Ngexesha lokwakha nokuphuculwa kweNdlu, imibhobho ayisoloko isetyenziselwa ukuthutha ulwelo okanye iigesi. Rhoqo basebenza njengezinto zokwakha - ukwenza isakhelo sezakhiwo ezahlukeneyo, ukuxhasa amakhonkco, njl. Xa kumiselwa iiparamitha zeenkqubo kunye nezakhiwo, kuyimfuneko ukubala iimpawu ezahlukeneyo zezinto zayo. Kule meko, inkqubo ngokwayo ibiza ukubalwa kombhobho, kwaye kubandakanya imilinganiselo kunye nokubala.
Ufuna ukubala iiparameter zeparamitha
Kulwakhiwo lwale mihla, hayi kuphela intsimbi okanye imibhobho ye-gavated isetyenzisiwe. Ukhetho sele lubanzi kangako - i-PVC, i-Polythylene (PND kunye ne-PVD), iPolypropylene, i-Folyplaene, i-FerainPlestic, i-corupeds. Zilungile ngaphakathi koko azinangxaki enkulu njenge-analog. Nangona kunjalo, xa uhambisa iimveliso ze-polymeric kwimitha enkulu yokwazi ubunzima babo kukukhetha - ukuqonda ukuba loluphi uhlobo lwemoto olufunekayo. Ubunzima bombhobho wensimbi bubaluleke ngakumbi - ukuhanjiswa kuqwalaselwe kwi-tonnage. Ke le paratho ilawulwa ngokukhethekileyo.
Yintoni engenakulinganiswa ukuba ibalwe
Yazi indawo yomgangatho wangaphandle wombhobho, iyimfuneko ekuthengweni kweepeyinti kunye nezixhobo zokuthambisa. Iimveliso zensimbi kuphela ezipeyintiweyo, kuba ziphantsi kosulelo ngokuchaseneyo nePolymer. Ke kuya kufuneka ukhusele umphezulu kwiziphumo zemithombo yeendaba. Bazisebenzisa rhoqo ukuze kwakhiwe iingcingo, imigaqo-nkqubo yokugcina indlu (igaraji, ii-barn, ukweza, ukhuseleko luyimfuneko, kuba zonke iiflene zifuna ukufaka imibala. Apha kuya kuba yimfuneko kwindawo yendawo yokupeyinta - indawo yangaphandle yombhobho.
Xa uphuma inkqubo yokubonelela ngamanzi kwindlu yabucala okanye i-cottage, imibhobho ifakwe kumthombo wamanzi (kakuhle okanye iqula) kwiNdlu - phantsi komhlaba. Konke okufanayo, ukuze bangabeki ntwatsha, kuyafuneka. Bala inani lokufakwa lunokuba yindawo yomthwalo womphezulu wangaphandle wombhobho. Kuyo le meko kuyimfuneko ukuthatha umbandela oqinileyo-udibaniselwano kufuneka lube ngaphezulu kwendawo eqinileyo.

Icandelo lomnqamlezo liyimfuneko ukufumanisa ukupapashwa - nokuba le mveliso iya kuba nakho ukwenza inani elifunekayo lolwelo okanye igesi. Iparameter efanayo ihlala ifuneka xa ukhetha ububanzi bombhobho wokufudumeza kunye nepayiphu yamanzi, ukubala intsebenzo yempompo, njl.
Ububanzi bayo bangaphandle, ubukhulu becala, i-radius
Imibhobho yimveliso ethile. Bane-diameter yangaphakathi nangaphandle, njengoko benayo, ubukhulu bayo buxhomekeke kuhlobo lombhobho kunye nezinto ezenziwayo. Kwiimpawu zobuchwephesha, ububanzi bangaphandle kunye nobunzima bodonga babonisa rhoqo.
I-Inner kunye ne-Outter yombhobho, ubukhulu becala
Ukuba nale milinganiselo mibini, kulula ukubala ububanzi be-Inter-ukusuka ngaphandle ukuba bathathe ubuncwane obubini: d = d - 2 * s. Ukuba unayo i-sangqa kumphandle-32 mm, Ebubanzini bodonga yi-3 mm, ngoko ke ubukhulu ngaphakathi iya kuba: 32 mm - 2 * 3 mm = 26 mm.
Ukuba, phezu koko, kukho yangaphakathi ubukhulu kunye nodonga balo babulingana nesandla, kufuneka ongaphandle - ukuya ixabiso ekhoyo, yongeza watshisa izitha kabini ubukhulu ezijijekileyo.
Nge-radius (eboniswe ngunobumba r) kulula- sisiqingatha sedayamere: R = 1/2 D. Umzekelo, siya kufumana i-radius yombhobho enobubanzi obuyi-32 mm. Yahlula-nye ezingama-32, sifumana i-16 mm.
Ukulinganisa i-calipers ichaneke ngakumbi
Kuthekani ukuba idatha yobugcisa Akukho imibhobho? Ukulinganisa. Ukuba ithe kwakufuneka ukuchaneka ethile, umgca njengesiqhelo ilungele, kuba imilinganiselo echanileyo ngakumbi kubhetele ukusebenzisa i imbi.
Ukubalwa komphezulu wombhobho
Umbhobho sisilinda esinde kakhulu, kwaye indawo yomphezulu wombhobho ibaliwe njengendawo yesilinda. Kuba izibalo, embindini kuya kufuneka (abangaphakathi nabangaphandle - kuxhomekeke apho buvela ufuna ukubala) kunye nobude kwicandelo oyifunayo.
Ifomula yokubala indawo esecaleni yombhobho
Ukufumana indawo esecaleni yesilinda, jika irediyo kunye nobude, ixabiso leziphumo liphindaphindwe kabini, kwaye ke ngenani "pi", sifumana ixabiso elifunayo. Ukuba unqwenela, ungabala umphezulu wemitha enye, ke inokuphinda iphindwe ngobude obufunayo.
Inqaku lesihloko: amakhethini asebenzayo kwigumbi lokuhlambela
Umzekelo, sibala umphezulu weqhekeza lombhobho wobude obuziimitha ezi-5, kunye nobubanzi be-12 cm. Isiqalo se-12 cm. Isiqalo se-2, sifumana i-6 cm. Ngoku yonke i Amaxabiso kufuneka aziswe kwiiyunithi enye yemilinganiselo. Ekubeni lo mmandla kuqwalaselwa kwi square metres, ngoko ke cm ziguqulelwa leemitha. I-6 cm = i-0.06 m. Ukuqhubeka sibambe endaweni yefomula: S = 3,14 * 0.06 * 5 = 1.884 M2. Ukuba ajikelezayo, kuya 1.9 m2.
Ukubala ubunzima
Ngokubala ngobunzima bombhobho, yonke into ilula: Kufuneka uyazi ukuba ingakanani imitha yamanqanaba endlela ezinobunzima bendlela, emva koko ndiphindaphinda olu bukhulu kubude beemitha. Ubunzima Imibhobho ephakathi yentsimbi ngeenxa na iincwadi reference, ekubeni olu hlobo wentsimbi mgangathweni. Ubunzima bemithi enye yerose ixhomekeke kububanzi kunye nobungqingqwa bodonga. Enye mzuzu: ubunzima umgangatho ziyanikezelwa mninzi nawo 7,85 g / cm2 kuyinto ukuvela kucetyiswa yi GOST.

