Claims (4)

1. Способ регулирования давления текучей среды, которую при помощи генератора давления, приводимого в действие от электродвигателя, перемещают в имеющей, по меньшей мере, одного потребителя системе труб, отличающийся тем, что число оборотов двигателя, предназначенного для регулирования давления (Р) в системе (1) труб, регулируют регулятором (9), в соответствии с, по меньшей мере, одной задающей давление текучей среды в системе труб (1) в зависимости от расхода протекающей текучей среды или, соответственно, от скорости (S) потока этой среды регулировочной характеристикой (R), которая между заданным минимумом и заданным максимумом давления проходит таким образом, равномерно изгибаясь, что в направлении возрастающего давления (Р) она лежит выше прямой (G), соединяющей точки минимального давления (Р1) и максимального давления (Р2), и в средней области между обоими точками (Р1, Р2) имеет максимальное удаление от этой прямой, на регулятор (9) в качестве действительного значения постоянно подают пропорциональную количеству протекающей текучей среды или, соответственно, скорости (S) ее потока электрическую величину и при отклонении действительного значения от заданного соответственно регулировочной характеристике (R) номинального значения давления (Р) число оборотов двигателя регулируют с целью компенсации отклонения.1. A method of controlling the pressure of a fluid, which, using a pressure generator driven by an electric motor, is moved in a pipe system having at least one consumer, characterized in that the engine speed for controlling the pressure (P) in the system (1) the pipes are regulated by the regulator (9), in accordance with at least one pressure setting fluid in the pipe system (1) depending on the flow rate of the flowing fluid or, accordingly, on the flow rate (S) of this medium, leveling characteristic (R), which passes between a given minimum and a given maximum pressure in such a way, uniformly bending that in the direction of increasing pressure (P) it lies above a straight line (G) connecting the points of minimum pressure (P1) and maximum pressure (P2) , and in the middle region between both points (P1, P2) has a maximum distance from this straight line, the regulator (9) is constantly supplied with the actual value proportionally to the amount of flowing fluid or, accordingly, the speed (S) of its electric flow The electric value and when the actual value deviates from the nominal pressure value (R) set accordingly to the control characteristic (R), the engine speed is adjusted to compensate for the deviation. 2. Способ по п.1, отличающийся тем, что регулятору (9) в зависимости от гидравлического сопротивления различных систем труб устанавливают различные регулировочные характеристики (R). 2. The method according to claim 1, characterized in that the regulator (9), depending on the hydraulic resistance of various pipe systems, sets various control characteristics (R). 3. Способ по п.1 или 2, отличающийся тем, что двигатель при недорасходе соответствующего минимальному давлению (Р1) количества протекающей текучей среды отключается, а при возрастании ее расхода вновь автоматически включается. 3. The method according to claim 1 or 2, characterized in that the engine, with an underconsumption corresponding to the minimum pressure (P1), of the amount of flowing fluid is turned off, and when its flow rate increases, it turns on again automatically. 4. Способ по любому из пп.1 - 3, отличающийся тем, что давление в системе (1) труб постоянно измеряют и результаты измерений подают на регулятор (9). 4. The method according to any one of claims 1 to 3, characterized in that the pressure in the pipe system (1) is constantly measured and the measurement results are fed to the regulator (9).
