1.Kuwongolera ma valve
Njirayi imasintha kuthamanga kwa kuthamanga mwa kusintha kukula kwa kutsegula kwa valve.Ndi njira yamakina yomwe yakhalapo kwa nthawi yayitali.Chofunika kwambiri cha kuwongolera ma valve ndikusintha kukula kwa kukana kwamadzimadzi mu payipi kuti musinthe kuthamanga.Chifukwa liwiro la mpope silinasinthidwe, mutu wake wokhotakhota HQ sunasinthe.
Vavu ikatsegulidwa kwathunthu, chitoliro chokana chitoliro cha R1-Q ndi mutu wokhotakhota wa HQ umadutsa pamalo A, kuthamanga kwake ndi Qa, ndipo mutu wapampopi wotuluka ndi Ha.Ngati valavu yatembenuzidwira pansi, chitoliro chotsutsana ndi chitoliro chimakhala R2-Q, malo ophatikizirapo pakati pake ndi mutu wamtundu wa HQ umasunthira kumalo B, kuthamanga kwa Qb, ndipo mutu wothamanga wa mpope umakwera mpaka Hb.Ndiye kuwonjezeka kwa mutu wopanikizika ndi ΔHb = Hb-Ha.Izi zimabweretsa kutayika kwa mphamvu komwe kumawonetsedwa pamzere woyipa: ΔPb = ΔHb×Qb.
2.Kuwongolera liwiro
Mwa kusintha liwiro la mpope kuti musinthe kayendetsedwe kake, iyi ndi njira yoyendetsera magetsi.Chofunikira cha kuwongolera liwiro ndikusintha kuchuluka kwamayendedwe posintha mphamvu yamadzimadzi yoperekedwa.Chifukwa kuthamanga kokha kumasintha, kutsegula kwa valavu sikumasintha, ndipo kukana kwa chitoliro cha R1-Q kumakhala kosasintha.Mutu wokhotakhota wa HA-Q pa liwiro lovotera umadutsana ndi mayendedwe otsutsana ndi chitoliro pamalo A, kuthamanga kwake ndi Qa, ndipo mutu wotuluka ndi Ha.Pamene liwiro limachepa, mutu khalidwe pamapindikira amakhala Hc-Q, ndi mphambano mfundo pakati pa izo ndi chitoliro kukana khalidwe pamapindikira R1-Q kusuntha mpaka C, ndi otaya amakhala Qc.Panthawiyi, zimaganiziridwa kuti kutuluka kwa Qc kumayendetsedwa ngati kutuluka kwa Qb pansi pa njira yoyendetsera valve, ndiye kuti mutu wotuluka wa mpope udzachepetsedwa kukhala Hc.Choncho, mutu wopanikizika umachepetsedwa poyerekeza ndi njira yoyendetsera valve: ΔHc = Ha-Hc.Malinga ndi izi, mphamvuyo imatha kupulumutsidwa monga: ΔPc=ΔHc×Qb.Poyerekeza ndi mawonekedwe a valve, mphamvu yopulumutsidwa ndi: P = ΔPb + ΔPc = (ΔHb-ΔHc) × Qb.
Poyerekeza njira ziwirizi, zikhoza kuwoneka kuti pamtundu wofanana wothamanga, kuthamanga kwa liwiro kumapewa kutayika kwa mphamvu chifukwa cha kuwonjezeka kwa mutu woponderezedwa ndi kuwonjezeka kwa kukana kwa chitoliro pansi pa ulamuliro wa valve.Kuthamanga kwa kuthamanga kumachepetsedwa, kuthamanga kwa liwiro kumapangitsa kuti indenter ikhale yochepa kwambiri, choncho imangofunika kutayika kochepa kwambiri kuposa mphamvu ya valve kuti igwiritsidwe ntchito mokwanira.
Thehigh voltage inverteropangidwa ndi Noker Electric amagwiritsidwa ntchito kwambiri mu mafani, mapampu, malamba ndi zochitika zina, ndipo mphamvu zopulumutsa mphamvu ndizodziwikiratu, zomwe zadziwika ndi makasitomala.
