Oil-free air compressor use note

The oil-free air compressor is the main body of the air source device. It is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy, and is a pressure generating device for compressed air.

Oil-free air compressor use note

1. When the oil-free air compressor is shut down due to power failure, in order to prevent the compressor from starting up under pressure, the power-off handle of the pressure switch should be pulled to drain the air in the pipeline and restart the compressor.

2. The user must set the compressor protective grounding wire to ensure that all metal shells of the compressor are in good contact with the earth, and the grounding resistance should meet the national standards.

3. The oil-free air compressor should stop running immediately when it finds serious air leakage, abnormal noise and peculiar smell, and can only run again after finding out the cause and troubleshooting.

4. The oil-free air compressor is an oil-free air compressor, and the friction parts are self-lubricating, so do not add lubricating oil.

The oil-free air compressor must be fixed on a ventilated, stable and solid working surface. In order to reduce noise and vibration, there must be a shock absorber.

6. The filter medium (foam sponge or felt) in the filter should be cleaned every three months, blowing off the dust on the medium, if necessary, wash with water, dry and reuse.

7. The oil-free air compressor shall be maintained at least once a quarter. The maintenance contents include thoroughly removing dust and dirt from the outside of the compressor, checking and fastening the connecting bolts of the compressor, checking whether the grounding wire is in good condition, and checking whether the electrical circuit is aging or damaged.

The oil-free air compressor is a miniature reciprocating piston compressor. When the crankshaft of the compressor is driven by a single shaft of the motor, the piston with self-lubrication without adding any lubricant will reciprocate through the transmission of the connecting rod. The working volume formed by the cylinder wall, cylinder head and piston top surface will change periodically. When the piston of the piston compressor starts to move from the cylinder head, the working volume in the cylinder gradually increases. At this time, the gas enters the cylinder along the intake pipe and pushes the intake valve open until the working volume becomes the maximum. So far, the intake valve is closed; when the piston of the piston compressor moves in the opposite direction, the working volume in the cylinder is reduced and the gas pressure rises. When the pressure in the cylinder reaches and is slightly higher than the exhaust pressure, the exhaust pressure, the exhaust pressure, until the piston moves to the limit position, the exhaust valve is closed. When the piston of the piston compressor is again moved in the reverse direction, the above process is repeated. That is: the crankshaft of the piston compressor rotates once, the piston reciprocates once, and the process of air intake, compression, and exhaust is successively realized in the cylinder, which completes a working cycle. The structural design of single shaft and double cylinder makes the gas flow rate of the compressor twice that of the single cylinder at a certain rated speed, and the vibration and noise control is well controlled.

It refers to the parts that have clear service life requirements in the planning and need to be replaced when the B maintenance expires, otherwise it may cause serious harm to the unit or system. For example, the air filter element, oil filter element, oil and gas separation core used in the air compressor unit are all special oils, as well as the oil and dust removal filter element and adsorbent on the compressed air purification equipment.

oil-free air compressor filtration function: filter metal particles and impurities in the special oil for air compressor to ensure the cleanliness of the circulation system and maintain the operation of the host. Generally 2000 hours, can be adjusted according to environmental conditions. Oil filter clogging alarm set value is generally 1.0-1.4bar

hazards of overdue operation: short oil return time, high exhaust temperature, short service life of the oil core; stable and short host, shortened service life of the host; unfiltered oil containing metal particles and impurities enters the host after the filter element is damaged, Causing serious consequences of host damage.

Oil-free compressor air filter function: air filter is an important maintenance barrier for air compressors! Filter the dust and impurities in the air sucked by the air compressor. The cleaner the inhaled air, the better the service life of the oil filter element, oil and gas separation core and oil. Avoid other foreign objects from entering the host, because the components of the host are matched, and the important matching space is generally 30-150μ, so the foreign objects entering the host will definitely cause harm and cause the host to lock up and fail.
