In the operation system of the Tongkuai laser welding machine, the cooling system can be regarded as the "temperature control center", and its stable operation directly determines the welding accuracy and equipment life. When there is an abnormal temperature in the cooling system, it may not only cause a decrease in the performance of the welded joints, but also trigger the equipment protection mechanism to interrupt production. Therefore, establishing a scientific troubleshooting logic to quickly locate and resolve faults is crucial.
The investigation of temperature anomalies should follow the principle of "from the surface to the inside, from easy to difficult", and the first step is to verify the basic state. The operator should first confirm the core parameter settings of the cooling system, compare with the equipment manual to check whether the temperature control threshold is reasonable, and avoid false alarms caused by parameter adjustments. At the same time, check if the coolant level is within the standard range. If the level is below the lower limit, it is necessary to replenish the same type of coolant - it is important to note that different brands of coolant should not be mixed to avoid chemical reactions that may block the circuit. In addition, cleanliness inspection is essential. Dust and welding slag accumulation on the surface of the filter and radiator can significantly reduce the heat dissipation efficiency. Compressed air blowing combined with low-pressure water flow flushing can be used for cleaning.
If there are no abnormalities in the basic verification, it is necessary to thoroughly investigate the performance of the circuit and components. Firstly, check the sealing of the pipeline, focusing on whether the sealing ring and clamp at the interface are aged and loose. The leakage point can be located by applying soapy water and observing the bubbles. Next, check the working conditions of the circulating pump, monitor whether there are any abnormal noises during operation, and observe the changes in pressure gauge values. If the pressure fluctuates too much or there is no pressure display, it may be due to wear of the pump impeller or motor failure, and it needs to be disassembled, repaired or replaced. For temperature control sensors, professional instruments can be used to test their measurement accuracy. If the deviation exceeds the allowable range, it needs to be recalibrated or replaced to avoid temperature control misalignment caused by signal distortion.
After the fault is resolved, a long-term guarantee mechanism needs to be established. Regularly record the operating parameters of the cooling system, including temperature, pressure, liquid level, etc., and predict potential faults in advance through trend analysis. Develop a periodic maintenance plan, replace the coolant once every quarter, and thoroughly clear the pipeline once a year to ensure long-term stable operation of the system. In addition, operators need to receive professional training, familiarize themselves with the meaning of fault alarm codes and basic troubleshooting procedures, and enhance their emergency response capabilities.
The core of troubleshooting temperature anomalies in the cooling system of the Tongkuai laser welding machine lies in accurately locating the source of the fault. Through standardized troubleshooting procedures, meticulous component testing, and comprehensive maintenance mechanisms, the occurrence rate of failures can be effectively reduced, ensuring the continuity and stability of welding production.
