1.Frequency kutembenuka mphamvu zopulumutsa

Kupulumutsa mphamvu kwa ma frequency converter kumawonetsedwa makamaka pakugwiritsa ntchito fan ndi pampu yamadzi.Pambuyo pakuwongolera kuthamanga kwa ma frequency osinthika kumatengera katundu wa fani ndi mpope, mphamvu yopulumutsa mphamvu ndi 20% ~ 60%, chifukwa mphamvu yeniyeni yogwiritsira ntchito mafani ndi mapampu amayenderana ndi mphamvu yachitatu ya liwiro.Pamene pafupifupi otaya chofunika ndi owerenga ndi yaing'ono, mafani ndi mapampu amatengera pafupipafupi kutembenuka liwiro malamulo kuchepetsa liwiro lawo, ndi mphamvu yopulumutsa mphamvu ndi zoonekeratu.Ngakhale mafani achikhalidwe ndi mapampu amagwiritsa ntchito ma baffles ndi mavavu kuti azitha kuyendetsa bwino, kuthamanga kwagalimoto sikusintha, komanso kugwiritsa ntchito mphamvu kumasintha pang'ono.Malinga ndi ziwerengero, kugwiritsa ntchito mphamvu kwa ma fan ndi ma pump motors kumatenga 31% yamagetsi adziko lonse komanso 50% yamagetsi ogwiritsidwa ntchito m'mafakitale.Ndikofunikira kwambiri kugwiritsa ntchito pafupipafupi kutembenuka liwiro lamulo chipangizo pa katundu wotere.Pakalipano, ntchito zomwe zikuyenda bwino kwambiri ndikuphatikiza madzi othamanga nthawi zonse, kuwongolera kuthamanga kwa mafani osiyanasiyana, ma air conditioners apakati ndi mapampu a hydraulic.

2.Frequency kutembenuka mphamvu kupulumutsa

Kupulumutsa mphamvu kwa ma frequency converter kumawonetsedwa makamaka pakugwiritsa ntchito fan ndi pampu yamadzi.Pambuyo pakuwongolera kuthamanga kwa ma frequency osinthika kumatengera katundu wa fani ndi mpope, mphamvu yopulumutsa mphamvu ndi 20% ~ 60%, chifukwa mphamvu yeniyeni yogwiritsira ntchito mafani ndi mapampu amayenderana ndi mphamvu yachitatu ya liwiro.Pamene pafupifupi otaya chofunika ndi owerenga ndi yaing'ono, mafani ndi mapampu amatengera pafupipafupi kutembenuka liwiro malamulo kuchepetsa liwiro lawo, ndi mphamvu yopulumutsa mphamvu ndi zoonekeratu.Ngakhale mafani achikhalidwe ndi mapampu amagwiritsa ntchito ma baffles ndi mavavu kuti azitha kuyendetsa bwino, kuthamanga kwagalimoto sikusintha, komanso kugwiritsa ntchito mphamvu kumasintha pang'ono.Malinga ndi ziwerengero, kugwiritsa ntchito mphamvu kwa ma fan ndi ma pump motors kumatenga 31% yamagetsi adziko lonse komanso 50% yamagetsi ogwiritsidwa ntchito m'mafakitale.Ndikofunikira kwambiri kugwiritsa ntchito pafupipafupi kutembenuka liwiro lamulo chipangizo pa katundu wotere.Pakalipano, ntchito zomwe zikuyenda bwino kwambiri ndikuphatikiza madzi othamanga nthawi zonse, kuwongolera kuthamanga kwa mafani osiyanasiyana, ma air conditioners apakati ndi mapampu a hydraulic.

3.Kugwiritsa ntchito pakuwongolera msinkhu wa ndondomeko ndi khalidwe la mankhwala

Makina osinthira pafupipafupi amathanso kugwiritsidwa ntchito kwambiri m'magawo osiyanasiyana owongolera zida zamakina monga kutumiza, kukweza, kutulutsa ndi zida zamakina.Ikhoza kupititsa patsogolo msinkhu wa ndondomeko ndi khalidwe lazogulitsa, kuchepetsa mphamvu ndi phokoso la zipangizo, ndikuwonjezera moyo wautumiki wa zida.Pambuyo potengera kuwongolera pafupipafupi kutembenuka kwa liwiro, dongosolo lamakina limakhala losavuta, ndipo ntchito ndi kuwongolera ndizosavuta.Ena amatha kusintha ndondomeko yoyambirira, motero kuwongolera ntchito ya zida zonse.Mwachitsanzo, pamakina a nsalu ndi ma size omwe amagwiritsidwa ntchito m'mafakitale ambiri, kutentha mkati mwa makinawo kumasinthidwa ndikusintha kuchuluka kwa mpweya wotentha.Fani yozungulira nthawi zambiri imagwiritsidwa ntchito potumiza mpweya wotentha.Popeza kuthamanga kwa fan kumakhala kosalekeza, kuchuluka kwa mpweya wotentha kumangosinthidwa ndi damper.Ngati damper ikulephera kusintha kapena kusinthidwa molakwika, makina omangira amatha kutaya mphamvu, motero amakhudza ubwino wa zinthu zomalizidwa.Kuthamanga kozungulira kumayambira pa liwiro lalikulu, ndipo kuvala pakati pa lamba woyendetsa galimoto ndi kunyamula kumakhala koopsa kwambiri, kumapangitsa lamba woyendetsa galimoto kukhala wodyedwa.Pambuyo pafupipafupi kutembenuka liwiro malamulo anatengera, malamulo kutentha akhoza anazindikira ndi pafupipafupi Converter basi kusintha liwiro zimakupiza, amene amathetsa vuto mankhwala khalidwe.Kuphatikiza apo, chosinthira pafupipafupi chimatha kuyambitsa fan pafupipafupi komanso kuthamanga kwambiri, kuchepetsa kuvala pakati pa lamba woyendetsa ndi kunyamula, kuwonjezera moyo wautumiki wa zida, ndikupulumutsa mphamvu ndi 40%.

4.Kuzindikira kwa motor soft start

Kuyamba movutikira kwa injini sikungoyambitsa vuto lalikulu pa gridi yamagetsi, komanso kumafunika mphamvu ya gridi yochulukirapo.Kugwedezeka kwakukulu komwe kumachitika poyambira kumayambitsa kuwonongeka kwakukulu kwa ma baffles ndi ma valve, ndipo kudzakhala kowononga kwambiri moyo wautumiki wa zida ndi mapaipi.Pambuyo pogwiritsira ntchito inverter, ntchito yoyambira yofewa ya inverter idzapanga kusintha kwaposachedwa kuchokera ku ziro, ndipo mtengo wamtengo wapatali sudzapitirira oveteredwa panopa, kuchepetsa zotsatira za gululi mphamvu ndi zofunika mphamvu magetsi, kuwonjezera utumiki. moyo wa zida ndi mavavu, komanso kupulumutsa mtengo kukonza zipangizo
