Description
тановки лопастей в виде вертикального вала 7 00 сменными дисками. Опорные колонны 3 снабжены радиально смещающимис колодками 8 с помощью винтов 9. На опорных втулках 4 колонн 3 уложена сменна кольцева площадка 10.Blades in the form of a vertical shaft 7 00 interchangeable discs. The supporting columns 3 are provided with radially displaced blocks 8 with screws 9. A replaceable annular platform 10 is mounted on the supporting sleeves of 4 columns 3.
Узел установки лопастей выполнен в виде двух верхнего к нижнего сменных дисков II и 12, смонтированных на центральном вертикальном валу 7, при этом верхний сменный диск 11 имеет возможность перемещени по вертикальному валу 7 и фиксируетс винтами 13.The blade mounting unit is made in the form of two upper to lower removable disks II and 12 mounted on a central vertical shaft 7, while the upper removable disk 11 has the ability to move along the vertical shaft 7 and is fixed by screws 13.
Сменные диски 11 и 12 и кольцева площадка 10 снабжены винтовыми упорами 14, 15 и 16 по шагу установки лопастей 17 в рабочем колесе. При этом к лопаст м приварены технологические планки 18.Replaceable discs 11 and 12 and the ring pad 10 are equipped with screw stops 14, 15 and 16 in accordance with the installation step of the blades 17 in the impeller. At the same time technological strips 18 are welded to the blade.
На верхнем торце центрального вала смонтирован консольный подъемник 19 и рейсмус 20, а на втулках 4 колонн 3 смонтированы подмостки 21, имеющие возможность вертикального перемещени совместно с винтовыми упорами 5 и кольцевой площадкой 10.A cantilever lift 19 and gauge 20 are mounted on the upper end of the central shaft, and a scaffold 21 is mounted on the sleeves 4 of the columns 3, having the possibility of vertical movement together with the screw stops 5 and the annular platform 10.
Стенд работает следующим образом.The stand works as follows.
В зависимости от типоразмера рабочего колеса гидротурбины на центральный вал 7 надеваютс сменные диски 11 н 12 соответствующих размеров, а на колонны укладываетс кольцева- площадка 10. Нижний обод 2 укладываетс на основание 1, вывер етс его соосность и зажимаетс колодками 8 с помощью винтов 9.Depending on the size of the impeller of the hydraulic turbine, removable disks 11 and 12 of the respective sizes are put on the central shaft 7, and the ring-section 10 is placed on the columns.
Лопасти 17 мостовым краном и с помощью консольного подъемника 19 устанавливаютс на нижний обод, фиксируютс винтовыми упорами 14, 15 и 16 через технологические планки 18, в которых выполнены технологические центры. В технологических центрах производитс механическа обработка лопастей 17, поэтому при зажиме они зан ть оптимальное положение без дополнительной выверки .The blades 17 are mounted by a bridge crane and mounted on the lower rim with the help of a cantilever lift 19, fixed by screw stops 14, 15 and 16 through technological strips 18 in which technological centers are made. In the technology centers, the blades 17 are mechanically machined; therefore, when clamping, they occupy the optimum position without additional alignment.
После установки всех лопастей верхний обод 6 укладываетс на кольцевую площадку 10, вывер етс его соосность с помощью рейсмуса 20 и зажимаетс винтовыми упорами 5.After all the blades have been installed, the upper rim 6 is laid on the annular platform 10, its alignment is verified with the help of gauge 20 and clamped by screw stops 5.
После сборки н контрол производитс прихватка деталей рабочего колеса иAfter assembly n control, tacking of the impeller parts and
сварка. Подмостки 21 предназначены дл удобства обслуживани стенда.welding. Stage 21 is designed for ease of maintenance of the stand.
Стенд позвол ет производить механизированную сборку различных типоразмеров рабочих колес радиально-осевых гидротурбин с высокой степенью точности сборки при значительном снижении трудоем-кости сборочных работ.The stand allows mechanized assembly of various sizes of impellers of radial-axial hydraulic turbines with a high degree of assembly accuracy with a significant reduction in labor-intensive assembly work.
