槽)等設(shè)施液面的很大垂直距離。離心泵安裝高度過高會導致汽蝕現(xiàn)象，此時泵啟動后若不能在規(guī)定時間內(nèi)停泵，將會在短時間內(nèi)導致葉輪、泵殼等產(chǎn)生蜂窩狀孔洞而使泵產(chǎn)生噪聲、振動或被損壞。同時，汽蝕現(xiàn)象還會進一步形成電化學腐蝕，加速金屬剝蝕的破壞速度。導致汽蝕現(xiàn)象的原因是泵的安裝高度不合適，致使葉輪葉片入口附近的液體壓力低于輸送溫度下液體的飽和蒸汽壓力時，液體就會在低壓區(qū)汽化形成氣泡。氣泡隨著葉輪高速旋轉(zhuǎn)，運動到液體壓力較高處時被高壓液體壓破重新凝結(jié)而形成空穴。這樣，周圍的液體會以極高的速度和頻率沖過來補充氣泡凝結(jié)留下的空穴。若氣泡在葉輪、泵殼表面或附近被壓破，高速和高頻率沖過來的液體形成局部沖擊高壓，導致金屬表面出現(xiàn)蜂窩狀孔洞而使金屬產(chǎn)生疲勞破壞。(三)產(chǎn)生振動或異常聲音1．安裝不牢固，緊固件松動離心式消防泵啟動后，葉輪會高速旋轉(zhuǎn)。若離心式消防泵的安裝不牢固，或者長時間運轉(zhuǎn)導致緊固件松動，會使泵在運轉(zhuǎn)過程中產(chǎn)生振動、噪聲，甚至在短時間被損壞。2．泵體與泵軸安裝不正液體經(jīng)過消防泵獲得的有效能量是從泵的葉輪獲得的，而葉輪獲得的能量是從泵軸得到的(公眾號:泵管家)，泵軸獲得的能量又是由電動機提供的。九江倉庫消防器械銷售江西成濟消防裝飾工程有限公司懷著一顆感恩的心。</p><div

鶴壁消防水帶不銹鋼消防箱優(yōu)點：不銹鋼消防箱的儲物功能都在火災(zāi)時就已經(jīng)儲存，因此在正常的使用環(huán)境中，消防箱在消防中的使用有著非常重要的作用。消防箱里的材料都是可以移動的，材料自帶導電殼體，在防火分隔方面起著很大的作用，所以不管你用什么材料，對材料有一個很好的固定需求。簡單易學、易學，存儲物品容易，一鍵支持到位，并且有真正意義的文字提示。不用顧此失彼。但是相對于在建筑消防設(shè)施以及消防應(yīng)急管道上使用的消火栓，消防水帶的密封性已經(jīng)是大問題了，整個消防栓的芯層都采用了密封的結(jié)構(gòu)，其密封面相當薄，在**外層的一般密封膠板上只可以看到薄的兩側(cè)?；A(chǔ)剛開始的時候，建設(shè)項目應(yīng)當在什么項目開工前進行規(guī)劃設(shè)計，然后在規(guī)劃的各個階段進行施工安裝與驗收。第二節(jié)：土建基礎(chǔ)就是地基了。鶴壁消防水帶3現(xiàn)在不銹鋼消防箱較新的數(shù)據(jù)顯示，從加工制造到安裝的所有時間全部節(jié)省了，減少了的費用。不銹鋼消防箱就是消防員提前按照消防規(guī)范要求制作的，方便專業(yè)的人員就能拆裝到位。本人的消防箱如何設(shè)置?在消防行業(yè)中，安全、舒適、節(jié)能是一切消防設(shè)備的必修課，然而消防箱的重要性卻很難量化，怎樣避免類似的情況發(fā)生。消防箱之所以要設(shè)置。</p><p> 但仍然不能正常輸送消防用滅火劑。5．泵的葉輪逆轉(zhuǎn)離心式消防泵往往采用電動機驅(qū)動。若電動機的正負極接反了，就會導致泵的葉輪逆轉(zhuǎn)，尤其是新安裝的或維修、更換的泵。泵的葉輪逆轉(zhuǎn)，就不能將液體壓送到出口管路，而吸入口不能形成一定的真空，從而不能保證泵啟動后正常吸入、排出液體。6．泵進出口管線設(shè)計存在缺點與泵連接的吸入和壓出管路的直徑應(yīng)與泵的性能參數(shù)相匹配，通常吸入管徑稍大于壓出管徑。若泵出口管線設(shè)計不夠合理，直徑過大，會導致泵的輸出流量達不到工藝要求，從而影響泵的正常輸出液體。當吸入管路阻力過大時，消防泵吸入管路的真空表雖然有很大的真空度，但泵不能吸入液體，從而導致壓出管路無液體流出。若壓出管路阻力太大或葉輪旋轉(zhuǎn)受阻，消防泵壓出管路的壓力表雖然有壓力，但壓出管路也會沒有液體排出。7．濾網(wǎng)、底閥或葉輪堵塞濾網(wǎng)是為了防止雜質(zhì)被吸入泵內(nèi)而使管路、葉輪等出現(xiàn)堵塞或磨損;底閥是單向閥，防止液體從泵內(nèi)沿吸入管流出。若濾網(wǎng)、底閥或葉輪等部位存在堵塞現(xiàn)象，同樣會導致泵雖然啟動了，但不會有液體吸入，也不會有液體壓出。(二)汽蝕現(xiàn)象導致泵損壞離心泵的實際安裝高度不能超過其很大允許安裝高度，即泵吸入口距離吸入池。江西成濟消防裝飾工程有限公司艱苦奮斗，揚長避短。</p><div

