進(jìn)口BURKERT緊湊式通用型電磁閥,德國(guó)burkert通用型電磁閥,原裝BURKERT電磁閥
進(jìn)口BURKERT緊湊式通用型電磁閥即刻響應(yīng)增加的感應(yīng)壓力，推動(dòng)斜盤使排污泵排量緩緩增加，節(jié)流環(huán)（換向閥）進(jìn)口的壓力開始上升。這種作用可以維持節(jié)流環(huán)（換向閥）進(jìn)出口的壓力恒定，流量恒定，從而達(dá)到絞車速度的恒定。節(jié)流環(huán)（換向閥）進(jìn)出口的壓降 delta P 維持在10-30公斤。當(dāng)所有換向閥回到中位，負(fù)載感應(yīng)壓力釋放至油箱，排污泵負(fù)載感應(yīng)控制閥維持在相當(dāng)于或略高于設(shè)定壓降值，變量排污泵處于起始待命狀態(tài)。由于變量排污泵只根據(jù)負(fù)載感應(yīng)驅(qū)動(dòng)器的指令大小來(lái)輸出流量，負(fù)載感應(yīng)控制方式無(wú)節(jié)流發(fā)熱損耗，節(jié)能效應(yīng)明顯。正如上述例子所示，驅(qū)動(dòng)控制效果明顯改善。負(fù)載感應(yīng)控制可以保證流量控制的恒定，而不受排污泵驅(qū)動(dòng)軸速度變化的影響。如果排污泵的速度減低，負(fù)載感應(yīng)控制閥推動(dòng)斜盤增加排量，維持節(jié)流環(huán)（換向閥）的壓差，直到排量達(dá)到zui大量。
進(jìn)口BURKERT緊湊式通用型電磁閥利用過(guò)程本身的壓力或壓差來(lái)驅(qū)動(dòng)控制閥動(dòng)作，也可用．溫包式檢測(cè)元件將溫度轉(zhuǎn)換為壓力，然后驅(qū)動(dòng)控制閥動(dòng)作。其特點(diǎn)是結(jié)構(gòu)簡(jiǎn)單、操作方便，但會(huì)引起壓降，造成出口壓力的非線性，通常，穩(wěn)壓精度在10％一20％。帶指揮器作用的自力式控制閥可適用于小壓降和大流量的自力式控制場(chǎng)合，出口壓力變化范圍可小于設(shè)定壓力的10％。控制閥具有節(jié)能功能，因此，在一些控制要求不高的場(chǎng)合被廣泛應(yīng)用。自力式控制閥執(zhí)行機(jī)構(gòu)膜頭的輸入信號(hào)是控制閥前或閥后的壓力或閥兩端的壓差，或經(jīng)溫包轉(zhuǎn)換后的壓力信號(hào)。執(zhí)行機(jī)構(gòu)的結(jié)構(gòu)類似氣動(dòng)薄膜執(zhí)行機(jī)構(gòu)?？刂崎y對(duì)被控介質(zhì)有一定要求，例如，自力式壓力控制閥的被控介質(zhì)溫度應(yīng)低于某一規(guī)定值，介質(zhì)應(yīng)干凈，當(dāng)介質(zhì)溫度較高時(shí)，例如，用于蒸汽或150℃以上的液體時(shí)，應(yīng)設(shè)置冷凝器，使進(jìn)入執(zhí)行機(jī)構(gòu)比較器內(nèi)的介質(zhì)溫度低于規(guī)定值。
