Reliability And Running Efficiency Of Equipment Affected By The Airflow Ripple Of Air-compressor

The airflow ripple and pipeline quiver during the moving of air-compressor used in the coalmine was searched. The mathematics modelwas set up based on the criterion structure of design and install of air-compressor. The related boundary condition was confirmed and thesoftware was compiled by the install condition of ventilating pipeline. Aircolumn syntony in the ventilating pipeline system, pipeline structuresyntony and airflow ripple were simulated and analyzed by computer onthe above basis work, and compared the results between the simulatedresult and experienced result.The experience analysis and the theory suggested that the pipelinedesigning length is the key factor of influencing syntony frequency ofventilating pipeline structure and systematic air column. In certain designpipe length, the systematic syntony will be caused by the opening andclosing of valves of ventilating pipeline system of compressor. Theinfluencing factors of airflow ripple in the pipeline on the economic runof the air-compressor and the measures of increasing economic runningwere put forward.
