(54) УСТРОПСТВОДЛЯ БАЛАНСИРОВКИ РОТОРОВ(54) DEVICE FOR BALANCING ROTORS

Изобретение относитс к балансировочной технике и.может.быть применено в общем машиностроении.The invention relates to a balancing technique and can be applied in general engineering.

Известно устройство дл балансировки роторов, содержащее источник дл подачи жидкости, распределительную емкость и балансировочные резервуары , соединенные с распределительной емкостью каналами. Жидкость из распределительной емкости поступает в балансировочные резервуары, компенсиру дисбаланс ClJ.A device for balancing rotors is known, which contains a source for supplying a liquid, a distribution capacitance and balancing tanks connected to the distribution capacitance by channels. The liquid from the distribution tank enters the balancing tanks, compensating for the imbalance ClJ.

Недостатком устройства вл етс возможность только статической балансировки .The drawback of the device is the possibility of only static balancing.

Наиболее близким к изобретению по технической сущности вл етс устройство дл статической балансировки роторов, содержащее располагаемые соосно с ротором по обе стороны от его центра т жести в двух плоскост х коррекции источники дл подачи жидкости , св занные с ними распределительные емкости и балансировочные резервуары, расположенные по окружности ротора в тех же плоскост х коррекции, трубопроводы, входное отверстие котоЕЯЛх смещено относительно выходных отверстий на 90, соедин ющие в каждой плоскости коррекцииThe closest to the invention to the technical essence is a device for static balancing of rotors, containing sources for liquid supply located coaxially with the rotor on both sides of its center of gravity in two correction planes, associated distribution tanks and balancing tanks located along the circumference of the rotor in the same correction planes, pipelines, the inlet opening which is shifted relative to the outlet openings by 90, connecting in each correction plane

Недостатком устройства вл етс возможность балансировки роторов только на сверхкритических оборотах.The disadvantage of the device is the possibility of balancing rotors only at supercritical revolutions.

Целью изобретени вл етс обеспечение динамической балансировки роторов на докритических и сверхкритических оборотах с автоматичес10 ким переходом с-одного режима на другой.The aim of the invention is to provide dynamic balancing of rotors at subcritical and supercritical revolutions with automatic switching from one mode to another.

Поставленна цель достигаетс тем, что устройство-дП балансировки роторов снабжено двум дополнительными распределительными емкост ми, сообщенными с основньми распределительными емкост ми посредством подпружиненных обратных клапанов, и дополнительными трубопроводами, св 20 зывающими балансировочные резервуары в одной плоскости коррекции с дополнительными резервуарами в другой плоскости коррекции.This goal is achieved by the fact that the device-rotor balancing device is equipped with two additional distribution tanks communicated with main distribution tanks by means of spring-loaded non-return valves, and additional pipelines connecting the balancing tanks in one correction plane with additional tanks in another correction plane.

Claims

A device for balancing rotors contains distribution tanks 1 installed coaxially with rotor 2 on both sides of its center of T tinsel, sources 3 for supplying liquid KOCTHf feeding the liquid into distribution tanks 1 through the central opening 4, balancing tanks 5, pipelines 6 connecting the radial direction offset by-90 tanks 5 with distribution tanks 1 in each correction plane, additional distribution-capacitances 7 connected to distribution tanks 1 by means of sub-strings of the non-return valves 8, and to the balancing tanks 5 with the help of additional pipelines 9, and the distribution tanks 1 of one correction plane are connected in the radial direction to the balancing tanks 5 of the other correction plane. The nozzles 10 of the pipelines .6 are inserted into the distribution tank 1, and the entrances to them overlap the spring-loaded spring valves 8. The balancing tanks 5 by the fitting 11 and the nozzle 12 are in communication with the atmosphere. The diameter of the additional distribution tanks 7 is larger than the diagonal of the main distribution tanks 1, and the inlets to the pipes 13 of the pipelines 9 are radially farther from the axis of the device than the valves 8. The device operates as follows. The device is rotated. From sources 3 for supplying liquid through the opening 4, the liquid is supplied to distribution tanks 1 in which it is distributed depending on the imbalance. Moreover, its part through the pipes 10 and pipelines 6, falls into the balancing tanks 5 in each plane of correction, compensating for the imbalance. With an increase in revolutions, the inlets to the nozzles 10 are exposed. Under the action of pressure created by centrifugal forces and a liquid column, valves 8 are opened, and the liquid bursts into the distribution tank, in which it is distributed depending on the imbalance. Valves 8 are set to open immediately after the transition from subcritical to supercritical turns. Liquid distributed in the tank 7, depending on the imbalance, floods the inlets to the nozzles 13 and enters the balancing tanks 5 through pipelines 9, eliminating the imbalance at supercritical revolutions. At the same time, the fluid from the balancing reservoirs 5 is discharged through the nozzles 12 to the atmosphere. The air from the balancing reservoirs 5 is displaced by the fluid through the nozzles 11 to the atmosphere. Connecting to the balancing capacity additional capacity, communicating with the main distribution capacity through spring-loaded check valves, and the message of additional distribution capacity of one correction plane in the radial direction with balancing tanks of another correction plane, allows for dynamic balancing of the balanced node at subcritical and supercritical turns with automatic transition from one mode to another. An invention of a device for balancing rotors, containing liquid supply sources located on both sides of the center of gravity of the rotor in its correction planes, associated distribution tanks and balancing tanks, as well as pipelines whose inlet is shrunk relative to the outlet by 90, connecting distribution tanks and balancing tanks in each plane of correction, which is, so as to ensure dynamic balancing of the rotors on the dock iti-; with automatic switching from one mode to another, it is equipped with two additional distribution tanks, communicated with the main distribution tanks by means of spring-loaded non-return valves, and additional pipelines connecting the balancing tanks in one correction plane with additional tanks in the other plane correction.
