Ukuxhathisa oomatshini bokuweldazizixhobo eziyimfuneko kwimveliso yanamhlanje, kwaye uzinzo lwabo lokusebenza kunye nobomi benkonzo ubukhulu becala buxhomekeke kwiinkqubo zabo zokupholisa ezihamba nazo. Into epholileyo, ngakumbi i-chiller, isebenza "njengenkqubo yokuxhasa ubomi" kwi-welder yokumelana. Ijikeleza into epholileyo ukuze isuse ngokufanelekileyo ubushushu obukhulu obuveliswe kwizinto ezingundoqo ezifana nee-electrode, i-transformer, kunye ne-Silicon Controlled Rectifiers ngexesha lenkqubo ye-welding. Ukusilela kwisixokelelwano sokupholisa akusayi kuthoba ngokuthe ngqo kuphela umgangatho we-weld kodwa kunokukhokelela ekuvalweni kobushushu obugqithisileyo kunye nokulibaziseka kwemveliso.
Ke ngoko, ukuqonda ngokucokisekileyo kunye nokusetyenziswa okuchanekileyo kweenkqubo zokupholisa i-welder welder zibalulekile ekuqinisekiseni ukuqhubeka kwemveliso kunye nokwandisa imbuyekezo kutyalo-mali.
I. UkuMatanisa uMmandla wokuPholisa: ISiseko soMbandisi wokuQinisa kunye noKhetho lweNqobo
Ukukhetha izixhobo zokupholisa ezifanelekileyo linyathelo lokuqala ekuqinisekiseni ukusebenza ngokufanelekileyo kwesixhobo sakho sokutshisela ukuxhathisa. Umthamo onganeleyo wokupholisa ngowona nobangela uxhaphakileyo wokufudumeza kwezixhobo. Xa ukhetha inkqubo, ingqwalasela kufuneka ibe kwezi parameters ezingundoqo zilandelayo:
1. Ubalo oluchanekileyo lwesakhono sokupholisa (iToni)
Umthamo wokupholisa sesona salathisi sokusebenza kwe-chiller. Umgaqo owamkelwa ngokubanzi kushishino ngulo:
- Kwi-100 KVA nganye yamandla e-resistance welder, malunga ne-1 toni yomthamo wefriji kufuneka yabelwe.
Itoni enye yomthamo wesikhenkcezisi iphantse ilingane ne-3.5 kilowatts (kW) okanye i-12,000 BTU/iyure yokususa ubushushu. Nangona kunjalo, ubalo oluchane ngakumbi lufuna ukuqwalasela uMjikelo woMsebenzi we-welder kunye nokusebenza kakuhle kokuqokelela ubushushu.
2. IiMfuno eziBalulekileyo zoMgangatho wokuHamba kunye noxinzelelo
Umyinge wokuhamba kunye noxinzelelo lwesipholisi yimiba eqinisekileyo ekusebenzeni kakuhle kokudluliselwa kobushushu.
| Ipharamitha | Uluhlu olucetyiswayo | Umsebenzi obalulekileyo |
| Ireyithi yokuHamba kwamanzi | Ngaphezulu kwe-4 L/min (malunga ne{1}} GPM) | Uqinisekisa ukuba isisipholisi sisusa ngokukhawuleza ubushushu, ngakumbi kwii-electrode kunye ne-transformer. |
| Uxinzelelo lokungena | 0.15 MPa ukuya ku-0.2 MPa (malunga . 22-29 ne-PSI) | Ukoyisa ukuchasana kwisekethe yokupholisa, ukuqinisekisa ukuba amanzi afikelela kuzo zonke iindawo zokupholisa. |
| Ububanzi bombhobho | Kufuneka ihlangabezane neemfuno zokuhamba | Imibhobho emxinwa kakhulu ibangela ilahleko yoxinzelelo kunye nokungonelanga kokuhamba, kubeke esichengeni ukusebenza okupholisayo. |
Ukuhamba kunye noxinzelelo ziyahambelana. Amandla wempompo ye-chiller (umzekelo, amandla ehashe okanye i-kW) kufuneka omelele ngokwaneleyo ukuhambisa umlinganiselo wokuqukuqela ofunekayo ngelixa ugcina uxinzelelo olwaneleyo lokoyisa uxhathiso lwalo lonke isekethi yokupholisa (kubandakanywa amalungu angaphakathi ewelder, imibhobho, kunye nezihluzi).
II. Ulawulo lokupholisa: Umgangatho waManzi yiNkqubo "yeGazi"
Umgangatho wesipholisi uchaphazela ngokuthe ngqo ukusebenza kakuhle kwenkqubo yokupholisa kunye nobomi bamalungu angaphakathi e-welder. Ukusebenzisa umgangatho wamanzi okumgangatho ophantsi ngoyena nobangela wesibini uxhaphakileyo wokusilela kwenkqubo yokupholisa.
