Valiva emenyeka singa omudumu gw’emikono gukyuka mu ddembe?

Mu mbeera z’okukozesa valve z’amakolero, omudumu gw’emikono kye kitundu ekisinga okukola obulungi, era okukyukakyuka kwakyo okukyukakyuka kutera okusalibwawo obubi ng’ekiraga kyokka embeera y’obulamu bwa vvaalu. Wabula okunoonyereza ku kabenje k’obukuumi akavudde ku vvaalu okukulukuta munda mu kkolero ly’eddagala mu Jiangsu mu 2024 kwalaga nti enkola y’omudumu gw’omu ngalo eya vvaalu y’akabenje teyalabika ng’ekwatiddwa mu nkola yonna, naye ekifo we basiba kyalina okwambala okutasobola kuddamu. Omusango guno guvuddeko okufumiitiriza kw'amakolero ku kutegeera okw'ennono nti "enzitowerera w'omukono= vvaalu eya bulijjo". Ekiwandiiko kino kigatta emisingi gy’okukola vvaalu, emitendera gy’okugezesa amakolero n’emisango egy’okulemererwa egya bulijjo okwekenneenya mu nkola entegeke enkolagana wakati w’embeera y’okukola omudumu gw’emikono n’embeera entuufu ey’okukola eya vvaalu.

Ebirimu .
1. Enkola y’ebyuma n’okuteeka mu nkola enkola y’omudumu gwa vvaalu .
2. Okukyusakyusa okw’eddembe ≠ Okulemererwa kwa ziro: Ensonga mukaaga ez’okwonooneka okukwekebwa .
3. Enkola y’okuzuula eby’ekikugu: Ebipimo by’okwekenneenya okusukka okutegeera kw’omudumu gw’emikono .
4. Ebikwata ku kuddaabiriza amakolero: Etteeka lya zaabu ery’okuddaabiriza okuziyiza .
5. Ensalo ya tekinologiya: Engeri Okuzuula Okutegeera Okuddamu Okuddamu Okuzimba Valve Health Management .

1. Enkola y’ebyuma n’okuteeka mu nkola enkola y’omudumu gwa vvaalu .
Nga ekitundu ky’okukola enkomerero eky’olujegere lw’okutambuza vvaalu (Ekifaananyi 1), embeera y’okuzimbulukuka kw’Omudumu gw'emikono .Kiraga embeera y’emirimu mu kitundu yokka ey’enkola y’okutambuza ekikolo kya vvaalu. Okusinziira ku GB/T 12224-2015 "Ekyetaagisa mu bulambalamba ku valve z'ekyuma", torque ekola ku mudumu gw'emikono erina okufugibwa mu yinginiya obukuumi 30-350N·M. Omutindo guno tegukoma ku kukakasa nti gukola bulungi, naye era gwewala okwonooneka kw’ebyuma olw’amaanyi agasukkiridde.

Okwekenenya enkolagana y’ebitundu ebikulu:

Olujegere lw’okutambuza amasannyalaze:Omupiira gw’omu ngalo → Ekikolo kya vvaalu Nut → Ekikolo kya vvaalu → Disiki ya vvaalu (Ekifaananyi 2)

Ekikulu Ekikulu:Okusikagana wakati w’ekikolo kya vvaalu n’okupakinga bwe kusinga 0.3MPa, omudumu gw’emikono gujja kuba n’okutegeera okw’amaanyi okw’okuzibikira .

Design ekifo ekizibe:Ekyuma ekiyitibwa worm gear box limit device bwe kiremereddwa, omudumu gw’emikono gusobola obutakola 360℃nga teguvuga valve disc .

2. Okukyusakyusa okw’eddembe ≠ Okulemererwa kwa ziro: Ensonga mukaaga ez’okwonooneka okukwekebwa .

Ensonga 1: Okusiba Pair Idle .

Mu vvaalu y’omulyango, ekituli wakati w’omutwe gwa square ekikolo kya vvaalu n’omulyango t{0}}slot kisukka 0.5mm (Figure 3), enzitowazo y’omudumu gw’emikono tesobola kuvuga kusengulwa kwa kikomera. Ebibalo okuva mu kyuma ekisunsula mu 2023 biraga nti ekika kino eky'okulemererwa "pseudo-Flexible" kikola ebitundu 17% ku bibaddewo mu kugwa kwa vvaalu omwaka gwonna.

Ensonga 2: Enkola y’okusitula .
Mu nsengekera y’okutambuza ggiya y’ensowera, singa bbeeri y’empiso eba ekutuse naye ng’ekiyumba tekisasika, omudumu gw’emikono gukyayinza okukuuma ebitundu ebisukka mu 60% eby’eddembe ly’okuzimbulukuka. Mu kiseera kino, obulungi bwennyini obw’okutambuza torque mu kikolo kya vvaalu bukendedde okutuuka ku bitundu 42% ku muwendo gwa dizayini.

