随着社会城市化进程不断向前推进,混凝土需求量不断增加,所以对自动搅拌车的搅拌主机的性能提出更为严格的要求。同时要求降低故障率,减少生产过程中出现的问题,自动搅拌车的搅拌主机“抱轴”则是生产过程中常见的问题之一。
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.
自动搅拌车"抱轴"是什么意思?引起这种现象的原因是什么
What is the meaning of "axle holding" of automatic mixer? What is the cause of this phenomenon
自动搅拌车的搅拌主机抱轴是指在搅拌过程中粉料、砂石和液体混合所形成的粘结物,黏附在搅拌轴和搅拌臂上,在其表面形成一层非常厚且不易清理的粘结物。目前混凝土搅拌站使用蕞多的是双卧轴强制搅拌主机,其效率高,搅拌效果好。但一旦抱轴就会产生很多危害,搅拌主机抱轴后会影响混凝土质量,使打出的混凝土搅拌不均匀。
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.
自动搅拌车出现抱轴现象,如果不及时停机清理,抱轴的混凝土会越来越多,增加搅拌机的负载,使其耗能增加,当超过一定负载时搅拌主机电机会因过载形成堵转,造成电机烧毁。影响耐磨件以及轴端密封寿命,加速耐磨件的磨损,抱轴后搅拌臂的磨损十分严重,使其寿命大大降低。
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.
下面咱们再来一起分析一下自动搅拌车的搅拌主机“抱轴”的原因:
Next, let's analyze the reason why the mixing machine of the automatic mixer truck "holds the shaft":
首先可能是因为投料装置设计的不合理。如水泥和粉煤灰进料口位置及方向不合理,导致粉料很大一部分投放到轴上,以致粘结在轴上形成“抱轴”现象;冲水点的位置和冲洗方向不正确,或者冲水压力过低。在冲洗罐内时,搅拌装置上粘着的混凝土冲洗不掉,形成“抱轴”现象;搅拌筒的容积利用率的大小不合理,容积利用率太小将使搅拌轴暴露在混凝土上面,粘附在上面的一部分混凝土将得不到搅拌而凝固在轴上形成“抱轴” 现象;搅拌臂在靠近搅拌轴的一端线速度太低。
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.
