Abstract

The invention belongs to the technical field of components of diesel engines, and relates to an integrated type diesel filter. The integrated type diesel filter comprises a filter seat, the filter seat is connected with a diesel coarse filter and a diesel fine filter, a plunger type hand pump is arranged on the portion, corresponding to the position between the diesel coarse filter and the dieselfine filter, of the filter seat, wherein the plunger type hand pump comprises a plunger cavity which is arranged on the filter seat; a piston ring is arranged in the plunger cavity in a sliding mode,a piston ring sealing ring is arranged between the piston ring and the inner wall of the plunger cavity, a connecting rod is fixed on the piston ring sealing ring, and a hand pump threaded sleeve is arranged at the upper end of the plunger cavity in a threaded screwing mode; and a cover plate is connected with a pump button in a cooperating mode, the upper end of the connecting rod penetrates through the hand pump threaded sleeve to be connected with the pump button in a fastening mode, and a supporting spring is arranged in a sealing cavity formed between the piston ring and the plunger cavity. The filter integrates the hand pump, the diesel coarse filter and the diesel fine filter, so that on the premise that the function of the diesel filter is achieved, the structure is compact, the space is saved, connecting pipelines are reduced, and the pressure loss is reduced.

Description

technical field [0001] The invention belongs to the technical field of diesel engine components and relates to an integrated diesel filter. Background technique [0002] The role of the diesel filter is to filter out harmful particles in the engine fuel system and separate oil and water to protect the fuel common rail system nozzles, valve seats, etc., reduce rust, wear, and avoid clogging, thereby ensuring stable engine operation and improving reliability . The current high-performance diesel filter includes a primary diesel filter (oil-water separator) and a fine diesel filter. The primary diesel filter and the fine diesel filter are installed as two independent bodies on the engine or the frame of the vehicle. The hand pumps mostly exist in two forms, one is integrated on the diesel coarse filter, and the diaphragm type hand pump is the main one, and the other is an independent hand pump installed in series with the diesel coarse filter and the diesel fine filter. The c...
