Abstract
The utility model relates to a generating unit with a liquid preheating device, which comprises a liquid cooled engine (1), an air cooled generator (2), a liquid cooled radiator (3), a liquid fuel heater (4) and an engine oil heater (5). The generating unit with a liquid preheating device is characterized in that a water outlet of the liquid cooled engine (1) is connected with a water inlet of the liquid cooled radiator (3) via a connecting pipe (6), a water outlet of the liquid cooled radiator (3) is connected with a water inlet of the liquid fuel heater (4) via a connecting pipe (7), a water outlet of the liquid fuel heater (4) is connected with a water inlet of a liquid cooled engine (1) via a connecting pipe (8) and simultaneously is connected with a water inlet of the engine oil heater (5) via the connecting pipe (8), and a water outlet of the engine oil heater (5) is connected with a water return hole of the liquid fuel heater (4) via a connecting pipe (9). The engine is heated by the liquid fuel heater and the generating unit is preheated by external heat source equipment, so that the generating unit can be started and operated in a low-temperature environment reliably.
Description
Technical field
The utility model belongs to the generator set technical field, relates in particular to a kind of generator set that uses under low temperature environment.
Background technique
Traditional oil-electric engine group is normally carried out preheating with engine charge, the thermal source that adopts is for starting the electric energy of storage battery, owing to be under low temperature environment, to use, the energy of storage battery can not play a role under cryogenic conditions fully, use simultaneously as startup and preheating, consumed power is bigger, starts very difficult, especially using in the environment below-40 ℃, starting the difficulty more that becomes.
Summary of the invention
The purpose of this utility model provides the auxiliary Preheating unit of a kind of generator set simple in structure, that pre-heat effect is good.Realize that the technological scheme that the purpose of this utility model is taked is: the utility model includes liquid-cooled engine, air-cooled generator, liquid cooling heat radiator, liquid oil heater and lube oil heater, connect together with pipeline, circulate in the liquid line of motor and liquid cooling fuel heater by cooling liquid, the heat that adopts electric ignition that fuel oil is lighted the back generation by liquid oil heater during low temperature heats cooling liquid, heat is brought in the cooling water channel and machine oil groove of motor by the cooling liquid after the heating again, through heated engine body and machine oil after the exchange heat, the motor after being heated is easy to start and operation.Its annexation is such: the water outlet of liquid-cooled engine connects the water intake of the liquid cold-hot machine that looses through connecting tube, the water outlet of liquid cooling heat radiator is connected with the liquid oil heater water intake through connecting tube, the liquid oil heater water outlet is connected with the water intake of motor through connecting tube, be connected with the water intake of lube oil heater simultaneously, the water outlet of lube oil heater joins through the backwater mouth of connecting tube and liquid oil heater.
The utility model heats motor with liquid oil heater, reach motor is carried out the preheating purpose, by the external heat source equipment generator set is implemented preheating, make generator set under low temperature environment, start operation reliable guarantee has been arranged, this scheme pre-heat effect is remarkable, is specially adapted to the field that power station etc. has the low temperature environment usage requirement.
