Abstract
The utility model discloses a small noise air filter for diesels, which is not only simple in structure and low in cost, but also reduces the noise when the air filter is operating. The technical characters of the air filter are that the air output pipe of the air filter reaches into the inner portion of the air filter shell from the bottom portion of the shell, a plurality of breather holes are provided on the portion of the air output pipe of the air filter where the portion reaches into the air filter shell, the filter core sleeve is arranged in the air output pipe of the air filter, the filter core shaft is pressed onto the bottom of the air filter cover and the air filter shell via a clamp device, and the air filter cover and the air output pipe of the air filter are made of engineering plastics. The air filter not only produces low noises when operation, but also reaches low weight, low cost, and convenient to batch production.
Description
Technical field
The utility model relates to the air-strainer technical field, relates in particular to a kind of air-strainer that is used for diesel engine.
Background technique
General diesel engine all is after fresh air that the external world is imported and fuel oil are mixed into oil gas, again its input engine to be fired generation power, moves reciprocatingly thereby promote piston.Can obtain clean air and keep good work status in order to ensure air inlet system and engine, avoid impurity such as aqueous vapor and dust to enter engine infringement equipment, diesel engine all is provided with air-strainer.But, existing air filtering device structure more complicated, its housing, lid and steam outlet pipe all constitute with metallic material, because the specular reflection of metallic material is stronger, thereby its noise is big, has reduced its environmental protection quality.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of low noise diesel engine air-strainer is provided, and this air-strainer is by simple structure, and lower cost has reduced the noise when air-strainer is worked.
For solving the problems of the technologies described above, the technical solution of the utility model is: the low noise diesel engine air-strainer, it comprises open-topped filter case, strainer cover with bottom opening, with the filter cleaner steam outlet pipe that can be connected with the cylinder block suction tude, described filter case is installed together the formation outside with strainer cover and is communicated with atmosphere, the air-filtering space that inner and described filter cleaner steam outlet pipe is communicated with, described air-filtering is equipped with the tubular filter core in the space, described filter cleaner steam outlet pipe inserts into the inner portion from the bottom of filter case, the tube wall of the part that stretches into filter case inside of described filter cleaner steam outlet pipe is provided with several vents, described filter core is sheathed on described filter cleaner steam outlet pipe, and described filter cleaner steam outlet pipe is fixedlyed connected with filter case; Described filter case is a plastic casing, and strainer cover is a vinyl cover, and the filter cleaner steam outlet pipe is a plastic tube; It also comprise one can be with the securing means of described filter shaft to the bottom that is squeezed in described strainer cover and filter case.
As a kind of improvement, described filter cleaner steam outlet pipe and described filter case are made as one.
After having adopted technique scheme, the beneficial effects of the utility model are: because described filter cleaner steam outlet pipe inserts into the inner portion from the bottom of filter case, the tube wall of the part that stretches into filter case inside of described filter cleaner steam outlet pipe is provided with several vents, described filter core is sheathed on described filter cleaner steam outlet pipe, described filter cleaner steam outlet pipe is fixedlyed connected with filter case, described filter shaft is provided with securing means between the bottom that is squeezed in described strainer cover and filter case, so it can guarantee that air outside enters engine cylinder after filtering, and each parts of filter cleaner tighten together, and can not produce vibration; Because the material of described filter case, strainer cover and filter cleaner steam outlet pipe is engineering plastics, so it has absorption to sound wave, has reduced the specular reflection of each parts, thereby the noise when having reduced air-strainer work.Simultaneously, working of plastics is in light weight, and cost is low, is convenient to mass production.Because described filter cleaner steam outlet pipe and described filter case are made as one, so simplified the assembly technology of filter cleaner, have improved manufacturing efficiency, and this structure realizes by Shooting Technique when also having only the employing engineering plastics.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model embodiment's a longitudinal sectional view.
Embodiment
A kind of low noise diesel engine air-strainer, as shown in drawings, it comprises the strainer cover 1 of open-topped filter case 2 and bottom opening, with filter cleaner steam outlet pipe 3 that can be connected with the cylinder block suction tude and tubular filter core 4.Described strainer cover 1, filter case 2 and tubular filter core 4 can be cylindrical shapes, also can be square tube shapes.The outside dimensions of strainer cover 1 is greater than the outside dimensions of filter case 2, so that form an air passageways that communicates with atmosphere, this structure is that those of ordinary skills are known.
Described filter cleaner steam outlet pipe 3 inserts into the inner portion from the bottom of filter case 2, the tube wall of the part that stretches into filter case inside of described filter cleaner steam outlet pipe 3 is provided with several vents, described filter core 4 is sheathed on described filter cleaner steam outlet pipe 3, a securing means is with the bottom of described filter core 4 axial compressions in described strainer cover 1 and filter case 2, described securing means comprises that one passes the bolt 5 of described strainer cover 1 and rotation set in the locking nut 6 of bolt 5 from the end cap portions of described filter cleaner steam outlet pipe 3 vertically.Like this, each parts of filter cleaner just are fixed together, and have formed that an outside is communicated with atmosphere, the inner air-filtering space that is communicated with described filter cleaner steam outlet pipe 3, and filter core 4 just is arranged in this air-filtering space.In order to guarantee that all air that enter cylinder of diesel engine from atmosphere all are through filtering, the top cover of described filter core 4 and described strainer cover 1, and the bottom of the bottom of described filter core 4 and filter case 2 is respectively equipped with seal arrangement 7.
The material of making described filter case 2, strainer cover 1 and filter cleaner steam outlet pipe 3 all adopts engineering plastics, and it has absorption to sound wave owing to engineering plastics, has reduced the specular reflection of each parts, thereby has reduced the noise when air-strainer is worked.Simultaneously, working of plastics is in light weight, and cost is low, is convenient to mass production.Described filter cleaner steam outlet pipe 3 can be divided into two systems with filter case 2 to be made, and both are fixedly connected with it then; In order to have simplified the assembly technology of filter cleaner, improved manufacturing efficiency, also can filter cleaner steam outlet pipe 3 and described filter case 2 is integrally manufactured, for Shooting Technique, by suitable mould, such structure can realize fully.
