If a Danfoss hydraulic pump is overheating due to improper use of the hydraulic system, the underlying problem must be addressed. Here are some steps to take: 1. Identify abnormal use: Determine the specific factors or conditions that lead to abnormal use of the hydraulic system. This could include excessive load, prolonged operation without rest, incorrect operating procedures, or other factors. 2. Check system specifications: Check system specifications and make sure the hydraulic pump is sized and rated for the intended application. Verify that operating parameters (pressure, flow, temperature) are within the design limits of the pump. 3. Check fluid levels and condition: Check the hydraulic fluid levels and make sure they are within the recommended range. Check the condition of the hydraulic fluid for contamination or deterioration. Contaminated or degraded fluids can cause increased friction and heat generation. 4. Verify cooling system: Check cooling system components such as coolers, fans, and related controls. Ensure proper airflow and cooling to prevent overheating. If necessary, clean or replace the cooler and make sure the fans are operating properly. 5. Check for leaks and restrictions: Check the hydraulic system for any leaks, restrictions or blockages. Leaks cause pressure loss and increased load on the pump, while restrictions cause excess pressure and heat generation. Fix any leaks and resolve any limitations. 90R130-KA-5-AB-80-L-3-F1-H-03-GBA-42-42-24 90R130KA5AB80L3F1H03GBA424224 90-R-130-KA-5-AB-80-L-3-F1-H-03-GBA-35-35-24 90R130KA5AB80L3F1H03GBA353524 90R130-KA-5-AB-80-L-3-F1-H-03-GBA-35-35-24 90R130KA5AB80L3F1H03GBA353524 90-R-130-KA-5-AB-80-L-3-C8-H-04-GBA-26-26-24 90R130KA5AB80L3C8H04GBA262624 90R130-KA-5-AB-80-L-3-C8-H-04-GBA-26-26-24 90R130KA5AB80L3C8H04GBA262624 90-R-130-KA-5-AB-80-L-3-C8-H-03-GBA-38-14-30 90R130KA5AB80L3C8H03GBA381430 90R130-KA-5-AB-80-L-3-C8-H-03-GBA-38-14-30 90R130KA5AB80L3C8H03GBA381430 90-R-130-KA-2-NN-80-R-3-C8-H-03-GBA-26-26-24 90R130KA2NN80R3C8H03GBA262624 90R130-KA-2-NN-80-R-3-C8-H-03-GBA-26-26-24 90R130KA2NN80R3C8H03GBA262624 90R130-KA-2-NN-80-R-3-C8-F-06-GBA-42-42-24 90R130KA2NN80R3C8F06GBA424224 6. Monitoring system pressure and temperature: Install pressure and temperature gauges in the hydraulic system to monitor the operating conditions. This will help identify any unusual spikes or fluctuations that may be causing the pump to overheat. 7. Adjust the operating procedures: review and adjust the operating procedures to ensure the correct use of the hydraulic system. Train operators in proper operating techniques, including load management, rest periods, and temperature monitoring. 8. Seek professional help: If the problem persists or you are not sure about the root cause of the overheating, it is recommended to contact a professional technician or Danfoss Support for further assistance. They can provide specific guidance based on pump model and application. 9. Optimizing System Design: Review the overall design of the hydraulic system to ensure it is designed for the intended application. Consider factors such as pipe size, component selection, and flow control to optimize system efficiency and reduce load on hydraulic pumps. 10. Control system temperature: Take temperature control measures such as installing temperature sensors and using temperature control valves. These can help regulate operating temperatures within acceptable limits and prevent overheating. 11. Use proper fluid viscosity: Make sure the hydraulic oil used in the system has the proper viscosity for the operating conditions. Using fluids with viscosities outside the recommended range can cause excessive friction and heat. 12. Carry out regular maintenance: establish a daily maintenance plan to inspect and repair hydraulic system components. This includes cleaning filters, replacing worn seals and O-rings, and inspecting pumps and other system components for any signs of wear or damage. 13. Monitor and adjust system parameters: Continuously monitor system parameters such as pressure, flow, and temperature during operation. If any anomalies are detected, make adjustments as needed to optimize system performance and prevent overheating. 14. Provide operator training: Make sure operators receive proper training on hydraulic system operation and maintenance. Educate them about the risks of abnormal use and the importance of following proper operating procedures. 15. Review system load requirements: Assess the load requirements of the hydraulic system and consider whether any modifications or adjustments can be made to reduce the load on the hydraulic pumps. This may include redistribution of load, optimization of system layout or upgrade of components where necessary. 16. Implement system monitoring and diagnostics: If possible, install a hydraulic system monitoring and diagnostic system to continuously monitor various parameters such as temperature, pressure, and flow. This provides real-time data and alerts for abnormal conditions, enabling proactive maintenance and troubleshooting. 17. Consider System Upgrades: Assess the possibility of upgrading certain components or subsystems of the hydraulic system to improve its efficiency and performance. This may include upgrading the pump to a higher capacity model or improving the cooling system. 18. Improve ventilation and heat dissipation: ensure adequate ventilation and heat dissipation of the hydraulic system. Consider adding additional cooling elements such as heat exchangers or fans to increase cooling capacity, especially in high-temperature environments or during heavy-duty operations. 90-R-130-KA-2-DE-80-R-4-F1-H-00-GBA-38-38-24 90R130KA2DE80R4F1H00GBA383824 90R130-KA-2-DE-80-R-4-F1-H-00-GBA-38-38-24 90R130KA2DE80R4F1H00GBA383824 90-R-130-KA-2-CD-80-R-4-F1-H-00-GBA-38-38-24 90R130KA2CD80R4F1H00GBA383824 90R130-KA-2-CD-80-R-4-F1-H-00-GBA-38-38-24 90R130KA2CD80R4F1H00GBA383824 90-R-130-KA-2-CD-80-R-3-C8-H-04-GBA-40-40-24 90R130KA2CD80R3C8H04GBA404024 90R130-KA-2-CD-80-R-3-C8-H-04-GBA-40-40-24 90R130KA2CD80R3C8H04GBA404024 90-R-130-KA-1-NN-80-S-4-C8-F-04-GBA-26-26-24 90R130KA1NN80S4C8F04GBA262624 90R130-KA-1-NN-80-S-4-C8-F-04-GBA-26-26-24 90R130KA1NN80S4C8F04GBA262624 90-R-130-KA-1-NN-80-S-4-C8-F-02-GBA-29-29-20 90R130KA1NN80S4C8F02GBA292920 90-R-130-KA-1-NN-80-S-3-F1-F-04-GBA-38-38-24 90R130KA1NN80S3F1F04GBA383824 19.

This helps identify areas that are generating excessive heat or that are poorly dissipated, enabling targeted maintenance and corrective action. 20. Review working conditions and duty cycle: Evaluate the working conditions and duty cycle of the hydraulic system. Evaluate whether the system is operating within its intended limits and make necessary adjustments to prevent overloading and overheating. 21. Record and analyze operating data: Maintain detailed records of operating parameters, maintenance activities and any abnormal events. This data is analyzed over time to identify patterns or recurring problems that may be causing the hydraulic pump to overheat. This can guide future maintenance and troubleshooting efforts. 22. Seek expert help: If the problem persists or becomes complicated, consider consulting a hydraulics specialist or Danfoss Technical Support. They can provide professional insight and advice based on their knowledge and experience. Remember, it's important to address the root cause of abnormal usage that's causing your hydraulic pump to overheat. Taking a systematic and comprehensive approach to maintenance, monitoring and system optimization will help reduce the risk of overheating and ensure reliable operation of Danfoss hydraulic pumps.
