Magnetic suspension water ring vacuum pump

The invention relates to a magnetic suspension water ring vacuum pump, and belongs to the technical field of coal mine safety. Comprising a pump cylinder, an air suction pipe and an exhaust pipe are arranged on the pump cylinder, a rotating shaft is arranged in the pump cylinder, the two ends of the rotating shaft are fixed in the pump cylinder through radial magnetic suspension bearings, and an impeller and a magnetic suspension motor are arranged on the rotating shaft; the magnetic suspension motor drives the rotating shaft to rotate, and coal seam gas enters the impeller through the suction pipe and the pump cylinder and is discharged out of the pump cylinder through the exhaust pipe under the action of the impeller. By using the magnetic suspension motor, the utilization efficiency of the water ring vacuum pump is improved, the energy consumption in the operation process of the water ring vacuum pump is reduced through the magnetic suspension bearing, and the operation safety is improved. 本发明涉及一种磁悬浮水环真空泵，
