By adopting the technical scheme, the liquid level sensor of the expansion tank does not make contact with the cooling liquid, the cost is low, the reliability is good, the sealing performance is good, and maintenance is easy. The floater can not be clamped or fall, the reliability is good, and the permanent magnet materials can be free of maintenance.
Description
Technical field
The utility model belongs to auto parts machinery field, particularly a kind of cooling system swelling water tank with level monitoring and warning function.
Background technique
The cooling system of heavy-duty car is most important on motor impact, in use usually can, because of the very few ablation that causes engine cooling ability degradation or even casing wall of cooling liquid, cause huge economic loss.The main cause that causes this loss is to have neglected the making regular check on of swelling water tank, and causes coolant consumption totally.Therefore studying a kind of expansion tank can Real-Time Monitoring high water tank, when liquid level drops to warning position, can send signal, and prompting adds inject cooling liquid, eliminates passive hidden danger, and this seems extremely important.Existing swelling water tank major part has liquid level warning function, but do not have the highest liquid level prompt facility, and its structure is sensor and cooling liquid contact-type, thereby cooling liquid is easily revealed generation cooling system failure.
Model utility content
The purpose of this utility model is to provide a kind of employing sensor and the discontiguous mounting structure of cooling liquid, and can realize the swelling water tank that minimum, high liquid level warning, cooling-liquid level change the functions such as prompting.
To achieve these goals, the utility model adopts following technological scheme.
The cooling system with liquid level warning function described in the utility model comprises with swelling water tank: casing, buckle, upper and lower spacing boss, liquid level sensor, float.
Wherein, casing is fixedly connected with by upper and lower casing, and inside is cavity;
Lower shell body has sensor shell and bayonet unit, and buckle is positioned at sensor shell bottom;
Sensor shell is goed deep into lower shell body inside, is shaped as cylindricality, is used for installing liquid level sensor;
Liquid level sensor has spacing scrobicular ring, and spacing scrobicular ring coordinates liquid level sensor is fixed in sensor shell and is not contacted with cooling liquid with bayonet unit, does not affect the sealing of casing, and is easy to safeguard;
At box house, in the sensor shell of lower shell body, cover has float, and this float can fluctuate along sensor shell short transverse;
Float has magnet ring, is positioned at liquid level sensor induction zone, thereby can be responded to prompting cooling-liquid level by liquid level sensor, changes.
Preferably, upper and lower casing inside has respectively positive stop lug boss, the scope that restriction float fluctuates, and float can not block or come off in location free procedure, and reliability is high.
Preferably, liquid level sensor adopts dry-reed tube switch or Hall switch, and magnet ring adopts permanent-magnet material, and permanent-magnet material can ensure non-maintaining.
Preferably, sensor shell is shaped as cylindrical, and the float effect that fluctuates is best.
Preferably, casing is welded by upper and lower casing, adopts welding manner cost low, good reliability.
The cooling system with liquid level warning function described in the utility model uses swelling water tank working principle as follows:
In casing, be filled with cooling liquid, float short transverse along sensor shell in casing fluctuates, and is fixed on the liquid level sensor induction float position in sensor shell, and to entire car controller, transmits liquid level information by external circuit by buckle;
In casing, cooling liquid is abundant, and liquid level sensor senses that float is positioned at the highest warning position, by external circuit, to entire car controller, transmits high liquid level warning information;
In casing, cooling liquid is not enough, and liquid level sensor senses that float is positioned at minimum warning position, transmits minimum liquid level warning message by external circuit to entire car controller.
The cooling system swelling water tank with liquid level warning function that adopts technique scheme, casing is welded by upper and lower casing, and cost is low, good reliability.Liquid level sensor is installed on the cavity of sealing, do not contact with cooling liquid, and the good seal performance of casing, and be easy to safeguard.The upper and lower positive stop lug boss of having done in casing, float can not block or come off in location free procedure, and reliability is high, and permanent-magnet material can ensure non-maintaining.
