一、汽車機油泵壞了癥狀有哪些
機油(you)泵(beng)是汽車(che)(che)發(fa)動(dong)機的(de)(de)(de)重(zhong)要(yao)組(zu)成(cheng)部分,出現(xian)故障的(de)(de)(de)話(hua)會(hui)影響(xiang)汽車(che)(che)的(de)(de)(de)正常使用,在使用車(che)(che)輛(liang)的(de)(de)(de)過程中(zhong),當機油(you)泵(beng)受損后,就(jiu)會(hui)造成(cheng)氣(qi)缸無法起到潤滑(hua)作(zuo)用,導致(zhi)發(fa)動(dong)機不能(neng)正常工作(zuo),具體的(de)(de)(de)癥狀表(biao)現(xian)有:1、發(fa)動(dong)機有明(ming)(ming)顯刺(ci)耳的(de)(de)(de)異常響(xiang)聲。2、發(fa)動(dong)機故障燈亮(liang)起。3、油(you)壓表(biao)上面的(de)(de)(de)油(you)壓明(ming)(ming)顯偏低。4、發(fa)動(dong)機有嚴重(zhong)的(de)(de)(de)抖動(dong)。5、排氣(qi)管冒黑煙。6、車(che)(che)輛(liang)啟動(dong)困難,還需要(yao)長時間去擰(ning)動(dong)鑰(yao)匙。如果出現(xian)以(yi)上癥狀,說明(ming)(ming)可能(neng)機油(you)泵(beng)損壞,應及時進(jin)(jin)行(xing)檢修,以(yi)免導致(zhi)發(fa)動(dong)機進(jin)(jin)一步受損。
二、機油泵的作用是什么
機(ji)(ji)油(you)泵(beng)(beng)(beng)的(de)作用(yong)是將(jiang)油(you)底殼里(li)的(de)機(ji)(ji)油(you)經過增壓后壓送(song)到機(ji)(ji)油(you)濾清器(qi)和各(ge)潤滑(hua)(hua)(hua)(hua)油(you)道(dao),以潤滑(hua)(hua)(hua)(hua)發(fa)(fa)動(dong)機(ji)(ji)的(de)各(ge)主要運動(dong)機(ji)(ji)件(jian),并使機(ji)(ji)油(you)得到濾清,發(fa)(fa)動(dong)機(ji)(ji)工(gong)作時,機(ji)(ji)油(you)泵(beng)(beng)(beng)不(bu)斷工(gong)作,從(cong)而保(bao)證機(ji)(ji)油(you)在(zai)潤滑(hua)(hua)(hua)(hua)油(you)路中不(bu)斷循環。在(zai)發(fa)(fa)動(dong)機(ji)(ji)各(ge)種工(gong)況下,機(ji)(ji)油(you)泵(beng)(beng)(beng)都應保(bao)證供給足(zu)夠(gou)的(de)潤滑(hua)(hua)(hua)(hua)油(you)。沒有(you)機(ji)(ji)油(you)泵(beng)(beng)(beng),機(ji)(ji)油(you)很難(nan)從(cong)油(you)底殼到達各(ge)摩擦部件(jian),其潤滑(hua)(hua)(hua)(hua)作用(yong)就(jiu)無法有(you)效發(fa)(fa)揮(hui)。簡(jian)單來說,機(ji)(ji)油(you)泵(beng)(beng)(beng)就(jiu)相當于汽車潤滑(hua)(hua)(hua)(hua)系(xi)(xi)統的(de)心臟,將(jiang)機(ji)(ji)油(you)泵(beng)(beng)(beng)送(song)到潤滑(hua)(hua)(hua)(hua)系(xi)(xi)統的(de)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)(beng)有兩種結構(gou):1、齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)式機(ji)(ji)(ji)油(you)(you)(you)泵(beng)(beng)(beng)由兩個(ge)(ge)相同的(de)(de)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)及泵(beng)(beng)(beng)殼(ke)組成(cheng),具體(ti)零部(bu)件包括端(duan)蓋(gai)、油(you)(you)(you)泵(beng)(beng)(beng)驅(qu)動(dong)(dong)(dong)軸(zhou)、外(wai)殼(ke)、從(cong)(cong)動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)、從(cong)(cong)動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)軸(zhou)、主動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)、限壓(ya)閥以及驅(qu)動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)等。當發(fa)動(dong)(dong)(dong)機(ji)(ji)(ji)工作時(shi),凸輪(lun)(lun)(lun)軸(zhou)上的(de)(de)驅(qu)動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)帶動(dong)(dong)(dong)機(ji)(ji)(ji)油(you)(you)(you)泵(beng)(beng)(beng)的(de)(de)傳動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun),使固定在(zai)主動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)軸(zhou)上的(de)(de)主動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)旋(xuan)轉(zhuan)(zhuan),帶動(dong)(dong)(dong)從(cong)(cong)動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)作反方(fang)向的(de)(de)旋(xuan)轉(zhuan)(zhuan),將機(ji)(ji)(ji)油(you)(you)(you)從(cong)(cong)進(jin)(jin)油(you)(you)(you)腔(qiang)(qiang)(qiang)沿齒(chi)(chi)(chi)(chi)(chi)(chi)隙與泵(beng)(beng)(beng)壁(bi)送至出(chu)(chu)油(you)(you)(you)腔(qiang)(qiang)(qiang)。