PURPOSE: A lifting type automatic pneumatic pump is provided to locate pneumatic tanks on a pumping subject by using floating elements without using any additional primary pump, thereby reducing energy consumption and omit any installation area for the pneumatic tanks. CONSTITUTION: A lifting type automatic pneumatic pump includes floating elements(15) attached in every direction at an upper part of a lifting box(14) for raising an equipment, a plurality of cylindrical pneumatic tanks(1T,2T) assembled in the lifting box and mounted with an air pressure(12) and an automatic controller(13), water introducing valves(2,2') and draining valves(3,3') mounted at a lower part of the tanks for automatically injecting a pumping subject material(16) into the tanks, and upper and lower limit sensors(9,9',7,7') mounted at random positions, wherein air injection by the compressor is continued or stopped under the control of the automatic controller, so that the tanks are automatically drive to operate or stop operating alternately via pressure control valves(11,11') and air discharging valves(10,10'). |
