针对KJZ型主通风机在线监控系统在实际运用中出现的引压管路易冰冻堵塞、倒机复杂等缺点,设计了风压接线盒,解决引压管冰冻堵塞问题;编制了“一键倒机”程序,简化倒机操作步骤。在软件中加入了对变频器监控的子程序,并解决了变频器谐波干扰的问题。经过应用表明此改进保证了通风机在线监测系统的稳定性、可靠性和提高了系统的可操作性。
In view of the shortcomings of easy-freezing piping and complicated inverter in the practical application of KJZ-type main fan on-line monitoring system, the air pressure junction box was designed to solve the problem of freezing and clogging of the pilot tube. Machine "procedures, simplifying the operation steps down. In the software added to the inverter monitoring subroutine, and solve the problem of harmonic interference of the inverter. The application indicates that this improvement ensures the stability and reliability of the on-line monitoring system of the fan and improves the operability of the system.
