Abstract
The utility model discloses a V-shaped engine supercharger device which comprises two exhaust gas turbochargers, a lubricating oil return pipe, an exhaust gas exhaust pipe and a support frame, wherein the exhaust gas turbochargers are connected with the lubricating oil return pipe through a first corrugated pipe flange. According the V-shaped engine supercharging device, the exhaust gas turbochargers and the lubricating oil return pipe as well as the exhaust gas turbochargers and the exhaust gas exhaust pipe are connected through corrugated pipe flanges; the corrugated pipe flanges can adsorb the heat displacement generated by parts due to temperature variation and can also adsorb the vibration displacement, so as to prevent a connecting part from damage due to thermal expansion and cold contraction or vibration, enable the structure of the supercharger device to be more stable and avoid the occurrence of oil leakage or gas leakage; meanwhile, the assembling is easier by adopting the connection of the corrugated pipe flanges; and a first framework of the support frame of the supercharger device simultaneously supports the two turbochargers, bears the balance moments and is better in stability.
Description
Technical field
The utility model relates to a kind of enginer supercharging device.
Background technique
V-type diesel adopts the mode air inlet of two exhaust-gas turbocharger superchargings, and the turbo charging installation structure comprises: exhaust-gas turbocharger, lubricating oil return pipe, waste gas exhaust pipe, pressurized air outlet pipe and support.In the existing technology: two exhaust-gas turbochargers be adopt respectively two independently support be fixed on the motor; Exhaust-gas turbocharger has only a waste gas inlet, the supercharging of monopulse formula; Between exhaust-gas turbocharger and the lubricating oil return pipe, between exhaust-gas turbocharger and the waste gas exhaust pipe and all be rigidly connected between exhaust-gas turbocharger and the pressurized air outlet pipe.There is following shortcoming in turbo charging installation of the prior art:
1, independent rack is not supported on the center of gravity vertical line of turbosupercharger; The non-equilibrium moment that it wants stressed turbosupercharger to apply, stress-bearing capability is relatively poor, and pressurized machine is all bigger with the vibrations of motor when working; Therefore the connecting bolt on the independent rack damages easily, and structure stability is relatively poor.
2, have only a waste gas inlet, the supercharging of monopulse formula, the exhaust energy utilization ratio is lower.
3, between exhaust-gas turbocharger and the lubricating oil return pipe, between exhaust-gas turbocharger and the waste gas exhaust pipe and all be rigidly connected between exhaust-gas turbocharger and the pressurized air outlet pipe; The vibrations displacement that the thermal walking that produces in the time of can not eliminating part and be heated and vibrations cause; Joint damages easily, and structure stability is poor.
Therefore need improve exhaust gas turbocharge device of the prior art, to improve its structure stability and exhaust energy utilization ratio.
The model utility content
In view of this, the purpose of the utility model provides a kind of V-type engine supercharger arrangement, and it has, and structure stability is good, exhaust energy utilization ratio advantages of higher.
The utility model V-type engine supercharger arrangement comprises two exhaust-gas turbochargers, lubricating oil return pipe, waste gas exhaust pipe and support, and said exhaust-gas turbocharger is connected through the first bellows flange with the lubricating oil return pipe.
Further, the Waste gas outlet of said two exhaust-gas turbochargers is connected with the 3rd bellows flange through the second bellows flange respectively with waste gas exhaust pipe;
Further, said support comprises first framework that is supported in two exhaust-gas turbochargers below simultaneously and is fixed on first framework and is supported in second framework of waste gas exhaust pipe below;
Further, said two exhaust-gas turbochargers are provided with two waste gas inlets.
The beneficial effect of the utility model: the utility model V-type engine supercharger arrangement; Exhaust-gas turbocharger all is connected through the bellows flange with waste gas exhaust pipe with lubricating oil return pipe and exhaust-gas turbocharger; The bellows flange can absorb thermal walking that part produces because of temperature variation, can also the absorbing vibration displacement; Thereby can guarantee that connection part can not damage because of expanding with heat and contract with cold or shaking, make the supercharging device structure more stable, and can avoid the gas leak of the oil leakage situation to take place; Adopting the bellows flange to connect simultaneously also can make assembling easier; First framework of the support of this supercharger arrangement supports two turbosupercharger simultaneously, and first framework bears trimming moment, and stability is better.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is the plan view of the utility model V-type engine supercharger arrangement;
Fig. 2 is the left view of Fig. 1.
Embodiment
Fig. 1 is the plan view of the utility model V-type engine supercharger arrangement; Fig. 2 is the left view of Fig. 1.
As shown in the figure, present embodiment V-type engine supercharger arrangement comprises two exhaust-gas turbochargers 1, lubricating oil return pipe 2, waste gas exhaust pipe 3 and support, and said exhaust-gas turbocharger 1 is connected through the first bellows flange 4 with lubricating oil return pipe 2.The bellows flange can absorb thermal walking that part produces because of temperature variation, can also the absorbing vibration displacement, thereby can guarantee that connection part can not damage because of expanding with heat and contract with cold or shake, make the supercharging device structure more stable, and can avoid the generation of leakage of oil situation; Adopting the bellows flange to connect simultaneously also can make assembling easier.
As the improvement to this embodiment, the Waste gas outlet of said two exhaust-gas turbochargers 1 is connected with the 3rd bellows flange 6 through the second bellows flange 5 respectively with waste gas exhaust pipe 3.Can avoid joint to cause damage because of thermal distortion or vibrations, structure is firm, can avoid the gas leakage situation to take place.
As the improvement to this embodiment, said support comprises first framework 7 that is supported in two exhaust-gas turbochargers below simultaneously and is fixed on first framework 7 and is supported in second framework 8 of waste gas exhaust pipe 3 belows; It is trimming moment that first framework bears the moment that exhaust-gas turbocharger applies, and stability is better.
As improvement to this embodiment; Said two exhaust-gas turbochargers 1 are provided with two waste gas inlet 1a, and it can be connected with two exhaust manifolds of motor same column cylinder body respectively, and intake resistance is littler; Exhaust energy loses still less in flow process, can improve the pressurized machine boosting capability.
Explanation is at last; Above embodiment is only unrestricted in order to the technological scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technological scheme of the utility model; And not breaking away from the aim and the scope of the utility model technological scheme, it all should be encompassed in the middle of the claim scope of the utility model.
