Fault Diagnosis of Reciprocating Compressor Using Pressure Pulsations
The major problems encountered in a reciprocating compressor are because of the valve failure .The other problem of leakage past the piston because of the worn out piston rings has also been placed in the reciprocating compressor. Pressure pulsations generated inside the piping of a reciprocating compressor may be taken as one of the tool for diagnosing the nature of fault inside the compressor...
متن کاملFault classification using an Artificial Neural Network based on Vibrations from a Reciprocating Compressor
Reciprocating compressors are widely used in industry for various purposes and faults occurring in them can degrade performance, consume additional energy, and even cause severe damage to the machine. This paper will develop an automated approach to condition classification of a reciprocating compressor based on vibration measurements. Both the time domain and frequency domain techniques have b...
متن کاملThe Dynamics Of Reciprocating Compressor Valve Springs
The valves in reciprocating compressors use springs to control the timing of the valve closing. These springs are subjected to dynamic loading by the motion of the valve element. The element motion is periodic, but includes rapid acceleration and deceleration. It can therefore excite a wide range of frequencies in the spring. The resulting spring surge creates high stresses and is a major contr...
متن کاملValve Dynamics and Internal Waves in a Reciprocating Compressor
Internal pressure waves influence the performance of reciprocating compressors in two ways: Firstly they interact with the valve dynamics and secondly they excite an oscillating moment onto the piston. On the basis of 2-D and 3-D simulations using a commercial CFD code and the experiences of compressor manufacturers a 1-D flow model is introduced. Valve dynamics are described by a modified Cost...
متن کاملComplex Dynamics and Symbolic Dynamics
Robert L. Devaney, Boston University Synopsis As so often happens in mathematics, there is a surprising connection between two quite distinct subfields of dynamical systems theory, namely the structure of the automorphism group of the one sided shift map on d-symbols and the topology of the analogue of the Mandelbrot set for degree d polynomials of one complex variable. In this lecture we will ...
