(Fig.Z / l)
На патрубках 6, 7, 12, 13, 27 и 28, а также на трубках 23 и 25 могут быть установлены дросселя, например регулируемые дросселя, для регулировки скорости нагнетания среды и скорости движения поршня 2. Учитывая стандартность этих устройств они на чертежах не показаны.On the nozzles 6, 7, 12, 13, 27 and 28, as well as on the tubes 23 and 25, throttles, for example adjustable throttles, can be installed to adjust the speed of the medium and the speed of the piston 2. Given the standard nature of these devices, they are not shown in the drawings .
Мйкронагнетательные устройства 4, 10 и 26, включая их привода 5, 11 и 29 являются преобразователями сигнала идущего с регулирующего устройства, например преобразователем электрического сигнала в пневматический или гидравлический сигнал.Micropressor devices 4, 10 and 26, including their actuators 5, 11 and 29, are signal converters coming from a control device, for example, an electric signal to pneumatic or hydraulic signal.
Устройство работает следующим образом:The device operates as follows:
Электрический сигнал с регулирующего устройства, например «бoлыпe», по электропроводу 19 поступает на электропривод 11, который воздействует на микронагнетательное устройство 10 начинающее нагнетать газообразную среду, например воздух, или жидкую среду, например воду или масло, в цилиндр 1, например на поршень 2, который начинает двигаться в левую сторону, одновременно этот сигнал поступает на электрический исполнительный механизм 9 открывающий клапан 8, подсоединённый через патрубок 7 к противоположному входу цилиндра 1, в данный момент выполняющий функции выхода, по отношению к входу через который нагнетается среда, стравливая эту среду из под поршня 2 исключая или уменьшая величину противодавления этой среды под поршнем 2. Совершенно аналогичный процесс происходит и при поступлении сигнала «мe- ныпe» по электропроводам 21 на электропривод 5 и на электрический исполнительный механизм 15, в этом случае микронагнеиаиельное устройство 4 начинает нагнетать среду под поршень 2, а клапан 14 начинает стравливать её над этим поршнем изключая противодавление этой среды, и поршень 2 начинает двигаться в право. Если управляющий сигнал, например «+», подаётся раздельно по электропроводам 19 или 21, в зависимости от отклонения заданного технологического параметра, то на электропривод 11 и электрический исполнительный механизм 9 соединённых паралельно, то на электропривод 4 и электрический исполнительный механизм 15 соединённых паралельно, а общий, опорный, сигнал, например «-», может подаваться постоянно на электропривода 5 и 11, электрические исполнительные механизмы 9 и 15 одновременно.
При использовании пневматического или гидравлического исполнительного механизма 22 или 24, управляющий сигнал, например «+», с регулирующего устройства подаётся только на электропривод 5 или на электропривод 11, с постоянном «-», которые при работе нагнетают среду в цилиндр 1, под поршень 2 или на поршень 2, и по трубке 23 или по трубке 25, на исполнительные механизмы 22 или 24, открывая стравливающие клапана 8 или 14, точка стравливания которых из цилиндра 1 расположена с противоположной стороны точке нагнетания в цилиндр 1 по отношению к поршню 2, тем самым исключается или уменьшается противодавление среды мешающее продвижению поршня 2.An electric signal from a regulating device, for example, “bolyp”, is fed through an electric wire 19 to an electric actuator 11, which acts on a micropressor 10 and starts to pump a gaseous medium, such as air, or a liquid medium, such as water or oil, into a cylinder 1, for example, a piston 2 , which begins to move to the left side, at the same time this signal is fed to the electric actuator 9 opening valve 8, connected through a pipe 7 to the opposite input of the cylinder 1, at the moment which increases the function of the output, with respect to the input through which the medium is pumped, bleeding this medium out from under the piston 2, eliminating or decreasing the back pressure of this medium under the piston 2. A completely similar process occurs when a “signal” occurs via electric wires 21 to electric drive 5 and to the electric actuator 15, in this case the micronagnet device 4 starts to pump the medium under the piston 2, and the valve 14 starts to bleed it above this piston, turning off the back pressure of this medium, and the piston 2 starts a move to the right. If a control signal, for example, “+”, is supplied separately via wires 19 or 21, depending on the deviation of a given technological parameter, then to an electric actuator 11 and an electric actuator 9 connected in parallel, then to an electric actuator 4 and an electric actuator 15 connected in parallel, and a common reference signal, for example, “-”, can be supplied continuously to electric drives 5 and 11, electric actuators 9 and 15 simultaneously. When using a pneumatic or hydraulic actuator 22 or 24, a control signal, for example “+”, from the control device is supplied only to the electric drive 5 or to the electric drive 11, with a constant “-”, which during operation pump the medium into cylinder 1, under the piston 2 or on the piston 2, and on the tube 23 or on the tube 25, on the actuators 22 or 24, opening the bleed valve 8 or 14, the bleed point of which from the cylinder 1 is located on the opposite side of the discharge point into the cylinder 1 with respect to the piston 2, from At the same time, counterpressure of the medium interfering with the advancement of the piston 2 is eliminated or reduced.
При использовании реверсивного микронагнетательного устройства 26, управляющие сигналы, например «+», с регулирующего устройства подаются через электропровод 19 или электропровод 21 на его реверсивный электропривод 29, при постоянной подаче «-», который управляет направлением нагнетания микронагнетательного устройства 26, нагнетающего среду на поршень 2 или под него по патрубкам 27 или 28, одновременно откачивая его из точки цилиндра 1 противоположной точке нагнетания в цилиндр 1 по отношению к поршню 2, тем самым исключается или уменьшается противодавление среды мешающее продвижению поршня 2. Таким образом достаточно, по меньшей мере, одного микронагнетательного устройства для работы заявленного привода.
When using a reversible micropressure device 26, control signals, for example, “+”, from the control device are fed through an electric wire 19 or an electric wire 21 to its reversible electric drive 29, with a constant supply of “-”, which controls the direction of discharge of the micropressive device 26, which pumps the medium onto the piston 2 or under it through pipes 27 or 28, while simultaneously pumping it from the point of cylinder 1 to the opposite injection point into cylinder 1 with respect to piston 2, thereby eliminating or decreasing otivavlenie environment interfering with the promotion of the piston 2. Thus, at least one micropressure device is sufficient for the operation of the claimed drive.
