Abstract
The utility model discloses an engine preheating system for a road roller, which is applied to road rollers. The system consists of a preheating controller, a preheating relay, a key switch, a temperature sensor, an indicator lamp, an electric heating plug and a storage battery. When the key switch is turned to the position of on and when the temperature sensor detects that the temperature of cooling liquid of an engine is below 5 DEG C, the indicator lamp is on; the preheating controller outputs a signal to the preheating relay; the electric heating plug works; and the engine is heated. When the engine is heated to above 5 DEG C, the indicator lamp is off; the heating plug stops working; and the preheating process terminates. When the engine is started, the key switch is communicated with the port of the preheating controller 5; meanwhile the preheating controller outputs a signal again to the preheating relay; the heating plug is electrified to continue heating. When the temperature sensor detects that the temperature of the cooling liquid of the engine is above 25 DEG C, the heating plug stops working, and the whole preheating process terminates. The system can quickly start the engine.
Description
Technical field
The utility model relates to road roller engine warming up control technique.
Background technique
Road roller belongs to the category of road equipment in engineering machinery, can be divided into several types such as static pressure type road roller, vibrating roller, impact roller according to compaction theory.Road roller is that general being difficult to starts under the very low situation of temperature in winter, often needs startup repeatedly to get up engine start, exhausts the electric energy of storage battery easily, makes to start once more and can't normally carry out.In order under the very low situation of temperature, fast engine start to be got up, generally all adopt method to engine warming up.
Please refer to Fig. 1, Fig. 1 is the existing system circuit diagram that adopts manual preheating method to realize engine warming up.
As shown in the figure, press preheating button (2), preheating relay (3) coil is charged, its contact 30 and 87 closures, and electric current flows to glow plug (4) by lead from storage battery 1, glow plug (4) work, thus realization is to the heating of motor.Unclamp preheating button (2), the contact return, preheating relay (3) coil losing electricity, its contact 30 and 87 disconnects, and glow plug (4) quits work, and motor stops heating.
Adopt manual preheating method can realize engine warming up, but shortcoming is: 1. preheating button time of pressing can only be determined by experience, causes preheating and preheating not enough easily.2. can't judge in time whether motor needs preheating.
Therefore, working out a kind of automatic pre-heating system is those skilled in the art's technical issues that need to address.
The model utility content
The utility model purpose provides a kind of road roller preheating system for engine, is used for the preheating and the igniting of motor, can realize heating and ignition function to motor easily automatically, saves the energy of storage battery.
For solving the problems of the technologies described above, the utility model provides a kind of road roller preheating system for engine, is used for the igniting of road roller motor.It is characterized in that: system is made up of pre-heat controller, preheating relay, key operation, temperature transducer, tutorial light, glow plug, storage battery.The a pin of pre-heat controller links to each other with tutorial light, and the b pin links to each other with key operation on port, c pin ground connection, and the d pin links to each other with temperature transducer, and the e pin links to each other with key operation start port, and the f pin links to each other with preheating relay, and the g pin links to each other with storage battery is anodal.When key operation pushed the on position, if temperature transducer detects engine coolant temperature when being lower than 5 ℃, tutorial light was bright, and the preheating controller output signal is given preheating relay, glow plug work, motor heating.When being heated to more than 5 ℃, tutorial light extinguishes, and glow plug quits work, and heating process finishes in advance.Key operation is connected pre-heat controller 5 ports during engine start, and this moment, pre-heat controller outputed signal to preheating relay again, and the glow plug energising continues heating.When temperature transducer detected engine coolant temperature and is higher than 25 ℃, glow plug quit work, and whole warm finishes.This system motor capable of fast starting.So just realize twice automatic warm of motor, realize automatic igniting, reduce the energy that uses storage battery simultaneously to greatest extent motor.
Description of drawings
Fig. 1 is the manual pre-heating system circuit diagram of motor that generally adopts now;
Fig. 2 is a kind of preheating system for engine circuit diagram provided by the utility model;
The pairing component names of numeral number is as follows among the figure:
1. storage battery 2. preheating buttons 3. preheating relays 4. glow plugs 5. key operationes 6. tutorial light 7. temperature transducers
8. pre-heat controller.
Embodiment
The utility model provides a kind of road roller preheating system for engine, is used for the preheating and the igniting of motor, can realize heating and ignition function to motor easily automatically, saves the energy of storage battery.
In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 2, Fig. 2 is a kind of road roller preheating system for engine circuit diagram provided by the utility model; System is made up of storage battery (1), preheating button (2), preheating relay (3), glow plug (4), key operation (5), tutorial light (6), temperature transducer (7), pre-heat controller elements such as (8).The a pin of pre-heat controller (8) links to each other with pre-thermal light (6), the b pin links to each other with the on port of key operation (5), c pin ground connection, the d pin links to each other with temperature transducer (7), the e pin links to each other with the start port of key operation (5), the f pin links to each other with preheating relay (3), and the g pin links to each other with the positive pole of storage battery (1).
When road roller is prepared igniting, at first to get to the on state position to key operation (5), if the numerical value that this moment, pre-heat controller (8) collected temperature transducer (7) is during less than 5 ℃, tutorial light lights, controller (8) outputs signal to preheating relay (3), preheating relay (3) make contact, glow plug (4) work, motor begins heating.When temperature rose to more than 5 ℃, pre-heat controller (8) stopped to output signal to preheating relay (3), and glow plug (4) quits work, and tutorial light (6) extinguishes, and heating process finishes in advance.This moment, motor can start.When the start port of key operation (5) is connected, the starting motor running, simultaneously pre-heat controller (8) outputs signal to preheating relay (3) again, preheating relay (3) contact 30 and 87 terminal closures, glow plug (4) work, beginning secondary warm.When heating-up temperature was higher than 25 ℃, pre-heat controller (8) stopped to output signal to preheating relay (3), and preheating relay (3) contact 30 and 87 terminals disconnect, and glow plug (4) quits work, and whole heating process finishes.That is to say that temperature is below 5 ℃ the time, key operation under the on state, the automatic preheating of motor, when being heated to more than 5 ℃, tutorial light extinguishes.Heating process finishes in advance.In the time of temperature 5-25 ℃, key operation under the start state, the automatic secondary preheating of motor.When temperature does not need preheating in time more than 25 ℃.So just realize twice automatic warm of motor, reduce the energy that uses storage battery to greatest extent.
