Torque Tightening
Kuti uwane inovuza-isina flange yekubatanidza, kuisirwa gasket kwakaringana kunodiwa, mabhaudhi anofanirwa kupihwa pane chaiyo bhaudhi tension, uye iyo yakazara bhaudhi simba rinofanira kukamurwa zvakaenzana pamusoro pese flange kumeso.
NeTorque Tightening (kushandiswa kwekutanga kurodha kune chekumisikidza nekutenderedzwa kweiyo fastener nati) iyo chaiyo bolt tension inogona kuitika.
Kusimbisa kwakaringana kwebhoti kunoreva kushandisa zvakanyanya bhoti elastic properties. Kuti ishande zvakanaka, bhaudhi rinofanira kuita sechitubu. Mukushanda, iyo yekusimbisa maitiro inoshandisa axial pre-load tension pabhoti. Iyi tension load ndeyechokwadi yakaenzana uye yakatarisana nechisimba chekumanikidza chinoiswa pazvikamu zvakaunganidzwa. Inogona kunzi "kusimbisa mutoro" kana "tension load"

Torque wrench
Torque Wrench izita rezita rekushandisa rinotungamirwa neruoko, uye rinoshandiswa kunyatso kuseta simba rekusunga senge nati kana bhaudhi. Inobvumira mushandisi kuyera simba rekutenderera (torque) rinoshandiswa kune bhoti kuitira kuti ienderane kune zvakatemwa.

Torque kurasikirwa
Torque kurasikirwa kunowanikwa mune chero mabhaudhi akabatanidzwa. Izvo zvakasanganiswa mhedzisiro yekuzorora kwebhaudhi, (inenge 10% mumaawa makumi maviri nemana ekutanga mushure mekuiswa), gasket creep, vibration muhurongwa, kuwedzera kwemafuta uye kupindirana kwe elastic panguva yekusimbisa bhaudhi kunobatsira kurasikirwa kwe torque. Kana kurasikirwa kwe torque kunosvika pakunyanyisa, kumanikidza kwemukati kunodarika simba rekumanikidza rakabata gasket panzvimbo uye kubuda kana kuputika kunoitika.
Kiyi yekudzikisa izvi mhedzisiro ndeye yakakodzera gasket kuisirwa. Nekuunza maflange pamwe chete zvishoma nezvishoma uye parallel paunenge uchiisa gasket uye kutora mashoma mana mabhaudhi ekusimbisa anopfuura, achitevera akakodzera bhaudhi kusimbisa kutevedzana, kune mubhadharo mukuderedzwa kwemitengo yekuchengetedza uye kuwedzera kuchengetedzwa.
Yakakodzera gasket ukobvu kunokosha zvakare. Iyo gasket yakakora, iyo inokwira iyo gasket inokambaira izvo zvinogona kukonzera kurasikirwa kwetorque. Pane yakajairwa ASME yakasimudzwa kumeso flanges 1.6 mm gobvu gasket inowanzokurudzirwa. Thinner gasket zvinhu zvinogona kutora yakakwira gasket mutoro uye nekudaro yakakwirira yemukati kumanikidzwa.
Lubrication inoderedza friction
Lubrication inoderedza kupokana panguva yekuomesa, inoderedza kutadza kwebhaudhi panguva yekuisa uye inowedzera hupenyu hwebhaudhi. Kusiyana kwemafiction coefficients kunokanganisa huwandu hwe preload inowanikwa pane imwe torque. Kukwesha kwepamusoro kunokonzeresa shanduko shoma ye torque kuti itange kurodha. Iko kukosha kweiyo friction coefficient yakapihwa nemugadziri welubricant inofanirwa kuzivikanwa kunyatso simbisa kukosha kwetorque inodiwa.
Mafuta ekuzora kana anti-seizure makomisheni anofanirwa kuiswa kune ese ari maviri anotakura nzungu uye neshinda dzechirume.
Kuomesa kutevedzana
Kupfuura kwekutanga, simbisa bhaudhi rekutanga zvinyoro wobva wafamba wakananga mhiri kana 180 madhigirii kune yechipiri bhaudhi, wozofambisa 1/4 kutenderedza denderedzwa kana 90 madhigirii echitatu bhaudhi uye zvakananga kuyambuka kune yechina. Ramba uchitevedzana kusvika mabhaudhi ese asimbiswa.
Paunenge uchisimbisa mana-bolt flange, shandisa criss-cross pattern.
Kugadzirira flange bolt-up
Mukubatanidza flanged, zvese zvikamu zvinofanirwa kuve zvakarurama kuti uwane chisimbiso. Chinonyanya kukonzera leaky gasketed majoini ndiyo isina kufanira yekuisa maitiro.
Usati watanga maitiro ekubhaudha, anotevera matanho ekutanga anodzivirira matambudziko emangwana:
- Geza zviso zveflange uye tarisa mavanga; zviso zvinofanira kunge zvakachena uye zvisina kukanganisa (burrs, makomba, dents, nezvimwewo).
