Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.Should be understood that embodiment described herein only is used for description and interpretation the utility model, is not limited to the utility model.
As shown in Figure 1, a kind of pre-heating system of internal combustion locomotive, this pre-heating system comprises successively by continuous water pump 1, Preheating unit 2, first heating equipment 3 and first valve 4 that constitutes first circulation waterway of pipeline, wherein, this internal combustion locomotive pre-heating system also comprises water replenishing device 5 and water-feeding valve 6, and described water replenishing device 5 is by described water-feeding valve 6 other being connected between described first valve 4 and the water pump 1.
The water of this pre-heating system inside can be flowing that first circulation waterway moves in circles, and water can lose and consume in the process of running.The pre-heating system of this internal combustion locomotive can directly carry out the moisturizing operation by water replenishing device 5, when the pre-heating system water shortage, closes first valve 4 earlier, starts water pump 1, opens water-feeding valve 6, thereby pre-heating system is carried out automatic water supplement.When moisturizing finishes, close water-feeding valve 6 earlier, switch off the pump 1, open first valve 4 again, start water pump 1, make pre-heating system run well.Thereby, needn't add water to roof by artificial again water lift, independent water charging system also need not be set pre-heating system is carried out moisturizing, make this pre-heating system can carry out moisturizing safely, fast and easily, and simple in structure, realize that cost is lower.
Water replenishing device 5 can utilize the wet pit that is arranged on the railway website, perhaps water-feeding valve 6 is directly connected to the water supply installation etc. that adds water to internal combustion locomotive, and the form that is not limited to fix is operated as long as can realize safe, moisturizing easily.Preferably, described water replenishing device 5 is a water storage tank.Water replenishing device 5 can be set directly on the internal combustion locomotive, carry, thereby can carry out moisturizing to pre-heating system at any time with car.So also need attached match equipment to cooperate, thereby the operation independence of this pre-heating system is better.
Because this pre-heating system needs a large amount of hot water, as heat transferring medium, thereby fuel oil, machine oil and cool air etc. are heated, therefore Preheating unit 2 first heat exchanging media (being water) are set and heat.Preheating unit 2 can adopt preboiler or Electric heating appliance etc.Preferably, described Preheating unit 2 is a preboiler.More preferably, preboiler is the water pipe vertical boiler.Preboiler more is applicable to large-scale water circulation system, and the efficiency of heating surface is higher, and energy consumption and cost are lower, uses general more, extensively.
Owing to circulating a large amount of hot water in this pre-heating system, thereby can produce a large amount of heat steams, if the untimely discharge of these hot steams can make that the pre-heating system pressure inside is too high.Preferably, this pre-heating system also comprises swelling water tank 7, and this swelling water tank 7 is connected to described first heating equipment 3 by pipeline.Swelling water tank 7 operated by rotary motion are at roof, and a large amount of steam that first heating equipment 3 produces are discharged by the air hole at swelling water tank top in pipeline flow to swelling water tank again, make the interior pressure of pre-heating system keep stable.
Because when diesel engine of diesel locomotive startup, shutdown, application of load or shutdown are incubated; temperature to machine oil, fuel oil and the cooling water of diesel engine all has certain requirement; and the fuel oil of internal-combustion engine needs different temperature with machine oil under different operating modes, so adopt different heating equipments that it is heated.As shown in Figure 2, preferably, the pre-heating system of second mode of execution of the present utility model also comprises second heating equipment 8 and second valve 9 that links to each other by pipeline, described second heating equipment 8 is connected with described Preheating unit 2 by pipeline, described second valve 9 is connected with described water pump 1 by pipeline, and described water pump 1, Preheating unit 2, second heating equipment 8 and second valve 9 constitute second circulation waterway.First circulation waterway is in parallel with second circulation waterway, and both can independently work respectively, also can work simultaneously.Wherein, first heating equipment 3 can be set to high-temperature heating equipment, and its heating-up temperature is higher, utilizes it that the fuel oil of internal-combustion engine is carried out the high temperature heating, makes its easy burning; Second heating equipment 8 can be set to low-temperature heating device, and its heating-up temperature is lower, utilizes it that the machine oil of internal-combustion engine is heated, and makes it be beneficial to lubricating maintenance.
Preferably, described swelling water tank 7 also is connected to described second heating equipment 8 by pipeline.A large amount of steam that second heating equipment 8 produces are discharged by the air hole at swelling water tank top in pipeline flow to swelling water tank again, make the interior pressure of pre-heating system keep stable.
Convenience for operations such as the control of pre-heating system and maintenance, preferably, described pre-heating system also comprises the 3rd valve 10 and the 4th valve 11, described the 3rd valve 10 is arranged between described preboiler 7 and described first heating equipment 10, and described the 4th valve 11 is arranged between described preboiler 7 and described second heating equipment 8.When preboiler inlet water temperature degree or outlet coolant-temperature gage reach 60 ℃ or 80 ℃ respectively, close first valve 4, second valve 9, the 3rd valve 10 and the 4th valve 11, water in the pre-heating system no longer flows in first heating equipment 3 and second heating equipment 8, thereby stops fuel oil or machine oil etc. is heated.Simultaneously, can open the blowdown valve blowdown of preboiler, under the situation of other parts that do not influence this pre-heating system, both can realize controllability like this, can advance the care and maintenance of shape parts again heating operation.
The various valves of on-off function of realizing all can apply in this pre-heating system, for example gate valve, ball valve, butterfly valve etc., to realize the function of this pre-heating system suitably, preferably, described first valve 4, second valve 9, the 3rd valve 10, the 4th valve 11 and water-feeding valve 6 are stop valve.Stop valve structure is simple, simple installation, and can easily connect or the pipeline in this pre-heating system, realize its function.Simultaneously, easy to operate, cost is lower.
Below describe preferred implementation of the present utility model in conjunction with the accompanying drawings in detail; but; the utility model is not limited to the detail in the above-mentioned mode of execution; in technical conceive scope of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
Need to prove in addition, each concrete technical characteristics described in above-mentioned embodiment under reconcilable situation, can make up by any suitable manner, for fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible compound modes.
In addition, also can carry out combination in any between the various mode of execution of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
