眾所(suo)周知，支護設備中應用(yong)廣泛(fan)的(de)該是單體(ti)液(ye)壓支柱。而(er)根據(ju)單體(ti)液(ye)壓支柱規格不同，整柱重(zhong)量比國內外現用(yong)支柱減輕15-30%以(yi)上(shang)，但(dan)其工(gong)作阻力、工(gong)作行程(cheng)及穩定(ding)性安(an)全(quan)系(xi)數(shu)又高于鋁合金支柱。工(gong)作行程(cheng)大(da)，使用(yong)范圍廣。以(yi)上(shang)介(jie)紹的(de)便是我們(men)接下來所(suo)要講解的(de)DW單體(ti)液(ye)壓支柱。

應用如此(ci)廣泛的DW單(dan)體液壓支(zhi)柱(zhu)是不(bu)(bu)是有什么不(bu)(bu)可告人的秘密，要不(bu)(bu)然怎會(hui)如此(ci)受歡(huan)迎呢，接下來小編便帶(dai)領大家(jia)對(dui)DW單(dan)體液壓支(zhi)柱(zhu)進行(xing)揭秘呦，千萬(wan)不(bu)(bu)要錯過哦！

DWX型(xing)液(ye)壓支(zhi)(zhi)柱(zhu)(zhu)是一種新(xin)一代(dai)工作面(mian)(mian)單體(ti)支(zhi)(zhi)護(hu)設(she)備(bei)(bei)(bei)，其不僅可(ke)用于(yu)機(ji)械化普(pu)采(cai)工作面(mian)(mian)的配套支(zhi)(zhi)護(hu)設(she)備(bei)(bei)(bei)、綜(zong)采(cai)工作面(mian)(mian)的端(duan)頭支(zhi)(zhi)護(hu)設(she)備(bei)(bei)(bei)、巷道掘進(jin)工作面(mian)(mian)超前(qian)支(zhi)(zhi)護(hu)設(she)備(bei)(bei)(bei)，也可(ke)用于(yu)1300mm以下(xia)的薄煤層炮采(cai)工作面(mian)(mian)支(zhi)(zhi)護(hu)設(she)備(bei)(bei)(bei)。隨著DWX型(xing)液(ye)壓支(zhi)(zhi)柱(zhu)(zhu)的推(tui)廣應用，它的柱(zhu)(zhu)塞懸浮、密(mi)封(feng)脹緊、密(mi)封(feng)補償等(deng)技(ji)術特點已被社(she)會(hui)(hui)了(le)解和認識(shi)，它的無(wu)內泄(xie)漏、無(wu)圓弧(hu)焊(han)縫等(deng)安全理念也已被社(she)會(hui)(hui)接受，并(bing)被社(she)會(hui)(hui)譽為“生命支(zhi)(zhi)柱(zhu)(zhu)”和“礦工生命的保護(hu)神”。也有人把DWX型(xing)懸浮式單體(ti)液(ye)壓支(zhi)(zhi)柱(zhu)(zhu)形象地比喻(yu)為“以柔克(ke)剛(gang)，太極功(gong)夫(fu)”，也恰恰說明(ming)了(le)其支(zhi)(zhi)撐力大的特點。

