A4VSO泵具有泵具有噪音低、體積小、自吸能力好、可靠性高等優(yōu)點(diǎn)。在閉式系統(tǒng)上應(yīng)用，油泵變量過(guò)零位時(shí)一般柱塞泵都有托盤(pán)現(xiàn)象，唯獨(dú)D-A4VSO泵有效解決此類(lèi)問(wèn)題，因補(bǔ)油泵、控制泵可以串接、控制閥可以集成在泵蓋上，其結(jié)構(gòu)非常緊湊;另外，比例泵均帶有位移傳感器閉式反饋回路，其零位控制精度非常高。廣泛應(yīng)用于：冶金行業(yè)、鍛壓行業(yè)、船舶行業(yè)、船舶等等領(lǐng)域。A4VSO系列規(guī)格有40、71、125、180、250:;變量形式有恒壓，恒功率、液動(dòng)、負(fù)載感應(yīng)、比例、伺服、壓力流量復(fù)合控制形式;有開(kāi)式系統(tǒng)泵和閉式系統(tǒng)泵。A10-FR01B-12,A10-FR01C-12,A10-FR01H-12,

以上計(jì)算需要參考標(biāo)準(zhǔn)工況(STP)下的溫度值Ts和壓力值Ps。標(biāo)準(zhǔn)工況(STP)通常是指位于海平面上，但沒(méi)有單一標(biāo)準(zhǔn)，比如常用的標(biāo)準(zhǔn)工況有下面幾種：14.696PSIA2514.696PSIA76mmHG值得注意的是，質(zhì)量的單位通常為克、千克等，而質(zhì)量流量的單位則是SLPM(每分鐘標(biāo)準(zhǔn)升)、SCCM(每分鐘標(biāo)準(zhǔn)毫升)或SCFH(每小時(shí)標(biāo)準(zhǔn)立方英尺)。只要知道設(shè)備標(biāo)定的標(biāo)準(zhǔn)工況及被測(cè)氣體在標(biāo)準(zhǔn)工況下的密度，便可計(jì)算得出同過(guò)的氣體流量為每分鐘多少克或是每小時(shí)多少千克。
