液(ye)壓缸(gang)(gang)結(jie)構基本上(shang)可以分(fen)為缸(gang)(gang)筒(tong)(tong)和(he)(he)缸(gang)(gang)蓋(gai)、活(huo)塞和(he)(he)活(huo)塞桿、密封裝(zhuang)置、緩沖裝(zhuang)置和(he)(he)排氣裝(zhuang)置五(wu)個部分(fen)。今天威(wei)海力建(jian)小編著重(zhong)帶著大家了解(jie)一下缸(gang)(gang)筒(tong)(tong)和(he)(he)缸(gang)(gang)蓋(gai)。

 缸(gang)筒(tong)和缸(gang)蓋

一(yi)般來說，缸(gang)筒(tong)(tong)和(he)(he)(he)(he)缸(gang)蓋的(de)結構(gou)(gou)形(xing)(xing)式(shi)和(he)(he)(he)(he)其(qi)使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)的(de)材料(liao)有關(guan)。工(gong)(gong)作壓力p＜10MPa時(shi)，使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)鑄(zhu)鐵(tie)；p＜20MPa時(shi)，使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)無縫鋼(gang)(gang)(gang)管；p＞20MPa時(shi)，使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)鑄(zhu)鋼(gang)(gang)(gang)或(huo)鍛(duan)(duan)鋼(gang)(gang)(gang)。法蘭連接(jie)(jie)式(shi)，結構(gou)(gou)簡(jian)單(dan)，容易加(jia)(jia)工(gong)(gong)，也容易裝(zhuang)拆(chai)，但(dan)外(wai)形(xing)(xing)尺寸(cun)(cun)和(he)(he)(he)(he)重量都較(jiao)大(da)，常用(yong)(yong)(yong)(yong)(yong)于鑄(zhu)鐵(tie)制(zhi)的(de)缸(gang)筒(tong)(tong)上(shang)。半(ban)環連接(jie)(jie)式(shi)，它(ta)的(de)缸(gang)筒(tong)(tong)壁部因開了環形(xing)(xing)槽而削弱了強度(du)，為此(ci)有時(shi)要(yao)加(jia)(jia)厚缸(gang)壁，它(ta)容易加(jia)(jia)工(gong)(gong)和(he)(he)(he)(he)裝(zhuang)拆(chai)，重量較(jiao)輕(qing)，常用(yong)(yong)(yong)(yong)(yong)于無縫鋼(gang)(gang)(gang)管或(huo)鍛(duan)(duan)鋼(gang)(gang)(gang)制(zhi)的(de)缸(gang)筒(tong)(tong)上(shang)。螺紋連接(jie)(jie)式(shi)，它(ta)的(de)缸(gang)筒(tong)(tong)端部結構(gou)(gou)復雜，外(wai)徑加(jia)(jia)工(gong)(gong)時(shi)要(yao)求保(bao)證內外(wai)徑同心，裝(zhuang)拆(chai)要(yao)使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)工(gong)(gong)具(ju)，它(ta)的(de)外(wai)形(xing)(xing)尺寸(cun)(cun)和(he)(he)(he)(he)重量都較(jiao)小(xiao)，常用(yong)(yong)(yong)(yong)(yong)于無縫鋼(gang)(gang)(gang)管或(huo)鑄(zhu)鋼(gang)(gang)(gang)制(zhi)的(de)缸(gang)筒(tong)(tong)上(shang)。拉桿(gan)連接(jie)(jie)式(shi)，結構(gou)(gou)的(de)通用(yong)(yong)(yong)(yong)(yong)性大(da)，容易加(jia)(jia)工(gong)(gong)和(he)(he)(he)(he)裝(zhuang)拆(chai)，但(dan)外(wai)形(xing)(xing)尺寸(cun)(cun)較(jiao)大(da)，且較(jiao)重。焊接(jie)(jie)連接(jie)(jie)式(shi)，結構(gou)(gou)簡(jian)單(dan)，尺寸(cun)(cun)小(xiao)，但(dan)缸(gang)底處內徑不易加(jia)(jia)工(gong)(gong)，且可能(neng)引起(qi)變(bian)形(xing)(xing)。

現象（一）：唇口破(po)損

原因：

1.背壓損傷

防止措施：

1.在(zai)活塞(sai)頭(tou)靠經唇口側加開泄壓孔(kong)或(huo)者改用組合類雙作用密(mi)封

現象（二）：焦燒(shao)

原因：

1.系(xi)統(tong)內有殘留(liu)空氣在運行時，空氣在密封處聚集壓縮升溫產(chan)生密封焦燒碳化

防止措施：

1.在油缸(gang)起動(dong)之前，盡量(liang)排盡油缸(gang)內空氣(qi)

2.油缸起動時，不要立即(ji)開到高(gao)速

3.當用U形圈時(shi)在其谷部加入潤滑脂，以(yi)防空(kong)氣積累

原因：

1.溫度太高

2.介(jie)質與(yu)橡膠材料不相適(shi)應

3.介質變質

4.密封受潮或者在空氣中暴露時間過(guo)長超過(guo)庫(ku)存期限導致材料老(lao)化

防止措施：

1.降低(di)溫度(du)，或者更(geng)換耐高溫密封(feng)件材料(liao)

2.更改介(jie)質或更改耐介(jie)質的密封件材料

3.換新介質

4.不(bu)要將密封件長(chang)時間暴露在大氣(qi)中(zhong)，嚴格按照密封庫存要求對密封進行保(bao)存
