一、汽車機油泵壞了癥狀有哪些
機(ji)油(you)泵是汽(qi)車(che)(che)發(fa)動機(ji)的(de)(de)重(zhong)要(yao)組成(cheng)部分,出現故障的(de)(de)話會(hui)影(ying)響汽(qi)車(che)(che)的(de)(de)正常使(shi)用,在使(shi)用車(che)(che)輛的(de)(de)過程(cheng)中,當機(ji)油(you)泵受損后(hou),就會(hui)造成(cheng)氣缸無法起到潤滑(hua)作(zuo)用,導致發(fa)動機(ji)不能(neng)正常工(gong)作(zuo),具體的(de)(de)癥狀表(biao)現有(you):1、發(fa)動機(ji)有(you)明顯刺耳的(de)(de)異常響聲。2、發(fa)動機(ji)故障燈亮(liang)起。3、油(you)壓(ya)表(biao)上(shang)面的(de)(de)油(you)壓(ya)明顯偏低。4、發(fa)動機(ji)有(you)嚴重(zhong)的(de)(de)抖動。5、排氣管冒黑煙。6、車(che)(che)輛啟動困難,還需要(yao)長時(shi)間(jian)去擰動鑰匙。如(ru)果出現以(yi)上(shang)癥狀,說明可能(neng)機(ji)油(you)泵損壞(huai),應及時(shi)進行檢(jian)修,以(yi)免(mian)導致發(fa)動機(ji)進一步受損。
二、機油泵的作用是什么
機(ji)(ji)(ji)油(you)(you)(you)泵(beng)的(de)(de)作(zuo)用是將(jiang)油(you)(you)(you)底殼里的(de)(de)機(ji)(ji)(ji)油(you)(you)(you)經過(guo)增壓后壓送(song)到機(ji)(ji)(ji)油(you)(you)(you)濾清(qing)器和各(ge)潤(run)滑(hua)油(you)(you)(you)道(dao),以潤(run)滑(hua)發動(dong)機(ji)(ji)(ji)的(de)(de)各(ge)主要運動(dong)機(ji)(ji)(ji)件,并使機(ji)(ji)(ji)油(you)(you)(you)得到濾清(qing),發動(dong)機(ji)(ji)(ji)工(gong)作(zuo)時,機(ji)(ji)(ji)油(you)(you)(you)泵(beng)不斷工(gong)作(zuo),從而(er)保(bao)(bao)證(zheng)機(ji)(ji)(ji)油(you)(you)(you)在潤(run)滑(hua)油(you)(you)(you)路中不斷循環(huan)。在發動(dong)機(ji)(ji)(ji)各(ge)種(zhong)工(gong)況下,機(ji)(ji)(ji)油(you)(you)(you)泵(beng)都應保(bao)(bao)證(zheng)供給足夠的(de)(de)潤(run)滑(hua)油(you)(you)(you)。沒有機(ji)(ji)(ji)油(you)(you)(you)泵(beng),機(ji)(ji)(ji)油(you)(you)(you)很難(nan)從油(you)(you)(you)底殼到達各(ge)摩(mo)擦(ca)部件,其潤(run)滑(hua)作(zuo)用就(jiu)無法有效發揮。簡單來說,機(ji)(ji)(ji)油(you)(you)(you)泵(beng)就(jiu)相當于汽車潤(run)滑(hua)系統的(de)(de)心臟(zang),將(jiang)機(ji)(ji)(ji)油(you)(you)(you)泵(beng)送(song)到潤(run)滑(hua)系統的(de)(de)各(ge)個部件。
三、機油泵的工作原理
汽車機(ji)(ji)(ji)油(you)(you)(you)(you)泵(beng)(beng)(beng)有兩種結構(gou):1、齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)式機(ji)(ji)(ji)油(you)(you)(you)(you)泵(beng)(beng)(beng)由兩個(ge)相同(tong)的(de)(de)(de)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)及(ji)泵(beng)(beng)(beng)殼(ke)組成(cheng)(cheng),具體零部(bu)件包括端蓋、油(you)(you)(you)(you)泵(beng)(beng)(beng)驅動(dong)(dong)(dong)軸(zhou)、外殼(ke)、從(cong)(cong)動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)、從(cong)(cong)動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)軸(zhou)、主動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)、限壓(ya)閥以及(ji)驅動(dong)(dong)(dong)齒(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(shang)(shang)(shang)的(de)(de)(de)驅動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)帶(dai)動(dong)(dong)(dong)機(ji)(ji)(ji)油(you)(you)(you)(you)泵(beng)(beng)(beng)的(de)(de)(de)傳動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun),使(shi)固定在主動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)軸(zhou)上(shang)(shang)(shang)的(de)(de)(de)主動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)旋(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan),帶(dai)動(dong)(dong)(dong)從(cong)(cong)動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)作反方向(xiang)的(de)(de)(de)旋(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan),將機(ji)(ji)(ji)油(you)(you)(you)(you)從(cong)(cong)進油(you)(you)(you)(you)腔(qiang)(qiang)(qiang)沿齒(chi)(chi)(chi)(chi)(chi)隙與泵(beng)(beng)(beng)壁送至出(chu)油(you)(you)(you)(you)腔(qiang)(qiang)(qiang)。