Abstract: | |
Avoiding pipe vibration is an important aspect of reciprocating compressor system design. By modal analysis upon a secondary compressor inlet pipe to get the natural frequency of the pipe, using the transfer matrix method to calculate the natural frequency of the pipe column. Compared with the excitation frequency of the compressor, it reveals the cause of the pipe vibration is mainly due to the natural frequency of pipe column in the region of the compressor excitation frequency. Calculating the pipe stresses under the pulsating action of the exciting force and it far exceeds the allowable stress of pipe. By changing the secondary intake pipe length, increasing intake surge tank and theoretical analysis of the system show that changes in the structure of solution effectively avoids the resonance length of the pipe, significantly reduces the stress and vibration of the pipe. The field secondary inlet pipe of the reciprocating compressor after transformation doesn’t lead severe vibration and break accident again. It confirms the feasibility of theory study. |
