Abstract: PURPOSE: A regenerative pump for controlling the gap of an impeller is provided to easily control the gap between an impeller and the inner wall of a pump by attaching/detaching of a gap control member. CONSTITUTION: An impeller is rotatably installed in a housing. A fluid path is formed along the edge of the impeller so that fluid moves. An inlet and an outlet are respectively communicated with the fluid path at an interval so that fluid flows into or out. The housing comprises a groove, which is formed on the space between the inlet and the outlet. A gap control member(3) is coupled to the groove to prevent flow from flowing into the inlet or the outlet and controls the gap between the inner wall of the housing and the end of the impeller.

Abstract: PURPOSE: An apparatus and a method for removing the residual liquid cargo from a storage tank are provided to efficiently suck the residual liquid cargo by injecting compressed gas at high speed to form a vacuum. CONSTITUTION: An apparatus for removing the residual liquid cargo from a storage tank comprises a suction chamber(10), a compressed gas storage unit(20), an ejector(30), a 4-way valve(40), a settling tank(50), and a 3-way valve(60). The suction chamber sucks residual cargo(O) from a suction well(1) and temporarily stores it. The ejector injects compressed gas(G) at high speed to a vacuum and draws in the residual cargo with the vacuum and into the suction chamber. The 4-way valve selectively connects the suction chamber, the compressed gas storage unit, and the ejector. The settling tank stores and discharges the residual cargo. The 3-way valve selectively connects the compressed gas storage unit, the suction chamber, and the settling tank.

Abstract: A heat exchange pipe unit is provided to improve the heat exchange efficiency of a heat exchanging pipe by increasing the contact area of the heat exchanging pipe and the exhaust gas of the high temperature. The heat exchanging pipe comprises a pair of heat exchanging pipes. A pair of heat exchanging pipes comprises a plurality of spiral projections(121) and a gas path(122). A pair of heat exchanging pipes collects the heat from the exhaust gas of the high temperature passing through outside, and the exhaust gas passes along the spiral gas path formed at the outer circumference, in order to increase the contact area with the exhaust gas. The spiral projection of a first heat exchanging pipe among a pair of heat exchanging pipes is wound in the spiral shape of the right screw direction. The spiral projection of a second heat exchanging pipe among a pair of heat exchanging pipes is wound in the spiral shape of the left screw direction. The first and the second exchanging pipe are piled to the top and bottom direction.

Abstract: A wear prevention device for a gas foil bearing in a high-speed revolution axis system is provided to prevent abrasion of foils such as a top foil and a bumper foil by widening plural blade parts circumferentially using the centrifugal force of a collet. A wear prevention device for a gas foil bearing in a high-speed revolution axis system comprises a rotating shaft(20) having plural blade parts(41) formed at its one end, a collet(40), a sleeve(50), and a bearing housing(31). The collet widens plural blade parts circumferentially by the centrifugal force resulting from high speed rotation. The sleeve limits the displacement of the collet. The bearing housing includes an outer wheel(71) of a rolling bearing, and an inner wheel(72) including a bushing(60). The rolling bearing supports the rotating shaft by mounting the collet on the bushing in a stop of rotation or low speed rotation.
