Description
Описываемое изобретение относитс к области ту-рби;шых рабочих колес дл турбобуров, примен емых дл бурени скважий.The described invention relates to the field of turbo-tubes, turbine drills used for drilling wells.
Известные конструкции забойных двигателей-турбобуров характеризуютс тем, что ирофил1и лопаток серийных, машин имеют цилиндрическую форму как у статора, так и у ротора, что вл етс причиной СИЛЬНОГО искажени формы междулопаточных каналов, ушир ющихс в вершииу лонаток. Така снижает к. п. д. ступени турбины.The known designs of downhole motor-turbo-drills are characterized by the fact that irofilia and blades are serial, the machines have a cylindrical shape both at the stator and at the rotor, which is the reason for the STRONG distortion of the shape of the inter-blade channels broadening at the top of the ribs. This reduces the efficiency of the turbine stage.
Описываемое изобретение устран ет этот недостаток.The described invention eliminates this disadvantage.
На чертеже изображен профиль предлагаемых лопаток турбины.The drawing shows the profile of the proposed turbine blades.
Лопатки / колеса турбины выполнены в виде дуговых отрезков кольца 2, по отношению к радиальному сечению которого дуговые отрезки имеют вогнутый по расчету желобообразный профиль 3, что обеспечивает в межлопаточных каналах посто нсиво осевой составл юш,ей скорости потока вдоль лопаток.The blades / turbine wheels are made in the form of arc segments of the ring 2, with respect to the radial section of which the arc segments have a concave-shaped trough-like profile 3, which ensures a constant axial component in the interscapular channels and its flow velocity along the blades.
Предмет изобретени Subject invention
Турбинное рабочее колесо дл турбобура, отличаюш,еес тем, что, с целью обеспечени а межлопаточных каналах посто нства осевой соста1вл юш,ей скорости потока вдоль лопаток, последние выполнены в виде дуговых отрезков желобообразного кольца.The turbine impeller for a turbodrill is distinguished by the fact that, in order to ensure that the interscapular channels are of axial stability, it has a flow velocity along the blades, the latter are made in the form of arc segments of a grooved ring.
