Gwaro rekuisa zvinhu padivi remukondirakita: hunhu hwekugadzirisa maturusi hunoona mashandiro epadhi kwenguva refu, magwaro matanhatu emutengesi ekukumbira usati waburitsa zvinhu, nzira yekushanda inoshanda panguva yekushanda, uye magwaro anokudzivirira pakugadzwa kwewaranti.
TL;DR — Ongororo yekutarisa zvinhu zvisati zvaiswa nekondirakita
- Chigadziko chemagetsi chinobata basa remagetsi, kwete tsvimbo.Electrode yemugayiwa ine makemikari isimbi inoputirwa nemhangura iri mukati mekoramu ye hygroscopic backfill. Iyo backfill ndiyo inoita kuti pad isarambe yakasimba panguva yemwaka wehunyoro.
- Kumbira magwaro matanhatu usati waburutsa zvinhu.Mushumo wekuyedza mhando (kuderedza resistivity, ionic stability pa60 °C / mazuva makumi matatu, kuchengetedza hunyoro, ESIA compliance), IEC 62561-7 statement, NEMA GR-1 cert, IEEE 837 connector statement, lot numbers, install guide mumutauro wevashandi vekuisa.
- Dhayamita yeAuger ndiyo shanduko huru pane dzose dziri padivi rekuisa.Pakutumira kweShiBang's ME kubva 2020-2025, maerekitirodhi ekutanga mazana maviri ane auger ye75 mm akaverenga avhareji ye5.8 Ω zvichienzaniswa nechinangwa che5 Ω; mamwe 4,000 ane auger ye100 mm akaverenga avhareji ye3.1 Ω. 0.4 Ω delta, kubva kune kontrakita ari ega.
- Nyora zvese zvaunoda pawaranti yegore rechitatu.Magwaro emutengesi, dhizaini yakagadzirwa ine nzvimbo dzemagetsi nenhamba dzenzvimbo, mapikicha ekuisa, kuverenga kunogona kudonha panguva yekushanda. Mukondirakita anongopa kuverenga kwepad chete haana dziviriro.
Furemu yandinoda kusimbisa nyaya iyi ndeye waranti yemukondirakiti. Kana electrode yemakemikari yapwanyika ikapfuura nepahwindo remagetsi ekubata mugore rechitatu kana rechina - uye ikadaro, panzvimbo dzaive dzisina kurongeka - EPC nemuridzi wepurojekiti vanotevera kutadza kuburikidza necheni yewaranti. Mukondirakiti akaisa electrode ndiye munhu anogona kutora mari yekugadzirisa, nekuti waranti yemutengesi inowanzo bvisa hunyanzvi hwemukondirakiti uye rekodhi yemukondirakiti ndiyo yega gwaro rinoratidza kuti kuisa kwacho kwakafanana nezvinodiwa. Mukondirakiti anongopa kuverenga kwe commissioning pad - asina gwaro remutengesi, dhirowa rakagadzirwa, mapikicha ekuisa, uye nhamba dze batch dzinogona kuteverwa - haana dziviriro kana bvunzo yegore-rechitatu ikadzoka pamusoro pechinangwa.
Chinyorwa ichi chakafanana nemagwaro anodzivirira mugadziri wezvinhu. Chakanyorwa kune mukuru wekugadzira zvinhu uye mutariri wenzvimbo, kwete mainjiniya wekutenga zvinhu weEPC. Nyaya yacho inyaya yekuisa zvinhu kubva panguva iyo zvinhu zvinosvika panzvimbo kuburikidza nekuyedzwa kwekukwanisa kuvhurwa - uye padanho rega rega, zvinodiwa nemugadziri, kunyora nekuchengeta.