煤(mei)(mei)(mei)礦(kuang)(kuang)支(zhi)(zhi)柱(zhu)(zhu)在(zai)正(zheng)常(chang)工(gong)(gong)(gong)作(zuo)中(zhong)，額定(ding)阻力(li)(li)是由安(an)(an)全閥(fa)(fa)開啟(qi)壓(ya)(ya)(ya)力(li)(li)決定(ding)的(de)(de)(de)。安(an)(an)全閥(fa)(fa)開啟(qi)壓(ya)(ya)(ya)力(li)(li)高，支(zhi)(zhi)柱(zhu)(zhu)的(de)(de)(de)額定(ding)工(gong)(gong)(gong)作(zuo)阻力(li)(li)就(jiu)大(da)，支(zhi)(zhi)架對頂(ding)(ding)(ding)(ding)(ding)(ding)底(di)板(ban)(ban)接(jie)觸比壓(ya)(ya)(ya)要求越(yue)高；反之(zhi)，DW28普通單體(ti)(ti)液壓(ya)(ya)(ya)支(zhi)(zhi)柱(zhu)(zhu)價(jia)格(ge)(ge)多少(shao)，則小。而在(zai)煤(mei)(mei)(mei)礦(kuang)(kuang)實際使(shi)用過程中(zhong)，為了便(bian)于(yu)支(zhi)(zhi)柱(zhu)(zhu)管理，將安(an)(an)全閥(fa)(fa)的(de)(de)(de)開啟(qi)壓(ya)(ya)(ya)力(li)(li)調到30T，這(zhe)樣(yang)造(zao)成破碎頂(ding)(ding)(ding)(ding)(ding)(ding)板(ban)(ban)工(gong)(gong)(gong)作(zuo)面(mian)周期來壓(ya)(ya)(ya)時(shi)切頂(ding)(ding)(ding)(ding)(ding)(ding)這(zhe)排支(zhi)(zhi)柱(zhu)(zhu)幾乎無安(an)(an)全閥(fa)(fa)的(de)(de)(de)開啟(qi)，致使(shi)背頂(ding)(ding)(ding)(ding)(ding)(ding)條笆被壓(ya)(ya)(ya)斷(duan)，沿傾斜方(fang)向頂(ding)(ding)(ding)(ding)(ding)(ding)板(ban)(ban)發(fa)生波浪式的(de)(de)(de)撓曲(qu)破壞；時(shi)有發(fa)生局部冒(mao)(mao)頂(ding)(ding)(ding)(ding)(ding)(ding)事故。部分(fen)采(cai)用煤(mei)(mei)(mei)礦(kuang)(kuang)支(zhi)(zhi)柱(zhu)(zhu)支(zhi)(zhi)護(hu)采(cai)場與(yu)SGWD-17型適板(ban)(ban)輸送機組成回采(cai)工(gong)(gong)(gong)作(zuo)面(mian)，工(gong)(gong)(gong)作(zuo)面(mian)和巷寬(kuan)采(cai)用1.0米絞(jiao)接(jie)頂(ding)(ding)(ding)(ding)(ding)(ding)梁(liang)(liang)及(ji)(ji)齊(qi)柱(zhu)(zhu)齊(qi)梁(liang)(liang)正(zheng)懸式支(zhi)(zhi)護(hu)方(fang)式，與(yu)煤(mei)(mei)(mei)壁約(yue)0.5米寬(kuan)的(de)(de)(de)空(kong)(kong)(kong)頂(ding)(ding)(ding)(ding)(ding)(ding)距，DW42普通單體(ti)(ti)液壓(ya)(ya)(ya)支(zhi)(zhi)柱(zhu)(zhu)價(jia)格(ge)(ge)多少(shao)，使(shi)工(gong)(gong)(gong)作(zuo)面(mian)的(de)(de)(de)傘(san)檐有冒(mao)(mao)頂(ding)(ding)(ding)(ding)(ding)(ding)的(de)(de)(de)可(ke)能(neng)。因此，DW14普通單體(ti)(ti)液壓(ya)(ya)(ya)支(zhi)(zhi)柱(zhu)(zhu)價(jia)格(ge)(ge)多少(shao)，在(zai)破碎頂(ding)(ding)(ding)(ding)(ding)(ding)板(ban)(ban)條件下使(shi)用煤(mei)(mei)(mei)礦(kuang)(kuang)支(zhi)(zhi)柱(zhu)(zhu)時(shi)，應以可(ke)能(neng)減小壁面(mian)前(qian)空(kong)(kong)(kong)頂(ding)(ding)(ding)(ding)(ding)(ding)距離(li)和空(kong)(kong)(kong)頂(ding)(ding)(ding)(ding)(ding)(ding)時(shi)間。如果我們在(zai)日常(chang)的(de)(de)(de)管理工(gong)(gong)(gong)作(zuo)中(zhong)采(cai)用頂(ding)(ding)(ding)(ding)(ding)(ding)梁(liang)(liang)間套使(shi)大(da)板(ban)(ban)梁(liang)(liang)等措(cuo)施控制面(mian)前(qian)空(kong)(kong)(kong)頂(ding)(ding)(ding)(ding)(ding)(ding)，由于(yu)坑木(mu)消耗量大(da)，工(gong)(gong)(gong)序復雜(za)，后(hou)改用半精度(du)短頂(ding)(ding)(ding)(ding)(ding)(ding)梁(liang)(liang)，當面(mian)前(qian)空(kong)(kong)(kong)頂(ding)(ding)(ding)(ding)(ding)(ding)寬(kuan)度(du)達0.5米時(shi)，在(zai)排頂(ding)(ding)(ding)(ding)(ding)(ding)梁(liang)(liang)掛一架短頂(ding)(ding)(ding)(ding)(ding)(ding)梁(liang)(liang)作(zuo)臨時(shi)支(zhi)(zhi)護(hu)，黑(hei)龍江普通單體(ti)(ti)液壓(ya)(ya)(ya)支(zhi)(zhi)柱(zhu)(zhu)價(jia)格(ge)(ge)多少(shao)，短頂(ding)(ding)(ding)(ding)(ding)(ding)梁(liang)(liang)與(yu)配(pei)合使(shi)用，具有操作(zuo)方(fang)便(bian)，支(zhi)(zhi)護(hu)及(ji)(ji)時(shi)，節約(yue)木(mu)料等優點，從而有效(xiao)地解決了工(gong)(gong)(gong)作(zuo)面(mian)空(kong)(kong)(kong)頂(ding)(ding)(ding)(ding)(ding)(ding)寬(kuan)大(da)的(de)(de)(de)難題。
