Kana uchida kuziva rumwe ruzivo, senge mitengo, zvigadzirwa, mhinduro, nezvimwewo, prenditaura nesu online.
1. Kupatsanurwa kweZvinhu
| Chinhu | Zviri Mukati | Tsananguro |
|---|---|---|
| GOST 8732-78 | Mhando dzakasiyana-siyana uye mwero wekusanganiswa kwemapombi esimbi asina musono anopisa | Inotsanangura dhayamita yekunze, ukobvu hwemadziro, kureba, nezvimwewo. Inoshanda kumapaipi asina musono anokonzerwa nekupisa kunotenderera (kupisa kunochinja). Rudzi rweOD rwakajairika: 32-426 mm; ukobvu hwemadziro sezvinodiwa. |
| GOST 8731-74 | Mamiriro ehunyanzvi akajairwa emapombi esimbi asina musono anopisa | Inotsanangura kuumbwa kwemakemikari, hunhu hwemakanika, nzira dzekuyedza, mitemo yekuongorora, nezvimwewo. Mitemo miviri iyi inofanira kushandiswa pamwe chete kuti igadzire tsanangudzo yakazara yechigadzirwa. |
| 30KhGSA (30ХГСA) | Chigadzirwa chesimbi cheRussian alloy structural steel grade | Simbi yesimbi ine kabhoni iri pakati nepakati ine simba rakawanda uye kusimba kwakanaka. Inoshandiswa mumichina, maindasitiri emauto, mundege, nezvimwewo. |
| B | Zita rekuti "kirasi" repombi | Chiratidzo chegiredhi muhurongwa hweRussian standard (hwakafanana nePSL1). Zvinodiwa chaizvo zvinofanirwa kusimbiswa nemagwaro ehunyanzvi uye ruzivo rweodha. |
2. Chiyero neZvinhu Zvakafanana zveChinese
Zvinhu zvakaenzana zvakananga: 30CrMnSiA (GB/T 3077 - Simbi yekuvaka yakagadzirwa neAlloy)
Zvakafanana zvizere uye zvinogona kunzi chinhu chimwe chete. Kuenzanisa kwemakemikari:
| Chinhu | 30KhGSA (30ХГСA) | 30CrMnSiA | Cherechedza |
|---|---|---|---|
| C | 0.27 – 0.34 | 0.27 – 0.34 | Kabhoni yepakati |
| Si | 0.90 – 1.20 | 0.90 – 1.20 | — |
| Mn | 0.80 – 1.10 | 0.80 – 1.10 | — |

| S | ≤ 0.025 | ≤ 0.025 | — |
| P | ≤ 0.025 | ≤ 0.025 | — |
Hunhu hwemakanika hunoratidza:
Simba rekudhonza: ≥ 420 MPa
Simba rekupa: ≥ 235 MPa
Kureba: ≥ 24%
Kusimba kwemhedzisiro: ≥ 35 J/cm²
Kuoma: ≤ 207 HB
3. Dudziro Yakajairika
GOST 8732-78
Kureba kwehukuru: OD 32 - 426 mm, ukobvu hwemadziro 2.5 - 75 mm (mamwe masosi anoratidza kusvika 75 mm)
Kureba: Kazhinji 4.0 - 12.5 m
Magiredhi esimbi anoshanda: Zvese simbi dzekabhoni nedze alloy (semuenzaniso, simbi ye alloy 12Kh1MF, nezvimwewo)
GOST 8731-74
Kureba: Mapaipi esimbi isina musono anoshandiswa zvakanyanya esimbi dzekabhoni nesimbi dze alloy
Zviri mukati: Kuumbwa kwemakemikari, hunhu hwemakanika, nzira dzekuyedza, mitemo yekuongorora, zvinodiwa pakurapa kupisa, nezvimwewo. Zvinofanira kushandiswa pamwe chete neGOST 8732-78
4. Zvinhu Zvikuru Zvinofanira Kufungwa Nezvekugadzirwa
Chinhu ichi isimbi yemhando yepakati-kabhoni inoda kudzorwa kwakasimba kwemaitiro acho. Nyatsoteerera:
4.1 Kudzora Zvinhu Zvisina Kugadzirwa
Zvidimbu zvinofanirwa kugadzirwa nemaruva akatenderera esimbi. Nyatsoongorora makemikari kuti zvienderane nezvinodiwa (S & P shoma kudzivirira kutsemuka).
