哈威HAWE柱塞泵&&德國(guó)哈威HAWE泵,hawe柱塞泵
哈威柱塞泵的泵油機(jī)構(gòu)包括兩套精密偶件:柱塞(plunger)+柱塞套(barrel)構(gòu)成柱塞偶件(plunger and barrel assembly)(圖5-11)、出油閥(delivery valve)和出油閥座(delivery valve seat)構(gòu)成出油閥偶件(delivery valve assembly
柱塞和柱塞套是一對(duì)精密偶件,,經(jīng)配對(duì)研磨后不能互換,,要求有高的精度和光潔度和好的耐磨性,其徑向間隙為0.002~0.003mm
HAWE 柱塞頭部圓柱面上切有斜槽,,并通過徑向孔,、軸向孔與頂部相通,其目的是改變循環(huán)供油量,;柱塞套上制有進(jìn),、回油孔,均與泵上體內(nèi)低壓油腔相通,,柱塞套裝入泵上體后,,應(yīng)用定位螺釘定位。
柱塞頭部斜槽的位置不同,,改變供油量的方法也不同,。
出油閥和出油閥座也是一對(duì)精密偶件,配對(duì)研磨后不能互換,,其配合間隙為0.01mm ,。
出油閥是一個(gè)單向閥,在彈簧壓力作用下,,閥上部圓錐面與閥座嚴(yán)密配合,,其作用是在停供時(shí),,將高壓油管與柱塞上端空腔隔絕,防止高壓油管內(nèi)的油倒流入噴油泵內(nèi),。
出油閥的下部呈十字?jǐn)嗝?,既能?dǎo)向,又能通過柴油,。出油閥的錐面下有一個(gè)小的圓柱面,,稱為減壓環(huán)帶,其作用是在供油終了時(shí),,使高壓油管內(nèi)的油壓迅速下降,,避免噴孔處產(chǎn)生滴油現(xiàn)象。當(dāng)環(huán)帶落入閥座內(nèi)時(shí)則使上方容積很快增大,,壓力迅速減小,,停噴迅速。
工作時(shí),,在噴油泵凸輪軸上的凸輪與柱塞彈簧的作用下,,迫使柱塞作上、下往復(fù)運(yùn)動(dòng),,從而完成泵油任務(wù),,泵油過程可分為以下三個(gè)階段。: :王
