Umbhobho wokukhusela intambo yamandla ye-MPP, umbhobho we-MPP

1. Umbhobho wamandla we-MPP une-insulation yombane egqwesileyo.

2. Umbhobho wamandla we-MPP unobushushu obuphezulu bokuguquguquka kobushushu kunye nokusebenza okuphantsi kwempembelelo yobushushu.

3. Iimpawu zokuxinana kunye nokucinezela zombhobho wamandla we-MPP ziphezulu kune-HDPE.

4. Umbhobho wamandla we-MPP ulula, uthambile, unamandla amancinci okungqubana kwaye unokudityaniswa ngokuxubana kobushushu.

5, ukusebenza kakuhle kokusingqongileyo, akukho ungcoliseko lwezinto, ubomi benkonzo ende.

1. Ilula, yenza kube lula ukuyithutha nokuyifakela; inokuguquguquka okuhle, okwenza kube lula kwaye kungabizi kakhulu ukuyibeka. Iyakwazi ukuphinda isetyenziswe, ihlangabezana nemigangatho yokusingqongileyo; xa imibhobho igoba, uxinzelelo kwicandelo eligobileyo lunokupheliswa ngokukhawuleza, kuthintelwe isiganeko 'sokubuyela umva', esenza kube lula ukusebenza kolwakhiwo kwaye kuthintelwe ukonakala kwiindawo ezigobileyo zemibhobho ngenxa yoxinzelelo ngexesha lokusetyenziswa;

2. Ukulahleka okuncinci kokungqubana kumbhobho, amandla okuhambisa ulwelo lombhobho mkhulu nge-10% kunowombhobho we-PE-X onobubanzi obufanayo; ukusebenza kokuchasana nempembelelo yimbhobho ye-PE-X. Iphindwe kabini;

3. Ubushushu bokwaphuka buphantsi, kwaye umbhobho usebenza kakuhle kakhulu kubushushu obuphantsi. Ubuncinane berediyasi yawo yokugoba buphindwe kahlanu kunobubanzi bangaphandle bombhobho;

4. Ukumelana kakuhle nokugqwala kweekhemikhali, akukho mhlwa, ubomi obude benkonzo.

5. Ukumelana okuhle kokuqhekeka, ukumelana kokuqhekeka kuhlala ixesha elide emva kokuveliswa kunye nokwenziwa;

6. Akukho zongezo zinobuthi ezongezwayo kwinkqubo yokuvelisa izinto zombhobho, udonga lwangaphakathi olugudileyo, akukho kukhula kwebhaktiriya, zingasetyenziswa ngokukhuselekileyo ekudluliseni amanzi okusela nakwezinye iindawo;

7. Ukusebenza kakuhle kokusasaza ubushushu, ukuqhuba ubushushu kwe-0.4W/(m • K), kunokonga amandla amaninzi kwizicelo zokufudumeza, ngoko ke ukusetyenziswa kwe-PE-RT kwindawo yokufudumeza kunokunika ukusebenza okupheleleyo kwiimpawu zayo ezibalaseleyo;

8. Ukudityaniswa

Njengezinto ezibalulekileyo kulwakhiwo lobunjineli bamandla, imibhobho yamandla ye-MPP ibalulekile ekuqinisekiseni ukusebenza ngokukhuselekileyo kwemigca yekhebula. I-Polypropylene yaziwa ngamandla ayo aphezulu, ukuqina kwayo, kunye nokumelana nobushushu okugqwesileyo, ukumelana nokugqwala, kunye neempawu zokuthintela ubushushu zombane. I-polypropylene eguquliweyo iphucula ngakumbi ezi mpawu zibalulekileyo.

Umbhobho wamandla we-MPP ube yinto ebalulekileyo ebaluleke kakhulu kulwakhiwo lobunjineli bamandla ngenxa yeempawu zayo ezintle zezinto kunye neendawo ezibanzi zokusetyenziswa.

