Today marine air offers compact self contained systems and multi ton chilled water systems to cover all ranges of boat sizes.
Marine air compressor line diagram.
The refrigeration plants on merchant vessels play a vital part in carrying refrigerated cargo and provisions for the crew on board.
As the name itself suggests and these compressors have the rotary motion instead of reciprocating motion of the internal parts responsible for compressing the air.
The compressing medium or gas depends on the application such as if air is used it is termed as an air compressor.
It may be in line or even in v shape.
Choose a pipe system preview the layout in 3d and order your parts online with our easy to use compressed air line system design tool.
Now we will take a very brief look at one more type of compressors namely rotary compressors.
This will include joints gaskets major spare parts such as piston piston rings bearings etc.
Marine air soon added chilled water systems to its product line to meet the needs of the largest yachts.
Like pumps compressors can be classified as either kinetic machines which includes centrifugal and axial compressors or positive displacement machines which include reciprocating and rotary compressors.
Click the image to enlarge the simple reciprocating air compressor has a piston which reciprocates inside the cylinder wall and cylinder head.
Aluminium lightweight design well balanced excellent heat transfer working control instrument air.
To understand the operation of an air compressor let us assume the cycle and indicator diagram for a simple single stage reciprocating air compressor as shown below.
The emergency air compressor is not to be counted as a normally used machinery.
If it is in line usually the 1st stage and 2nd stage are in a same cylinder head block.
7 sizes of screw compressors to cover a range of approximately 50 to 2800 m h air receivers.
They are of higher capacity of all.
You ll get the expertise and guidance you need at every step you can build your perfect compressed air piping system quickly and effortlessly.
In reefer ships the temperature of the perishable or temperature sensitive cargo such as food chemical or liquefied gas is controlled by the refrigeration plant of the ship.
But in a v shaped compressor the 1st stage and 2nd stage may be entirely different connected by high pressure pipes.
Versatile design for a wide range of on board applications made to withstand corrosion.
Common marine air products.
An air compressor has a cylinder head which differs depending upon the type.
During maneuvering these compressors when put in use fills up the air bottle faster than other compressors thus.
Air compressor may be overhauled for planned maintenance or stripping down for survey purposes.
