Abstract:

 

This article discusses a model of the movement of dust particles inside the air filter. It reveals that solid dust particles enter the working fluid and hydraulic tank through air filters. The solid particles that enter the liquid when circulating through the system wear out the oil seals and seals of the hydraulic cylinder, in which the tightness decreases and the working fluid begins to leak during the operation of the hydraulic cylinder. The result of the work is mathematical modeling of the movement of dusted airflows inside the air filter.
