Haizoshandisi dzakagadzirwa simbi: mhando dzavo dzose

Panguva magadzirirwo uye kuvakwa Mapaipi pfungwa inobhadharwa nezvechiratidzo uye musono majoini senyere pamwe diameters zvakasiyana. In zvikamu chisimbiso akashandisa remubatanidzwa unonzi kuchinja simbi uye nokubvumira vakasununguka unyatsoshanda kushanda nzvimbo vose kumativi. Izvi zvinhu muzviitiko zvakawanda kwakakurumbira chaizvo. Vagadziri Russian pave mureza simbi kuchinja maererano GOST 17378-2001 uye kushandiswa kuchinja tsitsi panguva majoini, haishandi Standardization parameters. Kune mhando mbiri mavharuvhu hwaishandiswa pombi vari paanoiswa: asi eccentric uye concentric.

Kana wokutanga, vanoshanda Inlet uye nzira yokubudisa nokuda Urume chokubuda akabatana ne mari duku, izvo vanogona kufurira aibuda motokari. Pano, rezasi inova nzvimbo kubatana.

Kana yechipiri, kuchinja simbi concentric sepombi anobatsira pokunamatidza majoini pasina misha pamwe akabatana rwekuita dziriko.

Yerera achipfuura munharaunda akazaruka ari Mapaipi panguva chinguva, kuwedzera kana kunodzikira, saka anoita nekubata kufurirwa. Izvi zvinobva kuchinja kwakaita sesimbi.

Mashoko nokuda kugadzirwa ari mavharuvhu zvakasiyana simbi mamakisi. Nokuti kushanda mu pasi kumanikidzwa ezvinhu uye non-kungatikanganisa simbi kuchinja zvinoitwa kubva kabhoni simbi St3, St10, St20. zvigadzirwa izvi rakapa kubva simbi mamakisi zvakadai 12X18H10T, 15X5M kushandisa kana kutakura hasha zvinwiwa aibuda mune chaiyo simbi nziyo anowedzerwa kuvandudza ngura kurwisa mukurumari. Of simbi ine pasi ngura nemishonga kuchinja kubereka simbi ine zingi unhani mumwe rukoko.

Chinhu chinokosha chinoratidza chisimbiso ndiyo kunonyanyisa nokushanda kufurirwa zvichienderana acho uye geometrical parameters kukurira uchishandisa nevamwe kuwanda 4 kusvika 160 MPa, zvakafanana kunonyanyisa zvinobvumidzwa.

Kuchinja welded simbi yakagadzirwa kushanda pane imwe kumanikidzwa 16 MPa uye kudzvinyirirwa dzimwe tembiricha -70 kusvika + 450 ° C, uye husingakwanisi tembiricha uye kumanikidzwa musiyano.
The huripo kugadzirwa michina kungaita rebar nzira tsika kana achidzinga Centrifugal electroslag, kuwana nayo miganhu, ichiwedzera akavimbika uye upenyu basa.

Zvinodiwa kuti zvinhu chakakodzera uye neungano nemirayiridzo:

- the simbi inofanira kuva mukuru ductility, mamiriro svarimostyu uye kuoma ;

- makomba abvume proportionality Kuchinja nenyere roundness uye ndege magumo zviso.

Kusarudza simbi kuchinja, tinofanira kuomerera zvinotevera nzira:

- Inlet uye nzira yokubudisa nenyere dhayamita;

- mhando zvokunyama uye simba raro zvivako;

- kuona kushanda svikiro uye tembiricha musiyano;

- Operating nevezera.
