Which is best Rotary compressor or reciprocating compressor?

Receip or Piston type compressor are used for large duty cycle work (A/c or other equipments), energy hungry but last longer (Heavy Duty). Where as rotary compressor are energy efficient with higher ( Energy Efficiency Ratio) but lower duty cycle and shorter life. Selection of compressor are based on the nature of application. Normally, for room A/Cs with capacity less than 3 ton, most companies offer rotary compressor due to it's EER and less duty cycle. For heavy duty A/Cs, recip or piston compressor best suited.


Can you take a horizontal air compressor and use it vertically?

What kind of air compressor is it? And if it is oil lubricated no!


What does a pneumatic system consist of?

A basic Pneumatic system can contain simply 3 things: - An air supply (compressor) - A 3/2 valve - A single acting cylinder. This is a simple system that will open and close something when a button is pressed/released.


Can you use a reciprocating compress replace a scroll compressor?

A reciprocating compressor is basically a piston pump, much like if you'd take an average internal combustion engine and force it to run. A scrolling compressor uses two plates with a spiral-wound raised ledge on them. The ledges overlap and as they move in relation to each other air gets squeezed further and further into the labyrinth until it reaches the outlet port.


What is stall in axial flow compressor?

This type of compressor moves air by the use of rotating airfoils countered against static (nonmoving) airfoils. All airfoils are designed to move air "downward", or rearward in a jet engine. Since the purpose of a compressor is to compress, conditions can sometimes develop where the airfoils try to compress more than their design. Air begins to try to flow backwards to relieve the excess pressure. This backpressure is the same as an airplane wing increasing it's angle of attack (say by flying too slowly). The airfoil can't move enough air to maintain the pressure and the result is a stalled airfoil. Modern jet engines will bleed air out the middle or back of such a compressor to prevent such stalls. Early jet engines had no such protections. A stalled compressor is actually easier to turn. This relieves the load on the turbine powering the whole thing and the engine overspeeds. The pilot sees a surge in the engine. If it overspeeds enough, catastrophic damage may occur to the turbine (it explodes). The compressor bleed lines help prevent such failure.

Why you cant have a centrifugal switch in a hermetic motor?

The hermetic compressor cannot use a centrifugal switch like an open motor because it will disrupt the start winding. Hermetic compressors work through insulated motor terminals, and not in the open.

What is the hermetic motor?

Hermetic motors are motors used in hermetic compressors. Hermetic motor use wound stators and squirrel cage rotors, without shaft bearings and have a relatively tight design.


What types of workshop tools require an air compressor?

Some tools that may require an air compressor are wrenches. Some wrenches will operate on air power for faster use.


Use hermetic in a sentence?

When i bought new containers, they were very hermetic. Although the bedroom window was not actually painted black, the sash was permanently closed against the possibility of any air entering the room by an almost hermetic seal of duck tape.


What size air compressor is needed to run an impact wrench?

It depends on the wrench. Most impact wrenches available for homeowner use require a compressor that can maintain 85 psi under use. Usually these are the wheeled compressors with at least a 15 Gallon tank. -I have a small 2 gallon compressor that works for most things, but an impact wrench will empty the tank in about 15 seconds - so I need a bigger compressor or tank combo to operate that.


What is the difference between air compressor filters and air compressor air dryers?

Air compressor filters are on the intake side of the compressor motor to filter the air as it is brought in. Dryers are collection points that are drained daily as the compressor is hot when operating and moisture develops in the tank. Should drain the tank daily after use and the dryer should be installed in line before the gun.
