Ubomi inkonzo yezikhala Screw laziseko

unqwabelana Screw ngoku isetyenziswa kakhulu yokwakhiwa izinto zesiseko amakhaya abucala kunye nokwakhiwa elikhulu-scale izibonelelo mveliso. Uyazixhasa azinike yale hlobo melene umthwalo omkhulu kwaye emva kokuba izakhiwo kuqhubeka ethwaxwa umonakalo ngeemeko zokusingqongileyo. Kungenxa yoko le nto ngoku abaninzi bezibuza ukuba iyavakala ukusebenzisa zitsho esijijwayo, nokuba ubomi ezi zinto ezikhoyo ngokubanzi isakhiwo bufutshane kakhulu?

A incinane

Kwenqwaba uhlobo Screw wabonakala malunga 200 kwiminyaka eyadlulayo. Lonke elo xesha, ukuba ezisetyenziswa kakhulu ukwakhiwa iibhulorho, piers, iinqaba, iintambo zombane, kunye nezinye iisayithi ezininzi ezinkulu. Kukho ubungqina kakhulu ukuba ubomi inkonzo yezikhala Screw kunokuba ukuya kwiminyaka eli-150. Umzekelo, pier nangoku akazange ziwile, leyo umi emanzini olwandle kwi exhasa ezifanayo ngaphezu kwenkulungwane enesiqingatha.

Kukho imin yonke, apho iindwendwe bona buqu iincam yokuqala yezikhala iqhosha lemenyu. Noko ke, konke oku akuthethi ukuba isakhiwo metal iya kuhlala ngonaphakade. ukubuyekeza ezimbi ngobomi inkonzo yezikhala Screw kakhulu kufanelekile, njengoko eziveliswa ngenkxaso onobu bugcisa bukhethekileyo unikwa ngokwenene ngokukhawuleza ukuyisonga. imibutho yenkxaso technology lemveliso iphawulwa eninzi kujonge izinto kunye awohluke. Ukuba imigaqo zemveliso aye anyhashwa, ngoko ke imfumba igqityiwe kwaye musa bakhonza yesithathu kwexesha ebhengeziweyo. Ngoko ke kubaluleke kakhulu ukuba banikele ingqalelo kule nkcukacha xa kukhethwa yoyilo isiseko.

Ubomi inkonzo GOST

Ngokutsho imithetho karhulumente ebomini yezikhala Screw uvela kwiminyaka engama-60 ukuya kwezili-120. Kwakhona, le datha ilandelayo axeliwe ku ISO:

• Electromechanical ngesinyithi senzeka emhlabeni ngeqondo of mm 0,02 ukuya 0.05.
• Udonga Ebubanzini Screw kunye nenkxaso ngokwayo ayikho ngaphantsi kwe 5-6 mm.
• Kutshabalala imibhobho zodonga ngereyithi eyi-5 mm / 0.5 s = 100.

Ukongeza, yamakariti zizele Polymer ukubunjwa eyodwa uhlobo yokubini, leyo kugcina iimpawu zabo kwiminyaka 7-15. Oku kuya kwandisa ubomi yezikhala Screw laziseko. Ukuba ngaba ezi zinto zaye anyhashwe kwinkqubo wokwenziwa izixhaso, imveliso iya kuba oluthembekileyo yaye ixesha elide.

Ingaba kukho umahluko phakathi cast kunye tips esijijwayo ukuqhuba nge welding

Khange kubekho umahluko omkhulu phakathi kwezi mveliso. lugs wabumba zenziwe of 35L ngentsimbi standard zokumakisha. Umahluko omkhulu phakathi kwezi zinto sixhasa kukuba umgca helical akukho welding, cone igoqo wazidiba kwaoko nabo. Noko ke, bambalwa abantu bazi ukuba enyanisweni lugs cast welding kumbhobho. Oku kuthetha ukuba ukusetyenziswa kwayo akukho uyayeka ukuba siphephe welds.

Ukuba sithethe ngayo iintsilelo lugs Yamxuluba, xa imveliso yabo kuyimfuneko ukulawula inqanaba nomgangatho aqiniseke. Ukongeza, imveliso yazo akunakwenzeka ngaphandle ukusetyenziswa kwezixhobo ultrasound. Inyaniso yokuba izinto imveliso usenokuba iintanda ezincinane, pores kunye mgodini, nto leyo eya kunciphisa kakhulu iimpawu amandla ukuqina zitsho Screw kuyo.

tips iwelding ukuqinisekiswa ngokuzimeleyo, njengoko nkqu uhlolo olubonakalayo, kunokwenzeka ukuvavanya umgangatho ukuveliswa kwemveliso le. Kwemoto kunye imigca waphosa phantse-25% enganeno.

Ingaba kukho umahluko phakathi beqabe kwaye kwalenza inqwaba amacebo

Umahluko ephambili axhomekeke kwinkcaso umhlwa. Ngokutsho izimvo ezininzi, ebomini Screw amathumba, ipeyinti ngayo izinto ababhalisiweyo angaphantsi kakhulu ngenxa impembelelo kokusingqongileyo ndlongondlongo. ngeso lenyama zothintelo ngokwaneleyo ubuninzi engama-15, emva koko iimveliso yesinyithi baqalisa ngokukhawuleza wambu irusi.

