BUILD 08 · OPERATE
It was fine yesterday. What changed?
A machine in service fails in a small number of ways, and each one has a spectrum. This step reads the failure mode from the residual gas rather than from the pressure alone.
What already answers this
Nothing below is a copy. Each line is the surface of this site that carries the answer, and what it carries.
- /tools/rga-abacus/ fingerprints observed peaks against the contaminant library
- /tools/spectrum-abacus/ gives the ratio and the decision for every documented signature
- /academy/troubleshooting/ walks air leak, virtual leak, water and hydrocarbon from their spectra
- /essays/no-dashboard-pumps-faster/ says what a dashboard can and cannot see about a pump
What the pump corpus can tell you about the machine you run
206 validated models across 9 families, 2797 parameters, each one carrying the source key and the page it was read on. Every family below is a family this site can name a model in.
| Family | Models | With a published pumping speed | With a published ultimate pressure |
|---|---|---|---|
| cryo gm | 34 | 6 | 1 |
| ion diode | 13 | 13 | 13 |
| ion noble diode | 8 | 8 | 8 |
| ion star | 7 | 7 | 7 |
| neg cartridge | 1 | 0 | 0 |
| neg ion combo | 6 | 0 | 0 |
| tmp classic | 33 | 27 | 19 |
| tmp hybrid | 73 | 66 | 59 |
| tmp maglev | 31 | 27 | 27 |
A machine that drifts is read from its residual gas first, and from what its pump is rated to do second. This step carries the second. It does not carry failure modes, and the block above says why rather than leaving the absence to be guessed.
Not in the base yet
What this step cannot answer, and why. Every count below is read from the corpus at build, so this block shrinks on its own the day the data grows.
- unsourced The pump corpus is here, 206 models across 9 families with 2797 sourced parameters, and this step reads it. What it does not read is failure modes: 0 are exported. Their prose is written in French in the producing repository and this site is served in English, so they are held back rather than machine-translated, because translating a source would be inventing it.
- unsourced No service interval, no mean time between failures and no wear model is carried for any component. A Bill of Vacuum built here says nothing about when to service it.
