Below specifically describe the heating work process of this diesel oil oil way heating unit:
When ignition switch, the first switch opens, the first control relay circuit is connected, and first control circuit starts, the first relay working circuit closure, the heater wire assembly circuit is connected, and the heater wire assembly is started working, and heater wire starts the diesel oil in oil pipe is heated.
The diesel fuel temperature at temperature detect switch (TDS) Real-Time Monitoring filter cleaner place, when monitoring diesel fuel temperature lower than 5 ℃, temperature detect switch (TDS) is connected automatically.Because first control circuit starts, the the second control relay circuit closure be connected with this temperature detect switch (TDS), second control circuit is connected, heating stick assembly working circuit is connected, the heating stick assembly is started working, heating stick starts the diesel oil in filter cleaner is heated, and work indicator light is opened simultaneously.
At heating stick to the diesel heating in filter cleaner after a period of time, when the diesel fuel temperature that real-time monitors the filter cleaner place when temperature detect switch (TDS) arrives 25 ℃, the temperature detect switch (TDS) automatic disconnection, the second control relay circuit disconnects, the working circuit of heating stick assembly disconnects, heating stick stops heating, and work indicator light extinguishes.Further, when temperature detect switch (TDS) real-time monitors diesel fuel temperature in filter cleaner lower than 5 ℃, temperature detect switch (TDS) is connected automatically, the second control relay circuit is connected, the working circuit of heating stick assembly is connected, the heating stick assembly starts task again, and heating stick is heated again to the diesel oil in filter cleaner.
Need to illustrate, the work of heater wire assembly and heating stick assembly is carried out respectively, as long as ignition switch and the first switch closure, the heater wire assembly is just always in running order, but the heating stick assembly is only closed at ignition switch and the first switch, temperature detect switch (TDS) is when also closed, just in running order.So when temperature detect switch (TDS) monitors oil temperature in filter cleaner and reaches 25 ℃, temperature detect switch (TDS) disconnects, the working circuit of heating stick assembly disconnects, heating stick stops heating, but the heater wire assembly still works on, diesel oil in oil pipe and fuel sucking pipe between fuel tank and coarse cleaner is continued to heating, to guarantee that in oil pipe, diesel oil keeps good mobility.
Adding of temperature detect switch (TDS), precision has been controlled the work of heating stick, has well controlled the oil temperature in the filter cleaner cavity, makes heating safer.
