Abstract
An oxygen sensor experiment device for automobiles is provided, comprising an experiment table top, an experiment box under the experiment table top, and an iron core in the experiment box. The iron core contains a closed intracavity, with the upper port of the intracavity enclosed connected to the oxygen sensor. The iron core has an electric heater mounted on the outside and a thermocouple mounted on the wall of the intracavity. The intracavity is connected with a vacuum exhaust tube and an air intake control tube. The experiment table top is mounted with an electric controller which is connected to the electric heater, a temperature measurement instrument which is connected to the thermocouple, a sealing plug which is connected to the vacuum exhaust tube, and an oxygen content control valve which is connected to the air intake control tube. The electric heater heats the oxygen sensor to the set temperature, adjusts the vacuum degree of the intracavity of the iron core, and changes the oxygen content surrounding the oxygen sensor. In this way, the signal for the oxygen content change can be realized, and students in the automobile profession can have a deeper understanding of the oxygen sensor. The device may also be used by manufacturers to test the oxygen sensors.
Description
Technical field
The utility model relates to a kind of teaching demonstration device, particularly a kind of automotive oxygen sensor experimental provision.
Background technology
The principle of work of lambda sensor is: lambda sensor is at the upper end position of automobile engine exhaust pipe, the oxygen level of Control of Automobile engine exhaust, and the automobile controlling computer receives the signal of lambda sensor, calculates to cross the computer plate, distributive value is accurately controlled again.In the prior art, in the automotive oxygen sensor experimental provision, the interior burning things which may cause a fire disaster of the employing metal catheter that has Germany to produce adds heated oxygen sensor, lambda sensor is loaded on the position that changes conduit upper end outlet opening, realize changing oxygen content, provide the variable signal of lambda sensor to carry out teaching demonstration.This device causes poor safety performance owing to adopt the naked light heating, and experimentation is cumbersome.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of practicality directly perceived, has tested automotive oxygen sensor experimental provision easily.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of automotive oxygen sensor experimental provision, be characterized in: it is provided with an experiment table top, below the experiment table top, be provided with an experimental box, iron core is housed in the experimental box, be provided with an airtight inner chamber in the iron core, the sealing of joining of inner chamber upper port and lambda sensor, electric heater is equipped with in outside at iron core, on the iron core internal chamber wall thermopair is housed, the vacuum that is provided with that communicates with the iron core inner chamber is taken out pipe and air inlet adjustment pipe, is provided with the electric controller that joins with electric heater on described experiment table top, the temperature measuring set that is connected with thermopair, take out sealing that pipe joins oxygen content variable valve stifled and that join with the air inlet adjustment pipe with vacuum.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, between iron core and the experiment table top insulating is housed.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, described vacuum take out the coil pipe of pipe by some circles around experimental box outside again with the experiment table top on sealing block up and be connected.
In process of the test, at first lambda sensor is heated by electric heater, reach the temperature of setting, by the oxygen content variable valve, adjust iron core inner chamber vacuum tightness, change the oxygen level of lambda sensor surrounding space, realize the oxygen content change signal.Utilize oxygen sensor device teaching experimental base of the present utility model, the most significant effect is to make the understanding of automobile major student intensification to automotive oxygen sensor.This device also can be used for the manufacturer of lambda sensor, and its performance is tested.
Description of drawings
Accompanying drawing is a structure diagram of the present utility model.
