壓機油泵

壓機(ji)(ji)油(you)泵由主機(ji)(ji)和(he)控制(zhi)(zhi)機(ji)(ji)構(gou)兩部分組成。液壓機(ji)(ji)的(de)主體(ti)包括機(ji)(ji)身、主油(you)缸、頂出油(you)缸和(he)充液裝(zhuang)(zhuang)置(zhi)。動力(li)機(ji)(ji)構(gou)由油(you)箱、高壓泵、低(di)壓控制(zhi)(zhi)系(xi)統、電機(ji)(ji)、各(ge)(ge)種(zhong)壓力(li)閥和(he)定向(xiang)閥組成。動力(li)機(ji)(ji)構(gou)在電氣裝(zhuang)(zhuang)置(zhi)的(de)控制(zhi)(zhi)下，通(tong)過泵、缸及各(ge)(ge)種(zhong)液壓閥實現能量轉(zhuan)換、調節和(he)傳遞，完成各(ge)(ge)種(zhong)工藝動作的(de)循環。

壓(ya)(ya)(ya)(ya)機(ji)(ji)油(you)(you)泵(beng)(beng)(beng)可以(yi)分為(wei)：軸向柱(zhu)(zhu)(zhu)塞(sai)泵(beng)(beng)(beng)是利用(yong)活(huo)(huo)塞(sai)在活(huo)(huo)塞(sai)孔中平(ping)行(xing)于(yu)驅動(dong)軸的往復(fu)運動(dong)所(suo)產(chan)生的體積變(bian)化來操作的。由(you)于(yu)柱(zhu)(zhu)(zhu)塞(sai)和柱(zhu)(zhu)(zhu)塞(sai)孔是圓形(xing)零件，加工時能達到高精度，所(suo)以(yi)體積效率高、運轉平(ping)穩、流量均勻性好、噪(zao)音低、工作壓(ya)(ya)(ya)(ya)力高等優點，但液壓(ya)(ya)(ya)(ya)油(you)(you)污染(ran)比(bi)較敏感、比(bi)較復(fu)雜。架(jia)構，成(cheng)本更高。直軸斜盤(pan)(pan)柱(zhu)(zhu)(zhu)塞(sai)泵(beng)(beng)(beng)直軸斜盤(pan)(pan)柱(zhu)(zhu)(zhu)塞(sai)泵(beng)(beng)(beng)可分為(wei)兩種類(lei)型：壓(ya)(ya)(ya)(ya)力供(gong)油(you)(you)型自(zi)吸油(you)(you)型。壓(ya)(ya)(ya)(ya)力供(gong)油(you)(you)型液壓(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)大多采用(yong)氣動(dong)油(you)(you)箱(xiang)，還(huan)有(you)帶有(you)充油(you)(you)泵(beng)(beng)(beng)的液壓(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)向液壓(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)的進口提(ti)供(gong)壓(ya)(ya)(ya)(ya)力油(you)(you)。廣泛用(yong)于(yu)汽車零部件加工及各種工業(ye)產(chan)品的定型、沖壓(ya)(ya)(ya)(ya)、校準和制鞋(xie)、手袋、橡(xiang)膠、模具(ju)、軸、套筒、沖壓(ya)(ya)(ya)(ya)成(cheng)型、板件彎曲(qu)、沖壓(ya)(ya)(ya)(ya)、套筒拉伸等工藝，洗衣機(ji)(ji)、電機(ji)(ji)、汽車。汽車電機(ji)(ji)、空(kong)調電機(ji)(ji)、微電機(ji)(ji)、伺服電機(ji)(ji)、車輪制造、減震器、摩(mo)托車及機(ji)(ji)械行(xing)業(ye)。
