VACUUM WATER PUMPING METHOD CAPABLE OF SAVING ENERGY REQUIRED TO OPERATE A PUMP MAXIMIZING EFFICIENCY WHEN WATER IS PUMPED FROM THE LOWER PART TO THE UPPER PART

摘要

PURPOSE: A vacuum water pumping method is provided to reduce a construction cost due to small capacity of a pump facility for industry and drastically reduce power consumption when a pump operates.;CONSTITUTION: A vacuum water pumping method is as follows. Air from a closed vessel(2) assembled to the vacuum water pumping device is sucked by a suction pump and is discharged to the atmosphere. Water is sucked from lower water(8) and upper water(6) along a water inlet pipe(15) and a water discharge pipe(10), reaches the inner water surface(16) of the closed vessel and forms a vacuum space(1). An atmosphere blocking valve(14) is locked to separate the vacuum space from the atmosphere to generate negative pressure in the vacuum space.;COPYRIGHT KIPO 2012
