Zipangizo zobowola zokhala ndi ma tapered zimaperekanso gawo la hexagonal chuck kuti lipereke mwayi kwa chuck bushing yozungulira, yomwe nthawi zambiri imakhala ndi kolala yokhazikika kuti isunge malo owoneka bwino a shank pakubowola mwala, ndikufananiza pang'ono poyambira kumapeto. Mabowo amabowoledwa mu ma increments a 0.6m kuti akwaniritse kutalika kwa mwendo wa mpweya. Ndi malowedwe okwera, mabowo owongoka, moyo wautali wautumiki komanso mtengo wotsika pa mita yobowoleredwa kuposa chitsulo chophatikizika, zida zobowola zokhala ndi tapered zikutenga gawo la msika kuchokera kuzitsulo zobowola, makamaka pantchito zamigodi ndi mafakitale amiyala.
Mitundu yosiyanasiyana ya miyala ndi kubowola miyala kumafuna ngodya zosiyanasiyana. Pobowola miyala yokhala ndi mphamvu yayikulu ya hydraulic pamiyala yapakati-yolimba mpaka yolimba komanso yonyezimira, nthawi zambiri imagwiritsidwa ntchito ngati taper angle. Makona a 11 ° ndi 12 ° nthawi zambiri amagwiritsidwa ntchito pamabowo amakono. Pobowola miyala yocheperako komanso mapangidwe ocheperako amiyala, ngodya yopapatiza ya 7° imagwiritsidwa ntchito. Mbali ya 7 ° ingagwiritsidwenso ntchito ngati kupota pang'ono kuli vuto mukamagwiritsa ntchito zida za 11 ° ndi 12 °. Kuonjezera apo, ngodya ya 4.8°(komanso 4°46’) ndi yabwino kwa thanthwe lofewa mukamagwiritsa ntchito makina obowola pneumatic kapena hydraulic - kuteteza ting'onoting'ono kuti zisazungulire kapena kutsekeka. Ndodo imodzi imagwiritsidwa ntchito kubowola mabowo aafupi (≤2.0m), pomwe ndodo zotsatizana zimagwiritsidwa ntchito kuboola mabowo akuya (mpaka 2.0m), kupewa kupindika kupsinjika mochulukira.
Ndodo zobowola za Plato zimabwera ndi magiredi atatu, ndipo utali umapezeka kuchokera ku 600mm (2') mpaka 11,200mm (36'8"), (kuyezedwa kuchokera pa kolala mpaka kumapeto kwa tapered).
Magiredi a Taper Rods Gome Lovomerezeka:
| Maphunziro | Mitundu | Mikhalidwe yoyenera |
| Wapamwamba | G III, T III, | 1) Kubowola miyala kumakhudza mphamvu: ≥76J, kawirikawiri chitsanzo: YT28 2) Kubowola kuya: ≥ 2.5 m (8’ 2 27/64”) 3) Mapangidwe a miyala: yolimba kwambiri, yolimba, yapakati yolimba komanso mwala wofewa Kuuma kwa Protodyakonov: f ≥ 15 Uniaxial Compressive Mphamvu: ≥150 Mpa 4) Zosintha: G ndodo, G I ndodo, ROK |
| Wamba | G ine, ROK | 1) Kubowola miyala kumakhudza mphamvu: ＜ 76 J, nthawi zambiri chitsanzo: YT24 2) Kubowola kuya: ≤2.5 m (8’ 2 27/64”) 3) Mapangidwe a miyala: Mwala wolimba komanso wofewa Protodyakonov Kuuma Scale: f ＜15 Uniaxial Compressive Mphamvu: ＜150 Mpa 4) Zosintha: G ndodo |
| Chuma | G | 1) Kubowola miyala kumakhudza mphamvu: ＜ 76 J, nthawi zambiri chitsanzo: YT24 2) Kubowola kuya: ≤2.5 m (8’ 2 27/64”) 3) Mapangidwe a miyala: Mwala wolimba komanso wofewa Protodyakonov Kuuma Scale: f ＜10 Uniaxial Compressive Mphamvu: ＜100 Mpa |
Zofotokozera mwachidule:
| Ndodo Utali | Digiri ya Taper | ||
| Shank Style | mm | phazi/inchi | |
| Hex 22 × 108 mm | 500 ~ 8,000 | 1’ 8” ~ 26’ 2” | 7°, 11° and 12° |
| 25 × 108 mm | 1500 ~ 4,000 | 4'11" ~ 13'1" | 7° |
| Hex25 ×159mm | 1830 ~ 6,100 | 6' ~ 20" | 7 ° ndi 12 ° |
Ndemanga:
1.The wamba kugwirizana taper digiri ndi 7 °, 11 ° ndi 12 °, madigiri ena monga 4.8 °, 6 ° ndi 9 ° ziliponso pa pempho;
2.Shank wamba ndi Hex22 × 108mm, Hex25 × 159mm ndi masitaelo ena amapezekanso ngati atapempha makasitomala;
3.Utali wa ndodo uyenera kufotokozedwa mwadongosolo;
4.Kuti mugwirizane ndi mikhalidwe yosiyanasiyana ya miyala, ndodo yobowola imasankhidwa ndi ogwiritsa ntchito.
Kodi kuyitanitsa?
