Ubukhulu bamapayipi epulasitiki ngokuthuthwa kwamanzi. Amapayipi epulasitiki okuthuthwa kwamanzi: amazinga

Amapayipula epulasitiki okugcoba, izinhlobo, ubukhulu bawo oboniswe ngezansi, usanda kuba ethandwa kakhulu. Zenziwe nge-polypropylene, i-polyvinylchloride, i-polybutylene, ne-polyethylene. Imikhiqizo enjalo iyadingeka ekuhlelweni kwezinhlelo zokuthuthwa kwamanzi, ezibonakala ngokumelene nomthelela wezinto ezilimazayo. Ungabeka amapayipi ezindlini zomkhaya noma zezimboni. Imikhiqizo yekhwalithi inebushelelezi obuhle, okuqeda ithuba lokugqoka. Ekufakweni kuyadingeka ukusebenzisa i-hacksaw yendabuko, okuhloswe ngensimbi, amazinyo ayo angeke awenze i-burrs.

Incazelo yamapayipi okugeleza amapulasitiki

Amapayipi epulasitiki okusetshenziselwa ukuthuthwa kwamanzi, ubukhulu, izindinganiso zazo ezizochazwa ngezansi, zenziwe ngama-polym compounds. Ubuchwepheshe buqinisekisa ukuqina, ukwethenjelwa nokuqina kwesistimu yokuthuthwa kwamanzi. Ungasebenzisa ukwaziswa ngaphakathi nangaphandle kwendlu. I-throughput ihlala ingapheli, ngisho noma ipayipi igoba nge-angle edingekayo. Ngokwenza uhlelo lwezokuthuthwa kwamanzi, ungabheka izindleko ezifanele, ukuqina, kanye nokuntuleka kwesidingo sokuvikelwa kwe-cathodic. Ngakho-ke, emva kokufeza umsebenzi akukho sidingo sokugcinwa njalo. Amapayipi abhekene nokuqhutshwa okuphansi kwe-thermal, okuvimbela ukushisa amanzi amanzi. Isisindo semikhiqizo sibavumela ukuba bahanjiswe ngaphandle kokusetshenziswa kwemishini ekhethekile, futhi ukuvikeleka okuthembekile kuqeda ukusakazeka kwamagciwane nama-bacterium.

Ubukhulu

Amapayipi okugeleza kwamaplastiki, izinzuzo zawo ezichazwe ngenhla, angaba nobukhulu obuhlukahlukene, ngayinye ehlinzekwa ngezinga elihlukile lokulayisha. Uma kunesidingo sendlela yokuhlanzeka kwesakhiwo sefulethi noma into yenhlalakahle, khona-ke ukuphakama okumangalisayo kufanele kusetshenziswe. Ngakho-ke, isibalo esingenhla samamitha angu-200 sifanele izibhedlela, amahhotela noma ama-saunas. Ukulinganisa okumangalisayo, okulingana namamitha ayizigidi ezingu-300, kusetshenziselwa ukusebenza kwezikhungo zezimboni. Izinhlobo nezilinganiso zamapayipi epulasitiki wokuthuthwa kwamanzi kumele kukhethwe ngaphambi kwesikhathi sokuqala komsebenzi. Ngamapayipi wokwakha ahlukene amamitha amancane kakhulu asetshenzisiwe. Ngakho-ke, uma usebenzisa amamitha angu-150 uma ufaka i-riser, ngeke isetshenziswe ngokugcwele, okuyiqiniso ukuthi indlu enenani eliphezulu lamagumbi okugeza ahlukaniswe amane.

Amazinga okuhambisa amapayipi epulasitiki

Ngokuhambisana nomenclature, amapayipi okuhambisa amanzi asetshenziselwa amapulasitiki ayenziwe, ububanzi bawo obungama-millimitha angu-50-110. Ubuningi buhluka kusuka ku-3 ukuya ku-3, kumamitha amabili. Ukuze kwenziwe ilungiselelo lokuthuthwa kwamanzi wangaphandle , kufanele kusetshenziswe izinhlobo eziyisibili, okukwazi ukuhlinzeka ngamandla kagesi adingekayo. Uma udinga amapayipi eplastiki we-plumbing, indlela yokukhetha ubukhulu kubalulekile ukwazi ngisho nangaphambi kokuthenga. Noma kunjalo, kubalulekile ukunquma ukuthi hlobo luni lwemikhiqizo oluzodingeka. Isibonelo, amajoyina angaphandle, kufaka phakathi amalunga wezimboni, adinga ukusetshenziswa kwamapayipi okonakele okwenziwa nge-polyethylene enezintambo ezimbili. Phakathi kwezinzuzo eziyinhloko kulokhu kungase kube ukuhlukaniswa kwamakhemikhali okuvelele, ukuqina okunamandla kwendandatho, okuvumela ukubeka endaweni ejulile yamamitha angu-20. Ukuze kusetshenziswe izinhlelo zokucindezela, kusetshenziselwa amapayipi e-polyethylene e-sewer, aphethe izindawo ezifanele. Ububanzi buhlukahluka kusuka kumamitha angu-10 ukuya ku-1200.