Ensonga 3: Okukuŋŋaanyizibwa kw’okukyukakyuka kw’obugumu (elastic deformation) .
Valiva y’omupiira waggulu wa DN300 bw’efuna okunyigirizibwa kwa payipu okumala ebbanga eddene, omubiri gwa vvaalu gujja kuyita mu kukyukakyuka kw’obuveera bwa 0.02-0.15mm. Okukyukakyuka kuno okw’obutonde obutono tekujja kulemesa kukola kwa mudumu gwa ngalo, wabula kujja kuleeta 0.03mm obutakwatagana wakati w’omupiira n’entebe ya vvaalu, era omugerageranyo gwa puleesa y’okusiba gujja kugwa ebitundu 76%.

Ensonga 4: Okuyingirira kwa Crystallization okw’omu makkati .
Mu valve za kemiko, obutafaali nga boric acid ne ammonium sulfate bukuŋŋaanyizibwa mu kisenge kya vvaalu okukola layeri ey’okwekutula ennyo (Figure 4). Mu mbeera eno, obuziyiza bw’okuzimbulukuka kw’omudumu gw’omu ngalo bweyongera ebitundu 12% byokka, naye okufiirwa kwa vvaalu ya vvaalu entuufu kutuuka ku bitundu 83%.

Ensonga 5: Okulemererwa kw’ekitundu eky’emirundi ebiri-okuziyiza ekituli ekya wakati .
Mu dizayini y’okusiba ey’enjuyi ebbiri (bidirectional sealing design) ya vvaalu y’omupiira eya welded mu bujjuvu, nga ssupu ya vvaalu eya wansi ey’omugga preload efiirwa 30%, ebipimo by’okukola omudumu gw’emikono bikyali mu bbanga erya bulijjo, naye omulimu gw’okukendeeza puleesa y’ekisenge wakati gubadde gubula ddala.

Ensonga 6: Digital Twin Deviation .
Enkola ya digital feedback system ya intelligent valve actuator bw'eremererwa, okukyama wakati wa "electronic smoothness" ne "mechanical jamming" kuyinza okubaawo. Mu mwaka gwa 2024, ekifo ekimu eky’okufunira LNG mu ssaza ly’e Zhejiang kyaleetera enkola ya ESD okusalawo obubi olw’okulemererwa ng’okwo.

3. Enkola y’okuzuula eby’ekikugu: Ekipimo ky’okwekenneenya okusukka okutegeera kw’omudumu gw’emikono .

Okubumbako
Embeera y'okukyusakyusa omudumu gw'emikono kye kiraga ekikulu kyokka eky'okukebera obulamu bwa vvaalu, era "okukyukakyuka kwayo" kuyinza okubikka ebitundu ebisukka mu 70% eby'obulabe obuyinza okuva mu kulemererwa. Nga tufulumya enkyusa empya eya API 598-2024 enkola y’okukebera, amakolero gakyuka okuva ku kusalawo okukoleddwa okudda ku data-okuzuula okutuufu okugobererwa. Kirungi amakolero okuteekawo enkola ey’okwekenneenya ey’ebitundu bisatu omuli okwekenneenya torque, okuzuula omukka ogufuluma mu bbanga, n’okutegeera okw’amagezi, n’okutunuulira omutindo gwa ISO 15848-1 okulongoosa ekifo eky’okuterekamu emirimu. Nga tumenya "enzikiriza y'enzikiriza y'omukono" yokka y'esobola okutuuka ku bukuumi obuzaaliranwa obw'okuddukanya vvaalu mu bulamu bwayo bwonna.

1: Wheels za valve zisobola okukozesebwa mu mbeera enzibu?

A: Yee, emidumu gya vvaalu giyinza okukolebwa okugumira embeera enkambwe nga tukozesa ebintu ebigumira okukulukuta, UV n’ebbugumu eringi.

2: Nkola ntya ku valve handwheel entuufu ku nkola yange?

A: Ensonga z’olina okulowoozaako ng’olonda omudumu gwa vvaalu mulimu obunene bwa vvaalu, embeera y’okukola, torque eyetaagisa n’obwetaavu bw’ebintu byonna eby’okwongerako (nga enkola z’okusiba oba ebiraga ekifo).

3: Enkola y’okusiba omudumu gwa vvaalu mu vvaalu?

A: Enkola y’okusiba omudumu gwa vvaalu ekozesebwa okuziyiza okukola kwa vvaalu okutakkirizibwa oba mu butanwa.

4: Nkola ntya okukuuma omudumu gwange ogwa valve?

A: Okwoza n’okusiiga buli kiseera omudumu gwa vvaalu bisobola okuyamba okulaba ng’okola bulungi. Okugatta ku ekyo, obubonero bwonna obw’okwambala oba okwonooneka bulina okukolebwako mu bwangu okutangira ensonga endala.