進油(you)(you)(you)(you)腔(qiang)(qiang)(qiang)處便形成(cheng)(cheng)低壓(ya)產(chan)(chan)生吸力(li),把油(you)(you)(you)(you)底(di)殼(ke)內(nei)(nei)的(de)(de)(de)機(ji)(ji)(ji)油(you)(you)(you)(you)吸進油(you)(you)(you)(you)腔(qiang)(qiang)(qiang),由于(yu)主、從(cong)(cong)動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)不(bu)斷(duan)地旋(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan),機(ji)(ji)(ji)油(you)(you)(you)(you)便不(bu)斷(duan)地被壓(ya)送到(dao)需要的(de)(de)(de)部(bu)位。2、轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)式機(ji)(ji)(ji)油(you)(you)(you)(you)泵(beng)(beng)(beng)由殼(ke)體、內(nei)(nei)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)、外轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)和泵(beng)(beng)(beng)蓋等組成(cheng)(cheng),內(nei)(nei)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)用鍵或銷子(zi)(zi)固定在轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)軸(zhou)上(shang)(shang)(shang),由曲軸(zhou)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)直接(jie)(jie)或間(jian)接(jie)(jie)驅動(dong)(dong)(dong),轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)式機(ji)(ji)(ji)油(you)(you)(you)(you)泵(beng)(beng)(beng)的(de)(de)(de)內(nei)(nei)、外轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)是同(tong)向(xiang)不(bu)同(tong)步(bu)的(de)(de)(de)旋(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan),轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)齒(chi)(chi)(chi)(chi)(chi)形齒(chi)(chi)(chi)(chi)(chi)廓(kuo)設計(ji)得使(shi)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)到(dao)任何角度(du)時(shi),內(nei)(nei)、外轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)每個(ge)齒(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)齒(chi)(chi)(chi)(chi)(chi)形廓(kuo)線(xian)上(shang)(shang)(shang)總能互相成(cheng)(cheng)點接(jie)(jie)觸。這樣內(nei)(nei)、外轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)間(jian)形成(cheng)(cheng)4個(ge)工作腔(qiang)(qiang)(qiang),隨著轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)的(de)(de)(de)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)動(dong)(dong)(dong),這4個(ge)工作腔(qiang)(qiang)(qiang)的(de)(de)(de)容積(ji)是不(bu)斷(duan)變化(hua)的(de)(de)(de)。在進油(you)(you)(you)(you)道(dao)的(de)(de)(de)一側空腔(qiang)(qiang)(qiang),由于(yu)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)脫開嚙合(he),容積(ji)逐漸增大,產(chan)(chan)生真空,機(ji)(ji)(ji)油(you)(you)(you)(you)被吸入,轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)繼(ji)續旋(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan),機(ji)(ji)(ji)油(you)(you)(you)(you)被帶(dai)到(dao)出(chu)油(you)(you)(you)(you)道(dao)的(de)(de)(de)一側,這時(shi),轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)正好(hao)進入嚙合(he),使(shi)這一空腔(qiang)(qiang)(qiang)容積(ji)減小(xiao),油(you)(you)(you)(you)壓(ya)升高,機(ji)(ji)(ji)油(you)(you)(you)(you)從(cong)(cong)齒(chi)(chi)(chi)(chi)(chi)間(jian)擠出(chu)并經出(chu)油(you)(you)(you)(you)道(dao)壓(ya)送出(chu)去。這樣,隨著轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)的(de)(de)(de)不(bu)斷(duan)旋(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan),機(ji)(ji)(ji)油(you)(you)(you)(you)就不(bu)斷(duan)地被吸入和壓(ya)出(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。
