Isiseko: Kutheni iintsuku ezingama-90 zaziqhelekile kwiSão Paulo Sugar Mill Vane Pumps

Le matshini yokugaya isetyenziswa njenge-São Paulo sugar and ethanol ephakathi, esebenza iiyure ezingama-24 ngosuku, iintsuku ezisixhenxe ukususela ngo-Epreli ukuya kuNovemba. Le mishini yokugaya isebenzisa iipompo ze-Vickers V series double vane kwi-pressure circuits ezintathu: i-mill roll, i-imbibition, kunye ne-bagasse handling. Ngaphambi kokuba ilungiswe, yonke i-V series cartridge yayiyekiswa ukusebenza emva kweentsuku ezingama-90 nokuba isetyenziswa na.

Loo mjikelo weentsuku ezingama-90 awuqhelekanga kwiifektri zeswekile zaseBrazil. Iifektri ezikwimimandla yetropiki kushishino lonke zibona imijikelo yeentsuku ezingama-60-90 kwiimpompo ze-vane eziqhelekileyo. Ingxaki ayikokusilela kwangethuba - kukuba amaxesha okutshintshana kweentsuku ezingama-90 abeka ukutshintshwa kwempompo kwixesha lokuvuna, apho ixesha lokungasebenzi libiza kakhulu.

"Isivuno se-snake machine eSão Paulo siqala ngo-Epreli ukuya kuNovemba, iiyure ezingama-24/7. Umjikelo we-pump weentsuku ezingama-90 uthetha ukutshintshana kwe-pump okucwangcisiweyo kathathu ukuya kwezine ngexesha lokuvuna. Ukutshintshana ngakunye kuthatha iiyure ezine ukuya kwezintandathu zokungasebenzi kwe-mill. Elo lixabiso elalifuneka lilungiswe yi-OEM spec."

Iinguqu Ezintathu Eziye Zaphinda Ubomi Bepompo

Utshintsho olwenziwe ngamanyathelo amathathu kwi-OEM spec, hayi i-pump swap. I-pump ngokwayo ifana kakhulu ne-V series SKU; iinkcukacha ezijikelezileyo yizo ezitshintshileyo. Ezi nguqu zintathu zicwangciswe ngokwempembelelo, apho elokuqala linegalelo elikhulu kwaye elesithathu liyi-inshurensi ebiza kancinci.

2.1 Utshintsho 1 – I-Hydraulic fluid spec: ukusuka kwi-ISO VG 46 eqhelekileyo ukuya kwi-oyile ene-VI ephezulu engama-50°C

Eyona nto inegalelo elikhulu yayikukutshintsha kolwelo lwe-hydraulic. Le matshini yayisebenzisa ioyile yeminerali ye-ISO VG 46 eqhelekileyo (VI ~95, ubushushu obukhulu obuyi-60°C). Kwisivuno saseSão Paulo, amaqondo obushushu obuninzi edamini afikelela kwi-55°C phakathi kwemini. Kwi-55°C, i-ISO VG 46 incipha ukuya kwi-13-14 cSt - kanye kumda osezantsi wefestile yokusebenza ye-V series.

I-retrofit fluid yi-high-VI hydraulic oil (VI 150+) ene-ISO VG 46 cold-side rating efanayo kodwa i-viscosity-versus-temperature curve ethe tyaba kakhulu. Kwi-55°C ibamba i-18-20 cSt, ngokukhululeka ngaphakathi kwefestile ye-V series. Ifilimu ye-fluid kwi-vane tips ihlala injalo kwixesesha elishushu lemini, izinga lokuguguleka liyehla, kwaye ubomi be-cartridge buphindaphindeka kabini.

2.2 Utshintsho 2 – Ukucoca: ukusuka kwi-25-micron nominal ukuya kwi-10-micron absolute return-line

Utshintsho lwesibini yayikukuqinisa ukucoca umgca wokubuyisela. I-mill isebenzise isihluzi sokubuyisela esiqhelekileyo se-25-micron (esiqhelekileyo se-OEM, esifanelekileyo kwiimozulu ezishushu). ESão Paulo, amaqondo obushushu aphezulu edama akhawulezisa ukubola kweoyile, kwaye iimveliso eziphuma kwi-oxidation ziwela kuluhlu lwe-5-15 micron - apho isihluzi esiqhelekileyo se-25-micron sidlula khona.

I-retrofit itshintshelwe kwisihluzi se-10-micron absolute return-line filter (β10 ≥ 200, i-99.5 yepesenti yokubamba kwi-10 microns). Ukubamba okuphezulu kugcina iimveliso eziphuma kwi-oxidation zingangeni kwindawo yokuguguleka kwe-vane kwaye kwandisa ubomi be-cartridge nge-30-40 yepesenti ngokwayo. Ixabiso lokutshintsha isihluzi lincinci - into enye ngekota.

2.3 Utshintsho 3 – Ikhatriji yepompo: ukusuka kuthotho lwe-VQ ukuya kuthotho lwe-V kwiisekethe ezishushu

Utshintsho lwesithathu belulolona luncinci ngexabiso kodwa lolona lunolwazi. I-mill yayine-specified VQ series pumps kwi-bagasse circuit. I-VQ isebenza kakuhle kakhulu kodwa i-viscosity window incinci (13-54 cSt vs V series' 13-143 cSt). Xa amaqondo obushushu e-reservoir enyuka, ii-VQ pumps zichithe iiyure ezingaphezulu kune-viscosity yoyilo, kwaye kwalandela ukuguguleka.

