Abstract
The invention relates to a supercharged diesel engine lubricating device which comprises a pre-lubricating oil loop and a main lubricating oil loop. An oil pump capable of operating in two directions replaces a starting oil pump operating in one direction, one end of a check valve is connected onto an output of an oil coarse filter, the other end of the check valve is connected onto the connection point of the bidirectional oil pump and the check valve, and a supercharger lubricating loop is formed. Double lubricating functions are achieved through the bidirectional rotating oil pump, a diesel engine is pre-lubricated, and a heating supercharger is well lubricated and cooled after shutdown, accordingly reliable working of moving parts of the supercharger is ensured, and service life of the supercharger is prolonged.
Description
Technical field
The present invention relates to a kind of supercharged diesel engine lubricating fitting, belong to Diesel Engine Technique Field.
Background technique
The lubricating oil system of diesel engine of diesel locomotive generally only has the Starter oil pump of a single direction rotation, and its major function is carried out pre-lubrication to diesel engine exactly before diesel engine starting.And behind diesel engine stop, be in the pressurized machine of High Rotation Speed owing to there is not lubricating oil in time to cool off, and often can affect the working life of the moving elements such as bearing in the pressurized machine, serious even can damage pressurized machine.
Summary of the invention
Purpose of the present invention overcomes the deficiency of above-mentioned prior art exactly, and a kind of supercharged diesel engine lubricating fitting is provided, the lubrication problem of the moving elements such as bearing behind the solution diesel engine stop in the pressurized machine.
The object of the present invention is achieved like this: a kind of supercharged diesel engine lubricating fitting; comprise pre-lubrication machine oil loop and main lubricating oil loop; pre-lubrication machine oil loop is by oil sump; primary oil filter 4; check valve 8; the Starter oil pump of unidirectional operation; check valve 9 and filter thin oil 3; diesel engine sequentially consists of; main lubricating oil loop is by oil sump; main lubricating oil pump 1; heat exchanger 2; filter thin oil 3; diesel engine sequentially consists of; but it is characterized in that substituting with the oil pump 5 of way traffic the Starter oil pump of unidirectional operation; check valve 7 one is connected to the delivery outlet of primary oil filter 4; the other end is connected to the contact of two-way oil pump 5 and check valve 9, forms by primary oil filter 4; check valve 7; two-way oil pump 5; check valve 10; oil precision filter for turbocharger 6; the pressurized machine that pressurized machine sequentially consists of is shut down the lubricating oil loop.
Adopt the solution of the present invention; oil pump by a bidirectional rotation has realized two cover lubricating functions; not only make diesel engine obtain pre-lubrication; and after shutdown; the pressurized machine of heating has also obtained fine lubrication and cooling; thereby guaranteed the reliable operation of pressurized machine moving element, also prolonged the working life of pressurized machine.
Description of drawings
Fig. 1 is the supercharged diesel engine lubricating fitting principle schematic of the embodiment of the invention.
Embodiment
For the purpose, technological scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technological scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiments.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment who obtains under the creative work prerequisite.
Referring to the supercharged diesel engine lubricating fitting of Fig. 1 present embodiment, comprise pre-lubrication machine oil loop, main lubricating oil loop and pressurized machine shutdown lubricating oil loop.Pre-lubrication machine oil loop sequentially is made of oil sump, primary oil filter 4, check valve 8, two-way oil pump 5, check valve 9 and filter thin oil 3, diesel engine.Main lubricating oil loop sequentially is made of oil sump, main lubricating oil pump 1, heat exchanger 2, filter thin oil 3, diesel engine.Check valve 7 one is connected to the delivery outlet of primary oil filter 4; the other end is connected to the contact of two-way oil pump 5 and check valve 9, forms the pressurized machine that sequentially is made of primary oil filter 4, check valve 7, two-way oil pump 5, check valve 10, oil precision filter for turbocharger 6, pressurized machine and shuts down the lubricating oil loop.
The operation of the supercharged diesel engine lubricating fitting of present embodiment is divided into following 3 stages.
The pre-lubrication stage: before diesel engine starting, draw machine oil by two-way oil pump 5 from oil sump, these machine oil are injected in the Oil gallery system of diesel engine again, make machine oil be full of pipeline, all parts of diesel engine are carried out pre-lubrication.Two-way oil pump 5 rotates in a counter-clockwise direction (motor rotates in a clockwise direction), draw machine oil through check valve 8 from oil sump, pass through again check valve 9 with oil delivery in filter thin oil 3, make oil filter 3 housings be full of machine oil, oil pressure reaches minimum limit value, pre-lubrication will continue 30 minutes, and oil pressure can reach 141KPa.
Main lubrication phase: after diesel engine starting, main lubricating oil pump 1 is drawn machine oil from oil sump, enters diesel engine through lubricating oil heat exchanger 2 and oil filter 3.
Rear lubrication phase: behind diesel engine stop, control two-way oil pump and rotate in a clockwise direction (motor rotates in a counter-clockwise direction), through the oil sump extraction machine oil of check valve 7 from diesel engine, then oil delivery is arrived pressurized machine filter cleaner 6.Machine oil after the filtering enters in two pipelines of both sides pressurized machine, and pressurized machine is lubricated 15 minutes.
It should be noted that at last: above embodiment only in order to technological scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technological scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characteristics wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technological scheme.
