Description
Изобретение относитс к области турбостроенн н может быть использовано, например , п паровых тзфбинах.The invention relates to the field of turbine construction. For example, steam turbines can be used.
По основному авт. св. Х9 522331 известны рабочие колеса турбомаи ины, содержащне лоиатки нижнего руса с межъ русными иолками и укрепленные на последних лопатки верхнего руса, причем лопаткн нижнего руса выполнены составными из продольных элементов , каждый из которых соединен с одной из iipHMbiKaiOHUix друг к другу нолок, а кажда иолка укреплена по крайней мере на двух элементах cf седних лопаток.According to the main author. St. X9 522331 known are the impellers of the turbomaine containing loiatki of the lower rus with interleaved ichols and reinforced on the last blades of the upper rus, the blades of the lower rus being made of composite longitudinal elements, each of which is connected to one of the other with one of the iipHMbiKaiOHUix to each other. strengthened on at least two elements cf of the middle blades.
Однако в таких рабочих колесах элементы лоиатки нижнего руса расиоложены с образованнем оби1его аэродинамического профил , что св заио с трудоемкостью изготовлени .However, in such impellers, the elements of the lower russia loiaty are rationalized with the formation of a large aerodynamic profile, which is due to the complexity of manufacturing.
Целью изобретен1 вл етс снижение трудоемкости изготовлени .The purpose of the invention is to reduce the labor intensity of manufacture.
Дл этого в предлагаемом рабочем колесе элементы лоиаток нижнего руса расноложены в И1ахматном пор дке.To do this, in the proposed impeller, the elements of the lower russia rifles are laid down in an imatite order.
На фиг. 1 пзображено предложенное рабочее колесо (частично); на фиг. 2 - разрез но А-А (ралверткп).FIG. 1 shows the proposed impeller (partially); in fig. 2 - section A-A (ralvertkp).
Рабочее колесо содержит рабочие .чоиатки верхнего 1 и нижнего 2 русов, тазделенные межъ русной нерегородкой 3. составленной нз полок.The impeller contains the working workers of the upper 1 and lower 2 Rus, which are interrupted by the intersite subunit 3. made up from the shelves.
Лопатка ннжнего руса выполнена нз продольных элементов, например, двух: входного 4 н выходного 5 (фнг. 2). которые смен1,ены в окружном ианравлечни др.уг относнтельно друга.The blade of the Russian rail is made of longitudinal elements, for example, two: input 4 n output 5 (fng. 2). which are c1, ena in the district and ants in another district relative to each other.
Элементы лопаток нижнего Я|)уса расиоложены в шахматном пор дке н образуют два р да межлопаточных каналов.The elements of the blades of the lower I |) are located in a checkerboard pattern and form two rows of interscapular canals.
