變頻器、壓力變送器構(gòu)成壓力閉環(huán)系統(tǒng)，自動按需降低氫壓縮機轉(zhuǎn)速調(diào)節(jié)供氣壓力，達到壓縮機經(jīng)濟運行。考慮在儲氣罐上安裝一只壓力變送器，將壓力信號反饋到變頻器的端子上，構(gòu)成恒壓供氣系統(tǒng)，供氣壓力設(shè)置為0.8MPa。

氫壓縮機電動機的額定電流應(yīng)等于或小于恒轉(zhuǎn)矩變頻器額定電流。變頻器要有內(nèi)置PID調(diào)節(jié)器和4～20mA模擬信號接口。本例選用一臺森蘭SB70G132變頻器，壓力變送氣選用森納斯DG13W=BZ-A，1.6MPa。恒壓供氣原理圖如圖2所示：

圖中：由壓力傳感器PT從貯氣罐取出壓力反饋信號，送至變頻器內(nèi)部PID調(diào)節(jié)器的輸入端，與預(yù)置的壓力給定信號相比較，經(jīng)PID調(diào)節(jié)器處理后，從而決定電動機的工作頻率和轉(zhuǎn)速。此種控制方式在保證儲氣罐氫氣的壓力始終保持恒定的前提下，在用氣量改變時自動調(diào)節(jié)電動機轉(zhuǎn)速，保持率運轉(zhuǎn)實現(xiàn)節(jié)能。
