Advantages of a Screw Compressor
2014-8-11 Hits:[3016]
A rotary screw compressor is a air compressor which uses a rotary type positive displacement mechanism. Screw compressor technology has made significant improvements in recent years and now allows for improved performance levels. The simple and efficient design of rotary screw air compressors make them easy to maintain and operate, while providing great flexibility in the installation. There are many advantages in using a screw compressor.
Higher Specific Output
A British thermal unit (BTU) is the measure of energy needed to raise one CC of water a single degree celcius. A CFM is the measurement of the velocity of air out of or into a space. A main advantage of screw compressors is that they outperform other compressor types. A 65 CFM compressor with economized screws will yield about 134 percent specific output compared to a reciprocating compressor of 99 CFM. They also come in smaller overall sizes, which means savings of living or working space.
Less Moving Parts
The design and function of screw compressors is such that they have fewer moving parts than earlier reciprocating styles. The numbers of parts has been drastically reduced, due to new compressor technology, which features no rolling element bearings or valves. Another effect of the reduction in the total number of parts is the increased performance in the reliability rate of the compressor. Also improved is the expected life span of the compressor, and a reduction also in the maintenance factor.
Reduced Vibration
The design of the screw compressors is such that they are balanced to perfection without any reciprocating motion. Tests have demonstrated that vibration levels are brought down as much as 1/30th the levels often found in comparable reciprocating compressors.
Less Refrigerant Loss
The screw compressors have a reduced risk of suffering refrigerant loss due to the substantial decrease in vibration levels within the overall system. Refrigerant loss can occur as a result of any structural defects within the refrigeration unit. Less refrigerant loss is important as a factor in operations, due to the increased costs.
Other Advantages
Some of the other advantages of screw compressors are that they are designed to provide pulsation-free air. They also have reduced operating sounds and can be on continuous duty. Their energy efficiency is another attraction of screw compressors. So is the fact that they are energy efficient at capacity load and have longer service intervals. Screw compressors are designed to have a long life, improve the air quality and discharge lower temperatures than other comparable reciprocating compressors.