1. Iimpawu zoMgangatho waManzi ezingundoqo kunye neMigangatho
Izixhobo zokuwelda ezixhathisayo, ngakumbi iiwelder zeMedium Frequency Inverter (MFI) zifuna umgangatho wamanzi ophezulu kakhulu ukuthintela umhlwa, ukukala, kunye nokuvuza kombane.
| Isalathisi soMgangatho waManzi | Umgangatho ocetyiswayo | Impembelelo kunye neziphumo |
| Ixabiso le-pH | 7.0 - 9.0 | Iphantsi kakhulu (i-acidic) ibangela ukubola; phezulu kakhulu (i-alkaline) ikhuthaza ukukala. |
| Ukuqhuba | Kucetyiswa ngaphantsi kwe-200 μS / cm | Ukuqhuba okuphezulu konyusa ukuhanjiswa kombane kwesisipholisi, okunokukhokelela-ekuvuza okuphindaphindiweyo kwangoku kunye nomonakalo kwizinto zombane ezifana ne-SCRs/IGBTs. |
| Ukuqina | Sebenzisa amanzi athambekile okanye adiyoni | Ubunzima obuphezulu bubangela ukuba idiphozithi ye-calcium kunye ne-magnesium ion, yenze isikali kutshintshiselwano lobushushu kunye nemibhobho, ukunciphisa kakhulu ukusebenza kakuhle kokudluliselwa kobushushu. |
| Uhluzo | Iimicrons ezingama-50 okanye ngaphezulu | Uhluzo lwe-particulate matter, ukuthintela ukuvaleka kwimibhobho kunye neepompo. |
Isindululo: Amanzi adiyiweyo okanye adiyiweyo kufuneka asetyenziswe njengesipholisi, kunye nokongezwa rhoqo kwee-specied inhibitors ze-corrosion kunye ne-scale inhibitors ukugcina uzinzo kubulunga bamanzi.
2. Ukhuseleko lweNdawo yombethe: Ukuthintela iCandelo "Ukubila"
Inkqubo yokusebenza ebaluleke kakhulu, kodwa ehlala ingahoywa, luKhuseleko lweNdawo yombethe. Ukuba ubushushu besipholisi bubekwe phantsi kakhulu{1}}ngaphantsi kweqondo lombethe lomoya{2}}umphunga wamanzi emoyeni uya kuxinana kumphezulu wemigca yokupholisa yangaphakathi yewelder kunye nezinto zombane (ezifana nemodyuli yesiguquli kunye ne-SCR), into eyaziwa ngokuba yi "sweating" okanye "condensation".
- Isiphumo:Amathontsi e-condensation anokubangela iibhulukhwe zombane kumalungu e-elektroniki, okukhokelela kukusilela kwezixhobo eziyingozi.
- Ukusebenza okuchanekileyo:
- Ubume beqondo lobushushu: Iqondo lokupholisa kufuneka lihlale likwinqanaba lesi-3 ukuya kwisi-5 iqondo lobushushu bombethe.
- Uluhlu lweqondo lobushushu: Ngelixa ubushushu obulawulekayo kwiqondo lokupholisa buqhelekile kwi-5-30 degree, kuyacetyiswa ukuba kugcinwe ubushushu bamanzi phakathi kwe-15℃kunye ne-25℃kwimveliso yokwenyani ukulungelelanisa ukusebenza kakuhle kokupholisa kunye nomngcipheko wendawo yombethe.
III. IiNkqubo zokuSebenza kunye noLuhlu lokuHlola lweMimiselo
Ukuthotyelwa okungqongqo kwiinkqubo zokusebenza kunye nokuzalisekisa isicwangciso sokulungisa esisebenzayo ziziseko zozinzo{0}}zexesha elide lwenkqubo yokupholisa.
1. UkuQala okuchanekileyo kunye noKuvala ulandelelwano
Ulandelelwano lokuqalisa:

Ukuqukumbela
Ukubaluleka kwenkqubo yokupholisa i-resistance welder ayikwazi ukugqithiswa. Ayisosincedisi esibalulekileyo kuphela sokuqinisekisa umgangatho we-weld kodwa kwakhona lutyalo-mali olungundoqo ekwandiseni ubomi bezixhobo ezibizayo. Ngokubambelela kwiikhrayitheriya zokukhetha zenzululwazi (ezifana nokutshatisa i-KVA kwitoni), ukulawula ngokungqongqo umgangatho wokupholisa (ukulawula i-pH kunye nokuhamba, ukuthintela ukuxinana), kunye nokuqhuba ngokuqhubekayo isicwangciso sokulungisa esisebenzayo, unokunciphisa kakhulu amazinga okusilela, uqinisekise imveliso ezinzileyo, kwaye wandise imbuyekezo yesixhobo sakho kutyalo-mali.
