  搅拌一体车多数时间的施工条件比较恶劣,在生产过程中也会经常出现一些缺点,如不能及时处理,将严重影响工程项目的施工进度与质量。下面我们就来说说搅拌一体车运行出现抱轴现象的原因是什么。
  Mixing vehicle most of the time the construction conditions are relatively bad, in the production process will often appear some shortcomings, such as timely treatment, will seriously affect the construction progress and quality of the project. Here we say what is the reason for the phenomenon of holding the axle in the operation of the mixing vehicle.
  搅拌一体车的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。
  The design of feeding device of mixing vehicle is unreasonable. Such as cement and fly ash feed port location and direction is not reasonable, resulting in a large part of the powder into the shaft, so that bonding on the shaft to form a “holding shaft” phenomenon. Flush point position and flush direction is incorrect, or flush pressure is too low.
  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
  When washing the tank, the concrete stuck on the mixing device can not be washed off, forming the phenomenon of “holding the shaft”. The volume utilization ratio of the mixing cylinder is unreasonable, and the volume utilization ratio is too small to expose the mixing shaft to the concrete, and the part of concrete adhered to above will not be stirred and solidified on the shaft to form the phenomenon of “holding the shaft”
  为了使混凝土不发生离析现象,搅拌叶片线速度应受限于搅拌臂外端的大值。这样,在靠近搅拌轴的一端,由于线速度相对较低,就形成了搅拌低效区甚至死区。
  In order to avoid concrete segregation, the linear velocity of the mixing blade should be limited to the maximum value of the outer end of the mixing arm. In this way, at one end close to the mixing shaft, low efficiency zone or even dead zone is formed due to relatively low linear velocity.
  同时,随着搅拌机容量的增大,其搅拌筒半径尺寸就要比搅拌叶片的高度大得多,因此当搅拌轴转动时,叶片只能搅动靠近拌筒内壁的一层物料,料层高即为叶片的高度,而处于搅拌叶片和搅拌轴之间的很大一段距离的物料将无法得到很好的搅拌。
  At the same time, with the increase of capacity of mixer, the mixing cylinder radius size is much larger than the height of the mixing blade, so when the stirring shaft rotational blade can only stir up close to add a layer of material for the inner surface of cylinder, the height is the height of the blade, and stir in a big distance between the blade and the stirring shaft materials will not be able to get good agitation.
  显然,此时搅拌低效区问题就更严重。低效区内混合料运动缓慢,各相间的对流、渗透作用不剧烈,容易使混合料粘附在搅拌轴上,形成“抱轴”现象。
  Obviously, at this time, the problem of low efficiency mixing zone is more serious. In the low-efficiency area, the mixture moves slowly, and the convection and infiltration of each phase are not intense, which makes the mixture adhere to the mixing shaft easily and form the phenomenon of “holding the shaft”.
  当大家在使用搅拌一体车的过程之中如果遇到了抱轴现象的话一定要及时的将具体的原因找出来,这样才可以快速进行解决,以免影响到大家的正常工作。更多问题的了解您可以通过网站www.jfhntjbc.com来联系我们进行咨询。
