Abstract
The utility model discloses an engine altitude environment storehouse, comprising a storehouse provided with a port at one side and an airtight steel shell and a heat insulation inner film, wherein the space between the steel shell and the heat insulation inner film forms the thermostat layer. The airtight steel shell is formed by alignment welding the H shaped steel. The engine altitude environment storehouse can simulate the altitude environment to test the stand of the engine.
Description
Technical field
The utility model relates to the engine performance measuring test cabin, and particularly a kind of test bay that is implemented in is simulated altitude environment is carried out bench test to engine engine altitude environment storehouse.
Background technology
Be used to finish the test of following laws and regulations requirement in the engine altitude environment test cabin: by ESC, ETC, the ELR operating mode in Europe (Europe II, Europe III, Europe IV); Stable state 13 operating modes of ECE R49 regulation; The visible pollutant test of ECER22 circulation; Test circulation, U.S. EPA heavy truck transient condition, the Japanese 13 operating mode standards of ISO8178.4 regulation are carried out dynamic property, economy, emission behavior, fuel oil and the lubricating oil of engine to the influence of car load and engine performance, the comparison test that the catalytic converter product is selected for use etc.
Because it is higher that car load carries out the three high costs of testing at present, expend more manpower and materials again, testing crew will bear the test of high and low temperature environment and high altitude environment, also cause simultaneously automobile production enterprise substantial contribution, human and material resources cost waste, the construction cycle of car load is also long, after the height above sea level storehouse warehouse box hat of prior art adopts angle steel and joist steel splicing mostly, again in the form of inboard welding steel, workman's workload is big, the consumption of steel is many, also causes the waste of bigger manpower and materials.So setting up the engine height above sea level storehouse that can finish engine and car load altitude environment simulation test can not adapt to the problem of working under the altitude environment and necessitate to solve numerous vehicles.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of engine altitude environment storehouse, to satisfy the requirement of heterogeneity engine from different purposes.
For achieving the above object, the engine altitude environment storehouse that the utility model provides comprises a warehouse, and described warehouse one side has hatch door, it is characterized in that, described warehouse comprises the outer and heat insulation nexine of an airtight box hat, and the space between described box hat skin and the heat insulation nexine constitutes thermostat layer.
Above-mentioned engine altitude environment storehouse is characterized in that, described airtight box hat adopts H shaped steel to arrange and is welded.
Above-mentioned engine altitude environment storehouse is characterized in that, a bitubular rotary drum also is set in the described warehouse.
Above-mentioned engine altitude environment storehouse is characterized in that, it is one stepped that the bottom of described warehouse is.
Compared with prior art, engine altitude environment of the present utility model storehouse, can be implemented in test bay simulation altitude environment engine is carried out bench test, can reach temperature, humidity and the pressure that configures fast in the environment storehouse, can satisfy engine development testing requirements of different nature from different purposes.The box hat that adopts H shaped steel to be welded is not only saved the consumption of steel, has alleviated the weight of box hat, and has reduced the workload of welding, and box hat intensity is also greater than in the past height above sea level storehouse box hat.Application of the present utility model not only for enterprise, for country has saved substantial contribution, man power and material, more the development of engine and car load provides condition more easily under the altitude environment, has effectively reduced the construction cycle.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model being done detailed description, with purpose, effect and the technical scheme of further understanding the utility model, but is not the protection domain that is used for limiting the utility model claims.
With reference to figure 1, Fig. 2 and Fig. 3, engine altitude environment storehouse of the present utility model comprises a warehouse, one side of warehouse has hatch door 4, this warehouse comprises an airtight box hat layer 1 and a heat insulation nexine 2, be full of dry air in the gap between airtight box hat layer 1 and the heat insulation nexine 2 and constitute heat-insulation layer 3, dynamometer machine 5 and other utility appliance are arranged in the outer heat-insulation layer 3 of height above sea level storehouse box hat layer inner insulating layer.Heat-insulation layer 3 guarantees environment constant temperature by conditioner, avoids the influence of high low temperature to electric equipment.Warehouse disposed outside refrigeration unit, pump group, tail gas pump drainage negative-pressure air fan etc., the bottom of warehouse is provided with a ladder, be fixed on the ground, in the height above sea level storehouse, be provided with a simple and easy bitubular rotary drum 6, automobile enters warehouse from hatch door 4 and drives bitubular rotary drum and carry out simulation test, the box hat in height above sea level storehouse adopts H shaped steel to arrange the mode of welding, steel material is identical, version is unified, not only save the consumption of steel, alleviated the weight of box hat, and reduced the workload of welding, box hat intensity is also greater than in the past height above sea level storehouse box hat.
The outer refrigeration unit of warehouse uses environment friendly refrigerating fluid R404A.Its advantage is high rule, stable performance, and environmental protection organization accepts by the whole world.Refrigeration unit is made up of semi-enclosed screw compressor.Control new wind pressure, exhaust air suction and scavenging with a rotator type blower fan.A high-pressure fan is installed in the fresh wind tube.When variable valve suppresses the supply of new wind, just produced negative pressure in the storehouse.Harmful gas monitoring system, monitoring CO, HC and NO2, sound and light alarm also are installed in the height above sea level storehouse.Height above sea level storehouse system possesses the self-protection function, is equipped with apparatus for protecting power supply and when sudden power computer equipment and data is shielded.
Following three kinds of different test methods can be realized in engine altitude environment of the present utility model storehouse, have satisfied engine development testing requirements of different nature on the different purposes:
(1) the various atmospheric pressures of simulation, temperature and humidity environment in the storehouse, engine is got gas in the storehouse, the identical atmospheric pressure conditions of engine exhaust system simulation simultaneously
(2) do not simulate atmospheric environment in the storehouse, have only the engine inlet and exhaust system to simulate various atmospheric pressures, temperature and humidity environment.
(3) the certain atmospheric pressure of simulation, temperature and humidity environment in the storehouse, atmospheric pressure and different intake air temperature environment that the engine aspirating system simulation is identical, the identical atmospheric pressure conditions of engine exhaust system simulation simultaneously.
Though the utility model discloses as above with a preferred embodiment; right its is not in order to limit the utility model; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the utility model claims.