系統(tǒng)滅火機理考點水噴霧系統(tǒng)滅火機理水噴霧的滅火機理主要是表面冷卻、窒息、乳化和稀釋作用。第二節(jié)系統(tǒng)分類考點1系統(tǒng)分類水噴霧滅火系統(tǒng)按啟動方式可分為電動啟動水噴霧滅火系統(tǒng)和傳動管啟動水噴霧滅火系統(tǒng)?？键c2傳動管啟動水噴霧滅火系統(tǒng)在北方寒冷地區(qū)，應(yīng)在傳動管的較低點設(shè)置冷凝器和汽水分離器，以保證傳動管不會被冷凝水結(jié)冰堵塞第三節(jié)系統(tǒng)工作原理與適用范圍考點1防護冷卻的適用范圍以防護冷卻為目的的水噴霧系統(tǒng)主要適用于以下范圍：1、可燃氣體和甲、乙、丙類液體的生產(chǎn)、儲存、裝卸、使用設(shè)施和裝置的防護冷卻。2、火災(zāi)危險性大的化工裝置及管道，如加熱器、反應(yīng)器、蒸餾塔等的冷卻防護?？键c2設(shè)置場所固定式水噴霧滅火系統(tǒng)可設(shè)置在以下場所：1、建筑內(nèi)燃油、燃氣的鍋爐房，可燃油油浸電力變壓器室，充可燃油的高壓電容器和多油開關(guān)室，自備發(fā)電機房；2、單臺容量在40MW及以上的廠礦企業(yè)可燃油油浸電力變壓器，單臺容量在90MW及以上可燃油油浸電廠電力變壓器，單臺容量在125MW及以上的**變電所可燃油油浸電力變壓器。第四節(jié)系統(tǒng)設(shè)計參數(shù)考點1水霧噴頭的工作壓力用于滅火控火目的時，水霧噴頭的工作壓力不應(yīng)小于；用于防護冷卻目的時。江西成濟消防裝飾工程有限公司勤勉進取，決不過得且過。九江倉庫消防器械銷售</p><p

2、供電電源：單相交流電85-265V，45-63Hz，功率小于20W；直流供電。3、應(yīng)安裝在水平管道較低處和垂直向上處，避免安裝在管道的較高點和垂直向下處。4、測量管道內(nèi)必須完全充滿液體。5、流量計前方**少要有5D(D為流量計內(nèi)徑)長度的直管段，后方**少要有3D(D為流量計內(nèi)徑)長度的直管段。6、測量一般的介質(zhì)時，電磁流量計的滿度流量可以在測量介質(zhì)流速～12m/s范圍內(nèi)選用，范圍比較寬。選擇儀表規(guī)格（口徑）不一定與工藝管道相同，應(yīng)視測量流量范圍是否在流速范圍內(nèi)確定，即當管道流速偏低，不能滿足流量儀表要求時或者在此流速下測量準確度不能保證時，需要縮小儀表口徑，從而提高管內(nèi)流速，得到滿意測量結(jié)果。測量導電性良好的液體，通常較大流速不超過5m/s，經(jīng)濟流速范圍在～3m/s。測量低電導率的流體，則盡可能選擇低流速，原因是流速提高流動噪聲會增加，從而導致流量信號輸出晃動現(xiàn)象。7、一般傳感器供貨時已經(jīng)設(shè)計了接地電極，但是當外界電磁場干擾較大時，電磁流量計應(yīng)另行設(shè)置接地裝置，接地線采用截面積大于4mm2的多股銅線，接地線埋入潮濕地下1m，接地電阻小于10Ω，不能和電機或其他設(shè)備共用地線。九江倉庫消防器械銷售</p><p
