In modern manufacturing, laser cutting technology has become one of the key technologies for high-precision processing , in order to ensure the efficient and stable operation of laser cutting, the role of auxiliary equipment such as laser-specific screw air compressors cannot be ignored. This article will introduce in detail how to use laser-specific screw air compressors correctly, covering their working principles, operating steps, and daily maintenance, to help companies better manage and maintain this key equipment.
1. Working principle and characteristics of laser-specific screw air compressor
1.1 Basic working principle of screw air compressor
Screw air compressor is a compressed air equipment widely used in industry. Its core component is a pair of intermeshing screw rotors. The screw rotor compresses the air to a higher pressure by rotating, and then transports it to the equipment that needs compressed air, such as laser cutting machine, through pipeline.
Compared with other types of air compressors,screw air compressors have the advantages of continuous operation, low noise, low vibration, high efficiency, etc., and integrate air storage, drying, filtration, and automatic drainage. It is easy to use and very suitable for laser cutting systems that require a stable air source.
1.2 Unique requirements for laser-specific screw air compressors
The laser cutting process has extremely high requirements for the quality of compressed air, especially in high-precision cutting tasks. The cleanliness and stability of compressed air directly affect the cutting quality. Laser-specific screw air compressors usually have the following unique features:
High cleanliness: During the laser cutting process, compressed air will directly act on the cutting area of the laser beam, so the air must not contain oil, water, and particulate matter. Laser-specific screw air compressors are usually equipped with high-efficiency filters and dryers to ensure that the output air meets high cleanliness standards.
High stability: Laser cutting requires stable compressed air pressure to ensure cutting accuracy. Laser-specific screw air compressors are usually equipped with a precise pressure regulation system that can maintain long-term stable output pressure.
Low noise design: In order to meet the requirements of modern factories for the working environment, laser-specific screw air compressors usually adopt a low noise design to reduce interference to operators and improve work efficiency.
2. Operation steps of laser-specific screw air compressor
2.1 Preparation before starting
Before starting the laser-specific screw air compressor, a series of preparations must be carried out to ensure the safe and stable operation of the equipment:
Check the power supply and line: Make sure that the power supply connection of the air compressor is normal, without short circuit, open circuit and other problems. Check the cables and terminals to ensure that there is no looseness or aging.
Check the oil level and cooling system: Before starting, it is necessary to check whether the oil level is within the specified range and ensure that the cooling system is operating normally. If the oil level is too low or the cooling system is abnormal, it needs to be replenished or repaired in time.
Check the air filter: Before starting, check whether the filter needs to be cleaned or replaced to ensure that the air cleanliness meets the requirements.
Environmental check: Check the surrounding environment before starting to ensure that there are no items that hinder the ventilation and heat dissipation of the air compressor, and keep the working area clean.
2.2 Correct startup and operation
Once the preparatory work before startup is completed, the screw air compressor can be started according to the following steps:
Start the air compressor: Turn on the power switch and start the equipment according to the operating manual of the air compressor.
Adjust the output pressure: According to the needs of the laser cutting machine, adjust the output pressure of the air compressor to the appropriate range.
Monitor the operating status: During the operation of the air compressor, the operator should regularly check the various operating parameters of the equipment to ensure that the equipment is working in a normal state.
2.3 Shutdown and maintenance operation
Shutdown operation is equally important and should be performed in the following steps:
Slow shutdown: After shutting down the laser cutting machine, gradually reduce the output pressure of the air compressor, and then shut down the air compressor power supply according to the operating manual. Avoid sudden power outages to prevent pressure fluctuations in the system and affect the life of the equipment.
Discharge residual gas: After shutdown, the exhaust valve of the air compressor should be opened to release the residual gas in the gas tank to prevent residual pressure from damaging the equipment.
3. Maintenance and care of laser-specific screw air compressors
3.1 The importance of regular maintenance
In order to ensure the long-term and stable operation of laser-specific screw air compressors, regular maintenance and care are indispensable. During the long-term operation of screw air compressors, parts will wear, oil quality deterioration, filter clogging and other problems will occur, which may lead to equipment performance degradation and even cause failures. Through regular maintenance, potential problems can be discovered and eliminated in time to ensure that the equipment is always in the best condition.
3.2 Key steps in maintenance and care
Lubricating oil replacement: The lubricating oil of the screw air compressor is the key to ensuring the normal operation of the equipment. The lubricating oil needs to be replaced regularly, usually every 2000-3000 hours of operation.
Air filter cleaning: Under normal circumstances, the air filter needs to be checked every 500 hours of operation and needs to be cleaned or replaced every 1000 hours. If the ambient air quality is poor, more frequent cleaning may be required.
Cooling system inspection: The cooling system of the screw air compressor is responsible for heat dissipation and ensures that the equipment operates within a suitable temperature range.
Electrical system maintenance: The electrical system of the screw air compressor includes motors, terminals, control panels, etc. Regularly check whether these components are loose, aging, short-circuited, etc.
Pressure regulation system calibration: Regularly calibrate the pressure sensor and regulating valve to ensure stable output pressure and avoid reduced cutting quality due to pressure fluctuations.
3.3 Troubleshooting and repair
During use, the screw air compressor may encounter some common faults, such as failure to start, increased noise, unstable output pressure, etc. When encountering these problems, a preliminary judgment should be made based on the equipment's fault code and operating manual. If you cannot troubleshoot the problem yourself, it is recommended to contact a professional technician for maintenance.
Conclusion: Strategies for efficient use of laser-specific screw air compressors
Laser-specific screw air compressors are one of the key equipment to ensure the stable and efficient operation of laser cutting machines. By deeply understanding its working principle, mastering the correct operating steps, and performing regular maintenance, you can maximize the life of the equipment, improve production efficiency, and ensure high-quality output of the laser cutting process.
