Description
Technical field
The invention belongs to technical field of engines, specifically, the present invention relates to a kind of engine lubrication system.
Background technique
So-called lubrication system, refers to and supplies a series of to the general name of grease, oil extraction fat and fixture thereof of oiling agent to lubricant housings.The function of lubrication system carries quantitative clean lubricant oil to the part surface doing relative movement, to realize liquid friction, reduces surface friction drag, alleviate the wearing and tearing of parts, and clean part surface and cool.Along with the development of automobile, engine running speed goes is high, and power per liter is increasing, and therefore the requirement of each friction pair to lubrication system is more and more harsher, ensureing that motor meets the demand of high strength motor, the reliability of engine lubrication system, low cost also to be ensured.
During engine operation, between the relative motion surface (as bent axle and main bearing, piston and cylinder wall, timing gear wheel set, gas distribution system etc.) of driving parts, certainly lead to friction.Friction between metal surface not only can increase the power consumpiton of engine interior, make part time job surface rapid wearing, and due to fricative large calorimetric may cause part time job surface scaling loss, cause motor to operate.For ensureing the work reliably and with long-term of machine, in the process of running, must by lubrication system to these surface lubricant oil that conveying is enough in time.The function of lubricating system is exactly the friction surface continuously clean lubricant oil enough for quantity being transported to whole driving component when engine operation, and oil film is formed between friction surface, realize liquid friction, thus reduction surface friction drag, reduce power consumpiton, alleviate component wear, to reach the object improving engine operation reliability and durability.
After fuel enters engine combustion, successfully make engine running by changing in fuel, but not all merit is all used for driving the running of engine, because the friction in engine between parts can consume the merit that engine produces, and is converted into heat energy.In order to reduce friction to protect motor, a lubrication system must be had to lubricate engine.Lubrication system is made up of oil leab, oil pump, oil filter and connecting base, cooling unit, heating equipment, seal arrangement, damping device, safety installations, alarm etc. usually.
When designing lubrication system, the lubricating requirement of reply machinery each several part is done comprehensively to analyze, to first determine in advance of the system design make with lubricator kind, reduce the classification of oiling agent and lubricating fitting as far as possible, under the good lubrication condition ensureing primary lubricant parts, consider the lubrication of other lubricating points, lubricating quality be ensured.Should make lubrication system both met in equipment operation to lubrication needs, should adapt with the working condition of equipment and Environmental Conditions again, in order to avoid produce unsuitable friction, temperature, noise and too early inefficacy.And, the oil of lubrication system feed should be made to keep clean, prevent the intrusion of extraneous dirt bits etc. from polluting, damaging friction surface, improve the reliability in using.
At present, engine lubrication system design is very old-fashioned and inflexible, particularly along with adding of engine consumption and discharge is tight, more and more higher requirement is proposed to engine lubrication system, under not only requiring that characteristics of compact layout, cost are low, ensureing the prerequisite of motor properties requirement, reduce the oil consumption of motor as far as possible.
Summary of the invention
