How the screw compressor works
The airend in screw compressors, as we said, consists of two rotors that work against each other. These rotors trap air between them and compress it. This compression increases the temperature and pressure of the air. In piston compressors, there is a cooling system consisting of a radiator and a fan, which reduces the temperature of the compressed air. This compressor works in a reciprocating manner and moves through the pistons inside the cylinder and compresses the air. . For the correct operation of piston compressors, this device should be used intermittently, especially in the hot seasons of the year.
8 The main difference in the screw compressor with the piston
Let's compare these two compressors in terms of how they work, energy consumption, maintenance, repair costs and other factors:
The difference of the sound of the piston compressor and the screw
One of the features that is very important in the use of compressors is the sound of the compressor. The high noise of the compressor causes distraction for the employees in the work environment. In this case, we must say that due to the friction between the parts of the piston compressor, the noise of this device is much higher than that of the screw compressor. The screw compressor has more advanced technologies and therefore will produce less noise.
Compare Piston and Screw Compressor in terms of performance
The screw compressor often has the ability to work continuously, with the difference that the piston compressor is usually used for small industries and workshops that do not need continuous use of compressed air, because the piston compressor cannot work continuously.
The useful life of compressors
It is better to know that the lifespan of screw compressor parts is longer than that of piston compressors and they will last almost twice as long as piston compressors. When we talk about useful life, it means how healthy they stay in standard mode, but in both types, there are compressors that have lived for more years. Also note that changing the screw and piston compressor oil and their timely service will have a direct effect on increasing the life of the compressor.
Screw and Piston Compressor Price Disagreement
Keep in mind that it costs more than the price. Because the piston compressor is structurally simple and thus has a lower price. Of course, buying each model of compressor can be different depending on the budget of people, but buying a piston compressor is often more economical.
Cost Difference in Repair Each compressor
In this case, we should also say that due to the more complex and modern structure of the screw compressor, its repair cost is also higher than that of the piston compressor. But pay attention to this point. Timely service of compressors can help reduce the cost of repairing them.
Difference in the capacity of compressors
One of the important aspects in choosing a compressor is the capacity of the compressor. Often the capacity of screw compressors is higher in producing pressure, which is due to their helical structure. On the other hand, piston compressors have the capacity to create less pressure.
