Product Description


Energy Saving Permanent Magnet Frequency Screw Air Compressor
Features:

it is unique new design, which combines the permanent magnet motor and the speed control frequency converter. it couples with the high-quality air end, which shows the advanced screw compressor technology, it can provide the unique energy-saving effect and super reliability. there is no motor bearing.the screw compressor is driven by the permanent magnet motor. there is no consider about the attrition of gear, pulley, belt, coupling, shaft seal and the moving parts, which leads to the leak or change parts, meanwhile, it not need to consider the calibration for the gear coaxial seal, the high-dffected converter technique will reduce the operationg costs prodigiously, which can provide you a real excellent technology.

HOW OIL-INJECTED ROTARY SCREW AIR COMPRESSORS WORK
As the name suggests, there is oil injected in this type of screw compressor. But where is it
injected, why and how? Let me explain..
As said before, the screw element is the most important part of the air compressor. But it
can't function by itself. There are a lot of other parts that make up the air compressor. 
How it works
Outside air
Air is sucked in by the screw element (air-end) through the air inlet filter. The inlet filter
makes sure that all the dust en dirt stays outside. It protects the screw element (which is
very expensive and can be damaged.
It's also the first step in making sure that the compressed air is clean: all the dust that is
sucked in will eventually end up in the compressed air system.
Load/unload control
Before the air enters the screw element, it passed the inlet valve or unload valve. This
valve opens and closes the air supply to the screw element.
When it's open, the compressor is in 'loaded' condition: it is actually compressing air and
pumping it into the compressed air system. When the valve is closed, is shuts off the air
supply to the compressor element: the motor and screw element are turning, but the compressor is not sucking any air in and is not pumping any air to the system.
