(54) СПОСОБ РЕГУЛИРОВАНИЯ ДАВЛЕНИЯ В КОЛЛЕКТОРАХ НАГНЕТАНИЯ КОМПРЕССОРНОЙ СТАНЦИИ(54) METHOD OF ADJUSTMENT OF PRESSURE IN THE COLLECTORS OF THE DISCHARGE COMPRESSOR STATION

Изобретение относитс к регулированию компрессоров с общим коллектором нагнетани .The invention relates to the regulation of compressors with a common discharge manifold.

Известен способ регулировани давлени в коллекторах нагнетани компрессорной станции путем поддерживани давлени на заданном уровне последовательным дросселированием в лини х всасывани и выпуском газа в атмосферу 1 .There is a method of controlling the pressure in the manifolds of the compressor station by maintaining the pressure at a predetermined level by sequential throttling in the suction lines and the release of gas into the atmosphere 1.

Однако указанный способ обладает недостаточной экономичностью.However, this method has insufficient efficiency.

Целью изобретени вл етс повышение экономичности компрессорной станции при работе на коллекторы высокого и низкого давлени .The aim of the invention is to increase the efficiency of the compressor station when working on high and low pressure collectors.

Указанна цель достигаетс тем, что давление в коллекторе низкого давлени дополнительно регулируют путем перепуска газа из коллектора высокого давлени , осуществл емого с помощью регул тора коллектора высокого давлени , срабатывающего по сигналам регул тора коллектора низкого давлени .This goal is achieved by the fact that the pressure in the low-pressure manifold is additionally regulated by bypassing the gas from the high-pressure manifold using the high-pressure manifold adjuster, triggered by the signals of the low-pressure manifold regulator.

Claims

in a way. In the initial position, the consumption of both collectors 1.16 is insignificant, the throttle flaps 7.22 are closed, the exhaust valve 12 is closed and the bypass valve 9 and the exhaust valve 24 are open. The suction conditions account devices 15 and 27 serve to change the value of the throttle valves cover 7 and 22 to the minimum permissible value in terms of surge safety, depending on the suction conditions and the value of the pressure maintained in the collectors 1 and 16. With an increase in the consumption of low and low pressure in the collector 16, the pressure in it is lower s, dates; snip 29 sends a signal to a pressure regulator 17 which moves the switchgear-inflammatory spool 19 upwards. This closes the drainage of the exhaust valve actuator oil 24, and it closes. With a further increase in consumption, a drain is opened about the precise oil of the throttle actuator drive 22 in the distribution spool 19, which leads to the opening of the shutter 22. With a further increase in consumption, the control spool 19, continuing upward, opens the drain of the throttle actuator flow oil 7 8 and the amount of bypass air. If in the initial position the consumption from the high-pressure collector increases, the pressure regulator 2, after processing the signal from the sensor 28, moves the distribution spool 4 upwards, the drainage oil of the drive oil of the overflow valve 9 opens and it closes. With a further increase in consumption in the distribution spool 4, the flow-through oil of the drive of the throttle valve 7 of the compressor 8 opens, which leads to the opening of the valve 7 and an increase in the output of the co-compressor. Thus, additional control of the pressure in the low-pressure manifold by bypassing the gas from the high-pressure manifold through the high-pressure manifold regulator connected to the low-pressure manifold adjuster increases the efficiency of the compressor station. Claims The method of pressure control in the discharge manifolds of the compressor station by maintaining the pressure at a predetermined level by sequential throttling in the suction lines and the release of gas into the atmosphere, characterized in that, in order to increase the efficiency of the compressor station when working on the high and low pressure collectors, the low pressure manifold is additionally regulated by bypassing the gas from the high pressure manifold, carried out with ps, by the power of the high the pressure triggered by the signals of the low pressure manifold control.
