不銹鋼(gang)齒(chi)輪 泵在具體的(de)使(shi)(shi)用中產生重要的(de)性能(neng)，在中采用定的(de)結(jie)構和性能(neng)，按照定的(de)使(shi)(shi)用方(fang)式進行和原理(li)進行工作和使(shi)(shi)用，能(neng)夠在液(ye)體的(de)運(yun)輸中發揮良好的(de)特點和性能(neng)，下面(mian)介紹下不銹鋼(gang)齒(chi)輪 泵的(de)結(jie)構和性能(neng)，在使(shi)(shi)用中需要注意的(de)事項等：

　　1.不(bu)銹鋼 泵(beng)的(de)(de)(de)作(zuo)用：將汽(qi)(qi)(qi)(qi)油(you)(you)(you)(you)從(cong)油(you)(you)(you)(you)箱中吸出，供(gong)給燃油(you)(you)(you)(you)系統(tong)足夠的(de)(de)(de)具有規定壓力的(de)(de)(de)汽(qi)(qi)(qi)(qi)油(you)(you)(you)(you)。電控汽(qi)(qi)(qi)(qi)油(you)(you)(you)(you)噴(pen)射系統(tong)壓力般為：多點噴(pen)射：0.25～0.35Mpa;單點噴(pen)射：0.1Mpa。渦(wo)輪式不(bu)銹鋼齒輪 泵(beng)主要由渦(wo)輪、殼體和泵(beng)蓋等組成。渦(wo)輪由電動(dong)機(ji)驅(qu)動(dong)，在離心力的(de)(de)(de)作(zuo)用下，渦(wo)輪緊貼殼體，將汽(qi)(qi)(qi)(qi)油(you)(you)(you)(you)經窄小縫隙由進油(you)(you)(you)(you)側驅(qu)至出油(you)(you)(you)(you)側從(cong)而加(jia)壓，燃油(you)(you)(you)(you)通過電動(dong)機(ji)的(de)(de)(de)內部起到冷卻的(de)(de)(de)作(zuo)用電動(dong)機(ji)的(de)(de)(de)作(zuo)用。

　　2.安裝位置：不銹鋼泵的(de)安(an)裝(zhuang)位置主要有兩種，即安(an)裝(zhuang)在(zai)供油(you)(you)(you)(you)(you)(you)管路中(zhong)和安(an)裝(zhuang)在(zai)汽(qi)(qi)(qi)(qi)(qi)(qi)(qi)油(you)(you)(you)(you)(you)(you)箱(xiang)內(nei)。但后(hou)者應用(yong)非常(chang)廣泛，電動(dong)汽(qi)(qi)(qi)(qi)(qi)(qi)(qi)油(you)(you)(you)(you)(you)(you)泵(beng)(beng)通常(chang)用(yong)固定(ding)在(zai)油(you)(you)(you)(you)(you)(you)箱(xiang)上的(de)油(you)(you)(you)(you)(you)(you)泵(beng)(beng)支架垂直地懸掛在(zai)油(you)(you)(you)(you)(you)(you)箱(xiang)內(nei)。雙級不(bu)銹鋼 齒輪 泵(beng)(beng)在(zai)使用(yong)中(zhong)需要注意些事項和方(fang)法(fa)，由于(yu)汽(qi)(qi)(qi)(qi)(qi)(qi)(qi)油(you)(you)(you)(you)(you)(you)極(ji)易揮發，加上泵(beng)(beng)工作時(shi)(shi)溫度升高(gao)和吸油(you)(you)(you)(you)(you)(you)時(shi)(shi)產生局部真空(kong)，使汽(qi)(qi)(qi)(qi)(qi)(qi)(qi)油(you)(you)(you)(you)(you)(you)的(de)汽(qi)(qi)(qi)(qi)(qi)(qi)(qi)化，泵(beng)(beng)油(you)(you)(you)(you)(you)(you)量減(jian)少，導致(zhi)輸(shu)出(chu)油(you)(you)(you)(you)(you)(you)壓(ya)波動(dong)。在(zai)現(xian)代汽(qi)(qi)(qi)(qi)(qi)(qi)(qi)車上廣泛采用(yong)雙級電動(dong)汽(qi)(qi)(qi)(qi)(qi)(qi)(qi)油(you)(you)(you)(you)(you)(you)泵(beng)(beng)，即由兩個電動(dong)汽(qi)(qi)(qi)(qi)(qi)(qi)(qi)油(you)(you)(you)(you)(you)(you)泵(beng)(beng)串聯，使供油(you)(you)(you)(you)(you)(you)能(neng)力(li)提高(gao)。當輸(shu)油(you)(you)(you)(you)(you)(you)管路發生堵(du)塞(sai)或汽(qi)(qi)(qi)(qi)(qi)(qi)(qi)油(you)(you)(you)(you)(you)(you)濾(lv)清器(qi)堵(du)塞(sai)時(shi)(shi)，汽(qi)(qi)(qi)(qi)(qi)(qi)(qi)油(you)(you)(you)(you)(you)(you)壓(ya)力(li)超過規定(ding)值，限壓(ya)閥打開，汽(qi)(qi)(qi)(qi)(qi)(qi)(qi)油(you)(you)(you)(you)(you)(you)流回進油(you)(you)(you)(you)(you)(you)側(ce)。發動(dong)機熄火(huo)后(hou)，單向閥關閉，避免輸(shu)油(you)(you)(you)(you)(you)(you)管路中(zhong)的(de)汽(qi)(qi)(qi)(qi)(qi)(qi)(qi)油(you)(you)(you)(you)(you)(you)倒流，保持油(you)(you)(you)(you)(you)(you)路中(zhong)有定(ding)的(de)殘(can)余壓(ya)力(li)，以(yi)便(bian)于(yu)發動(dong)機再起(qi)動(dong)。
