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。The problems of multi-ventilator joint operation were summarized,and the interaction theory of this operation was analyzed.Combing with examples,the effectiveness and failure preventive measures of multi-ventilator joint operating were studied by theoretical analysis,numerical simulation and field measurement.The results showed that joint operation with four fans was easier to regulate,but difficult to control the stability;while joint operation with two fans under large wind pressure was on the contrary.In a certain range,the fan efficiency of above two joint modes differed slightly,reaching more than 80%.In addition,the case that two fans in parallel then the other two in series showed that with the increasing number of running fans,the amount of wind gradually increased.But this process didn't comply with the principle of 'parallel air flow together,adding pressure series'.When four fans worked in the stable operation,the fans were matched with air network,and also matched to each other.Finally,the failure preventive measures were put forward from two aspects of fan configuration and wind net adjustment.
