Description

A kind of mobile power vehicle generator set air inlet structure-improved

Technical field

The utility model relates to mobile power vehicle technical field, refers in particular to a kind of mobile power vehicle generator set air inlet structure-improved.

Background technique

Diesel generator uses Diesel Driven electrical power generators usually, in order to emergent use, in prior art, diesel generating set is all placed in more spacious environment usually, possess larger air output, therefore, its radiating effect is better, be unlikely to produce local temperature rise, problem falls in the power not producing whole unit.

Moving emergency supply vehicle is arranged on Trolley by diesel generating set, so that motor-driven operation, is particularly suitable for field work.But when being arranged on Trolley by diesel generating set, the form that unit design does not use according to mobile power vehicle designing, make to produce power during unit operation and fall, and the temperature rise of the diesel combustion air that has its source in of generation falling in power.

Because unit is by being assembled to Trolley chassis after transformation or partly hanging in compartment, width, the length in compartment and be highly restricted, car load height can not more than 4.2 meters, make railway carriage or compartment inner height less than 2.6 meters, width can not more than 2.5 meters, make railway carriage or compartment insied width less than 2.3 meters, the i.e. limited space in compartment, temperature rise in whole compartment machine room is caused to be difficult to control, diesel combustion air temperature is made to increase, when unit operation ambient temperature is more than 55 DEG C, ambient temperature often raises one degree Celsius, and the power of the assembling unit declines 5%.

Model utility content

The purpose of this utility model is to provide a kind of mobile power vehicle generator set air inlet structure-improved, and the combustion air temperature of generator is reduced, and then minimizing generator power falls.

For reaching above-mentioned purpose, solution of the present utility model is:

A kind of mobile power vehicle generator set air inlet structure-improved, comprises Trolley, internal-combustion engine and generator; Described internal-combustion engine and generator are arranged in Trolley compartment, internal combustion engine drive electrical power generators, internal-combustion engine arranges admission line, and admission line is communicated with the combustion chamber of internal-combustion engine, described admission line lengthens and forms lengthening section, and at the sheathed thermal insulation layer of admission line outer wall.

Further, admission line arranges air-strainer, and on internal-combustion engine, arrange turbosupercharging, the admission line between connection air-strainer and turbosupercharging lengthens and forms lengthening section.

Further, admission line arranges air-strainer, lengthen at the inlet end of air-strainer and form lengthening section, lengthening section extends to outside Trolley compartment and is connected with air.

Further, the bore of the admission line of described formation lengthening section is extremely amplified with internal-combustion engine connecting end step by step by inlet end.

After adopting such scheme, the utility model admission line lengthens and forms lengthening section, and at the sheathed thermal insulation layer of admission line outer wall, the temperature of combustion in IC engine air is cooled through longer admission line, the temperature of combustion air reduces, and then minimizing power of IC engine falls.

Fig. 2 is plan view of the present utility model.

Label declaration

Trolley 1 internal-combustion engine 2

Admission line 21 air-strainer 22

Generator 3 coupling 4

Water tank 5.

Embodiment

Below in conjunction with drawings and the specific embodiments, the utility model is described in detail.

Consult shown in Fig. 1 and Fig. 2, a kind of mobile power vehicle generator set air inlet structure-improved that the utility model discloses, comprise Trolley 1, internal-combustion engine 2 and generator 3.

Described internal-combustion engine 2 and generator 3 are arranged in Trolley 1 compartment, and described internal-combustion engine 2 is generally diesel engine, and internal-combustion engine 2 drives generator 3 to generate electricity, and usually use coupling 4 to connect and drive generator 3, as shown in Figure 1, and internal-combustion engine 2 is also connected with water tank 5.

Internal-combustion engine 2 arranges admission line 21, and admission line 21 is communicated with the combustion chamber of internal-combustion engine 2, and described admission line 21 lengthens and forms lengthening section, and at the sheathed thermal insulation layer of admission line 21 outer wall.

Can arrange air-strainer 22 on admission line 21, and on internal-combustion engine 2, arrange turbosupercharging (for indicating in figure), the admission line 21 between connection air-strainer 22 and turbosupercharging lengthens and forms lengthening section.

Simultaneously, also air-strainer 22 can be set on admission line 21, air-strainer 22 inlet end lengthen and form lengthening section, lengthening section extends to outside Trolley 1 compartment and is connected with air, the air temperature that unit is burnt and outside atmosphere temperature basically identical.

For ensureing that the air inlet of combustion air is unimpeded and air inflow is sufficient, the bore of the admission line 21 of described formation lengthening section is amplified step by step by inlet end, coefficient according to admission line 21 vapour lock amplifies step by step, namely less with atmosphere port footpath, and increases gradually with internal-combustion engine 2 connecting end.

The utility model admission line 21 lengthens and forms lengthening section, and at the sheathed thermal insulation layer of admission line 21 outer wall, the temperature of internal-combustion engine 2 combustion air is cooled through longer admission line 21, and the temperature of combustion air reduces, and then minimizing internal-combustion engine 2 power falls.

The foregoing is only preferred embodiment of the present utility model, not to the restriction of this case design, all equivalent variations done according to the design key of this case, all fall into the protection domain of this case.
