Mfundo zosankhira ma valavu ndi njira zosankhira ma valavu

Mfundo yosankha mavavu
(1) Chitetezo ndi kudalirika. Zofunikira pakupanga mafuta, malo opangira magetsi, zitsulo ndi mafakitale ena kuti ntchito yopitilira, yokhazikika, komanso yayitali igwire ntchito. Chifukwa chake, valavu yofunikira iyenera kukhala yodalirika kwambiri, chitetezo chachikulu, sichingayambitse chitetezo chachikulu pakupanga komanso kuwonongeka kwa anthu chifukwa cha kulephera kwa valavu, kuti ikwaniritse zofunikira pakugwira ntchito kwa nthawi yayitali kwa chipangizocho. Kuphatikiza apo, chepetsani kapena pewani kutayikira komwe kumachitika ndi mavalavu, pangani fakitale yoyera, yachikhalidwe, kukhazikitsa thanzi, chitetezo, ndi kasamalidwe ka chilengedwe.

(2) Kukwaniritsa zofunikira pakupanga njira. Valavu iyenera kukwaniritsa zosowa za kugwiritsa ntchito mphamvu yapakati, yogwira ntchito, kutentha kwa ntchito ndi kugwiritsa ntchito, zomwe ndizofunikira kwambiri pakusankha valavu. Ngati valavu ikufunika kuteteza kupanikizika kwambiri ndikutulutsa mphamvu yochulukirapo, valavu yotetezeka ndi valavu yodzaza idzasankhidwa; kuti mupewe kubwereranso kwa valavu yapakati panthawi yogwira ntchito, gwiritsani ntchitovalavu yoyezera; kuchotsa madzi oundana, mpweya ndi mpweya wina wosaundana womwe umapangidwa mu chitoliro cha nthunzi ndi zida zina, pamene kuletsa kutuluka kwa nthunzi, valavu yotulutsira madzi iyenera kugwiritsidwa ntchito. Kuphatikiza apo, ngati chosungiracho chikuwononga, zipangizo zabwino zopewera dzimbiri ziyenera kusankhidwa.

(3) Kugwiritsa ntchito, kukhazikitsa ndi kukonza kosavuta. Valvu ikayikidwa, wogwiritsa ntchitoyo ayenera kudziwa bwino komwe valavu ikupita, chizindikiro chotsegulira ndi chizindikiro chosonyeza, kuti athe kuthana ndi mavuto osiyanasiyana adzidzidzi. Nthawi yomweyo, kapangidwe ka mtundu wa valavu yosankhidwa kayenera kukhala koyenera momwe zingathere, kosavuta kukhazikitsa ndi kukonza.

(4) Zachuma. Poganizira za kukwaniritsa kugwiritsa ntchito mapaipi amagetsi mwachizolowezi, mavavu okhala ndi mtengo wotsika wopanga komanso kapangidwe kosavuta ayenera kusankhidwa momwe angathere kuti achepetse mtengo wa chipangizocho, kupewa kuwononga zinthu zopangira mavavu ndikuchepetsa mtengo wokhazikitsa ndi kukonza mavavu mtsogolo.

Masitepe osankha mavavu
1. Dziwani momwe valavu imagwirira ntchito malinga ndi momwe valavu imagwirira ntchito mu chipangizo kapena njira yopangira. Mwachitsanzo, malo ogwirira ntchito, kuthamanga kwa ntchito ndi kutentha kwa ntchito, ndi zina zotero.

2. Dziwani kuchuluka kwa magwiridwe antchito a valavu malinga ndi malo ogwirira ntchito, malo ogwirira ntchito komanso zofunikira kwa ogwiritsa ntchito.

3. Dziwani mtundu wa valavu ndi momwe galimoto imayendera malinga ndi cholinga cha valavu. Mitundu mongavalavu ya gulugufe yolimba, valavu yowunikira, valavu ya chipata,valavu yolinganiza, ndi zina zotero. Njira yoyendetsera galimoto monga nyongolotsi ya wheel worm, yamagetsi, ya pneumatic, ndi zina zotero.

4. Malinga ndi chizindikiro cha valavu. Kupanikizika kwapadera ndi kukula kwapadera kwa valavu ziyenera kufananizidwa ndi chitoliro choyendetsera chomwe chayikidwa. Ma valavu ena amatsimikiza kukula kwapadera kwa valavu malinga ndi kuchuluka kwa madzi kapena kutuluka kwa valavu panthawi yoyesedwa ya sing'anga.

5. Dziwani mawonekedwe olumikizira pamwamba pa valavu ndi chitolirocho malinga ndi momwe zimagwirira ntchito komanso kukula kwa valavuyo. Monga flange, welding, clip kapena ulusi, ndi zina zotero.

6. Dziwani kapangidwe ndi mawonekedwe a valavu malinga ndi malo oikira, malo oikira, ndi kukula kwake kwa valavu. Monga valavu ya chipata cha dark rod, valavu ya angle globe, valavu ya mpira wokhazikika, ndi zina zotero.

Malinga ndi makhalidwe a sing'anga, kuthamanga kwa ntchito ndi kutentha kwa ntchito, kusankha kolondola komanso koyenera kwa chipolopolo cha valavu ndi zipangizo zamkati.