Isishwankathelo seenkcukacha kunye neemodeli zombhobho wokukhusela intambo yamandla ye-MPP

Iinkcukacha zayo kunye neemodeli zahlulwe kakhulu ngokwee-diameter zangaphandle, ubukhulu bodonga kunye nobude. Oku kulandelayo luhlelo oluneenkcukacha lweenkcazo ezifanayo:

1. Ukudibanisa ububanzi bangaphandle kunye nobukhulu bodonga

DN90mm
Ubukhulu bodonga: 5mm, 6mm

DN110mm
Ubukhulu bodonga: 6mm, 7mm, 8mm, 9mm, 10mm

DN160mm
Ubukhulu bodonga: 7mm, 8mm, 9mm, 10mm, 11mm, 12mm

DN180mm
Ubukhulu bodonga: 10mm, 12mm, 15mm

DN200mm
Ubukhulu bodonga: 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm

DN250mm
Ubukhulu bodonga: 13mm, 14mm, 15mm, 16mm, 17mm, 20mm

2. Iinkcukacha zobude

Ubude bombhobho omnye obuqhelekileyo ziimitha ezi-6, iimitha ezi-9, iimitha ezili-12.

3. Iimeko zokwahlulahlula kunye nokusetyenziswa

Uhlobo lokumba: lufanelekile kwiiprojekthi zokubeka iintambo zesiqhelo.

Uhlobo olungeyombiwa (ipayipi yokugquma/yokutsala): isetyenziselwa ukhuseleko lweentambo kwiindawo ezikhethekileyo ezifana neendlela, oololiwe kunye nonxweme lomlambo ngaphandle komonakalo omkhulu emhlabeni.

Iingcebiso zokukhetha:

Ububanzi obuncinci (obufana ne-DN90mm, DN110mm) busetyenziswa kakhulu ekubekeni iintambo ngokubanzi, ubukhulu bodonga buncinci kakhulu;

Ububanzi obukhulu (obufana ne-DN200mm nangaphezulu) bufanelekile kwiintambo ze-voltage eziphezulu kakhulu okanye kwiindawo ezintsonkothileyo (ezifana nokuwela iindlela), kwaye ubukhulu bodonga obukhulu kufuneka bukhethwe ukuze kuphuculwe amandla okuthwala uxinzelelo.

4. Imo yoqhagamshelo

Indlela yoqhagamshelo lombhobho wokukhusela intambo ye-MPP ikwayinxalenye yeenkcukacha zayo. Iindlela zoqhagamshelo eziqhelekileyo ziquka uqhagamshelo lwesokethi, uqhagamshelo lwe-hot fusion, uqhagamshelo lwe-electrical fusion, njl. Iindlela zoqhagamshelo ezahlukeneyo zifanelekile kwiimeko ezahlukeneyo zokusetyenziswa kunye neemfuno zobunjineli, kwaye indlela yoqhagamshelo efanelekileyo inokuqinisekisa ukhuseleko kunye nokuthembeka kombhobho wentambo.

Xa ukhetha imibhobho yokukhusela intambo ye-MPP, kubalulekile ukuqwalasela iimfuno ezithile zeprojekthi, iimeko zokwakha, kunye neenkcukacha kunye neempawu zeentambo, ukuqinisekisa ukuba zonke iinkcukacha ziyahambelana. Ukongeza, ukuqinisekisa umgangatho kunye nokhuseleko lweentambo, kubalulekile ukukhetha abavelisi abaziwayo kunye neemveliso ezikumgangatho ophezulu. Ngexesha lenkqubo yokwakha, kuyimfuneko ukulandela imigangatho yokwakha efanelekileyo kunye neemfuno zobugcisa ukuqinisekisa umgangatho wokufakelwa kunye nokusebenza kakuhle kweentambo.

Ngamafutshane, umbhobho wokukhusela intambo ye-MPP uneendlela ezahlukeneyo, kwaye ukukhethwa kweendlela ezifanelekileyo kunye nendlela yokunxibelelana kubaluleke kakhulu ekukhuseleni intambo. Kwindlela yokusebenza, kuyimfuneko ukuqwalasela nokukhetha ngokupheleleyo ngokwemeko ethile, ukuqinisekisa ukhuseleko, ukuthembeka, ukonga kunye nokusebenza kakuhle kombhobho wentambo.
