The Problems That Arise When Analyzing the Technical State of Modern Drives  of Compressor Installations of Main Gas Pipeline

A wide application of the rotary-type machines as actuating mechanisms and driving units in the oil&gas industry stipulates for a special approach towards the diagnostics of the current state of their elements. Roller bearings of such machines are the most critical joints as they are under constant action of significant power and oscillatory loads. Generally, failures of roller bearings cause the destruction of not only the bearings but also the contacting parts. Modern dynamic methods of diagnosing the unit and machine technical state, in particular, vibration diagnostics, allow avoiding emergency and hazardous situations, unreasonable and unscheduled stops and expensive visits of the manufacturer’s specialist. The article considers the existing methods of diagnosing the rolling bearings state by vibration parameters. As a rule, most modern methods are based on quite precise mathematical calculations of vibration components, require the application of specialized and expensive software and do not provide a possibility to make a precise conclusion on the researched object technical state at practice. The article considers the method of detecting the technical state of roller bearings which can be applicable in most cases. This method reveals the general forms of spectral modulations, reflecting the presence of incipient and developing faults, and defines the real values of a diagnostic sample - test spectrum, uses very few mathematical calculations and does not require all the standard bearing geometrical parameters during analysis.

Today no gas purification method exists which can be considered absolutely efficient. Thus, when gas compilation in conducted a problem of sediment formation occurs in a flow passage of the gas compression station (GCS) injector. The paper considers the mathematical simulation of the force moment change at the injector impeller of GCS caused by sediment occurrence in the interblade channel of impellers. In addition, the authors study the change of force moment in relation to the thickness of a sediment layer. Also, the research concentrates on the change of circumferential force at the impeller due to the change of force moment.
