Amapayipi e-HDPE Akha Uhlelo Olusebenzayo Lokonga Amanzi

Njengoba ukuntuleka kwamanzi emhlabeni kukhula, Izinhlelo zokuchelela ezisebenza kahle zokonga amanzi seziyisidingo esibalulekile kwezolimo, ukulungiswa kwezwe, nobunjiniyela bakamasipala. Njengomkhiqizi we HDPE amapayipi nge 20 iminyaka yesipiliyoni sembonini, sifingqe umthetho wegolide womklamo wesistimu ogxile kumapayipi e-HDPE ngokusekelwe kudatha esebenzayo evela ngaphezulu 300 amaphrojekthi okunisela okonga amanzi. Lesi sihloko sizoveza indlela yokwandisa ukuchelela ngokusebenza kahle nge 30% kanye nokunciphisa ingozi yokuvuza 50% ngesakhiwo senethiwekhi yamapayipi esayensi.

Kungani amapayipi e-HDPE e- umnyombo wezinhlelo zokuchelela ezonga amanzi?

1. Ukuqhathaniswa kwedatha elinganisiwe: Amapayipi we-HDPE vs. Amapayipi endabuko

Ukuqhathaniswa kwesilinganiso sokuvuza: Izinga lokuvuza kwepayipi lensimbi > 12% ngonyaka, Isilinganiso sokuvuza okuhlangene kwepayipi le-PVC 8%, I-HDPE hot melt welding ifinyelela ukuvuza okungu-zero (Isikhungo Sikazwelonke Socwaningo Lwezinsiza Zamanzi 2023 idatha)

Impilo yesevisi: Amapayipi e-PVC ajwayelekile anesikhathi sokuphila 8-10 iminyaka, kuyilapho amapayipi e-HDPE enobude bokuphila obufika ku 50 iminyaka endaweni ye -60 °C kuye 60 °C

Izinga lokugcinwa kokugeleza: Ipayipi le-DN200 linezinga lokulahlekelwa kwengcindezi kuphela 3.2% phezu 20 iminyaka (idatha eqinisekisiwe yi-TUV yaseJalimane)

2. Core advantages of HDPE pipes

Molecular-level sealing: Hot-melt welding forms molecular chain fusion, completely eliminating the risk of leakage at the interface

Dynamic pressure resistance: CRA pressure curves show that HDPE pipes can withstand 2.5 times instantaneous water hammer impacts

Terrain adaptability: 1500D bending radius enables seamless installation in complex terrains

Ecological safety: FDA food grade certified, heavy metal leaching < 0.001ppm

Ezinhlanu important rules for designing Water-saving irrigation systems

Rule 1: Three-level pressure zoning control

High-pressure zone (> 0.6I-MPa) : The main pipe is made of SDR11 series HDPE pipe with a wall thickness of ≥12.3mm

Medium pressure zone (0.4-0.6I-MPa) : Branch pipes of SDR13.6 specification, equipped with pressure-compensating drippers

Low-pressure area (< 0.4I-MPa) : Inethiwekhi ye-capillary isebenzisa i-labyrinth drip irrigation tape enengcindezi yokusebenza engu-0.1MPa

Rule 2: Imodeli yokubala ye-hydraulic enembile

Bala ukulahlekelwa ikhanda endleleni usebenzisa ifomula ye-Hazen-Williams:

  \ [h_f = 10.67 \ \ izikhathi izikhathi L Q ^ {} 1.852 / (C ^ ^ 1.852} {\ izikhathi D 4.8655} {) \)

  (Inani C lithi 150, Ubulukhuni bepayipi le-HDPE 0.007mm)

Rule 3: Ukucushwa kwepharamitha yokunisela okuhlakaniphile

Uhlobo lokunqampuna	Amandla okunisela (mm/h)	Isidingo samanzi ngosuku (m³/mu)	I-diameter yepayipi ephakanyisiwe
Imifino ye-greenhouse	6-8	2.5-3.2	I-DN50
Izihlahla zezithelo	4-6	1.8-2.4	DN65
Utshani	10-12	3.5-4.2	I-DN40

