Abstract

The article presents the results of experimental studies of the steam screw machine-200 steam screw machine, which is promising for use as an autonomous power plant for remote forest terminals that carry out deep processing of wood. The purpose of the work was to verify the theoretical linear model of the power-steam flow rate relationship by establishing and analyzing the actual power-steam flow rate relationship. Bench tests were conducted at five fixed modes. Based on the experimental data, a new approximate power-law relationship was obtained. A statistical comparison with the theoretical model using the Pearson test showed that the differences between the theoretical and new data are statistically significant, indicating that the theoretical model is insufficient.
