基于变频器通信技术的定型机燃烧器安全设计

Safety Design of Setting Machine Burner Based on Transducer Communication Technology

定型机烘箱加热采用燃烧器加热方式,既能快速升温又能降低燃烧成本,但燃烧器必须在排风机和循环风机满足转动条件下才可启动运行;为解决燃烧器的相关安全问题,研究了由电机的反馈参数来给定燃烧器的启动条件。通过采用三菱变频器通信技术,实时监测排风机和循环风机的输出参数,并由PLC结合延迟时间判定结果,实现了闭环控制燃烧器启动,保证了定型机的安全。

The oven of setting machine was heated by burner, which not only increased the temperature rapidly but also reduced the burning cost. But the starting signal of the exhaust fan and the circulating fan were connected with the starting condition of the burner. In order to ensure the heating safety, the starting condition of the burner was studied by the feedback parameters of the mo tor. The output parameters of exhaust fan and circulating fan were monitored in real time by using MITSUBISHI transducer commu nication technology. PI.C and delay time were used to determine the results. The safety of setting machine was guaranteed through closed-loop control.
