CPC膜片差压计由于单向过载性能差,使用中膜片经常损坏,如对其稍加改造,则可使仪表正常运行。我们曾对7台差压计进行改造,使用两年多以来,还未因元件损坏而停运。改造的关键是用CEB膜盒取代原膜片。先将正负压容室分别扩大加深,负容室内车丝装上一个过渡接头,再将装配好铁芯的膜合拧上,装入的铁芯深度应基本与改造前插入深度相同,以便调整。原负容室内排污孔 The diaphragm differential pressure gauge due to the one-way overload performance is poor, the use of the diaphragm is often damaged, as a slight modification of it, you can make the instrument normal operation. We had to transform seven differential pressure gauge, the use of more than two years, has not stopped due to component damage. The key to transformation is to replace the original diaphragm with CEB diaphragm. First positive and negative pressure chamber were expanded and deepened, respectively, negative capacity indoor wire fitted with a transition joint, and then assembled the iron core film on the screw, the depth of the iron core should be basically the same as before the transformation into the same depth, in order to Adjustment. The original negative chamber indoor sewage hole
