Zomwe zachitika pamakina atsopano a WQ a mapampu a zimbudzi ogwira ntchito bwino kwambiri zikuwonetsa - chitoliro chachikulu chosatsekeka chagwiritsidwa ntchito bwino pa ntchito yokonzanso malo opopera zimbudzi

1. Zotsatira

Pulojekitiyi ikutsimikizira kuti tinthu tating'onoting'ono titha kufalikira bwino kwambiri, ndipo imayang'ana kwambiri kafukufuku woyambira wa makhalidwe akunja ndi makhalidwe amkati kuti akonze bwino magwiridwe antchito a unit mozungulira ukadaulo wa hydraulic simulation wa multi-scheme. Pambuyo poyesa magwiridwe antchito a hydraulic a makina enieni, mphamvu ya prototype ndi prototype pambuyo podula imakhala yayikulu kwambiri kuposa mphamvu yamagetsi ya unit yamagetsi yopopera madzi a zimbudzi ndi zimbudzi. Deta ikuwonetsedwa mu Table 1.

Gome 1 Kugwiritsa ntchito bwino kwa pampu ya zinyalala zomwe zimalowa m'madzi komanso kugwiritsa ntchito bwino mphamvu zomwe zili pamlingo woyamba

Mtundu wa pampu ya zinyalala zolowa pansi	Kwenikweni anayeza bwino mayunitsi	Kugwiritsa ntchito bwino kwa pampu yamagetsi yoyendera madzi a m'madzi ndi zimbudzi, mtengo wogwiritsira ntchito mphamvu moyenera pamlingo woyamba
300WQ700- 14-37 (Chitsanzo)	76.10%	64.80%
300WQ700- 11-30 (Chitsanzo pambuyo podula)	75%	64.50%

Kudzera mu deta yeniyeni yoyezedwa ndi kuyerekeza deta ya pampu ya zinyalala yolowa m'madzi, zidapezeka kuti:

(1) Zotsatira zenizeni za mayeso a hydraulic performance zinasonyeza kuti mphamvu ya unit inaposa mphamvu ya unit yamagetsi yogwiritsira ntchito zinyalala ndi zimbudzi.

(2) Zotsatira zenizeni za mayeso a hydraulic performance zikusonyeza kuti malo ogwiritsira ntchito bwino kwambiri a pampu yamagetsi adaphimba kwathunthu kuchuluka kwa ntchito ya pampu ya 0.7 ~ 1.3Qd yomwe yafotokozedwa mu standard ya dziko lonse ya GB/T 24674-2021 ya mapampu amagetsi ogwiritsidwa ntchito m'madzi a zimbudzi ndi zimbudzi, zomwe zimapangitsa kuti pakhale mphamvu zambiri komanso magwiridwe antchito ambiri.

(3) Zotsatira zenizeni za mayeso a hydraulic performance zinasonyeza kuti pamene kuchuluka kwa kudula kwa impeller external diameter kufika pa 8%, mphamvu ya unit inachepa ndi 1.1% yokha.

2. Zomwe Zachitika pa Pulojekiti

Chiwerengero cha masamba a impeller ndi m'lifupi mwa malo otulukira ndi zomwe zimayimira kapangidwe ka mpeller wa wide flow channel osatseka. Kafukufuku wa polojekitiyi adaganizira mokwanira za kukula kwa tinthu todutsa m'mimba mwake komanso momwe unit imagwirira ntchito.

Kawirikawiri, chiwerengero cha masamba chikachepa, mphamvu ya tsambalo yoletsa kuyenda kwa madzi imaipiraipira, ma vortice a axial amapangidwa mu njira yoyendera, momwe madzi amayendera mkati mwake zimakhala zovuta, ndipo kutayika kwa madzi m'njira kumawonjezeka. Choyimitsa cha polojekitiyi yowongolera chimagwiritsa ntchito njira yotulutsira madzi, yomwe imakulitsa njira yachiwiri yozungulira madzi yomwe imapangidwa m'mphepete mwa njira yotulutsira madzi. Zinthu zonsezi zimaletsa kusintha kwa magwiridwe antchito a unit. Deta yeniyeni yoyesera makina ikuwonetsa ndikuyerekeza kuti polojekitiyi yapambana pa liwiro la 220-260.

3. Njira yofufuzira ndi chitukuko

Zotsatira za polojekitiyi sizingasiyanitsidwe ndi ukadaulo wofunikira wa hydraulic Research&D womwe unasonkhanitsidwa ndi gulu laukadaulo la Liancheng komanso njira yolondola yopangira ukadaulo wa pampu ya zinyalala yolowa m'madzi.

(1) Kapangidwe kake kamachokera pa thupi lomwelo la pampu. Pansi pa mawonekedwe a masamba ochepa, m'lifupi mwa tsamba lotulukira, ngodya yoyika tsamba lotulukira, ndi m'mimba mwake wakunja wa impeller zimagwirizanitsidwa kuti zipeze yankho labwino kwambiri m'magawo osiyanasiyana.

(2) Kapangidwe kake kamaganizira zinthu zingapo monga ngodya yokulunga tsamba, m'mimba mwake wakunja wa impeller, m'lifupi mwa tsamba lotulukira, m'mimba mwake wa khomo lolowera impeller, ndi malo olowera tsamba kuti zitsimikizire kuti tinthu tating'onoting'ono titha kudutsa.

(3) Mphepete mwa cholowera cha tsamba chimakonzedwa mwapadera mu kapangidwe kake kuti chiteteze bwino kugwidwa kwa ulusi.

(4) Kapangidwe ka thupi la pampu yoyenda ndi njira yayikulu yozungulira maziko kamakhala kofanana ndi injini yoyenda ndi njira yayikulu yosatsekeka kuti zitsimikizire kuti tinthu tating'onoting'ono titha kutuluka bwino kudzera mu injiniyo motsatira thupi la pampu.

4. Kusintha kwa zomwe zakwaniritsidwa

Kampani ya gululi ili ndi luso lonse lopanga ukadaulo wa pampu ya zimbudzi komanso luso langwiro loyang'anira kupanga ndi kupanga. Injini yolowa m'madzi, pampu ya zimbudzi, ndi kabati yowongolera magetsi ili ndi zaka zoposa 30 zaukadaulo wopanga, kupanga ndi kupanga zinthu m'gululi, zomwe zimapereka yankho lathunthu pakukweza ndikusintha zida zapampu ya siteshoni ya pampu ya zimbudzi.
