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現(xiàn)象,唯獨(dú)D-A4VSO泵有效解決此類問(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,

且由于電容每次儲(chǔ)能是有限的,所以可防止在某些意外狀況下電磁閥發(fā)生過(guò)載燒毀。同時(shí),電容儲(chǔ)能式驅(qū)動(dòng)電路無(wú)需象其他幾種驅(qū)動(dòng)電路那樣必須通過(guò)噴油脈寬同步產(chǎn)生一個(gè)開(kāi)啟脈寬做為高壓的控制信號(hào),從而簡(jiǎn)化了電路邏輯。PWM及高端驅(qū)動(dòng)電路本設(shè)計(jì)中PWM發(fā)生芯片選用了TL494PWM芯片,其中兩路誤差放大器分別用于前后兩缸引燃與主噴的電流檢測(cè)負(fù)反饋接口,無(wú)需另外增加運(yùn)放。高端驅(qū)動(dòng)器選擇了IR公司的專用浮地驅(qū)動(dòng)芯片IR213。
