NON-ELECTRICAL TYPE FLUID PUMP

摘要

PURPOSE: A non-electrical type fluid pump is provided to deliver fluid without using electricity as driving power. CONSTITUTION: A fluid pump(1) comprises a tank(2); a cover(3); a shaft(5); and a heating member(6). The tank has a cylindrical body with one end open, an inlet(7) on a lower part of the body, an outlet(8) on an upper part of the body and a concave receiving part(9) formed on an inner surface facing the opening part. The cover has a concave receiving part(11) formed on an inner surface thereof and is detachably assembled to the opening part of the tank to open and close the opening part. The shaft has a spiral screw(4) formed on a lengthwise periphery thereof and protrusions(12) one both sides thereof inserted to and supported by the receiving parts of the tank and the cover. The heating member is installed on a lower part of the tank to apply heat to heat exchange medium supplied to the tank. The heating member heats the heat exchange medium supplied to the tank to raise air in the tank so that the rising air rubs against the screw to rotate the shaft to deliver the heat exchange medium. The heated heat exchange medium has volume thereof expanded to accelerate rotation of the screw.
