Impompo ehlala iphantsi kwamanziiintambo zigcina iimpompo zisebenza kwaye iiprojekthi zikwishedyuli - ngakumbi kumaqula, ukunkcenkceshela, amanzi amdaka kunye neenkqubo ezikude nonxweme apho ukungaphumeleli kuthetha ukuchithwa kweendleko. Esi sithuba siphendula imibuzo yokuthengwa kwempahla kunye namaqela obunjineli abuza kakhulu, ichaza iimpawu zokuqina ezibonelelwa ngababoneleli abaphezulu, kwaye inika uluhlu lokuthenga olusebenzayo ukuze uthenge intambo efanelekileyo okokuqala.
Yintoni eyenza intambo ibe ngaphantsi kwamanzi - yeyiphi imathiriyeli kunye nolwakhiwo olubaluleke kakhulu?
Intambo yokwenyani entywilayo emanzini -yokugquma ibakala kunye nesingxobo sangaphandle esomeleleyo (ukhetho oluxhaphakileyo: XLPE, EPR, okanye iPVC eyenziwe ngokukhethekileyo), ehlala idityaniswa neneoprene okanye ibhatyi yePE yangaphandle yokuxhathisa imichiza kunye nokuqhawuka. Ufakelo olumagingxigingxi, ababoneleli bongeza izixhobo zentsimbi (ucingo lwentsimbi okanye iteyiphu) ukukhusela kumonakalo womatshini kunye nogwayimbo lwempuku. Olu khetho lolwakhiwo lulo olwahlula intambo yamandla yemihla ngemihla kwintambo eyenzelwe ukuntywiliselwa okusisigxina okanye ngamaxesha athile.
Zeziphi izinto zokugquma kunye nebhatyi ezinikezela ngeyona ndawo igqwesileyo, ubushushu kunye nokumelana namanzi-?
I-Cross-i-polyethylene edityanisiweyo (XLPE) kunye ne-neoprene edityanisiweyo ngokukodwa okanye i-oyile{1}} kunye namanzi-i-PVC exhathisayo kukuhamba{3}}kwimathiriyeli. I-XLPE ibonelela nge-abrasion egqwesileyo / amandla okuqina kunye nokusebenza kobushushu xa kuthelekiswa nePVC eqhelekileyo; iibhatyi ze-neoprene zongeza ukuchasana okungqiniweyo kwi-oyile, i-ozone kunye nokutshintsha kobushushu - luncedo kwizindlu zempompo kunye nemitsi engcwatyiweyo. Xa ukuntywiliselwa okuqhubekayo kunye nobomi obude bufunekayo, ababoneleli bachaza ii-cores ze-XLPE ezine-neoprene okanye enzima{7}}ibhatyi ye-PVC yomsebenzi (okanye iikhompawundi zobunikazi) ukulungelelanisa ukuguquguquka kunye nokuqina.
Ngaba ndifuna intambo yezixhobo zempompo yam entywilayo? Nini yaye ngoba?
Ukuba intambo iya kuba phantsi kwe-abrasion mechanical, contact rock, ukungcwatywa ngokuthe ngqo, okanye ukufakwa kwii-casings ezinqabileyo, isikrweqe siyacetyiswa. Isikrweqe (i-SWA - isikrweqe socingo lwentsimbi okanye isikrweqe seteyiphu) sinciphisa kakhulu umngcipheko womonakalo womzimba kwaye sandise ubomi benkonzo; ikwaphucula ukuqhubeka kokubekwa phantsi kofakelo oluninzi. Ababoneleli abaphezulu banikezela ngeenguqulelo ezixhobileyo kunye nezingezo{3}}ezingaxhotyisiweyo kwaye baya kucebisa isikrweqe xa ufakelo okanye iimeko zokusebenza zifuna oko.
Zeziphi iimvavanyo kunye neziqinisekiso ekufuneka ndizifune kubaboneleli-nkonzo ukuze ndiqinisekise ubukho bexesha elide?
