Abstract
The utility model relates to the field of a lubrication system of a diesel engine, in particular to a lubrication system of a minitype single cylinder diesel. The utility model is provided with an engine oil pump and a main oil gallery; an oil inlet end of the engine oil pump is connected with a first class packed bed filter; the utility model also comprises a pressure regulating valve, a second class packed bed filter, a host vitta part and a low oil pressure warning unit, wherein, the second class packed bed filter is communicated with an oil outlet end of the engine oil pump, and the low oil pressure warning unit and the pressure regulating valve are arranged on the main oil gallery. The high pressure lubricating oil is further filtered by a rotary oil filter of the second class packed bed filter device, and is divided into two ways through the main oil gallery, so as to carry out lubrication for a connecting rod bearing shell, a connecting bar neck and a rocker, etc. The lubrication system has the beneficial effects that the cleanliness of the lubricating oil is improved, at the same time, the pressure lubricating oil ensures sufficient oil film strength, thereby being capable of adapting the further strengthening of the diesel engine; a low oil pressure protective device ensures the safety of the work of the diesel engine.
Description
Technical field
The utility model relates to the lubrication system field of diesel engine, especially a kind of lubrication system of small-sized single cylinder diesel engine.
Background technique
The quality of lubricating system of diesel oil engine is most important to guaranteeing whole aircraft reliability, power character, Economy.Small-sized single cylinder diesel engine is simple in structure because of it, adopts the splash lubrication mode mostly, and it stirs lubricant oil by machine internal gear and movement parts rotation, forms oil mist lubrication piston, piston ring and cylinder sleeve; By the food tray that draws on the bent axle, utilize centrifugal action to guide lubricant oil into crank-shaft link neck simultaneously, form film lubrication crank-shaft link neck and connecting rod bearing shell.Air cooler cylinder head valve cage assembly lubricated is to rely on reciprocating motion of the pistons, forms degree of vacuum in the suction tude, lubricant mist in the body is sucked valve cage and realizes; Water cooling unit then is that spiral chute extruding lubricant oil to valve mechanism cover oilhole carries out drop lubrication valve cage assembly when by the external machine oil pipe of main bearing seat camshaft hole camshaft being rotated.
Though above traditional lubrication system can satisfy the lubricating requirement of each friction surface of diesel engine, but the simple advantage of its self structure brings the inadequate natural endowment that is difficult to overcome for the reliability of diesel engine: the first, this lubrication system has only the one-level filter, cleanliness of lubricating oil is poor, silt particle in the foundry goods such as the metal worn particle of movement parts and body, cylinder cap is easy to enter the movement parts friction and pays the surface, cause premature wears such as cylinder sleeve, piston, piston ring, connecting rod bearing shell, crank-shaft link neck, serious meeting causes axis tile, scuffing of cylinder bore; The second, this lubrication system can only adapt to the following lubricated operating conditions of connecting rod bearing shell specific pressure value 35MPa, can not satisfy the needs that diesel engine is further strengthened.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of novel lubrication system is provided, is applied on the small-sized single cylinder diesel engine, overcome the needs that above-mentioned lubrication system cleanliness of lubricating oil is poor, film strength can not satisfy the further reinforcement of diesel engine inadequately.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of lubrication system of small-sized single cylinder diesel engine, have oil pump, main oil gallery, the filler opening of oil pump is connected with the one-level filter cleaner, also comprise pressure regulator valve, secondary filter cleaner, Oil gallery pipe part and low oil pressure alarm, the secondary filter cleaner communicates with the oil pump oil outlet, and described low oil pressure alarm and pressure regulator valve are arranged on the main oil gallery.
Lubricant oil becomes extreme pressure lubricant through the effect of the eccentric rotor of rotor-type oil pump, to reach enough film strengths, satisfies the needs that diesel engine is further strengthened.
When extreme pressure lubricant further cleans through secondary filter rotary mounting engine oil filter, be divided into two-way by main oil gallery, the one tunnel branches to bent axle, and another road branches to cylinder road head.
The beneficial effects of the utility model are, the utility model is set up the secondary filter, has improved the turbidity test of lubricant oil, and simultaneously, pressure lubrication oil has guaranteed enough film strengths, can adapt to the further reinforcement of diesel engine.Low oil pressure protection device has guaranteed the job security of diesel engine.
