.減(jian)少(shao)(shao)沖擊(ji)和(he)振動(dong)。為了減(jian)少(shao)(shao)承(cheng)受沖擊(ji)和(he)振動(dong)的管(guan)接頭松動(dong)引起(qi)的泄漏,可以采(cai)取以下(xia)措施:
(1)使(shi)用(yong)減震支(zhi)架固定(ding)所有(you)管(guan)子(zi)以便吸收(shou)沖擊和振(zhen)動(dong);
(2)使用低沖(chong)擊(ji)(ji)閥(fa)或蓄能器(qi)來減(jian)少(shao)沖(chong)擊(ji)(ji);
(3)適當(dang)布置壓力控制閥來保護系統的所有元(yuan)件;
(4)盡量減少管(guan)接(jie)頭(tou)的使(shi)用(yong)數(shu)量,管(guan)接(jie)頭(tou)盡量用(yong)焊接(jie)連接(jie);
(5)使用直(zhi)螺(luo)紋接(jie)頭(tou),三通接(jie)頭(tou)和(he)彎頭(tou)代替(ti)錐管螺(luo)紋接(jie)頭(tou);
(6)盡量用回油(you)塊代替各個配管;
(7)針對使(shi)用的(de)(de)高壓力,規定安裝時使(shi)用螺栓(shuan)的(de)(de)扭矩和堵頭扭矩,防止(zhi)結合面和密封件被蠶食;
(8)正確安裝管接頭

液(ye)壓(ya)傳動中用來(lai)控(kong)(kong)制液(ye)體壓(ya)力、流(liu)量和方向的元(yuan)件。其中控(kong)(kong)制通、斷和流(liu)向的稱(cheng)為方向控(kong)(kong)制閥。
方向(xiang)控制閥(fa)按用途(tu)分為單向(xiang)閥(fa)和換向(xiang)閥(fa)。
1、單向閥：只允許(xu)流體(ti)在管道中單向接通，反向即切斷。
2、換向閥(fa)(fa)：改變不同管路間的(de)通(tong)(tong)(tong)(tong)、斷關系、根(gen)(gen)(gen)據(ju)閥(fa)(fa)芯(xin)在(zai)閥(fa)(fa)體中(zhong)的(de)工作位(wei)(wei)置數分兩位(wei)(wei)、三位(wei)(wei)等；根(gen)(gen)(gen)據(ju)所控制的(de)通(tong)(tong)(tong)(tong)道(dao)數分兩通(tong)(tong)(tong)(tong)、三通(tong)(tong)(tong)(tong)、四通(tong)(tong)(tong)(tong)、五(wu)通(tong)(tong)(tong)(tong)等；如(ru)二(er)位(wei)(wei)二(er)通(tong)(tong)(tong)(tong)、三位(wei)(wei)三通(tong)(tong)(tong)(tong)，三位(wei)(wei)五(wu)通(tong)(tong)(tong)(tong)等根(gen)(gen)(gen)據(ju)閥(fa)(fa)芯(xin)驅動(dong)方式分手動(dong)、機動(dong)、電磁、液動(dong)等。
60年代后期(qi)，在(zai)上述幾種液(ye)(ye)(ye)壓(ya)控(kong)制(zhi)(zhi)閥(fa)(fa)的(de)基礎上又研(yan)制(zhi)(zhi)出電(dian)液(ye)(ye)(ye)比例(li)(li)(li)控(kong)制(zhi)(zhi)閥(fa)(fa)。它(ta)的(de)輸出量(liang)(壓(ya)力、流量(liang))能隨輸入的(de)電(dian)信號(hao)連續變化。電(dian)液(ye)(ye)(ye)比例(li)(li)(li)控(kong)制(zhi)(zhi)閥(fa)(fa)按作用不同，相應地分為電(dian)液(ye)(ye)(ye)比例(li)(li)(li)壓(ya)力控(kong)制(zhi)(zhi)閥(fa)(fa)、電(dian)液(ye)(ye)(ye)比例(li)(li)(li)流量(liang)控(kong)制(zhi)(zhi)閥(fa)(fa)和電(dian)液(ye)(ye)(ye)比例(li)(li)(li)方向控(kong)制(zhi)(zhi)閥(fa)(fa)等。

液(ye)(ye)壓(ya)(ya)(ya)閥(fa)(fa)在(zai)液(ye)(ye)壓(ya)(ya)(ya)系(xi)(xi)統中(zhong)(zhong)(zhong)的(de)(de)(de)(de)工(gong)(gong)作(zuo)(zuo)(zuo)方式是(shi)閥(fa)(fa)體和閥(fa)(fa)芯(xin)(xin)相對運動，這種工(gong)(gong)作(zuo)(zuo)(zuo)方式不(bu)可避(bi)免的(de)(de)(de)(de)就是(shi)磨(mo)損。液(ye)(ye)壓(ya)(ya)(ya)閥(fa)(fa)的(de)(de)(de)(de)閥(fa)(fa)體和閥(fa)(fa)芯(xin)(xin)進行(xing)相對運動的(de)(de)(de)(de)過程中(zhong)(zhong)(zhong)，會不(bu)斷的(de)(de)(de)(de)摩(mo)(mo)擦，在(zai)工(gong)(gong)作(zuo)(zuo)(zuo)一(yi)段時間后，液(ye)(ye)壓(ya)(ya)(ya)閥(fa)(fa)各元件(jian)之間的(de)(de)(de)(de)尺寸(cun)、形狀、質(zhi)量等發(fa)生變(bian)化，不(bu)再(zai)是(shi)液(ye)(ye)壓(ya)(ya)(ya)閥(fa)(fa)原有的(de)(de)(de)(de)特性，在(zai)液(ye)(ye)壓(ya)(ya)(ya)閥(fa)(fa)工(gong)(gong)作(zuo)(zuo)(zuo)中(zhong)(zhong)(zhong)就會失效，出現故(gu)障(zhang)。例如，在(zai)液(ye)(ye)壓(ya)(ya)(ya)系(xi)(xi)統中(zhong)(zhong)(zhong)的(de)(de)(de)(de)減(jian)(jian)壓(ya)(ya)(ya)閥(fa)(fa)工(gong)(gong)作(zuo)(zuo)(zuo)中(zhong)(zhong)(zhong)，錐閥(fa)(fa)和閥(fa)(fa)座之間因為長時間的(de)(de)(de)(de)摩(mo)(mo)擦、磨(mo)損，造成零(ling)件(jian)之間的(de)(de)(de)(de)配(pei)合度不(bu)好，在(zai)液(ye)(ye)壓(ya)(ya)(ya)系(xi)(xi)統中(zhong)(zhong)(zhong)，減(jian)(jian)壓(ya)(ya)(ya)閥(fa)(fa)就無法起(qi)到(dao)減(jian)(jian)壓(ya)(ya)(ya)的(de)(de)(de)(de)作(zuo)(zuo)(zuo)用。
