Area umbala amashubhu - ikakhulukazi etafuleni kanye nezincomo

amashubhu Paint yinqubo saziso, edlala indima, hhayi nje kuphela ngenxa yobuhle, kodwa futhi bandisa ukuphila iphayiphi. umsebenzi Paint eyenziwa okudlekayo ezifana primer kanye upende. Kodwa indlela ukunquma malini badinga futhi anayo, futhi insalela ishiywa? Kuba nzima nakakhulu ukwenza lokhu uma uhlela inani elikhulu lomsebenzi, isibonelo, ukucutshungulwa zokuxhumana ku esiteshini wokusabalalisa. Ukuze abale kahle inani upende odinga ukukwazi endaweni umbala ipayipi. Ukuze ufunde indlela ukubala ke, sizobe ukukhuluma okwengeziwe.

izinhlobo amapayipi

Okokuqala, kufanele kuphawulwe phezu ukusetshenziswa upende kuzohambe- hhayi kuphela ubukhulu amapayipi, kodwa futhi isimo sabo begodu nesakhiwo impahla okuvela ngazo zenziwa. Ngokwesibonelo, enamathela imikhiqizo bushelelezi futhi lukathayela sinye kuzodinga amanani angalingani ezinengilazi.

Inqawe ungaba ukuma ezahlukene kakhulu kanye nosayizi sigaba. Kuye lezi nemingcele, kunqunywa i-scope ne operation imikhiqizo ipayipi. Uhlobo oluvame kakhulu amashubhu cylindrical nge isiyingi cross-section, kuvame kakhulu ukuba kusetshenziswe i-ukwakhiwa amapayipi kanye negesi amapayipi.

Uhlobo ethandwa metal ukwakhiwa kukhona ipayipi profiled kokuba ingxenye engu- ngaphandle isiyingi. Zingaba okusaqanda, isikwele elingunxande. Phakathi kwabo kukhona ozimele izakhiwo, izakhiwo ezahlukene metal, iphansi futhi nezipani.

tube lukathayela nge cross kwesigaba round asetshenziselwa ukwakhiwa komhlaba pressureless ekhaya nasezimbonini indle, isiphepho endle.

Kukhona tube Isigaxa-okwenyanga. Ahloselwe pressurization izinhlelo.

izilinganiso

Ukubala inani kapende izinto ngezindlela ezimbili: usebenzisa itafula ekhethekile noma ngokusebenzisa amafomula weJiyomethri. Futhi eqinisweni, futhi kwelinye icala, kuzomele wenze izilinganiso olunembile umkhiqizo.

Uma kukhona ithebula umbala amapayipi square, akudingeki kuphela ukuthola kulo isikhundla nemingcele efanayo ntathu njengoba etholwe kusuka izilinganiso, futhi umbono inki ukusetshenziswa noma primer. Ukubalwa usebenzisa amafomula - more xaka, kodwa akukho indlela ayisasebenzi. Ukuze ubone ukuthi umbala endaweni ipayipi ukuma ethize nesigaba cross, ifomula efanele.

amashubhu cylindrical

Ukuze wenze izibalo, kubalulekile ukwazi ubude ipayipi kanye engaba saso. Ubude kukalwa ngamamitha zebanga - ngamamilimitha. Sebenzisa le ndlela elandelayo:

S = 2 x π * R x L, lapho:

• S - ipayipi ndawo zaveza;
• π - pi elilingana 3.14;
• R - engaba;
• L - obuphelele.

Ngokwesibonelo, lapho ubude tube ka 10 m kanye ububanzi of 60 mm, surface area yayo kungaba 1,88 sq. m.

I kwesibalo efanayo ibalwa, futhi Umbala endaweni yokuchitha indle amapayipi. I ukuphela komehluko owawukhona ngalezi ezakhiwe makhulu. Ngokwesibonelo, e indle imithombo ubukhulu kungenzeka 70-200 cm Ezimweni ezinjalo, ngesisekelo ukuphakama esezingeni mikhiqizo -. 90 cm.

Area iphrofayela Umbala ipayipi

Ukuze ubone ukuthi ukubaluleka isithakazelo kuyadingeka ukwazi:

• ukuphakama uhlangothi ipayipi (H);
• ukuphakama Ngakolunye uhlangothi (W);
• Ubude (L).

