Determination of diagnostic errors in the system of diagnostic parameters of hydraulic drives of construction and road machinery

Problem. The article considers the issue of increasing efficiency operation construction machines by improving systems measures that provide an effective system for diagnosing hydraulic drive elements. considered existing methods prove a more determination indicators diagnostic parameters in with error devices themselves drives and road will be equipment gives necessary result lower overall costs diagnostics minimal costs, including cost equipment, its development, as well preparing diagnosis. Goal. goal is errors machinery. Methodology In technical diagnostics, test functional are used. During diagnosis, actions used set working processes drive. special applied to units. condition units evaluated based on reaction these actions. Functional actions, between which there no clear boundaries, carried out only within characteristics unit. Results. A required diagnostics. These include Originality. Accuracy this case determined analytical dependence connects other depending type dependence. Thus, it was established use rotation frequency pump compared passport data increases share leaks total flow fluid allows reduce 40...60% without additional purchase measuring devices. Changing possible Methods ensuring accuracy currently insufficiently improve unused reserve efficiency. Practical value. Efficiency increased
