【摘要】：总结分析了多风机联合作业存在的问题,多风机联合作业相互影响分析的理论依据。结合实例,通过理论分析、仿真模拟、现场实测的方法研究多风机联合作业的有效性及失效预防方法。实例分析发现,4台风机(大风量)联合作业时,可调性更强,但稳定性较难控制;两台风机(大风压)并联作业时,稳定性方面较好,但可调性较差。两种情况下,在一定范围内,风机效率相差不大,均能达到80%以上。此外,4台风机两两先并后串,风机启动时,随着运转风机数量的增加,风量逐渐增加,这一过程并不遵守"并联风量相加"的原则,但当4台风机均启动并达到稳定运行时,风机与风网及风机之间是相匹配的。最后,从风机配置及风网调节两个方面提出了相关的失效预防措施。
[Abstract]:This paper summarizes and analyzes the problems existing in the joint operation of the multi fan and the theoretical basis of the mutual influence analysis of the joint operation of the multi fan. The effectiveness and the failure prevention method of the joint operation of the fan are studied through the theoretical analysis, simulation and field measurement with a practical example. The case analysis finds that the 4 typhoon machine (large air volume) combined operation is adjustable. Stronger, but the stability is difficult to control; two the typhoon machine (large wind pressure) parallel operation, the stability is better, but the adjustability is poor. Under two cases, in a certain range, the fan efficiency is not very different, can reach more than 80%. In addition, 4 typhoon machine 22 first and rear string, when the fan starts, with the increase in the number of operating fans, the air volume gradually increases. This process does not comply with the principle of "parallel wind volume addition", but when the 4 typhoons are all started and reached stable operation, the fan and the wind network and the fan are matched. Finally, the related failure prevention measures are put forward from two aspects of the fan configuration and the wind network adjustment.
