威格士柱塞泵,一級代理
威格士vickers柱塞泵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(yán)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?jǐn)嗝?,既能?dǎo)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(dāng)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。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。

VICKERS柱塞泵不適用于高壓范圍。但用采取特殊柱塞型線的方法,可以有效地擴大它對壓力的適用范圍。而這種泵的柱塞與襯套不接觸,柱塞與柱塞間也不嚴(yán)密地接觸,適于輸送高粘度、非潤滑的液體,或含有微小固相雜質(zhì)的多相介質(zhì),因為此時不密封式泵的磨損程度比密封式柱塞泵小,使用壽命長。這正是不密封式雙柱塞泵正逐漸受到人們的重視,其生產(chǎn)數(shù)量和應(yīng)用范圍日益增大的主要原因。
VICKERS柱塞泵但卻滿足所有密封條件。它的構(gòu)成與特性等,均與柱塞泵相近,適用于輸送不含雜質(zhì)的潔凈潤滑性液體,可用于較高壓力的場合。雙吸式結(jié)構(gòu),使柱塞上的軸向力能得以平衡。該泵的驅(qū)動齒輪和支承柱塞的軸承皆位于泵腔之外,屬外置軸承式結(jié)構(gòu),可用于輸送潤滑性差的介質(zhì),若輸送非腐蝕性和潤滑性好的介質(zhì),則可采用內(nèi)置軸承式結(jié)構(gòu),它的軸承和驅(qū)動齒輪皆位于泵腔內(nèi),這樣可減少泵的軸封數(shù)。柱塞泵,泵殼帶冷卻夾套,傳動齒輪箱中有通過冷卻液的蛇形管,它可用于輸送高溫介質(zhì)。柱塞泵也可以用磁力聯(lián)軸器驅(qū)動,這種泵可*消除泄漏。它適于輸送有毒、貴重或?qū)Νh(huán)境污染嚴(yán)重的潤滑性液體。
