Fig. 1 is most preferred embodiment of the present utility model, is described further below in conjunction with 1 pair of the utility model of accompanying drawing.
In the prior art, electric heater adopts star connection to be connected with power lead, and after the supply line of electric heater connected, three electric heaters heated for carburetor simultaneously.In the utility model, as shown in Figure 1, three electric heaters of former star connection are divided into to two groups, by the gear switch circuit, switched.An end that connects successively normally opened contact KM2-1 ~ KM2-3 of contactor KM2 after live wire L1 ~ L3 series connection circuit breaker Q F1, other end difference series electrical well heater R2 ~ R3 of normally opened contact KM2-1 and normally opened contact KM2-3 connects the other end of normally opened contact KM2-2 afterwards simultaneously.The end of the normally opened contact KM1-1 of contactor KM1 is parallel between circuit breaker Q F1 and normally opened contact KM2-1, the other end of normally opened contact KM1-1 is parallel between circuit breaker Q F1 and normally opened contact KM2-2 after series electrical well heater R1 and normally opened contact KM1-2 successively, and electric heater R1 ~ R3 is divided into two groups of totally three gears.The live wire L3 that start button SA1 mono-end is parallel between circuit breaker Q F1 and normally opened contact KM2-3 is upper, and the other end is electric heater control circuit in parallel and temperature feedback circuit simultaneously.
Normally opened contact KA2-1, the linked switch SA2 that the electric heater control circuit comprises normally closed contact KA1-1, the relay K A2 of relay K A1 with and two interior switch contact SA2-1 ~ SA2-2, the coil of start button SA3, contactor KM1 ~ KM2.The normally closed contact KA1-1 of relay K A1 is in parallel with start button SA1, the end of two switch contact SA2-1 ~ SA2-2 after the normally opened contact KA2-1 of other end series relay KA2 in while linked switch SA2 in parallel, be parallel on zero line N after the coil of switch contact SA2-1 series contactor KM1; After the coil of switch contact SA2-2 series contactor KM2, be parallel on zero line N.Start button SA3 mono-end is connected in parallel between the coil of switch contact SA2-1 and contactor KM1, and the other end is connected in parallel between the coil of switch contact SA2-2 and contactor KM2.
The normally closed contact KA1-1 of relay K A1 and the normally opened contact KA2-1 of relay K A2 form the temperature control unit of electric heater control circuit; Linked switch SA2 with and interior two switch contact SA2-1 ~ SA2-2, start button SA3 form the gear switch unit of electric heater control circuit, three gears that electric heater R1 ~ R3 is formed switch; Contactor KM1 ~ KM2 forms the contact unit of electric heater control circuit, and two groups of electric heaters that respectively electric heater R1 ~ R3 formed are controlled.
Temperature feedback circuit comprises normally opened contact RT1-1 ~ RT1-2 of pressure controller RT1, the normally opened contact KM1-3 of the coil of relay K A1 ~ KA2, contactor KM1 and the normally opened contact KM2-4 of contactor KM2.The normally opened contact RT1-1 of pressure controller RT1 and the coil of relay K A1.Normally opened contact RT1-1 mono-end is in parallel with start button SA1, is parallel on zero line N after the coil of other end series relay KA1; The normally opened contact KM2-4 of the normally opened contact RT1-2 of pressure controller RT1, the normally opened contact KM1-3 of contactor KM1, contactor KM2 and the coil of relay K A2.Normally opened contact RT4-1 mono-end is in parallel with start button SA1, after the coil of other end series relay KA1, is parallel to zero line N upper, and normally opened contact KM1-3 and normally opened contact KM2-4 are parallel to normally opened contact RT1-2 two ends simultaneously.
The specific works process is as follows: carburetor control system of the present utility model can be used different gears according to Season select, and when summer, temperature is higher, only needs to select one group of electric heater to satisfy the demand.Now press linked switch SA2, switch contact SA2-1 adhesive, Simultaneous Switching contact SA2-2 disconnects.In the time of need to heating, at first connect circuit breaker Q F1, then press start button SA1, now in carburetor, temperature is lower, lower than the lowest temperature of setting, now pressure controller RT1 action, normally opened contact RT1-2 adhesive, the action that powers on of the coil of relay K A2, its normally opened contact KA2-1 adhesive, the coil of the contactor KM1 action that powers on, normally opened contact KM1-1 ~ KM1-2 adhesive, connect electric heater R1, start as the carburetor heating.Normally opened contact KM1-3 adhesive simultaneously, make relay K A2 two ends keep the state powered on.
When the rising of the pressure following temperature in carburetor reaches the upper pressure limit of setting, pressure controller RT1 action, normally opened contact RT1-1 adhesive, the coil of the relay K A1 action that powers on, its normally closed contact KA1-1 disconnects, contactor KM1 coil losing electricity, normally opened contact KM1-1 ~ KM1-2 disconnects, and electric heater R1 quits work, when the pressure following temperature in carburetor reduces and prescribes a time limit under falling pressure, restart work, and so forth.
When winter, temperature is lower, presses linked switch SA2 it is resetted, and now switch contact SA2-1 disconnects, and switch contact SA2-2 connects.In the time of need to heating, at first connect circuit breaker Q F1, then press start button SA1, now in carburetor, temperature is lower, lower than the lowest temperature of setting, now pressure controller RT1 action, normally opened contact RT1-2 adhesive, relay K A2 action, its normally opened contact KA2-1 adhesive, thus make the action that powers on of the coil of contactor KM2, normally opened contact KM2-1 ~ KM2-3 adhesive, two groups of electric heater R2 ~ R3 connect simultaneously, start as the carburetor heating.Normally opened contact KM2-4 adhesive simultaneously, make relay K A2 two ends keep the state powered on.
When the rising of the pressure following temperature in carburetor reaches the upper pressure limit of setting, pressure controller RT1 action, normally opened contact RT1-1 adhesive, the coil of relay K A1 powers on, and its normally closed contact KA1-1 disconnects, the two ends power down of contactor KM2 coil, normally opened contact KM2-1 ~ KM2-3 disconnects, and electric heater R2 ~ R3 quits work, when the pressure following temperature in carburetor reduces and prescribes a time limit under falling pressure, restart work, and so forth.
When temperature is extremely low, press start button SA3, now the coil of contactor KM1 ~ KM2 powers on simultaneously, connects three groups of electric heater R1 ~ R3, simultaneously carburetor is heated, and its course of work is identical with the above-mentioned course of work.
The above, it is only preferred embodiment of the present utility model, be not the utility model to be done to the restriction of other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away from, to any simple modification, equivalent variations and remodeling that above embodiment does, still belong to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
