I. Ongororo Yakajairika: Dombo rekona remachubhu asina musono anodhonzwa nechando ekuRussia

GOST 8734-75(zita rakazara: Machubhu esimbi asina musono akaremara anotonhora. Range) ndiyo yeRussia (yaimbova USSR)chiyero chehukuru/kupatsanurwayemapaipi esimbi asina musono anodhonzwa kana kuti anotonhorera. Yakatanga kushanda musi wa1 Ndira 1977. Mutemo uyu unosanganisira mapaipi asina musono anogadzirwa nechando (anogadzirwa nekudhonzwa kana kudhonzwa nechando) anedhayamita yekunze kubva pa1 mm kusvika 200 mmuyeukobvu hwemadziro kubva pa 0.2 mm kusvika 22 mm.

Maitiro ekudhonza/kudzumburudza nechando anoita kuti machubhu acho ave akarurama zvikuru uye ane hunhu hwakanaka hwepamusoro. Kuburikidza nekushanduka kwechando, simbi dzinonatswa, uye huwandu hwesimbi uye hunhu hwemakanika hunovandudzwa zvakanyanya. Iyi tekinoroji yekugadzira kutonhora yakanyatsogadzirwa inoita kuti machubhu acho ave akakwirira kupfuura machubhu ekare anovhumburudzwa nekupisa maererano nekushivirira, kusimba uye kupedzisa kwenzvimbo - zvichiita kuti ave akakodzera zvishandiso zvakarurama, masisitimu ehydraulic, maumbirwo emakanika akanyatsogadzirwa uye mamwe mashandisirwo akawanda anonetsa.

Mwero uyu wakavakirwa pamwero wepasi roseСТ СЭВ 1483-78uye yakatenderwa neUSSR State Committee for Standards musi wa13 Gumiguru 1975 (Chirevo Nhamba 2604). Chinyorwa chazvino chakashanda ndicho chakadhindwazve muna 2007.

II. Sisitimu Yakajairika: Hukama Hwakabatana pakati peGOST 8734 neGOST 8733

Muhurongwa hwemitemo yeRussia,GOST 8734-75inofanira kushandiswa pamwe chete nehunyanzvi hwayo hwehunyanzviGOST 8733-87(Machubhu esimbi asina musono akakanganisika - Mamiriro ehunyanzvi). Pamwe chete anoumba chiyero chakakwana chechigadzirwa chemachubhu esimbi:

Zvakajairika	Chiyero	Basa
GOST 8734-75	Kureba kwedhayamita yekunze, ukobvu hwemadziro, kushivirira kwakaenzana, mhando dzehurefu uye kutsauka kunobvumirwa, huremu hwedzidziso	"Chitarisiko chayo" - saizi
GOST 8733-87	Magiredhi esimbi, kuumbwa kwemakemikari, hunhu hwemakanika, bvunzo dzemaitiro, bvunzo dzemahydraulic, mitemo yekuongorora, kumaka, kurongedza	"Chinhu chipi uye chakasimba sei" - zvinodiwa zvehunyanzvi

Tsamba yekutenga: Mumagwaro einjiniya kana maodha ekutenga,GOST 8733 neGOST 8734 zvinowanzotaurwa pamwe chete- vanoumba vaviri vasingaparadzanise.

III. Kureba kweDzinza uye Kupatsanura

3.1 Rudzi rwechikero

Muyero weGOST 8734-75 unosanganisira zviyero zvinotevera:

Paramita	Range
Dhayamita yekunze	1 – 200 mm
Ukobvu hwemadziro	0.2 – 22 mm
Kureba (zvisingatarisirwi)	1.5 - 11.5 m
Kureba (kwakagadzika)	4.5 - 9 m(kutsauka kwemuganhu +10 mm)

3.2 Kupatsanurwa nehukuru hwemadziro

Zvichibva pachiyero chedhayamita yekunze (D) nehukobvu hwemadziro (s), machubhu akakamurwa kuita mapoka mana:

Chikamu	Chiyero cheD/s	Tsananguro
Rusvingo rwakatetepa zvakanyanya	D/s > 40	Ultra-lightweight, yekushandisa kuchengetedza huremu
Rusvingo rwakatetepa	D/s = 12.5 – 40	Machubhu emadziro matete akajairika
Madziro akakora	D/s = 6 – 12.5	Kukwanisa kwepamusoro-soro kunotakura kumanikidzwa
Rusvingo rwakakora zvakanyanya	D/s < 6	Kushandiswa kwekumanikidzwa kwakanyanya

3.3 Kushivirira kwedhayamita yekunze

Dhayamita yekunze (mm)	Kutsauka kunobvumidzwa (mm)
4 - 10	± 0.15
>10 – 30	±0.30
>30 – 50	± 0.40
>50	± 0.8%

3.4 Kushivirira ukobvu hwemadziro

Ukobvu hwemadziro (mm)	Kutsauka kunobvumidzwa
≤1.0	± 0.12 mm
>1.0 – 5.0	±10%
>5.0	± 8%

3.5 Zvinodiwa pakutwasuka

Dhayamita yekunze (mm)	Kukombama kwakanyanya pakureba kwemita imwe neimwe
4 - 8	≤ 3 mm
>8 – 10	≤ 2 mm
>10	≤ 1.5 mm

Cherechedza: Kune machubhu ane dhayamita yekunze ye20-90 mm, kutwasuka kwakasimba kunodiwa≤ 1 mm pahurefu hwemita imwe neimwezvinogona kubvumirana.

