Abstract
The utility model discloses a compressor of a noise reduction supercharger. The compressor of the noise reduction compressor comprises a compressor bypass valve and a compressor shell which are connected with each other; The compressor of the noise reduction compressor is characterized in that a noise reduction device is arranged between the compressor bypass valve and the compressor shell, wherein the noise reduction device comprises an upper perforated plate, a lower perforated plate and a noise absorbing piece; the edge of the upper perforated plate is connected with the edge of the lower perforated plate, accommodating space is formed between the upper perforated plate and the lower perforated plate, and the noise absorbing piece is arranged in the accommodating room. Under the condition that a main body structure and a principle of an existing compressor are not changed, the compressor of the noise reduction compressor additionally adds a layer of the compressor of the noise reduction compressor between the compressor by pass valve and the compressor shell of the supercharger, the noise absorbing piece in the compressor of the noise reduction compressor adopts noise absorbing fiber materials, perforated plates covers on the upper side and the lower side of the compressor of the noise reduction compressor and are used for forming an integral cushion piece structure, maintaining the shape of the noise absorbing materials, and preventing the noise absorbing material fiber to drop off to the inner portion of the compressor. Flow resistance of the noise absorbing materials is fully taken into account simultaneously, and therefore pass of air flow in the by pass valve can not be affected.
Description
Technical field
The utility model relates to motor car engine pressurized machine noise reduction process, particularly a kind of noise reduction supercharger air compressor that reduces supercharger air compressor bypass valve noise.
Background technique
Current automobile supercharged engine for protecting pressurized machine and promoting the pressurized machine dynamic response, generally can use mechanical spring diaphragm type bypass valve or electronic bypass valve at gas compressor.Thereby when automobile because when brake, deceleration engine throttled back; the air inlet pipeline internal pressure sharply raise when pressurized machine was understood owing to effect of inertia; this moment, the gas compressor bypass valve was opened; between blower outlet and entrance, form inner cycle channel; reducing the air inlet pipeline internal pressure avoids pressurized machine to enter surge area; keep the high rotating speed of supercharger impeller simultaneously, to reach the effect of protecting pressurized machine and promoting the pressurized machine dynamic response.
When but mechanical bypass valve was opened, the air-flow path that forms between valve block and compressor housings was very narrow and small, when gas is flowed through herein by blower outlet, the gas communication cross section diminishes, gas flow rate increases, and produces a large amount of turbulent flows when gas enters the gas compressor ingress, thereby produces gas noise.This noise anxious add at the automobile of driving at low speed, the easiest of the perception of people's ear institute during anxious the deceleration.Adopt sound absorption structure to reduce this noise like in the airflow path design of present most producer before and after the pressurized machine, the increase that this will the noise cost, and do not utilize complete vehicle structure to arrange.
The model utility content
The purpose of this utility model is to provide a kind of noise reduction supercharger air compressor of the noise that produces when reducing the work of gas compressor machinery bypass valve.
For solving the problems of the technologies described above, the utility model noise reduction supercharger air compressor comprises compressor housings and is installed in gas compressor bypass valve on the described compressor housings; It is characterized in that be provided with a denoising device between described gas compressor bypass valve and described compressor housings, described denoising device comprises: go up perforated plate; Following perforated plate, the described edge of going up perforated plate is connected with the described edge of perforated plate down, formation one containing space between perforated plate and the described following perforated plate on described; And sound absorption plate, described sound absorption plate is arranged in the described containing space.The size of described containing space and the size of described sound absorption plate are complementary.The material of described sound absorption plate is the sound absorption fiber.
The utility model noise reduction supercharger air compressor is by under the situation that does not change existing intensifier body structure and principle, by extra one deck noise reduction supercharger air compressor that increases between gas compressor bypass valve and compressor casing of pressurizer body, sound absorption plate in the noise reduction supercharger air compressor is the sound absorption lamination coating, both sides cover perforated plate (punching rate of perforated plate is decided according to dissimilar pressurized machines) up and down, in order to form whole gasket construction, keep the sound-absorbing material shape, and prevent that the sound-absorbing material fibre shedding from entering gas compressor inside, taken into full account the flow resistance of sound-absorbing material simultaneously, the air-flow that can not have influence on bypass valve passes through.
The utility model noise reduction supercharger air compressor structure is very simple, do not change the design of former pressurized machine and bypass valve, only need are made the suitable sound-absorption pad according to former bypass valve sealing surface shape, it are installed between gas compressor bypass valve and the compressor casing of pressurizer body get final product.

Embodiment
Below in conjunction with accompanying drawing the utility model noise reduction supercharger air compressor is described in further detail.
As Fig. 1, shown in Figure 2, as shown in Figure 1, the utility model noise reduction supercharger air compressor, comprise compressor housings 2 and be installed in gas compressor bypass valve 1 on the described compressor housings 2, between described gas compressor bypass valve 1 and described compressor housings 2, be provided with a denoising device 3, described denoising device 3 comprises: circular last perforated plate 4 reaches perforated plate 5 down, the edge of last perforated plate 4 is connected with the edge of following perforated plate 5, between last perforated plate 4 and following perforated plate 5, form a containing space, material just is arranged in the containing space for the sound absorption plate 6 of sound absorption fiber, and the size of the size of containing space and sound absorption plate 6 is complementary.
The utility model noise reduction supercharger air compressor is by under the situation that does not change existing intensifier body structure and principle, by the extra one deck denoising device 3 that increases between gas compressor bypass valve 1 and compressor housings 2, sound absorption plate in the denoising device 3 is the sound absorption lamination coating, both sides cover perforated plate (punching rate of perforated plate is decided according to dissimilar pressurized machines) up and down, in order to form whole gasket construction, keep the sound-absorbing material shape, and prevent that the sound-absorbing material fibre shedding from entering gas compressor inside, taken into full account the flow resistance of sound-absorbing material simultaneously, the air-flow that can not have influence on bypass valve passes through.
The utility model noise reduction supercharger air compressor structure is very simple, do not change the design of former pressurized machine and bypass valve, only need are made the suitable sound-absorption pad according to former bypass valve sealing surface shape, it are installed between gas compressor bypass valve and the compressor casing of pressurizer body get final product.
Below the preferred embodiment of the utility model having been created specifies, but the utility model is not limited to embodiment, those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite of the utility model creative spirit, the modification that these are equal to or replacement all are included in the application's the scope.
