Technical field
The utility model relates to the cylinder of diesel engine lubrication system, specifically refers to a kind of two stroke diesel engine reflux valve pulsed electronic control cylinder oil injecting lubricating system.
Background technique
In order to improve performance and to reduce fuel consumption rate, the large ship diesel engine increasing towards stroke of piston, compression ratio is more and more higher, pressure of explosion and the increasing future development of mean effective pressure, in order to keep good lubrication, the consumption rate of cylinder oil obviously increases, therefore how the increase of cylinder oil consumption rate must cause the rising of operating cost, and the consumption rate of less cylinder oil is another important approach that cuts operating costs.The cylinder oiler oiling is divided into mechanical lubricator and the large class of automatically controlled oil gun two, wherein used mechanical type cylinder oiler major part is all that this Jensen Cylinder lubricating of Denmark's Chinese system house produces, the size of mechanical type oil gun oil filling amount and the rotation speed change of main frame are linear, its oil mass is that rotating speed is controlled, the adjusting of oil mass mainly relies on the plunger stroke of each junior unit of manual tune to realize, can not satisfy lubricated and save the demand of cylinder oil.
For automatically controlled oil gun, the electronic timing swirl-spray formula cylinder lubricating system (SIP system) of the HANS JENSEN Lubricators company exploitation of Denmark, changed cylinder in the past and adopted the be periphery conventional lubrication mode of oil of mechanical timer oiling and piston, adopted the electronic timing oiling and rotate the lubricating system of scavenge flow cloth oil phase combination.Man B﹠amp; Alpha ACC (Adaptive Cylinder oil control) the electronic timing cylinder lubricating apparatus of W company exploitation, it is the high-pressure oil pump that a kind of electronic timing sprays, pumping plant provides the cylinder oil (pressure is generally between 4.0-4.5) of high pressure, by the common rail pipe road waiting before each oil gun, then the injection by control unit control cylinder oil.The pulse lubricating oil system of watt Ceylon company (Pulse Lubricating System is called for short PLS).Cylinder lubricating oil is by the dosing pump on lubricated modular unit, by the pressure of servo oil, it flowed to lubrication filler.Lubricated modular unit has electronics integrated monitor function, be provided with two independently pipeline be cylinder lubrication oil pipe line and servo oil pipe line, the operation power of lubricated modular unit is from through the servo oil of high pressure in the post-decompression servo oily common rail system of reduction valve.
Although automatically controlled oil gun slowly becomes the trend of cylinder oiler development from now on due to its numerous advantage, above these electronic control injections systems is mainly used in new ship construction.Because the oil gun on existing boats and ships mainly still adopts the mechanical type oil gun, so the shortcoming such as the transformation of the mechanical injection system that has used for obsolete vessel all exists complex structure, expensive, maintenance expenses is high, and repacking is inconvenient.HANS JENSEN Lubricators company adopts actuating motor can realize that oil filling amount changes with main unit load (or mean effective pressure) on the basis of its mechanical lubricator, but also can't more accurately control the oiling timing with the main frame working conditions change.
Summary of the invention
The objective of the invention is according to the deficiencies in the prior art, provide a kind of simple in structure, with low cost, reliable operation and its oil filling amount (oiling rate) can make with diesel engine condition and cylinder break-in state the automatically controlled oil injecting lubricating of the cylinder system of adaptations.
the technical solution of the utility model is specifically: described a kind of two stroke diesel engine reflux valve pulsed electronic control cylinder oil injecting lubricating system comprises fuel tank and a plurality of mechanical lubricator, the filler opening of each mechanical lubricator is communicated with the oil outlet of fuel tank by oil inlet pipe respectively, oil outlet is connected with respectively several grease guns, it is characterized in that: install a backflow electrically-controlled valve additional between each mechanical lubricator and several grease guns, be provided with oil inlet passage and return-flow system in the backflow electrically-controlled valve, be connected by automatically controlled backflow couple between oil inlet passage and return-flow system, the filler opening of oil inlet passage is communicated with the oil outlet of corresponding mechanical lubricator, oil outlet is communicated with corresponding several grease guns respectively by oil pipe.
The further technological scheme of the utility model: described return-flow system comprises backflow valve pocket, return line, the backflow valve pocket is communicated with return line by refluxing chamber, described automatically controlled backflow couple is arranged in the backflow valve pocket, control being communicated with and closing of oil inlet passage and return line, be separately installed with at the two ends of backflow valve pocket be used to controlling automatically controlled backflow couple unlatching or closing Returnning spring and the electromagnet that is connected between oil inlet passage and backflow valve pocket.
Optimal technical solution of the present utility model: corresponding filler opening and the oil outlet that equates with grease gun quantity that be provided with on the valve body of backflow electrically-controlled valve, form independent oil inlet passage between each filler opening and corresponding oil outlet, be connected by automatically controlled backflow couple between each oil inlet passage and return-flow system.
