一、汽車機油泵壞了癥狀有哪些
機(ji)油(you)泵(beng)是汽(qi)車(che)(che)發(fa)動(dong)(dong)(dong)(dong)機(ji)的(de)重要(yao)組成(cheng)部分(fen),出現(xian)故障的(de)話會影響汽(qi)車(che)(che)的(de)正常使(shi)用,在使(shi)用車(che)(che)輛(liang)的(de)過(guo)程中,當機(ji)油(you)泵(beng)受(shou)損(sun)后,就(jiu)會造(zao)成(cheng)氣(qi)缸無法起(qi)到潤(run)滑作(zuo)用,導(dao)致(zhi)(zhi)發(fa)動(dong)(dong)(dong)(dong)機(ji)不能正常工作(zuo),具體的(de)癥(zheng)狀表現(xian)有:1、發(fa)動(dong)(dong)(dong)(dong)機(ji)有明(ming)顯(xian)刺耳的(de)異常響聲(sheng)。2、發(fa)動(dong)(dong)(dong)(dong)機(ji)故障燈(deng)亮起(qi)。3、油(you)壓表上面的(de)油(you)壓明(ming)顯(xian)偏低。4、發(fa)動(dong)(dong)(dong)(dong)機(ji)有嚴重的(de)抖(dou)動(dong)(dong)(dong)(dong)。5、排氣(qi)管冒黑煙。6、車(che)(che)輛(liang)啟動(dong)(dong)(dong)(dong)困難,還需要(yao)長時間(jian)去擰動(dong)(dong)(dong)(dong)鑰匙。如果出現(xian)以上癥(zheng)狀,說明(ming)可能機(ji)油(you)泵(beng)損(sun)壞,應及時進行檢(jian)修,以免導(dao)致(zhi)(zhi)發(fa)動(dong)(dong)(dong)(dong)機(ji)進一步受(shou)損(sun)。
二、機油泵的作用是什么
機(ji)(ji)(ji)(ji)(ji)(ji)油(you)(you)(you)(you)泵(beng)的(de)(de)作(zuo)用是將(jiang)油(you)(you)(you)(you)底殼里的(de)(de)機(ji)(ji)(ji)(ji)(ji)(ji)油(you)(you)(you)(you)經過增壓(ya)后(hou)壓(ya)送到機(ji)(ji)(ji)(ji)(ji)(ji)油(you)(you)(you)(you)濾(lv)清器和(he)各(ge)(ge)(ge)潤(run)滑油(you)(you)(you)(you)道,以潤(run)滑發(fa)動(dong)(dong)機(ji)(ji)(ji)(ji)(ji)(ji)的(de)(de)各(ge)(ge)(ge)主(zhu)要運動(dong)(dong)機(ji)(ji)(ji)(ji)(ji)(ji)件,并使機(ji)(ji)(ji)(ji)(ji)(ji)油(you)(you)(you)(you)得到濾(lv)清,發(fa)動(dong)(dong)機(ji)(ji)(ji)(ji)(ji)(ji)工作(zuo)時,機(ji)(ji)(ji)(ji)(ji)(ji)油(you)(you)(you)(you)泵(beng)不(bu)斷工作(zuo),從而保證(zheng)機(ji)(ji)(ji)(ji)(ji)(ji)油(you)(you)(you)(you)在(zai)潤(run)滑油(you)(you)(you)(you)路中(zhong)不(bu)斷循(xun)環。在(zai)發(fa)動(dong)(dong)機(ji)(ji)(ji)(ji)(ji)(ji)各(ge)(ge)(ge)種工況下,機(ji)(ji)(ji)(ji)(ji)(ji)油(you)(you)(you)(you)泵(beng)都(dou)應保證(zheng)供給足夠(gou)的(de)(de)潤(run)滑油(you)(you)(you)(you)。沒(mei)有機(ji)(ji)(ji)(ji)(ji)(ji)油(you)(you)(you)(you)泵(beng),機(ji)(ji)(ji)(ji)(ji)(ji)油(you)(you)(you)(you)很難從油(you)(you)(you)(you)底殼到達各(ge)(ge)(ge)摩擦(ca)部件,其潤(run)滑作(zuo)用就(jiu)無法有效(xiao)發(fa)揮。簡單來說,機(ji)(ji)(ji)(ji)(ji)(ji)油(you)(you)(you)(you)泵(beng)就(jiu)相當(dang)于汽車(che)潤(run)滑系統(tong)(tong)的(de)(de)心臟,將(jiang)機(ji)(ji)(ji)(ji)(ji)(ji)油(you)(you)(you)(you)泵(beng)送到潤(run)滑系統(tong)(tong)的(de)(de)各(ge)(ge)(ge)個部件。
三、機油泵的工作原理
汽(qi)車機(ji)油(you)(you)(you)(you)(you)(you)泵(beng)(beng)(beng)有兩種(zhong)結構:1、齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)式機(ji)油(you)(you)(you)(you)(you)(you)泵(beng)(beng)(beng)由(you)兩個相同的(de)(de)(de)(de)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)及泵(beng)(beng)(beng)殼組成(cheng),具體零部(bu)件(jian)包括端蓋(gai)、油(you)(you)(you)(you)(you)(you)泵(beng)(beng)(beng)驅動(dong)(dong)(dong)軸(zhou)、外(wai)(wai)殼、從(cong)動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)、從(cong)動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)軸(zhou)、主動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)、限壓(ya)閥以及驅動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)等。當發動(dong)(dong)(dong)機(ji)工作(zuo)時(shi),凸輪(lun)(lun)軸(zhou)上(shang)(shang)(shang)的(de)(de)(de)(de)驅動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)帶動(dong)(dong)(dong)機(ji)油(you)(you)(you)(you)(you)(you)泵(beng)(beng)(beng)的(de)(de)(de)(de)傳動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun),使固定在(zai)主動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)軸(zhou)上(shang)(shang)(shang)的(de)(de)(de)(de)主動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan),帶動(dong)(dong)(dong)從(cong)動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)作(zuo)反方向的(de)(de)(de)(de)旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan),將機(ji)油(you)(you)(you)(you)(you)(you)從(cong)進油(you)(you)(you)(you)(you)(you)腔(qiang)(qiang)沿齒(chi)(chi)(chi)(chi)(chi)(chi)隙與泵(beng)(beng)(beng)壁送(song)至出(chu)(chu)(chu)油(you)(you)(you)(you)(you)(you)腔(qiang)(qiang)。