爆鋼絲繩電動葫蘆根據(jù)GB3836．1－2000《性氣體環(huán)境用防爆電氣設(shè)備部分：通用 要求》及GB3836．2－20000《性氣體環(huán)境用防爆電氣設(shè)備第二部分：隔爆型“d”》的規(guī)定，電 機、電器為隔爆型，防爆爆級別為 Exd I CT4B時，運行機機構(gòu)進(jìn)行防火花處理。整機符合．JB／T10222 2001《防爆鋼絲繩電動葫蘆》的規(guī)定，防爆等級分別為 Exd BT4、 Exd CT4。本機可與車間固定 懸掛軌道配合單獨使用，也可與LXB防防爆電動懸掛單梁、LB防爆電動單梁、防爆葫蘆雙梁配套使 用。其起重量為1t－32t。工作環(huán)境溫度為－25C－40C。 According to GB 3836 1-2000(explosive gas atmosphere use explosion-proof electric equipment Part 1: common requirements)and GB38362-2000(explosive gas atmosphere use explosion-proof electric equipment Part 2: flameproof type d), motor and electrical appliances of explosion proof wire rope electric hoist are explosion proof type. When explosion proof grade is Exd I[ CT4, trelling mechanism should do spark proof treatment. The whole machine meets standards of JB/t10222-2001(explosion proof wire rope electric hoist ), explosion proof grade he Exd I BT4 and Exd II CT4 two kinds. It can be installed under workshop fixed suspending rail to use individually and can be used together with LXB explosion proof electric suspension single girder crane, LB explosion proof electric single girder crane and explosion proof electric hoist double girder crane. The capacity is 1 t-32t, wong environment temperature is-25 c-40c HB型防爆鋼絲繩電動葫蘆適用于工廠內(nèi)具有防爆級別不高于B級或C級，引燃溫度組別不低于 T4（135C）組的可燃性氣體、蒸蒸汽與空氣形成的性氣體環(huán)境中，所適用的危險區(qū)域為1區(qū)或 2區(qū)，不適用于0區(qū)。 HB series explosion proof electric hoist adapts to the environment in factory that he explosive gas formed by inflammable gas, steam and air of which explosion proof grade is less than B grade or C grade and ignition group is more than T4 (135C) group And the explosion proof electric hoist adapts to l area or 2 area, not 0 area. 注：0區(qū)：在正常情況下，性氣體混合物連續(xù)地、短時間頻繁地出現(xiàn)或長時間存在的場 所 Notes: 0 area: Under normal circumstances, the situation that explosive gas mixture appear continuously in a very short time or exist for a long time 1區(qū)：在正常情況下，性氣體混合物有可能出現(xiàn)的場所。 1 area: Under normal circumstances, the situation that explosive gas mixture may be appear. 2區(qū)：在正常情況下，性氣體混合物不能出現(xiàn)，僅在不正常情況下既有可能發(fā)生設(shè)備故 障或誤操作情況下，偶爾短時間出現(xiàn)的場所。 2 area: Under normal circumstances, explosive gas mixture can not appear. But under abnormal circumstances that equipment is out of order or misoperation takes place, the explosive gas mixture appears ocionally in a short time. 防爆鋼絲繩電動葫蘆所適用的危險氣體舉例見下表，未列入表內(nèi)的其它危險氣體見 GB3836．1之附錄。 Dangerous gas that explosion proof electric hoist can be used in is listed as follows. Refer to the appendix of GB 3836. I for other dangerous gas that has not been listed into the follow table.
