Abstract
A normally open type electromagnetic flameout controller comprises a coil winding and a piston device. The coil winding comprises a parallel pull in coil winding and a keeping coil, the pull in coil winding and the keeping coil are provided with an interface line, an electronic protector is arranged on the interface line, the electronic protector is connected to the coil winding; the electronic protector is composed of an input terminal, a balanced resistance, two mosfets, a capacitance and two triodes arranged on the circuit board, the input terminal is connected with one terminal of the pull in coil winding and the keeping coil through lines, the other terminal of the pull in coil winding and the keeping coil are connected with D pole of a mosfet respectively, the S pole of the two mosfets is directly earthed, the input terminal is connected with G pole of the two mosfets at the same time through a control circuit formed by the balance resistance, the capacitance and two triodes. When the utility model is in the diesel engine working process, the coil is not charged and in an often open state to prevent the keeping coil from being burnt maintaining coil, so that the life-span of the electromagnetic flameout controller increase at least one times.
Description
Technical field
The utility model relates to the controller open in usual of the flame-out not charged long-term work of diesel engine oil-break that control vehicle, ship use.
Background technique
At present, diesel engine adopts the ignition by compression mode, not only will close electric switch when diesel engine is flame-out, also must cut off oil pump feed.At present, flame-out with pull bar control diesel engine oil-break, inconvenient operation; Flame-out with the flame-out controller control of closed type (long-term charged) electromagnetic type diesel engine oil-break, though easy to operate, burn coil easily, break down, poor reliability.
Summary of the invention
Flame-out in order to solve with the flame-out controller control of closed type (long-term charged) electromagnetic type diesel engine oil-break, burn coil easily, break down, the shortcoming of poor reliability, the utility model proposes the flame-out controller of electromagnetic type open in usual that diesel engine is used.
For this reason, the technical solution of the utility model is as follows: the electromagnetic type open in usual controller that stops working, comprise coil winding and piston apparatus, coil winding is positioned at housing, by pull in winding parallel with one another with keep coil and forms, pull in winding with keep coil and have interface line, piston apparatus is that a piston is positioned at the coil winding in-core, electronic protector is housed on the interface line, and electronic protector is connected with coil winding; It is characterized in that: described electronic protector is made up of on circuit board input terminal, ballast resistor, two field effect transistors, electric capacity, two triode arrangement; Input terminal is connected with terminal of keeping coil, pull in winding by circuit, another terminal of keeping coil, pull in winding are connected with the D utmost point of a field effect transistor respectively, the S of two field effect transistors is ground connection extremely directly, and input terminal is connected with the G utmost point of two field effect transistors by the control circuit of ballast resistor, electric capacity, two triode compositions simultaneously.
The piston of the flame-out controller of described electromagnetic type open in usual can directly act on the oily pull bar that stops of diesel engine oil pump.After the diesel engine electric switch is opened, pull in winding and to keep coil not charged, piston is in reset mode under the effect that stops oily pull bar, and the oil pump of diesel engine is opened the fuel feeding state that is in; When electric switch cut out, the electric weight of accumulating by electric capacity made field effect transistor saturated ending of time-delay, pull in winding and keep coil simultaneously electric, close oil circuit, oil pump stops pump oil, and the diesel engine oil-break is stopped working.
The flame-out controller of described electromagnetic type open in usual has been realized by electric switch control flame-out, easy for operation, when diesel engine is worked, coil is not charged, be in normally open, avoid keeping coil and burnt out, guarantee the trouble free service of electric component, make improve more than at least one times the working life of the flame-out controller of electromagnetic type.
