Abstract
The utility model relates to the field of diesel engine lubricating technology of a mining heavy-duty truck, in particular to a diesel-engine accumulator-type preoiler for a mining heavy-duty truck, which is characterized in that a diesel-engine accumulator-type preoiler is connected in parallel between a main oil duct of a diesel engine of the mining heavy-duty track and all friction surfaces of a rotating mechanism, the diesel-engine accumulator-type preoiler comprises a main checkvalve connected with the main oil duct, an accumulator connected with the main checkvalve, a power switch connected with the accumulator, and an electromagnetic valve connected with the power switch. The utility model has the advantages that since the structure is adopted, the accumulator is used to store energy for an engine-lubricating system and provide pre-lubrication for the diesel engine before startup, the unlubricated-friction state and the partial friction sate of the friction surfaces of the rotating mechanism can be prevented during the startup of the engine, the abrasion of the engine is reduced, and the service life of the diesel engine is prolonged.
Description
Technical field
The utility model relates to mining heavy-duty car diesel engine lubrication technical field, particularly a kind of mining heavy-duty car diesel engine energy storage type pre-lubrication device.
Background technique
What the You Nite-Rui Ge MT3600 type electric wheel dump truck that the load-carrying of metallurgical mine use now is 154 tons and the motor of You Ke Reed R170 type electric wheel dump truck used is the KTA3607 diesel engine that Cummins Corp produces.Engine lubrication system does not have the design and installation pre-lubrication device.During vehicle launch, engine rotation drives oil pump pump oil, for lubrication system provides pressure oil lubricated, so when just starting, each friction surface of engine rotation mechanism can not get oil lubricating, is in dry friction and half Frotteurism, causes the wear of diesel engines aggravation, evidence engine start wear extent once, the 4-8 of wear extent doubly when being normal engine work.
Summary of the invention
The purpose of this utility model is to provide a kind of mining heavy-duty car diesel engine energy storage type pre-lubrication device, with accumulator is the engine lubrication system stored energy, for the diesel engine prestart provides pre-lubrication, when preventing engine start, the rotating mechanism friction surface is in dry friction and half Frotteurism, reduce the wearing and tearing of motor, prolong the working life of diesel engine.
The purpose of this utility model realizes by following technical proposals:
Mining heavy-duty car diesel engine energy storage type pre-lubrication device of the present utility model, it is characterized in that diesel engine energy storage type pre-lubrication device in parallel between the main oil gallery of described mining heavy-duty car diesel engine and each friction surface of rotating mechanism, this diesel engine energy storage type pre-lubrication device is by the main one-way valve that is connected with main oil gallery, the accumulator that main therewith one-way valve is connected, the power switch that is connected of accumulator therewith, the solenoid valve that is connected of power switch is formed therewith.
The utility model has the advantages that: owing to adopted said structure, with accumulator is the engine lubrication system stored energy, for the diesel engine prestart provides pre-lubrication, when preventing engine start, the rotating mechanism friction surface is in dry friction and half Frotteurism, reduce the wearing and tearing of motor, prolong the working life of diesel engine.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, mining heavy-duty car diesel engine energy storage type pre-lubrication device of the present utility model, it is characterized in that diesel engine energy storage type pre-lubrication device in parallel between the main oil gallery 3 of described mining heavy-duty car diesel engine and each friction surface 8 of rotating mechanism, this diesel engine energy storage type pre-lubrication device is by the main one-way valve 4 that is connected with main oil gallery 3, the accumulator 5 that main therewith one-way valve 4 is connected, the power switch 6 that is connected of accumulator 5 therewith, the solenoid valve 7 that is connected of power switch 6 is formed therewith.
Before engine start, earlier power switch 6 is connected circuit, this moment, one-way valve 4 was closed, and solenoid valve 7 gets electric oil circuit conducting, and the pressure oil of accumulator 5 enters motor and arrives each friction surface 8 of rotating mechanism, reaches prelubricated purpose.After engine start, power switch 6 disconnecting circuits, solenoid valve 7 cuts out, and disconnects oil circuit, and oil pump 2 pumps into accumulator 5 with the machine oil of oil pan 1 by main oil gallery 3, one-way valve 4, is the pre-lubrication stored energy of next prestart motor.
This device is fit to various mining full-sized car engine lubrication systems to be used.Store the lubrication system energy by accumulator, by the power switch control electromagnetic valve, opened oil circuit before next engine start, the pressure oil of accumulator enters motor and arrives each friction surface of rotating mechanism, reaches prelubricated purpose.Accumulator is the lubrication system stored energy once more after engine start, for starting next time is prepared.