KwiTheyibhile D - Ububanzi bangaphandle, indinyana enemiqathango yinto engaphakathi, kunye nenye ingongoma ebalulekileyo: Ubunzima beemveliso eziqengqelekayo zensimbi zibonisiwe, zidityaniswe nge-3%.

INDLELA YOKUXELISA INDAWO YOKUGQIBELA
Ifomula yokufumana icandelo le-tube yomnquba
Ukuba umbhobho ngumjikelo, indawo enqamlezileyo yecandelo kufuneka ithathelwe ingqalelo ngokwefom yendawo yesangqa: S = π * R2. Apho irediyo (ngaphakathi), π - 3.14. Iyonke, kuyimfuneko ukwakha i-radius kwisikwere kwaye iphindaphindwe ngo-3.14.
Umzekelo, icandelo lomphunga lombhobho kunye nobubanzi be-90 mm. Sifumana iradiyo - i-90 mm / 2 = i-45 mm. Kwiisentimitha eziyi-4,5 cm. Siye sakhiwa kwisikwere: 4.5 * 4.5 = 2.025 cm2, sibambe endaweni yefomula s = 2 * 40.5 cm2.
Indawo yombhobho wecandelo le-pirping ithathelwa ingqalelo yifomula yendawo ende: S = A * B, apho i-A kunye ne-B-ubude becala loxande. Ukuba ubala icandelo leprofayile ye-40 xm, sifumana s = 40 mm * 50 mm = 2000 mm2 okanye i-20 cm2 okanye i-4002 m2 okanye i-4002 m2 okanye i-4002 m2.

INDLELA YOKUXELISA INDLELA YOKUZIPHATHA KWAMANZI KWI-PAIPLEW
Xa ulungiselela inkqubo yokufudumeza, ufuna iparamitha enjalo njengevolumu yamanzi aya kulunga kumbhobho. Oku kuyimfuneko xa kubalwa inani lokuphola kwinkqubo. Kule meko, kufuneka ifomyuli yevolumu yesilinda iyafuneka.
Ifomula yokubala ivolumu yamanzi kumbhobho
Zimbini iindlela: Okokuqala zibala indawo enqamlezileyo (echazwe apha ngasentla) kwaye iphindaphindwe kubude bombhobho. Ukuba uqwalasela yonke into ngokwefomula, ufuna iradius yangaphakathi kunye nobude becala. Bala ukuba kungakanani amanzi abekwe kwinkqubo yemibhobho engama-32 yeemilimitha kunye nobude obuziimitha ezingama-30.
Okokuqala, siza kudlulisela kwiimitha: 32 mm = 0.032 m, sifumana irediyo (i-0,016 m. I-0,0241 m = 0,024 m = 0,0241 m = 0,0241 m = 0,0241 m = 0,024 m = 0,024 m = Ijika = ngaphezulu kwamakhulu amabini emide ye-cubic. Kodwa siqhele ivolumu yenkqubo yokulinganisa iilitha. Kwiimitha ze-cuic zeikubhite ukuba batshintshele kwiilitha, kufuneka uphindaphinde idijithali ekhokelela kwi-1000. Ijika i-24.1 iilitha.
