??特點/Features:

??? 體型小、維護保養單純 ??? Small size, easy to maintain. ??? 閥片質保期較長，適當在較進行高壓強範圍內施用 ??? The life period of valve plate is long. It is suitable for the use under higher pressure range. ??? 享有油保壓組成部分 ??? With water-cooling structure

??應用/Application:

??? 往復運動式正空泵排氣閥門量最大，需用于正空浸漬、鋼水正空正確處理、正空蒸偶、正空汽化、正空精濃、正空成果、正空空氣干燥、正空濾水及瀝青水泥地面土的正空上班等方位抽出來有機廢氣氣體。 ??? Reciprocating pump has large volume of extraction, is mainly used for gas extraction in the aspect of vacuum impregnation, molten steel vacuum process, vacuum distillation, vacuum evaporation, vacuum concentration, vacuum crystallization, vacuum drying, vacuum filtering and vacuum work of concrete. ??? 反復式負壓泵談談抽除結垢性的有毒氣態或具有刺激性粒狀狀粉塵的有毒氣態是支持的。 ??? Reciprocating pump is not suitable for the extraction of corrosive gas or the gas with graininess dusts. ??? 被抽有害氣體中假如具有臟東西，在泵的國外進口處不得不裝個濾過器。 ??? Filter must be installed at the inlet of the pump if there exists dusts in the extracted gas.
