Lokulinganisa - ntoni na? Classification, kukhokela ukhetho kunye nokukhetha

Xa elungiselela iinkqubo kwamanzi kunye nokuzifudumeza, qiniseka ukuba asebenzise izilinganisi ukuba thaca namhlanje asolwa enkulu. Zisetyenziswa ukudibanisa iingongoma ekujikeni, eyayizalwa kunye ukuguquka. izinto ulwazi buyafuneka xa uqhagamshela imibhobho of ngobubanzi ezahlukeneyo. iindawo Ithagethi kuba data njengogwali zeplastiki ezinepolypropylene lwesamente okanye iinkqubo.

nokufakwa Classification ezinepolypropylene

Ukuba udinga likufanelekele ukuba kwingcamango enjalo, kufuneka uyazi. Ezi zinto zenza kube lula ukubeka inkqubo kunye elide, ukuvumela ukuba ukunika ukubukeka avule. Xa kuziwa izixhobo ezinepolypropylene, ukuba zihlelwe ngendlela fomu. Iintlobo ezahlukeneyo izinto bangaba iikona, phakathi kwabo ziphawulwe:

• clutch;
• indawo;
• tee;
• spider;
• kagesi;
• "American";
• umthe-;
• badlule.

Imibhobho ezidibene nge amaqhekeza esonka eziphathekayo kufanele ukuba ifane, njengoko kwimibhobho. Ukuba nkqubo iqulathe emikhulu, iglasi ifayibha lwesamente, nezinye iintlobo zemveliso ayinakusetyenziswa.

Ngamana kuba yimfuneko kunye ezinepolypropylene izixhobo, luqiniswe fiberglass. Umchiza lisebenza njenge amanqaku ngaphandle ezinepolypropylene kunye isinyithi okanye ezinye izinto. Kulo mzekelo, ilungu Screw in an "American" zingasetyenziswa.

Ukwahlukanisa ngu indawo

PVC izixhobo zingahlukaniswa kwakhona indawo. Kule uxhulumaniso kufuneka zenziwe nokufakwa:

• Tye.
• T-ezimile.
• Y-ezimile.

Bathi izixhobo kwakhona nge uhlobo lonxibelelwano, zingakotshwa omthuqwa okanye ucinezelo. Crimp hlobo kumiliselwa iseti lokugqibela, ukongeza ukuqokelela akukho mfuneko. Xa sisondela uthelekiso kunye joint yayo nge welding, owokuqala has inzuzo. Njengoko izinto eziphambili zezi:

• lula ukufakwa;
• akukho mfuneko yokuba iwelding;
• ukukwazi ukufaka kuzo zonke iimeko zemozulu, njengoko ezi crimping lwezilinganisi ezinepolypropylene Musa ukoyika amazinyo amaqondo obushushu;
• ukunqongophala kwezakhono ezifunekayo ukuze kuqokelelwe lwezilinganisi ucinezelo.

Indlela ukukhetha izixhobo welding eziqhagamshelayo

Xa uluhlu esikhulu kwimarike namhlanje limelwe ofanelekayo. Ntoni kwaye usebenzise apho lwesi sakhi, ungabona ukuba ufunda inqaku. Xa indima omnye kakhulu ezilula izixhobo izenzo nokuhlangana, apho kuyimfuneko ukudibanisa emancamini omabini ezisendleleni. Ingasetyenziswa ukuba ukuwelda kunye nemibhobho eziqhelekileyo lwesamente.

Le misebenzi yenziwa nge-Push-kufanelekile. Ke phakathi izifakelelo ziyakwazi ukuchongeka nkqu iikona, nabaqokeleli-, kunye Tees. Xa ukhetha le tee kufuneka ahlawule ingqalelo yokuba ibe inguqu okanye elula. Kwimeko yokuqala, ungenza lenguqu ukuya enobubanzi eyahlukileyo.

Ukuze ufumane amacebiso ngokukhetha

Xa usebenzisa unikezelo lwamanzi eshushu okanye ebandayo, isixhobo sokuqokelela kufuneka kukhethwe, enokusetyenziselwa ukudibanisa abaqokeleli ezininzi ukuya kumthombo ubushushu. Maxa wambi kuye kuthi yongezwe kwemithambo ibhola, leyo likhusela ngokuchaseneyo umhlwa.

Xa umntu onamava kufuneka kufanelekile oko kukuthi nokuba loluphi na uhlobo kunjalo, kufuneka azi ngokuqinisekileyo. Umzekelo, ukuba sishintshe conduit 90 imfuneko ° ikona. welding wayo lwenziwa yi usikrobana, ezi zifundo lubonisa izinto zokufudumeza neempawu eziwafaka ngokufaka enye ukuya kwenye.

nokufakwa Classification steel

izixhobo Steel zingahlukaniswa ngokwengqibo, zibekiwe:

• yemiqadi yokuhlanganisa;
• Tees;
• nokufakwa kwayo;
• amaqhoshana;
• Imigudu.

