What to Do When an Air Compressor Stops Suddenly?
01 Sudden Shutdown: The Golden 5-Minute Self-Help Procedure
Step 1: Stay Calm and Check in Order
1. Check the control panel for alarm codes (note the specific code).
2. Check if the power supply is normal (safe range: voltage fluctuation ±10%).
3. Gently touch the unit casing with the back of your hand to check the temperature (requires emergency handling if exceeding 90°C).
Step 2: Quick Response Based on Alarm Code
High Temperature Alarm: Immediately check if the cooling fan is running; clean the clogged cooler.
Overload Alarm: Check if the motor bearing is seized; check if the belt is too tight.
Pressure Abnormal:Check the pressure sensor connection; clean the filter.
Step 3: Attempt a Safe Restart
1. Press the emergency stop button and then reset it.
2. Wait 5 minutes for the unit to cool down.
3. Restart and observe the operating status.
02 On-Site Quick Troubleshooting Guide for Common Faults
Case 1: Motor Fails to Start (50% of faults start here)
Checklist:
Power supply voltage (Allowable fluctuation range: Rated voltage ±10%).
Circuit breaker status (Test after resetting).
Contactor contacts (Replace if burnt).
Case 2: Insufficient Air Production Pressure (30% of customers have encountered this)
Quick Handling:
1. Check the air intake filter element (replace immediately if clogged).
2. Check the minimum pressure valve (repair if not sealing properly).
3. Check the oil separator element (must replace if pressure difference > 0.12 MPa).
Case 3: Abnormal Noise (The most easily overlooked danger signal)
Emergency Handling:
Stop the machine immediately and check the main bearing.
Check rotor clearance (requires professional repair if > 0.15 mm).
Check for loose pipes causing resonance.
03 Essential Emergency Tool Checklist (Recommended to Save)
Must-Haves in the Vehicle Toolkit:
1. Digital multimeter (for checking voltage).
2. Infrared temperature gun (for monitoring temperature).
3. Basic wrench/spanner set (M6-M24).
4. Spare pressure sensor (common models).
5. Emergency sealing tape (for emergency leaks).