Ukutshintshela kwikhatriji eqhelekileyo ye-V series kunike ipompo ifestile yokusebenza ebanzi kakhulu. I-V series ayisebenzi kakuhle kwindawo yoyilo, kodwa ilahleko yokusebenza eyi-2-3 ekhulwini incinci xa ithelekiswa nokwanda kokuqina. I-mill ngoku isebenzisa i-VQ kwiisekethe ezizinzileyo kunye ne-V kwisekethe ye-bagasse apho amaqondo obushushu etshintsha khona.

I-Arithmetic yeendleko eqinisekisa ukubuyiswa kwakhona

Iinjineli ze-hydraulic ze-São Paulo sugar mill ziyayivuma i-retrofits kwi-payback, hayi kwi-elegance. Izibalo zale retrofit zilula.

3.1 Icandelo leendleko zepompo

Ikhatriji yochungechunge lwe-V ithengiswa malunga ne-USD 220 kwitshaneli ye-OEM yaseBrazil. Le fektri yayithenga iikhatriji ezili-12 ngonyaka (enye ngekota ngesekethe nganye, iisekethe ezintathu). Emva kokulungiswa kwayo ithenga ezi-6. Ukonga ngokuthe ngqo kwipompo: malunga ne-USD 1,320 ngonyaka.

3.2 Icandelo leendleko zexesha lokuphumla

Utshintsho ngalunye lwepompo luthatha iiyure ezi-4-6 zokungasebenzi komatshini wokusila. Lo matshini usebenza kwiitoni ezili-12,000 zomoba ngosuku. Utshintsho olungacwangciswanga lweeyure ezi-4 lubiza malunga ne-USD 15,000 kwingeniso yeswekile elahlekileyo kunye nezohlwayo zabathengi be-ethanol. Ukunciphisa i-swaps ngesiqingatha kusindisa i-USD 45,000-60,000 ngonyaka ngexesha lokungasebenzi.

3.3 Icandelo leendleko zomonakalo wesibini

Ipompo ye-vane engaphumeleliyo phakathi kwe-shift ilahla iziqwenga kwi-reservoir nakwinxalenye yesekethe. Ukucoca kuxabisa i-USD 5,000-10,000 ngesiganeko ngasinye. Ukulungisa kwangaphambili i-mill yayineziganeko ezinjalo ezi-1-2 ngesivuno ngasinye. Ukulungisa emva kwe-retrofit: zero kunyaka wokuqala.

Oko Kuthethwa "yi-Hot-Climate OEM Spec" kwiPhepha leeNkcukacha

I-"Hot-climate OEM spec" sisishwankathelo senkcazelo ebhaliweyo ejongana namaqondo obushushu ahlala ixesha elide angaphezulu kwama-50°C kunye nendawo engqongileyo engaphezulu kwama-35°C. Uninzi lwamaphepha edatha e-OEM afihla ibali lokwenyani: kwisiphelo esiphezulu soluhlu lwamaqondo obushushu, i-fluid viscosity kunye nokuguguleka kwepompo zinobuthathaka kakhulu ekukhethweni kolwelo. I-hot-climate spec yenza ezo mvakalelo zicace.

Imigangatho ye-ISO VG kunye ne-DIN 51524 emva kweSpec

Utshintsho lwe-fluid spec lusebenzisa iireferensi ezintathu zoshishino.Isikhokelo sokukhetha ulwelo lweBosch Rexrothibeka isakhelo se-DIN 51524 se-ISO VG 32/46/68/100 ii-hydraulic oils ezineetshathi ezicacileyo ze-viscosity-vs-temperature.Isalathiso sokuthambisa seYuniliamaxwebhu HLP, HVLP, kunye HV viscosity amabakala (HVLP/HV at VI ≥ 150, HLP at VI ~95-105). IIsalathiso sokukhetha i-ISO VGiqinisekisa ukuba kutheni i-VI ≥ 140 iyimfuneko kwinkonzo yamanzi ashushu. Ukulungiswa kwakhona kukwicandelo le-HVLP.

4.1 Iindawana ezintlanu ekufuneka i-OEM spec izivalele kwimozulu eshushu

1. Ubushushu obuphezulu bolwelo (ithagethi ≥ 16 cSt xa iphezulu, hayi xa iqalisa ukubanda).
2. Isalathisi se-Fluid viscosity (ithagethi VI ≥ 150 yokusebenza okuqhubekekayo kwama-50°C+).
3. Uvavanyo olupheleleyo lokuhluza umgca wokubuyisela (ithagethi ≤ 10 micron ene-β10 ≥ 200).
4. Ubungakanani bedama lokulahla ubushushu obuphezulu (ithagethi ≥ 3 × ixesha lokuhamba kwepompo lokuhlala).
5. Ukukhethwa kochungechunge lwekhatriji ngesekethe nganye (V vs VQ vs T6 vs T7 ihambelana nebhendi yobushushu).

4.2 Oko uninzi lweenkcukacha ze-OEM zingakukhankanyiyo

Uninzi lwamaphepha edatha e-OEM akhankanya ukusebenza kwindawo yoyilo - ubushushu obukhulu obuyi-50°C kunye neoyile yeminerali ye-ISO VG 46. Elo phepha ledatha lilungile kwiindawo ezinobushushu obuphantsi kodwa liyakhohlisa kwizicelo zaseSão Paulo okanye eTexas. I-specific yemozulu eshushu iphinda ichaze ukusebenza phantsi kobushushu bokwenyani kunye nolwelo.

Kutheni iNingbo Vicks Hydraulic iLiqabane elifanelekileyo le-OEM kule hlobo lokuphucula izinto?

Ukulungiswa kwakhona kwacwangciswa kwaye kwabonelelwa yiNingbo Vicks Hydraulic Co., Ltd., eyasekwa ngo-2007 njengeshishini lesizwe eliphambili lobuchwephesha eligxile kwiinkqubo ze-vane pump kunye neenkqubo ze-servo ezonga amandla.
