Embodiment Construction

[0037] The present invention will be further described now in conjunction with accompanying drawing.

[0038] The water circulation system in the locomotive needs to be heated by an external ground heat source under static conditions such as standby or deactivation. In the present invention, the ground heat source is called the ground heating heat source main system, and the water circulation system in the locomotive is called the locomotive water system. The static heating isolation heat exchange equipment for a diesel locomotive of the present invention is connected between the ground heating heat source main system and the locomotive water system to realize functions such as heat exchange and water addition.

[0039] refer to figure 1 , in one embodiment, the static heating isolation heat exchange equipment for a diesel locomotive of the present invention includes: a heat exchange heat source pipeline, a locomotive heating pipeline, a heat exchanger 3, a circulation pump 4...

Abstract

The invention relates to a static warming isolation heat exchange device of an internal combustion locomotive. The static warming isolation heat exchange device of the internal combustion locomotive comprises a heat exchange heat source pipeline, a locomotive warming pipeline, a heat exchanger, a circulating pump, a regulating valve and a master controller, wherein the static warming isolation heat exchange device of the internal combustion locomotive is connected onto a ground warming heat source main system through the heat exchange heat source pipeline, the locomotive warming pipeline is connected onto a locomotive water system, the heat exchange heat source pipeline and the locomotive warming pipeline are both connected onto the heat exchanger, the circulating pump is connected onto the locomotive warming pipeline, a communicating pipe provided with the regulating valve is installed between the heat exchange heat source pipeline and the locomotive warming pipeline, and the circulating pump and the regulating valve both work under control of the master controller.

Description

technical field [0001] The invention relates to the field of maintenance of diesel locomotives, in particular to static heating and isolation heat exchange equipment for diesel locomotives. Background technique [0002] In northern China, due to the low ambient temperature in winter, when diesel locomotives are on standby, in order to ensure that the oil and water temperature of the locomotive remains above the required temperature for normal operation of the locomotive, or to avoid machine breakage accidents due to frozen pipelines when the diesel locomotive is out of service for a long time, Must find a way to carry out the heating operation of locomotive oil water. The most commonly used method at present is to stop the locomotive but not stop it, and keep the oil and water temperature within the specified range by keeping the locomotive in operation. The problems with this method mainly include: [0003] 1. Consumes a lot of fuel and lubricating oil, resulting in high ...
