2BE·SK系列水环真空泵带一级大气喷射泵真空机组

2BE·SK SERIES OF VACUUM SYSTEMS SETTED UP WITH A WATER RING PUMP AND A JET PUMP

该类机组最低吸入压力（绝压）可达1.5-2Pa在吸入压力为-0.096MPa－-0.098MPa之间仍有较大抽速，因此适合于在较高真空下工作。

The lowest inlet pressure of this kind of system can arrive at 1.5-2kPa(absolute pressure). When the suction pressure is between –0.096 and –0.098MPa, its pumping speed is still larger, so it is generally used to working in higher vacuum.
