Abahlinzeki bedivayisi yempendulo yamandla bakukhumbuza ukuthi iziguquli zemvamisa zisetshenziswa kakhulu ekukhiqizweni kokulawulwa kwezimboni. Lesi isisetshenziswa sikagesi esisebenzisa isekethe ehlukile ukuguqula ugesi ongu-50HZ ube ugesi we-AC onefrikhwensi elungisekayo kanye ne-voltage, ukuze ushayele amamotho e-AC asynchronous ezigaba ezintathu. Njengesiguquli sefrikhwensi esakhiwe ubuchwepheshe be-microelectronics namamojula we-electronics yamandla, ukusebenza kwawo kukagesi kuthintwa kakhulu izinga lokushisa lemvelo, umswakama womoya, ukudlidliza komshini, uthuli, namagesi abolayo ekusebenzeni okungokoqobo.
Ukwehluleka kwesikhathi eside ukugcina isiguquli sefrikhwensi kungaholela ekwehleni kokusebenza kahle nokuphepha. Ikakhulukazi uthuli nomoya onomswakama, uma kungasuswanga ngesikhathi, kungabangela ukushisa okukhulu kwe-inverter kanye nezingxenye ze-elekthronikhi zangaphakathi, okuholela ekungasebenzi kahle noma ukunciphisa impilo yesevisi ye-inverter. Ngakho-ke, kuyadingeka ukwenza ukugcinwa kwansuku zonke nokujwayelekile ku-converter frequency.
Izinto zokuhlola zansuku zonke zokuguqula imvamisa:
(1) Ukuthi noma kukhona noma yiziphi izinguquko ezingavamile emsindweni ngesikhathi sokusebenza kwenjini, okuhlanganisa noma kukhona ukudlidliza ngesikhathi sokusebenza kwenjini.
(2) Ingabe kube khona ushintsho endaweni yokufaka isiguquli sefrikhwensi. Kungakhathaliseki ukuthi izinga lokushisa le-ambient lijwayelekile noma cha, izinga lokushisa elisebenzayo lesiguquli semvamisa livamise ukuba phakathi kwebanga elingu -10 ℃ ukuya ku+40 ℃, okungcono licishe libe ngu-25 ℃.
(3) Ukuthi ingabe ifeni epholile yesiguquli sefrikhwensi isebenza kahle yini, okuhlanganisa noma ngabe ishaneli yokupholisa yesiguquli sefrikhwensi ayiphazamiseki yini. Ingabe idatha yokuphumayo yamanje, i-voltage, imvamisa, njll. eboniswa kuphaneli yesibonisi yesiguquli sefrikhwensi evamile. Ukuthi izinhlamvu ezikuphaneli yesibonisi zicacile yini nokuthi ama-stroke awekho yini.
(4) Ingabe isiguquli semvamisa sishisa ngokweqile. Ithemometha ye-infrared ingasetshenziswa ukuthola ukuthi usinki wokushisa wesiguquli sefrikhwensi ushise ngokweqile noma unephunga. Hlola ukuthi akhona yini ama-alamu anephutha ngesikhathi sokusebenza kwesiguquli sefrikhwensi.
(5) Hlanza njalo isikrini sokuhlunga somgudu wokungenisa umoya ngaphakathi kwekhabhinethi yokulawula ugesi. Hlala njalo ugcine ikhabethe lokulawula kanye nesiguquli sefrikhwensi sisesimweni esihlanzekile. Khipha kahle uthuli olungaphezulu kusiguquli sefrikhwensi ukuze uvimbele uthuli olunqwabelene ukuthi lungene kusiguquli sefrikhwensi. Ikakhulukazi uthuli lwensimbi. Susa ngempumelelo amabala kawoyela kufeni epholile yesiguquli sefrikhwensi.
(6) Sebenzisa ishejuli yokulungisa yonyaka ukuze uvule isiguquli sefrikhwensi futhi ugxile ekuhlanzeni izingxenye zangaphakathi ezingabonakali phakathi nemisebenzi evamile yansuku zonke. Hlanza ibhodi lesifunda lesiguquli se-frequency kanye nemojula yalo yangaphakathi yokulungisa, imojula ye-IGBT, i-DC filter electrolytic capacitor, i-reactor yokufaka/yokukhiphayo, njll. Sebenzisa ibhulashi noma isicoci se-vacuum. Shintshanisa izingxenye ze-elekthronikhi ezingafanelekile (qaphela: i-capacitor yokuhlunga yangaphakathi ye-converter frequency ngokuvamile idinga ukushintshwa njalo eminyakeni emi-4-5).
(7) Hlola isiphephetha-moya sokupholisa: Njengoba isiphephetha-moya sokupholisa sidinga ukusebenza okuqhubekayo kwesikhathi eside, siyingxenye ethambekele ekulimaleni. Ukuphila kwayo kunqunyelwe ama-bearings (kuyi-axial fan). Ngokuvumelana ne-frequency converter, abalandeli noma ama-fan bearings ngokuvamile ashintshwa njalo eminyakeni engu-2-3.
