Vibrodiagnostic investigations at a chain drive stand of a sucker rod well pump

Abstract

Relevance of the research. Nowadays application of sucker rod well pumping installations is the simplest and reliable way of oil production. Since 2000 chain drives on the basis of a reducing conversion mechanism have been widely used. Their main advantages are: the ability to adjust the stroke length and frequency control, without increasing the mass and dimensions of the drive; uniform speed of the sucker rod on the prevailing part of the stroke; a reducer with a smaller gear ratio and a torque is used; reduction of energy costs. The important component of reliable operation is data collection and analysis of chain drive operation.The aim of the work is to carry out the experiments and analyze the obtained values of the chain drive vibration using the roller and tooth chains. Research methods: experimental studies and analysis of the influence of chain tension on the vibrodiagnostic complex. Results. The authors have designed the experimental installation of a chain drive for investigation of forced oscillations of a roller and tooth chain with and without a tensioner, toothed and roller chains; analyzed the chain drive vibration and plotted the graph of the influence of chain tension on the amplitude of forced oscillations. Spectral analysis of the forced oscillations amplitude of the chain drive was carried out.
