摘要： PURPOSE: To facilitate the detection of runout and correct properly as required by supporting a lower impeller shaft with a provisional bearing mechanism and by revolving it at a low speed and by detecting the verticality of a main shaft.
CONSTITUTION: A lower impeller shaft 1 is supported with a provisional bearing mechanism 24. The verticality as well as the leveling are indipendently adjusted, allowing the impeller to revolve at a low speed. Then, the verticality of an upper impeller shaft 2 and the leveling of the upper end surface are detected by performing a low speed revolution accompanied by the motion of the lower impeller shaft 1 whenever connected. With this construction, the runout of the verticality of each axial line as well as the leveling of the upper end connection faces can be detected on the way to installation process for the impeller shafts 1 and 2 respectively. Therefore, the verticality of the main shaft can be easily detected and can be properly corrected whenever required.

摘要翻译：目的：通过用临时轴承机构支撑下叶轮轴，并以低速旋转并通过检测主轴的垂直度，便于检测跳动并正确正确。构成：下部叶轮轴1由临时轴承机构24支撑。垂直度和平整度被独立调节，允许叶轮以低速旋转。然后，连接时，通过执行伴随下叶轮轴1的运动的低速旋转来检测上叶轮轴2的垂直度和上端面的调平。通过这种结构，可以分别在叶轮轴1和2的安装过程中检测到各轴线的垂直度的跳动以及上端连接面的调平。因此，可以容易地检测主轴的垂直度，并且可以在需要时进行适当的校正。

摘要： PURPOSE:To prevent a water leak from an alignment face in a gasket having a crossing part and mounted to the alignment face of a flange, by forming the gasket in a different shape and dimension for sections in a T-shaped crossing part of the gasket and in a gasket groove. CONSTITUTION:In a gasket mounted to mated flanges of casings, upper and lower covers and the like in reversible pump-turbines, a gasket groove 10 at one side of the groove crossing in a mated flange face of parts contacted to a water flow line is formed in a deep V-shape and a gasket groove 12 at the other side in a shallow U-shape. While the gasket groove 12 is constructed such that it is smoothly combined at a portion 13 to become a V-shaped groove with the separation from a crossing part. Then equipped gaskets 6, 7, 14, 15 are changed correspondingly to sectional areas of the gasket grooves 10-13. While the gasket groove 12 is formed shallower than the gasket groove 10 to H>h decreasing deformation of the gasket in a crossing part 9.

摘要： PURPOSE:To improve operatability, by incorporating a bottom ring into a pump- turbine proper as one body of a ring form in case of a vertical shaft type pump- turbine. CONSTITUTION:Hoisting a guide vane 12, it is inserted into a bottom ring 10 from topside of the ring 10 and set said vane 12 to the latter with a fixing ring 58. Then, a guide vane lever 26 is coupled with the guide vane 12 and the bottom ring is turned upside down. And, the bottom ring 10 is secured to the top of a truck 54 via a block 56. Afterward, the guide vane lever 26 is inserted into the guide vane 12 and a thrust ring 30 is fixed to the bottom ring 10. And, coupling the guide vane lever 26 with the guide vane 12, rings 38 are set to top and bottom of a flange part 26b each in addition. The bottom ring 10 is taken in a draft chamber 50 and connected to the circumference of a main shaft 14 of the pump-turbine in an annular form.

摘要： PURPOSE:To increase reliability of the installation work in such a way that the members underneath the pump water turbine are built in the outer return guide beforehand, as an assembly which is installed as a foundation, and only those members in the upper part of the outer return guide are assembled on the basis of the outer return guide. CONSTITUTION:An outer return guide 26 is inverted and provisionally installed beforehand, and a guide vane operating mechanism consisting of a guide vane 30, a lower cover 28 and a guide vane lever 64, etc. is assembled in composition through its top face, namely from the side of lower cover attaching surface 52. Then, installation is carried on in the procedure that the outer return guide 26 of a built-in structure is lifted, inverted and fixed to the foundation, and the lower cover 22 of the upper runner 12, the casing 16, etc. are successively piled up, assembled and installed on the basis of this installed outer return guide 26. Thus, since there is no need of complicated jack-up operation, working efficiency is remarkably improved, and in addition to it, because it becomes a piling up process, not alone the safety is improved, but also level adjustment of the pump water turbine itself can be soundly processed, so that installation of a pump water turbine with high reliability can be achieved.

摘要： PURPOSE:To facilitate a disassembling and assembling by laying a looplike railing on a floor in an operation mechanism room and further providing movable four divided circular arc shaped trucks on this looplike railing. CONSTITUTION:A looplike railing 30 is laid directly underneath of a lower cover 22 around a suction piping 18 in a operation mechanism room 26, and four movable divided circular arc shaped trucks 32 are provided on this looplike railing 30. By this mechanism, notwithstanding the presence of a main shaft 20 scarecely subjected to disassembling an assembling thereof becomes practicable by temporary disassembling due to its integrated loop construction, hence an assmebling around the main shaft 20 becomes practicable especially at a time of an assembling of the water wheel leading to an easy disassembling and assmebling thereof.
