How big is a Detroit air piston compressor?
How big is a Detroit air piston compressor?
With a 90L 2hp, we even cater for the small home-based workshop. The range extends up to a 20hp work-horse capable of delivering a massive 2000LPM of air output at 8 bar max operating pressure. Starting the range 200L 5.5hp, we cater for the small workshops, tyre fitment centres etc.
What causes a compressor cylinder to misalign?
Compressor cylinder bore misalignment can cause failures that are often not attributed to misalignment. Crosshead shoes uneven wear, compressor piston rod failure at both the crosshead and at the piston, compressor piston rod coating failure, piston wear and compressor cylinder bore wear can all be attributed to cylinder misalignment.
How is cylinder alignment done on a reciprocating compressor?
The male and female fits between the crosshead housing, the distance piece and the cylinder were used as a starting point for alignment. The optical alignment tool was used to direct the alignment procedure. The optical alignment scope is set up on the opposite side of the crankcase from the cylinder.
What causes the crosshead of a compressor to tilt?
A heavy piston and rod can cause the crosshead or piston to tilt and results in acceptable rod runout with out-of-tolerance cylinder bore alignment.
Where is the ESS piston located in the compressor?
The ESS piston, located in the head of the compressor, controls the flow of air within the compressor itself. The piston allows the charging or pressurizing of the system’s air tanks. In the “loaded” mode, the ESS piston is down – or sealed – and air enters the system through the air inlet reed valve.
How does the piston move in a reciprocating compressor?
Inside the reciprocating compressor housing, one piston moves up and down in each cylinder. When the piston is at its lowest point, superheated gas enters the compressor through the inlet valves. When the piston moves up, the inlet valve closes and the gas pressure increases, due to the reduced volume.
Compressor cylinder bore misalignment can cause failures that are often not attributed to misalignment. Crosshead shoes uneven wear, compressor piston rod failure at both the crosshead and at the piston, compressor piston rod coating failure, piston wear and compressor cylinder bore wear can all be attributed to cylinder misalignment.
What are assumptions about reciprocating compressor cylinder alignment?
In the case of reciprocating compressors, I have found that there are two assumptions about the cylinder bore to crosshead bore alignment that have caused unexpected problems. The first assumption is “if the compressor rod runout is in tolerance then the cylinder bore alignment is in tolerance”.
