Common Questions Regarding Screw Air Compressor

Construction, home repairs, automotive, and similar industries require machines to run pneumatic machines. Since too much air pressure is required, operators use air compressors to run those machines. It simplifies their tasks and increases the efficiency of overall operations. Screw air compressors are among the powerful machines that wind up lots of tasks by applying air pressure to pneumatic machines. In just a few seconds, an operator can perform strenuous functions with the help of these compressors. Since many people use them in the construction and automotive repair industries, they have questions about them. Let’s answer those queries to deal with all the challenges professionals and beginners face. Are Screw Compressors Noisy? No, they are much quieter than you expect. Some are quieter than even a usual vacuum cleaner. Therefore, you can consider them quiet in places like a garage, construction site, etc. Since there are different types available in the industry. A screw compressor is less noisy than a piston compressor. The reason behind its quiet operations is the use of rotary screws inside it. They generate low noise in the air compression process.  If you look at the noise level, screw compressors generate 65 to 75 dba noise. It is much lower than the piston type, which produces 80 dba and higher. However, you must inspect a few things to see if your air compressor makes noise. There could be problems with the mounting, crankcase, and parts inside it. Otherwise, a screw air compressor does not make much noise. Is It OK To Leave the Air Compressor on All the Time? It is made to work for long hours, even 24/7. You can keep it turned on all the time without any worries. However, every machine has a life and needs rest. A screw air compressor can work for many hours without breaks, but it is better to turn it off for some hours. Since it is a machine, it has an internal motor that can overheat. Once it exceeds its temperature limit, its components could wear and tear.   Giving it some rest when not using it will be a good choice. That will save its oil, filters, motor, and other components from early replacement. Unnecessary motor movement will affect the life of the screw air compressor, and it could reach its limit earlier than you imagine. Its motor will get excessive strain, and electricity will be wasted. Besides, compressor oil will soon be contaminated because of excess usage.  How much heat does a screw air compressor generate? It does not generate too much heat if you look at its performance. Therefore, a screw air compressor can remain switched on for more than ten hours without any risk of overheating. If you compare it with other types, it generates less temperature than a piston air compressor. A screw air compressor generates below 200 F heat, which is almost half of the heat generated by a piston compressor.  How Many Hours Is a Lot for An Air Compressor? Every machine has an operating limit, which is also known as its life. When we talk about screw air compressors, it also has a limit. Since there are different types, each type has different lasting hours.  ✅ Piston air compressors could last 50,000 hours. ✅ Oil-Free rotary screw compressors could last 70,000 hours. ✅ Rotary screw air compressors have 100,000 hours of life. ✅ Centrifugal air compressors have 250,000 hours of life. What Is the Maximum Pressure for A Screw Compressor? There are two stages in the screw air compressor; single-stage and two-stage compressors. A single-stage screw compressor can generate up to 250 PSIG (17 bar) pressure. At the same time, a two-stage screw compressor can generate up to 600 PSIG (41 bar) pressure. What type of screw compressor is the most reliable? An oil-lubricated screw air compressor is the most reliable one. It can last up to 10 years, which is a good enough time to have a return on investment. In other words, it can last up to 100,000 hours because of oil lubrication. Oil reduced the friction to keep the machinery going against all the challenges like heat and pressure. Even if used 24/7, it could last 6 years or 50,000 hours. What Are Some Failures of Screw Compressors? Every machine faces problems at least once in its life. Likewise, a screw air compressor also faces some challenges in the form of failures. These failures occur either because of lack of maintenance or overheating. Seals, gaskets, and other components must be replaced frequently if the machine usage rate is high.  ✅ If it fails to reach maximum pressure, it is because the inlet or outlet pipe is blocked. ✅ Motor overloading failure is caused by clogged air filters or intake valve problems. ✅ Air filter problems could overheat the motor, so you must inspect it often.    ✅ Excessive oil consumption occurs because of high oil levels, blocked return pipes, or faulty oil separators. ✅ Oil leakage occurs because of a damaged oil seal. ✅ Startup issues occur because of electrical problems like broken cords, fuse, coil, and switch problems. ✅ If there is low air pressure, it is because of air leakage. ✅ Excessive noise and vibration occur because of bearing issues or loose components. ✅ If moisture is in the air, you must inspect its air dryer.   Can A Screw Compressor Be Serviced? Yes. A screw compressor can be serviced and periodic maintenance can help it to operate flawlessly and also maximize the service life. The structure of screw compressor consiss of several moving parts which usually become worn out with continuous usage. Periodic Maintenance ✅ Periodic Oil and Filter Changes: The oil serves as a lubricant and coolant in an oil-injected screw compressor. Oil changes at the recommended intervals are made to reduce mechanical wear and help maintain efficiency. Cascaded air, oil, and separator filter scheduling will also have to be adhered to. ✅ For Cleaning and Checking Coolers: When dust and dirt accumulate, coolers gradually become less effective at cooling. Cleaning will help avert the overheating conditions. ✅ Checking and Replacing Belts and Couplings: Drive belts and couplings are the means of transmitting power to the compressor and they will wear out. Periodically checking the signs of wear and tear and replacing when needed will prevent untimely breakdowns. ✅ Draining Moisture from the System: Because moisture accumulates in the system of the compressor, it causes corrosion. Therefore, the drain moisture collects regularly to have clean dry compressed air. ✅ Checking for Leaks and Abnormal Noises: Also checking hoses and pipes, and joints, with regard to leakages, vibration, and sounds can warn early for failure detection. Minor Repairs ✅ Air Leak Repairs: Compressed air leaks maximize inefficiency and raise energy payments. Locating and sealing the leaks will enhance performance. ✅ Replacing Worn-Out Bearings and Seals: Bearings and seals on shafts eventually wear; their replace- ment will avoid greater breakdowns. Intensive Repairs ✅ Air-End Cleaning/Replacement: The air-end-comprised of rotors and housing-is the heart of a screw compressor. If the performance is not up to the mark then cleaning becomes necessary ✅ Motor Overhaul or Replacement: The electric motor driving the compressor can wear. Rewinding or replacing brings back the efficiency. ✅ Control Panel with Sensor Replacement: Contemporary compressors with electronic control might need recalibration or replacement after some time.
