As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.
The offshore platform reciprocating compressor stepless speed regulating device based on the adjustable gas valve provided by the utility model closes the gas valve of the compressor after delaying the partial stroke of the operation of the compressor. An additional actuating mechanism is connected to the compressor, the actuating mechanism props against an air inlet valve of the compressor through high-pressure hydraulic oil in a hydraulic oil station, and the actuating mechanism does not act in the air suction process of the compressor; in the compression and exhaust process, the control system transmits a signal to the actuating mechanism, the actuating mechanism always keeps forcing the air inlet valve of the compressor to open before receiving the signal of the control system, so that redundant gas flows back into the air inlet cavity or pipeline of the compressor and does not participate in compression, after the control mechanism transmits the signal to the actuating mechanism, the actuating mechanism does not act on the air inlet valve of the compressor any more, the air inlet valve of the compressor is closed, the compressor only compresses the gas quantity left in the cylinder, and the gas quantity of the reciprocating compressor is adjusted through the process. The quantity of the compressed gas of the compressor can be effectively adjusted, so that stepless speed regulation of the compressor is realized.
In one embodiment of the present invention, as shown in fig. 1, there is provided an offshore platform reciprocating compressor stepless speed regulating device based on an adjustable gas valve, comprising:
the compressor 1 is arranged on an offshore wellhead gas pipeline;
the control end of the actuating mechanism 2 is connected with the air inlet valve of the compressor 1 and is used for controlling the air suction and air intake working state of the compressor 1;
the output end of the hydraulic oil station 3 is connected with the actuating mechanism 2, and hydraulic oil is provided for the actuating mechanism 2 through a hydraulic oil pipeline;
and the output end of the control mechanism 4 is respectively connected with the actuating mechanism 2 and the hydraulic oil station 3 and is used for transmitting control signals to the actuating mechanism 2 and the hydraulic oil station 3 so as to control the working states of the actuating mechanism 2 and the hydraulic oil station 3.
In the above embodiment, as shown in fig. 2, the stepless speed regulating device further includes a temperature sensor, a pressure sensor and a flow sensor. Temperature sensors, pressure sensors and flow sensors are provided on the pipes at the inlet and outlet of the compressor 1, and the detected inlet and outlet temperature signals T, pressure signals P and flow signals F are transmitted into a UCP (unit control panel) of the compressor unit.
When in use, the UCP processes various received signals and transmits control instructions to the control mechanism 4.
In the above embodiment, the control mechanism 4 is connected to the actuator 2 and the hydraulic oil station 3 by cables, and sends control signals to the actuator 2 and the hydraulic oil station 3.
In the above embodiment, the actuator 2 includes:
the electromagnetic valve 5 is connected with the control mechanism 4 and receives the control signal transmitted by the control mechanism 4; and is connected with the hydraulic oil station 3 to control the output flow of the hydraulic oil station 3;
and the bottom of a piston cylinder of the piston mechanism 6 is connected with the hydraulic oil station 3 through an electromagnetic valve 5, and the end part of the piston rod is in contact connection with an air inlet valve of the compressor 1 so as to control the operation of the compressor 1.
When the air suction control device is used, in the air suction stage in the operation process of the compressor 1, the control mechanism 4 transmits a power-off control signal to the electromagnetic valve 5 of the actuating mechanism 2, and the piston rod props against the air inlet valve of the compressor 1 under the action of high-pressure hydraulic oil in the hydraulic oil station 3; in the exhaust stage, the control mechanism 4 continuously transmits a power-off control signal to the electromagnetic valve 5 of the execution mechanism 2, the piston rod continuously keeps a state of forcibly jacking an air inlet valve of the compressor 1, partial gas in a cylinder of the compressor 1 flows back to an air inlet cavity or a pipeline of the compressor through the air inlet valve, after timing is finished, the control mechanism 4 transmits a power-on signal to the electromagnetic valve 5 of the execution mechanism 2, high-pressure hydraulic oil in a piston cylinder flows back to the hydraulic oil station 3, the execution mechanism 2 does not jack the air inlet valve of the compressor 1 any more, the air inlet valve is closed, the compressor 1 compresses residual gas in the cylinder, after compression is finished, the control mechanism 4 transmits a power-off signal to the electromagnetic valve 5 of the execution mechanism 2 again, and the actions are repeated to realize the adjustment of the flow of the compressor.
In conclusion, the utility model can adjust the amount of the compressed gas of the compressor 1, thereby realizing the stepless speed regulation of 0-100 percent of the compressor 1. Meanwhile, the shaft power of the compressor is reduced according to a certain proportion along with the reduction of the displacement, and the energy-saving effect is obvious. Compared with the original manual control of the offshore platform, the stepless speed regulating device has the advantages of quicker response and more accurate regulation, and can be manually cut off after the stepless speed regulating device breaks down, so that the operation of the compressor under the original control system is not influenced.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
