中科聚峰搅拌车后面的大筒为什么边走边转?

  虽然经常可以看到混凝土搅拌罐车的罐体在行驶过程中总是会转弯,但是很多人对此有不同的看法,很多人认为原因很简单。刚出搅拌站的混凝土是初始材料,刚出搅拌站后进行简单的配料搅拌,为了保证混凝土的均匀性,需要在混凝土搅拌车上进行二次搅拌。
  Although it is often seen that the tank body of the concrete mixer truck always turns when driving, many people have different views on this, and many people think that the reason is very simple. The concrete just out of the mixing plant is the initial material. After just out of the mixing plant, simple batching and mixing are carried out. In order to ensure the uniformity of concrete, secondary mixing is required on the concrete mixer.
  一般混合槽汽车需要保证10到30转速度,夏天可能会更低,只需要保护混凝土隔离不发生和初始设置,过于频繁的激动人心的可能会导致过多的水蒸发混凝土卸料的和易性差,影响混凝土质量的组件放置,体现在蜂窝麻面漏钢筋等质量缺陷。
  Generally, the mixing tank car needs to guarantee the speed of 10-30 revolutions, which may be lower in summer. It only needs to protect the concrete isolation from occurrence and initial setting. Too frequent and exciting may lead to too much water evaporation and poor workability of concrete unloading, affecting the placement of components of concrete quality, which is reflected in quality defects such as honeycomb, pitted surface and steel leakage.

  混凝土搅拌罐车运输过程中的二次搅拌属于深加工,但不是简单的旋转。太慢,混凝土中的粗骨料容易下沉,太快,对驾驶员的安全有一定的影响,而且还会增加混凝土的失水,坍落度增大,影响流量;当转速为6~8 /min时,混凝土初凝时间一般为3~6小时。短暂的交通堵塞对混凝土的影响很小。如果交通堵塞时间过长,混凝土罐的旋转次数应适当加快1~2个周期,并注意罐的旋转是否异常。适当时可加水,以保持混凝土的和易性,避免混凝土粘滞。
  The secondary mixing in the transportation process of concrete mixer truck belongs to deep processing, but not simple rotation. Too slow, the coarse aggregate in the concrete is easy to sink, too fast, which has a certain impact on the safety of the driver, but also increases the water loss of the concrete, the slump increases, and affects the flow; when the rotation speed is 6-8 / min, the initial setting time of the concrete is generally 3-6 hours. Short traffic jams have little effect on the concrete. If the traffic jam time is too long, the rotation times of the concrete tank shall be appropriately accelerated for 1-2 cycles, and attention shall be paid to whether the rotation of the tank is abnormal. When appropriate, water can be added to maintain the workability of concrete and avoid concrete adhesion.
  缩短了混凝土的初凝时间,改善了混凝土的物理性能。
  It shortens the initial setting time of concrete and improves the physical properties of concrete.
