我厂甲醇生产用水煤气柜距造气岗位较远,设计时我们采用双管齐下的办法,即:①用膜片差压计CPC-2.5A和XCT-103连续指示气柜高度,并带上下限越限报警;②在气柜上装设信号开关,与XCT-103接点并联,越限时可靠地发出报警信号。膜片差压计安装的方法刊物上已有报道,不多赘述。这里仅就一些计算,介绍我们的意见,供大家参考。
Methanol production of water from the gas station I gas station farther away from the design, we use a two-pronged approach, namely: ① with diaphragm differential pressure gauge CPC-2.5A and XCT-103 continuous indication of gas tank height, and bring the lower limit of the more Limit alarm; ② installed in the gas tank signal switch, in parallel with the XCT-103 contacts, over-limit reliably send alarm signal. Diaphragm differential pressure method of installation of the publication has been reported, not repeat them. Here only some calculations, introduce our opinions for your reference.
