Research on Fault Diagnosis Method of Reciprocating Compressor Based on RSSD and Optimized Parameter RCMDE

open access: yesApplied Sciences
As for the fault diagnosis process of a reciprocating compressor, vibration signals are often non-stationary, nonlinear, and multi-coupled, which makes it difficult to conduct effective fault information extraction.

Vibration Analysis of a Single-Cylinder Reciprocating Compressor considering the Coupling Effects of Torsional Vibration

open access: yesShock and Vibration, 2019
A piston slap is one of the main vibration sources of the reciprocating machinery. Much work has been done in this field, most of which was based on a constant rotating speed.

Equal Probability Association Rule for Reciprocating Compressor Diagnosis under Variable Speed Working Condition

open access: yesShiyou jixie, 2019
When the reciprocating compressor is working at variable speed, the characteristic index of the vibration signal shows variability and instability, resulting in reduced correct rate of the equipment state diagnosis directly judged by the feature.

Performance of a transcritical carbon dioxide heat pump for simultaneous refrigeration and water heating : a thesis presented in partial fulfilment of the requirements for the degree of Master of Technology at Massey University [PDF]

open access: yes, 1998
Many industrial processes require both refrigeration to less than 0°C and water heating to greater than 60°C. Traditional independent refrigeration and boiler systems have relatively poor energy efficiency, whilst conventional heat pumps can provide both

The gate studies: Assessing the potential of future small general aviation turbine engines [PDF]

open access: yes
Four studies were completed that explore the opportunities for future General Aviation turbine engines (GATE) in the 150-1000 SHP class. These studies forecasted the potential impact of advanced technology turbine engines in the post-1988 market ...

Piston ring assembly for a new natural gas vehicle symmetrical multistage wobble-plate compressor [PDF]

open access: yes, 2006
Natural gas is an alternative fuel of choice in the market today due to the increase in the price of petroleum, as well as out of environmental concerns. Pressure requirement for a natural gas vehicle (NGV) storage tank is 3000 psig (206 bars).

Response Spectrum Analysis of the Domestic Piston of Reciprocating Compressor Based on ANSYS

open access: yesShiyou jixie, 2017
To evaluate the working performance of the domestic piston on reciprocating compressor, taking the crankshaft connecting-rod movement to the dead point as study object, analyses on the modal and response spectrum of the piston and piston rod have been ...

The Gas Transportation Network as a ‘Lego’ Game: How to Play with It? [PDF]

open access: yes
Gas transportation networks exhibit a quite substantial variety of technical and economical properties ranges roughly from an entrenched natural monopoly to near to an open competition platform. This empirical fact is widely known and accepted.

Vibration analysis in reciprocating compressors

open access: yesIOP Conference Series: Materials Science and Engineering, 2017
This paper presents the influence of modelling on the mechanical natural frequencies, the effect of inertia loads on the structure vibration, the impact of the crank gear damping on speed fluctuation to ensure a safe operation and increasing the reliability of reciprocating compressors.
