Chalk Ndi Ubwino Wa Brushless Fuel Pump Motors

Zothandizira ndi zopindulitsa za ma brushless pump motors

The commutator nthawi zambiri imayambitsa kulephera kwa mpope wamafuta. Popeza mapampu ambiri amafuta amanyowa, mafutawa amakhala ngati choziziritsa ku zida zankhondo komanso mafuta opangira maburashi ndi ma commutator. Koma mafuta a petulo sakhala oyera nthawi zonse. Mchenga wabwino ndi zinyalala mu mafuta ndi matanki amafuta zimatha kudutsa musefa ya mu thanki. Grit iyi imatha kuwononga chipwirikiti ndikufulumizitsa kuvala pamaburashi ndi ma commutator. Malo owonongeka a commutator ndi maburashi owonongeka ndizomwe zimayambitsa kulephera kwa mpope wamafuta.

Electrical and mechanical noise is also a problem. Electrical noise is generated by arcing and sparking as the brushes make and break contact on the commutator. As a precaution, most fuel pumps have capacitors and ferrite beads on the power input to limit radio frequency noise. Mechanical noise from impellers, pump gears and bearing assemblies, or cavitation from low oil levels are amplified as the oil tank acts like a big speaker to amplify even the smallest sounds.

Ma mota opopera mafuta opukutira nthawi zambiri sagwira ntchito. Ma commutator motors ndi 75-80% okha ogwira ntchito. Maginito a Ferrite sali amphamvu, zomwe zimalepheretsa kunyansidwa kwawo. Maburashi akukankhira pa commutator amapanga mphamvu zomwe pamapeto pake zimathetsa mikangano.

Mapangidwe amagetsi a brushless electronically commutated (EC) amapereka zabwino zingapo ndikuwonjezera mphamvu ya mpope. Ma motors opanda maburashi adapangidwa kuti azigwira bwino ntchito 85% mpaka 90%. Gawo lokhazikika la maginito la motor brushless limakhala pa armature, ndipo ma windings tsopano akumangiriridwa ku nyumbayo. Sikuti izi zimangochotsa kufunikira kwa maburashi ndi ma commutators, komanso zimachepetsa kwambiri kuvala kwapampu ndi kukangana komwe kumachitika chifukwa chokoka burashi. Mapampu amafuta a Brushless EC amachepetsa phokoso la RF chifukwa palibe ma arcing kuchokera kwa omwe amalumikizana ndi maburashi.

Kugwiritsa ntchito maginito osowa padziko lapansi (Neodymium), omwe ali ndi mphamvu ya maginito kwambiri kuposa ma ferrite arc maginito, amatha kupanga mphamvu zambiri kuchokera kumagetsi ang'onoang'ono ndi opepuka. Izi zikutanthawuzanso kuti zida siziyenera kuziziritsidwa. Ma windings tsopano akhoza kukhazikika pamtunda waukulu wa nyumbayo.

Kutulutsa, kuthamanga ndi kuthamanga kwa pampu yamafuta yopanda mafuta kumatha kufananizidwa kuti zikwaniritse zosowa za injini, kuchepetsa kubwereza kwamafuta mu thanki ndikusunga kutentha kwamafuta - zonse zomwe zimapangitsa kuti mpweya uzikhala wotsika.

Pali zovuta pamapampu amafuta opanda brush, komabe, imodzi yomwe imakhudza zamagetsi zomwe zimafunikira kuwongolera, kuyendetsa ndi kuyambitsa mota. Popeza ma coil a solenoid tsopano akuzungulira chida chokhazikika cha maginito, amafunika kuyatsidwa ndikuzimitsidwa ngati oyendetsa akale. Kuti izi zitheke, kugwiritsa ntchito ma semiconductors, zovuta zamagetsi, ma logic circuits, field effect transistors ndi hall effect sensors zidzalamulira ma coil omwe amayatsidwa komanso nthawi yokakamiza kuzungulira. Izi zimapangitsa kuti pakhale ndalama zambiri zopangira ma motors pump motors opanda mafuta.

Mutha kusankha mota yopopera mafuta malinga ndi zosowa zanu. Timaperekanso makasitomala ndi mayankho osiyanasiyana amafuta mpope Motors ndi Chalk galimoto, kuphatikizapo integral mpope Motors, commutators, maburashi mpweya, maginito ferrite, NdFeB, etc. Ngati simukupeza mankhwala muyenera pa webusaiti yathu, chonde tilankhule nafe. , timapereka ntchito makonda kwa makasitomala nthawi iliyonse