進油(you)(you)(you)(you)(you)(you)腔(qiang)(qiang)處便形(xing)(xing)成(cheng)低壓(ya)產生吸(xi)力,把油(you)(you)(you)(you)(you)(you)底(di)殼內(nei)(nei)的(de)(de)(de)(de)機(ji)油(you)(you)(you)(you)(you)(you)吸(xi)進油(you)(you)(you)(you)(you)(you)腔(qiang)(qiang),由(you)于(yu)主、從(cong)動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)不(bu)斷(duan)(duan)地(di)旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan),機(ji)油(you)(you)(you)(you)(you)(you)便不(bu)斷(duan)(duan)地(di)被(bei)壓(ya)送(song)到(dao)需要(yao)的(de)(de)(de)(de)部(bu)位(wei)。2、轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)式機(ji)油(you)(you)(you)(you)(you)(you)泵(beng)(beng)(beng)由(you)殼體、內(nei)(nei)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)、外(wai)(wai)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)和泵(beng)(beng)(beng)蓋(gai)等組成(cheng),內(nei)(nei)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)用(yong)鍵或(huo)銷子(zi)(zi)(zi)固定在(zai)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)軸(zhou)上(shang)(shang)(shang),由(you)曲軸(zhou)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)直接或(huo)間接驅動(dong)(dong)(dong),轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)式機(ji)油(you)(you)(you)(you)(you)(you)泵(beng)(beng)(beng)的(de)(de)(de)(de)內(nei)(nei)、外(wai)(wai)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)是同向不(bu)同步(bu)的(de)(de)(de)(de)旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan),轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)齒(chi)(chi)(chi)(chi)(chi)(chi)形(xing)(xing)齒(chi)(chi)(chi)(chi)(chi)(chi)廓設計得使轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)到(dao)任何(he)角(jiao)度時(shi),內(nei)(nei)、外(wai)(wai)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)每個齒(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)(de)齒(chi)(chi)(chi)(chi)(chi)(chi)形(xing)(xing)廓線上(shang)(shang)(shang)總能互(hu)相成(cheng)點接觸。這樣(yang)內(nei)(nei)、外(wai)(wai)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)間形(xing)(xing)成(cheng)4個工作(zuo)腔(qiang)(qiang),隨著轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)的(de)(de)(de)(de)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)動(dong)(dong)(dong),這4個工作(zuo)腔(qiang)(qiang)的(de)(de)(de)(de)容(rong)(rong)積(ji)是不(bu)斷(duan)(duan)變化的(de)(de)(de)(de)。在(zai)進油(you)(you)(you)(you)(you)(you)道的(de)(de)(de)(de)一(yi)側(ce)空腔(qiang)(qiang),由(you)于(yu)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)脫開嚙合(he),容(rong)(rong)積(ji)逐漸增大,產生真空,機(ji)油(you)(you)(you)(you)(you)(you)被(bei)吸(xi)入,轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)繼續旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan),機(ji)油(you)(you)(you)(you)(you)(you)被(bei)帶到(dao)出(chu)(chu)(chu)油(you)(you)(you)(you)(you)(you)道的(de)(de)(de)(de)一(yi)側(ce),這時(shi),轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)正好進入嚙合(he),使這一(yi)空腔(qiang)(qiang)容(rong)(rong)積(ji)減(jian)小,油(you)(you)(you)(you)(you)(you)壓(ya)升高,機(ji)油(you)(you)(you)(you)(you)(you)從(cong)齒(chi)(chi)(chi)(chi)(chi)(chi)間擠出(chu)(chu)(chu)并經(jing)出(chu)(chu)(chu)油(you)(you)(you)(you)(you)(you)道壓(ya)送(song)出(chu)(chu)(chu)去。這樣(yang),隨著轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)的(de)(de)(de)(de)不(bu)斷(duan)(duan)旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan),機(ji)油(you)(you)(you)(you)(you)(you)就不(bu)斷(duan)(duan)地(di)被(bei)吸(xi)入和壓(ya)出(chu)(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。
