As shown in fig. 1-3, the present invention provides a technical solution: the utility model provides a two-way circulation piston pneumatic tanker aircraft, including pneumatic means 2, pneumatic means 2 includes air pump 207, in this embodiment, install high-pressure gas cylinder in the air pump 207, make air pump 207 outside blowout highly-compressed air, air pump 207 one end fixedly connected with holds liquid case 204, the dry storehouse of liquid case 204 one side fixedly connected with 202, it is 208 that liquid case 204 bottom fixedly connected with communicates pipe, 208 one end fixedly connected with air measuring box 209 communicates pipe, air measuring box 209 one side fixedly connected with magnetic field sensor 210, the inside magnetism floating bead 203 that has placed of air measuring box 209, and air measuring box 209 top and outside are linked together. In this embodiment, the liquid containing tank 204 contains liquid which is difficult to be compressed and difficult to dissolve air, such as water, etc., because the liquid containing tank 204 and the air measuring tank 209 are connected by the communicating pipe 208, so that they form a communicating device, in general, the liquid containing tank 204 and the air measuring tank 209 have the same liquid level and keep unchanged, so that the height of the magnetic floating beads 203 floating on the liquid level also keeps unchanged, one end of the drying chamber 202 is fixedly connected with the air inlet valve 211, in this embodiment, the air inlet valve 211 is an electronic valve and is electrically connected with the oiling machine control system, when the air inlet valve 211 is closed, the air pump 207 pumps compressed air into the liquid containing tank 204, so that the air pressure above the liquid containing tank 204 is increased; the air pressure above the liquid level of the air measurement box 209 is always normal atmospheric pressure, so that the liquid level in the liquid containing box 204 descends, the liquid level in the air measurement box 209 ascends, the height of the magnetic floating bead 203 also ascends, and the magnetic field excited by the magnetic floating bead 203 also changes, so that the magnetic induction line is cut by the internal circuit of the magnetic field sensor 210, current is generated, and accurate numerical value of the liquid level ascending is obtained through the current and is transmitted to the control system. Because the cross-sectional area of the interior of gas box 209 is suitably constant, the control system used can calculate the volume of the liquid change, which is the volume of gas delivered by gas pump 207, because the liquid is difficult to compress. Meanwhile, a drying agent is placed in the drying bin 202, so that the gas passing through the liquid containing box 204 is kept dry, and moisture is prevented from being brought into the refueling oil tank 1.

The air inlet valve 211 one end fixedly connected with refuels oil tank 1, refuels oil tank 1 and includes oil tank box 109.
