There are many factors for the wear of pneumatic conveying system pipeline, and the main factors are as follows:
1. Conveying speed
The medium velocity is the main factor affecting the erosion wear rate.
2. Particle shape
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. Particle strength
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. Particle size
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. Material concentration
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. Impact angle
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.
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.
