The njanji P 65: lakuti, maonekedwe, kukula

Maziko a Russian sitima maukonde mpaka njanji F 65 - liniya kapangidwe awiri T-gawo, yomwe kutumikira maganizo a katunduyo kwa katundu pakubwezeretsa, awo zotanuka "processing" ndi kulanda wotsatira ku thandizo - sleepers. Tsatanetsatane wa izi "matabwa zitsulo" malamulo GOST 8161-75. Kusonyeza kapangidwe ndi kukula kwa njanji kuzimitsidwa ndi unquenched ndi njanji akulankhula mokalipa mtundu R65.

Njanji 65 F

njanji aliyense amapangidwa kuti athetse mavuto angapo. Choyamba, iwo kuzindikira ndi kupereka katundu sitima. M'pofunika kusunga moyo wautali wa onse subgrade ndi matayala. Chachiwiri, iwo amapereka malangizo kwa kayendedwe ka anagubuduza katundu. Ndipo potsiriza, iwo kulenga nsanja ndi kukana wamng'ono mpaka anagubuduza la mawilo. Contact padziko ntchito zinthu ndi ochepa masentimita (3-5, malingana kalasi njira). Chithunzi cha nyumba liniya ankaimira mwachilungamo yaikulu. Choncho, njanji ya R 65, komanso R50, R75, ntchito atagona wa jointless mtsogoleri njanji gulu ndi n'zotsimikizira waukulu. Iwo ntchito polenga turnouts. Zikatero, liniya mankhwala ndi mbiri kusinthidwa (RK65).

zinthu za zii

Njanji R65, komanso mitundu ina, sitinganene kuti alipidwa I-mtengo. Akatswiri kudziwa panagona angapo ziwalo makonzedwe:

1. Mutu - mawonekedwe ake amapereka kugwira otetezeka anagubuduza mawilo ndi njanji yokha.
2. Khosi - kupewa kupinda akatundu, ndi transmits iwo thandizo dongosolo njanji.
3. Chokhacho - amapereka kukhazikika dongosolo lonse la liniya ndi kugawira nkhawa kudutsa padziko wogona ndi. Amakhala lamanja ndi kumanzere kwa kholalo.

Komanso, mwa madera awiri anapambulwa njanji oyenerera kumanzere ndi kumanja kwa khosi ndi agwilitse danga m'mphepete m'munsi mwa mutu midsole lapansi. Izi otchedwa lamanzere ndi lamanja nkusani. Iwo anakonza mphero oyika, amene kugwira njanji ya 65 R pakati njira m'madera ena.

njanji miyeso P65

Ochepa ndinadabwa chifukwa njanji P 65 ndi zoterezi mawonekedwe. Panthawiyi, aliyense utali wozungulira kupindika, dera lathyathyathya ndi otsetsereka osankhidwa empirically kapena kuwerengetsera kulenga zinthu mulingo woyenera mogwirizana ndi katundu kugudubuzika. Ambiri a ife tikudziwa kuti njanji P 65 kulemera wofanana makilogalamu 65, chimene chiri mochitika pachithunzichi. misa kweni kweni pa mita wa makilogalamu 64,72. Ena options ndi matanthauzo zotsatirazi:

• chikufa utali wozungulira (R500) zipangitsa ndi kukhazikika kwa katundu, i.e. mphamvu lifanane ndi olamulira kotenga wa njanji gudumu chitsulo chogwira matayala;
• R80 amalenga kusintha osalala R15, amene amalenga ndi kukhudzana wolimba ndi nkhafi ndikupita gudumu;
• kukondera mutu 1:20 limafanana ndi otsetsereka a gudumu flange kuti ndi koyenera kuti interfacing ndi Crest pa gudumu;
• utali wozungulira R3 nazo m'mphepete lakuthwa mutu wopangidwa kuthetsa nkhawa oweta;
• Transitional radii R15 ndi R370 anayambitsa pofuna aziphatikiza wa dera mutu-khosi ndi kuthetsa voltages woopsawo;
• R400 kusintha utali wozungulira patsinde pa khomo pachibelekeropo chofunika kwa katundu yosalala kusamukira yekha;
• biases chapamwamba ndipo m'munsi nkhope ya gawo yekha mutu ndi amodzi (1: 4), m'pofunika kukhazikitsa ndi mapadi mphero woboola pakati, ndi kuti imodzi kutumikira monga spacers lapansi.

Daily poyera kuti katundu lingamutsatire njanji 65. P ake kulemera makampani Russian sangathe saganizira. Koma ngati si kwa kapangidwe wapadera, iye sakanakhoza kupirira ntchito mwamsanga kuwalepheretsa ndipo anafunika m'malo.

zitsulo njanji

njanji onse njanji (65 R, RK65, P75, P50) anapangidwa yekha wa zitsulo ndi njanji. Iwo ali mphamvu mkulu kupinda, kuuma ndi kuvala kukana, amene zimatheka ndi mkulu mpweya okhutira (0.82%) ndi kuwonjezera dopants - manganese, vanadium, zirconium, pakachitsulo, titaniyamu. M76VT - mtundu zoyamba za zitsulo, ntchito kupanga akulankhula mokalipa njanji. Malinga njira yokonza, zingakhale woyamba (fusible basi mu ng'anjo otsegula moto) kapena gulu lina. Osewera kapena laminated "nkhumba" amapitirira zovuta multistage kutentha mankhwala sitepe. Makamaka chifukwa ichi pa R njanji 65 mtengo ndi mkulu - rubles zikwi 50 pa tani ..
