Background technology:
Raise with height above sea level in the highlands, atmospheric pressure descends, and oxygen content reduces; The fuel heater excess air coefficient descends simultaneously, the thermal efficiency reduces, fuel consumption increases, thermal load increases, row's temperature rise, cause to be difficult for igniting, and the afterflame ability, the thermal efficiency reduces.Therefore, the fuel heater that uses in the plains region is not suitable for the highlands, in order to solve this difficult problem, must develop the fuel heater that is suitable for the highlands characteristics.Just need lot of data to analyze and research in order to explore different altitude height to the fuel heater Effect on Performance, if site test is subjected to the influence of geographical and natural climate very big, just be difficult to set up the physical parameter and the test condition of Pass Test requirement, by contrast, in the laboratory, carry out simulation test, then than being easier to overcome above-mentioned difficulties.But the round-the-clock artificial altitude environment fuel heater simulator stand of totally enclosed type is almost still blank in China at present, also has only the U.S. and Japan that all-sealed testing laboratory is arranged abroad, but costs an arm and a leg.Chinese patent 022031561 discloses a kind of internal combustion engine performance low-pressure simulating test stage, but this testing table is not suitable for fuel heater.
Summary of the invention:
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and a kind of high height above sea level of fuel heater, the infrabar simulated experiment platform that can simulate different altitude height in the plains region is provided, carry out the simulation test of different altitude height to the fuel heater performance impact.
The technical solution of the utility model is: the high height above sea level of a kind of fuel heater, infrabar simulator stand, it is characterized in that: form by air inlet analogue means, exhaust back pressure analogue means and fuel heater, the air inlet analogue means is connected with the air intake opening of fuel heater, and the exhaust back pressure analogue means is connected with the exhausr port of fuel heater.
Described air inlet analogue means is made up of air flowmeter, intake-air throttle valve and air inlet tube of pressure-stabilizing, and air flowmeter is connected by connecting pipe with the air inlet tube of pressure-stabilizing, and intake-air throttle valve is housed on the connecting pipe, and the air inlet tube of pressure-stabilizing is connected with the air intake opening of fuel heater.

The utility model has the advantages that: because the principle of this testing table is that fuel heater gas handling system, exhaust system are transformed and sealed, utilize the simulation of vacuum pump suction realization to the plateau atmospheric environment, therefore it has small investment, simple and practical, convenient manufacturing, installation period weak point, instant effect, simulate effect is good, precision is high, also can simulate the atmospheric pressure of different altitude height, and can carry out the operating characteristic test and the fire trial of fuel heater.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
As shown in the figure: the high height above sea level of a kind of fuel heater, infrabar simulator stand, form by air inlet analogue means, exhaust back pressure analogue means and combustion having heaters.The air inlet analogue means is made up of air flowmeter 12, intake-air throttle valve 11 and air inlet tube of pressure-stabilizing 10, air flowmeter is connected by connecting pipe with the air inlet tube of pressure-stabilizing, intake-air throttle valve 11 is housed on the connecting pipe, the air inlet tube of pressure-stabilizing enters fuel heater 8 by draft tube 13, and support 9 is housed under the fuel heater.
The exhaust back pressure analogue means is made up of heat exchanger 6, exhaust tube of pressure-stabilizing 5 and water-ring vacuum pump 2.The exhaust tube of pressure-stabilizing is connected by gas outlet with water-ring vacuum pump, and exhaust shutter 3 and exhaust by-pass valve 4 are installed on gas outlet.The two ends of heat exchanger are connected with the exhausr port of fuel heater and the air intake opening of exhaust tube of pressure-stabilizing respectively, and water-ring vacuum pump is connected with a moisture trap 1.The waste gas that fuel heater is discharged enters the exhaust tube of pressure-stabilizing after cools down.This device is regulated the vacuum tightness size by exhaust shutter and exhaust by-pass valve, thus with the vacuum degree control of exhaust tube of pressure-stabilizing in the scope of required simulation.
When fuel heater is worked, in the air inlet tube of pressure-stabilizing, produce vacuum tightness by the throttling action of intake-air throttle valve, the aperture that changes intake-air throttle valve is with regard to the admission pressure in the scalable air inlet tube of pressure-stabilizing, with the atmospheric pressure of simulation different altitude height.When carrying out the fuel heater fire trial, intake-air throttle valve is closed, open the valve on the low pressure starting connecting pipe 7, by regulating the atmospheric pressure of exhaust shutter 3 and exhaust by-pass valve 4 simulation different altitude heights, promptly guaranteed the vacuum tightness in the air inlet tube of pressure-stabilizing, having guaranteed does not again have air flow in the fuel heater.In order to guarantee the degree of accuracy of measurement data, whole gas handling system, exhaust system must strict seal.
