Longxin Four-in-One Air Compressor: Function and Composition

Screw Air Compressor Main Unit

As the core component, it employs

direct drive transmission (non-belt),

offering higher transmission efficiency

and reduced maintenance requirements.

It provides a continuous and stable

air supply, forming the foundation

for the entire system's reliable operation.

Air Receiver

Primarily serves to stabilise pressure and provide buffering,

capable of storing compressed air

to balance pressure fluctuations.

Simultaneously, it performs preliminary separation

of liquid water from compressed air,

reducing the burden on subsequent processing stages.

Refrigerated Dryer

Its function is to cool compressed air

to the dew point temperature, thereby

removing the majority of water vapour,

rendering the compressed air drier

and meeting the humidity requirements

for laser equipment.

Precision Filter

Features multi-stage filtration

(C/T/A grade) functionality,

effectively removing impurities

such as dust and oil mist.

Through multi-stage filtration,

it meets the stringent air quality

requirements of laser equipment,

delivering clean compressed air.

Longxin Four-in-One Air Compressor Functions

Stable Pressure

This four-in-one air compressor delivers compressed air at a stable pressure of 15kg/cm² for laser cutting/welding equipment. Consistent pressure ensures precision in cutting and welding operations.

Dry Air

Processed through a refrigerated dryer, it removes most water vapour, supplying dry compressed air to laser equipment. This prevents moisture-related equipment failures and processing quality issues.

Clean Air

Multi-stage filtration through precision filters removes impurities such as dust and oil mist, meeting the stringent air quality requirements of laser equipment. This delivers clean compressed air for laser cutting/welding, safeguarding normal equipment operation and processing outcomes.

Pre-startup checks

Check the oil level

Ensure the oil level is near the centre line of the sight glass.

An appropriate oil level is fundamental to the air compressor's normal operation.

For instance, if the oil level is too low, it may lead to insufficient lubrication, affecting the equipment's service life.

Drain Condensate

Drain condensate from beneath the air receiver, refrigerated dryer, and filter to prevent accumulation that may impair equipment performance. Excessive condensate may lead to rusting, corrosion, and other issues.

Inspect for oil and gas leaks

Thoroughly examine for any visible oil or gas leaks,

promptly identifying and addressing such issues to prevent

energy wastage and potential safety hazards.

Operational Monitoring

Monitoring Control Panel Parameters

Keep a close watch on control panel parameters such as pressure, temperature, and current to ensure they remain within normal ranges. For instance, abnormal pressure readings may indicate blockages or leaks within the equipment.

Listen for operational sounds

Listen carefully for operational sounds to determine whether any abnormal knocking or scraping noises are present. Such unusual sounds may indicate loose or worn internal components within the equipment.

Smell for odours

Check for any burnt smell indicating overheating. A burnt smell may signal equipment overheating or an electrical fault, requiring prompt investigation.

Post-shutdown procedures

Drain condensate again

Drain condensate again if necessary to ensure no excessive water accumulates within the equipment, thereby further protecting it from condensate damage.

Clean machine surfaces and surroundings

Clean the machine surfaces and surrounding environment, maintaining good ventilation. Adequate ventilation aids heat dissipation and extends the equipment's service life.
