Original abstract
This paper presents the approach for the testing of the automotive fuel pump with DC motor. Several faults such as pump jamming, incorrect soldering and/or damage to the commutator can occur due to incorrect manufacture processes. The proposed methods are based on current and magnetic field measurements and subsequent signal processing. The range checking, FFT analysis of the current ripples and change detection are combined to reach the correct and robust fault detection. During the test, the pump is optionally loaded using air suction applied to pump outlet. The implementation of developed algorithms suitable for the production line is also presented.

Tento článek popisuje nový přístup k testování a diagnostice automobilových nádržových modulů s DC motorem. Cílem je detekovat chyby, které mohli vzniknout v důsledku chyby ve výrobním procesu: zaseknutá pumpa, opačné zapojení napájecích kabelů, poškození motoru. Metody jsou založené na měření magnetického pole vně modulu a na FFT analýze zvlnění proudu. Kombinací více metod získáváme robusní postup uplatnitelný v průmyslu přímo v rámci výrobní linky.
