Namuhla, ngizokhuluma iqiniso ukuthi angilokothi ngikhulume obala embonini, futhi ngemva kokuyifunda, ngizokonga okungenani u-30% wesabelomali.
1. Umbala webhrakhethi ≠ izinga lekhwalithi
Isiliva liyi-zinc efakwe ngogesi, elimnyama lifuthwa ngopende omnyama, futhi izindleko zezindlela ezimbili zokucubungula zicishe zifane. Mane nje ufake i-oda ngokusekelwe ekubukekeni. Ungakhohliswa yisisho esithi 'lapho ingubo ijiyile, ivikela kakhulu ukugqwala'. Isici sangempela sekhono lokuvimbela ukugqwala ubude bokuhlolwa kokufuthwa kukasawoti, hhayi umbala.
2. Ibhuleki eliseceleni noma ibhuleki eliphindwe kabili? Okokuqala hlola indawo yokuthumela impahla ngaphandle ngaphambi kokufaka i-oda
Ama-oda angu-90% avela eYurophu naseMelika asebenzisa amabhuleki aseceleni – anesakhiwo esilula nesingabizi kakhulu, futhi uma ephuka, lonke isondo lizolahlwa;
Ama-90% amapulatifomu e-e-commerce asekhaya asebenzisa amabhuleki amabili - anokubukeka okuku-inthanethi kanye nokuphakama okwengeziwe kokufakwa okungu-3mm, okubiza kakhulu ngo-8% -12%.
Isiphetho: Khetha amabhuleki aseceleni okuthumela imishini kwamanye amazwe kanye namabhuleki amabili emikhiqizweni yasekhaya ethandwayo, ngaphandle komehluko ekusebenzeni. Ungaphambanisi “intela yobuhle” nethi “intela yokusebenza”.
3. Ingabe amasondo ensimbi aqinile? Kumane kuyindaba yekhulu leminyaka elidlule
Amasondo afanayo angama-intshi angu-4, inguqulo ebunjiwe ye-nylon enamandla amakhulu enomthamo oguquguqukayo wokuthwala umthwalo ongu-280 kg, inguqulo yensimbi ebunjiwe eno-260 kg, anzima, anomsindo omkhulu, futhi athambekele kakhulu ekugqwaleni. Isizathu esenza amasondo ensimbi ebunjiwe asakwazi ukusinda nanamuhla yinye kuphela - lapho intengo ye-aluminium ebunjiwe ikhuphuka, yayishibhile ngo-0.8 yuan/ingxenye.
4. Isiqubulo sokuthengisa esithi “Okuqukethwe kwensimbi=ukumelana nokugqwala”
Amasondo e-PU, e-nylon, kanye nerabha avela kubakhiqizi abasemthethweni aphumelele ukuhlolwa kokufuthwa kukasawoti ongathathi hlangothi kwamahora angu-48, kuyilapho amasondo e-iron core eqala ukugqwala ngemva kwamahora angu-24 okuhlolwa ngenxa yokugqwala kwe-electrochemical. Ukusebenzisa imali eyengeziwe engu-15% ukuthenga "into egqokile ethwala umthwalo" akulungile?
5. Ingabe amasondo enjoloba athambile ngempela kune-PU? Angalungiseka! Angalungiseka! Angalungiseka!
Ukwengeza i-plasticizer eyengeziwe engu-5% kufomula kungandisa ubulukhuni bamasondo enjoloba bube ngu-95 A, obunzima kune-nylon; I-PU engu-65A ingasetshenziswa njenge-'jacket yekotini ethule'. Ngaphambi kokufaka i-oda, cela umthengisi ukuthi akubonise isivivinyo sobulukhuni be-Shore, ungabe usekhohliswa amagama athi 'irabha ethambile'.
6. Ama-double bearing=high-end, ama-single bearing=low-end? Bheka lesi sigameko!
Ama-bearings amabili: umthwalo ophezulu ongaguquki, umsindo ophansi, ubiza ngo-30%, afanele imishini yezokwelapha kanye nezimoto zokudlela ezisezingeni eliphezulu;
Ukuthwala okukodwa: umthwalo oguquguqukayo ophezulu, ukumelana kokuqala okuphansi, intengo eshibhile engu-30%, efanelekile ezinqoleni zezokuthutha kanye namabhasikidi okushintshana.
Ukufaka i-double axis bearing onyaweni lomugqa wokuhlanganisa kuzonciphisa ijubane kuphela; Umhlengikazi wakhononda ngomsindo ngosuku olulandelayo ngemuva kokufaka i-single bearing embhedeni we-ICU. Thatha umuthi ofanele, ungawuphindi kabili ngokungazi.
7. Iyunithi yokulinganisa ngamasentimitha, hhayi “amasentimitha emakethe”!
Osayizi abavame ukubizwa ngama-intshi angu-3, ama-intshi angu-4, kanye nama-intshi angu-5 emakethe bonke babhekisela kuma-intshi angu-1 “=25.4 mm.
Amasentimitha angu-3 ≈ 75 mm, amasentimitha angu-4 ≈ 100 mm, amasentimitha angu-5 ≈ 125 mm.
Ukubhala amasentimitha angu-4 njengo-“100 mm” kulungile, kodwa ukubhala ngokuthi “amasentimitha angu-4 emakethe” (≈ 133 mm) kumane nje kulinde ukubuyiselwa.
