Nga ekitundu ekikulu eky’enkola y’amasannyalaze n’amazzi agatambuza amazzi, obwesigwa bwa autopipes bukosa butereevu obukuumi bw’emmotoka n’obulamu. Nga amakolero g’emmotoka ag’omulembe bwe geeyongera okukulaakulana okutuuka ku butuufu obw’amaanyi n’obuzibu obusingawo, okuddaabiriza payipu kuvudde ku kukyusa okwangu okudda ku pulojekiti entegeke okugatta ssaayansi w’ebintu, makanika w’amazzi, ne tekinologiya ow’okukola ebyuma ebituufu. Ekiwandiiko kino mu nkola kinnyonnyola enkola z’ekikugu n’obumanyirivu obw’omugaso mu kuddaabiriza autopipe okuva mu ndowooza z’okuzuula ensobi, obukodyo bw’okuddaabiriza, okulonda ebintu, n’okulondoola omutindo.
I. Ebika by’ensobi ebya bulijjo n’obukodyo bw’okukebera .
Okulemererwa kwa autopipe okwa bulijjo kweyoleka nga okukulukuta, okuzibikira, enjatika, n’okulemererwa kw’ebiyungo. Layini z’amafuta zitera okukulukuta kw’okuzimba kwa kapiira olw’okumala ebbanga eddene-okumalawo omukka gwa petulooli, ate layini z’amafuta eza puleesa nnyingi ziyinza okutawaanyizibwa enjatika z’obukoowu ez’ekyuma olw’okunyigirizibwa okukubiddwa. Payipu z’enkola y’okunyogoza zitera okulaba ekikolwa eky’okuziyiza (throttling effect) ekiva ku bitereke bya minzaani, ate layini za buleeki, olw’okukendeeza ku buwanvu bw’omunda obuva ku kukulukuta, zitera okuvaako amaanyi ga buleeki okufiirwa. Tekinologiya ow’omulembe ow’okukebera obulwadde asukkulumye ku buzibu bw’okukebera okulaba okw’ennono. Sensulo za puleesa ya digito zisobola okuzuula obulungi enkyukakyuka za puleesa ez’enjawulo nga za wansi nga 0.1 MPa. Infrared thermal imaging cameras zisobola okuzuula obuzibu bw’ebbugumu mu bifo ebikwekebwa. Endoscopes nga zigatta wamu ne fluorescent tracers zongedde ku kigero ky’okuzuula microcracks okutuuka ku 92%. Mu mbeera y’okuddaabiriza erimu ekika kya Girimaani, okwekenneenya okukankana kwa spectrum kwazuula bulungi ensibuko y’okumenya obukoowu mu payipu y’amafuta ga aluminiyamu aloy evudde ku bracket resonance.
II. Okussa mu nkola tekinologiya ow’enjawulo ow’okuddaabiriza .
Ebizigo eby’enjawulo eby’okuddaabiriza byetaagibwa ku bika by’ensobi eby’enjawulo. Ku payipu z’ekyuma ezifuuse ekivundu mu kitundu, oluvannyuma lw’okuggyawo ekitundu ekyonooneddwa nga tukozesa okusala kwa plasma, ebikozesebwa eby’enjawulo ebikutte omuliro bye bikozesebwa okuteekateeka ebiyungo ebisembayo, okukakasa nti obuwanvu bw’ekisenge obufaanagana bw’ebiyungo ebipya eby’ebiyungo biri mu mm 0.15. Nga tukyusa enkuŋŋaana za hoosi, ttooki eyali etikddwako ekiragiddwa omukozi (ebiseera ebisinga 25-35 N·m) erina okunywerera ddala, era ekisumuluzo kya torque kiteekwa okukozesebwa ku mirundi ebiri-okukakasa enkoona. Okuddaabiriza payipu ya woyiro eya puleesa ey’amaanyi kyetaagisa okufaayo ennyo ku kufuga obuyonjo. Embeera y’okuddaabiriza erina okutuukana n’omutindo gwa ISO 14644-1 Class 7 cleanroom, n’okuyonja ultrasonic ne isopropyl alcohol solution kulina okukolebwa nga tonnaba kuzigatta. Ekitabo ky’okuddaabiriza kkampuni empya ekola ku by’amasannyalaze kiggumiza mu ngeri ey’enjawulo nti oluvannyuma lw’okuddaabiriza, layini z’amazzi agabuguma zirina okugezesebwa puleesa ku puleesa y’okukola emirundi 1.5 (okumala waakiri eddakiika 15), era okukka kwa puleesa tekulina kusukka bitundu 3% ku muwendo ogusooka.
iii. Sayansi w'ebintu n'okukwatagana Okulonda .
