Isiguquli semvamisaiyithuluzi lokulawula amandla eliguqula ukunikezwa kwamandla kagesi kwesinye imvamisa ngokusebenzisa isenzo sokucisha samadivayisi wesemiconductor yamandla.Ngokuthuthuka okusheshayo kobuchwepheshe besimanje bamandla kagesi kanye nobuchwepheshe be-microelectronics,high voltage kanyeamadivaysi okulawula isivinini sokuguqula imvamisa ephezuluukuqhubeka nokuvuthwa, okwangempela kube nzima ukuxazulula inkinga ye-voltage ephezulu, eminyakeni yamuva ngochungechunge lwedivayisi noma uchungechunge lwamayunithi kube yisixazululo esihle.
Idivayisi yokulawula isivinini se-voltage ephezulu namandla aphezulu aguquguqukayoisetshenziswa kabanzi embonini enkulu yokukhiqiza izimayini, i-petrochemical, amanzi kamasipala, insimbi yensimbi, amandla kagesi kanye nezinye izimboni zazo zonke izinhlobo zabalandeli, amaphampu, ama-compressor, imishini yokugoqa nokunye.
Imithwalo yamaphampu, esetshenziswa kakhulu ezimbonini ezifana nensimbi, imboni yamakhemikhali, amandla kagesi, ukuphakelwa kwamanzi kamasipala nezimayini, yenza cishe amaphesenti angama-40 okusetshenziswa kwamandla azo zonke izinto zikagesi, kanti isikweletu sikagesi sifinyelela ku-50% izindleko zokukhiqiza amanzi emisebenzini yamanzi.Lokhu kungenxa yokuthi: ngakolunye uhlangothi, okokusebenza kuvame ukuklanywa ngomphetho othile;Ngakolunye uhlangothi, ngenxa yokushintsha kwezimo zokusebenza, ipompo idinga ukukhipha amazinga okugeleza ahlukene.Ngokuthuthukiswa komnotho wemakethe kanye ne-automation, ukuthuthukiswa kwezinga lobuhlakani, ukusetshenziswa kwehigh voltage frequency converterukulawula ijubane umthwalo futha, hhayi nje ukuthuthukisa inqubo, ngcono izinga lomkhiqizo muhle, kodwa futhi nezidingo ukonga amandla kanye nemishini yokusebenza kwezomnotho, kuyindlela engenakugwenywa yentuthuko esimeme.Kunezinzuzo eziningi zokulawula isivinini semithwalo yepompo.Kusukela ezibonelweni zohlelo lokusebenza, iningi labo lithole imiphumela emihle (okunye ukonga amandla kuze kufike ku-30% -40%), kunciphisa kakhulu izindleko zokukhiqiza amanzi emanzini, ukuthuthukisa izinga le-automation, futhi kulungele ukusebenza kokuya phansi. yenethiwekhi yephampu namapayipi, ukunciphisa ukuvuza nokuqhuma kwamapayipi, kanye nokwelula isikhathi sokusebenza kwezinto zokusebenza.
Indlela kanye nesimiso sokulawulwa kokugeleza komthwalo wohlobo lwepompo, Umthwalo wepompo uvame ukulawulwa izinga lokugeleza kwamanzi okulethwayo, ngakho-ke izindlela ezimbili zokulawula i-valve nokulawula isivinini zivame ukusetshenziswa.
Ukulawula i-valve
Le ndlela ilungisa izinga lokugeleza ngokushintsha usayizi wokuvula i-valve yokuphuma.Kuyindlela yomshini osekunesikhathi eside ikhona.Ingqikithi yokulawula i-valve ukushintsha usayizi wokumelana noketshezi epayipini ukushintsha izinga lokugeleza.Ngenxa yokuthi ijubane lephampu alishintshile, ijika lesici sekhanda layo le-HQ lihlala lingashintshile.
Uma ivalvu ivuleke ngokugcwele, ijika lesici sokumelana namapayipi i-R1-Q kanye nejika lesici sekhanda i-HQ liphambana ephuzwini A, izinga lokugeleza yi-Qa, kanye nekhanda lokucindezela kokuphuma kwephampu ngu-Ha.Uma i-valve yehliswa, ijika lesici sokumelana nepayipi liba ngu-R2-Q, indawo yokuphambana phakathi kwayo nejika lesici sekhanda i-HQ iya endaweni engu-B, izinga lokugeleza yi-Qb, futhi ikhanda lokucindezela kokuphuma kwephampu likhuphukela ku-Hb.Khona-ke ukwanda kwekhanda lokucindezela kungu-ΔHb=Hb-Ha.Lokhu kuphumela ekulahlekelweni kwamandla okuboniswa kulayini onegethivu: ΔPb=ΔHb×Qb.
2.Ukulawula isivinini
Ngokushintsha isivinini sepompo ukuze ulungise ukugeleza, lena indlela yokulawula ye-elekthronikhi ethuthukisiwe.Ingqikithi yokulawula isivinini ukushintsha izinga lokugeleza ngokushintsha amandla oketshezi olulethiwe.Ngoba izinguquko zejubane kuphela, ukuvulwa kwe-valve akushintshi, futhi ijika lesici sokumelana nepayipi R1-Q lihlala lingashintshiwe.Ijika lesici sekhanda i-HA-Q ngesivinini esilinganiselwe linqamula ijika lesici sokumelana nepayipi endaweni engu-A, izinga lokugeleza yi-Qa, kanye nenhloko yokuphumayo ngu-Ha.Lapho ijubane lincipha, ijika lesici sekhanda liba i-Hc-Q, futhi iphuzu lokuhlangana phakathi kwalo kanye nejika lesici sokumelana nepayipi i-R1-Q lizokwehla liye ku-C, futhi ukugeleza kuba Qc.Ngalesi sikhathi, kucatshangwa ukuthi ukugeleza kwe-Qc kulawulwa njengokugeleza kwe-Qb ngaphansi kwemodi yokulawula i-valve, khona-ke inhloko yokuphuma yepompo izokwehliswa ibe yi-Hc.Ngakho, ikhanda lokucindezela liyancishiswa uma kuqhathaniswa nemodi yokulawula i-valve: ΔHc = Ha-Hc.Ngokwalokhu, amandla angagcinwa njengalokhu: ΔPc=ΔHc×Qb.Uma kuqhathaniswa nemodi yokulawula i-valve, amandla alondoloziwe yilawa: P=ΔPb+ΔPc=(ΔHb-ΔHc)×Qb.
Ukuqhathanisa lezi zindlela ezimbili, kungabonakala ukuthi esimweni sokugeleza okufanayo, ukulawulwa kwejubane kugwema ukulahlekelwa amandla okubangelwa ukwanda kwekhanda lokucindezela kanye nokwanda kokumelana kwamapayipi ngaphansi kokulawula i-valve.Uma izinga lokugeleza lincishisiwe, ukulawula isivinini kubangela ukuba i-indenter inciphise kakhulu, ngakho idinga kuphela ukulahlekelwa kwamandla okuncane kakhulu kunokulawula kwe-valve ukuze kusetshenziswe ngokugcwele.
Ihigh voltage inverterekhiqizwa i-Noker Electric isetshenziswa kakhulu kubalandeli, amaphampu, amabhande nezinye izikhathi, futhi umphumela wokonga amandla uyabonakala, oye waqashelwa amakhasimende.
