摘要
为了减少能量损耗且同时满足紧密纺和落棉系统的除尘要求,将单节48锭紧密纺风系统和小型化落棉风系统组合设计为一个风系统.通过试验对组合系统进行验证,并采用三维建模软件PROE与CFD软件FLUENT对系统进行三维数值模拟,分析了组合系统内部流场的风速、压力和流量的变化情况.结果表明:紧密纺系统测点平均风速为9 m/s,达到了紧密纺系统孔口风速要求;落棉系统测点平均风速为7.8 m/s,与落棉系统孔口风速要求相差了0.2 m/s,误差仅为2.5%,在误差允许范围内,说明该组合系统设计合理;风道内部风速和压力分布相对稳定,说明该组合系统稳定性较强,符合流体力学节点压力相等的设计理论.
In order to reduce energy loss and meet their own cleaning requirements of the compact spinning and noil system,the single section 48 spindle compact spinning wind system and miniature noil wind system are combined to design as a wind system. The combinatorial system is verified by the test and simulated by using 3 D modeling software PROE and CFD software FLUENT, the changes of internal flow field of velocity, pressure and flow for the combinatorial system are analyzed. The results show that the average wind speed at the test points of the compact spinning system is 9 m/s, which meets the orifice wind speed requirements of the compact spinning system. The average wind speed at the test points of the noil system is 7.8 m/s, which has a difference of 0.2 m/s from the orifice wind speed requirements of the noil system, the error is only 2.5%,within the error range, it shows that the design of the combinatorial system is reasonable. The distribution of wind velocity and pressure in the interior of wind duct is relatively stable, which indicates that the combinatorial system has strong working stability and accords with the design theory of equal pressure of node in fluid mechanics.
