As all the components in the device are connected based on the connecting mode of the automobile cooling system, the measured flow and pressure values can be much closer to the true value and can better reflect the real situation of the cooling system, so the measurement results are more reliable.
Description
Technical field
The present invention relates to the experimental measurement device of vehicle, be specifically related to a kind of measurement mechanism that fluid resistance in the automobile cooling system is carried out.
Background technology
In the cooling system of vehicle measurement of water system resistance to the pipe important because the water system resistance is the foundation of engine water pump type selecting.Measurement for some key point pressure and other parameters in the cooling system, significant, as providing the flow parameter that meets the real vehicle situation when carrying out the water tank performance test, make the measurement of water tank heat exchange property more accurate to the measurement of water tank import and export pressure; To the measurement of pump intake place pressure, and, can predict and prevent the generation of cavitation (in phenomenon in conjunction with temperature survey.
The measurement of cooling system water system resistance is at present mainly undertaken by test of parts monomer and calculation mode.The shortcoming of this mode is not take all factors into consideration the influence to the total resistance of water system of line arrangement, joint form and the engine water cell structure etc. of whole cooling system, the problem that this metering system causes is that measured value is inaccurate, with actual conditions bigger difference is arranged, can't know the problems such as pressure of concrete certain position.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of water system resistance measurement apparatus of vehicle cooling system, can more be met the measurement result of vehicle actual conditions.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of water system resistance measurement apparatus of vehicle cooling system, comprise matrix and the engine that is installed on the matrix, the expansion kettle, vehicle-mounted water pump, temperature-conserving valve, water tank and dim wind core body, described engine, the expansion kettle, vehicle-mounted water pump, temperature-conserving valve, water tank is connected by pipeline with the connected mode of dim wind core body according to described automobile cooling system, also be provided with flow sensor in the described pipeline and be positioned at vehicle-mounted water pump, engine, near water tank and the warm braw core body a plurality of pressure transducers, but a motor and a cylinder are installed also on the described matrix, described motor and vehicle-mounted water pump are in transmission connection, but described cylinder is connected with pipeline by a stop valve.
The invention has the beneficial effects as follows: because each element in the device connects according to the connected mode of real vehicle cooling system fully, the flow that records like this, force value can be more near actual values, more can react the truth of cooling system, measurement result is more true and reliable.Adopt measurement mechanism of the present invention, made things convenient for the layout of sensor, can record the force value of certain particular location as required.Can change fast elements such as engine, water tank, water pumps easily, to measure the influence of different elements cooling system water system resistance.Different with real vehicle is, the engine among the present invention is out-of-operation, and vehicle-mounted water pump is by driven by motor, the rotating speed of easier like this control water pump; But the temperature of liquid coolant is controlled by cylinder, and is also more convenient.
Preferably, the both sides of described vehicle-mounted water pump are equipped with pressure transducer.
Preferably, the both sides of described water tank are equipped with pressure transducer.
Preferably, also be provided with temperature sensor in the described pipeline.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is the synoptic diagram of a kind of water system resistance measurement apparatus of vehicle cooling system of the present invention.
Embodiment
As shown in Figure 1, water tank 1, dim wind core body 2, engine 3, expansion kettle 5, vehicle-mounted water pump 6 and temperature-conserving valve 7 are connected by pipeline, constitute closed circuit, this pipeline is identical with the actual connected mode of automobile cooling system, so the cooling system of simulated automotive well.Above-mentioned each element all is installed on the matrix (not shown).
Different with actual conditions on the automobile is, in device of the present invention, engine 3 is out-of-operation, just the cooling water pipeline with engine is connected in the above-mentioned pipeline, therefore relation is not in transmission connection between engine 3 and vehicle-mounted water pump 6 yet, the rotating speed of regulating motor 8 can be controlled the rotating speed of vehicle-mounted water pump 6 to 6 on vehicle-mounted water pump easily by the 8 drive work of a motor, and the different operating modes of simulated engine operation; Simultaneously, because engine does not turn round, can not produce the heat that coolant temperature is raise, but therefore device of the present invention also is provided with a cylinder 4, but cylinder 4 is connected with pipeline by a stop valve 11.But liquid coolant earlier is heated to assigned temperature in cylinder 4 after, opens stop valve 11 and make the liquid coolant after the heating be full of whole pipeline, and close stop valve 11, under the effect of vehicle-mounted water pump 6, liquid coolant just can form and circulate then.Like this, but utilize cylinder 4 just can control and simulate the temperature of liquid coolant easily.But above-mentioned motor 8 and cylinder 4 also are installed on the matrix.
According to Testing requirement, difference at pipeline is arranged flow sensor 10 and pressure transducer 9, such as in order to measure the water system resistance, can be in the both sides of water tank 1, positions such as (influent side and water outlet sides), the both sides of vehicle-mounted water pump 6 is provided with pressure transducer 9 respectively, calculate the water system resistance of this element by the variation of pressure at both sides, same engine 3 and near the of dim wind core body 2 also can be provided with pressure transducer 9; The temperature sensor (not shown) can also be set, to measure the temperature of liquid coolant in the pipeline in pipeline.When measuring another kind of engine to the influencing of whole water system resistance if desired, only need more reengine revision test and get final product, other element also is the same.
