A build-up of moisture could be detrimental to your compressed air output. Regularly draining your receiver tanks will keep it clean and running smoothly. Regularly checking for any issues with the airend can help you to diagnose and fix a problem early on.Ĭheck your compressors hoses periodically to ensure they are not cracked or corroded, this could result in a leak which may reduce energy efficiency and ultimately cost you money.ĭrain condensation from air receiver tanks Factors such as overheating, poor lubrication, condensation and corrosion can cause damage to the airend which may result in malfunction or breakdown. Your airend should generally last around 44,000 hours if maintained correctly. Leak detection surveys can be carried out by expert aftermarket engineers who use ultrasonic leak detection technology to quickly and easily identify leaks in the system. Leaks in your system can drastically decrease efficiency and ultimately cost you money. Genuine OEM oil is always the best choice as it helps to maintain the integrity of your system and keeps your compressor running smoothly and efficiently. You should always ensure that you choose an oil that is the correct type for your installation. In injected screw compressors, oil plays an integral role. Many businesses will opt for an oil free air compressor compared to oil lubricated compressors as oil-free designs provide guaranteed clean air. In water-injected oil free compressors, water is used instead of oil to perform the same duties such as cooling and lubrication. This ensures that the air compressor output is completely oil free air. The male and female rotors do not touch and their positions are maintained through lubricated timing gears that are outside of the compression chamber. Coalescent filters can then be used to further reduce the oil quantity, resulting in a low oil carry over of around 2-5 ppm.Īn oil free air compressor, on the other hand, does not use any oil in the compression cavities. This will remove the majority of the oil through velocity changes. To remove oil from the final product, the compressed air leaves the airend and is passed through to an oil separator. The thermostatic valve also plays an integral role in maintaining the optimum temperature over a range of ambient temperatures by controlling the quantity of oil that is circulated to the oil cooler or the bypass. It is injected into the compression chamber to cool the machine, provide adequate lubrication of the moving parts, provide sealing and to aid with noise dissipation. In an oil injected rotary screw compressor, oil is used for four main purposes. It can, therefore, work at a high shaft speed and combine a large flow rate with small exterior dimensions. The screw element is not equipped with any valves and there are no mechanical forces to create any imbalance. The male rotor is normally designed with fewer lobes than the female rotor, this is so that it will rotate at a quicker speed, driving the female rotor. The male rotor has convex lobes and the female rotor has concave cavities. The two rotors are usually designed with different profiles. The pressure ratio of a screw is dependent on the length and profile of the screw and of the form of the discharge port. The main screw compression element parts comprise of a female rotor and male rotor that move towards each other while the volume between them and the housing decreases. This type of compressor is a positive displacement compressor and is the predominant type in use today. One of the most popular types of oil lubricated compressors is the screw compressor.
