YHG1型冶(ye)金設備標(biao)準液壓缸
Y-HG1型冶金設備(bei)標(biao)準液(ye)壓(ya)(ya)缸(gang)(gang)，為(wei)雙(shuang)作用(yong)(yong)單活塞(sai)桿液(ye)壓(ya)(ya)缸(gang)(gang)，缸(gang)(gang)徑(jing)從40~320mm共有(you)17種(zhong)規格，額定(ding)壓(ya)(ya)力為(wei)16MPa，可(ke)以帶緩沖裝(zhuang)置。該系列液(ye)壓(ya)(ya)缸(gang)(gang)有(you)13種(zhong)安裝(zhuang)連(lian)接型式，除軸向腳架式外，安裝(zhuang)連(lian)裝(zhuang)尺寸均符合(he)ISO6021/1-1981的(de)規定(ding)。活塞(sai)桿端螺紋亦符合(he)GB2350-80的(de)規定(ding)。適用(yong)(yong)于(yu)工作溫度為(wei)-30C~+80C，工作介(jie)質為(wei)液(ye)壓(ya)(ya)油，乳化液(ye)的(de)冶金設備(bei)（不適用(yong)(yong)于(yu)磷酸脂(zhi)）。
液壓缸(gang)(gang)結構(gou)基本(ben)上可以(yi)分(fen)為缸(gang)(gang)筒(tong)和缸(gang)(gang)蓋、活(huo)塞和活(huo)塞桿、密封裝置、緩(huan)沖(chong)裝置和排氣裝置五個部分(fen)。今天威海(hai)力建(jian)小編著重(zhong)帶(dai)著大家了解一下缸(gang)(gang)筒(tong)和缸(gang)(gang)蓋。
缸筒和缸蓋
一(yi)般來說，缸(gang)(gang)筒(tong)(tong)和(he)缸(gang)(gang)蓋的結(jie)構(gou)形(xing)(xing)式(shi)(shi)和(he)其使(shi)用(yong)(yong)(yong)的材料有(you)關。工(gong)(gong)作(zuo)壓力p＜10MPa時，使(shi)用(yong)(yong)(yong)鑄鐵(tie)；p＜20MPa時，使(shi)用(yong)(yong)(yong)無縫(feng)鋼(gang)管(guan)(guan)；p＞20MPa時，使(shi)用(yong)(yong)(yong)鑄鋼(gang)或(huo)鍛鋼(gang)。法蘭(lan)連(lian)(lian)接(jie)(jie)(jie)(jie)式(shi)(shi)，結(jie)構(gou)簡單，容(rong)易(yi)加(jia)(jia)工(gong)(gong)，也容(rong)易(yi)裝拆(chai)(chai)，但外(wai)(wai)形(xing)(xing)尺寸(cun)(cun)和(he)重量(liang)(liang)都較(jiao)(jiao)(jiao)大(da)，常(chang)用(yong)(yong)(yong)于鑄鐵(tie)制的缸(gang)(gang)筒(tong)(tong)上。半環連(lian)(lian)接(jie)(jie)(jie)(jie)式(shi)(shi)，它(ta)的缸(gang)(gang)筒(tong)(tong)壁部因開了環形(xing)(xing)槽(cao)而削弱了強度(du)，為此有(you)時要加(jia)(jia)厚缸(gang)(gang)壁，它(ta)容(rong)易(yi)加(jia)(jia)工(gong)(gong)和(he)裝拆(chai)(chai)，重量(liang)(liang)較(jiao)(jiao)(jiao)輕，常(chang)用(yong)(yong)(yong)于無縫(feng)鋼(gang)管(guan)(guan)或(huo)鍛鋼(gang)制的缸(gang)(gang)筒(tong)(tong)上。螺紋連(lian)(lian)接(jie)(jie)(jie)(jie)式(shi)(shi)，它(ta)的缸(gang)(gang)筒(tong)(tong)端部結(jie)構(gou)復雜，外(wai)(wai)徑加(jia)(jia)工(gong)(gong)時要求保證(zheng)內外(wai)(wai)徑同心，裝拆(chai)(chai)要使(shi)用(yong)(yong)(yong)工(gong)(gong)具，它(ta)的外(wai)(wai)形(xing)(xing)尺寸(cun)(cun)和(he)重量(liang)(liang)都較(jiao)(jiao)(jiao)小(xiao)，常(chang)用(yong)(yong)(yong)于無縫(feng)鋼(gang)管(guan)(guan)或(huo)鑄鋼(gang)制的缸(gang)(gang)筒(tong)(tong)上。