進(jin)(jin)油(you)(you)(you)腔(qiang)(qiang)(qiang)處便形(xing)成(cheng)低壓(ya)產生吸(xi)力,把油(you)(you)(you)底殼(ke)內(nei)的(de)(de)機(ji)(ji)(ji)油(you)(you)(you)吸(xi)進(jin)(jin)油(you)(you)(you)腔(qiang)(qiang)(qiang),由于(yu)主、從(cong)(cong)動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)不(bu)(bu)(bu)(bu)斷(duan)地旋(xuan)轉(zhuan)(zhuan),機(ji)(ji)(ji)油(you)(you)(you)便不(bu)(bu)(bu)(bu)斷(duan)地被(bei)壓(ya)送到需要的(de)(de)部(bu)位。2、轉(zhuan)(zhuan)子(zi)式機(ji)(ji)(ji)油(you)(you)(you)泵(beng)(beng)(beng)由殼(ke)體(ti)、內(nei)轉(zhuan)(zhuan)子(zi)、外(wai)轉(zhuan)(zhuan)子(zi)和(he)泵(beng)(beng)(beng)蓋(gai)等組成(cheng),內(nei)轉(zhuan)(zhuan)子(zi)用鍵或(huo)銷子(zi)固定在(zai)轉(zhuan)(zhuan)子(zi)軸(zhou)上,由曲軸(zhou)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)直接或(huo)間(jian)(jian)接驅(qu)動(dong)(dong)(dong),轉(zhuan)(zhuan)子(zi)式機(ji)(ji)(ji)油(you)(you)(you)泵(beng)(beng)(beng)的(de)(de)內(nei)、外(wai)轉(zhuan)(zhuan)子(zi)是(shi)同向不(bu)(bu)(bu)(bu)同步的(de)(de)旋(xuan)轉(zhuan)(zhuan),轉(zhuan)(zhuan)子(zi)齒(chi)(chi)(chi)(chi)(chi)(chi)形(xing)齒(chi)(chi)(chi)(chi)(chi)(chi)廓設計得(de)使轉(zhuan)(zhuan)子(zi)轉(zhuan)(zhuan)到任何(he)角(jiao)度時(shi),內(nei)、外(wai)轉(zhuan)(zhuan)子(zi)每個(ge)(ge)齒(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)齒(chi)(chi)(chi)(chi)(chi)(chi)形(xing)廓線上總能互相成(cheng)點接觸。這(zhe)樣(yang)內(nei)、外(wai)轉(zhuan)(zhuan)子(zi)間(jian)(jian)形(xing)成(cheng)4個(ge)(ge)工作腔(qiang)(qiang)(qiang),隨著(zhu)轉(zhuan)(zhuan)子(zi)的(de)(de)轉(zhuan)(zhuan)動(dong)(dong)(dong),這(zhe)4個(ge)(ge)工作腔(qiang)(qiang)(qiang)的(de)(de)容(rong)(rong)積是(shi)不(bu)(bu)(bu)(bu)斷(duan)變化的(de)(de)。在(zai)進(jin)(jin)油(you)(you)(you)道的(de)(de)一(yi)側(ce)(ce)空(kong)腔(qiang)(qiang)(qiang),由于(yu)轉(zhuan)(zhuan)子(zi)脫(tuo)開(kai)嚙合,容(rong)(rong)積逐漸增大,產生真空(kong),機(ji)(ji)(ji)油(you)(you)(you)被(bei)吸(xi)入(ru),轉(zhuan)(zhuan)子(zi)繼續(xu)旋(xuan)轉(zhuan)(zhuan),機(ji)(ji)(ji)油(you)(you)(you)被(bei)帶到出(chu)(chu)油(you)(you)(you)道的(de)(de)一(yi)側(ce)(ce),這(zhe)時(shi),轉(zhuan)(zhuan)子(zi)正好(hao)進(jin)(jin)入(ru)嚙合,使這(zhe)一(yi)空(kong)腔(qiang)(qiang)(qiang)容(rong)(rong)積減(jian)小,油(you)(you)(you)壓(ya)升高,機(ji)(ji)(ji)油(you)(you)(you)從(cong)(cong)齒(chi)(chi)(chi)(chi)(chi)(chi)間(jian)(jian)擠出(chu)(chu)并經出(chu)(chu)油(you)(you)(you)道壓(ya)送出(chu)(chu)去。這(zhe)樣(yang),隨著(zhu)轉(zhuan)(zhuan)子(zi)的(de)(de)不(bu)(bu)(bu)(bu)斷(duan)旋(xuan)轉(zhuan)(zhuan),機(ji)(ji)(ji)油(you)(you)(you)就(jiu)不(bu)(bu)(bu)(bu)斷(duan)地被(bei)吸(xi)入(ru)和(he)壓(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。