Unqwabelana, udlule yediphu galvanizing inkqubo eshushu, kungekhona phantsi umhlwa kwiminyaka 40-50. Noko ke, konke oko kuxhomekeke ndlongondlongo zomhlaba. Ngenxa indlela hot-dip galvanizing umaleko senziwa ngendlela Ebubanzini 0.2 mm phezu imfumba, nto leyo ingasetyenziswa ixesha elide. Ngaphezu koko, umaleko ibakhusela zinc akuxhomekekanga ukuyisusa ngexesha kokujikeleza inkxaso.

Kwakhona sinikele ingqalelo iindleko iimveliso. Inkxaso, elidlulileyo ashushu-dip galvanizing, iya kuxabisa-25% ibiza ngaphezu iimveliso baphathwa kunye ipeyinti kunye ivanishi.

Yintoni kuchaphazela ngokonakala ukuqina

Igama elithi yenkonzo isiseko phezu kwemoto Screw ukuba kakhulu yancitshiswa ngenxa zinto zilandelayo:

• Impembelelo ihamba umhlaba. Phantsi kweemeko eziqhelekileyo, umhlaba mpembelelo incinane yamakariti iqhosha lemenyu. Noko ke, xa sithetha malunga neemeko ezigqithisileyo kunye nokwanda nokushukumisa umhlaba, oko kuchaphazela iimpawu yokusebenza iibheringi.
• ukusebenza emhlabeni. Ngenxa zonyaka ubushushu ukuhla otyhidiweyo linciphise ngokuqhubekekayo kwaye lwandisa nesakhiwo sayo iphazamisekile. Ebizwa amandla isekela lifinyele ngokubonakalayo ukususela neentanda eziphathekayo kunye pores. Xa usebenzisa ngemoto ezikumgangatho ophezulu, inani kuxhotyiwe ukuqanda thawing leyo ngokwanele iminyaka ukuya ku-120 ubudala, ngathi oku kuyenzeka.
• nokumelana Chemical. Ukuba inqanaba ubumuncu bomhlaba wedatha, umhlwa yasekelwa ndozolulela ngokukhawuleza kakhulu.
• nokumelana Electromechanical. zokulimala kwenzeka phantsi njengeemfumba olomeleleyo igcwala ngenxa imisinga uqhuzu ezinokuthi zifakwe nokwakheka komhlaba. Amaninzi ubunzima ekuthwaleni umhlwa electro, akhiwe kufutshane iingcingo ezihamba phantsi komhlaba okanye amaziko mveliso ezahlukeneyo.

Indlela ukuba sandise ubomi yezikhala iqhosha lemenyu

Kukho iindlela ezininzi ezinokuthi ukunceda ukwandisa "nobomi" isiseko leyo ifakiwe kule hlobo lwenkxaso:

1. Sebenzisa unqwabelana ngeendonga eqinileyo. Wonke aphindwe ngesinyithi kwandisa ubomi wenkonzo malunga ne-15 iminyaka.
2. Sebenzisa izixhaso ezenziwe ngentsimbi exutyiweyo kuphela. Unqwabelana kufuneka ziphathwe iikhompawundi ezikhethekileyo ezithintela imichiza umhlwa.
3. Ukuba imveliso akukhuselwanga nxamnye irusi, kufuneka yokugubungela umhlwa ezabo iikhompawundi zabo zokuthintela.
4. Khupha concreting of shaft embilwini. Le nkqubo ukukhusela isakhiwo nxamnye ukufuma nokuphucula elibizwa amandla ngenkxaso.

hayi Kucetyiswa ukuba basebenzise izixhobo ifuthe ngexesha lofakelo yingqumba. Oku kuzakugcina isakhiwo imveliso nokwandisa ubomi nenkonzo yabo. Ukuba ukufakela yamakariti lwaqhutywa ngokungqinelana nemimiselo, inkxaso iya kuhlala ukuya kutsho kwiminyaka eli-100.

Izinto eziluncedo yezikhala iqhosha lemenyu

Phezu kwazo nje iingxaki ezinokuthi zivele ngexesha ukusetyenziswa kwale hlobo lwenkxaso, basaqhubeka ngokufuthi isetyenziselwa ukwakhiwa kweziseko kunye nokwakhiwa kwezinye izakhiwo. Oku kungenxa iingenelo zilandelayo yezikhala Screw:

• Isiseko medium size of zingafakwa kwi thuba lifutshane kangangoko ixesha (iintsuku kungekho ngaphezulu kwe 1-2).
• imali isiseko yehliswe phantse phakathi, ukuze ukwakhiwa kwazo zonke izibonelelo ziya kuba sitshiphu.
• Screw kwemoto zizinto ezilungele ukusetyenziswa emhlabeni ezingazinzanga.

UPawulos

Ukwazi inyaniso malunga ezitshomini yezikhala esijijwayo, kunokwenzeka ukuba ukwakha isiseko ixesha elide, ethembekileyo kunye engengomanzi ixesha analo lifutshane. The main imeko - kugcinwe inkqubo zeteknoloji woveliso leepali kunye nokufakwa echanekileyo iimveliso.
