摘要
为了研究高粉尘浓度下的矿用离心风机关键部件磨损情况,根据气相流体基本方程、颗粒相基本方程以及磨损经验公式,建立离心风机气固两相流磨损模型,采用FLUENT软件对离心风机在高粉尘环境下的工作情况进行仿真,获得并分析了离心风机关键部件的压力分布情况以及表面磨损情况,为改善叶轮的磨损情况、提高离心风机的可靠性和使用寿命提供了理论依据。
In order to study the wearing property of key parts of the centrifugal fan in high dust density operation mode, the wearing model of the centrifugal fan with gas-solid two-phase flow was established according to the basic equations of gas phase, the basic equations of particle phase and the empirical wearing equation. FLUENT was used to simulate the operation of the centrifugal fan in high dust density operation mode, and the pressure distribution and surface wearing state of the key components of the centrifugal fan were obtained and analyzed. The study offered theoretical basis for decreasing abrasion, improving reliability and service life of the centrifugal fan.
