The utility model relates to a sliding type water ring pump, composed of an exhaust pipe 1, an air inlet pipe 2, an impeller 3, an exhaust valve opening 4, an inlet valve opening 5, a sliding vane 6, and a pump case 7. The working principle is that when the pump is working outside air intake valve port 5 and 2 into the pump shell 7 from the air inlet pipe; the impeller 3 rotates to slide along the pump shell 7 out of 3, the pump shell form a vacuum zone 7, inhaled external gas, gas and water in the water ring is compressed through the exhaust the valve port 4 and 1 discharged from the exhaust pipe. The utility model has the advantages of greater vacuum, higher efficiency and air extraction capacity than the existing water ring pump.
