Main part of Screw Compressor is Air-end, consisting of a pair of rotors. The male motor is driven by electric motor. Suction of air though Inlet filter and suction control valve. Air oil mixture from air-end flows into an air oil separator. The separated oil flows through oil filter and after cooling in 'cooler', it gets back into the system. The air also passes through air cooler and to the receiver. The whole system is controlled through valves / sequence of compressor is done through electric /electronic control.What is a screw type air compressor?Indo-Airs rotary screw air compressors serve as the backbone of a wide range of industrial applications. The principle of the rotary screw air compressors are made from high-end designs, innovative features, and technologies to provide cost-effective, long-lasting, dependable, and premium compressed air solutions for light to heavy-duty industrial applications.Rotary screw air compressors are high-efficiency rotary positive displacement machines that can operate at high speeds over a wide range of operating pressures and flow rates. There are no valves or other mechanical forces that can induce unbalance in screw air compressors. This permits a compressor to run at high speeds while delivering a huge flow rate in a tiny package. The fundamental benefit of employing a rotary screw air compressor is that it can continuously produce compressed air with little delivery pressure fluctuations and generates less heat than traditional air compressors, resulting in energy efficiency.How does a screw type air compressor work?Within the casing of a rotary screw air compressor, two interlocked helical rotors rotate in opposite directions. Ambient air is drawn into the compressor and circulated through the intended valve, where it is confined between the two helical rotors. As the screws turn, the pressure rises as the air volume decreases. Inside a rotary screw air compressor, Lysholm screws can be found.Air compressors, in many circumstances, will have the full power of two screws, which is necessary for many large-scale productions. Some rotary screw air compressors only have one screw and are only used for refrigeration in rare cases.What is the working principle of the rotary screw air compressor?The rotary screw compressor is one of the most extensively used technologies in modern industrial machinery. Screw compressors are the workhorse behind many industrial processes and applications, thanks to their dependability and versatility. This long-lasting technology is well-suited to a variety of demanding industry operations, without which organisations all over the world would face operational difficulties and inefficiency.In air compressors, there are two primary compression concepts. The principle of positive displacement is one of them. This technology is used by a variety of compressors, the most common of which being screw compressors.Operating PrinciplesA set of male and female rotors are located within the compressor. They'll be built differently such that when they're all twisted at the same time, air gets trapped between them. The male rotor features convex lobes, while the female rotor has concave chambers, allowing them to mesh without touching and achieve compression. As the male rotor has fewer lobes than the female, it will rotate faster, thus driving the female rotor. Unlike piston compressors, which use the same compression concept, the screw element does not have valves. As a result, it can operate at high shaft speeds without causing instability due to mechanical or volumetric losses. Screw technology may therefore combine a high flow rate with a small, space-saving design.What are the benefits of rotary screw air compressors?Screw compressors, being the technology of choice for a wide range of applications, have a lot to offer customer including:Continuous operation - They don't need to be turned on and off, and they don't have a duty cycle because they can provide continuous airflow and pressurisation. This implies they can run indefinitely with little to no downtime.Easy to maintain - Wear and tear are minimised because there are very few moving and contacting parts. Long service intervals save maintenance expenses and make routine inspections and repairs simple, quick, and painless.Powerful performance - Screw compressors have high airflow rates and can perform at extreme temperatures, allowing them to operate in difficult environments. This implies they can readily and efficiently operate pneumatic tools and big equipment.Energy-efficient - These long-lasting machines emit less heat and use less energy than other models since they have endured the test of time. Because of these design qualities, there is no capacity decrease over time, lowering the compressor's lifetime cost.Low noise - The quiet operation of the devices is due to their tiny size and absence of moving parts, making them ideal for point-of-use installations.Are screw compressors better?To understand which one is better, the following comparison can be helpful - Screw air compressor -A constant supply of airIncreased duty cycleBetter long-term durabilityIncreased overall effectivenessReduced background noiseAirflow per rated power is higher.Reciprocating air compressor -Extremely high pressure demandsSpare parts managementReduced duty cycleWhat is the difference between the reciprocating compressor to a screw type compressor?The mechanism by which Rotary Screw Air Compressors and Reciprocating Air Compressors compress air differs significantly.Their distinguishing characteristics can be summed up as follows:System designFor compressing the input air, rotary screw air compressors use a pair of meshing spiral screws known as rotors. For compressing the air, reciprocating air compressors use pistons that are moved by a crankshaft.Components involvedScrew air compressors are not vulnerable to significant wear and tear because they only have two moving parts (screws) with a little space between them. Even in versions where the two screws come into contact with one another, there is little friction, therefore they are less prone to break down. Reciprocal air compressors, on the other hand, contain more moving parts, such as pistons, piston rings, connecting rods, and inlet-outlet valves, which makes them noisier and necessitates spare parts storage.TemperatureScrew air compressors generate between 80 and 99 degrees Celsius of internal heat during use. Because there is no friction between the screws, heat production is reduced. With the help of a thermostatically controlled fluid circuit, the oil or lubricant employed between the rotors and casing forms a non-wearing seal that can eliminate the heat. The pistons of reciprocating air compressors operate at temperatures ranging from 150 to 200 degrees Celsius. The friction created by the movement of piston rings against the cylinder walls causes the high temperatures.Oil filtrationBecause this machine features a three-stage oil filtering system, the chances of finding leftover oil in an oil-lubricated screw air compressor are quite slim. Typically, the oil concentration is less than three particles per million (PPM).However, because a reciprocating air compressor lacks an oil filtration mechanism, the air it produces can be more contaminated than that produced by a screw air compressor. When piston rings and oil rings deteriorate, oil can flow up to the compression side, increasing the oil concentration in the air.Air-receiver tanksWhen using a rotary screw air compressor, determining the right size of an air-receiver tank might be difficult because most of the connected applications don't require one. This machine is designed to deliver a constant stream of compressed air with no pulsation or interruption. You won't need a tank if the airflow needs of your tool is smaller than what the air compressor can provide. Piston-based compressors, on the other hand, have air-receiver tanks that store air and reduce pulsation before running the linked applications. Once the tank is filled, the equipment can be used.Industries that use rotary screw air compressorsScrew compressors are used by many industries to increase their daily production capacity. Due to their strong design diagram and lack of a duty cycle, they are well-suited to heavy-demand industrial activities. Manufacturing sectors such as automotive, brewing, food packaging, aerospace, construction, beverage, and textile all benefit from screw air systems. Because they can withstand a wide range of working circumstances, they are appropriate for both small and large-scale operations as well.Rotary screw air compressors are driven by two counter-rotating screws. They're usually quieter and more effective than piston engines. Rotary air compressors are Utilized when huge amounts of high-pressure air are required on a daily basis for around 8 hours. Rotary screw air compressors also have extended lifespans, making them an excellent long-term investment. Because there is no metal-to-metal contact, there is less wear. Finally, these systems are generally easy to maintain.
