Utility model works principle：Flame-out port P4 is the flame-out line for connecting igniter, and level signal is first just to bear afterwards
Positive pulse signal again, wherein positive pulse is no more than 30V, and negative pulse is the firing pulse for being more than 300V, triode Q2, Q3 structure
At darlington structure.
Start work-based logic when unit：
1, when lacking machine oil, machine oil controlling alarm port P2 is connected to ground, and the positive pulse of flame-out port P4 passes through two
Pole pipe D3, capacitance C1 and the circuits diode D1 are charged to capacitance C1.When the igniting negative pulse of flame-out port P4 arrives, diode
D1 and diode D3 cut-offs, for capacitance C1 by resistance R2, diode D2, thyristor Q1, resistance R1 forming circuit electric discharges, making can
Silicone tube Q1 work is controlled, negative pulse shorted to earth of lighting a fire is realized to the flame-out of unit or does not start control.At this point, user's control end
Mouth P3 does not work.
2, when unit does not lack machine oil, i.e. machine oil controlling alarm port P2 is hanging, herein in two kinds of situation：
A, make user's control port P3 hanging when there are other failures：The positive pulse of flame-out port P4 does not work, until
When negative pulse arrives, the potential of ground wire is high level relative to flame-out port P4.Since rotating speed is too low at this time, resistance R7, resistance
It is slow that the integrating circuit that R9, capacitance C3 are constituted makes the voltage at the both ends capacitance C3 rise, after resistance R6 and resistance R8 partial pressures not
Triode Q3 can be made to work.At this point, ground wire high level passes through another circuit, i.e. diode D7, resistance R4, resistance R5 and two
Pole pipe D6, controls silicon-controlled Q1 work, and the realization of flame-out port P4 negative pulse shorted to earths is not started unit function.
B, when P3 conductings in user's control port are connected to ground wire：The positive pulse of same flame-out port P4 does not work, and bears
Ground wire is high level relative to flame-out port P4 when pulse arrives, although rotating speed is low at this time, due to resistance R10, resistance R11
Resistance value it is small more than resistance R7 and resistance R9, therefore the integrating circuit that resistance R10, resistance R11 and capacitance C3 are constituted makes capacitance C3
The voltage at both ends rises rapidly, still triode Q3 is enough made to enter saturation conduction state after resistance R6, resistance R8 partial pressures, will
The level of the tie point of resistance R5, diode D6 drags down, to make silicon-controlled Q1 there is no trigger signal without working, port of stopping working
The igniting negative pulse of P4 still exists, and unit can normally start.
Work-based logic after unit starting：
After unit starting, since diode D4, resistance R7, resistance R9 are connected with ground wire for a long time with the circuits capacitance C3,
When rotating speed reaches control rotating speed 1700rpm ± 150rpm or more, even if the voltage at the both ends capacitance C3 is by resistance R6 and resistance R8
Partial pressure also can make triode Q3 enter saturation conduction state, so as to cause no matter whether user's control port P3 is grounded all no longer
It works, it is therefore prevented that the maloperation of user.In this case, product can only be by machine oil controlling alarm port P2 control units
It is no flame-out.Wherein rotating speed control point can be adjusted by capacitance C3 or resistance R8.
