Isiguquli rhoqosisixhobo solawulo lwamandla esiguqula unikezelo lwamandla ombane ukuya kwesinye isikhewu ngokusebenzisa isenzo sokucinywa kwezixhobo zesemiconductor yamandla.Ngophuhliso olukhawulezayo lwetekhnoloji yamandla anamhlanje kunye netekhnoloji ye-microelectronics,amandla ombane aphezulu kunyeizixhobo zolawulo lwesantya sokuguqulwa kwamandla aphezuluukuqhubeka nokuvuthwa, i-original bekunzima ukusombulula ingxaki yombane ophezulu, kwiminyaka yakutshanje ngokusebenzisa uchungechunge lwesixhobo okanye uchungechunge lweyunithi ibe sisisombululo esihle.
Isixhobo sokulawula isantya esiphezulu samandla ombane kunye namandla aphezulu aguquguqukayoisetyenziswa ngokubanzi kwiplanti enkulu yokuvelisa imigodi, i-petrochemical, unikezelo lwamanzi kamasipala, intsimbi ye-metallurgical, amandla ombane kunye namanye amashishini azo zonke iintlobo zabalandeli, iimpompo, i-compressors, oomatshini abaqengqelekayo njalo njalo.
Imithwalo yempompo, esetyenziswa kakhulu kumashishini afana nesinyithi, ishishini lemichiza, amandla ombane, unikezelo lwamanzi lukamasipala kunye nemigodi, libalelwa malunga ne-40% yokusetyenziswa kwamandla kuzo zonke izixhobo zombane, kwaye ibhili yombane ithatha i-50% yombane. ixabiso lemveliso yamanzi kwimizila yamanzi.Oku kungenxa yokuba: kwelinye icala, isixhobo siqhele ukuyilwa ngomda othile;Ngakolunye uhlangothi, ngenxa yokutshintsha kweemeko zokusebenza, umpompo kufuneka ukhuphe amazinga ahlukeneyo okuhamba.Ngophuhliso loqoqosho lwemarike kunye ne-automation, ukuphuculwa kweqondo lobukrelekrele, ukusetyenziswa kweisiguquli samaza ombane aphezuluukulawulwa kwesantya somthwalo wempompo, kungekuphela nje ukuphucula inkqubo, ukuphucula umgangatho wemveliso kulungile, kodwa kunye neemfuno zogcino lwamandla kunye nokusebenza kwezoqoqosho kwezixhobo, yinto engenakuphepheka yophuhliso oluzinzileyo.Kukho iinzuzo ezininzi zokulawula isantya somthwalo wempompo.Ukususela kwimizekelo yesicelo, uninzi lwabo lufumene iziphumo ezilungileyo (amandla athile agcina amandla ukuya kuthi ga kwi-30% -40%), ukunciphisa kakhulu iindleko zokuvelisa amanzi kumanzi asebenzayo, ukuphucula iqondo lokuzenzekelayo, kunye nokulungelelaniswa komsebenzi wokuhla. womnatha wempompo kunye nombhobho, ukunciphisa ukuvuza kunye nokudubula kombhobho, kunye nokwandisa ubomi benkonzo yezixhobo.
Indlela kunye nomgaqo wolawulo lokuhamba komthwalo wohlobo lwempompo, Umthwalo wempompo udla ngokulawulwa yisantya sokuhamba kwamanzi okuhanjiswayo, ngoko ke iindlela ezimbini zokulawula i-valve kunye nokulawulwa kwesantya zisetyenziswa rhoqo.
1.Ulawulo lweValve
Le ndlela ilungisa izinga lokuhamba ngokutshintsha ubungakanani bokuvulwa kwevalve yokuphuma.Yindlela yomatshini esele ikhona ixesha elide.Undoqo wolawulo lwevalvu kukutshintsha ubungakanani bokunganyangeki kwamanzi kumbhobho ukutshintsha isantya sokuhamba.Ngenxa yokuba isantya sempompo asitshintshanga, intloko yayo igophe ye-HQ ihlala ingatshintshi.
Xa ivalve ivuleke ngokupheleleyo, igophe lokumelana nombhobho i-R1-Q kunye nentloko yegophe ye-HQ inqumla kwindawo A, izinga lokuhamba yi-Qa, kunye nentloko yoxinzelelo lwempompo yiHa.Ukuba ivalve ijikisiwe, igophe lokumelana nombhobho liba yi-R2-Q, indawo yokuhlangana phakathi kwayo kunye nentloko ye-curve ye-HQ ishukuthela kwindawo ye-B, isantya sokuhamba yi-Qb, kunye nentloko yoxinzelelo lwempompo iphakama ukuya kwi-Hb.Emva koko ukunyuka kwentloko yoxinzelelo ngu-ΔHb = Hb-Ha.Oku kubangela ukulahlekelwa kwamandla kuboniswe kumgca ongalunganga: ΔPb=ΔHb×Qb.
2.Ulawulo lwesantya
Ngokutshintsha isantya sempompo ukulungelelanisa ukuhamba, le yindlela yokulawula i-electronic advanced.Undoqo wolawulo lwesantya kukutshintsha isantya sokuqukuqela ngokutshintsha amandla olwelo oluhanjiswayo.Ngenxa yokuba isantya sitshintsha kuphela, ukuvulwa kwevalve akutshintshi, kwaye igophe lokumelana nombhobho R1-Q lihlala lingatshintshi.Igophe leempawu zentloko i-HA-Q ngesantya esilinganiselweyo sinqumla igophe lophawu lokumelana nombhobho kwindawo A, izinga lokuhamba yi-Qa, kunye nentloko yokuphuma nguHa.Xa isantya siyancipha, ijika leempawu zentloko liba yi-Hc-Q, kwaye indawo yokuhlangana phakathi kwayo kunye negophe lokumelana nombhobho we-R1-Q iya kuhla ukuya kwi-C, kwaye ukuhamba kuba yi-Qc.Ngeli xesha, kucingelwa ukuba ukuhamba kwe-Qc kulawulwa njengokuhamba kwe-Qb phantsi kwendlela yokulawula i-valve, emva koko intloko yokuphuma yepompo iya kuncitshiswa ibe yi-Hc.Ngaloo ndlela, intloko yoxinzelelo iyancitshiswa xa kuthelekiswa nemodi yokulawula i-valve: ΔHc = Ha-Hc.Ngokwale nto, amandla anokugcinwa njenge: ΔPc=ΔHc×Qb.Xa kuthelekiswa nemowudi yokulawula ivalve, amandla agciniweyo: P=ΔPb+ΔPc=(ΔHb-ΔHc)×Qb.
Ukuthelekisa iindlela ezimbini, kunokubonwa ukuba kwimeko yesantya esifanayo sokuhamba, ukulawulwa kwesantya kunqanda ukulahlekelwa kwamandla okubangelwa ukunyuka kwentloko yoxinzelelo kunye nokunyuka kokumelana kombhobho phantsi kolawulo lwevalve.Xa isantya sokuhamba sincitshiswa, ulawulo lwesantya lubangela ukuba i-indenter incitshiswe kakhulu, ngoko ifuna kuphela ukulahlekelwa kwamandla amancinci kunokuba i-valve isetyenziswe ngokupheleleyo.
Ii-inverter yombane ophezulueveliswe nguNoker Electric isetyenziswa kakhulu kubalandeli, iimpompo, amabhande kunye nezinye izihlandlo, kwaye umphumo wokonga amandla uyabonakala, oye wamkelwa ngabathengi.
