Abstract
This air pump overrun control, comprising: main relay, time delay relay, air pump.The atmospheric pressure value needed according to car load adjusts the most highpressure of pressure switch, when after closed air pump switch, if air pressure reaches best air pressure, now pressure switch disconnects, adhesive after the coil electricity of time delay relay, air pump and power connection, start working, after certain time-delay, time delay relay disconnects, and air pump cuts out, and can guarantee that exsiccator disconnects after being vented the certain hour that can work on automatically smoothly.And if air pressure lower than setting pressure time, pressure switch closes, now the coil connection work of main relay, and air pump is by the Chang Kaiduan of main relay and power connection, and now air pump unlatching work is to reach the exhaust air pressure of exsiccator smoothly.
Description
Technical field
The utility model relates to automotive controls technical field, is specifically related to a kind of air pump control gear.
Background technique
Air pump control system is the important component part of new-energy automobile electrical source of power, air pump need coordinate with exsiccator and controls, if the stopping air pressure node of air pump is too low, then can cause the exhaust air pressure that cannot reach exsiccator, if too high, then can work because of the scavenging action of exsiccator always.
Summary of the invention
The utility model, in order to overcome the deficiency of above technology, provides a kind of exsiccator that can make and is vented smoothly after closing air pump switch and is vented rear air pump overrun control of automatically closing.
The utility model overcomes the technological scheme that its technical problem adopts:
This air pump overrun control, comprising:
Main relay, one control end is connected to power supply through air pump switch, and its another control end is through pressure switch ground connection;
Time delay relay, one control end is connected to the normally closed output terminal of main relay, its another control end ground connection;
Air pump, one end ground connection, its other end is connected to the output terminal often driving output terminal and time delay relay of main relay;
The input end of described main relay and the input end of time delay relay are connected to power supply through air pump switch respectively.
The beneficial effects of the utility model are: the atmospheric pressure value needed according to car load adjusts the most highpressure of pressure switch, when after closed air pump switch, if air pressure reaches best air pressure, now pressure switch disconnects, adhesive after the coil electricity of time delay relay, air pump and power connection, start working, after certain time-delay, time delay relay disconnects, and air pump cuts out, and exsiccator device of can going bail for smoothly disconnects after being vented the certain hour that can work on automatically.And if air pressure lower than setting pressure time, pressure switch closes, now the coil connection work of main relay, and air pump is by the Chang Kaiduan of main relay and power connection, and now air pump unlatching work is to reach the exhaust air pressure of exsiccator smoothly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1. pressure switch 2. air pump switch 3. air pump 4. main relay 5. time delay relay.
Embodiment
Be described further below in conjunction with accompanying drawing 1 pair of the utility model.
This air pump overrun control, comprising:
Main relay 4, one control end is connected to power supply through air pump switch 2, and its another control end is through pressure switch 1 ground connection; Time delay relay 5, one control end is connected to the normally closed output terminal of main relay 4, its another control end ground connection; Air pump 3, one end ground connection, its other end is connected to the output terminal often driving output terminal and time delay relay 5 of main relay 4; The input end of main relay 4 and the input end of time delay relay 5 are connected to power supply through air pump switch 2 respectively.The atmospheric pressure value needed according to car load adjusts the most highpressure of pressure switch 1, when after closed air pump switch 2, if air pressure reaches best air pressure, now pressure switch 1 disconnects, adhesive after the coil electricity of time delay relay 5, air pump 3 and power connection, start working, after certain time-delay, time delay relay 5 disconnects, and air pump 3 cuts out, and exsiccator device of can going bail for smoothly disconnects after being vented the certain hour that can work on automatically.And if air pressure lower than setting pressure time, pressure switch 1 closes, the now coil connection work of main relay 4, and air pump 3 is by the Chang Kaiduan of main relay 4 and power connection, and now air pump unlatching work is to reach the exhaust air pressure of exsiccator smoothly.
