Description
Technical field
The present invention relates to a kind of cooler for recycled exhaust gas performance comprehensive testing device, belong to field of mechanical technique.
Background technology
At present, EGR refers to gas recirculation system, and the performance verification of cooler for recycled exhaust gas typically has two kinds of approach: one is made by engine pedestal tests, and another kind of method is to use natural gas as the assay device of fuel.Both approaches cannot obtain the data that cooler for recycled exhaust gas is optimized design, such as electromotor and flow through the exhaust flow of cooler for recycled exhaust gas, pressure, temperature under different operating modes；All cannot learn in data such as the flow of each operating mode dirty supercooling liquid, pressure, temperature, the cycle that additionally these experimental provisions need is long, costly simultaneously.
Summary of the invention
The present invention is directed to the problems referred to above, it is provided that a kind of cooler for recycled exhaust gas performance comprehensive testing device, cooler for recycled exhaust gas performance can be tested by it, can obtain corresponding data parameters simultaneously, and can be adjusted experimental temperature.
According to technical scheme: a kind of cooler for recycled exhaust gas performance comprehensive testing device, it is characterized in that: on workbench, fixedly mount burner, blender, transducer, described blender, transducer connect the first inflator and the second inflator respectively, described blender is connected with transducer by pipeline, backflow blower fan is set on described pipeline, described burner connects blender, described transducer, blender, burner are respectively provided with temperature sensor, and described temperature sensor connects central controller by wire.
As a further improvement on the present invention, described blender arranges opening.
As a further improvement on the present invention, the described first inflator other end arranges first interface.
As a further improvement on the present invention, described second inflator runs through transducer, and its one end arranges the second interface, and it runs through convenor section and communicates with transducer, and its other end is gas outlet.
The method have technical effect that: assay device of the present invention can be used to the simulated engine temperature of discharged air-flow, pressure, flow under each operating mode, and the various Matter Compositions contained by tail gas.Thus verify the property indices of detection cooler for recycled exhaust gas；Experimental provision of the present invention can depart from engine pedestal and carry out the properties test of cooler for recycled exhaust gas, substantially reduce the proving time, owing to using fuel oil operation fuel, the tail gas composition discharged during simulated engine work, the cooling effectiveness attenuation data that cooler for recycled exhaust gas is correct can be obtained, additionally cooler for recycled exhaust gas can also be done cold shock testing by the present invention, i.e. carries out the automatic switchover of different temperatures according to the time, verifies the thermal shock effect of cooler with this；The present invention is simple and reliable, easy to use, and cost of manufacture is low, it is easy to safeguard.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is cooler for recycled exhaust gas structural representation.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is further described.
As shown in Figure 1, 2, including workbench 1, burner 2, blender 3, transducer the 4, first inflator the 5, second inflator 6, central controller 8, backflow blower fan 9, pipeline 10, temperature sensor 11, opening 12 etc..
As shown in the figure, the present invention is a kind of cooler for recycled exhaust gas performance comprehensive testing device, burner 2, blender 3, transducer 4 is fixedly mounted on workbench 1, described blender 3, transducer 4 connect the first inflator 5 and the second inflator 6 respectively, described blender 3 is connected with transducer 4 by pipeline 10, backflow blower fan 9 is set on described pipeline 10, described burner 2 connects blender 3, described transducer 4, blender 3, burner 2 are respectively provided with temperature sensor 11, and described temperature sensor 11 connects central controller 8 by wire.
On described blender 3, opening 12 is set.
Described first inflator 5 other end arranges first interface.
Described second inflator 6 runs through transducer 4, and its one end arranges the second interface, and it runs through transducer 4 part and communicates with transducer 4, and its other end is gas outlet.
The work process of the present invention is as follows: when doing performance verification, first cooler for recycled exhaust gas is arranged on the interface of the first inflator 5 and the second inflator 6, arranges engine operating condition parameter on central controller 8: temperature, flow, time etc..After pressing start button, external fuel pump and lobe pump are started working, after igniting, high-temperature gas enters blender 3, in blender 3, combustion gas and cooling water carry out cold and hot exchange, central controller 8 regulates the ratio of air and fuel oil and obtains the output temperature needed and flow entrance cooler for recycled exhaust gas, combustion gas has part to be transported in blender 3 by backflow blower fan 9 after entering transducer 4, so can reduce the amplitude of the fuel gas temperature by cooler for recycled exhaust gas and pressure oscillation, the temperature at cooler two ends can be shown and record on central controller 8 simultaneously, flow and coolant water temperature.This device is mainly mutually coordinated by feedback control distributive value, air capacity, blender and transducer and the backflow blower fan of sensor so that the output temperature of gas, pressure steadily and reach the requirement set.
Assay device of the present invention can be used to the simulated engine temperature of discharged air-flow, pressure, flow under each operating mode, and the various Matter Compositions contained by tail gas.Thus verify the property indices of detection cooler for recycled exhaust gas；Experimental provision of the present invention can depart from engine pedestal and carry out the properties test of cooler for recycled exhaust gas, substantially reduce the proving time, owing to using fuel oil operation fuel, the tail gas composition discharged during simulated engine work, the cooling effectiveness attenuation data that cooler for recycled exhaust gas is correct can be obtained, additionally cooler for recycled exhaust gas can also be done cold shock testing by the present invention, i.e. carries out the automatic switchover of different temperatures according to the time, verifies the thermal shock effect of cooler with this；The present invention is simple and reliable, easy to use, and cost of manufacture is low, it is easy to safeguard.
