電機防爆閥門控制箱

型號:BXK

產品時間(jian):2022-08-16

簡要描述:

基本原理當閥門處于關位置時,開啟電源開關,電源指示燈亮,閥門關到位指示燈和夾緊到位指示燈同時點亮。需要開閥時,按下閥門松開按鈕,松開夾緊電機正轉,帶動松開/夾緊機構放松動作(夾緊到位指示燈熄滅)

電機防爆閥門控制箱電機

1.1區(qu)(qu),2區(qu)(qu)爆炸性氣體環境.

2.適用于IIA、IIB、IIC級爆炸性氣體環境;

3.20區(qu),21區(qu),22區(qu)可(ke)燃性(xing)粉塵環境.

4.適用于溫度組別為(wei)T1—T6的環境.

爆(bao)炸性氣(qi)體環境危險區域的劃分
  不同的(de)國家和(he)(he)地區(qu)(qu)(qu),按各自(zi)的(de)標準劃分爆炸(zha)(zha)危險(xian)區(qu)(qu)(qu)域。我(wo)國根據(ju)爆炸(zha)(zha)性氣體(ti)混合物出現(xian)的(de)頻繁程(cheng)度(du)和(he)(he)持續時間,將爆炸(zha)(zha)性氣體(ti)環境分為(wei)O區(qu)(qu)(qu)、1區(qu)(qu)(qu)和(he)(he)2區(qu)(qu)(qu)。(與IEC國際(ji)電工 *)
  0區:連(lian)續出現或長期出現爆(bao)炸性氣體(ti)混合物的(de)環境。
  1區:在正常運行時可能(neng)出(chu)現爆炸性氣體混合(he)物的環境(jing)。
  2區:在正常運行(xing)時不(bu)可能出現爆(bao)(bao)炸性氣體(ti)混合物(wu)的環境(jing)或即使出現也僅是短(duan)時存在的爆(bao)(bao)炸性氣體(ti)混合物(wu)的環境(jing)。
  0區一般只存在(zai)于密封的容器,貯(zhu)罐等內部氣體(ti)空間,在(zai)實(shi)際設計過程中(zhong)1區也很(hen)少存在(zai),大多(duo)數(shu)情況(kuang)屬于2區。
  1.2防爆電器設備分為二類:
  Ⅰ類煤礦井下用電氣設備
  Ⅱ類除礦井以外的場合使用(yong)的電氣(qi)設(she)備
  1.3Ⅱ類(lei)電氣設備,按(an)其適用(yong)于(yu)爆炸性氣體混合物 大試(shi)驗安全間隙或 小點燃電流比,分為ⅡA,ⅡB,ⅡC三(san)類(lei);并按(an)其 高表(biao)面溫(wen)度分為T1-T6六組。
  1.4爆炸(zha)性氣體(ti)混合物按(an)引(yin)燃溫(wen)度分(fen)組,見表1。
  1.5爆炸性(xing)氣體混(hun)合物,按其 大試驗(yan)安全間隙(xi)(MESG)或 小點燃電流比(MICR)分(fen)級,見表2。

主要結構和工作原理

1、主要結構由面板、控(kong)制按鈕、電源(yuan)開關(guan)、指(zhi)示燈、交流接(jie)觸器等(deng)構成。可以完成閥門的啟閉(bi)和松開、夾(jia)緊的操作,狀態指(zhi)示、電機(ji)過載保護等(deng)功能。電動(dong)眼鏡(jing)閥操作流程為:閥門開閥門關(guan)

1.閥板松開到位

2.閥門開啟到位2

3.閥板夾緊到位
