Gas compressor system

Abstract

The invention provides a gas compressor system. The gas compressor system is characterized by comprising a gas compressor, a control system connected with the gas compressor, and a motoring end connected with the gas compressor system, wherein the gas compressor is provided with an inlet guide vane which is connected with the gas compressor system, a backflow valve which is connected with the gas compressor system, and provided with an exhaust port connected with an intake port of the inlet guide vane, a first-stage compression device which is provided with an intake port connected with an exhaust port of the inlet guide vane, and a second-stage compression device which is provided with an intake port connected with an exhaust port of the first-stage compression device, and provided with an exhaust port connected with an intake port of the backflow valve; and the control system is provided with an inlet guide vane control system used for controlling the inlet guide vane, and a backflow valve control system used for controlling the backflow valve.

Description

technical field [0001] The invention relates to the field of industrial automatic control, in particular to a gas compressor system for controlling a gas compressor. Background technique [0002] Gas compressor is the basic product of industrial modernization. It is often said that electricity and automation have the meaning of full pneumatic; and gas compressor is to provide air source power, which is the core equipment of the pneumatic system and the main body of the electromechanical induced air source device. It is a device that converts the mechanical energy of the prime mover (usually a motor) into gas pressure energy, and is a gas pressure generating device that compresses gas. [0003] my country's large-scale continuous operation gas compressors are basically imported from abroad in complete sets. The imported control system is not open and difficult to maintain. Once a problem occurs in the system, it cannot be found and tracked, which affects production; and the c...

Problems solved by technology

[0003] my country's large-scale continuous operation gas compressors are basically imported from abroad in complete sets. The imported control system is not open and difficult to maintain. Once a problem occurs in the system, it cannot be found and tracked, which affects production; and the imported control system has high spare parts and high service costs. , the one-time investment cost is also high

[0004] Domestic gas compressors are relatively backward in control technology, basically for low-power gas compressors, and the control accuracy is low, the instantaneous response is slow, easy to trip, the output pressure fluctuates greatly, and the power consumption is high. The impact is relatively large
