Analysis and troubleshooting of core components of excavator hydraulic system
The hydraulic system serves as the power lifeline of an excavator, using hydraulic oil as the transmission medium to convert the mechanical energy output by the engine into high-pressure hydraulic energy. This energy is then accurately distributed to actuators such as hydraulic cylinders and travel motors via control components, completing a full set of heavy-duty operations including boom lifting, bucket digging, slewing and traveling. Among them, the main pump and multi-way valve are the two core components of the hydraulic system, which directly determine the machine’s operating efficiency, movement smoothness and load capacity. They are also the key targets of daily troubleshooting, and most hydraulic system faults can be resolved by focusing on these two components.Analysis and troubleshooting of core components of excavator hydraulic system
