Abstract

PURPOSE: To prevent explosion regardless of the level of stored liquid by applying sealing liquid around an under-liquid pump.
CONSTITUTION: Inside a tank 9 set inside a concrete body of an under-ground tank, a supporting pipe 10 penetrates its roof down to its floor; an under-liquid pump 8 is fixed liquid-tightly with appropriate seal to a suction opening 17 at the bottom of an airtight cylindrical case 16 moving vertically; water 20 is filled in the airtight cylindrical case 16 in advance and a discharge pipe 11 penetrates the inside of the supporting pipe through seal 19. Under this structure, the stored liquid 14 in the tank 9 is sucked through honeycomb slit 20 and a filter 13 into the under- liquid pump 8 by the operation of a motor 12 to be dishcarged from a discharge pipe 11. If the stored liquid 14, in this process, decreases to lower than the critical level L1 and is discharged till the danger level L2 so that the under liquid pump 8 may be exposed to the evaporated gas 15, the water 20 prevents the explosion of the under-liquid pump 8.
