 用途及特點(diǎn)[Applications & Features] |
|
 |
| 1、可直接從大氣壓起動抽氣 |
| Starting up directly from Atmosphere Pressure for Evacuation |
| 2、可單獨(dú)作低真空泵用，也可與其他高真空泵組合作前級泵用 |
| Used either solely as Rough Pumps, or in combination with other high vacuum pumps as Backing Pumps |
|
| 3、本系列產(chǎn)品廣泛應(yīng)用于冶金、化工輕工、醫(yī)藥、電子與半導(dǎo)體工業(yè) |
| They find wide application in the fields of metallurgy, chemical, light industry, medicinal, electronics and LSI industries. |
4、該泵不可用來抽含氧過高的、有毒的易爆的或與泵油發(fā)生化學(xué)作用
的或?qū)谏饘儆懈g作用的氣體也不可當(dāng)作壓縮機(jī)或傳輸泵使用 |
| They can not be used for evacuating the oxygenic, poisonous and explosive gases and gases which can react with pump oil easily. Neither can they be used as compressor and transmission pump. | |
