一、汽車機油泵壞了癥狀有哪些

機(ji)(ji)油泵(beng)(beng)是汽車發(fa)動機(ji)(ji)的(de)重(zhong)要(yao)(yao)組成部分，出現故障的(de)話會影(ying)響汽車的(de)正常使用(yong)，在使用(yong)車輛的(de)過程中，當機(ji)(ji)油泵(beng)(beng)受損(sun)后(hou)，就會造成氣(qi)缸無(wu)法起(qi)到(dao)潤滑作(zuo)用(yong)，導(dao)致(zhi)發(fa)動機(ji)(ji)不(bu)能正常工作(zuo)，具體的(de)癥(zheng)狀(zhuang)(zhuang)表現有(you)(you)：1、發(fa)動機(ji)(ji)有(you)(you)明(ming)(ming)顯刺耳的(de)異(yi)常響聲。2、發(fa)動機(ji)(ji)故障燈亮(liang)起(qi)。3、油壓表上(shang)面的(de)油壓明(ming)(ming)顯偏(pian)低。4、發(fa)動機(ji)(ji)有(you)(you)嚴重(zhong)的(de)抖動。5、排氣(qi)管冒(mao)黑(hei)煙。6、車輛啟動困難(nan)，還(huan)需要(yao)(yao)長時間去擰動鑰匙。如(ru)果出現以上(shang)癥(zheng)狀(zhuang)(zhuang)，說明(ming)(ming)可能機(ji)(ji)油泵(beng)(beng)損(sun)壞，應及時進行檢(jian)修，以免(mian)導(dao)致(zhi)發(fa)動機(ji)(ji)進一步受損(sun)。

二、機油泵的作用是什么

機(ji)(ji)油(you)(you)(you)泵的作用(yong)是將油(you)(you)(you)底(di)殼里(li)的機(ji)(ji)油(you)(you)(you)經過(guo)增壓后壓送到(dao)機(ji)(ji)油(you)(you)(you)濾(lv)清器和各(ge)潤滑(hua)(hua)油(you)(you)(you)道(dao)，以(yi)潤滑(hua)(hua)發(fa)(fa)動(dong)機(ji)(ji)的各(ge)主要運動(dong)機(ji)(ji)件(jian)，并(bing)使機(ji)(ji)油(you)(you)(you)得到(dao)濾(lv)清，發(fa)(fa)動(dong)機(ji)(ji)工作時，機(ji)(ji)油(you)(you)(you)泵不斷工作，從而保(bao)證機(ji)(ji)油(you)(you)(you)在潤滑(hua)(hua)油(you)(you)(you)路中不斷循環。在發(fa)(fa)動(dong)機(ji)(ji)各(ge)種(zhong)工況下，機(ji)(ji)油(you)(you)(you)泵都(dou)應保(bao)證供(gong)給足夠(gou)的潤滑(hua)(hua)油(you)(you)(you)。沒有(you)機(ji)(ji)油(you)(you)(you)泵，機(ji)(ji)油(you)(you)(you)很難從油(you)(you)(you)底(di)殼到(dao)達(da)各(ge)摩擦部件(jian)，其潤滑(hua)(hua)作用(yong)就(jiu)無法有(you)效發(fa)(fa)揮。簡(jian)單來說，機(ji)(ji)油(you)(you)(you)泵就(jiu)相(xiang)當于汽車潤滑(hua)(hua)系統(tong)的心(xin)臟，將機(ji)(ji)油(you)(you)(you)泵送到(dao)潤滑(hua)(hua)系統(tong)的各(ge)個部件(jian)。

