The air compressor one-way oil cutoff valve (check valve) maintenance kit is a critical component for air compressor upkeep, primarily preventing reverse oil spray during shutdown to avoid compressor head seizure and other failures.
To determine if the air compressor oil cutoff valve requires replacement, conduct preliminary diagnosis using the following symptoms and steps:
1. Core Failure Symptoms
Oil Spray During Shutdown: Significant lubricant spray at the air inlet or oil-gas separator connection upon shutdown (normal operation should show no dripping).
High-Temperature Alarm: Rapid shutdown or high-temperature alarm after startup, potentially caused by reduced cooling oil flow due to valve blockage.
Abnormal Mechanical Noise: Unusual operational sounds, possibly indicating valve core wear or spring failure.
2. Quick Self-Diagnostic Steps
Check Oil Spray on Shutdown:
After shutdown, inspect the intake port or oil-gas tank connection. If oil drips exceed 50 drops per minute, replace immediately.
Check High-Temperature Alarm:
If high-temperature alarms trigger frequently, disassemble the oil cutoff valve to inspect for blockage or wear.
Test Electromagnetic Control:
If the oil cutoff valve uses electromagnetic control, check for coil damage or control circuit faults.
3. Replacement Recommendations
Regular Replacement:
Replace every 8,000 hours. Exceeding this interval may damage the spray head.
Prioritize Genuine Parts:
Avoid compatibility issues and ensure proper sealing performance.
Maintenance Environment:
Maintain good ventilation and heat dissipation. Keep away from volatile gases and debris.
If symptoms persist, contact a professional technician for further inspection.
