It is the most common type of AC worldwide, and many industries use it. The Operation of a Screw Type Air Compressor is relatively simple, with a screw usually mounted in a cylindrical case that rotates within a fixed casing. Air enters at one end and is drawn into matching spiral grooves outside the rotating member. The case is fitted with a valve that opens and closes when the power source turns the screw. The screw expels the air through a discharge nozzle, which may be located at the entrance of the compressing or suction chamber or at some intermediate point on the screw. For example, a suction nozzle may be located at the point where the pressure decreases as it travels through a space in which it acts as a pump.
Air power drives have been used since ancient times to drive pumps and pneumatic devices such as bellows.
Reasons To Consider Screw-Type Air Compressor
1. Cost Effectiveness
A screw air compressor is highly cost-effective as it requires less maintenance than other compressors. That makes it suitable for industries with fixed assets and less expensive than frequent repairs and compressor replacement. Moreover, since the frequency of repairs is less, the downtime from plant operation is also less. As a result, the personnel costs and operating costs are also reduced.
As it is a cost-effective solution, Screw Type Air Compressor has three major advantages over other air compressors.
The first advantage is flexibility.
The users can select several screw-type compressors according to their specific requirements, enabling them to optimize their investments’ use. That makes it an ideal option for planned up-gradation. Moreover, with this flexibility, one need not worry about finding space for new compressors as they do not take up much space in a plant or machine.
The second advantage is the extension of life.
As the equipment is usually well maintained and its maintenance consumption is relatively low, it can last a very long time because the compressor’s life is directly dependent on its technical specifications. Moreover, as this type of air compressor does not take much space, it can easily be upgraded to increase productivity or extend its working life by upgrading technical specifications such as an increase in pressure ratio from 3:1 to 4:1 or replacing the reciprocating piston with a rotary piston. That makes it a suitable option for planned up-gradation.
The third is security.
Since the working parts are protected from the environment, the unit remains secure for longer periods and does not need frequent maintenance compared to other air compressors. That reduces plant operation downtime, thus improving overall plant efficiency.
Screw Type Air Compressors are highly reliable as they are compact and weigh only a couple of pounds. The likelihood of a breakdown is very low because they have higher reliability owing to some safety features such as longer service life, lower unreliability, high resistance to wear and tear shock resistance, and simple maintenance requirements. That makes it an ideal option for planned up-gradation. Moreover, the more complex the internal parts of the compressor become, the higher its cost will be. That is why it is recommended to use simple parts such as screws instead of expensive ones such as valves and piston rods.
This air compressor is highly reliable and needs less maintenance than other compressors. It operates continuously for longer periods, making it a suitable option for industrial applications with high volume requirements, and it is less expensive than frequent repairs and replacement of compressors. Moreover, since the frequency of repairs is less, the downtime from plant operation is also less.
5. High Performance
A Screw Type Air Compressor is one of the most high-performing, as it does not have any lubrication problems and has an extremely long service life.
Screw Type Air Compressor has many advantages over the other types of compressors. It is suitable for industries with fixed assets as it requires less maintenance. It is also more cost-effective as it reduces downtime from plant operation, thus improving overall plant efficiency. Moreover, the flexibility in choosing various air compressors makes it an ideal option for planned up-gradation, and its simple internal parts, such as screws, make the compressor highly durable.
