Understanding Water Flow Alarms in Laser Cutting Machine Chillers
When your laser cutting machine suddenly displays a high-temperature water flow alarm, it indicates critical cooling system issues that require immediate attention. This guide explains how to diagnose and resolve these alarms in industrial laser cutting machine chillers.
Common Causes of Water Flow Alarms
1. External Water Line Issues (Laser Cutting Machine Side)
Kinked or clogged cooling water pipes
Loose hose connections in laser cutting machine water cooling system
Blocked filters in the laser cutter's heat exchanger
2. Internal Chiller Problems
Faulty water pump in laser cutting machine chiller
Airlocks in the cooling circuit
Scale buildup restricting flow
Defective flow sensors
Step-by-Step Troubleshooting
Test 1: Isolate the Problem
Short-circuit the chiller's output/return ports with a bypass hose
Restart the laser cutting machine cooling system
If alarm stops → Problem is in external laser cutting machine water lines
If alarm continues → Chiller internal issue
Test 2: Check Water Flow
Observe water flow from output port:
Strong flow → Faulty flow sensor in laser cutting machine chiller
Weak/no flow → Pump failure or blockage
Preventive Maintenance Tips for Laser Cutting Machine Cooling Systems
✔ Monthly inspection of all water lines
✔ Quarterly chiller descaling (use approved cleaners)
✔ Annual pump maintenance
✔ Install water quality monitoring for high-power laser cutting machines
When to Call Professionals
Seek technical support if:
Alarms persist after basic troubleshooting
You notice coolant discoloration
Pump makes unusual noises
