PURPOSE:To reduce the number of facilities and jig, tools for fabrication and improve the efficiency of fabrication and assembly work by fixing the bending radius of a semicircular barrel plate for an oval tank and adjusting the length of a side plate on a straight-line part. CONSTITUTION:The width W of a tank is decided by the content of winding 6, etc. The bending radius Ro of semicircular barrel plate 1B is fixed and the length l of a side plate 1A on a straight-line part is adjusted so that a tank is fabricated. The fixed bending radius Ro of the barrel plate is caused to coincide with the maximum shape of an oval tank. The radius of the mounting part of various parts such as bushing pockets 4, 5, etc. to be installed on the semicircular barrel plate 1B is fixed at Ro. Thus standardization for fabrication is feasibe and the efficiency of part fabrication and assembly work can be improved significantly. |