三、機油泵的工作原理

汽車機(ji)(ji)(ji)油(you)(you)(you)泵(beng)(beng)有兩(liang)種結構：1、齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)式機(ji)(ji)(ji)油(you)(you)(you)泵(beng)(beng)由兩(liang)個相同(tong)的(de)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)及泵(beng)(beng)殼(ke)組成，具體(ti)零部件包括(kuo)端蓋(gai)、油(you)(you)(you)泵(beng)(beng)驅動(dong)(dong)(dong)(dong)軸、外(wai)殼(ke)、從(cong)動(dong)(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)、從(cong)動(dong)(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)軸、主(zhu)動(dong)(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)、限壓(ya)(ya)閥以及驅動(dong)(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)等。當發動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)工作時(shi)，凸輪(lun)(lun)軸上(shang)的(de)驅動(dong)(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)帶(dai)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)油(you)(you)(you)泵(beng)(beng)的(de)傳動(dong)(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)，使(shi)固(gu)定在主(zhu)動(dong)(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)軸上(shang)的(de)主(zhu)動(dong)(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)旋(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)，帶(dai)動(dong)(dong)(dong)(dong)從(cong)動(dong)(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)作反方向(xiang)的(de)旋(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)，將機(ji)(ji)(ji)油(you)(you)(you)從(cong)進(jin)油(you)(you)(you)腔(qiang)(qiang)沿(yan)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)隙與泵(beng)(beng)壁送(song)(song)至出(chu)(chu)油(you)(you)(you)腔(qiang)(qiang)。進(jin)油(you)(you)(you)腔(qiang)(qiang)處便(bian)形(xing)成低壓(ya)(ya)產生吸(xi)力(li)，把(ba)油(you)(you)(you)底(di)殼(ke)內的(de)機(ji)(ji)(ji)油(you)(you)(you)吸(xi)進(jin)油(you)(you)(you)腔(qiang)(qiang)，由于主(zhu)、從(cong)動(dong)(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)不斷(duan)地旋(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)，機(ji)(ji)(ji)油(you)(you)(you)便(bian)不斷(duan)地被(bei)壓(ya)(ya)送(song)(song)到需要(yao)的(de)部位。2、轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)式機(ji)(ji)(ji)油(you)(you)(you)泵(beng)(beng)由殼(ke)體(ti)、內轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)、外(wai)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)和泵(beng)(beng)蓋(gai)等組成，內轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)用鍵或銷(xiao)子(zi)(zi)(zi)(zi)固(gu)定在轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)軸上(shang)，由曲(qu)軸齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)直接或間(jian)(jian)接驅動(dong)(dong)(dong)(dong)，轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)式機(ji)(ji)(ji)油(you)(you)(you)泵(beng)(beng)的(de)內、外(wai)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)是同(tong)向(xiang)不同(tong)步(bu)的(de)旋(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)，轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)形(xing)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)廓設計得(de)使(shi)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)到任何角度時(shi)，內、外(wai)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)每(mei)個齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)的(de)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)形(xing)廓線上(shang)總(zong)能(neng)互相成點接觸。這(zhe)(zhe)樣(yang)內、外(wai)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)間(jian)(jian)形(xing)成4個工作腔(qiang)(qiang)，隨著轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)的(de)轉(zhuan)(zhuan)(zhuan)(zhuan)動(dong)(dong)(dong)(dong)，這(zhe)(zhe)4個工作腔(qiang)(qiang)的(de)容積是不斷(duan)變化(hua)的(de)。在進(jin)油(you)(you)(you)道的(de)一側(ce)空(kong)腔(qiang)(qiang)，由于轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)脫開(kai)嚙合(he)，容積逐漸增大，產生真(zhen)空(kong)，機(ji)(ji)(ji)油(you)(you)(you)被(bei)吸(xi)入，轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)繼續(xu)旋(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)，機(ji)(ji)(ji)油(you)(you)(you)被(bei)帶(dai)到出(chu)(chu)油(you)(you)(you)道的(de)一側(ce)，這(zhe)(zhe)時(shi)，轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)正好進(jin)入嚙合(he)，使(shi)這(zhe)(zhe)一空(kong)腔(qiang)(qiang)容積減(jian)小，油(you)(you)(you)壓(ya)(ya)升(sheng)高，機(ji)(ji)(ji)油(you)(you)(you)從(cong)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)間(jian)(jian)擠(ji)出(chu)(chu)并經出(chu)(chu)油(you)(you)(you)道壓(ya)(ya)送(song)(song)出(chu)(chu)去。這(zhe)(zhe)樣(yang)，隨著轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)的(de)不斷(duan)旋(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)，機(ji)(ji)(ji)油(you)(you)(you)就不斷(duan)地被(bei)吸(xi)入和壓(ya)(ya)出(chu)(chu)。

四、機油泵多少錢一個

市場上機油泵的價格主要受到其品牌、型號、適用車型等因素的影響，一般普通的在兩三百元到五六百元一個，高端品牌或特殊型號的機油泵價格可能更高，上千元一個的也有，由于機油泵直接影響車輛動力系統，如果用的不好會導致車的使用壽命，因此有條件的話，建議買原廠的，雖然價格貴一些，但品質更有保障，或者選擇一個靠譜的機油泵品牌廠家購買產品。
