一、齒輪油泵的特點有哪些

齒輪油泵是通過一對參數和結構相同的漸開線齒輪的相互滾動嚙合,將油箱內的低壓油升至能做功的高壓油的重要部件。那么你知道齒輪油泵的特點有哪些嗎？

1、結構緊湊，使用(yong)和保養(yang)方便。

2、具有(you)良好(hao)的自吸(xi)性(xing)，故每次開(kai)泵前無(wu)須灌入液體。

3、齒輪油泵的(de)潤(run)滑是靠輸送(song)的(de)液(ye)體而自(zi)動(dong)達(da)到的(de)，故日常工作時無須別(bie)加潤(run)滑油。

二、齒輪油泵的作用是什么

齒輪油泵的(de)的(de)作(zuo)用(yong)(yong)是用(yong)(yong)來(lai)傳送粘性比較大(da)的(de)液態(tai)(tai)，如潤滑(hua)(hua)油(you)和燃燒油(you)，不(bu)適(shi)合傳送粘性較低的(de)液態(tai)(tai)例(li)如水以(yi)及汽油(you)等等，不(bu)適(shi)合傳送帶有顆粒雜質的(de)液態(tai)(tai)影響泵(beng)的(de)使用(yong)(yong)期限，可身為(wei)潤滑(hua)(hua)系統油(you)泵(beng)和液壓系統油(you)泵(beng)，普遍用(yong)(yong)于汽車發動(dong)機、汽輪發電(dian)機、多級離心風機、數(shu)控(kong)車床以(yi)及其他(ta)設備。齒輪油(you)泵(beng)加工工藝要求高，不(bu)容易獲得(de)準確的(de)匹配以(yi)及不(bu)影響環保。

當齒(chi)輪(lun)油(you)泵積(ji)極主(zhu)動(dong)(dong)(dong)傳動(dong)(dong)(dong)齒(chi)輪(lun)旋轉，吸(xi)油(you)腔(qiang)傳動(dong)(dong)(dong)齒(chi)輪(lun)松脫(tuo)嚙合(he)，傳動(dong)(dong)(dong)齒(chi)輪(lun)的(de)傳動(dong)(dong)(dong)齒(chi)輪(lun)推出齒(chi)間(jian)，使密閉容積(ji)擴(kuo)大(da)，產生局部性真空，汽車油(you)箱中的(de)液壓油(you)在外部大(da)氣壓的(de)的(de)作用下(xia)，經(jing)吸(xi)輸油(you)管路、吸(xi)油(you)腔(qiang)進到齒(chi)間(jian)。伴隨著傳動(dong)(dong)(dong)齒(chi)輪(lun)旋轉，吸(xi)入齒(chi)間(jian)的(de)液壓油(you)被(bei)送到另一邊(bian)，進到壓油(you)腔(qiang)。

這也是傳動齒輪進到嚙(nie)合，使密閉(bi)性漸漸縮(suo)減，傳(chuan)(chuan)動(dong)(dong)(dong)齒(chi)(chi)輪間部份的(de)液壓(ya)油(you)被擠出來，產生了傳(chuan)(chuan)動(dong)(dong)(dong)齒(chi)(chi)輪的(de)壓(ya)油(you)全過(guo)程(cheng)。齒(chi)(chi)輪嚙(nie)合時(shi)齒(chi)(chi)向接觸線(xian)把(ba)吸油(you)腔和(he)壓(ya)油(you)腔分開(kai)，起配油(you)的(de)作用。當齒(chi)(chi)輪油(you)泵的(de)積(ji)極主動(dong)(dong)(dong)傳(chuan)(chuan)動(dong)(dong)(dong)齒(chi)(chi)輪有電動(dong)(dong)(dong)機帶動(dong)(dong)(dong)連續(xu)不斷旋轉時(shi)，傳(chuan)(chuan)動(dong)(dong)(dong)齒(chi)(chi)輪松脫嚙(nie)合一邊(bian)，因為密閉(bi)容積(ji)增大(da)，則(ze)連續(xu)不斷從汽(qi)車油(you)箱中吸油(you)，傳(chuan)(chuan)動(dong)(dong)(dong)齒(chi)(chi)輪進到嚙(nie)合的(de)一邊(bian)，因為密閉(bi)容積(ji)縮(suo)減則(ze)不斷排油(you)，產生一個連續(xu)不斷循環的(de)全過(guo)程(cheng)。

齒(chi)(chi)(chi)(chi)輪(lun)油泵在(zai)(zai)泵殼(ke)中配(pei)有一(yi)對旋(xuan)(xuan)轉傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)輪(lun)，一(yi)個(ge)積極主(zhu)動(dong)(dong)(dong)(dong)，一(yi)個(ge)處于(yu)被動(dong)(dong)(dong)(dong)，依靠兩傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)輪(lun)的互相嚙合(he)，把泵內的整體(ti)工作(zuo)腔(qiang)(qiang)分2個(ge)獨立的部份。A為吸(xi)(xi)入(ru)腔(qiang)(qiang)，B為排(pai)出(chu)來腔(qiang)(qiang)。齒(chi)(chi)(chi)(chi)輪(lun)油泵在(zai)(zai)運行時積極主(zhu)動(dong)(dong)(dong)(dong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)輪(lun)帶動(dong)(dong)(dong)(dong)處于(yu)被動(dong)(dong)(dong)(dong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)輪(lun)旋(xuan)(xuan)轉，當傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)輪(lun)從嚙合(he)到(dao)松脫時在(zai)(zai)吸(xi)(xi)入(ru)側A就產(chan)生(sheng)局部性真空(kong)，液(ye)(ye)態被吸(xi)(xi)入(ru)。被吸(xi)(xi)入(ru)的液(ye)(ye)態充滿傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)輪(lun)的各個(ge)齒(chi)(chi)(chi)(chi)谷而送(song)到(dao)排(pai)出(chu)來側B，傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)輪(lun)進(jin)到(dao)嚙合(he)時液(ye)(ye)態被擠出(chu)來，產(chan)生(sheng)高壓(ya)液(ye)(ye)態并經(jing)泵排(pai)出(chu)口排(pai)出(chu)來泵外。
