Technical Transformation and Operation Optimization of 4DI110 Air Compressor
This paper introduces the newly introduced 4DI110 centrifugal air compressor(hereinafter referred to as:This paper analyzes the influence of operating conditions and air temperature changes on the outlet flow rate of air compressor since the start of trial operation stage.It points out that the outlet flow rate of air compressor varies with air temperature.It is pointed out that the V3004 valve of the air compressor cannot automatically adjust the outlet pressure,which affects the stability of the working condition of the air separation unit.In order to keep the outlet pressure of the air compressor stable,the air compressor V3004 valve is modified with the addition of the automatic bypass valve and the V3008 valve.At the same time,the relevant logic control is optimized and perfected,and the operation optimization and practical results obtained after the technical modification are described.
