Embodiment Construction

[0018] In order to achieve the above technical purpose, the large-flow adjustable and stable continuous compressed air source system designed by the present invention includes a screw compressor, a compressor power distribution system, a refrigerated dryer, a filter, an air storage tank, a pipeline system, and a cooling system. It consists of circulating water pump, fan system, valve system, temperature and pressure sensor, central control system and other parts.

[0019] The described screw compressors supply 17 units, and the maximum flow rate of a single compressor is 84.7Nm 3 / min, the maximum discharge pressure is 0.75MPa, the rated voltage of the compressor is 6kv, and the rated power is 500kw. Although the screw compressor has a small flow rate, compared with the centrifugal compressor, the screw compressor discharge is uniform, stable and continuous, which is suitable for the situation where the compressed air quality is higher in the test area of ​​this project.

Abstract

The invention provides an adjustable large-flow compressed air source system which comprises a plurality of compressor air supply pipelines. Compressors are screw type compressors. Each compressor air supply pipeline finally communicates with an air supply main pipeline through a filter and a refrigeration dryer. An electric butterfly valve is arranged in the joint of each compressor air supply pipeline and the air supply main pipeline and used for adjusting the compressed air flow rate and pressure. According to the adjustable large-flow compressed air source system, the flow rate is adjusted in a grouped control mode, the configured adjustment flow rate is selected through a control system, and continuous and stable use requirements from the minimum flow rate to the maximum flow rate are met. The adjustable large-flow compressed air source system can be used for supplying air stably and continuously in a large-flow adjustable mode.

Description

technical field [0001] The invention relates to a stable compressed air source system with large flow rate and automatic adjustment. Background technique [0002] Compressed air is a commonly used medium in industrial production and scientific research and testing activities. It has the characteristics of convenient transportation, no open flame, no load, strong adaptability to the working environment, and convenient material acquisition. The compressed air source system is a system that generates compressed air. [0003] The compressed air source system is mainly composed of compressors and auxiliary equipment. The compressors generally include screw compressors, centrifuges, etc. The screw compressor produces a stable gas source but a small flow rate, and the centrifuge has a large gas source flow but the gas is discontinuous. The domestic air compressor stations currently in use have the following characteristics: [0004] 1. The air supply of the air compressor station...