Okulonda ebikozesebwa mu kuddaabiriza kikwata butereevu ku bulungibwansi bw’okuddaabiriza n’obulamu bw’okuweereza. Fluororubber (FKM) seals zisemba ku nkola z’amafuta, kubanga ziwa range y’okuziyiza ebbugumu -20℃okutuuka ku 200℃n’okuziyiza okulungi ennyo okuzimba mu ethanol-amafuta agatabuddwa. Inconel 625 Alloy yesinga okwettanirwa mu bitundu ebya waggulu-eby’ebbugumu (nga layini za turbocharger), nga bwe zikuuma amaanyi g’okuserengeta obulungi ennyo ne ku 850℃. Mu tekinologiya ow’omulembe ow’okuddaabiriza ebirungo ebikola omubiri (composite repair technology), carbon fiber-epoxy resin enywezeddwa ekozesebwa bulungi okuddaabiriza insulation ya payipu y’omukka eyonoonese. Obutambuzi bwayo obw’ebbugumu buba bwa kimu kya munaana bwokka obw’ebintu eby’ennono ebya asibesito, ate amaanyi gaayo ag’okusika gasinga emirundi esatu. Era kikulu okumanya nti ebikozesebwa mu kuweta payipu z’ebyuma eby’enjawulo birina okukwatagana ennyo. Okugeza, payipu za aluminiyamu alloy zirina okukozesa ER4043 welding wire ne argon shielded welding, nga welding current efugibwa mu 120-150A range.
iv. Okukakasa omutindo n’okuddaabiriza okuziyiza .
Enkola y’okukebera multi-eyeetaagibwa okukakasa omutindo gw’okuddaabiriza. Okugezesa puleesa kulina okukolebwa mu ngeri ey’emitendera, okutandika n’okukebera okukulukuta okusooka ku mirundi 1.2 ku puleesa y’okukola, olwo mpolampola okweyongera okutuuka ku bitundu 90% ku puleesa ya dizayini. Ekintu ekizuula amazzi agakulukuta mu masa ga haidrojeni kirungi okuzuula ekivundu, nga ekipimo ekitono ekizuulibwa ekya 5 × 10⁻1222 PA·M3/s. Ku kuddaabiriza okuziyiza, kirungi okugezesa pH y’okunyogoza pH buli kiromita 20,000 (ekisinga obulungi mu bbanga lya 7.5-8.5). Okukyusa ekinyogoza mu bujjuvu kyetaagisa nga konsikiti esukka 3000 μs/cm. Oluvannyuma lw'okussa mu nkola enkola y'okuddaabiriza "esatu-ey'omutindo," ekibinja ky'emmotoka ekimu eky'obusuubuzi kyalaba okukendeera kwa 67% mu miwendo gy'okulemererwa egyekuusa ku payipu. Ebipimo ebikulu mulimu okwekebejja okulaba buli mwezi ku kunyiga kwa clamp, okukebera ebifo ebikulu buli luvannyuma lwa myezi esatu nga bakozesa borescope, n’okukyusa buli mwaka kwa kapiira ka ssiringi zonna.
Nga amasannyalaze ganguyira mu kussa amasannyalaze mu mmotoka, okuddaabiriza okuziyiza okw’amaanyi (insulation maintenance of high-Voltage electric drive system cooling pipes) kufuuse ennimiro egenda okuvaayo. Abakola ku kuddaabiriza tekyetaagisa kukuguka mu bukugu bwa ndabirira ya kinnansi mu by’okukanika wabula era bamanyidde ddala enkola z’obukuumi eza waggulu-Voltage (nga okwambala ebyuma ebikuuma obutonde bwa CAT III). Mu biseera eby’omu maaso, enkola z’okuteebereza embeera ya payipu eyesigamiziddwa ku tekinologiya wa digito ow’amawanga abiri (digital twin technology) zijja kwongera okutumbula obutuufu bw’okuddaabiriza. Nga bakozesa enkola z’okuyiga ebyuma ezilondoola puleesa y’amazzi, ebbugumu, n’ebikwata ku kukankana mu kiseera ekituufu, zisobola okuwa okulabula nga bukyali ku kulemererwa okuyinza okubaawo nga bukyali ennaku 14-21. Kkampuni z’okuddaabiriza ez’ekikugu zirina okuteekawo enkola z’okuddaabiriza eza digito ezizingiramu databases ez’ebintu, enkola ya parameter libraries, ne case knowledge bases. Eno y’ekkubo ly’enkulaakulana eriteewalika okutumbula omutindo gw’okuddaabiriza n’okukola obulungi.
