Screw compressor in the woodworking industry
Compressor is one if important equipment needed in the woodworking industry. Compressor is the machine used to generate the compressed air as the energy sources in the woodworking process. According to the rotor inside there are 2 type compressor : the piston compressor and the screw compressor. In our previous posts: piston compressor for wood furniture we've reviewed about a piston compressor, now in this post we review the screw compressor.
Screw compressor is a compressor that uses the screws to suck and press the air. The 2 helical screws (they are also called as the rotor) mesh and screw to suck the air from the outside and compress it. There are 2 types of screw compressors that are: oil free screw compressor and the lubricated screw compressor. The lubricated screw compressor uses oil lubricant to wet the screws during they operate. The oil lubricated this will make the screw can work more efficient in sucking and squeezing the air, but the resulting compressed air will be mixed with the oil. The compressed air resulted then is filtered and separated from the oil. The air filtration generally is 2 times or more to ensure the resulting air to be oil free. The oil screw compressor is better in energy efficiency and it is the mostly used in the general industry, including the woodworking and furniture industry.
The second type is the oil free screw compressor, it is the screw compressor that does not use oil lubricant in it screw's. The air generated is relatively cleaner and oil free, but it has lower efficiency compared with oil lubricated compressor. This machine is more suitable for use as to supply the compress air to the industry which is very sensitive to the oil such as: medical research, the semiconductor industry, etc.
In general, the screw compressor is more stable, has smoother vibration, more compact and have higher energy efficiency compared to the piston compressors. The screw compressor has higher capacity then the piston comoressor. But this equipment has more expensive initial price then the piston compressors and also will need more electricity power. This machine is more suitable for use in woodworking industries requiring large-scale supply of compressed air in large quantities and continuously. Normally this machine also spend cheaper cost of maintenance compared with the piston compressor.
However, to obtain optimal benefits from the use of this machine we should be able to handle this equipment appropriately.
Here are the things that need to be considered in the uses of screw compressors
- Do the calculations to estimate volume of the compressed air needed.
- The proper maintenance
- The proper piping system.
