Air compressors are mechanical equipment that uses electricity. They should be installed and handled with care because of safety and repair costs. While working with air compressors in the production plant, managers expect technicians to apply professionalism. Let’s see some technical requirement that ensures the smooth running of this equipment.
General Technical Overview of Air Compressors
Air compressors produce air pressure with rotating impellers and supply other tools. Apart from industrial use, air compressors are used at home, mechanic workshops and constriction yards. Many air compressor fittings use an internal combustion engine that runs on either gas or electric motor. They convert these forms of energy into kinetic energy.
If you use air compressors with dryers, it’s possible to sieve water moisture that comes with atmospheric air. When the efficiency of the air compressor is low, it might be hard to enjoy optimum benefits.
Applying compressed air with vapour to tools that run on moisture-free air can be a disaster. It’s important to use refrigeration dryers and other types of air compressors with high performance. When heat dryers can’t separate these vapour, pressure from compression will lead to condensation. This condition can spoil your compressor’s cylinders, air motors, and pneumatic tools. Usually, the manufacturer loses when these industrial air compressors damage the quality of their products.
How Piston and Portable Air Compressors Work
By compression air, there will be a pressure build-up and drop in the volume. This system of using air compression also works with many pneumatic and power tools. In regular compression systems with the reciprocating piston technology, different components work to provide efficiency.
Apart from the piston, some important components of this technology include the valve head and cylinder. Other components of this internal combustion system are crankshaft and connecting rods.
Usually, piston air compressors have tanks for storing large volumes of air at respective pressure. The air pressure inside this tank varies with usage. While you operate the unit, the electric motor maintains the pressure according to the operator’s needs.
It’s a different system for portable air compressors. These types don’t come with air tanks but operate like piston air compressors. However, operators enjoy these compressors because they are portable. Since they are not location-bound, it’s easy for operators to use them in different work sites.
Generally, portable air compressors with gas and electric motors work with cylinders. This cylinder is the big chamber where internal combustion occurs. At the end of the cylinder are discharging valves that supply compressed air. Depending on the function, a discharge valve could be an inlet or outlet passage.
Without a valve head, there will be no structural support for both inlet and discharge valves. It’s inlet valves that draws air for pistons to compress. Then, discharge valves send compressed air to units or tools that need it.
During operations, the piston is in constant (back and forth movements) motion. When the piston moves back, vacuum builds up for the inlet valves to suck. Each stroke of the piston brings more air into the tank and increases the pressure. Then the compressed air moves with sped through discharge valves. However, there’s often an automatic switch-off when the pressure gets to 125 PSI. This process occurs simultaneously in most efficient air compression systems.
What Are the Common Differences?
Choose an air compressor model that aligns with your work requirements. However, these are common differences between the piston and portable air compressors.
There are two types of a piston air compressor – the single-stage, and (dual) two-stage. Unlike the single-stage type, single-stage compressors have one piston. In the dual-stage system, each revolution needs two strokes of piston movement.
Generally, portable compressors are handy and efficient for providing continuous air pressure. This type of air compressor is ideal for doing light household tasks, and it works with a minimal footprint.
