??特點/Features:

??? 質量分數小、維修服務比較簡單 ??? Small size, easy to maintain. ??? 閥片質保期較長，非常適宜在較高壓力強空間內的使用 ??? The life period of valve plate is long. It is suitable for the use under higher pressure range. ??? 更具油冷凝結構設計 ??? With water-cooling structure

??應用/Application:

??? 往復式式負壓系統泵泄壓閥量最大，好用于負壓系統浸漬、鋼水負壓系統治療、負壓系統蒸偶、負壓系統蒸餾、負壓系統精濃、負壓系統凝結、負壓系統變干、負壓系統過濾器及瀝青c30混凝土土的負壓系統課外作業等等方面吸出其他氣體。 ??? 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. ??? 回轉式高壓氣泵這對抽除灼傷性的氣休或帶有顆粒劑狀臟東西的氣休不是適用人群的。 ??? Reciprocating pump is not suitable for the extraction of corrosive gas or the gas with graininess dusts. ??? 被抽有機廢氣氣體中如若含有積灰，在泵的原產處一定要還可以加裝活性炭過濾網。 ??? Filter must be installed at the inlet of the pump if there exists dusts in the extracted gas.
