PRODUCT INTRODUCTION 产品介绍

Edwards vacuum is a worldwide famous vacuum pump and pumping system manufacturer, headquartered in England. It is the first company to design and introduce dry vacuum pumps to

the market over 20 years ago and remains the world leader in the supply of dry vacuum pump

with over 100,000 installations worldwide.

Edwards公司是一家世界著名的真空泵和真空系统制造商，总部在英格兰。它是20多年前第一家设

计并将干式真空泵推向世界的公司，到目前为止在全球有150,000台干式泵的安装。

Edwards EDP series dry vacuum pump achieved Europe ATEX explosion proof licence and

acquired explosion test certification given by third party ERA (ITS). The vacuum pump can entail

10 bar pressure explosion test. Edwards公司EDP系列干式真空泵完全达到欧洲ATEX (Atmosphere Explosive) 安全防爆标准认证，

具有独立第三方ERA（ITS）机构颁发的爆炸测试认证。真空泵本体能承受10bar的爆炸测试.

• Non-contact claw

无接触爪式结构

• Self valving

自动排放功能

• High compression ratios

高压缩比

• No oil in swept volume

腔体中无油

Edwards’ three-stage reversed claw mechanism design ensures

short gas flow path, short distance between backing stage exhaust

and backward stage inlet and then maximum limit temperature

drop. Furthermore, the stage compression ratio is equality and

pressure change and temperature rising are smoothly. When

handling in solid entrain process, reversed mechanism of short

flow path, vertical design of EDP series dry pump and big

dimension inlet and outlet are all good for purging solid from pump

chamber.

Edwards三级逆向爪式机构的设计保证气体流道暂短，前级排气口与

后级进气口距离短，这种设计最大限度地减小了级间的气体温度降

低，同时，每级的压缩比均匀，压力变化平缓，温度上升平缓；对于

有固体颗粒存在的工艺，逆向机构的暂短流道加上EDP系列干泵的立

式设计，以及大尺寸的进气和排气口，都有利于固体颗粒被吹扫出泵

腔体。