Endaweni yokusebenzisa zabo kuchazwa eliphakathi connecting. Xa sithetha ngalo imfuneko ukuqhagamshela imibhobho le ubukhulu efanayo, kufuneka usebenzise iindawo ngqo, kungenjalo kufuneka Stock up on iinkcukacha sethutyana. Ukuba ndinodibaniso azinamsonto.

Njengoko indlela wokujoyina izixhobo zentsimbi kufuneka kwahlulwa ibe:

• ucinezelo;
• nokufakwa press;
• Push-nokufakwa kwayo;
• crimp;
• azinamsonto.

Ukuba ufuna i leligama yintoni le uyilo kuya kufunyanwa. Umzekelo, indlela eqhelekileyo yokudibanisa izinto ezivelileyo azinamsonto iinxalenye. Kodwa izixhobo ucinezelo namhlanje athandwa kakhulu kuba kulula ukufaka. Zinokusetyenziswa loqhakamshelwano imibhobho zezixhobo ezahlukeneyo. ngendlela Onemisebenzi na izixhobo yezihlunu, enokusetyenziselwa kwiintlobo ezahlukeneyo ipipi.

Imiyalelo ngokukhetha izixhobo yangaphakathi

izixhobo yangaphakathi ukuze ezenziwe ngezinto ezahlukeneyo. Ukuba ngobhedu, ngoko phambi kokuba izinto ukuba namhlanje ixhaphakileyo. Ubukho ring nokubotshwa lunikeza uphawu nayiphi ezimbaxa. Ukuba ufuna ukufikelela iipropati anti-umhlwa, kuyimfuneko ukuba ukhethe izifakelelo kunye ukutyabeka efunekayo xa siqhubana imibhobho.

Ukuba ufuna ukuthenga into kwi ngeendleko ezifikelelekayo, kufuneka ungakhetha izifakelelo zobhedu. Abekho phantsi nomhlwa kwaye akwazi ukusebenza ixesha elide. Ukuba ufuna ukutshintsha indlela sesindululo medium olusezimbizeni, kuyimfuneko ukuba afumane yeyantlukwano azinamsonto izixhobo. Kodwa ukwenza flow ukwahlukana point tee eziliqela ukuze kukhethwe.

Ukuba kuyimfuneko, ukwenza uqhagamshelwano kwemibhobho ezimbini zibe inkqubo kufuneka asebenzise iklatshi, i element ngokugqibeleleyo ezifanelekileyo ilungiselelo imibhobho izinto ezahlukeneyo. Kulo mzekelo, uya kuba nako ukudibanisa umbhobho weplastiki ku zezobhedu. Ezifakwe ukuba imibhobho yobhedu unako kwakhona impahla efana. Umzekelo, i plug nga sealingly ukuvala i nkqubo kwaye ukuvala isiphelo umbhobho. Ngamanye amaxesha le ngenxenye nje kuphela isetyenziswe kwiindawo zemisebenzi, kodwa into zokuhombisa.

Ukukhetha izixhobo ze imibhobho yobhedu, kufuneka wesuka kwabo ezenziwe umbandela enye, ngenxa yokuba i eside kakhulu, kulula ukufaka kwaye athembekile. Ukuphucula iimpawu ingubo sabo izinto ezikhethekileyo, phakathi kwabo:

• nickel;
• chrome;
• zinc.

Amaxabiso nokufakwa

Amaxabiso for PVC izixhobo ziya kwahluka ngokuxhomekeke element kuyo. Hi xikombiso, le ngcina "American" iya kuxabisa 119 miri., Ngoxa iglu okulula "American" ixabisa 105 engange. Emkhonweni enamathelayo kunciphisa iindleko engange-16, kodwa i plug -. 13 engange.

Ukuba ufuna izifakelelo PVC, ixabiso ngabo kufuneka ube nomdla. Umzekelo, isixhobo sokuqokelela kuza kubiza kakhulu, iindleko yi 804 engange., Kodwa umnqamlezo ixabisa 91 engange. Nokuhlangana ngcina liya kuxabisa imali engange-16. Down-enamathelayo bushing ixabisa engange-33. izixhobo zeplastiki thaca namhlanje uluhlu olubanzi, phakathi kwezinye izinto, kufuneka zenziwe ukunciphisa tee, ixabiso layo ngu 37 engange. Engela 90 ° iindleko miri 9 kuphela. obune.
