Tech/Engineering - Energy / Power Generation
English term or phrase: Surge line
Ez a kérdés tulajdonképpen három, egymáshoz kapcsolódó kérdésből az első, külön-külön teszem fel őket.
A téma egy kompresszor (HP Compressor - még nem tudom, mit rövidít a HP).
Ennek a működését mutatja a grafikon, ahol a 3 lehetséges színes vonal neve:
Red - Surge line
Yellow - Control line
Green - Dead-band line
A vonalak nincsenek rajta a grafikonon, csak a nevük, így nem tudom az egymáshoz való viszonyukat leírni.
Az X-tengely az a Flow% (vagyis áramlás), az Y-tengely pedig Head %, ami az ügyfél által elfogadott régi fordítás szerint Nyomómagasság.

Szóval, mi a Surge line neve magyarul?
(A másik két vonalat külön kérdem meg.)

nyomáslengés vonal
Explanation:
“Surge” is caused when the flow through a compressor is decreased to the point that momentary flow reversals occur. Surge is evidenced by vibration and pulsation, and if unchecked can cause severe compressor damage.
If the compressor is operating safety (1), and flow suddenly decreases, the compressor can move into a surge condition (2), unless the blowoff valve is opened, and flow increased (3). While too little blowoff can result in surge, too much blowoff (4) wastes fuel, since the compressor energy is vented into the atmosphere.

Explanation:
Kompresszor esetében a surge befulladást jelent, a szótár szerint. :)

surge line
nyomásesés/nyomásingadozás kezdete


Explanation:
A surge hidrotechnikában jelent még víztükör-kilengést, vízszínlengést, nyomáslengést is, de ha kompresszorról van szó, akkor valószínűbb a fenti válasz, vagyis az a nyomás (határérték) amelynél a kompresszor teljesítménye már nem állandó.

"To assure compressor stability during engine operation, an engine is designed with a surge margin. This entails assuring that the operating point remains a specified distance from the surge line on the performance map. Large surge margins are employed due to transient conditions that move the compressor operating point closer to the surge line. However, a large surge margin that places the compressor operating line far from the surge line can preclude operation at the peak pressure rise or maximum efficiency region. Also, the increase in operational range results in additional flexibility for matching the compressor with the other gas turbine engine components.

The term surge line is actually a misnomer as two types of instability can develop: surge and rotating stall.

Surge is a global axisymmetric oscillation of the flow through the compressor that can include reverse flow during a portion of the surge cycle. These oscillations can result in severe damage to the mechanical components of the engine from the unsteady thrust load or the ingestion of combustion gases into the compressor and engine inlet. In a severe surge cycle, the reversed flow through the compressor can extinguish combustion, resulting in a "flame out" or total loss of engine power.

Ezt még kiegészíteném azzal, hogy a surge a műszaki szótár értelmében kompresszorok esetében nyomáslengést, tehát fluktuációt jelent. Ha a vezérlő vonaltól a nyomás/áramlás változása a nyomáslengés irányába tér el,a nyomáslengés hatására a kompresszor ütészajokat hallat és erősen rázkódik. Ezt a hatást visszakeringető vagy nyomáslengés-gátló szelep beiktatásával kerülik el. A dead band linera nincs ötletem, hacsak nem *holtsáv vonal*.

surge line
erős fordulatszám-ingadozás vonal


Explanation:
A http://66.249.93.104/search?q=cache:0WARRXW9ccMJ:www.cs.purd... webhelyen van egy kiváló, de nehezen olvasható cikk. Aki nem tudja elolvasni, annak elküldöm a grafikonokat e-mail mellékletként.
A grafikonon szerepel egy stabil működést jelző vonal, és egy instabilitást jelző vonal, amit surge-line névvel illetnek.

"The term surge line is actually a misnomer as two types of instability can develop: surge and rotating stall. Surge is a global axisymmetric oscillation of the flow through the compressor that can include reverse flow during a portion of the surge cycle."

A magyarázatban szereplő "rotating stall" kifejezés "lelassulás"-ként fordítható. Már a fordulatszám letassulását.
Az említett grafikon vízszintes tengelye a "mass flow", míg a függőleges "pressure ratio" ábrázolására szolgál.
