Jianming Machinery’s efficient solutions to excavator malfunctions

In the construction machinery industry, excavators are hailed as the “hands of construction,” and the engine is the “heart” of these hands. Recently, the after-sales technical team from Jianming Machinery went deep into the front-line repair workshop and, with their superb professional skills and meticulous service attitude, successfully solved a long-term customer’s problem of insufficient excavator power.

Precise Diagnosis: Letting the Data Speak

In the photo, the hood of this large yellow excavator has been opened, revealing its complex mechanical structure. Jianming Machinery technical experts did not rush to disassemble it, but instead adopted a scientific approach of diagnosing first, then treating.

Multi-dimensional Testing: Core technical personnel are using high-precision electronic diagnostic instruments to monitor the engine’s ECU data in real time.

Collaborative Discussion: Three technicians gathered around the engine, conducting in-depth analysis of the monitored pressure values ​​and abnormal fuel consumption.

In-depth Investigation: By checking the coupling status of the intake system, fuel injection system, and hydraulic pump, the fault was ultimately identified as incomplete fuel combustion caused by injection timing misalignment.
