Pneumatic negative pressure water pumping method

The invention discloses a pneumatic negative pressure water pumping method, and particularly relates to the technical field related to negative pressure water pumping, and adopted equipment mainly comprises an air compressor, a large air storage tank, a small air storage tank, a pressure water storage tank and an air pressure vacuum generator. The pneumatic negative-pressure water pumping method has two working states of a negative-pressure water pumping operation working condition and a positive-pressure water drainage operation working condition, and the negative-pressure water pumping operation working condition and the positive-pressure water drainage operation working condition are repeatedly and circularly operated to achieve continuous water pumping. According to the pneumatic negative-pressure water pumping method, only a single power source of the air compressor is used, positive-pressure power and negative-pressure power are generated, high-pressure gas is adopted to generate negative pressure throu
