Patent JP-H0216399-A (JP)
Title: Multistage pump
Inventor: TANAKA TEIJI
IPC: F04D29/44
Filed: 1987-07-09
Abstract: PURPOSE:To eliminate an influence by a reverse flow of fluid so as to improve performance in a low flow area by forming a side plate, opposed facing to an impeller in the upstream side, of the paired side plates larger in the outside diameter than that of a connection part between this side plate and a blade. CONSTITUTION:Two or more stages of impellers 2 are arranged in a casing 4. A spurn water blade 103, which guides fluid so as to be allowed to flow toward the internal periphery from the periphery, is provided between the impellers 2 in each stage. The spurn water blade 103 forms an outside diameter Di of its side plate 103a larger than the outside diameter Dr of a blade 103b. In operation of a pump in its low flow region, a flow (e) in the outer direction is inhibited by the side plate 103a, so that no influence is given to a flow (a). Thus enabling the total pump head to be increased in the low flow region, performance can be improved.

Abstract: PURPOSE:To apply effectively a magnet field to a liquid fuel by providing permanent magnets in the flowing passage for the liquid fuel inside a pressure atomizing nozzle. CONSTITUTION:A permanent magnet 7 such as a rare earth cobalt magnet etc. has a high magnetic flux density of 2,000 gauss or more and two permanent magnets 7 which are formed in cylindrical or spherical shape and arranged in a line are inserted into a magnet case 4. These magnets generate a magnetic field M and while the liquid fuel passes through a flowing passage 2 inside the mainbody 1 of a nozzle is flowing in the direction of the arrow as indicated, the fuel flows across the field M and is treated in a magnetic field. The liquid fuel, if it is hydrocarbon-based one, is changed into the fuel which has lower molecular weight than that of the one which is not treated in a magnetic field due to the phenomenon that a part of molecular bonding chains of carbon- hydrogen is cut off or the viscosity coefficient of the treated fuel is made slightly smaller than that of non-treated fuel and therefore, combustion efficiency is improved and also low soot burning is made possible.
