Problems solved by technology

[0002] With the continuous improvement of environmental protection requirements, the application field of electric fuel pumps continues to expand, gradually extending from the field of passenger cars to the field of engineering vehicles, and the working voltage extends from 12V to 24V. However, if the 12V electric fuel pump is directly used in the 24V working environment However, there will be problems such as short life, low efficiency, and inability to adapt to harsh engineering environments. Therefore, how to provide an electric fuel pump that meets the requirements of engineering vehicles is a technical problem that needs to be solved urgently in this field.

Abstract

The invention discloses a 24V diesel fuel delivery pump which comprises a brush direct current motor and a micro pump, the brush direct current motor comprises a stator assembly, a rotor, a carbon brush assembly and a carbon brush connector, the carbon brush assembly comprises an octagonal carbon brush, and one end of the rotor is provided with a ten-groove carbon commutator; one end face of the octagonal carbon brush is arranged opposite to one end face of the ten-groove carbon commutator, the other end of the rotor is connected with the micro pump, an advanced commutation area and a delayed commutation area are formed when the octagonal carbon brush makes contact with commutator segments of the ten-groove carbon commutator, the commutation period is prolonged on the premise that the rotating speed is not changed, and the current change rate is reduced. And the risk of electric sparks caused by contact between the carbon brush and the commutator is reduced. In addition, the ten-slot carbon commutator is adopted, so that the motor can adapt to severe environments, the problem of electrocorrosion generated when the copper commutator is in contact with the carbon brush is avoided, and the service life of the product is prolonged.

Description

technical field [0001] This application relates to the technical field of oil pumps, in particular to a 24V diesel fuel delivery pump. Background technique [0002] With the continuous improvement of environmental protection requirements, the application field of electric fuel pumps continues to expand, gradually extending from the field of passenger cars to the field of engineering vehicles, and the working voltage extends from 12V to 24V. However, if the 12V electric fuel pump is directly used in the 24V working environment Therefore, how to provide an electric fuel pump that meets the requirements of engineering vehicles is a technical problem that needs to be solved urgently in this field.
