Edwards推出了新EV单级油式机械泵

爱德华公司新近推出了新一系列单级油式机械泵。新一系列的产品提供了可靠、高速低压运行的能力,可以适用于包括熔炉、真空干燥、热力塑型、食品处理和包装等广泛的领域。

相比EV20和EV40,新系列泵的体积相对较小,因而也就适用于科学研究范围。在结合了性能提高、维修费用低廉的旋转叶片技术和前瞻性的环境设计,BOC爱德华公司带给了市场一款经济的单级真空的解决方法。

与其它竞争产品不同,EV类产品提供从大气到绝对真空的连续操作。此外,每10毫巴*高可达6kg/h的优质水蒸气容许量,也保证了一致不间断的运转。其他关键的优点还包括非常小的震动和噪音,即使是*大的EV630泵也小于83分贝;同时,高效的烟雾过滤器也可以保证排气装置中**量的油渗出,从而保证经济的运转和环境的保护。所有的泵都采用了空气冷却,从而节约了资金和运转成本。

泵可以被个别提供也可以作为与BOC爱德华公司提前制定标准组合的部分以此来提高泵的机械性能。同时支持使用双重频率电流。

New EV Range of Single-Stage Rotary Vane Pumps

BOC Edwards, has launched a new range of single-stage rotary vane pumps. The EV range offers reliable, high-speed low-pressure performance suitable for a wide range of applications including furnaces, vacuum drying, thermoforming, food processing and packaging.

The smaller pumps, such as the EV20 and EV40, are also suitable for use in scientific applications. A combination of proven, low-maintenance rotary vane technology and environmentally-aware design, BOC Edwards brings to market an economical single-stage vacuum solution for industry. 

Unlike some competitive products the EV range provides continuous operation from atmosphere to ultimate vacuum. This, coupled with good water vapour tolerance of up to 6 kg/h at 10 mbar, ensures a consistent, un-interrupted process. Other key benefits include low vibration and noise even on the largest EV630 pump (less than 83 dB(A)) and highly efficient mist filters that ensure minimal oil discharge from the exhaust - pro-viding economical operation and environmental protection. All pumps are air cooled, saving the capital and operating costs associated with providing cooling water. 

Pumps can be supplied individually (there are nine variants offering a range of speeds from 20 to 750m3/h) or as part of a pre-engineered combination with BOC Edwards proven mechanical booster pumps to increase pumping speed and ultimate vacuum. Dual frequency, wide band motor options ensure compatibility with power sources worldwide.
