Valve inspection
Clear and automatic judgement of the operating condition of steam traps and internal leakage of valves. It is also effective for inspection of valves on closed piping sections.
| Steam trap diagnosis | |
|---|---|
| Good | The surface temperature is as expected, and there is no detected ultrasonic sound. The steam trap is likely to be in proper operation condition. |
| Caution | The surface temperature is as expected, but there is some ultrasonic sound detected. The sound level is very low, so it is difficult to determine if the trap is operating properly or if there is a very small leak. Continue to observe the steam trap closely. |
| Leaking | A large amount of high-intensity ultrasonic sound is detected. There is a high possibility that the trap is leaking steam, and immediate repair or replacement is recommended. |
| Blocked | The surface temperature is less than 40 °C (104 °F). The trap is most likely blocked making condensate discharge impossible. Immediate cleaning, repair or replacement is recommended. |
| Valve diagnosis | |
|---|---|
| Good | No ultrasonic sound originating from the valve was detected. The valve seems to seal properly without leakage. |
| Caution | There is some ultrasonic sound detected. The sound level is very low, so it is difficult to determine if the valve seals properly or if there is a very small leak. Continue to observe the valve closely. |
| Leaking | A large amount of high-intensity ultrasonic sound is detected. The valve is likely leaking fluid, and immediate repair or replacement is recommended. |
| * Blocked is determined only when steam trap operation is detected. | |
Bearing inspection
By measuring shock waves (shock pulses) that occur when a bearing is scratched or lubricated poorly, the deterioration status can be determined. This can be used to collect data for daily trend management.
