Laser Cutter Air Compressor Failure and Maintenance Analysis

If an abnormal phenomenon occurs during the operation of the laser cutter air compressor, the cause of the fault must be found out immediately, the fault must be eliminated immediately, and it can only be used after repair. Do not continue to use it blindly, resulting in unpredictable losses.

Common faults of laser cutter air compressors

1. High Temperature Fault Shutdown

• Causes

Inferior oil or poor oil products, lack of oil; oil filter blockage or oil circuit obstruction; fan motor failure (contactor failure); air filter blockage; temperature sensor failure; poor cooling of the cooler or blockage of the heat sink; temperature control valve failure; host damage.

• Maintenance Method

Check the cooling system to ensure that the flow of the coolant is normal and check whether the cooler is blocked.
Check whether the cooling fan is operating normally, clean the fan and heat sink.
Detect the ambient temperature to ensure that the temperature of the working environment of the air compressor is within the specified range to avoid the impact of high temperature environment on the equipment.
Check the lubricating oil, check the oil level and oil quality of the lubricating oil, and replace the lubricating oil if necessary.

2. The Laser Cutter Air Compressor Consumes a Lot of Oil

• Reason

High non-exhaust oil content, lubrication pipeline leakage or seal failure; high oil content, whether the return oil pipe is unobstructed; oil level is too high; long-term low-pressure operation; oil failure; oil emulsification or deterioration; precision filter failure; loading and unloading are too frequent.

• Maintenance Method

Replace the oil separator core. If the oil consumption increases due to the blockage of the oil separator core, the oil separator core needs to be replaced in time.
Adjust the oil level. If the oil consumption increases due to the high oil level, the oil level needs to be adjusted in time.
Lower the oil temperature. If the oil consumption increases due to the high oil temperature, the oil temperature needs to be lowered in time. When lowering the oil temperature, measures such as increasing the heat dissipation area and increasing the ventilation volume can be taken.

3. Electrical Failure

• Reason

Whether some electrical appliances are working properly (high voltage, low voltage, poor contactor); motor failure; poor contact of the power switch.

• Maintenance Method

Replace damaged components; clean oxidized contacts; tighten loose wiring; adjust control system parameters.

4. Abnormal Shutdown of Laser Cutter Air Compressor

• Reason

Non-overload shutdown, high temperature shutdown, power failure, loose wiring, circuit relay or safety failure. Overload shutdown, high exhaust pressure, thermal relay failure, increased lubricating oil viscosity, main motor failure, loose motor or contactor connection, main engine failure, small set value.

• Maintenance Method

Replace damaged components; tighten terminal blocks; clean oxidized contacts; adjust control system parameters; clean cooling system; replace damaged fans

5. The Air Compressor Does not Start

• Reason

Power failure, power cord broken, voltage unstable or power switch damaged.
Control circuit failure: relay, contactor or controller in the control circuit is damaged.
Motor failure: motor winding burns or motor bearing is damaged.

• Maintenance Method

Check and repair the power line to ensure stable voltage.
Check the control circuit and replace damaged relays, contactors or controllers if necessary.
Check the motor and repair or replace damaged motor parts.

6. Air Compressor Overheating

• Reason

Cooling system failure: insufficient cooling water, cooler blockage or cooling fan damage.
Lubrication system failure: insufficient lubricating oil or lubricating oil pump failure.
Ambient temperature is too high: the working environment temperature is too high, resulting in poor heat dissipation of the air compressor.

• Maintenance Method

Check the cooling system, add cooling water, clean or replace the blocked cooler, repair or replace the cooling fan.
Check the lubrication system, add lubricating oil, repair or replace the lubricating oil pump.
Improve the working environment, lower the ambient temperature or strengthen ventilation.

7. Insufficient Output Pressure of the Air Compressor

• Reason

Intake filter blockage: The intake filter is blocked by dust or impurities.
Exhaust valve failure: The exhaust valve is poorly sealed or damaged.
Pipeline leakage: There is a leak in the gas pipeline of the laser cutter air compressor.

• Maintenance Method

Clean or replace the intake filter to ensure smooth air intake.
Check the exhaust valve, replace the seal or damaged exhaust valve.
Check the pipeline, repair or replace the leaking pipeline.

8. Abnormal Noise in Air Compressor

• Cause

Loose mechanical parts: The mechanical parts inside the laser cutter air compressor are loose or worn.
Bearing damage: The bearings of the air compressor are worn or damaged.
Foreign matter entering: Foreign matter enters the inside of the air compressor, causing friction between parts.

• Maintenance Method

Check and tighten loose mechanical parts, and replace worn parts if necessary; Check the bearings, lubricate or replace damaged bearings; Check and remove foreign matter inside the air compressor.

Precautions

Before performing any maintenance or repair, be sure to disconnect the power supply to ensure safety.
Use appropriate tools and accessories and avoid using inappropriate materials.
Regularly record the maintenance and repair conditions for subsequent tracking and management.

Air compressor maintenance measures

In order to reduce the occurrence of air compressor failures, regular preventive maintenance is essential. The following are some common preventive maintenance measures:

1. Regularly check and replace the filter

The air intake filter and oil filter are easily clogged with dust and impurities after long-term use, affecting the normal operation of the laser cutter air compressor. It is recommended to check and replace the filter regularly to ensure smooth air intake and normal operation of the lubrication system.

2. Regularly check the lubrication system

The lubrication system is an important guarantee for the normal operation of the air compressor. Regularly check the oil level and oil quality of the lubricating oil, and replenish or replace the lubricating oil when necessary. At the same time, regularly check the lubricating oil pump and oil circuit to ensure the normal operation of the lubrication system.

3. Regularly clean the cooling system

The cooling system is prone to accumulate dirt and scale after long-term use, affecting the heat dissipation effect. It is recommended to regularly clean the cooler and cooling water pipeline to keep the cooling system in good condition.

4. Regularly check the mechanical parts

The mechanical parts of the laser cutter air compressor are prone to loosening and wear during long-term operation. It is recommended to regularly check the tightness of the mechanical parts and tighten and replace them when necessary.

5. Regularly check the electrical system

The electrical system is the control center for the normal operation of the air compressor. Regularly check the working status of the electrical circuit, controller and motor to ensure the stability and reliability of the electrical system.

Summary

Regular maintenance and timely repair of laser cutter air compressors are important guarantees to ensure their efficient operation. By following the above guidelines, the service life of the equipment can be effectively extended, the failure rate can be reduced, and work efficiency can be improved.