Izibalo zenziwa kusetshenziswa le ndlela elandelayo: S = 2 x H x L + 2 x W x L. Ngokwesibonelo, lapho ubude ekuphakameni 10 m futhi izinhlangothi - 10 no-5 cm, le ndawo camera kungaba 3 sq. amamitha.

Square ngamapayipi ensimbi umbala oyindilinga

Ngo amapayipi nge Isigaxa izinyathelo ufushanisiwe nemingcele ezilandelayo:

• Ubude (L);
• ububanzi we umbuthano ezincane (ngo-R1);
• ububanzi we umbuthano emikhulu (R2).

Ukuze sithole isikhala semibala isicelo amapayipi ifomula S = 2 x π x-R1 x L + π x (ngo-R1 x-R1 + u-R2 x-R2). Ngokwesibonelo, uma ubude design kuyoba 10 m, kanye radii ayalingana 3 kanye no-6 cm, endaweni Imininingwane imayelana 2 amamitha.

amapayipi lukathayela

Ngo imikhiqizo efana siyisinqumo esinzima kunazo zonke ukubala ngokunembile indawo ephindwe, ngoba kungenziwa wadonsa eduze obuphelele. Ukuze kube lula ukubala, wonke amanani atholakala kule izilinganiso, kungcono ukukhipha ngokubhala ngesimo itafula.

Ngakho, isidingo usethe nemingcele ezilandelayo:

• engaba ugobile (A);
• flat kwelivi izingxenye ku ubude ubukhulu (B, D);
• Isinyathelo usayizi corrugations (C);
• engela ingxenye bushelelezi (E);
• ukuphakama ingxenye lukathayela (F);
• Umkhiqizo ukudweba umugqa (G).

Ngo isibonelo esikhethekile, cabangela indlela ukubalwa kwenziwe. Ngokwesibonelo, ukubaluleka A ilingana 3 mm. Ukuze ubone ukuthi ubukhulu ingxenye oyindilinga formula 2 x π x A isetshenziswa Ngakho, 18,84 mm. D value kufanele kabili, makube elilingana 20 mm. Ngokusekelwe idatha ngenhla, umuntu angakwazi ukuhlonza ubude corrugations efomini welulela - 38,84 mm.

Ukususa enyakazayo, Yekhompyutha ukubaluleka E. Lesi sibalo kuyoba ulingana kabili ubukhulu, isb 12 mm.

Ucabange ukuthi ubude mkhiqizo 10 m. Ukuze ubale inani emphethweni, ubude ehlukaniswa isinyathelo 866 futhi ukuthola izinto. Okulandelayo, nqumani indlela ubude tube lukathayela usesimweni sisalokhu. Nge ububanzi, isib, 52 mm, endaweni ingqikithi ukwakhiwa 54,92 sq. m.

Ukukhethwa upende

Inqawe esetshenziselwa yokudweba izinhlobo ezahlukene upende:

• koqweqwe lwawo Acrylic abakhona lichaza ekwakheni ezihogelwayo, ukuhlinzeka isicwebezelisi sekugcineni eqinile futhi iqine.
• koqweqwe lwawo Alkyd ethulwa ukudayiswa in ezahlukene enkulu imibala. uyinki onjalo nazo libhekene ukuqina, yakha isendlalelo okuthembekile akusho crack fade.
• Amanzi-dispersive upende. Izinzuzo izingoma ezinjalo zihlanganisa ikhono lokuthi omiswe okusheshayo futhi ukungabi khona malodor. Okumbi - ukumelana kahle nokuhuzuka namanzi. Ngaphambi kokusebenzisa i-uyinki of ukuhlakazwa amanzi-based ipayipi kufanele camera Priming ejenti.
• Amafutha upende. Ukuze imidwebo amapayipi kuyaqabukela asetshenziswa. Itholakala umbala uhla encane. Ngaphambi yokudweba metal evele, kuhlanganise amapayipi, kudingeka isicelo primer, okunganikeza obuqinile upende. Umbala Ukwakheka ngesisekelo amafutha isetshenziswa primer omisiwe izingqimba okungenani ezimbili.

Lapho ukhetha uhlobo upende ukuze imibala ipayipi kuyadingeka, okokuqala kunakho konke, ukugxila inhloso yokusebenza izimo zabo, njengoba izinto ezifana lokushisa, umswakama, ingozi mechanical, njll, kuzoya kanjani ukuthi ukuhlala phakade upende, futhi isikhathi inkonzo amapayipi ngokwabo.
