Tsarin shigarwa na famfon ruwa na centrifugal mai rage fitar da ruwa

Bayanan Fasaha da Nazarin Ayyukan Injiniya don Shigar da Masu Rage Eccentric a Inlet na Famfon Centrifugal:

1. Ka'idoji Don Zaɓar Hanyar Shigarwa Alkiblar shigarwa na masu rage yawan ruwa a mashigar famfunan centrifugal ya kamata su yi la'akari da halaye na buƙatun kariya daga kayan aiki da kuma yanayin ruwa, musamman bin tsarin yanke shawara mai matakai biyu:

Fifiko ga Kariyar Cavitation:
Idan gefen tsarin Net Positive Suction Head (NPSH) bai isa ba, ya kamata a ɗauki Tsarin Sama-Flat don tabbatar da cewa ƙasan bututun yana ci gaba da saukowa don guje wa tarin ruwa wanda zai iya haifar da cavitation.
Bukatun Fitar da Ruwa:Idan akwai buƙatar danshi ko kuma fitar da bututun, za a iya zaɓar Tsarin Kasa-Flat don sauƙaƙe fitar da ruwa daga matakin ruwa.

2. nazarin fasahar shigarwa ta sama
Fa'idodin Injinan Ruwa:
● Yana kawar da tasirin flexitank: Yana ci gaba da riƙe saman bututun don guje wa rarrabuwar ruwa da rage haɗarin taruwar jakar iska
● Ingantaccen rarrabawar saurin kwarara: Yana jagorantar sauye-sauyen ruwa mai santsi kuma yana rage ƙarfin tururin ruwa da kusan kashi 20-30%
Tsarin hana cavitation:
● Kiyaye yanayin matsin lamba mai kyau: hana matsin lamba na gida faɗuwa ƙasa da matsin lamba mai cike da tururi na matsakaici
● Rage bugun matsin lamba: Yana kawar da yankunan samar da vortex kuma yana rage yuwuwar cavitation
Tallafin ƙa'idodin ƙasa da ƙasa:
● Ma'aunin API 610 yana buƙatar: Ya kamata a shigar da sassan da ba su da alaƙa da shiga cikin ruwa a saman matakin
● Ma'aunin Cibiyar Hydraulic: An ba da shawarar don hawa lebur a matsayin misali don juriya ga cavitation

3. Yanayi masu dacewa don shigarwa na ƙasa-lebur
Yanayi na musamman na aiki:
● Tsarin Fitar da Danshi: Yana tabbatar da fitar da danshi yadda ya kamata
● Da'irar wanke bututu: yana sauƙaƙa cire laka
Diyya ta Zane:
● Ana buƙatar bawuloli na shaye-shaye
● Ya kamata a ƙara diamita na bututun shiga da maki 1-2
● Ana ba da shawarar a saita wuraren sa ido kan matsi

4. ma'aunin ma'anar shigarwa
An bayyana ta amfani da Ma'aunin Girman Geometric da Juriyar ASME Y14.5M:
Shigarwa mai lebur:jirgin ɓangaren da ba a saba gani ba yana da alaƙa da bangon ciki na saman bututun
Shigarwa mai faɗi a ƙasa:jirgin ɓangaren da ba a saba gani ba yana da alaƙa da bangon ciki na ƙasan bututun
Lura:A cikin ainihin aikin, ana ba da shawarar amfani da na'urar daukar hoto ta laser ta 3D don tabbatar da daidaiton shigarwa.

5. Shawarwari don aiwatar da aikin
Kwaikwayon lambobi:Binciken izinin cavitation (NPSH) ta amfani da software na CFD
Tabbatar da wurin aiki:Ana gano daidaiton rarrabawar saurin kwarara ta hanyar amfani da na'urar auna kwararar ultrasonic
Shirin sa ido:Shigar da na'urori masu auna matsin lamba da na'urorin auna girgiza don bin diddigin na dogon lokaci
Dabarun kulawa:Kafa tsarin dubawa na yau da kullun don mai da hankali kan lalacewar sashin bututun shiga

An haɗa ƙayyadaddun shigarwa a cikin ISO 5199 "Bayanin Fasaha don Famfunan Centrifugal" da GB/T 3215 "Sharuɗɗan Fasaha na Gabaɗaya don Famfunan Centrifugal don Masana'antar Matatar Mai, Sinadarai da Masana'antar Man Fetur".
