影響耐磨件以及軸端密封壽命，加速耐磨件的磨損，抱軸后攪拌臂的磨損十分嚴(yán)重，使其壽命大大降低。

If the machine is not stopped and cleaned in time, there will be more and more concrete holding the shaft, which will increase the load of the mixer and increase its energy consumption. When the load exceeds a certain value, the motor of the mixing machine will be blocked due to overload, resulting in motor burnout. The service life of wear-resistant parts and shaft end seal is affected, and the wear of wear-resistant parts is accelerated. The wear of mixing arm after axle holding is very serious, which greatly reduces its service life.

下面咱們再來一起分析一下自動(dòng)攪拌車的攪拌主機(jī)“抱軸”的原因：

Next, let's analyze the reason why the mixing machine of the automatic mixer truck "holds the shaft":

可能是因?yàn)橥读涎b置設(shè)計(jì)的不合理。如水泥和粉煤灰進(jìn)料口位置及方向不合理，導(dǎo)致粉料很大一部分投放到軸上，以致粘結(jié)在軸上形成“抱軸”現(xiàn)象；沖水點(diǎn)的位置和沖洗方向不正確，或者沖水壓力過低。在沖洗罐內(nèi)時(shí)，攪拌裝置上粘著的混凝土沖洗不掉，形成“抱軸”現(xiàn)象；攪拌筒的容積利用率的大小不合理，容積利用率太小將使攪拌軸暴露在混凝土上面，粘附在上面的一部分混凝土將得不到攪拌而凝固在軸上形成“抱軸” 現(xiàn)象；攪拌臂在靠近攪拌軸的一端線速度太低。

First of all, it may be due to the unreasonable design of feeding device. If the position and direction of the cement and fly ash inlet are unreasonable, a large part of the powder is put on the shaft, resulting in "shaft holding" phenomenon; the position and direction of flushing point are incorrect, or the flushing pressure is too low. When washing the tank, the concrete adhered to the mixing device can not be washed off, resulting in the phenomenon of "shaft holding"; the volume utilization rate of the mixing drum is unreasonable, and if the volume utilization rate is too small, the mixing shaft will be exposed to the concrete, and a part of the concrete adhered to it will not be stirred and will solidify on the shaft to form "shaft holding" The linear velocity of the mixing arm near the mixing shaft is too low.