Ukusetshenziswa kwe-HDPE

Ukulinganisa kwamapayipi epulasitiki wokuthuthwa kwamanzi okukhulunywe ngawo ngenhla kukhulunywe ngenhla, kodwa kubalulekile ukucacisa futhi ukuhlukahluka komkhiqizo. Phakathi kwamanye, kufanele kuqashelwe i -polyethylene ephansi kakhulu, ebonakala ngamandla amakhulu. Iphumelela ngokumelene nomthelela wendawo enonya.

I-GOST 22689.2-89

Kubalulekile ukukhetha kahle ubukhulu bemipayipi yepulasitiki yokuthuthwa kwamanzi, kanye nokunquma ezihlukahlukene. Imikhiqizo ekhonjisiwe ngenhla ayilawulwa amazinga wombuso futhi ingahle yenziwe ngaphansi kwemibandela evumelanisiwe nekhasimende. Ngokuqondene namapayipi e-polyethylene okwenzelwe ukuxhumana kwangaphakathi, i-GOST, okukhulunywe ngenhla, isetshenziselwa ukwenziwa. Ithi ipayipi ingaba nosayizi phakathi kwamamitha amabili no-8. Imingcele elandelayo yizilinganiso eziphakathi: 3; 5.5; 6. Ngomsebenzi wangaphakathi, ububanzi bombhobho onjalo kungaba ngamamithamitha angama-40 kuya kwangu-110. Amanani aphakathi angama-50 namaphesenti angama-90.

Ukuthintelwa kokusetshenziswa

Kubalulekile ukuthi ukhethe kahle ukulinganisa kwamapayipi epulasitiki ngokuthuthwa kwamanzi, kodwa kufanele ucabangele nokulinganiselwa kokusetshenziswa. I-standard isebenzisa ukusetshenziswa kwamapayipi ekuxazululeni amandla adonsela phansi ohlelweni lokuthuthwa kwamanzi. Ngokuqondene nezinhlelo zokucindezela, zihambisana nezinye izincwadi ezilawulayo. Naphezu kwezinga, ipayipi le-polyethylene, elinesibonakaliso senjoloba, ingaba yingxenye yesistimu ngokusebenzisa amaphampu okuhambisa amanzi. Uma ingcindezi inganaki, lolu xhumano luyoba luningi ngokwanele. Izinhlobo nezinayizi zamapayipi epulasitiki okuthuthwa kwamanzi okugeleza komhlaba kuzokuvumela ukuba uhlomise uhlelo ngendlela efanele, kodwa kubalulekile ukucabangela amanye amaphuzu okumele agcinwe ngesikhathi sokusebenza. Ngakho, imikhiqizo yenzelwe ukushisa okungadluli ama-45 degrees. Kodwa-ke, ukukhuphuka kwesikhashana kuvunyelwe, okungafinyelela ezingeni lika-60.

Lesi sidingo sinconywa ukuba sithathwe ngobukhulu obuningi, ngaphandle kokusetshenziswa kwesistimu yokukhishwa kwamanzi, okushisa okuphezulu.

Izincomo

Amapayipi epulasitiki okuthuthwa kwezidakamizwa, ubukhulu bawo obungafani kakhulu, asetshenziselwa izinhlelo zokubeka kokubili emzini nasemaphandleni. Amapayipi anjalo asetshenziselwa ngokuphindaphindiwe ngenxa yokuthi ayengenawo ukunyakaza kwenhlabathi futhi ahlonishwa ngodokotela futhi aguquguquke. Amapayipi epulasitiki okuthuthwa kwamanzi, ubukhulu okumele uwathathe ngisho nangaphambi kokuqala komsebenzi, awunamandla okwenza ugesi, abe nokumelene okuhle kokushisa futhi abesabi ukwehliswa kwemidiya evuthayo. Awukwazi ukwesaba ukuthi umswakama kanye namanzi angakwazi ukuphazamisa izici zokusebenza zendaba. Phakathi kwezinye izinto, indawo ayiyona indawo evumayo yokuvela nokukhiqizwa kwama-bacterium.

Izici ezengeziwe

Ukusebenzisa imikhiqizo echazwe, ungathembela ekusebenzeni isikhathi eside kwesevisi, okuqinisekisiwe iminyaka engu-50. Uma ukufakwa kwenziwa ngendlela efanele, futhi ukuhlinzwa kwenziwa ngokuvumelana nemithetho, ngaleyo sikhathi kungase kwande. Amakhasimende akhetha idatha yomkhiqizo futhi ngesizathu sokuthi bayakwazi ukuthatha umsindo, okuyinto enhle ngaphezu kwamaphayipula epulasitiki.

Isiphetho

Uma phakathi nomsebenzi usebenzisa amapayipi okonakalisiwe, ke ngokujoyina kwabo sisebenzisa ama-sliding couplings. Bakhethwa uma bebeka uhlelo emhlabathini ngaphandle kwendawo. Ekulungisweni kwamanethiwekhi wangaphakathi, lapho kuwumkhuba wokusebenzisa amapayipi amacilongo, ukuqhutshwa kwemishini kufanele kwenziwe ngokusebenzisa ubuchwepheshe obufanayo obusetshenziselwa noma iyiphi enye ipayipi yeplastiki ehlonyelwe ukufaka uphawu lwezindandatho zenjoloba. Uma wenza umsebenzi njengenye yezimo ezibaluleke kakhulu, kubalulekile ukusebenzisa izakhi eziphezulu.