Sarudza mabhiritsi kubva kumagayo makuru ane ruzivo rwesimbi ye alloy (semuenzaniso, Baosteel, Valin Steel, Hengyang) zvichiita kuti zvive zvemhando yepamusoro mukati (gasi shoma, zvinhu zvishoma zvinosanganisirwa).
4.2 Kudzora Kupisa Tembiricha
Tembiricha yekupisa yezvikamu zvebhiriji: 1150 - 1250 °C; ona kuti tembiricha yakafanana kubva pakati kusvika pamusoro kudzivirira kupisa zvakanyanya kana kupisa zvishoma.
Dzora nguva yekudziya uye mamiriro ekunze kudzivirira kubviswa kwekabhoni pamusoro (zvinokanganisa kuomarara uye kusimba kwenzvimbo).
4.3 Kudzora Kuchinja & Kuumba
Kudzora kufanana kweukobvu hwemadziro kuitira kuti OD uye kushivirira kweukobvu hwemadziro zvienderane nezvinodiwa zvakajairwa.
Pakuboora, shandisa chidimbu chidiki usati waisa chivharo kudzivirira zvikanganiso zvemukati zvakaita sekunge mapete kana kuti maburi.
4.4 Kurapa Kupisa (Kwakakosha!)
30KhGSA isimbi inodzima uye inodziya ine kabhoni iri pakati nepakati - inofanira kudzima + kudziya kuti iwane hunhu hunodiwa. Mushure mekudzima nekudziya, inoratidza simba rakawanda uye kusimba kwakakwana. Zvinodiwa pakurapa kupisa: kudzima pa880 °C, kutonhora kwemafuta; kudziya pa540 °C, kutonhora kwemvura kana mafuta. Hunhu hwemuchina mushure mekurapa kupisa hunofanirwa kuyedzwa zvakanyanya zvichienderana nechiyero.
4.5 Kuongorora Hunhu
Kuyedza kusingaparadze: Zvichienderana nezvinodiwa, pombi yega yega inofanira kuongororwa nekuyedza kwe ultrasonic (UT) kana eddy current (ET).
Kuongororwa kwemidziyo yemakanika: Mienzaniso inofanira kutorwa pachikamu chimwe nechimwe chebvunzo dzekudhonza, kurovera, kupwanya/kukombama.
Kuongorora nekutarisa: Pombi yega yega yakaongororwa kuti ionekwe kana paine OD, ukobvu hwemadziro, kureba, mhando yenzvimbo, bevel yekupedzisira, nezvimwewo.
5. Zvikumbiro & Zvinodiwa zvekutumira kunze kwenyika
Mapaipi asina musono echinhu ichi anonyanya kushandiswa mundege, kugadzira zvechiuto, mainjiniya emakanika (kushandiswa kwakasimba), pamwe chete nemashaft anorema, magiya, ma compressor blades, nezvimwewo.
Pakutumira zvinhu kuRussia, zvinodiwa kuti zvitevedzerwe neEurasian Customs Union Technical Regulation TR CU 032/2013 (Safety of Pressure Equipment). Zvinokurudzirwa kusimbisa zvinodiwa zveEAC certification nemutengi pachine nguva uye kusanganisira rutsigiro rwehunyanzvi rwakakodzera mukotesheni.
Kana mutengi akapa simbi yemhando yepamusoro uye chiyero chete pasina kutaura OD, ukobvu hwemadziro, kureba uye huwandu, tanga wakumbira ruzivo urwu usati watora kuti udzivise njodzi dzinotevera dzekushanda.
Pakupindura, taura zvinhu zvakakosha zvakaita sekusagona kupinza zvakanaka uye chitupa cheEAC kuratidza hunyanzvi.
