YIN Jia1, WU Jian-de1, WANG Xiao-dong1, et al. Study on fault diagnosis of reciprocating diaphragm pump spindle based on HHT[J]. 2013, 32(4): 5-8. DOI: 10.13873/j.1000-97872013.04.008.
Reciprocating diaphragm pump is one of the most important equipment in the pipeline transportation industry
at the same time
it is also one of the most easily damaged equipment.The running performance of reciprocating diaphragm pump spindle affects reciprocating diaphragm pump operating conditions directly
even the effective operation of the entire pipeline transportation systems.Proposes HHT method which combines of empirical mode decomposition(EMD)and Hilbert transform is used to diagnose and analyze reciprocating diaphragm pump spindle failure
equipment failure analysis and diagnosis through the marginal spectrum effectively.The experiments show that the reciprocating diaphragm pump spindle fault diagnosis based on the HHT method is effective and feasible.
