Cavitation boyayye barazana ce ga  famfo injin turbin tsaye  aiki, haifar da rawar jiki, hayaniya, da zaizayar ƙasa wanda zai iya haifar da gazawar bala'i. Duk da haka, saboda tsarin su na musamman (tsawon tsayi har zuwa dubun mita) da kuma hadaddun shigarwa, gwajin aikin cavitation (ƙaddamar da NPSHr) don famfunan injin turbin tsaye yana haifar da ƙalubale masu mahimmanci.

I. Rufe-Madauki Na'urar Gwajin Gwaji: Daidaitawa vs. Ƙuntataccen sarari

1.Ka'idoji da Tsarin Gwaji

• Babban Kayan Aiki: Tsarin madauki na rufe (famfo famfo, tanki mai stabilizer, na'urar motsi, na'urori masu auna matsa lamba) don madaidaicin sarrafa matsa lamba.

• Tsari:

· Gyara saurin famfo da yawan kwarara.

· A hankali rage matsa lamba har sai kai ya ragu da kashi 3% (ma’anar ma’anar NPSHr).

· Yi rikodin matsa lamba mai mahimmanci kuma ƙididdige NPSHr.

• Daidaiton Bayanai: ± 2%, mai dacewa da ka'idodin ISO 5199.

2. Kalubale ga Famfon Turbine a tsaye

• Ƙimar sararin samaniya: Ƙirar madaidaicin rufaffiyar madauki suna da tsayin tsayin mita ≤5 m, wanda bai dace ba tare da famfo mai tsayi (tsawon shaft na al'ada: 10-30 m).

• Karɓar Halayyar Mai Sauƙi: Gajerun igiyoyi suna canza saurin gudu da yanayin girgizawa, skewing sakamakon gwajin.

3. Aikace-aikacen masana'antu

• Amfani da Cases: Short-shaft zurfin rijiyoyin famfo (shaft ≤5 m), samfurin R&D.

• Nazarin Harka: Mai yin famfo ya rage NPSHr da 22% bayan inganta ƙirar impeller ta hanyar gwaje-gwajen madauki na 200.

II. Na'urar Gwajin Buɗe-Madauki: Daidaita Sassauci da Daidaitawa

1. Ka'idodin Gwaji

• Buɗe Tsari:Yana amfani da bambance-bambancen matakin ruwa na tanki ko injin famfo don sarrafa matsa lamba (mafi sauƙi amma ƙasa da daidai).

• Maɓalli na haɓakawa:

· Matsakaicin madaidaicin bambance-bambancen matsa lamba (kuskure ≤0.1% FS).

· Laser flowmeters (± 0.5% daidaito) maye gurbin gargajiya turbine mita.

2. Daidaitawar Jumhuriyar Turbine

• Kwaikwayo mai zurfi mai zurfi: Gina ramukan ƙarƙashin ƙasa (zurfin ≥ tsayin ramin famfo) don maimaita yanayin nutsewa.

• Gyaran Bayanai:Samfuran CFD yana ramawa ga asarar matsin lamba da ya haifar da juriyar bututun mai.

III. Gwajin Filin: Tabbatar da Duniya ta Gaskiya

1. Ka'idodin Gwaji

• Gyaran Aiki: Daidaita matsa lamba ta mashigai ta hanyar bawul throttling ko saurin VFD don gano wuraren sauke kai.

• Tsarin Maɓalli:

NPSHr=NPSHr=ρgPin+2gvin2-ρgPv

(Yana buƙatar auna matsi na mashigai, Fin ɗin gudu, da zafin ruwa.)

hanya

Shigar da madaidaicin na'urori masu auna firikwensin matsa lamba a flange mai shiga.

A hankali rufe bawuloli masu shiga yayin rikodin kwarara, kai, da matsa lamba.

Plot head vs. matsi na matsa lamba don gano ma'anar juyewar NPSHr.

2. Kalubale da Mafita

Abubuwan Tsangwama:

· Jijjiga bututu → Shigar da matakan hana jijjiga.

· Haɗin iskar gas → Yi amfani da na'urori masu lura da abun ciki na cikin layi.

• Daidaiton Haɓakawa:

· Matsakaicin ma'auni masu yawa.

Yi nazarin bakan jijjiga (farawar cavitation yana haifar da karuwar makamashi 1-4 kHz).

1. Tushen Ka'idar kamanceceniya

• Dokokin Tsara: Kula da takamaiman gudun ns; Sikelin impeller girma kamar:

· QmQ=(DmD)3,HmH=(DmD)2

• Zane-zane:  1: 2 zuwa 1: 5 ma'auni ma'auni; kwafi kayan da roughness surface.

2. Amfanin famfo Turbine a tsaye

• Daidaituwar sarari: Samfuran gajerun igiya sun dace da daidaitattun na'urorin gwaji.

•Tattalin Kuɗi: An rage farashin gwaji zuwa kashi 10-20% na cikakken sikelin samfuri.

Madogaran Kuskure da Gyara

• Tasirin Sikeli:  Matsalolin lambar Reynolds → Aiwatar da ƙirar gyaran hargitsi.

• Tashin Sama:  Samfuran Yaren mutanen Poland zuwa Ra≤0.8μm don daidaita asarar gogayya.

V. Kwaikwayon Dijital: Juyin Gwaji Mai Kyau

1. CFD Modeling

• Tsari:

Gina samfuran 3D masu cikakken kwarara.

Tsara kwararar lokaci mai yawa (ruwa + tururi) da ƙirar cavitation (misali, Schnerr-Sauer).

Maimaita har zuwa 3% faɗuwar kai; cire NPSHr.

• Tabbatarwa: Sakamakon CFD yana nuna ≤8% karkacewa daga gwaje-gwajen jiki a cikin nazarin yanayin.

2. Hasashen Koyon Injin

Hanyar Da Aka Koka Da Bayanai:  Horar da samfuran koma baya akan bayanan tarihi; shigar da sigogin impeller (D2, β2, da sauransu) don tsinkayar NPSHr.

• Amfani: Yana kawar da gwajin jiki, yankan zagayowar ƙira da 70%.

Kammalawa: Daga "Aikin Ƙaƙwalwar Ƙira" zuwa "Ƙididdigar Ƙididdiga"

Gwajin famfo famfo a tsaye dole ne ya shawo kan kuskuren cewa "tsari na musamman yana hana ingantacciyar gwaji." Ta hanyar haɗa rufaffiyar rufaffiyar/buɗaɗɗen madauki, gwajin filin, ƙirar ƙira, da simintin dijital, injiniyoyi na iya ƙididdige NPSHr don haɓaka ƙira da dabarun kulawa. Kamar yadda gwajin matasan da kayan aikin AI suka ci gaba, samun cikakkiyar ganuwa da iko akan aikin cavitation zai zama daidaitaccen aiki.
