對于有防爆要求的場合,用戶在選型、訂貨時應(yīng)按所分離的腐蝕介質(zhì)和名稱、濃度、溫度以及其它因素(如雜質(zhì)、PH值、是否含有空氣或水,流動或靜止)等理化數(shù)據(jù),根據(jù)分離介質(zhì)的特性提出離心機的防爆配置和措施,滿足防爆要求。
滿足防爆要求(和滿足防腐要求),是離心機選型的首要條件!
Explosion-proof Tethnology of the Centrifuge
For the centrifuge to be used in space involving ex-proof requirements, the user shall select and order proper type/model of centrifuge depending on ex-proof configuration and measures so specified based on features of separation medium as well as its physical and chemical properties including corrosive medium and its concentration, temperature and other factors (e.g. impurity, PH value, with or without air, flowing or static
Meeting ex-proof requirements (and satisfying anti-corrosion specification) is the thing of first priority to consider while selecting the centrifuge of right model/type!
