Sei midziyo yako inogara ichisunungura? Ndeipi mari yekusarudza giredhi rebhaudhi risiri iro?
Muminda yezvigadzirwa zvemaindasitiri, zvivakwa zvekuvaka, michina inorema, nezvimwe, kusunungura bhaudhi idambudziko rakajairika asi rine njodzi. Izvo hazvikonzere chete kuzunguzika kwemidziyo uye kuwedzera ruzha, asi zvinogona kukonzera kukanganisa kwekubatanidza, tsaona dzekuchengetedza, uye kunyange mamirioni ekurasikirwa kwekugadzirisa.
Mudzi wedambudziko kazhinji uri pakusarudza giredhi rebhaudhi risiri iro. Ichi chinyorwa chichaburitsa:
- Chikonzero chaicho chiri kusunungura bhaudhi
- Mibairo mitatu yakakomba yekusarudza giredhi risiri rebhaudhi
- Nzira yekusarudza zvakarurama mabhoti epamusoro-simba?
- Sei mabhaudhi ako achigara achisununguka?
- Kusakwana simba, kusakwana tensile / shear resistance
Kana mabhaudhi akajairwa (akadai segiredhi 4.8) achishandiswa mumidziyo yakakwira-mutoro, anoremara nyore nyore nekuda kwekunetseka kwakanyanya, zvichikonzera kurasikirwa kwepreload uye pakupedzisira kusunungura.
Nyaya: Bhandi rekutakura mugodhi rinoshandisa mabhaudhi egiredhi 4.8. Mushure memwedzi ye3, yakasunungurwa nekuda kwekudengenyeka, zvichiita kuti bhanhire ritsauke, uye kurasikirwa kwekugadzirwa kwekumiswa uye kugadzirisa kwakapfuura $ 50,000.
- Thread mismatch, kushomeka kweanti-kusunungura kuita
Coarse thread (UNC) iri nyore kusunungura munzvimbo yakakwirira-frequency vibration, nepo tambo yakanaka (UNF) kana anti-kusunungura tambo (seSpirax) inogona kupa zvirinani kukiya maitiro.
Nyaya: Fekitari yemotokari yakashandisa mabhaudhi akajairwa kugadzirisa injini, uye mabhaudhi akadonha nekuda kwekudengenyeka, zvichikonzera kuyeuka.
- Kurapwa kwepamusoro kusiri iko uye kusagadzikana friction coefficient
Mabhaudhi asina kugadzirwa anowanzoita ngura mukupisa kwepamusoro, hunyoro kana nharaunda dzinoparadza, zvichikonzera kudzikiswa kwe torque uye kuderedzwa kwekutanga.
Nyaya: Purojekiti yemagetsi yemhepo yekumahombekombe yakashandisa mabhaudhi akajairwa, uye kubatana kweshongwe kwakatadza nekuda kwekuora kwemunyu kwapera gore rimwe gare gare.
- Iwo matatu makuru mitengo yekusarudza isiriyo bhaudhi giredhi
- Njodzi dzekuchengetedza: kukundikana kwebhaudhi = njodzi yenjodzi
Muzvimiro zvakakosha zvakaita semabhiriji, simba remhepo, uye midziyo yekumanikidza, kutadza kwebhaudhi kunogona kukonzera kudonha, kuputika, kana kukuvara.
Chiitiko chaicho: Muna 2019, chirimwa chepetrochemical chakadonha nekuda kwekutyoka kwebhoti, nekurasikirwa kwakananga kunodarika madhora maviri emamiriyoni.
- Kukwira kwemitengo yekuchengetedza
Equipment downtime + bolt replacement + yevashandi mari inowanzo 5-10 nguva inodhura kupfuura yakananga kushandisa mabhaudhi ane simba.
Data: Mari yekugadzira yekambani yegore negore yakawedzera ne $120,000 nekuda kwekushandiswa kwemabhaudhi egiredhi yakaderera.
- Kukuvadza mukurumbira wemhando
Zvichemo zvemutengi nekuda kwematambudziko ebhaudhi zvinogona kukanganisa kubatana kwenguva refu uye kutokonzeresa kupokana kwemutemo.
- Ungasarudza sei giredhi rebhoti nenzira kwayo?
- Sarudza giredhi resimba maererano nemutoro
| Application Scenario | Inokurudzirwa nhanho | tensile simba |
| General mechanical equipment | 8.8 | ≥800 MPa |
| Simba remhepo, mabhiriji, michina inorema | 10.9 | ≥1000 MPa |
| Aerospace, midziyo chaiyo | 12.9 | ≥1200 MPa |
- Matanidza zvakatipoteredza zvinodiwa
Yakakwira vibration nharaunda → Sarudza yakanaka shinda + naironi yekuvhara nati
Nzvimbo inoparadza → Sarudza Dacromet kana simbi isina tsvina A4-80
Yakakwira tembiricha nharaunda → Sarudza alloy simbi (senge 42CrMo)
- Tsvaga vatengesi vane hunyanzvi kudzivirira fake
Inoda zvinyorwa zvinyorwa (MTC), munyu wekupfapfaidza bvunzo chirevo, ISO 9001 chitupa.
Mazano: Shandisa magineti bvunzo, chaiyo 10.9 giredhi mabhaudhi anowanzo asina simba remagineti (alloy simbi).
- 4. Pfupiso: Usarege mabhaudhi ave iwo asina kusimba chinongedzo!
✔ Low-simba mabhoti = mabhomba asingaoneki, izvo zvinogona kukonzera kuchengeteka uye njodzi dzemari.
✔ Sarudzo chaiyo inogona kuwedzera hupenyu hwemidziyo uye kuderedza mari yekugadzirisa.
✔ Sarudza mutengesi akavimbika kuti ave nechokwadi chekuti zvinhu uye maitiro anoenderana nezvinodiwa.
Mudziyo wako uri kushandisa mabhaudhi akakodzera here? Kugamuchirwa kubvunza timu yedu yeinjiniya yemahara kuti uwane yakagadziridzwa mhinduro!
