How Does a Refrigeration Screw Compressor Differ from Those That Use Pistons?
The Difference from The Type:
Refrigeration screw compressor and piston refrigeration compressors belong to positive displacement compressors.
Whereas a screw refrigeration compressor is a new high-speed refrigeration compressor with a self-lubricated transmission.
The Difference from The Principle:
The things that differ between the refrigeration screw compressor and piston compressor are their different operating mechanisms.
Specifically the difference in volume and compressed gas.
The difference is because both screw and piston compressors obtained operating volume is not the same.
Piston compressors are use piston that moves up and down, and the air is compressed.
It uses the crankshaft connecting rod mechanism and releases compressed air while the piston moves down by performing this principle repeatedly.
The working volume of the cylinder changes.
Screw compressors use a rotating helix which moves air in the chamber.
This movement is by centrifugal force when the air moves from the outside to the inside of the chamber.
These rotational cycles change the operating volume of a cylinder.
Differentiation from The Overall Structure:
A refrigeration screw compressor uses a rotating shaft attached to the pump, which forces air out of the pump and into the area.
It doesn’t have a piston, piston ring-like piston refrigeration.
But still screws types refrigeration compressor is compact structure, small size, lightweight, normal temperature, low cost, and good starting advantages.
There are other advantages for refrigeration screw compressor: save 10% to 100% power, with its a live valve.
As a refrigeration screw compressor manufacturer, Miracle also ensures high-quality spare parts that have a longer life without repair or maintenance.
Miracle also provides Copeland screw compressor, Bitzer screw compressor, semi-hermetic screw compressor, ammonia screw compressor, and Frascold screw compressor, which are very reliable and can go with your wide range of applications.
Miracle also supplies the lubricating oil for the refrigeration screw compressor, which increases its sealing and cooling performance.
You can even use the single stages for your many users because of its low evaporating temperature and high compression chance.
There is nothing significant to mention about this refrigeration screw compressor except its high noise for some disadvantages.
In general, the need to install muffling and sound insulation equipment, in the refrigeration compression, the need to spray add lubricating oil, thus requiring oil pumps, oil coolers, and oil recyclers, and other more auxiliary equipment.
In recent years, the development of the content of the volume ratio adjustable screw compressor, adjustable range of 2.6 ~ 5.
So that the performance of the screw compressor has been further improved.
Recently, the domestic development of a new semi-hermetic screw machine, the use of 5:6 asymmetric new tooth shape, so that the volume efficiency is greatly improved.
The new screw refrigeration compressor operating economy, reliability, and service life have exceeded the piston refrigeration compressor.
Therefore, the design and selection of refrigeration devices should be given full attention
