Pumping apparatus utilizing difference between gravity and buoyancy
专利汇可以提供Pumping apparatus utilizing difference between gravity and buoyancy专利检索，专利查询，专利分析的服务。并且PURPOSE:To pump the sea water without causing public nuisance by employing a weight tank and a float and utilizing the function of gravity and buoyancy. CONSTITUTION:A pumping pipe 8a extending downward into a sea water pressurizing machine 10 supported on the bottom of sea B is provided on a base 2 arranged on the ocean. A weight tank 1 arranged above the surface of sea A and a float chamber 4 arranged below the surface of sea are integrated through a supporting member 3. The integrated member 1, 4 is guided movably up and down around the pumping pipe 8a. Then compressed air is fed into the float chamber 4 through a pump 21 or an accumulator 15 to remove the sea water. Thus to float said member 1, 4 through the buoyancy. Thereafter, a valve 23 is opened to discharge the compressed air into the atmosphere thus to lower through the gravity of the tank 1. Said up/down motions are repeated to function a piston 9 through a pushing member 8b. The sea water pressurizing machine 10 will deliver the sea water at the bottom of sea to the pumping pipe 8a by means of the piston 9.，下面是Pumping apparatus utilizing difference between gravity and buoyancy专利的具体信息内容。
