以此在潔凈車間裝修中，要嚴格控制建筑物的耐火等級，設計時將建筑構件的耐火性能與廠房的耐火等級相配套，從而大大減少了火災發(fā)生的可能性。我們必須注意裝修材料的燃燒性能，盡量減少使用一些高分子合成材料，以避免火災發(fā)生時產(chǎn)生大量煙氣，不利于人員逃生。另外，要對電氣線路的穿管做嚴格要求，在有條件的地方要盡量使用鋼管，保證電氣線路不成為火災蔓延的途徑。綜上所述，潔凈車間對空氣的溫度，濕度潔凈度要求較高。設計者要根據(jù)工藝要求，生產(chǎn)潔凈度級別合理選用建筑材料，考慮耐火性能，從而達到GMP設計要求。

不銹鋼磁力泵隔離套的材料選擇隔離套是保證磁力泵無泄漏的承壓部件，也是作為介于內(nèi)、外磁轉子之間的靜止的密封隔離件。隔離套作為的密封部件、主要承受著泵在工作時產(chǎn)生的內(nèi)部壓力。出現(xiàn)強度的考慮，一般由金屬材料制成。由于隔離套在高速交變磁場中工作，因此產(chǎn)生嚴重的發(fā)電效應，即磁渦流損失、材料的導電性能越好，截面積越大，轉速越高，渦流損失就越大。隔離套盡量選擇非鐵磁性的、電阻率比較高的材料。常用的金屬材料有奧氏體不銹鋼、鈦合金、哈氏合金等。

也是螺桿式冷水機的主要工作原理。螺桿式冷水機的應用螺桿式冷水機的功率與相比渦旋式的相對較大，主要應用于空調(diào)系統(tǒng)或大型工業(yè)制冷方面螺桿式冷水機的分類：螺桿式冷水機按照散熱方式的不同可分為水冷螺桿式冷水機和風冷螺桿式冷水機產(chǎn)品選用要點1.冷水機組的選用應根據(jù)冷負荷及用途來考慮。對于低負荷運轉工況時間較長的制冷系統(tǒng)，宜選用多機頭活塞式壓縮機組或螺桿式壓縮機組，便于調(diào)節(jié)和節(jié)能。選用冷水機組時，優(yōu)先考慮性能系數(shù)值較高的機組。
