The hydraulic pump harness is the "nerve center" that connects key components such as the excavator main controller (computer board), pump controller, solenoid valve, pressure sensor, etc. with the hydraulic pump. Its core function is to transmit precise control signals (such as displacement control, pressure feedback) and stable power supply, ensuring that the hydraulic pump can adjust flow and pressure in real time and accurately according to operating instructions. As an original component, it is made of high-quality materials: the wire is high-purity tin plated copper wire, ensuring low resistance and excellent conductivity; The insulation layer is made of PP/PUR material that is oil resistant, high temperature resistant (usually tested at -40 ℃~125 ℃), wear-resistant, and flame-retardant.

To ensure the long-term reliable operation of the hydraulic pump harness, regular inspections and preventive maintenance must be carried out. It is recommended to check the appearance of the wiring harness every week or every 50 hours of work, with a focus on the areas near the hydraulic pump and the turning points of the frame that are susceptible to high-temperature hydraulic oil erosion, vibration, and friction. Check whether the insulation layer is cracked, hardened, damaged, or worn by metal edges and corners. It is crucial to keep the connector clean and dry. When disassembling, be sure to disconnect the power supply first and hold the connector body for operation. It is strictly forbidden to directly pull or tug on the wires.
