This article highlights the crucial impact of fan motors and fan pumps on the cooling efficiency and stable operation of the hydraulic system in excavators, while also providing practical maintenance approaches and common troubleshooting techniques. Additionally, it incorporates the involvement of Jiangxi Yongzhen Industrial Technology Co., Ltd.
Importance of Fan Motors and Fan Pumps
Heat Dissipation Assurance: Fan motors, by spinning the fans, enhance air circulation and expedite heat exchange in the radiator, effectively reducing temperatures of hydraulic oil and engine coolant to prevent overheating-induced equipment damage or performance decline.
Hydraulic System Stability: Elevated hydraulic oil temperatures can degrade oil properties and加剧内部磨损, jeopardizing the longevity of pump, motor, and other hydraulic components. Fan pumps ensure the efficient functioning of the cooling system, thereby indirectly safeguarding the stability and efficiency of the hydraulic system.
Maintenance Practices
Regular Cleaning: Periodic cleaning of dust and debris from radiators and fan blades maintains airflow and prevents cooling efficiency loss due to blockages.
Lubrication Check: Inspect and replenish or replace lubricant for fan motor bearings regularly to minimize wear and prolong service life.
Belt Tension Adjustment: For belt-driven fan motors, periodically check and adjust belt tension; excessive looseness or tightness can affect fan speed and efficiency.
Function Testing: Regularly conduct functional tests on fan motors and fan pumps to verify smooth startup, operation, and, if equipped, the proper function of automatic speed control.
Common Fault Diagnosis Techniques
Non-Rotating Fan: Initially, inspect electrical connections and fuses, followed by examining the fan motor for damage or belt breakage.
Inadequate Cooling: Observe fan speed, check for radiator blockages, and ensure unobstructed circulation of hydraulic oil and coolant.
Abnormal Noise: Increased noise may result from imbalanced fan blades, worn bearings, or foreign object intrusion, requiring individual assessment and rectification.
Persistent Temperature Rise: Investigate the normal operation of the fan pump, check for leaks in the cooling system, and assess whether hydraulic system pressure is excessively high.