Cela iingxelo zovavanyo ezishicilelweyo: ukomelela kwedielectric, amanzi{0}}ukuntywiliselwa ukuguga, ukunganyangeki kwe-abrasion, amandla okuqina kunye neconductivity yeconductivity. Kwakhona qinisekisa ukuthotyelwa kwemigangatho evunyiweyo efanelekileyo kwimarike yakho (imizekelo ibandakanya imigangatho yentambo ye-IEC/EN kunye neemfuno zengingqi). Ababoneleli abaphambili bapapasha iziqinisekiso zovavanyo kunye neengxelo zelebhu zomntu wesithathu kula manqaku - agxininisa kuzo kumaxwebhu ethenda.
Ingaba abayili bakhusela njani ukupheliswa kwentambo kunye nendawo yokungena impompo - ukusilela kuhlala kuqala apho, akunjalo?
Ewe - uqhambuko/ukupheliswa yeyona ndawo ixhaphakileyo yokusilela. Eyona ndlela isetyenziswayo ngababoneleli abanamava iquka: umzi-mveliso{2}}ibhutsi ezibunjiweyo ezingangeni manzi okanye amadlala, i-epoxy potting kwindawo yokuqhawuka kwemoto, ubushushu{3}}ukushwabana kwamanzi{4}}izixhobo zokutywina, kunye nentambo ezitywiniweyo ezithelelwe ukuntywiliselwa. Ababoneleli ababonelela ngaphambili{6}}iibhutsi ezitywiniweyo okanye zasefektri{7}}iindibano eziyekiweyo zisikwe{8}}kumngcipheko wesayithi kakhulu.
Yeyiphi iwaranti, ukulandeleka kunye nasemva{0}}inkxaso yokuthengisa ekufuneka ndiyifune?
Ukuthengwa kwe-B2B, kufuna: ubuncinci bewaranti yokuvelisa inyanga ye-12-36 (okanye ixesha elide kwizinto ezibalulekileyo), iziqinisekiso ze-mill / test (izinto eziphathekayo kunye ne-conductor), ukulandelwa kwebhetshi, kunye nenkqubo yempendulo yokusilela ecacileyo (ukutshintshwa, ingcambu{3}}uhlalutyo lwesizathu). Ababoneleli abaphezulu bakwanikezela ngesikhokelo sofakelo, ukwamkelwa{5}}iiprothokholi zovavanyo, kunye nokhetho lwesitokhwe sasekhaya ukunciphisa ixesha lokuphumla. Umthengisi opapasha ufakelo kunye nesikhokelo sovavanyo ubonisa ukukhula kwaye uyawunciphisa umngcipheko wakho osezantsi.
Unxulumanisa njani uhlobo lwentambo yokumpompa kunye neemeko zesayithi - uluhlu olufutshane lokuthenga

Imigangatho novavanyo:Buza i-IEC/UL/EN iingxelo zovavanyo kunye -nezatifikethi zalebhu zomntu wesithathu.
Isampulu & FAT:Ukuthengwa okukhulu cela isampuli kunye nengxelo yovavanyo lwemveliso (IR, i-hipot, i-conductor resistance).
Iwaranti kunye nexesha lokukhokela:Chaza iwaranti,{0}}inxalenye yepolisi esecaleni, kunye nokufumaneka kwesitokhwe sendawo.
Ukulandela la manyathelo kuqinisekisa ukuba uthenga intambo echanekileyo ehlala ixesha elide yomsebenzi.
Ngawaphi amandla omboneleli ahambelana nokuqina{0}}kwexesha elide ebaleni?
Khangela abavelisi abadityanisiweyo ngokuthe nkqo (ukulawula umzobo we-conductor, i-insulation compounding, i-extrusion kunye nezixhobo zokulwa), ababoneleli abanezixhobo zokuvavanya ezipapashiweyo ze-R&D /, kunye nabo banikezela ngenkxaso yobunjineli besicelo kunye nokugcinwa kwendawo. Ababoneleli abapapasha idatadata yemveliso eneenkcukacha, iingxelo zovavanyo kunye nezikhokelo zofakelo (kwaye banezifundo zemizekelo yeeprojekthi ezifanayo) babonisa umngcipheko ophantsi wokuqina{1} kwexesha elide. I-JSHCable kunye nabanye ababoneleli abaqolileyo bapapasha isikhokelo somthengi kunye namaphepha athile abonisa obu buchule.
