气力输送系统管道被磨损的因素有很多，主要因素如下：

There are many factors for the wear of pneumatic conveying system pipeline, and the main factors are as follows:

1、输送速度

1. Conveying speed

介质速度是影响冲蚀磨损率的主要因素。

The medium velocity is the main factor affecting the erosion wear rate.

2、粒子形状

2. Particle shape

粒子形状对冲蚀磨损的影响主要体现为其对磨损机理的影响。粒子冲击靶材时，粒子与靶材的接触面积决定了两者之间作用强度。尖角形粒子对塑性材料表面的冲蚀多为切削型磨损，球形粒子冲蚀所产生的磨损主要表现为塑性变形磨损。

The influence of particle shape on erosion wear is mainly reflected in its influence on wear mechanism. When the particles impact the target, the contact area between the particles and the target determines the interaction strength between them. The erosion of sharp angular particles on the surface of plastic materials is mostly cutting wear, and the wear caused by spherical particles is mainly plastic deformation wear.

3、粒子强度

3. Particle strength

粒子强度主要是影响粒子在输送过程中的破碎难度与破碎率，以及由此引起的二次磨损。被输送物料的平均粒径随经过弯头数量的增加而呈减小的趋势。这种粒径减小的趋势越明显，相应材料对弯头造成的冲蚀磨损率越高，也就是说，粒子在输送过程中越容易破碎，则其产生的冲蚀磨损率越高。

Particle strength mainly affects the crushing difficulty and crushing rate of particles in the transportation process, as well as the secondary wear caused by it. The average particle size of the conveyed material decreases with the increase of the number of elbows. The more obvious the trend of particle size reduction, the higher the erosion wear rate caused by the corresponding materials on the elbow, that is, the easier the particles are broken in the transportation process, the higher the erosion wear rate.

4、粒子粒度

4. Particle size

粒子粒度对弯头冲蚀磨损的影响与常规冲蚀磨损影响规律类似，即对于不同气力输送条件下的冲蚀磨损，粒径都存在*限值。当粒子粒径大于*限值时，磨损量趋于稳剧。有相关研究表明，冲蚀磨损率随粒子粒度加大而迅速加大。

The influence of particle size on the erosion wear of elbow is similar to that of conventional erosion wear, that is, for the erosion wear under different pneumatic conveying conditions, the particle size has a * limit. When the particle size is greater than the * limit, the wear amount tends to be stable. Relevant studies show that the erosion wear rate increases rapidly with the increase of particle size.

5、物料浓度

5. Material concentration

随着粒子浓度的加大，弯头的总质量损失降低，即单位质量粒子造成的冲蚀磨损量降低，由于悬浮浓度的加大，粒子间撞击的几率也加大，撞击管壁的粒子动能降低。

With the increase of particle concentration, the total mass loss of elbow decreases, that is, the erosion wear caused by unit mass particles decreases. Due to the increase of suspension concentration, the probability of collision between particles increases and the kinetic energy of particles impacting the pipe wall decreases.

6、冲击角

6. Impact angle

冲击角是指入射粒子轨迹与靶材表面之间的夹角。冲击角的不同主要影响了粒子冲击靶材时动能的切向和法向分量，以及在冲击过程中的**消耗。对于冲击粒子来说，动能切向分量是产生切削，而法向分量则是影响粒子压入靶材表面的深*，两者共同决定着磨损量。

Impact angle refers to the angle between the trajectory of incident particles and the surface of the target. Different impact angles mainly affect the tangential and normal components of kinetic energy when particles impact the target, as well as the * * consumption in the impact process. For impact particles, the tangential component of kinetic energy is to produce cutting, while the normal component is to affect the depth * of particles pressed into the target surface, which together determine the amount of wear.

为了减少磨损对生产造成的影响，工业上采取了多种措施来降低气力输送管道的磨损，延长管道的使用寿命，其中降低物料在管道中输送的速度就是一个很好的办法，对于管道外形的优化设计和耐磨材料优选都是比较好的减磨方法。

In order to reduce the impact of wear on production, a variety of measures have been taken in industry to reduce the wear of pneumatic conveying pipeline and prolong the service life of pipeline. Among them, reducing the conveying speed of materials in the pipeline is a good way. It is a better wear reduction method for the optimal design of pipeline shape and the optimization of wear-resistant materials.
