該泵是以循環(huán)水為工作流體，采用射流技術(shù)產(chǎn)生負(fù)壓而設(shè)計的一種新型真空抽氣泵，它不僅是一種真空抽氣裝置，同時還能向反應(yīng)裝置中提供循環(huán)冷卻水，該泵具有不用油、無污染、耐腐蝕、噪音低、方便靈活等特點。材料采用防腐機(jī)芯和不銹鋼機(jī)芯兩種型號；立式電機(jī)，泵體直接潛入水下，不需加引水，一機(jī)多用。
（1）一機(jī)多管作業(yè)，本機(jī)裝有三套抽氣頭，可單獨或并聯(lián)使用。
（2）噪音小，移動方便。
（3）無污染，本機(jī)箱體為聚氯乙稀塑料，外殼采用不銹鋼和冷板靜電噴塑殼兩種。

This Pump is of jet pump with circulating water asworking liquid and designed by negative pressure produced from spraying liqunid .It is ar new vacuumair pump, which can provide with circulating cooling water to the reaction of device at same time. The pump has the advantages lf unuse oil,non-pollrtion corrosion resisting, lower noise and easy movement, one machine with multi-usage.
（1）One machine with multi-pipe operation, Where three sets of air exhaustor are fixed and used independently or parallelly.
（2）Lower noise,Convenient movement.
（3）Non-pollution,The pump body is made of polyvinyl chloride （pvc）plastics,and the onter cover is of cold-rolled steel plate with backing finish.
