Bese kuba nezindlu ezithwalayo ku-mixer uqobo. Akumele yakhelwe nje ukuthi ibambe i-bearing, kodwa ivumele ukuchithwa kokushisa, ukugcotshwa okufanele, kanye nokungafaki izinto ezingcolisa inqubo. Izindlu ezingakaphonswa kahle ezinezimbobo zangaphakathi ezibamba amafutha nokushisa zizopheka ama-bearings ayo. Ikhwalithi yokulingisa—ukuminyana kwayo, ukungaguquguquki, nokuqedwa kwayo—ibaluleke kakhulu. Leli inani elifihliwe lomnikezeli onolwazi kulo ukubunjwa kwegobolondo futhi ukutshala imali. Umsindo, ukusakaza okuhlanzekile kwe-bearing block noma indlu ye-gearbox iqhawe elithembekile lokuthembeka.
Umhlangano We-Agitator: Ngaphezu Kwesamba Sezingxenye Zawo
Wonke umuntu ugxile ekwakhiweni kwe-impeller—i-hydrofoil, i-turbine, ihange. Lokho kubalulekile emiphumeleni yenqubo. Kodwa umhlangano owuphethe ubalulekile ukuze usinde. I-shaft, ihabhu, ama-blades, ama-fasteners. Ingabe ama-blades ashiselwe, noma abhawudi? Ukushisela kungadala ingcindezi futhi kuhlanekezele iphimbo elinembile le-hydrofoil. I-Bolting ivumela ukushintshwa kodwa yethula amaphuzu okugqwala kwemifantu uma ingaklanyelwe futhi yenziwe ngezinto ezifanele.
Sibe necala ngesiqhumiseli esikhulu, esishiselwe-injini yomoya lapho amabhawodi ayelokhu exega khona, naphezu kokusebenzisa ilokha yentambo. Imbangela yalandelwa emuva kokuncane, kodwa okunqwabelanayo, ukubekezelelana komshini ezikhaleni zempande ye-blade kanye nehabhu. Ngaphansi komthwalo, kwakukhona ukudlala okwanele ukudala ukunyakaza okuncane, okusebenzise ama-bolts axege. Ukulungiswa kwakungewona amawasha wokukhiya; ibilungisa kabusha ihabhu nama-blades njengesethi efaniswe ekubekezeleni okuqinile. Kwagqamisa lokho ku-complex isidlali emibuthanweni, izingxenye zidinga ukwenziwa ngomshini kucatshangelwa umhlangano wazo wokugcina, ngokuvamile ngezandla ezifanayo noma ngaphansi kokuxhumana okuqinile.
Lolu uhlobo lokubuka okuphelele olulethwa umhlinzeki wesevisi ephelele. Uma inkampani iphatha i- ukutshala imali ye-impeller kanye nelandelayo CNC imishini ezindaweni ezikhuphukayo, zilawula izindawo ezibucayi. Ukungaguquguquki endaweni yezinto ezibonakalayo, ukuqonda ukuthi imishini yesakhiwo esisansimbi, konke kuhlanganisa ingxenye yokugcina enokwethenjelwa kakhudlwana.
