Abstract
Provided is a radiating system for engines of railway track vehicles, which is provided with a hydraulic pump, a hydraulic motor and a radiator. An engine drives the hydraulic pump, the hydraulic pump drives the hydraulic motor mounted on the radiator, a radiating fan is mounted on an output shaft of the hydraulic motor, an electric proportional valve is integrated on the hydraulic motor and connected with one end of a controller via a circuit, and a sensor is disposed on the radiator and connected with the other end of the controller. The rotation speed of the radiating fan can be adjusted automatically along with temperature change, and the radiating system meets requirements of track vehicles and needs of industrial production in the railway industry.
Description
Technical field
The utility model relates to a kind of railroad track car engine radiation system.
Background technique
At present, the get on the right track engine cooling system of car of railway is that engine speed is directly proportional with radiating fan rotation speed substantially, and irrelevant with the engine cycles water temperature.
The model utility content
The technical problem that the utility model solves: a kind of railroad track car engine radiation system is provided, this radiation system can vary with temperature the rotating speed of automatic adjusting radiation fan, is fit to the radiation system of track vehicle requirement itself and industry production demand for railway systems provide a cover.
The technical solution adopted in the utility model: railroad track car engine radiation system, have oil hydraulic pump, oil hydraulic motor and radiator, Engine driven Hydraulic Pump, hydraulic pump drive is installed in the oil hydraulic motor on the radiator, radiation fan is installed on the hydraulic motor output shaft, is integrated with electric proportional valve on the described oil hydraulic motor, described electric proportional valve connects with controller one end by circuit, described radiator is provided with sensor, and described sensor connects with the controller the other end.
Described sensor is water temperature sensor and air temperature sensor.
The utility model advantage compared with prior art:
1, radiating fan rotation speed is not influenced by engine speed, but regulates the rotating speed of radiation fan automatically according to detected engine water temperature, ambient temperature, reaches the purpose of coupling engine radiating amount;
2, radiation system is provided with the adjustment link, can be set based on the test final pressure flow scope.
Description of drawings
Fig. 1 is the utility model working principle skeleton diagram;
Fig. 2 is the utility model working principle schematic representation.
Embodiment
Below in conjunction with accompanying drawing 1,2 a kind of embodiment of the present utility model is described.
Railroad track car engine radiation system, have oil hydraulic pump 1, oil hydraulic motor 2 and radiator 3, motor 4 drives oil hydraulic pump 1, the oil hydraulic motor 2 of oil hydraulic pump 1 drive installation on radiator 3 installed radiation fan 5 on oil hydraulic motor 2 output shafts, be integrated with electric proportional valve 6 on the oil hydraulic motor 2, electric proportional valve 6 connects with controller 7 one ends by circuit, radiator 3 is provided with sensor 8, and sensor 8 is water temperature sensor 9 and air temperature sensor 10, and sensor 8 connects with controller 7 the other ends; Sensor 8, controller 7, electric proportional valve 6 and oil hydraulic motor 2 are formed the closed loop automatic control system that a cover can be controlled radiation fan 5 rotating speeds automatically according to the water-exit temperature and the ambient temperature of detected motor 4.
The utility model drives oil hydraulic pump 1 by motor 4, radiator 3 is lifted under the vehicle frame by beam, the oil hydraulic motor 2 of charged Proportional valve 6 is installed in and drives radiation fan 5 on the radiator 3, is provided with two mounting holes on the radiator 3, and water temperature sensor 9 and air temperature sensor 10 are housed respectively.
Working principle: the water-exit temperature of motor 4 and ambient temperature have certain normal range (NR), at first set an engine speed point (maximum power point), when engine speed reaches set point or be higher than the set point rotating speed, drive the water-exit temperature and the ambient temperature of the automatic detection of engine 4 of radiation system, when if some temperature reach radiator 3 and open temperature in water-exit temperature and the ambient temperature, radiation fan 5 is opened automatically, and this moment, the rotating speed of radiation fan 5 was lower; When water-exit temperature and ambient temperature all reached radiator 3 and open temperature, radiation fan 5 rotating speeds just can be increased to maximum speed automatically; In the time of under engine speed is operated in set point (maximum power point), radiation system compares detected water-exit temperature and ambient temperature, and proportional radiation fan 5 rotating speeds that allow are worked under maximum speed.
The rotating speed that the utility model can be controlled radiation fan 5 automatically according to the water-exit temperature and the ambient temperature of detected motor 4, thereby control heat dissipating capacity, reach of the heating value automatically requirement of coupling of the heat dissipating capacity of radiator 3, be fit to the radiation system of track vehicle requirement itself and industry production demand for railway systems provide a cover with temperature and motor 4.
