| 摘要 | A WELL SYSTEM WHICH INCLUDES A WATER STORAGE TANK, A WELL CASING EXTENDING THROUGH THE TANK AND INTO THE GROUND, A PUMP IN THE LOWER CASING END AND A WATER SUPPLY DROP PIPE BETWEEN THE PUMP AND TANK. THE CASING IS DIVIDED INTO SEVERAL PARTS BY A COUPLING. A PAIR OF PACKER BODIES ARE HUNG WITHIN THE CASING WITH THE COUPLING THEREBETWEEN. THE PACKER BODIES INCLUDE SUBSTANTIALLY IDENTICAL CORES WITH EACH CORE BEING DIVIDED INTO COMPLEMENTARY ADJACENT PASSAGES BY AN S-SHAPED WALL. WATER AND ELECTRICAL CONDUIT PASS THROUGH THE CORES, AND THE CONDUIT ALSO PASSES THROUGH THE TUBULAR CONNECTOR EXTENDING BETWEEN THE BODIES. THE PACKER BODIES ARE SEALED TO THE CASING WALL TO FORM A CENTRAL CHAMBER SO THAT WATER WITHIN THE CHAMBER PRESSURIZES THE INSIDE OF THE COUPLING. THE SEAL ON THE LOWER PACKER BODY IS A GENERALLY CUP-SHAPED RING. D R A W I N G |
