How To Refuel The Air Compressor? What Precautions?

Air compressor oil is indispensable for the operation of screw air compressors, just like a car cannot be without oil, and fish cannot be separated from water. Screw air compressors are widely used in many industries, and their corresponding air compressor oils have higher quality requirements. Therefore, in many cases, professional oils can better meet the requirements of such compressors, making the compressor in the working process. Improve the corresponding efficiency.

If you want to ensure the normal operation of the screw air compressor, the advanced thing you need to pay attention to is to check the air compressor oil in the machine regularly. If you need to add new air compressor oil, you must add it in time.

In the operating state of the air compressor, the oil level of the air compressor should be kept between the two red lines of the oil level sight glass (the pointer of the pointer oil level gauge is in the green position). More oil will affect the separation effect, and less oil will affect the lubrication and cooling performance of the machine, during the oil change interval, if the oil level is lower than the less oil level, the lubricating oil should be added in time.

Replenishment method:

Stop the compressor.

Disconnect the compressor air outlet pipe from the air pipe network, and drain the pressure inside the air compressor.

Cut off the power supply and disconnect the compressor from the main power supply.

After ensuring that the machine has no internal pressure, open the oil filler port on the oil tank and add a proper amount of lubricating oil to the oil tank.

Screw on the screw plug and wait for 3-5 minutes. Observe the oil mark, the oil level should be kept between the two red lines of the oil level sight glass.

Fill in the refueling record.

Precautions:

Oil replenishment must be carried out when the machine is stopped and without internal pressure.

Lubricants of different brands and different manufacturers cannot be mixed.

In addition to regular oil checks and refills, it's worth noting that advancements in compressor technology have introduced the option of oil-free air compressors. These compressors are designed to operate without oil, making them ideal for applications where completely oil-free air is essential, such as in the medical, food, and electronics industries. Unlike traditional screw air compressors that rely on oil for lubrication and cooling, oil-free compressors use alternative materials and coatings that reduce friction and wear, allowing for efficient operation without the need for oil.

However, screw air compressors with oil still remain a popular choice in various industries due to their robust performance and reliability. Proper maintenance of the air compressor oil, such as regular replacements and ensuring the correct oil level, can significantly prolong the lifespan of the equipment. For instance, running a compressor with insufficient oil can nice to overheating, increased friction, and potential damage to internal components. On the other hand, overfilling can cause excessive pressure, pilot inefficient air and oil separation, and possible damage to the separator filters.

To prevent such issues, it’s essential to establish a regular maintenance schedule. This should include periodic oil analysis to check for contaminants or degradation, as well as timely oil changes according to the manufacturer's recommended intervals. For operations where a no-oil air compressor is feasible, the maintenance requirements may be reduced, although periodic checks and upkeep are still important to ensure the machinery functions smoothly.

Each type of compressor has its own advantages and is suited to different applications, so choosing between an oil-lubricated screw air compressor and an oil-free air compressor should be based on specific needs and operational requirements. Both options can deliver reliable compressed air solutions when properly maintained and managed.
