The application discloses a process for improving the performance of a excavator and relates to the technical field of excavators. The process comprises the following steps: step S01, starting the engine and making it run at full throttle after preheating and performing digging, soil throwing, walking and lifting operations, detecting and recording the bucket digging force, bucket rod digging force, lifting force and traction force; and step S02, installing a hydraulic system tester on the high-pressure pipeline of the hydraulic pump of a new excavator by using a bypass method, making the pump run at a rated speed, and observing and recording the flow readings of the front and rear pumps of the tester when the hydraulic oil temperature is 50+ / -5 DEG C. The application is a process technology for adjusting the pressure of each working oil cylinder of the main control valve in the hydraulic system of a new or old excavator and the excellent matching of the pump and the engine, fully improves the fuel utilization rate of the engine and the working efficiency and benefit of the whole machine, saves energy and is economical, and can improve and repair the performance and quality of the new or old excavator, such as the digging, crushing, lifting moment and speed.
