S / S nkhani yogawa pampu imaganiziridwa makamaka kuchokera kumayendedwe, mutu, katundu wamadzimadzi, masanjidwe a mapaipi ndi momwe amagwirira ntchito. Nawa mayankho.

Zinthu zamadzimadzi, kuphatikiza dzina lamadzimadzi, zinthu zakuthupi, katundu wamankhwala ndi zinthu zina, zinthu zakuthupi zimaphatikizira kutentha c kachulukidwe d, mamasukidwe amadzi u, tinthu tating'onoting'ono tating'onoting'ono ndi mpweya wamkati, ndi zina zambiri, zomwe zimaphatikizapo mutu wa dongosolo, ogwira cavitation zotsalira Kuchuluka kuwerengetsera ndi abwino mpope mtundu: katundu katundu, makamaka amanena za corrosiveness mankhwala ndi kawopsedwe wa sing'anga madzi, amene ndi maziko ofunika kusankha kugawanika. pompa kake zakuthupi ndi mtundu wanji wa shaft chisindikizo kuti musankhe.

Kuyenda ndi chimodzi mwazinthu zofunika kwambiri pakusankha pampu, zomwe zimagwirizana mwachindunji ndi mphamvu yopangira komanso kutulutsa mphamvu ya chipangizo chonsecho. Mwachitsanzo, popanga mapangidwe a Design Institute, zowerengeka, zochepera komanso zothamanga kwambiri za mpope zitha kuwerengedwa. Posankha chitsulo chosapanga dzimbiri chotseguka mpope, tengani kuthamanga kwakukulu ngati maziko ndikuganizira kuyenda bwino. Ngati palibe kutuluka kwakukulu, nthawi zambiri 1.1 nthawi yomwe ikuyenda bwino imatha kutengedwa ngati kuthamanga kwakukulu.

Mutu wofunidwa ndi dongosolo ndi deta ina yofunikira yogwiritsira ntchito posankha pampu. Nthawi zambiri, mutu uyenera kukulitsidwa ndi 5% -10% malire kuti asankhe.

Malinga ndi makonzedwe a chipangizocho, mtunda wamtunda, milingo yamadzi, ndi momwe amagwirira ntchito, dziwani kusankha kwapampu yopingasa, ofukula ndi mitundu ina ya mapampu (paipi, submersible, pansi pamadzi, osatsekereza, kudzipangira okha, zida, ndi zina zambiri. ).

Mapangidwe a mapaipi a chipangizocho amatanthawuza kutalika kwa mayendedwe amadzimadzi, mtunda woperekera madzi, ndi njira yobweretsera madzi, monga gawo lotsika kwambiri lamadzimadzi kumbali yoyamwa komanso mulingo wapamwamba kwambiri wamadziwo kumbali yotulutsa, komanso zina. deta monga specifications payipi ndi utali wake, zipangizo, specifications chitoliro, kuchuluka, etc., Kuti achite mawerengedwe a mutu wa tayi-chisa ndi cheke wa NPSH.

Pali zinthu zambiri ntchito, monga madzi ntchito T, zimalimbikitsa nthunzi mphamvu P, kuyamwa mbali kuthamanga PS (mtheradi), kutulutsa mbali chidebe kuthamanga PZ, okwera, yozungulira kutentha, kaya ntchito ndi yapakatikati kapena mosalekeza, ndi udindo wa mpope yakhazikika kapena ayi. zochotseka.

Pakuti mapampu amadzimadzi ndi mamasukidwe akayendedwe wamkulu kuposa 20mm2/s (kapena kachulukidwe wamkulu kuposa 1000kg/m3), m'pofunika kuti atembenuke khalidwe pamapindikira pa mpope experimental madzi mu pamapindikira ntchito ya mamasukidwe akayendedwe (kapena pansi kachulukidwe), makamaka ntchito yoyamwa ndi mphamvu yolowetsa. Chitani zowerengera zazikulu kapena kufananiza.

Dziwani kuchuluka ndi kuchuluka kwapampu zapampu za S/S zoyamwa kawiri. Kawirikawiri, mpope umodzi wokha umagwiritsidwa ntchito pogwira ntchito bwino, chifukwa pampu imodzi yaikulu ndi yofanana ndi mapampu ang'onoang'ono awiri omwe amagwira ntchito mofanana (kutanthauza kukweza ndi kutuluka komweko), ndipo mpope waukulu uli ndi mphamvu zambiri. Kwa mapampu ang'onoang'ono, pakuwona kupulumutsa mphamvu, ndi bwino kusankha pampu imodzi yayikulu m'malo mwa mapampu awiri ang'onoang'ono, koma m'mikhalidwe yotsatirayi, mapampu awiri amatha kuganiziridwa mofanana: kuthamanga kwapakati ndi kwakukulu, ndipo mpope umodzi sungathe kufika. mlingo wotuluka izi. Kwa mapampu akuluakulu omwe amafunikira mlingo woyimilira wa 50%, mapampu ang'onoang'ono awiri amatha kusinthidwa kuti agwire ntchito, awiri oima (atatu onse).
