Abstract
The utility model relates to a multifunctional fuel oil preheating cold starting device consisting of a liquid fuel oil heater, a fuel oil absorption and heating device of the liquid fuel oil heater, an engine, a warm air radiator, a water tank, a fuel oil tank, a control valve, a control switch, a heating pipe and a pipeline. The liquid fuel oil heater absorbs diesel oil from the fuel oil tank through the fuel oil absorption and heating device of the liquid fuel oil heater; a fuel oil absorption end of the fuel oil absorption heating device is provided with a heater; after entering the liquid fuel oil heater, the diesel oil is combusted inside and generates heat to heat engine coolant; water pump forced circulation coolant in a liquid fuel oil heater body circulates in the engine to preheat an engine body; the warm air radiator in a driving cab is connected in parallel with the water cycle of the engine; and a water outlet of the engine and a water outlet of the warm air radiator are connected with a water inlet of the heating pipe in the fuel oil tank through the pipeline. The device is simple in structure, ensures that the engine can be started reliably under a high-cold environment and enhances the driving comfort as well.
Description
Technical field
The utility model belongs to technical field of engineering machinery, is a kind of cold-starting device that is used on the loader.
Background technique
At present, domestic loader cold start-up method mainly contains ether cold start-up and flame preheating cold start-up dual mode.During with the ether cold start-up, engine body itself still is in low-temperature condition with the interior lubricant oil of body, and lubricant oil can not play good lubrication, forms dry friction between piston and the cylinder sleeve, so bigger to the body injury in initial start stage; And flame preheating cold start-up mainly is that the air that gets into motor is carried out preheating, and engine body itself still is in the low state of temperature, and same the existence roughly starts, the shortcoming that wear of diesel engines is strengthened.The temperature that ether cold start-up and flame preheating cold start-up dual mode are suitable for is limited generally about-20 ℃, and in low temperature environment, fuel oil is had relatively high expectations.
Summary of the invention
The utility model purpose provides a kind of multifunctional fuel oil preheating cold-starting device, to overcome ether cold start-up and the flame advanced ignition dual mode shortcoming to motor wearing and tearing aggravation itself and Applicable temperature restriction.Through heating engine body and engine motor oil are rapidly heated with multifunctional fuel oil preheating cold-starting device to the short circle cooling liquid of motor; Motor is easy to just can start; And can not aggravate the wearing and tearing of motor, can satisfy motor and under-40 ℃ rugged environment, start smoothly.Simultaneously cold-starting device can also play the effect that diesel oil and operator cabin are heated, and reduces the requirement of diesel oil and raising driver's travelling comfort.
The utility model solves the technological scheme that its technical problem adopted: multifunctional fuel oil preheating cold-starting device, this device be by liquid oil heater, control switch; Liquid oil heater oil suction heating equipment, motor, warm air radiator; Water tank; Fuel tank, control valve, heating pipe and pipeline are formed.Liquid oil heater is drawn diesel oil through liquid oil heater oil suction heating equipment in fuel tank, the oil absorbing end of liquid oil heater oil suction heating equipment has heater, prevents that the diesel oil wax deposition from causing the fuel heater can't oil suction.Portion's burning within it produced the heat engine coolant after diesel oil got in the liquid oil heater, and the water pump pump circulation cooling liquid of liquid oil heater self circulates in motor, and body is carried out preheating; Whether the warm air radiator in the operator cabin is parallelly connected with the water cycle of motor, can heat operator cabin through liquid oil heater through the control of A control valve; The water outlet of motor and the water outlet of warm air radiator link to each other with the water intake of heating pipe in being installed in fuel tank through pipeline; The after-heat of cooling liquid can heat the diesel oil in the fuel tank; Prevent the diesel oil wax deposition, the water outlet of last heating pipe links to each other with the water intake of fuel heater.Whether control switch controlling liquid fuel heater works.The effect of water tank is the cooling liquid steady flow that guarantees this circulatory system when the warm air radiator that uses separately in the operator cabin.After the engine start and temperature when not needing cold start-up when higher, close the B control valve, cut-off loop.Thereby avoid the cooling liquid of motor directly to postback motivation without radiator heat-dissipation, make engine overheat.
This apparatus structure is simple; Engine start is more reliable under the psychro-environment, does not strengthen the wearing and tearing to motor in the start-up course, uses the requirement of diesel number to reduce down to psychro-environment; The thermal source that can be used as the warm braw of operator cabin simultaneously is the operator cabin heating, improves driver's travelling comfort.
Description of drawings
Fig. 1 is the schematic diagram of the utility model.
Among the figure: 1. liquid oil heater, 2. control switch, 3. water tank, 4.A control valve, 5. motor, 6.B control valve, 7. warm air radiator, 8. heating pipe, 9. liquid oil heater oil suction heating equipment, 10. fuel tank, 11. pipelines.
Embodiment
Among the figure, multifunctional fuel oil preheating cold-starting device, by liquid oil heater, liquid oil heater oil suction heating equipment, motor, warm air radiator, water tank, fuel tank, control valve, control switch, heating pipe and pipeline are formed.Liquid oil heater 1 is drawn diesel oil through liquid oil heater oil suction heating equipment 9 in fuel tank 10, the oil absorbing end of liquid oil heater oil suction heating equipment 9 has heater, prevents that the diesel oil wax deposition from causing the fuel heater can't oil suction.Portion's burning within it produced the heat engine coolant after diesel oil got in the liquid oil heater 1, and the water pump pump circulation cooling liquid of liquid oil heater 1 self circulates in motor 5, and body is carried out preheating; Whether the warm air radiator 7 in the operator cabin is parallelly connected with the water cycle of motor 5, can heat through 1 pair of operator cabin of liquid oil heater through 4 controls of A control valve; The water outlet of the water outlet of motor 5 and warm air radiator 7 links to each other with the water intake of heating pipe 8 in being installed in fuel tank 10 through pipeline 11; The after-heat of cooling liquid can heat the diesel oil in the fuel tank 10; Prevent the diesel oil wax deposition, the water outlet of last heating pipe 8 links to each other with the water intake of fuel heater 1.Whether control switch 2 controlling liquid fuel heaters 1 work.The effect of water tank 3 is the cooling liquid steady flows that guarantee this circulatory system when the warm air radiator 7 that uses separately in the operator cabin.After motor 5 starts and temperature when not needing cold start-up when higher, close B control valve 6, cut-off loop.This device avoids the cooling liquid of motor directly to postback motivation without radiator heat-dissipation, makes engine overheat.Engine start is more reliable under the psychro-environment, does not strengthen the wearing and tearing to motor in the start-up course, uses the requirement of diesel number to reduce down to psychro-environment, and the thermal source that can be used as the warm braw of operator cabin simultaneously is the operator cabin heating, improves driver's travelling comfort.
