德國REXROTH柱塞 力士樂柱塞泵A10VSO28DRG現(xiàn)貨 德國REXROTH柱塞和柱塞套是一對精密偶件,，經(jīng)配對研磨后不能互換,，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,、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精密偶件,，配對研磨后不能互換,，其配合間隙為0.01mm。出油閥是一個單向閥,，在彈簧壓力作用下,，閥上部圓錐面與閥座嚴密配合，其作用是在停供時,，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斷面,，既能導向,，又能通過柴油。出油閥的錐面下有一個小的圓柱面,，稱為減壓環(huán)帶,，其作用是在供油終了時,，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,。當環(huán)帶落入閥座內(nèi)時則使上方容積很快增大,，壓力迅速減小，停噴迅速,。工作時,，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,、下往復運動,，從而完成泵油任務(wù)，泵油過程可分為以下三個階段,。
