Abstract
The invention relates to a cooling water system of a diesel locomotive. The cooling water system comprises an inner diesel engine body water way, an outer diesel engine body cooling water inlet/outlet pipeline, a radiator and an expansion tank, the expansion tank is communicated with a water inlet pipeline, and the volume and the height of the expansion tank enable the liquid level of cooling water in the expansion tank to be lower than the bottom of the radiator but higher than the highest water level of cooling water in a diesel engine body when a diesel engine stops. Since cooling water in the radiator can return to the expansion tank after the diesel engine stops, frost cracking of the radiator caused by cooling water in the radiator after the diesel engine stops can be prevented when the outside air temperature is cold. Meanwhile, the cooling water system inside the diesel engine body is guaranteed to be filled with cooling water after the diesel engine stops, and starts to cycle immediately after the diesel engine starts again.
Description
Technical field
The present invention relates to a kind of Cooling Water of Diesel Locomotive system, belong to Machining Technology field railway locomotive technical field.
Background technique
For many years, there is a kind of common recognition in design in the Cooling Water of Diesel Locomotive system, that is: for reaching the filter loss of compensation high and low temperature water pump spindle sealing place, allowance for expansion space after the compensation cooling water is heated, and the air in the eliminating cooling water system and steam, the swelling water tank setting height(from bottom) must be placed more than the radiator.Because the swelling water tank position is higher than radiator, after the upper water, the radiator that belongs to cooling water system is full of cooling water all the time.Because radiator is than other position rapid heat dissipation of system, after diesel engine stop, in case ambient temperature is lower than zero degree, the cooling water in the radiator will freeze at first fast, and this often causes the generation of radiator bursting by freezing situation.
Summary of the invention
Purpose of the present invention overcomes the deficiency of above-mentioned prior art exactly; a kind of Cooling Water of Diesel Locomotive system is provided; can be after diesel engine of locomotive be shut down just the cooling water in the radiator is emptying, guarantee again to have in the diesel engine enough cooling waters to guarantee again to rise at any time machine simultaneously.
The object of the present invention is achieved like this: a kind of Cooling Water of Diesel Locomotive system; comprise that water route, the external cooling water of diesel engine advance/go out pipeline, radiator and swelling water tank in the diesel-engine body; it is characterized in that swelling water tank is communicated with inlet pipeline; the volume of swelling water tank and height should make the cooling water liquid level height in it be lower than the radiator bottom when diesel engine stop, but are higher than cooling water highest water level in the diesel-engine body.
Technological scheme of the present invention; because the cooling water in the radiator can all be got back in the swelling water tank after diesel engine stop; thereby can prevent that outside air temperature is cold the time, still have cooling water in the radiator after the diesel engine stop and cause the generation of radiator bursting by freezing situation.Simultaneously, guarantee again after the diesel engine stop still cooling water abrim of internal body cooling water system, can begin immediately circulation when again playing machine.
Description of drawings
Fig. 1 is the Cooling Water of Diesel Locomotive system principle schematic diagram of the embodiment of the invention.
Mark among the figure: water route in the 1-body, the outer inlet pipeline of 2-body, the outer rising pipe of 3-body, 4-radiator, 5-swelling water tank, 6-cooling water liquid level, 7-diesel engine.
Embodiment
For the purpose, technological scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technological scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiments.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment who obtains under the creative work prerequisite.
Referring to Fig. 1; the Cooling Water of Diesel Locomotive system of the present embodiment; comprise water route 1 in the diesel-engine body, the outer inlet pipeline 2 of body, the outer rising pipe 3 of body, radiator 4 and swelling water tank 5; the bottom of swelling water tank 5 is communicated with inlet pipeline 2; the volume of swelling water tank 5 and highly make the height of the cooling water liquid level 6 in it when diesel engine stop, be lower than the radiator bottom, but be higher than cooling water highest water level in diesel engine 7 bodies.
When diesel engine played machine, abrim cooling water began circulation immediately in the body; And when shutting down, the cooling water in the radiator then can be emptying rapidly, flows into swelling water tank, causes the radiator bursting by freezing when preventing low temperature.
It should be noted that at last: above embodiment only in order to technological scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technological scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characteristics wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technological scheme.
