Изобретение относитс к автоматическому регулированию и может быть использовано в приводах прецизионных станков и механизмов,This invention relates to automatic regulation and can be used in drives of precision machines and mechanisms.
Цель кзобрететли - расширение об- дасти применени и повьппение точнос- |ги устройст1за.The goal of the inventor is the expansion of the use and accuracy of the device.
Схема устройства показана на чер- .Diagram of the device is shown in black.
I Устройство содержит корпус 1 с Ьходной 2 и выходной 3 полост ми, ьазмещенный в корпусе 1 ротор 4, на поверхности которого выполнена дроссельна винтова канавка, соединенрасхода (скорости установившегос движени жидкости в дроссельной винтовой канавке) измен етс перепадI The device comprises a housing 1 with an input 2 and an output 3 cavities, a rotor 4 located in the housing 1, on the surface of which a throttle screw groove is made, is connected to a flow (the velocity of the steady motion of the fluid in the throttle screw groove) changes
давлени между входной и выходной полост ми и на выходе датчика 7 по вл етс сигнал, поступающий в блок 6 управлени , где сравниваетс с задающим сигналом. По сигналу рассогласовани the pressure between the input and output cavities and the output of the sensor 7 is the signal entering the control unit 6, where it is compared with the reference signal. By signal mismatch
блок управлени измен ет скорость вращени двигател 5 и св занног о с ним ротора 4, что приводит к восстановлению заданного расхода жидкости.The control unit changes the speed of rotation of the engine 5 and the rotor 4 connected with it, which leads to the restoration of the predetermined flow rate.
