Abstract
Объемная роторная машина (ОРМ), у которой поршень, установленный в пазу ротора, совершает вращательные колебания, однако, оказалось, что он при этом, даже на больших оборотах ОРМ, не испытывает больших инерциальных нагрузок. Т.к. массы, распределенные вблизи линии (плоскости), которая в среднем положении поршня проходит через его ось вращения перпендикулярно оси вращения ротора, совершают эти колебания в значительной мере за счет действия центробежных сил, возникающих при вращении поршня вместе с ротором. Установка на поршень вблизи указанной линии (плоскости) дополнительных уплотняющих синхронизирующих элементов (УСЭ), тоже практически не увеличивает инерционную нагрузку на него, улучшая условия его взаимодействия (контакта и скольжения) с плоской поверхностью корпуса. Более того, существуют конфигурации ОРМ, в которых поршень перекрывает рабочую камеру и создает перепад давления в период своего нахождения вблизи крайних точек колебания, т.е. тогда, когда его скорость относительно ротора минимальна, а значит, минимальны потери на трение и износ. В результате получилась ОРМ с высокими удельными характеристиками (отношение мощности к размеру и весу, подачи к размеру), с потенциально большими ресурсом и надежностью, геометрически простыми рабочими поверхностями (плоскость по плоскости, сфера по сфере). Предполагается широкое использование ОРМ в многоступенчатых погружных насосах.The volumetric rotary machine (ORM), in which the piston installed in the rotor slot, makes rotational oscillations, however, it turned out that it does not experience large inertial loads, even at high speeds of the ORM. Because masses distributed near the line (plane), which in the middle position of the piston passes through its axis of rotation perpendicular to the axis of rotation of the rotor, make these oscillations largely due to the action of centrifugal forces arising from the rotation of the piston with the rotor. Installation on the piston near the specified line (plane) of additional sealing synchronizing elements (SSE) also practically does not increase the inertial load on it, improving the conditions for its interaction (contact and sliding) with the flat surface of the housing. Moreover, there are ORM configurations in which the piston overlaps the working chamber and creates a pressure drop during the period of its location near the extreme points of oscillation, i.e. when its speed relative to the rotor is minimal, which means that friction and wear losses are minimal. The result was an ORM with high specific characteristics (ratio of power to size and weight, feed to size), with potentially large resources and reliability, geometrically simple working surfaces (plane on a plane, sphere over a sphere). Expected widespread use of ORM in multistage submersible pumps.
