In summer, many die-making factories face a common problem: the high temperature alarm of the water chiller causes the laser cutting machine to shut down unexpectedly. However, high-temperature alarms\u00a0of water chillers in summer are\u00a0not caused by hardware failures. They are common issues resulting from extreme ambient temperatures, blocked heat dissipation systems, and inadequate daily maintenance. This article clearly explains the core causes of high-temperature alarms and provides practical, efficient on-site solutions that machine operators can follow directly for troubleshooting.<\/p>\n
Water chillers are equipped with fixed temperature control protection thresholds, which serves as the safe operating limit for the unit. Here is a simple example: if the chiller is set to a cooling water temperature of 35\u00b0C with a temperature difference protection value of 5\u00b0C, the system will fail to dissipate heat normally when the ambient temperature reaches 40\u00b0C or above. As the water temperature continues to exceed the standard, the chiller will automatically trigger a high-temperature alarm and stop working to protect the core components from burnout.<\/p>\n
In tropical and subtropical zones, summer temperatures remain high for a long time, and the indoor temperature of die-making\u00a0workshops can easily exceed 40\u00b0C. Combined with dust accumulation and heat dissipation blockages generated during long-term chiller operation, these two overlapping factors lead to frequent high-temperature alarms.<\/p>\n
The following operations are simple and easy to implement without professional disassembly skills. Machine\u00a0operators can complete the procedures independently to clear alarms and restore normal operation of laser die\u00a0board\u00a0machines quickly.<\/p>\n
