The Noise Fault Analysis and Exclusion in Self-Propelled Transporter Hydraulic System

Abstract:

Noise is one of the common faults in hydraulic system. The correct analysis and deal with the noise will make for the normal operation and optimization of the system. In view of the noise of a new self-propelled transporter suspension hydraulic system produced in the debugging process of the heavy load lifting when suspension falling, by means of mechanism analysis, modeling and simulation analysis of the suspension hydraulic system, finding out the noise comes from the hydraulic component of system with SV type pilot check valve; The noise fault is caused by the improper circuit design of hydraulic system, the feasibility of the using the SL type pilot check valve to eliminate suspension hydraulic system noise proved by the simulation analysis, in the field test of the improved suspension hydraulic system, the suspension falling gentle and noise elimination, which shows that the analysis and simulation model is correct; Through the comparison and analysis on the SV type and SL type kinds of pilot check valve on the reasonable application in the hydraulic circuit isolation, that provides a theoretical basis for the correct selection two kinds of pilot check valve.
