Diesel engine fuel filter and processing technique thereof

Abstract

The invention discloses a diesel engine fuel filter. The diesel engine fuel filter comprises a protective shell, wherein a filter body is arranged on the middle portion of an inner cavity of the protective shell, and a seal end cover is mounted at the top of the upper end of the protective shell. The seal end cover is provided with fuel feed holes, and the filter body includes an upper end cover,a lower end cover and filter paper. The filter paper is fixed between the upper end cover and the lower end cover. A vertical plate is arranged on the right side of the upper end of the lower end cover, and the upper portion of the vertical plate is movably connected to the right end of the upper end cover by a hinge pin. The filter paper is internally provided with a spiral reinforcing rib. The filter paper is uniformly folded in the own circumferential direction to form a cylindrical tubular structure, and the structural strength of the filter paper is improved; fixing of the filter paper isstable, and the filter body is convenient to disassemble and install; and the spiral reinforcing rib has elasticity so that the filter paper cannot be pressed to generate deformation after being installed between the upper end cover and the lower end cover, and in this way, the filtering effect of the filter paper can be kept unaffected.

Description

technical field [0001] The invention belongs to the technical field of fuel oil filters for diesel engines, and in particular relates to a fuel oil filter for diesel engines and a processing technology thereof. Background technique [0002] The engine is one of the core components for the normal operation of a car, and is regarded as the heart of the vehicle. However, the diesel fuel filter is one of the accessories to ensure the stable and long-lasting operation of the car engine. At present, with the major automobile manufacturers With the continuous competition among the diesel engine fuel filters, they have been improved compared to before. [0003] The traditional filter element is mainly composed of upper and lower end caps, filter paper, central tube, etc. The connection between the product end caps and filter paper is not stable, and the integrity is not good, and the upper and lower end caps will exert pressure on the filter paper, causing the filter paper to deform...
