style="text-indent:25px">柴油機(jī)共軌噴油系統(tǒng)有一個(gè)共同的特點(diǎn)，就是有一個(gè)共同的高壓燃油蓄勢(shì)器，稱為共軌。高壓供油泵只負(fù)責(zé)向這個(gè)蓄勢(shì)器提供高壓燃油，不負(fù)責(zé)控制燃油定量和噴油定時(shí)。治理燃油壓力和向各個(gè)氣缸輸送燃油的任務(wù)通過共軌完成。這樣，河南通用柱塞偶件銷售廠家，燃油噴射過程可以不受壓力產(chǎn)生和燃油輸送過程的牽制;燃油定量控制和噴油定時(shí)控制可以更為靈活和自由，河南通用柱塞偶件銷售廠家，河南通用柱塞偶件銷售廠家。相對(duì)于其他燃油噴射系統(tǒng)，共軌燃油噴射系統(tǒng)有如下特點(diǎn)：在燃油定量和噴油定時(shí)方面實(shí)行全電子的和柔性的控制;噴油規(guī)律曲線外形可以比較自由地調(diào)整;優(yōu)化的、已可達(dá)到1800bar的噴油壓力(僅次于博世公司的泵噴嘴和泵管嘴)控制;能實(shí)現(xiàn)每個(gè)工作循環(huán)多達(dá)七次的燃油噴射;高度的緊湊性和較低的高壓油泵驅(qū)動(dòng)扭矩。</p><div

style="text-indent:25px">噴油泵柱塞偶件的功用是提高柴油壓力，以滿足噴油嘴噴射壓力的要求，控制油量和供油時(shí)間。柱塞偶件是噴油泵總成中的重要部件，它不但要有良好的密封性，而且還要有良好的滑動(dòng)性。如果柱塞卡死或卡滯，將使齒條移動(dòng)困難，甚至不能移動(dòng)，且調(diào)整器失靈。這時(shí)會(huì)造成發(fā)動(dòng)機(jī)不能啟動(dòng)或工作“缺缸”，轉(zhuǎn)速不穩(wěn)(忽高忽低)，自行熄火或“飛車”等故障。柱塞式噴油泵的泵油是靠柱塞在柱塞套內(nèi)上下往復(fù)運(yùn)動(dòng)來完成的。柱塞套兩側(cè)有兩個(gè)起回油作用的小孔，與噴油泵體上的低壓油腔相通，柱塞偶件上方裝有出油閥偶件，用出油閥彈簧將出油閥壓在閥座上，與柱塞頂一起形成壓油空間。柱塞的下端靠柱塞彈簧緊壓在挺桿體總成上，挺桿體通過滾輪壓在(凸輪軸上的)凸輪上。當(dāng)凸輪頂起挺桿使柱塞上行，壓縮柴油迫使出油閥離開閥座，經(jīng)高壓油管壓入噴油嘴噴進(jìn)缸內(nèi);柱塞上升行程超過有效行程之后，柱塞上泄油針槽與柱塞套回油孔的下邊緣相通，供油便結(jié)束。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="河南通用柱塞偶件銷售廠家"

(1)檢查柱塞。若工作面有刻痕、腐蝕或柱塞彎曲、變形等現(xiàn)象，應(yīng)予以更換。 (2)滑動(dòng)試驗(yàn)。將柱塞徹底清洗干凈后，使其倒置并與水平面傾斜45°，先輕輕抽出柱塞約1/3，然后松開，柱塞應(yīng)能依靠自身重量沿套筒平穩(wěn)下滑，落到套筒支承面上。如此將柱塞轉(zhuǎn)動(dòng)幾個(gè)不同位置，反復(fù)試驗(yàn)幾次，每次都能符合上述要求，說明柱塞偶件配合良好。 (3)密封性試驗(yàn)。用手指堵住套筒上端孔和側(cè)面進(jìn)油孔，另一只手向外拉柱塞，手指應(yīng)感覺有吸力；放松柱塞時(shí)，柱塞應(yīng)能迅速回位。將柱塞轉(zhuǎn)動(dòng)幾個(gè)不同位置，反復(fù)試驗(yàn)幾次，均應(yīng)符合要求。</p></p><br /><p>文章來源地址:
