1、 设备磨损严重，速率太快：

1. The equipment is worn seriously and the speed is too fast

新设备各部分零件由于表面粗糙度的问题会存在配合不完全、表面承载应力不均匀等情况。在这样的工作状态下，零件表面由于互相嵌合而摩擦，进而产生磨损的金属碎屑作为二次磨料参与摩擦过程，这势必会导致零件表面的磨损加剧。因此，磨合期内磨损严重、速率快。若是在这段时期内处于生产旺季而超负荷工作，零件的破损度则会更为严重，缩短设备的使用寿命。

Due to the surface roughness of parts of new equipment, there are some problems, such as incomplete fit, uneven surface bearing stress and so on. In such a working state, the surface of the parts will rub due to mutual chimerism, and then the worn metal debris will participate in the friction process as the secondary abrasive, which will inevitably lead to the aggravation of the wear of the surface of the parts. Therefore, the wear in period is serious and fast. If in this period of time in the production season and overload work, parts damage will be more serious, shorten the service life of the equipment.

2、 润滑不充分：

2. Insufficient lubrication:

配合零件的紧密度差是导致润滑效果不好的关键原因，润滑油在摩擦表面覆盖度及形成油膜程度差使得精 密配合的摩擦表面相互划伤。

The poor tightness of mating parts is the key reason for poor lubrication effect. The poor coverage of lubricating oil on the friction surface and the poor degree of oil film formation make the friction surfaces of precision mating scratch each other.
           

3、 零部件之间松动：

3. Loose between parts:

新的商品混凝土搅拌装置的各个零件之间普遍存在着几何外形和尺寸配合的差异，当周围环境温度变化时，热胀冷缩效应会不同程度的造成零件尺寸产生相互配合差异。这就导致了本来紧固的各部分产生松动、配合度差的问题。

When the ambient temperature changes, the effect of thermal expansion and cold contraction will cause the size difference of parts. This leads to the problems of looseness and poor fit of the original fastening parts.

4、 技术人员操作失误：

4. Operator error:

接触新设备的操作人员对机器构造和使用注意事项的不熟悉，往往是造成失误操作的主要原因。这在一定程度上可以经过的技术培训而得到避免。

The operators who contact with new equipment are not familiar with the machine structure and precautions, which is often the main cause of misoperation. This can be avoided through professional technical training to a certain extent.
