　　● 用途

　　KCB型齒(chi)輪泵適(shi)用于(yu)輸送不含固體顆(ke)粒和纖維，無(wu)腐蝕性，溫度不高(gao)于(yu)80℃，粘度為5×10-6～1.5×10-3m2/s (5-1500cSt)的潤滑油(you)或性質類似潤滑油(you)的其他(ta)液體。

　　● 結構 性

　　本系列齒輪(lun)泵(beng)(beng)(beng)主要有齒輪(lun)、軸、泵(beng)(beng)(beng)體、閥、軸端密封所組(zu)成。齒輪(lun)經熱(re)處(chu)理(li)有較高(gao)的(de)硬度和強度，與軸一同安(an)裝在(zai)(zai)可(ke) 換(huan)的(de)軸套內運轉。泵(beng)(beng)(beng)內全(quan)部零件的(de)潤滑均在(zai)(zai)泵(beng)(beng)(beng)工作時(shi)利用輸(shu)出介質(zhi)而自動達到(dao)。 泵(beng)(beng)(beng)內有設計合理(li)的(de)泄油和回油槽，是齒輪(lun)在(zai)(zai)工作中(zhong)承受的(de)扭矩力小，因此(ci)軸承負荷小，磨損小，泵(beng)(beng)(beng)效率高(gao)。

　　泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)設有(you)閥作(zuo)為超(chao)載保護(hu)，閥的(de)全(quan)回(hui)流壓(ya)(ya)(ya)力(li)為泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)額定排(pai)(pai)除(chu)壓(ya)(ya)(ya)力(li)的(de)1.5倍(bei)，也可在允許排(pai)(pai)出(chu)壓(ya)(ya)(ya)力(li)范(fan)圍(wei)(wei)內根(gen)據實(shi)際需(xu)要另(ling)外(wai)調整。但注意本閥不(bu)能(neng)作(zuo)減壓(ya)(ya)(ya)閥的(de)長期工(gong)作(zuo)，需(xu)要時(shi)(shi)可在管路上另(ling)行安裝。從主軸外(wai)伸(shen)端向泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)看，為順時(shi)(shi)針旋轉(zhuan)。各型齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)的(de)性(xing)能(neng)參數(shu)，是(shi)(shi)在介質粘度(du)4×10-3m2/s(40cSt)時(shi)(shi)確(que)(que)定的(de)。性(xing)能(neng)參數(shu)表中(zhong)給(gei)出(chu)的(de)參數(shu)值(zhi)適用(yong)(yong)于介質粘度(du)1×10-5～8×10-5m2/s(10～80cSt)范(fan)圍(wei)(wei)內，超(chao)出(chu)這個(ge)范(fan)圍(wei)(wei)則根(gen)據用(yong)(yong)戶提出(chu)的(de)性(xing)能(neng)參數(shu)要求(qiu)另(ling)行確(que)(que)定。 各型齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)性(xing)能(neng)參數(shu)中(zhong)給(gei)出(chu)的(de)排(pai)(pai)出(chu)壓(ya)(ya)(ya)力(li)是(shi)(shi)給(gei)出(chu)的(de)大的(de)工(gong)作(zuo)壓(ya)(ya)(ya)力(li)值(zhi)，在此范(fan)圍(wei)(wei)內泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)均(jun)能(neng)正常工(gong)作(zuo)，其工(gong)作(zuo)范(fan)圍(wei)(wei)見圖一。KCB系(xi)列齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)油(you)(you)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)是(shi)(shi)有(you)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)體、前后泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)蓋、齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)、主被動(dong)(dong)(dong)軸、軸承、閥和軸端密封(feng)等零件組成。KCB18.3——83.3主傳動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)是(shi)(shi)一對斜(xie)(xie)齒(chi)(chi)(chi)(chi)(chi)(chi)園(yuan)柱(zhu)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)，直動(dong)(dong)(dong)式閥。KCB200—960主傳動(dong)(dong)(dong)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)是(shi)(shi)四個(ge)斜(xie)(xie)齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)組成的(de)人字形齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)組，差壓(ya)(ya)(ya)式閥。全(quan)系(xi)列齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)油(you)(you)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)用(yong)(yong)三爪式彈性(xing)聯軸器與電(dian)動(dong)(dong)(dong)機組成的(de)熱油(you)(you)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)機組。 本系(xi)列齒(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)油(you)(you)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)結構簡單緊湊，使(shi)用(yong)(yong)維護(hu)方便(bian)，運轉(zhuan)平穩，使(shi)用(yong)(yong) 。
