Energy saving comparison between water ring pump and oil screw vacuum pump used in CNC machining center
Hanbell PA1300VSD + vacuum pump with 22KW motor
When the vacuum demand is reduced, the speed can be reduced automatically thanks to frequency converter, and the minimum load can be reduced to 5 kW.
If the water ring vacuum pump with similar pumping speed is selected. It totally needs 5 sets with pumping speed 1600, and the power consumption is 45kw.
Energy saving comparison: variable frequency screw vacuum pump PA1300VSD+ VS water ring pump
Electric charge for one year（RMB 0.8/kWh 6000h）
PA oil-less screw vacuum pump
Water ring pump
Compared to Water ring pump, PA energy saving 51.1%
