Compressor diagnostics
Compressor vibration diagnostics
Assess vibration on suitable compressor packages with the machine type, drive arrangement, speed and operating state built into the interpretation.
Asset-specific vibration analysis
Compressor type changes what “normal” looks like
Screw, reciprocating and centrifugal compressors do not produce the same vibration pattern. A useful diagnostic starts by identifying the compressor type, drive arrangement and operating condition before comparing the mechanical evidence.
EchoShift can focus on the motor, coupling or belt drive, accessible bearings, casing and support structure to determine where abnormal vibration is concentrated and what maintenance check should follow.
Maintenance triggers
When to book compressor vibration analysis
Compressor work starts by identifying the compressor type, drive arrangement and the symptom: changed vibration, bearing concern, drive behaviour or a load-sensitive mechanical issue.
A bearing, coupling or belt-drive concern needs evidence
The package behaves differently with load or operating state
A post-maintenance mechanical check is required
What we investigate
Vibration evidence tied to the machine
Vibration is interpreted against compressor type, speed, load and measurement location so expected forcing is separated from a meaningful mechanical change.
Motor and drive condition
Motor bearings, coupling or belt-drive behaviour can be assessed as part of the compressor train.
Bearing condition
Accessible bearing locations can be checked for changes in overall and higher-frequency vibration.
Running-speed and harmonics
Rotational and harmonic patterns help distinguish mechanical forcing from the machine’s expected operating signature.
Looseness and support
Skids, feet, guards and package structures can transmit or amplify compressor vibration.
Load-sensitive vibration
Features that change with compressor load or process state can be separated from persistent mechanical behaviour.
Type-specific excitation
Reciprocating, screw and centrifugal machines each have characteristic forcing patterns that must be interpreted in the correct machine context.
Measurement strategy
Scope the measurement plan to the compressor type
Measurements focus on rigid, accessible motor, drive, bearing, casing and support locations. Compressor type, speed, load and operating state are recorded so the vibration is interpreted against the actual machine behaviour and duty.
On-site vibration analysis: measurements are taken while the machine is operating in a representative condition where safe access allows, with the operating condition recorded alongside the readings.
What you receive
Engineering output for a maintenance decision
You receive a type-aware engineering finding covering the motor/drive, accessible bearings, casing or support structure and the most useful maintenance or specialist follow-up action.

A practical next step for inspection, specialist follow-up, recheck or monitoring
On-site process
A focused vibration investigation
The visit preserves compressor type, duty and drive context throughout the analysis because the same spectral pattern can mean different things on different compressor architectures.
Identify compressor configuration
Confirm type, drive arrangement, speed, load and recent maintenance.
Measure accessible mechanical points
Capture repeatable readings from the motor, drive, bearings, casing and supports as applicable.
Interpret in machine context
Compare rotational, harmonic, bearing and load-sensitive behaviour against the compressor configuration.
Recommend the next check
Direct maintenance toward the most useful mechanical or specialist follow-up action.
Choose the service
Snapshot first, monitoring when time adds value
A mechanical compressor concern can start with a snapshot. Continuous monitoring is more useful on critical packages or where load-dependent and intermittent behaviour needs repeat observation.

Questions
Compressor vibration FAQs
Practical answers to common questions before an on-site diagnostic.
Do you diagnose every type of compressor in the same way?
No. Screw, reciprocating and centrifugal compressors have different forcing patterns, so the measurement plan and interpretation are matched to the compressor type.
Can you assess the motor and compressor drive in one visit?
Yes. Comparing the motor, coupling or belt drive and compressor-side vibration is often useful for locating the source of a mechanical change.
Is continuous monitoring available for compressors?
It can be. Critical compressor packages are often strong candidates for trend monitoring when a one-off snapshot cannot capture intermittent or developing behaviour.
