What is a pilot valve on an air compressor?
The pilot valve opens, actuating the unloading device and allows the compressor to run in an unloaded mode. When the receiver pressure drops to the preset cut-in pressure, the pilot valve closes allowing the unloading device to close and the compressor once again pumps into the receiver.
Why does my air compressor keep shutting off?
If your air compressor trips off the moment it powers on, the issue is likely caused by trapped air over the pistons. To test for this problem, shut off the tank, unplug it from the power supply and drain the tank of all air.
Intake Stroke
During this first step, air and fuel get into the compression chamber via the open intake valve. Next, the calibrator regulates the amount of both components released to ensure that the correct mix of air and oil gets into the system.
Compression Stroke
As this second step starts, the inlet valve closes. By minimizing the available space within the fuel cylinder, the piston compresses the moisture of air and fuel within the cylinder.
Expansion or Power Stroke
The spark produced at the end of the compression stroke lights up the mixture, which causes combustion. That explosion forces the piston to the engine cylinder’s bottom. The combustion changes the fuel into mechanical energy that powers the machine.
Exhaust Stroke
This is the final step of the process, and it involves eliminating the waste products of the whole process. Exhaust naturally occurs as a combustion byproduct, and it should be expelled from the engine. During this step, the exhaust valve opens and forces the piston to push the exhaust from the engine.
Cooling
It is natural for compressed air to generate heat, so cooling is essential to keep the engine from overheating. The common cooling methods used in air compressors are:
Oil Filtering
The majority of rotary screw gasoline air compressors are generally oil-injected. This is because they depend on oil to lubricate the machine, but they have to filter and separate the oil from the air before removing the air from the machine.
How does an air compressor work?
Air compressors work by forcing air into a container and pressurizing it. Then, the air is forced through an opening in the tank, where pressure builds up. Think of it like an open balloon: the compressed air can be used as energy as it’s released.
How does a centrifugal compressor work?
Centrifugal, or radial compressors, work by bringing air into the center through a rotating impeller, which is then pushed forward through centrifugal, or outward, force . By slowing the flow of air through a diffuser, more kinetic energy is generated.
How many screws does a rotary screw compressor have?
Rotary screw compressors have two internal “screws” that rotate in opposite directions, trapping and compressing air between them. The two screws also generate constant movement as they rotate around. This is a common type of air compressor and is one of the easiest to take care of.
What is a rotary vane compressor?
Rotary Vane. Rotary vane compressors are like rotary screw compressors, but instead of screws, vanes are mounted on a rotor and rotated inside the cavity. The air compresses between the vane and its casing and is then pushed out at a different exhaust port.

How does a dynamic displacement compressor work?
Dynamic displacement compressors utilize a rotating blade powered by an engine to generate airflow. The air is then restricted to create pressure, and the kinetic energy is stored within the compressor.
How does an air compressor work?
How air compressors work. In principle, air compressors turn rotary motion (kinetic energy) into increased pressure (potential energy). A power source drives the rotary motion, enabling the compression of air which we then typically capture inside an air tank or sometimes referred to as a receiver. Compressed air is then typically passed from ...
How does compressed air work?
Compressed air is then typically passed from the air tank to a tool or some mechanism which releases the potential energy in the compressed air and the air pressure in the air compressor tank reduces. As the air in the compressor tank reduces , the air compressor pump works to replenish the air pressure in the air tank so as to keep an consistent ...
How does a rotary vane compressor work?
By rotating a rotary vane shaft, the vanes of the compressor draw in free air, and compress it as they rotate, generating compressed air power. Read more about rotary vane air compressors here.

What is a reciprocating air compressor?
Reciprocating air compressors are positive displacement piston air compressors. The word reciprocates, can be defined as something moving back and forth. Reciprocating compressors contain cylinders with one closed end and a piston that moves inside them.
What are gas compressors made of?
Gas poweered air compressors are made up of 2 ends: Engine End. Air End. The engine end, as you may have guessed is made up of a gasoline or diesel powered engine which provides the rotary power required to rotate the compressor pump via belts or pulleys.
What is an axial flow compressor?
Axial-flow compressors are high-speed and very large-volume compressors that work, as you may have already guessed, by the airflow entering the compressor in the axial direction. They are a form of dynamic compressor that contains rotary and stationary components through which the air flows and then becomes compressed.
How does a compressor compress air?
In order to compress air, the internal components of a compressor must move or change position to mechanically force the air through the chamber where it is compressed and stored until use. Positive Displacement is the method that most compressors use. Air is pulled into a chamber that opens and closes, where the internal parts reduce the volume ...
How does a piston type compressor work?
Piston-type air compressors operate similarly to the combustion engine in your car. When the crankshaft's rod raises the piston inside the cylinder, it forces air into the compression chamber, decreases air volume (thus increasing air pressure) as the crankshaft drives the piston closed and pushes the compressed air into a storage tank as the piston opens again to draw more air in.
What is a single stage compressor?
Single-stage: the compressor uses a piston to compress the air in one stroke (a full rotation of the crankshaft that drives the piston a full motion). In some single-stage models, multiple pistons are used to divide up the work and can operate at lower RPMs and decibels.
Why do air compressors need lubrication?
Lubrication. Just like your car uses oil, air compressors need lubrication to continue running smoothly over time. Lubricated air compressors use oil to reduce wear and friction on their moving parts. In the case of piston compressors, the oil is applied to the system in one of two ways:
What type of compressor uses a rotating blade to compress air?
Piston, rotary-screw, and scroll-type air com pressors all use positive displacement to compress and store air. Dynamic (nonpositive) Displacement uses rotating blades on an impeller to pull air into the chamber, where the energy from the motion of the blades builds air pressure.
What is a scroll compressor?
Scroll Compressors. The third type of positive displacement compressor, scroll compressors are known for their highly-efficient, oil-free, and quiet operation. Similar to rotary compressors, the scroll design uses two interwoven metal pieces that work together but don't touch to create a vacuum.
Why is direct drive used in compressors?
This is the more economical option and is widely used across all compressor types because the belts can be adjusted to change with air demands. In a direct-drive system, the motor attaches directly to the crankshaft of the compressor, allowing for smaller designs and fewer maintenance requirements.
How does a natural gas compressor work?
Natural Gas Compressors work by mechanically increasing gas pressure in stages (or steps) until it reaches the desired delivery point . The starting pressure and the desired ending pressure will determine how many stages a compressor will have.
How does a screw compressor work?
A screw compressor uses two meshing helical screws or rotors to compress the gas. Gas enters the suction side and moves through the threads. As it does it is compressed and then exits at the discharge side at a higher pressure. Screw compressors are typically used for lower pressure and lower volume like a VRU.
What type of compressor is used in oil and gas?
The oil and gas industry uses two main types of compressors: reciprocating and screw. A natural gas reciprocating compressor uses pistons and positive displacement to compress the gas. Gas enters the manifold, flows into the compression cylinder, then discharges at a higher pressure.