IV. Kuverenga Kurema Kwedzidziso

GOST 8734-75 inoshandisa fomura inotevera kuverenga huremu hwedzidziso pamita imwe neimwe yechubhu:

M = 0.02466148 × s × (Dₙ − s)

Kupi:

M= huremu pamita (kg)

Dₙ= dhayamita yekunze yezita (mm)

s= ukobvu hwemadziro (mm)

Kuwanda kwesimbi= 7.85 g/cm³

Chinyorwa chakajairika chinopa matafura akazara ekurema kwemusanganiswa wese wedhayamita yekunze uye ukobvu hwemadziro kubva pa0.3 mm kusvika 24 mm. Mienzaniso:

Pamadziro e30 mm OD × 2.5 mm, huremu hwepfungwa ≈ 1.696 kg/m

Pamadziro e76 mm OD × 4.0 mm, huremu hwepfungwa ≈ 7.102 kg/m

V. Magiredhi eSimbi Anowanikwa

Zvichienderana neGOST 8733-87, machubhu asina musono anodhonzwa nechando anogona kugadzirwa kubva mumhando dzakasiyana dzesimbi yekabhoni nesimbi ye alloy:

Giredhi resimbi	Rudzi	Kushandiswa kwakajairika
Giredhi 10, Giredhi 20	Simbi yemhando yepamusoro yekabhoni	Kutakura mvura, maumbirwo akajairika
Giredhi 35, Giredhi 45	Simbi yemhando yepamusoro yekabhoni	Kugadzirwa kwemichina, zvikamu zvechivakwa zvine simba guru
09Г2С (09G2S)	Simbi isina chiwanikwa chakawanda	Basa rekupisa kwakaderera, zvivakwa zvine simba guru

Kuenzana kwenyika dzese: GOST 8734-75 machubhu asina musono anodhonzwa achitonhora akafanana zvikuru mukugadzirwa uye kushandiswa kwawoASTM A519(machubhu emakanika asina musono ekabhoni uye alloy steel).

VI. Minda Yekushandisa Yakajairika

Kutenda kunakunyatsorongeka kwepamusoro-soro, kupedzisa kwepamusoro kwakatsetseka uye kugadzikana kwakanaka, GOST 8734-75 machubhu asina musono anodhonzwa nechando anoshandiswa zvakanyanya mu:

Munda wekushandisa	Mashandisirwo chaiwo	Sei wakasarudza
Michina chaiyo	Mishave chaiyo, masirinda ehydraulic, zvikamu zvepneumatic	Kururama kwakanyanya, kutarisisa zvakanaka
Masisitimu eHydraulic & pneumatic	Mapaipi emafuta ane simba guru, mitsetse yemhepo	Nzvimbo yemukati yakatsetseka, kuramba kuyerera kwakaderera
Indasitiri yemotokari	Machubhu ekudzikisa kuvhunduka, machubhu egiya rekufambisa	Kufanana kwakaenzana kwezvikamu
Kemikari yePetrokemikari	Machubhu ezvishandiso, mitsetse yekuteedzera	Kudzvinyirirwa kwakavimbika
Kugadzira magetsi	Mapombi ekubatsira ebhoira	Kushanda zvakanaka pakupisa kwepamusoro

Zvichienzaniswa nemachubhu anoputirwa nemoto, maitiro ekudhonzwa nechando anoita kuti machubhu eGOST 8734-75 ave nani mu:

Kururama kwehukuru: OD tolerances dzakasimba se ±0.15 mm (saizi diki), zviri nani pane hot-rolled.

Hunhu hwepamusoro: Yakanyatsonaka mukati nekunze - yakagadzirira kugadzirwa nemazvo pasina mamwe machining.

Kunyatsotarisa: Ukobvu hwemadziro hwakafanana, hwakakodzera kugadziriswa nemazvo.

VII. Kuenzana Kwemupimo Wenyika Dzepasi Pose

Sisitimu yakajairika	Muyero unoenderana	Tsananguro
China (GB)	GB/T 3639-2021	Machubhu esimbi asina musono anodhonzwa nechando kana kuti anotonhorera
USA (ASTM)	ASTM A519	Machubhu emakanika ekabhoni nesimbi isina musono
Russia (GOST)	GOST 8734-75(zviyero) +GOST 8733-87(mamiriro ehunyanzvi)	Zvinoshandiswa pamwe chete

Chinyorwa chekuenzana: Chiyero cheChinese chiri pedyo zvikuru neGOST 8734-75 ndecheGB/T 3639-2021(Machubhu esimbi asina musono anodhonzwa kana kuti anotonhorera), anoenderana mukushandiswa (kushanda kwakanyatsonaka kwechando) uye mukugadzirwa. Pamusoro pezvo, GB/T 8162 (machubhu asina musono anogadzirwa) uye GB/T 8163 (machubhu asina musono anofambiswa nemvura) anogona kutariswa, asi GB/T 3639 inopa mukana wakanakisisa mukushanda kwakanyatsonaka uye kushanda kwakadzika.

VIII. Sei Uchifanira Kusarudza Sanonpipe?

Zvakanakira zvedu	Zvidimbu
Unyanzvi hwemazuva ose	Kunzwisisa kwakadzama kwehurongwa hweGOST 8733/8734 - tinodudzira nemazvo zvese zvinodiwa zveRussia
Vimbiso yezvinhu	Mhando dzose dzemagiredhi akafukidzwa - 10#, 20#, 45#, 09Г2С, nezvimwewo, nezvitupa zvakakwana zvekushandisa.
Kunyatsojeka kwakavimbiswa	Machubhu ese akagadzirwa zvichienderana nezvinodiwa neGOST 8734-75 - kurongeka kwakavimbika kwehukuru hwayo
