Abstract
The utility model discloses a thermal insulating cover for turbochargers, which comprises cover casings corresponding to the shape of a turbine casing of the turbocharger, wherein the cover casings comprise a front cover casing and a rear cover casing which are fixedly connected; the front cover casing is provided with a fixing part for fixing the cover casings on the turbocharger; the inner walls of the cover casings are provided with high temperature resistant thermal insulating layers. The utility model can effectively implement protection and thermal insulation to the turbine casing of the turbocharger, and causes the structure of the thermal insulating cover for turbochargers to be compact and simple.
Description
Technical field
The utility model relates to a kind of protective equipment, especially relates to the turbosupercharger thermal shield on a kind of turbosupercharger that is used for motor.
Background technique
Now, the general exhaust-gas turbocharger that adopts on motor, the combustion gas of the High Temperature High Pressure of promptly discharging from outlet pipe promotes the turbine rotation on the pressurized machine, turbine drives gas compressor by jack shaft and rotates, the air of gas compressor compression inspiration, in the suction tude of motor, produce higher suction pressure, reaching the purpose of many air inlets, thereby improve the performance of motor.But in supercharged engine work, the combustion gas of High Temperature High Pressure promotes turbine rotation, can be heated to very high temperature to turbine case, this just exists certain danger, scald the operator easily, and a large amount of heats can be distributed to machine room in the turbine case surface of high temperature, the temperature of machine room is raise, influence operating environment.And the current more employed in actual applications protective gear that is used for the turbine case of high temperature, can not be perfect address these problems.
Summary of the invention
The technical problems to be solved in the utility model has provided a kind of can be effectively the turbine case of high temperature the protection and heat insulation turbosupercharger thermal shield.
For solving the problems of the technologies described above, the technical solution of the utility model is: the turbosupercharger thermal shield, comprise and the corresponding case of the shape of pressurized machine volute, described case comprises fixedly connected front end-cover and rear casing, and described front end-cover is provided with the fixing part that described case can be fixed on the turbosupercharger; But the inwall of described case is fixed with the thermostable heat insulation layer.
As a kind of optimal way, be provided with stiffening plate between described fixing part and the front end-cover.
As another kind of optimal way, described thermal-protective coating is the silicone rubber thermal-protective coating.
As another kind of optimal way, described thermal-protective coating is that thickness is the lamelliform of 0.4～0.8mm.Adopt the turbosupercharger thermal shield of said structure, but owing to being to have adopted the cover body structure of an integral body and being on the inwall of case, to be provided with the thermostable heat insulation layer, therefore its heat influence to external world that not only can prevent from the booster turbine to be given out, the surface temperature that makes this turbosupercharger thermal shield is fully in the scope that human body can bear, and this turbosupercharger thermal shield is the housing designs according to booster turbine fully, when playing effect of heat insulation, can also make can be too not lengthy and tedious because of the increase of component on the motor.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Fig. 1 is the structural representation of turbosupercharger thermal shield of the present utility model;
Fig. 2 is the right elevation of Fig. 1.
Embodiment
See figures.1.and.2, a kind of turbosupercharger thermal shield of the present utility model is: the turbosupercharger thermal shield, comprise and the corresponding case 4 of the shape of pressurized machine volute, case 4 comprises fixedly connected front end-cover 41 and rear casing 42, as the mode that can adopt welding front end-cover 41 and rear casing 42 is fixed together closely.On front end-cover 41, be provided with the fixing part 2 that case 4 can be fixed on the turbosupercharger, can adopt on fixing part 2 and be provided with open-work, and adopt this simple means of fixation of bolt, so that the installation and removal of this turbosupercharger thermal shield become convenient.In order further to strengthen the intensity of this turbosupercharger thermal shield, can between fixing part 2 and front end-cover 41, be provided with stiffening plate 3; But the inwall at case 4 is fixed with thermostable heat insulation layer 5, and, the thermal-protective coating that this thermal-protective coating 5 is made for silicone rubber material, to play enough effect of heat insulation, and this thermal-protective coating 5 can be the lamelliform that thickness is 0.4～0.8mm, make its play heat insulation in, also reduce the weight and the cost of this turbosupercharger thermal shield as much as possible.And, when making this turbosupercharger thermal shield, it is that the steel plate of 1mm draws and is made that its front end-cover 41 and rear casing 42 can adopt thickness, and, adopt than the long radius round-corner transition bending place of rear casing 42, thereby make that the structure of this turbosupercharger thermal shield is compact more and succinct.
Claims (4)
1, turbosupercharger thermal shield, comprise and the corresponding case of the shape of pressurized machine volute (4), it is characterized in that: described case (4) comprises fixedly connected front end-cover (41) and rear casing (42), and described front end-cover (41) is provided with the fixing part (2) that described case (4) can be fixed on the turbosupercharger; Described case (4) but inwall be fixed with thermostable heat insulation layer (5).
