The article deals with mathematical models of the operation of installations for the impregnation of timber based on the effect of the piezo-periodic field, taking into account the difference in the parameters characterizing filtration in the capillaries and pores of the wood. Solutions of differential equations of motion of the front of impregnation are obtained taking into account the harmonic type of the pressure boosting function in the installation; taking into account the initial interval of impregnation, without neglecting the variable nature of the pressure of the impregnating fluid when choosing initial conditions for solving differential equations of motion of the impregnation front. To improve the efficiency of the wood impregnation process, an installation for impregnating wooden blanks using hydraulic shock, which has a simple structure, low energy consumption and the ability to mechanize the process of loading and unloading blanks, has been developed. The rate of impregnation in this way is higher than that of other known methods, since the work pieces are subjected to a double effect: a pulsed increase in pressure, which allows obtaining a periodic force field.
