When the hydraulic system is used abnormally and the hydraulic pump is overheated, the cause must be found out and resolved in time. Excessive heat can result in reduced pump efficiency, damage to system components, and potential system failure. Here are some steps to diagnose and resolve the issue: 1. Check fluid level and condition: Make sure the hydraulic fluid level is adequate and in good condition. Low or contaminated fluids can cause increased friction and heat. If hydraulic fluid has deteriorated or become contaminated, replace with recommended hydraulic fluid. 2. Check for leaks: Check the system for leaks, as even a small leak can cause the liquid level to drop and increase the pump's workload, which can lead to overheating. Address any leaks found immediately. 3. Check the system pressure: Excessive system pressure will cause the pump to work harder, which can lead to overheating. Check the system pressure with a pressure gauge to make sure it is within the recommended operating range. If the specified limit is exceeded, adjust the pressure to the correct level. 4. Monitoring system temperature: Install temperature sensors in key areas of the hydraulic system to monitor the temperature. This allows you to detect overheating problems early and take corrective action before serious damage occurs. 5. Check whether the viscosity does not match: Make sure the viscosity of the hydraulic oil meets the system requirements. Using a fluid with the wrong viscosity will result in increased internal friction and heating.

Verify pump speed: Check that the pump is running at the correct speed. Running the pump at a higher speed than recommended may cause it to overheat. Adjust pump speed to proper level if necessary. 7. Evaluate system design: Review the entire system design to ensure it meets the requirements of the application. Inadequate or incorrect system design can place an excessive load on the pump, causing it to overheat. 8. Verify Load Conditions: Assess the system's load conditions and make sure they are within the pump's capacity. Overloading the pump beyond its capacity may cause overheating. 9. Monitor pump efficiency: Check the efficiency of the pump regularly to detect any drop in performance that may indicate a potential overheating problem. 10. Consider cooling solutions: If your hydraulic system is constantly operating at high temperatures, consider adding cooling components, such as coolers or heat exchangers, to dissipate excess heat from the system. 11. Preventive Maintenance: Implement a regular maintenance program, including filter changes and system inspections, to prevent potential problems and ensure optimal operation of the hydraulic system. 12. Clean hydraulic components: Contaminants such as dirt, debris, and sludge can accumulate in hydraulic systems and increase friction, leading to overheating. Regularly clean hydraulic components, including filters, reservoirs and lines, to maintain optimum system performance.

Check the alignment of the pump: Improper alignment of the pump to the drive system can cause excessive friction and heat. Make sure the pump and motor or engine are properly aligned to minimize energy loss and overheating. 14. Review working conditions: Evaluate the working conditions of the hydraulic system, such as temperature, humidity and surrounding environment. Extreme conditions can affect pump performance and cause overheating. 15. Use a pressure relief valve: Installing a pressure relief valve in a hydraulic system can protect the pump from overloading during sudden pressure spikes and prevent overheating due to excessive pressure. 16. Monitor the pump inlet condition: Check the pump inlet condition, including the presence of air or aeration. Air in hydraulic fluid can cause cavitation and affect pump efficiency, leading to overheating. Make sure to start properly and remove air from the system. 17. Inspect pump components: Inspect the internal parts of the pump, such as seals, bearings, and pistons, for wear and damage. Faulty components can reduce pump efficiency and cause overheating. Replace any worn or damaged parts as needed. 18. Consider pump type and size: Evaluate whether the current pump type and size is suitable for the application. Using an undersized pump or a pump that does not meet the system requirements may result in constant overloading and overheating. Consider upgrading to a more suitable pump if necessary. 19. Training and Operator Awareness: Make sure system operators are adequately trained in the proper use and maintenance of hydraulic systems. Operator error or misuse can cause overheating problems. 20. Monitor System Performance: Implement a system to regularly monitor and record hydraulic system performance. Track temperature trends, pressure levels and pump efficiency to detect any abnormal patterns that may indicate potential overheating issues.

Consider expert consultation: If the cause of the overheating is still unclear, or if the problem persists despite corrective actions, consider seeking help from a hydraulics specialist or the pump manufacturer's technical support team. 22. Optimize system filtration: Make sure the hydraulic system is equipped with a proper filtration system. Proper filtration helps to remove contaminants from the fluid, reduces the risk of abrasive wear and increases the efficiency of the pump, which helps prevent overheating. 23. Use high-quality hydraulic oil: Selecting high-quality hydraulic oil that meets or exceeds system specifications can help with better lubrication and heat dissipation, and help alleviate overheating. 24. Implement insulation: In situations where hydraulic systems are exposed to external heat sources, consider insulating critical components. Thermal insulation can help maintain a stable operating temperature and prevent overheating due to external heat transfer. 25. Control system loads: If your hydraulic system has variable load requirements, consider using load sensing or flow sharing techniques to match pump output to actual demand. This optimizes energy use and minimizes overheating during periods of low demand. 26. Consider multi-pump arrangements: For larger hydraulic systems, consider using multiple smaller pumps in a parallel or series arrangement. This configuration distributes the workload more evenly and reduces the risk of overheating. 27. Verify System Flushing: If the hydraulic system has been maintained or repaired, make sure it has been thoroughly flushed to remove any residual contaminants that could cause increased friction and overheating. Keep in mind that each hydraulic system is unique and an overheating solution may require a combination of measures. Troubleshooting, regular maintenance and monitoring of system faults can help to detect and solve overheating problems in a timely manner, ensuring the reliability and efficient operation of the hydraulic system. If the overheating problem persists after taking corrective actions, it is recommended to seek the assistance of a qualified hydraulic engineer or technician with expertise in diagnosing and resolving complex hydraulic problems.
