Research on Dry Gas Seal End Face Characteristics of Coal Bed Methane Compressor
In order to solve the problem of coal bed methane leakage from the shaft end of the compressor,based on the current research situation at home and abroad,we analyse the principle of dry gas sealing in spiral groove,establish the dry gas sealing model,and analyse the air film performance of the dry gas sealing end face,find out the internal and external parameters affecting the sealing performance using numerical simulation,and find out the optimal range of the relevant parameters using the method of controlling variables,and finally put forward optimization theory for the dry gas sealing of coal bed methane compressor through simulation results.Finally,through the simulation results,the optimisation theory is proposed for the dry gas seal of coal bed methane compressor.
