Description

Известны гидравлические устройства дл  автоматического программного управлени  работой нескольких гидродвигателей с дроссельным регулированием. Однако коэффициент полезного действи  таких устройств недостаточно высок.Hydraulic devices are known for automatically programmatically controlling the operation of several hydraulic motors with throttle control. However, the efficiency of such devices is not high enough.

В описываемом устройстве дл  повышени  коэффициента полезного действи  применен питающий насос переменной производительности, работающий по заранее заданной программе в зависимости от величины максимальной нагрузки и потребного расхода рабочей жидкости всеми гидродвигател ми в каждый момент времени.In the described device, to increase the efficiency, a variable capacity feed pump is used, which operates according to a predetermined program, depending on the maximum load and the required flow rate of the working fluid by all hydraulic engines at each time point.

На чертеже изображена схема устройства.The drawing shows a diagram of the device.

Гидравлическое устройство дл  автоматического программного управлени  работой нескольких гидродвигателей состоит из питающего насоса / переменной производительности, приводимого электродвигателем 2, гидродвигателей 3 с регулирующими дроссел ми 4, считывающего механизма 5, преобразовател  6, дифференциального элемента 7, усилител  8с управл ющим элементом 9 и гидроусилителем 10 и предохранительного клапана 11.A hydraulic device for automatic software control of several hydraulic motors consists of a feed pump / variable output driven by an electric motor 2, hydraulic motors 3 with regulating throttles 4, a reading mechanism 5, a converter 6, a differential element 7, an amplifier 8c with a control element 9 and a hydraulic booster 10 and safety valve 11.

Механизм 5 считывает программу работы питающего насоса 1 с перфорированной ленты 12, на которой она записана, и подает соответствующие импульсы в преобразователь 6, на выходе которого по вл етс  напр жение, соответствующее максимальной нагрузке и потребному расходу рабочей жидкости всеми гидродвигател ми 3 в каждый момент времени. Это напр жение, пропорциональное углу поворота люльки 13 насоса /, измен ющего его производительность, поступает от преобразовател  6 на дифференциальный элемент 7, где сравниваетс  с напр жением, подаваемым датчиком 14 полол :ени  люльки 13. Алгебраическа  разность сравниваемых напр жений усиливаетс  в усилитеThe mechanism 5 reads the program of operation of the feed pump 1 from the perforated tape 12 on which it is recorded, and supplies the corresponding pulses to the converter 6, at the output of which a voltage appears corresponding to the maximum load and the required flow rate of the working fluid by all hydraulic motors 3 at each moment of time. This voltage, proportional to the angle of rotation of the pump cradle 13, which changes its performance, is supplied from converter 6 to differential element 7, where it compares with the voltage supplied by sensor 14 of the floor: cradle 13. The algebraic difference of the compared stresses is amplified in amplification
