Detailed Description
Further advantages and effects of the present utility model will become apparent to those skilled in the art from the disclosure of the present utility model, which is described by the following specific examples.
The utility model provides a low-temperature starting device of a generator set, which is shown in fig. 1 and 2.
The low-temperature starting device of the generator set comprises a water intake 2 and a water return 1 which are arranged on a diesel engine cylinder body, wherein a water jacket heater 3 and at least one group of fuel liquid heaters 4 are also arranged in parallel between the water intake 2 and the water return 1; cold water flowing out from the water intake 2 enters the fuel liquid heater 4 and the water jacket heater 3 respectively through a water inlet pipeline, and then flows into the water return port 1 through a water return pipeline; the inlet of the water inlet pipeline and the inlet of the fuel oil liquid heater and the inlet of the water jacket heater are respectively provided with a one-way valve 5. In this embodiment, two or three sets of fuel liquid heaters 4 are connected in parallel, and a check valve 5 is also provided at the inlet of the corresponding water inlet pipe.
When the cooling device works, cold water from the water intake 2 respectively enters into a parallel pipeline formed by two fuel oil liquid heaters 4 and one water jacket heater 3, hot water heated by the heaters is introduced into the water inlet and return port 1, and the water inlets of the corresponding heaters are provided with one-way valves 5, so that the one-way flow of cooling liquid can be ensured, the formation of a short circuit is avoided, and the formation of a loop between a diesel engine cylinder body and the heater is ensured to realize the circulating heating of the cooling liquid.
In a low-temperature environment, a standby state and a commercial power connection, at the moment, the fuel oil heater does not work, and the water jacket heater 3 is mainly adopted for preheating to maintain the temperature of the cooling liquid in a range where the engine is suitable to work; if the commercial power is abnormal, the water jacket heater 3 cannot work, continuous heat preservation cannot be provided for the generator set, the operation of the fuel liquid heater 4 can be switched, at the moment, the fuel liquid heater 4 performs preheating to maintain the temperature of the cooling liquid in a range where the engine is suitable to work, the generator set can be started at any time immediately, and the generator set can still keep heat preservation continuously when the commercial power is cut off, so that the generator set can work under various working conditions; the oil supply problem of the vehicle-mounted power station with a large inclination angle, particularly the oil supply problem of the flat oil tank, can be met, and work under various working conditions in a field combat environment can be achieved.