拉桿連(lian)(lian)接(jie)(jie)(jie)(jie)式(shi)(shi)，結(jie)構(gou)的通(tong)用(yong)(yong)(yong)性(xing)大(da)，容(rong)易(yi)加(jia)(jia)工(gong)(gong)和(he)裝拆(chai)(chai)，但外(wai)(wai)形(xing)(xing)尺寸(cun)(cun)較(jiao)(jiao)(jiao)大(da)，且(qie)較(jiao)(jiao)(jiao)重。焊接(jie)(jie)(jie)(jie)連(lian)(lian)接(jie)(jie)(jie)(jie)式(shi)(shi)，結(jie)構(gou)簡單，尺寸(cun)(cun)小(xiao)，但缸(gang)(gang)底處內徑不易(yi)加(jia)(jia)工(gong)(gong)，且(qie)可能引起變形(xing)(xing)。
零(ling)部(bu)件加(jia)(jia)(jia)工(gong)(gong)(gong)精(jing)(jing)度(du)(du)(du)的(de)(de)影響(xiang)問題，在(zai)液壓(ya)缸的(de)(de)制造過程中應嚴格(ge)控制缸體內(nei)壁和(he)活塞(sai)桿表(biao)面(mian)加(jia)(jia)(jia)工(gong)(gong)(gong)精(jing)(jing)度(du)(du)(du)，特別是幾何(he)精(jing)(jing)度(du)(du)(du)，尤(you)其直(zhi)(zhi)線(xian)度(du)(du)(du)是關鍵，在(zai)國內(nei)加(jia)(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)(yi)中，活塞(sai)桿表(biao)面(mian)的(de)(de)加(jia)(jia)(jia)工(gong)(gong)(gong)基本(ben)上是車(che)后磨(mo)削，保證直(zhi)(zhi)線(xian)度(du)(du)(du)問題不(bu)大(da)，但(dan)對于(yu)缸體內(nei)壁的(de)(de)加(jia)(jia)(jia)工(gong)(gong)(gong)，其加(jia)(jia)(jia)工(gong)(gong)(gong)方(fang)法很多(duo)，有鏜(tang)削-滾壓(ya)、鏜(tang)削-珩(heng)磨(mo)、直(zhi)(zhi)接(jie)珩(heng)磨(mo)等，但(dan)由于(yu)國內(nei)材料的(de)(de)基礎水平(ping)較國外有差(cha)距，管材坯料直(zhi)(zhi)線(xian)度(du)(du)(du)差(cha)，壁厚不(bu)均(jun)勻、硬度(du)(du)(du)不(bu)均(jun)勻等因素，往(wang)往(wang)直(zhi)(zhi)接(jie)影響(xiang)缸體內(nei)壁加(jia)(jia)(jia)工(gong)(gong)(gong)后的(de)(de)直(zhi)(zhi)線(xian)度(du)(du)(du)，因此建(jian)議(yi)采(cai)用鏜(tang)削-滾壓(ya)、鏜(tang)削-珩(heng)磨(mo)工(gong)(gong)(gong)藝(yi)(yi)，如直(zhi)(zhi)接(jie)珩(heng)磨(mo)，則(ze)必(bi)須首先提高管材坯料的(de)(de)直(zhi)(zhi)線(xian)度(du)(du)(du)。

在(zai)允(yun)許(xu)的(de)(de)情(qing)況下(xia)(xia)，液(ye)壓缸(gang)(gang)的(de)(de)缸(gang)(gang)體壁(bi)厚安全系(xi)數盡量選大一些，使(shi)(shi)缸(gang)(gang)體厚壁(bi)增加，特別是高壓工況下(xia)(xia)使(shi)(shi)用的(de)(de)油(you)缸(gang)(gang)，以減(jian)小油(you)壓下(xia)(xia)的(de)(de)缸(gang)(gang)體變(bian)形，變(bian)形后的(de)(de)缸(gang)(gang)體也會(hui)引起液(ye)壓缸(gang)(gang)低速爬行。
