三、高壓膠管有多少種
高壓(ya)膠管(guan)(guan)按照(zhao)制作工藝主要分為高壓(ya)鋼絲纏繞(rao)膠管(guan)(guan)與高壓(ya)鋼絲編(bian)織膠管(guan)(guan)兩種(zhong):
1、高壓鋼絲纏繞膠管
高壓(ya)(ya)鋼(gang)絲(si)纏繞膠(jiao)管結構主要(yao)由內膠(jiao)層(ceng)(ceng)(ceng)(ceng)、中膠(jiao)層(ceng)(ceng)(ceng)(ceng)、四(si)層(ceng)(ceng)(ceng)(ceng)或多(duo)層(ceng)(ceng)(ceng)(ceng)交替纏繞的鋼(gang)絲(si)增強(qiang)層(ceng)(ceng)(ceng)(ceng)和外膠(jiao)層(ceng)(ceng)(ceng)(ceng)組成,內膠(jiao)層(ceng)(ceng)(ceng)(ceng)具有使輸送介(jie)質承受壓(ya)(ya)力,保護鋼(gang)絲(si)不受侵蝕的作用,外膠(jiao)層(ceng)(ceng)(ceng)(ceng)保護鋼(gang)絲(si)不受損傷,鋼(gang)絲(si)(ф0.3-2.0增強(qiang)層(ceng)(ceng)(ceng)(ceng))層(ceng)(ceng)(ceng)(ceng)是骨架材料起增強(qiang)作用。高壓(ya)(ya)鋼(gang)絲(si)纏繞膠(jiao)管管工(gong)作溫度(du):-40℃~120℃,產品(pin)規格(ge)范(fan)圍:DN6mm~DN305mm。
2、高壓鋼絲編織膠管
高壓鋼(gang)(gang)絲(si)編(bian)(bian)織(zhi)膠(jiao)(jiao)管(guan)(guan)結(jie)構主要由耐液(ye)體的(de)(de)合成橡膠(jiao)(jiao)內膠(jiao)(jiao)層(ceng)(ceng)(ceng)、中膠(jiao)(jiao)層(ceng)(ceng)(ceng)、Ⅰ、Ⅱ、Ⅲ層(ceng)(ceng)(ceng)鋼(gang)(gang)絲(si)編(bian)(bian)織(zhi)層(ceng)(ceng)(ceng)、耐天候(hou)的(de)(de)合成橡膠(jiao)(jiao)外膠(jiao)(jiao)層(ceng)(ceng)(ceng)組成。高壓鋼(gang)(gang)絲(si)編(bian)(bian)織(zhi)膠(jiao)(jiao)管(guan)(guan)工作溫度:油類-40℃~100℃,空(kong)氣-30℃~50℃,水乳液(ye)+80℃以下。高壓鋼(gang)(gang)絲(si)編(bian)(bian)織(zhi)膠(jiao)(jiao)管(guan)(guan)規(gui)格(ge)范(fan)圍:DN5mm~DN102mm。
四、高壓膠管有什么要求
除了安全可(ke)靠的產(chan)品質(zhi)量,根據使用需求(qiu)選擇合適的高壓膠(jiao)管也是很重要的,一(yi)般使用的高壓膠(jiao)管要求(qiu)做到(dao):
1、根(gen)據系(xi)統的(de)(de)壓(ya)(ya)(ya)(ya)力(li),選擇膠(jiao)(jiao)管(guan)(guan)的(de)(de)鋼絲(si)層(ceng)數,壓(ya)(ya)(ya)(ya)力(li)高,鋼絲(si)的(de)(de)層(ceng)數多。每種膠(jiao)(jiao)管(guan)(guan)都有一個(ge)大的(de)(de)工(gong)(gong)作(zuo)壓(ya)(ya)(ya)(ya)力(li),膠(jiao)(jiao)管(guan)(guan)的(de)(de)爆破壓(ya)(ya)(ya)(ya)力(li)為大工(gong)(gong)作(zuo)壓(ya)(ya)(ya)(ya)力(li)的(de)(de)4倍(bei)。所以根(gen)據實際的(de)(de)系(xi)統壓(ya)(ya)(ya)(ya)力(li),選擇的(de)(de)膠(jiao)(jiao)管(guan)(guan)的(de)(de)大工(gong)(gong)作(zuo)壓(ya)(ya)(ya)(ya)力(li)比實際工(gong)(gong)作(zuo)壓(ya)(ya)(ya)(ya)力(li)大點(dian)即(ji)可。
2、根據流量選擇膠管的(de)(de)內(nei)徑,管(guan)(guan)徑過(guo)(guo)小會加大(da)管(guan)(guan)內(nei)介質的(de)(de)流速,使系統(tong)發熱,降低效率(lv),而(er)且會產生過(guo)(guo)大(da)的(de)(de)壓降,影響整個(ge)系統(tong)的(de)(de)性能,管(guan)(guan)徑過(guo)(guo)大(da)會增加成(cheng)本,所以膠管(guan)(guan)內(nei)徑要適(shi)當(dang)。當(dang)膠管(guan)(guan)用管(guan)(guan)夾固定或膠管(guan)(guan)穿過(guo)(guo)鋼板(ban)等間隔(ge)物時,也要注(zhu)意膠管(guan)(guan)的(de)(de)外徑尺寸(cun)。
3、在選擇高壓(ya)膠(jiao)管(guan)(guan)時應該(gai)注意(yi)高壓(ya)膠(jiao)管(guan)(guan)的彎曲半徑(jing),計(ji)算彎曲半徑(jing)時應該(gai)減去前(qian)面接頭的扣(kou)壓(ya)長度(du)。若安(an)裝的膠(jiao)管(guan)(guan)彎曲半徑(jing)過(guo)小(xiao),將降低膠(jiao)管(guan)(guan)的承壓(ya)能(neng)力并影響其(qi)壽命。
