Description
Technical field
The present invention relates to the preheating pre-lubrication system of a kind of diesel engine before startup, be used to prevent that diesel engine lacks the resistance of start that starts, can reduce diesel engine under the lubricated oil condition of preheating with oil sump under the state of dry friction (lubricated as yet), prolong the working life of diesel engine.
Background technique
Present diesel engine all makes electricity consumption start, even start diesel engine with motor.Yet diesel engine is not before starting, and owing to leaving standstill of regular period, the basic upper reaches oil return of the lubricant oil of each lubricant housings drain pan (or fuel reserve tank) is also just said, this moment, each friction pair of diesel engine was in dry condition basically.Simultaneously, lubricant oil in the diesel engine oil sump can lose flowability owing to temperature is on the low side, when diesel engine starts, generally enter tens seconds to twenties seconds time of lubricating status needs even longer, and the wear extent of bringing to diesel engine during this period of time is often also many a Working day than the diesel engine proper functioning from dry condition.
In order to prevent that the method that the diesel engine dry friction starts from being: 1. give the oil sump heating of diesel engine, for example with burning with the mode of external heat; 2. with the instrument of a kind of being called " handle ",, make its main friction pairs be re-used electric the startup, can prolong greatly the working life of diesel engine like this by after tentatively lubricated earlier with several circles of the artificial rotation of diesel engine.The labor intensity of this practice is very big, must be finished by the driver who was subjected to specialized training, otherwise the accident that crank is hit the person can occur.Under diesel engine and scientific and technical situation about popularizing, people constantly pursue safe, comfortable, generous and attractive in appearance, use the notion of crank larry to lose.At present, especially in the winter of the northern area of China, diesel engine will increase the flowability of lubricant oil in the oil sump by the mode of external heat before startup, and its efficient is low, poor stability.Also ignored and directly make electricity consumption start the wearing and tearing that diesel engine is brought by the user.
Summary of the invention
At above-mentioned problems of the prior art and defective, purpose of the present invention is providing a kind of startup preheating pre-lubrication system of diesel engine, this system can be to the also auxiliary preheating of each friction pair pressure lubrication of diesel engine in the time of short duration before diesel engine starts, diesel engine is started under good lubricating status, reduce the difficulty of diesel engine winter starting, prolong the working life of diesel engine.
Realize that the technological scheme that the foregoing invention purpose is adopted is: a kind of startup preheating pre-lubrication system of diesel engine, comprise main oil gallery, preheating oil-feed sucker I, motor-driven oil pump J, described preheating oil-feed sucker I places in the fuel tank of motor, main oil gallery is connected with motor-driven oil pump J oil pipe, motor-driven oil pump J is connected with preheating oil-feed sucker I oil pipe, it is characterized in that, between main oil gallery and motor-driven oil pump J, lubricated safety check is installed, preheating pre-lubrication system in parallel between lubricated safety check and main oil gallery, described preheating pre-lubrication system is by the preheating safety check, electric oil pump D and preheating oil-feed sucker II constitute, described preheating oil-feed sucker II places in the engine oil tank, be connected with electric oil pump D oil pipe, electric oil pump D is connected with preheating safety check oil pipe, and the preheating safety check is connected with the main oil gallery oil pipe; The filter screen of preheating oil-feed sucker II and the preheating oil-feed sucker cavity electric heating wire that all distributing;
Electric heating wire is all distributing on filter screen that lubricates oil-feed sucker I and cavity.
Be installed in the electric heating wire one end ground connection among preheating oil-feed sucker I and the preheating oil-feed sucker II, the other end is connected with an end of preheating pre-lubrication control switch, one end ground connection of the motor winding of motor-driven oil pump J and electric oil pump D, the other end is connected with an end of preheating pre-lubrication control switch, and the other end of preheating pre-lubrication control switch is connected with power supply.
Electric heating wire is evenly distributed on the cavity of preheating oil-feed sucker filter screen and preheating oil-feed sucker, and there is the oil resistant insulating material electric heating wire outside.
The working principle of the startup preheating pre-lubrication system of diesel engine of the present invention:
Lubricant oil is heated when preheating oil-feed sucker II, electric oil pump D will heat later lubricant oil and send into the motor main oil gallery with certain pressure through preheating safety check II, at this moment, lubricated safety check I closes, and the flow of lubricant of heating is postbacked in the motivation fuel tank.After engine start, close the startup pre-heating and pre-lubricating system, at this moment, lubricant oil enters motor-driven oil pump J from lubricated oil-feed sucker I and enters the motor main oil gallery through lubricated safety check I motor is lubricated, and preheating safety check II closes.
Compared with prior art, beneficial effect of the present invention is, directly starts diesel engine and can not make diesel engine suffer dry friction under not needing with the situation of crank larry, thereby improve the starting condition of diesel engine, prolongs the life-span of diesel engine.
