又(you)稱阻(zu)(zu)(zu)火(huo)(huo)通(tong)(tong)氣(qi)帽(mao).阻(zu)(zu)(zu)火(huo)(huo)通(tong)(tong)氣(qi)罩. FZT-1型防(fang)爆阻(zu)(zu)(zu)火(huo)(huo)通(tong)(tong)氣(qi)帽(mao)是加油(you)站，小型油(you)罐(guan)(guan)(guan)透(tou)氣(qi)不(bu)可(ke)少配套設(she)備，是原設(she)計的更新換代產品(pin)。透(tou)氣(qi)帽(mao)連接形式有法蘭連接和螺(luo)紋(wen)連接兩種.通(tong)(tong)氣(qi)帽(mao)垂直安裝在(zai)油(you)罐(guan)(guan)(guan)的頂(ding)(ding)部。防(fang)爆阻(zu)(zu)(zu)火(huo)(huo)通(tong)(tong)氣(qi)帽(mao)的頂(ding)(ding)帽(mao)采(cai)用耐火(huo)(huo)不(bu)銹鋼鋼板表面噴(pen)塑，殼體為鑄鋁。阻(zu)(zu)(zu)火(huo)(huo)芯有不(bu)銹鋼波(bo)紋(wen)板，符合SY/T0511-96的技術要求。當油(you)罐(guan)(guan)(guan)料膨脹(zhang)或(huo)進(jin)油(you)時，即通(tong)(tong)過阻(zu)(zu)(zu)火(huo)(huo)芯波(bo)紋(wen)板向(xiang)外排氣(qi)。當油(you)罐(guan)(guan)(guan)內向(xiang)外放(fang)油(you)時又(you)向(xiang)罐(guan)(guan)(guan)內吸氣(qi)，并阻(zu)(zu)(zu)止一切火(huo)(huo)源從(cong)此通(tong)(tong)過，確保(bao)安全。應經常對通(tong)(tong)氣(qi)罩的阻(zu)(zu)(zu)火(huo)(huo)波(bo)紋(wen)板的透(tou)氣(qi)性進(jin)行檢查，保(bao)證良好的阻(zu)(zu)(zu)火(huo)(huo)，透(tou)氣(qi)性能(neng)。

通氣(qi)(qi)(qi)帽(mao)是(shi)(shi)減(jian)(jian)速(su)(su)(su)器(qi)的(de)專用(yong)附件，是(shi)(shi)單向(xiang)通氣(qi)(qi)(qi)塞和(he)塑料通氣(qi)(qi)(qi)防水閥，在(zai)設備中(zhong)起(qi)作用(yong)。透(tou)氣(qi)(qi)(qi)塞的(de)設計可以同時排出水蒸氣(qi)(qi)(qi)和(he)透(tou)氣(qi)(qi)(qi)。簡單來(lai)說就是(shi)(shi)用(yong)來(lai)通風(feng)的(de)，主要用(yong)來(lai)平衡(heng)減(jian)(jian)速(su)(su)(su)器(qi)內外(wai)的(de)大氣(qi)(qi)(qi)壓力。減(jian)(jian)速(su)(su)(su)機在(zai)室外(wai)或連續運(yun)轉時，溫度(du)會(hui)變得很高(gao)，減(jian)(jian)速(su)(su)(su)機內部的(de)潤滑油會(hui)氣(qi)(qi)(qi)化成(cheng)氣(qi)(qi)(qi)體，當然會(hui)膨脹(zhang)。為了(le)不損壞減(jian)(jian)速(su)(su)(su)器(qi)的(de)油封或接頭，減(jian)(jian)速(su)(su)(su)器(qi)*高(gao)處的(de)堵(du)塞物在(zai)使用(yong)前應換上通風(feng)帽(mao)，以保(bao)證減(jian)(jian)速(su)(su)(su)器(qi)運(yun)轉時箱體內的(de)氣(qi)(qi)(qi)體排出。

而且(qie)通(tong)(tong)氣帽處(chu)形(xing)成彎折的氣流通(tong)(tong)道，并且(qie)由(you)于底板的通(tong)(tong)氣孔處(chu)設有**濾網，能(neng)夠(gou)得到有效措施(shi)防止外界環(huan)境中的粉塵進入減(jian)速(su)機內(nei)部，避免出(chu)現上述粉塵封堵(du)通(tong)(tong)氣帽、損壞齒輪軸承。

以上(shang)是對行星(xing)減速(su)器(qi)中(zhong)的通氣(qi)帽(mao)的作(zuo)用介紹(shao)。
