When it comes to modern industrial machinery, the rotary screw compressor is one of the most widely used technologies. Renowned for their reliability and versatility, screw compressors are the workhorse behind many industrial processes and applications. This durable technology is suited to an array of demanding industry tasks, without which, businesses around the world would encounter operational challenges and efficiency problems.
There are two basic principles of compression in air compressors. One of these is the principle of positive displacement. There are a lot of compressor types that use this method, screw compressors being the most popular.
As the name suggests, rotary screw compressors use rotary movements to compress the air. Within the compressor, there is a set of male and female rotors. They will be designed differently so that, when turned in unison, air will become trapped between them. The male rotor has convex lobes and the female rotor has concave cavities; in this way, they can mesh together without touching to achieve compression. Additionally, the male rotor will have slightly less lobes than the female, meaning it will rotate more quickly, effectively driving the female rotor.
Unlike piston compressors which use the same principle of compression, the screw element is not equipped with valves. As such, it can work at a high shaft speed and there are no mechanical or volumetric losses to create imbalance. This means that screw technology can combine a large flow rate with a compact, space-saving design.
Single rotary screw air pumps are commonly used in a variety of applications such as pneumatic conveying, wastewater treatment, and food processing. They are also used in industrial processes to provide compressed air for power tools and machinery. Their simple design and reliable operation make them a popular choice for many different industries.
Single rotary screw air pumps are efficient, reliable, and easy to maintain. They operate quietly and with minimal vibration, making them suitable for use in environments where noise and vibration levels must be kept low. These pumps are designed for durability and can provide years of trouble-free operation. Their straightforward design allows for easy maintenance and access to internal components. Overall, single rotary screw air pumps are an excellent choice for a variety of industrial applications.
As the technology of choice across a wide range of applications, screw compressors have a lot to offer customers:
Continuous operation – Capable of continuous airflow and pressurisation, they don’t need to be shut on and off and have no duty cycle. This means that they can operate continuously with little to no downtime.
Easy to maintain – With very little moving and contacting parts, wear and tear are minimised. Long service intervals drive down maintenance costs and make any routine checks and repairs quick, easy, and hassle-free.
Powerful performance – Screw compressors can operate in challenging conditions as they have high airflow rates and can perform at extreme temperatures. This means they can run pneumatic tools and heavy equipment easily and efficiently.
Energy-efficient – Having stood the test of time, these durable machines produce less heat and conserve more energy than other models. These design features mean that they offer zero loss of capacity over time, keeping the lifetime cost of the compressor low.
Low noise – Quiet operation is down to the small size of the units and the lack of moving parts, making them suitable for point of use installations.
