The Rotary Screw Air Compressor



The rotary screw air compressor produces an ongoing movement to generate power.For certain heavy-duty industrial operations, or a facility that needs to keep running their compressor 24/7 365 days a year, a piston compressor is considered insufficient. In order to get the pressure intensity needed for complex pneumatic and other high-powered tools, you will need to consider buying a rotary screw air compressor.

 

In a rotary screw compressor, air is compressed with a meshing pair of rotors. As the screws move in rotation, fluids gets sucked in, compressed and ejected.

So, how does an oil injected rotary screw compressor work?

AIR


The outside air is sucked in by the screw element (air-end) through the air inlet filter. The inlet filter makes sure that all the dust and dirt stays outside.

Load and unload control

 

Before the air enters the screw element, it passed the inlet valve or unloader valve. This valve opens and closes the air supply to the screw element.

When it’s open, the compressor is in ‘loaded’ condition: 

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.

WHAT DOES THE screw compressor element DO?

  

When the inlet/unloader valve is open, the air enters the compressor screw element.
The screw element works like a pump and it compressed the air. During this process, oil is injected in the element. The oil is there to cool the air, as the air gets very hot during compression. 

 

Compressed air/oil mixture

 

 

This mixture leaves the screw element through a one-way valve. This valve makes sure that the oil cannot flow back into the compressor element through the exit pipe.


WHAT IS THE PURPOSE OF THE OIL SEPARATOR?

 

It's job is to basically separate the oil and the air through the separator tank. Most of the oil is separated from the compressed air by centrifugal force . The remaining oil is separated by the separator element which looks exactly like a big filter.


The air with oil flows through the separator element and separates the oil from the compressed air. The separated oil is collected at the bottom of the separator and is removed by the scavenge line. It sucks the collected oil back to the compressor element.

WHAT IS THE MINIMUM PRESSURE VALVE?

 

 

The minimum pressure valve is a spring-loaded valve that opens at a certain pressure, about 2.5 bar. The minimum pressure valve makes sure that there is always a minimum pressure inside the compressor

The after cooler

 

The compressed air is still very hot, consequently the compressed air is now cooled by the after cooler before it leaves the compressor. The air temperature after the cooler is around 25 – 40 degrees Celsius.
Because of the cooling down of the air, a lot of water vapor has condensed against the inside of the after cooler. This water is carried with the compressed air towards the air outlet of the compressor.


Moisture trap

 

The condenstate trap (moisture trap) basically separates the water from the compressed air. The water is drained through a small hose.



Oil flow


The oil is cooled by the oil cooler. The amount of cooling is controlled by a thermostatic valve. If the oil is still cold, the oil cooler is completely by-passed. If the oil is very hot, all the oil is led through the oil cooler. 


 

The Oil filter

 

Finally, the oil flows through the oil filter. The oil filters removes all the dirt and dust that has collected in the oil.

air compressor oil


What Type Of Oil Are You Currently Using: Knowing what type or brand of oil you are currently using with your air compressor is very CRUCIAL to the performance of your compressor.  Compressors have a long life time and over that lifetime you may have filled it with different brands or types of oil.  Compatibility is key and knowing what type of oil is currently in the unit helps guarantee product compatibility.  Remember the old Pennzoil add on TV “PAY ME NOW OR PAY ME LATER”

 



 

air compressor oil




 

2. Viscosity Requirements:  Different types of compressors use different types of viscosities of oil. Rotary Screw Compressors generally use a 32, 46, or 68 viscosities.  Piston and Reciprocating Compressors generally use 100 viscosities such as (Teresstic ISO 100). Maintaining viscosity helps keep your air compressor running and lubricating, avoiding costly repairs and a costly shut down.

 

 

3. Performance: Always look for high performance oil. Excellent rust and corrosion protection, high oxidation stability, and a non-foaming formula.  DO NOT put motor oil into your compressor!!!!

AIR COMPRESSOR OIL







Not to sound redundant, but air Compressor Oil is designed to reduce carbon buildup in compressor valves to ensure a longer compressor life. The non-detergent, single viscosity, 30-weight oil provides the proper mix of lubricants for compressors for function properly and efficiently.

 

 

 

AIR COMPRESSOR OIL



 

Using the right air compressor oil for your compressor is very important. This is true for both rotary screw air compressors and reciprocating compressors. You can’t just use your cars oil or hydraulic oil!!!!! Compressor oil has a few important functions:



  • It removes heat from the compression
  • It works as a sealing to prevent air leakage.
  • It lubricates all moving parts
  • It’s used to cool important parts of the compressor element.

 

Air compressor oil is specifically designed to do the above jobs well. If you use oil from your car, your compressor WILL DIE!!

 

Compressors (and the oil) can get very hot.. normal maximum outlet temperature of a rotary screw compressor element is set at 120 degrees Celsius (if it gets hotter than this, your screw compressor will shut down).

 

Oil failure





AIR COMPRESSOR OIL

 





If you would operate your compressor on a too high temperature for a too long time, the oil will form a thin layer on the entire inside of your compressor (piping, compressor element, oil cooler). When this happens to your oil-cooler, it won’t be able to cool the oil as effectively as it used to. 

 

When this happens to your compressor, the ‘contaminated’ parts and especially the poor oil-cooler need to be chemically cleaned or replaced by new ones.

 

So it’s important to prevent this:
don’t let your compressor run too hot, and use the right kind of oil. Special compressor oil is designed to resist these high temperatures.  Contact H&K Pump in Dallas, Texas for service at: www.hkaircompressors.com

AIR COMPRESSOR OIL




How often do you change the oil in a compressor?

 

Typically, with a rotary screw compressor, you should change the oil every 7000 – 8000 hours that it has been used. For a reciprocating air compressor, you should change the oil every 3 months, ideally. It is important, however, that you change the oil at least once in a year.

AIR COMPRESSOR OIL




Can I use automotive engine oil in my air compressor?

 

 

AIR COMPRESSOR OIL


NO, NO, NO!!!! Auto engine oil contains detergents and other additives that can cause problems in compressors. In some cases, using car oil can cause a build up on both sides of the valves in your compressor pump.  This buildup will cause the compressor to run less efficiently and wear out faster because of the increased strain on the air pump.