- Ongorora mabhaudhi ese nenzungu nemaziso kuona tambo dzakakuvara kana dzakaora. Tsiva kana gadzirisa mabhaudhi kana nzungu sezvinodiwa.
- Bvisa mabhura kubva kune ese shinda.
- Zora tambo dzebhaudhi kana stud, uye pamusoro pe nzungu yakatarisana neflange kana washer. Mawashi akaomeswa anokurudzirwa mune akawanda maapplication.
- Isa iyo gasket nyowani uye ive shuwa kuti gasket yakanyatso pakati. USASHANDISE zvekare gasket yekare, kana kushandisa MUTIPLE gaskets.
- Tarisa flange kurongeka ASME B31.3 Maitiro Piping:
... zviso zveflange zvinofanirwa kuenderana mukati me1/16 ″ paguti yedhayamita, uye maburi ebhaudhi eflange anofanirwa kurongeka mukati me1/8″ yakanyanya kubviswa. - Gadzirisa nzvimbo yenzungu kuti uve nechokwadi chekuti 2-3 tambo dzinoonekwa pamusoro pepamusoro pe nut.
Zvisineyi kuti ndeipi nzira yekusimbisa inoshandiswa, macheki akatemerwa pamusoro uye gadziriro nguva dzose dzinofanira kuitwa.
Chirevo (s) cheMunyori…
Zvangu pachangu nezve…Torque Wrenches
- Munguva yakapfuura ndakaunganidza mazana emahara-asina kunyuza-asina flange makubatanidza, kubva kuNPS 1/2 kusvika kuNPS 24 uye yakakura. Kashoma ini ndakashandisa saka Torque Wrench.
Mukuita, "zvakajairika" pombi flange yekubatanidza haisati yambounganidzwa neTorque Wrench. Kubatana kwakaomesesa kwandiri kwaigara kuri "vadiki" uyezve kunyanya iyo Yakasimudzwa Face mhando pamusoro peKirasi 300 (RF Height = ingangoita 6.4 mm).
Relationable zviso zveflange kubva kuNPS 1/2 flange idiki saka semuenzaniso NPS 6 flange, uye mukana wekukanganisa, mukuona kwangu wakakura.
Mukuita ini ndinosangana nguva dzose flange yekubatanidza, uko kurongeka kusingaite muganho wekushivirira. Kana zviri nyore kurongeka kweKusimbisa Procedure kuchiteverwa Mechanic haina kubatikana zvakanyanya. Pamwe inofanira kutangirwa pabhaudhi nhanhatu pane pabhaudhi rimwe. Shandisa maziso ako panguva yekusangana kweflange, yakakosha uye inobatsira zvakanyanya pamwe kune inovuza-isina kubatana
Zvisizvo zvinongedzo zveflange - mabhaudhi akanyanya kupfupika!
Chii chaungaita?
- Mufananidzo wacho unoratidza flange isina kuvharwa, nokuti mabhoti maviri akapfupika, uye nuts haisi zvachose pamabhoti. Izvi zvinoreva kuti chibatanidza chinogona kunge chisina kusimba sezvachinofanira kuva. Flanges dzakagadzirwa kuitira kuti iyo yose nut-bolt musanganiswa inobata masimba paflange. Kana nati ichingoiswa zvishoma pabhaudhi, chinongedzo chinogona kunge chisina kusimba zvakakwana.
- Kana basa rako richisanganisira kuisa midziyo pamwe chete, kubatanidza pombi ine flanged, mabhoti anovhara manhole kana mamwe mabhaudhi ekubatanidza pamidziyo, kana kumwe kuungana kwemidziyo, yeuka kuti basa racho harina kupera kusvikira mabhaudhi ese aiswa zvakanaka uye akasungwa.
- Mimwe michina inoda maitiro ekusimbisa mabhaudhi. Semuenzaniso, unogona kushandisa torque wrench kuti unyatso simbisa mabhaudhi kune yakatarwa, kana kuomesa mabhaudhi mune yakakosha kurongeka. Ita shuwa kuti unotevera nzira kwayo, shandisa maturusi akakodzera, uye kuti wakadzidziswa nemazvo mumagadzirirwo emidziyo.
- Tarisa mapaipi uye zvishandiso zvemabhaudhi maflange zvakanaka sechikamu chekuongorora kwako kwekuchengetedza chirimwa. Sekutungamira kuri nyore, mabhaudhi asingapfuuri nzungu anofanirwa kuongororwa nenyanzvi yekugadzira pombi kana mainjiniya.
- Kana ukaona mabhaudhi asina kuvharwa muchirimwa chako, zviudze kuti zvigadziriswe, uye ita shuwa kuti kugadzirisa kunodiwa kwapera.
- Ongorora midziyo mitsva, kana midziyo yakaunganidzwa patsva mushure mekugadzirisa, kuti uone kuti yakanyatso kuunganidzwa uye yakavharidzirwa zvakanaka isati yatanga.
Ndeupi hurefu hwakakodzera hweStud Bolt?
