▲直联旋片真空泵是在旋片式真空泵的基础上经过结构、材料和制造工艺上重大改革后的一种新泵种。
Monoblock Rotary-vane Vacuum Pump is a kind of new pump, which is designed on the basis of rotary-vane vaccum pump through major reforms of structures, materials and manufacturing process.
▲直联泵具有体积小、质量轻、振动小、噪音低等特点，适用于安装在精密仪器设备上使用。
Monoblock pump has the features such as small size, light weight, small vibration and low noise etc. It is suitable for the installation in the use of precision instrument and equipment.
▲直联泵采用三相或单相交流电机直联驱动。
Monoblock pump is directly driven by three-phase or single-phase AC motor.
可单独使用，亦可作为各类真空系统的前级泵。
It can be used alone, and also can be used as prepump for various vacuum system.
直联泵附有气镇装置，可以抽出含有一定数量的可凝性气体。
Accompanied by gasballast equipment, monoblock pump could extract a quantity of condensable gas.
▲直联泵不能应用于抽出尘埃及腐蚀性、易爆性气体，不得用作压缩泵或输送泵使用。
Monoblock pump can not be used as compression pump or delivery pump to extract dusts, corrosive and explosive gas.
