SU12632A1 - A locomotive designed to operate primarily in areas of poor water and mountainous - Google Patents

Description

The invention relates to locomotives intended for operation mainly in areas that are mountainous and poor in water, and equipped with a heating machine with a surface condenser or an internal combustion engine with a cooling water cooler. In order to obtain a sufficient cooling effect and a minimal weight and volume of the cooling device, as well as a relatively small water flow, the proposed locomotive and the surface of the condenser (or the cooler) are calculated sufficiently for normal load of the machine with air cooling. When the normal load is exceeded, water is introduced into the notes of cooling air through the series, increasing the cooling effect of the condenser (or cooler),

In fact, the nominal in FIG. The first locomotive has a waste load of the steam engine 1 and the pipe 2 to the surface condenser placed in the rear part of the locomotive, consisting of two sides of the ion boxes 3, 4 and the battery of tubes 5 connecting them.

A pipe of 2 m of this nara is in connection with the steam box 3, so that the crush passes through the battery of tubes 5, as indicated by the arrow in FIG. 2. At the upper rear end of the box 4, a water jet air pump 6 is installed, while the condensation water escapes into a separate iodine box by a collecting tank 7, from which it is removed by a condenser pump.

The tube from the steam box 3 also leads to this tank. Under the condenser 8, 4 and o there is a reservoir 9 for cooling water connected to tubes arranged one above the other in the frontal frontal part of the condenser with rearward spraying sockets 10. Water is not iodine to the latter the water pump shown in the drawing, which can simultaneously drive the pump 6. In front of the tubes with nozzles 10, there are two fans 11 that suck cooling air (for example, from the side) and are driven by a motor 12. Pressure the nozzles of the fans 11 are directly attached to the front frontal wall of the condenser, which has an exhaust shaft 13 in its rear frontal wall.

The cooling surfaces of the condenser 3, 4, 5 are dimensioned in such a way that they are sufficient for condensation at the normal power of the steam engine 1, when only air blown by the fan 11 through the battery of tubes 5 and receiving a relatively high speed is used for cooling.

When the normal power is exceeded, in essence, when the machine reaches its maximum power, water cooling is turned on; Water over the entire height of the battery of the tubes 5 flows out of the soiel 10 and passes the condenser in the same direction as the cooling air. The flow rate of the injected water is designed just enough so that the water caught by the flow of cooling air, hitting the steam lines, mutually displaced tubes o, is finely sprayed and gradually all the way, up to the exhaust shaft 13, completely evaporated, only air saturated with steam escapes from this shaft. Thus, the tubes 5, which should give away the tenlo necessary for evaporation of the injected water, are strongly cooled, so that a comparatively small surface of the condenser 3, 4, 5 should be sufficient to condense the amount of steam that corresponds to the maximum power of the machine 1.

FIG. 4-7 depict a locomotive driven by an internal combustion engine. The internal combustion engine 15, which is mounted for driving the locomotive 14, drives the generator 1 (1, which is excited by the driver 17). The current of the generator 16 drives the electric motors 18 acting on the axis 19. The engine cylinders are cooled, as usual, with water, which In turn, it is cooled in the cooler. The latter consists of two groups of cooling tubes 20, 22 and is placed at one end of locomotive 14. Reverse cooling water flows from engine cylinders 15 through pipeline 23 to each group of tubes 20, 22 and raschaets back to the cylinders turn the conduit 24.

With an average locomotive power

14, i.e. when traveling mainly in flat terrain, the cooling of the tubes 20, 22 is performed exclusively by air, using a fan 26 installed over the battery groups of cooling tubes 20, 22 and driven by the motor 25. The cooling tubes are measured, therefore, so that average engine power

15, coming from the cylinders through the pipe 23, the hot water would be sufficiently cooled when passing through the cooler so as to serve again to cool the cylinders, flowing to them through the pipeline 24.

In order to temporarily increase the power of the locomotive 14 (for example, when approaching the track) to have sufficient reverse cooling of water to cool the cylinders of the engine 15, a water tank 27 is installed on the locomotive (FIG. 4) connected by pipeline 28 to the suction port of the pump 29 driven an electric motor 34. The pump outlet branch pipe 29 is connected by a pipe 30 to a horizontal distribution pipe 31, which extends over

tubes 20, 22. Distribution pipes 32 branch off from the distribution pipe in front of the outer rows of battery tubes 20, 22. Vertical distribution pipes are interconnected by spray pipes having a large number of nozzles 33.

If the air cooling of the tubes 20, 22 is insufficient, by starting the pump -29 into the pump, water is directed through the nozzles 33 of the spray tubes to the tube battery 20, 22. Due to the evaporation of water, the cooling is greatly enhanced, although only a fraction of the pipes are sprayed with water.

Since the size of the cooling tubes 20, 22 should be calculated only by the average power of the locomotive 14 with air cooling, the cooler device will be relatively small and of small length. In addition, when driving in a flat manner with an average power, water will not be consumed at all, which is essential for areas that are poor in water. Then the locomotive can operate during the cold season without recourse to water cooling. Only with a temporary maximum locomotive mop at a very high external temperature, will it be necessary to turn to the aid of water cooling.

The subject of the patent.

Locomotive designed mainly for work in areas of poor water and mountainous, with a steam engine with a surface condenser or with an internal combustion engine with a cooler of warm cooling water, characterized by the use of nozzles 10 (Fig. 1-3) or 83 (Fig. 4-7) through which, when the normal load of the machine is exceeded, water is introduced into the cooling air flow in order to increase the cooling effect (Figures 1-3 of the surface of the condenser or cooler, calculated just enough for the normal load of the machine when cooled enii air (FIG. 4-7).
