传统锅炉给水泵连续恒速运行,依靠调节给水管道调节阀和回流支路实现水位控制的调节方法,目前已经改变为采用流量计与上位机、PLC以及变频器控制给水泵转速,共同参与锅炉给水的自动实时控制,但是流量计在其应用过程中也存在着可靠性欠佳、故障时而发生等问题,本文就其维护检修的一些经验、教训,采取的较为可靠的措施作一简述。
Traditional boiler feed pump continuous constant speed operation, relying on the regulation of the water supply pipe control valve and return branch to achieve water level control of the adjustment method, has now been changed to flow meter and host computer, PLC and inverter control to the pump speed, to participate in the boiler feed However, the flowmeter has some problems in the process of its application, such as poor reliability and malfunction. This paper gives a brief account of some of the experiences and lessons learned in maintenance and overhaul, and the more reliable measures taken.
