Tech Transfer’s success rate with pulsation analysis is unparalleled in the reciprocating compressor industry.

Tech Transfer initially developed its pulsation analysis technology to support its field vibration analysis of compressors. Today, Tech Transfer is a world leader in the pulsation and vibration analysis of reciprocating compressors. We perform pulsation analyses in complete compliance with API 618 and all of its options for stress and dynamic analysis.

Mechanical natural frequency analysis is performed with Finite Element programs and the results match our field readings. Our knowledge of cylinder stiffness, bottle design and pipe support methods were developed from field vibration analysis results. On many occasions, Tech Transfer has been given the opportunity to field-verify our pulsation levels and mechanical natural frequencies and our calculations match field readings.

The following analysis plots illustrate that near acceptable pulsations (3.3 psi) can generate excessive shaking forces (580 lbs) at a higher frequency of 10X operating speed. Proper analysis techniques will detect and correct such problems.
