Abstract
The utility model relates to a double preheating device of engine cold starting which is characterized in that a set of S-shaped cooling fluid pipelines are connected in the oil sump of the engine; the S-shaped cooling fluid pipelines are of pipe net shape in the oil sump of the engine; at the same time, the oil sump of the engine is connected with the inlet pipe orifice and the outlet pipe orifice of the S-shaped cooling fluid pipelines; and the inlet pipe and the outlet pipe of a cooling fluid heater are respectively provided with a tee interface which is respectively connected with the inlet pipe orifice and the outlet pipe orifice of the oil sump of the engine. The technical effect of the utility model is that: 1, the inferior lubrication problem is solved for the cold-starting of the engine at low temperature; 2, the low temperature starting time of the engine is shortened; 3, the safety is improved and the service life is prolonged when the engine is started at low temperature.
Description
Technical field
The utility model relates to a kind of double preheating device, relates in particular to a kind of double preheating device of engine low-temperature starting-up.
Background technique
Diesel generating set under the cryogenic conditions causes Engine Inlet Temperature to reduce because the ambient environmental conditions temperature is low, makes that air temperature reduces in the cylinder of top dead center, the diesel oil difficulty of catching fire; Yin Wendu such as cylinder cap, cylinder sleeve, piston reduce, and heat output is big, and the air temperature rise in the top dead center cylinder is reduced; Storage battery chemical reaction velocity Yin Wendu reduces and slack-off, and the storage battery capacity is diminished, and Starter power diminishes; Engine oil viscosity becomes big simultaneously, and motor drags resistance and increases, and rotating speed is reduced.
As the diesel generating set that has requirement under cryogenic conditions, to use, generally all take combustion-supporting gas device, cooling liquid heating equipments such as similar air inlet heating device, lube oil heater, air inlet spray ether to wait motor is assisted preheating, solve the cold start problem of motor.And coolant heater is as a kind of comparatively widespread usage low temperature auxiliary starting device, flows through the whole body of cylinder body through the cooling liquid of heating, improves the temperature of cylinder body, makes burning more abundant.But coolant heater can only carry out preheating to engine cylinder-body, lubricant oil in the oil sump of motor is in the cold conditions state always, in case it is poor in the mobile property of the starting moment lubricant oil of motor, even through the coolant heater preheating, equally also can exist because of the lubricant oil property difference that flows and cause phenomenons such as engine scuffing at engine cylinder-body.In order to improve the flowability of lubricant oil, take measures such as lube oil heater, cause the capacity of storage battery to improve greatly, having increased a lot of unnecessary costs increases.
Summary of the invention
The purpose of this utility model has been to provide a kind of double preheating device of engine low-temperature starting-up, and this device has shortened the time of engine low-temperature starting-up, has improved the Security and the working life of engine low-temperature starting-up.
The utility model is achieved like this, it comprises engine cylinder-body, engine sump tank, S shape cooling liquid pipeline, threeway, coolant heater, it is characterized in that engine cylinder-body connects engine sump tank, connect one group of S shape cooling liquid pipeline in the engine sump tank, S shape cooling liquid pipeline is the webmaster state in engine sump tank, S shape cooling liquid pipeline directly contacts with lubricant oil in the engine sump tank, and cooling liquid can only flow in S shape cooling liquid pipeline, the water inlet pipe mouth and the effluent pipe mouth of S shape cooling liquid pipeline are set on the engine sump tank simultaneously, when connecting coolant heater, intake pipe and outlet pipe at coolant heater increase a three-way interface respectively, simultaneously tee union are connected respectively with effluent pipe mouth with the water inlet pipe mouth of engine sump tank.During use, open the water inlet of coolant heater, the ball valve of rising pipe under the cryogenic conditions, start coolant heater, this moment, coolant heater was except heating cooling liquid in the engine cylinder-body, simultaneously by the lubricant oil in the engine sump tank being heated at the S of engine sump tank shape cooling liquid pipeline, make coolant heater reach the effect of two preheatings, obviously improved the low temperature flow of lubricant oil, shortened the starting time of motor under cryogenic conditions, the Security that has improved engine low-temperature starting-up.
Technique effect of the present utility model is: the situation that 1, has solved cold starting poor lubrication under the motor cryogenic conditions; 2, shortened the time of engine low-temperature starting-up; 3, improved the Security of engine low-temperature starting-up and working life etc.
