又稱阻(zu)(zu)(zu)(zu)火(huo)(huo)通(tong)(tong)(tong)(tong)(tong)氣(qi)(qi)(qi)(qi)帽(mao)(mao).阻(zu)(zu)(zu)(zu)火(huo)(huo)通(tong)(tong)(tong)(tong)(tong)氣(qi)(qi)(qi)(qi)罩. FZT-1型(xing)防爆(bao)阻(zu)(zu)(zu)(zu)火(huo)(huo)通(tong)(tong)(tong)(tong)(tong)氣(qi)(qi)(qi)(qi)帽(mao)(mao)是加油(you)站(zhan)，小(xiao)型(xing)油(you)罐透(tou)氣(qi)(qi)(qi)(qi)不可少(shao)配套設(she)備，是原設(she)計的更新換代產品。透(tou)氣(qi)(qi)(qi)(qi)帽(mao)(mao)連接形式(shi)有法蘭(lan)連接和螺紋(wen)連接兩種.通(tong)(tong)(tong)(tong)(tong)氣(qi)(qi)(qi)(qi)帽(mao)(mao)垂直安裝在油(you)罐的頂部。防爆(bao)阻(zu)(zu)(zu)(zu)火(huo)(huo)通(tong)(tong)(tong)(tong)(tong)氣(qi)(qi)(qi)(qi)帽(mao)(mao)的頂帽(mao)(mao)采用耐火(huo)(huo)不銹鋼(gang)(gang)鋼(gang)(gang)板(ban)表面噴塑，殼體為鑄鋁(lv)。阻(zu)(zu)(zu)(zu)火(huo)(huo)芯有不銹鋼(gang)(gang)波(bo)紋(wen)板(ban)，符合SY/T0511-96的技術要求。當(dang)油(you)罐料膨脹(zhang)或(huo)進油(you)時，即(ji)通(tong)(tong)(tong)(tong)(tong)過阻(zu)(zu)(zu)(zu)火(huo)(huo)芯波(bo)紋(wen)板(ban)向(xiang)外(wai)排(pai)氣(qi)(qi)(qi)(qi)。當(dang)油(you)罐內向(xiang)外(wai)放油(you)時又向(xiang)罐內吸(xi)氣(qi)(qi)(qi)(qi)，并(bing)阻(zu)(zu)(zu)(zu)止(zhi)一(yi)切火(huo)(huo)源從此通(tong)(tong)(tong)(tong)(tong)過，確保安全(quan)。應經常對通(tong)(tong)(tong)(tong)(tong)氣(qi)(qi)(qi)(qi)罩的阻(zu)(zu)(zu)(zu)火(huo)(huo)波(bo)紋(wen)板(ban)的透(tou)氣(qi)(qi)(qi)(qi)性進行檢查(cha)，保證良(liang)好的阻(zu)(zu)(zu)(zu)火(huo)(huo)，透(tou)氣(qi)(qi)(qi)(qi)性能。

通氣(qi)(qi)(qi)(qi)帽是(shi)減(jian)速器(qi)(qi)的(de)專用(yong)附件，是(shi)單(dan)向通氣(qi)(qi)(qi)(qi)塞(sai)(sai)和(he)塑料通氣(qi)(qi)(qi)(qi)防水閥，在設(she)備(bei)中(zhong)起(qi)作用(yong)。透(tou)氣(qi)(qi)(qi)(qi)塞(sai)(sai)的(de)設(she)計可(ke)以(yi)同時排(pai)出(chu)水蒸氣(qi)(qi)(qi)(qi)和(he)透(tou)氣(qi)(qi)(qi)(qi)。簡單(dan)來(lai)說就是(shi)用(yong)來(lai)通風的(de)，主要用(yong)來(lai)平衡(heng)減(jian)速器(qi)(qi)內(nei)(nei)外的(de)大氣(qi)(qi)(qi)(qi)壓(ya)力。減(jian)速機在室外或連續運轉(zhuan)時，溫(wen)度會變得(de)很高(gao)，減(jian)速機內(nei)(nei)部(bu)的(de)潤滑(hua)油(you)會氣(qi)(qi)(qi)(qi)化成氣(qi)(qi)(qi)(qi)體，當然會膨脹。為了不損壞減(jian)速器(qi)(qi)的(de)油(you)封或接頭，減(jian)速器(qi)(qi)*高(gao)處的(de)堵塞(sai)(sai)物在使用(yong)前應換上通風帽，以(yi)保證(zheng)減(jian)速器(qi)(qi)運轉(zhuan)時箱體內(nei)(nei)的(de)氣(qi)(qi)(qi)(qi)體排(pai)出(chu)。

而(er)且通(tong)(tong)氣(qi)(qi)帽(mao)處形成彎折的氣(qi)(qi)流通(tong)(tong)道，并且由于(yu)底板的通(tong)(tong)氣(qi)(qi)孔處設有**濾網，能夠得到有效措施防止外界環(huan)境(jing)中的粉塵(chen)進入減速機內部(bu)，避(bi)免出現上述粉塵(chen)封(feng)堵通(tong)(tong)氣(qi)(qi)帽(mao)、損壞齒輪(lun)軸(zhou)承。

以上是對(dui)行(xing)星減速(su)器中的通氣帽的作用介紹(shao)。
