Lisebelisoa le Melemo ea Brushless Fuel Pump Motors

Lisebelisoa le melemo ea li-motors tsa pompo tsa peterole tse se nang mafura

Hangata motlakase ke sesosa se ka sehloohong sa ho hlōleha ha pompo ea mafura. Kaha boholo ba lipompo tsa peterole li kolobile, peterole e sebetsa joalo ka sepholi bakeng sa lihlomo le setlolo bakeng sa borashe le lisebelisoa. Empa peterole ha se kamehla e hloekileng. Lehlabathe le litšila tse ka har'a peterole le litanka tsa mafura li ka feta sefeneng se ka har'a tanka. Grit ena e ka baka tšenyo 'me ea potlakisa ho roaloa ha borashe le bokaholimo ba baeti. Libaka tse senyehileng tsa lipalangoang le borashe bo senyehileng ke tsona lisosa tse ka sehloohong tsa ho hloleha ha pompo ea mafura.

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.

Li-motors tsa pompo ea peterole tse hloekisitsoeng hangata ha li sebetse hantle. Li-motor tsa likoloi li sebetsa hantle ka 75-80%. Limanete tsa Ferrite ha li matla joalo ka ha li fokotsa ho nyenyefatsa ha tsona. Li-brushes tse sutumetsang mochining oa likoloi li theha matla a felisang likhohlano.

Moralo oa enjene ea brushless electronically commutated (EC) o fana ka melemo e mengata le ho eketsa katleho ea pompo. Li-motor tse se nang brush li etselitsoe ho sebetsa hantle ka 85% ho isa ho 90%. Karolo ea makenete e sa feleng ea enjene ea brushless e lutse holim'a armature, 'me li-winding li se li hokahantsoe le ntlo.

There are downsides to brushless fuel pumps, though, one of which involves the electronics needed to control, operate and start the motor. Since the solenoid coils now surround a permanent magnet armature, they need to be switched on and off like the old commutators. To achieve this, the use of semiconductors, complex electronics, logic circuits, field effect transistors and hall effect sensors will control which coils are turned on and when to force rotation. This results in higher production costs for brushless fuel pump motors.
