Novel low constant speed device for internal combustion locomotive

Abstract

The invention relates to a low constant speed device, in particular to a novel low constant speed device for an internal combustion locomotive. A host of the low constant speed device is connected with a I-terminal display and a II-terminal display, the host of the low constant speed device is connected with a CF tachogenerator on the locomotive through an XKJ relay, one end of a switch on one side of the XKJ relay is connected with an original circuit, and the other end of the switch is connected with a PWM pulse width modulator; an SCM pressure regulating and processing plate on the host of the low constant speed device is connected with a principal voltage signal, a D / A digital-to-analog converter is connected with a principal current signal, an F / signal processor is connected with a DF16 specially-made photoelectric rotational speed sensor, and an option switch is connected with the XKJ relay. The low constant speed device reasonably uses the power of a locomotive internal combustion engine, so that the waste of energy is reduced, and at the same time, the maintenance is convenient. The excitation control of the device is independent control, so that the device can be mounted on other various direct-current transmission internal combustion locomotives to realize the function of low constant speed control for the other various direct-current transmission internal combustion locomotives.

Description

technical field [0001] The invention relates to a low constant speed device, in particular to a new low constant speed device for a diesel locomotive. Background technique [0002] While the Railway Corporation introduced the new Harmony locomotives, the Dongfeng 4 diesel locomotives used by some national railways were used in coal mines and other industrial and mining enterprises. In the process of coal transportation, the speed of the mine car is required to be kept at about 1km / h. In the original locomotive design, the speed of the locomotive was only controlled by changing the controller handle of the locomotive driver to change the power of the diesel engine, and it was difficult to require constant speed operation at low speeds. However, the adoption of artificial control will be very arbitrary, and constant speed control cannot be realized. Contents of the invention [0003] In order to overcome the disadvantages of difficult operation of the existing locomotives ...
