<p>PURPOSE:To aim at simplifying the installation, inspection and maintenance of a pressurizing device, by removably connecting, with a coupling seat formed in the bottom peripheral wall of an intake chamber, an underwater pump having its axial direction extending in substantial parallel with the bottom of the intake chamber and a pressure tank arranged outside of and spaced from the intake chamber. CONSTITUTION:A plurality of coupling seats 1c are integrally formed in the peripheral wall on the bottom side 1a of an intake chamber 1, and of the coupling seats 1c, the one coupling seat 1a which is communicted with a water passage 1f is removably and water-tightly connected with an underwater electrical pump 7 arranged in the bottom 1a of the intake chamber 1 and having its axial direction extending in substantial parallel with the bottom 1a and a pressure tank 12 arranged adjacently to and outside of the intake chamber 1 through a hollow coupling member 13 communicated with the water passage 1f. With this arrangement, the installation, inspection and maintenance of the pressurizing device, and the intake chamber 1 and a lid 2 are made light-weighted since the weight load of the pressure tank 12 is not at all applied to the intake chamber 1, thereby the pressurizing device may be manufactured at a low cost. Further, the inspection of the underwater pump 7 may be simply made.</p> |