Amathiphu Awusizo Okwakheka Kwepayipi Le-HDPE (ngokuhlaziywa komdwebo wesakhiwo se-3D)

Ithiphu 1: I-algorithm ye-Terrain adaptive topology

Sebenzisa “ukuvinjelwa komugqa wekhonta” yokwakheka kwamapayipi emithambekeni, futhi ufake ama-valve okusiza ukucindezela lapho umthambeka umkhulu kuno-15°

A “feng” inethiwekhi yamapayipi anomumo isetshenziswa endaweni eyisicaba, ngezikhala zamapayipi egatsha ngokwesilinganiso 1.2:1 ebangeni lama-nozzles

Ithiphu 2: Amaphuzu abalulekile okulawula ikhwalithi ye-hot melt welding

210±5 ° C izinga lokushisa lokuhlanganisa ligcina ingcindezi engu-0.15MPa

Isikhathi sokumunca ukushisa = Ukujiya kodonga lwamapayipi (mm)× imizuzwana engu-10, isikhathi sokupholisa ≥ ukujiya kodonga (mm)×1 iminithi

Ithiphu 3: Idizayini yesinxephezelo sokunwetshwa kwe-Dynamic

Setha izinxephezelo ze-Ω njalo 50 amamitha, nge 5% isibonelelo sesandiso

Ama-pier angaguquki afakwe kukhonkolo ye-C25, ngezilinganiso = 3 izikhathi ububanzi bepayipi

Icala elingokoqobo: 

Iphrojekthi yensimu kakotini engu-3,000-mu eXinjiang yazuza a 43% ukonga amanzi kanye a 22% ukwanda kwesivuno ngemu ngayinye ngokusebenzisa amapayipi e-SDR17 ochungechunge lwe-HDPE kanye namateyipu okunisela okuconsisa anxephezela ukucindezela. Isakhiwo senethiwekhi yamapayipi samukele i- “amazinga amathathu kanye nezindawo ezine” imodeli, namapayipi amakhulu abekwe eduze kwama-ridge ensimu kanye namapayipi amagatsha ahlukanisiwe 56 amamitha, okuhambisana nobubanzi bokufafaza be 47 amamitha.

Finhlanganisela yethu emisha yesistimu yokunisela ehlakaniphile

1. Ukuhlanganiswa kwezinhlelo zokuqapha ze-inthanethi Yezinto

Faka izinzwa zokuswakama komhlabathi njalo 200 amamitha

Ivalvu kagesi ixhunywe ohlelweni lwe-SCADA ngephutha elingaphansi kuka-0.02MPa

2. Isixazululo sezobuchwepheshe sokulwa nokuvala

Faka isihlungi se-laminated ye-120-mesh ekhanda

Ipayipi elikhulu lakhiwe nge 0.5% i-slope kanye ne-valve yokudonsa njalo 100 amamitha

3. Ukulungiswa kweziteshi zokumpompa ilanga

5I-kW photovoltaic system ishayela iphampu ye-booster yamapayipi

Ngebhethri yokugcina amandla amahora angama-24 ukuzinza kwengcindezi

Umhlahlandlela wokukhetha ipayipi le-HDPE elinewaranti yeminyaka engama-20

Ithebula eliyisithenjwa elisheshayo lamapharamitha wokukhetha

Izinto	Amanani ajwayelekile	Indlela yokuthola
Isilinganiso sokugeleza kwe-Melt	0.2 0.4 g / 10 imiz	I-GB/T3682
Izinga lokuhoxiswa kwe-longitudinal	≤3%	I-GB/T6671
Isikhathi sokungeniswa kwe-oxidation	≥20min	I-GB/T19466.6

Isikhumbuzi esikhethekile: Qiniseka ukuthi uyakubona ukumakwa kwebhendi eluhlaza okwesibhakabhaka. Ukuminyana kwezinto zokusetshenziswa zebanga le-PE100 kufanele kube ≥0.948g/cm³ ukuze kuqinisekiswe ukuthobelana ne-GB/T13663 ejwayelekile kazwelonke..
