Description

The method and apparatus that is used for lubricated large-scale diesel engine cylinder surfaces
Technical field
The present invention relates to a kind of lubrication system, this lubrication system comprises and is used for lubricated large-scale diesel engine, the especially method and system of marine engine cylinder surfaces, described method and system comprises at least one lubricating fitting, this at least one lubricating fitting has some reciprocating pumps, and these pumps link to each other with one or more lubricating point that separates in being arranged on cylinder sleeve and each pump is supplied with this one or more lubricating point of separating.
Background technique
Traditionally, lubricating fitting is designed to pump assembly, and described pump assembly is mounted to and separately the cylinder connection that is closely related, and links to each other with the supply container of lubricant oil, and the different parts on casing wall links to each other with the lubricating point that is the oil nozzle form.Each pump assembly comprises a plurality of reciprocating pumps, and these pumps are to each lubricating point supplying lubricating oil, and by shared Spin Control axle and the effect cam drive on it.When the rotation of this axle, the cam action with compacting head is on axially movable piston separately, and these pistons are spring biased toward Control Shaft, and therefore piston will move back and forth when axle rotate, with the piston of driving reciprocating pump.
For many years, lubricating fitting is operated under such condition, and promptly the head pressure from reciprocating pump does not need very big.Therefore, under the situation that is not having atomizing, need by link to each other with nozzle, size is that 10 injection or the pumping pressures that cling to are operated.
In recent years, proposed by supercharging atomizer nozzle jet lubrication oil to realize during moving upward at piston that oil mist lubrication improves lubricating efficiency.For guaranteeing that carrying out finer atomization lubricant oil by atomizer nozzle will be applied in very high pressure, for example pressure is up to 100 crust or higher but thus.
Fixing standard is, makes progress between flyback period at engine piston, promptly in compression process, but before ignition subsequent working stroke, lubricant oil is ejected in the cylinder.
Therefore, as in this application, lubricating point comprises oil nozzle and/or supercharging atomizer nozzle.
In two kinds of systems, by coming the drive controlling axle, thus, can provide power to come driven pump with the direct or indirect mechanical coupling of engine crankshaft, and realize simultaneously between the Control Shaft of engine crankshaft and lubricating fitting synchronously.
Pump assembly for example can comprise the box-type devices housing, and connecting tube extends on the lubricating point of correlation engine cylinder from this, and for example number is 6-24.
Traditionally, operate these pistons by the driving cam/rocking arm that runs through on the Control Shaft, the described bent axle that runs through Control Shaft and motor rotates synchronously.Piston is spring biased toward driving cam.Be provided with the limit position that set screw limits associated activation cam.The manually-operable set screw determining each working stroke of piston, and is determined the relevant discharge capacity of each reciprocating pump thus.
In addition, need all the more to adjust easily again flexibly the lubricant oil part of supplying with cylinder for the required at once control of motor according to the engine parameter of various measurements.All these adjustment are preferably central authorities' control.
Because cylinder lubricating oil measures with a part according to the motor revolution, so can only adjust the stroke that dosage changes pump.
System for this purpose is described in for example DK patent application 4998/85.This system utilizes cam disk mechanism to operate, to adjust the stroke of pump according to the load of motor.Changing this dependence can only change this cam disk with the cam disk that has different propagation functions in addition and realize.
Another kind of system also is known, this system comprises the lubricating fitting that adopts the center driven piston, this center driven piston is installed in the housing and is used as in the hole of oil hydraulic cylinder, and drives by the lubricant oil of supplying with in the oil hydraulic cylinder middle hydraulic chamber, and driven plunger is arranged in the oil hydraulic cylinder.Come supplying lubricating oil by control valve, this control valve comprises valve pocket, and this valve pocket can make hydraulic chamber link to each other with the oil extraction pipeline, and this oil extraction pipeline makes lubricant oil turn back to fuel reserve tank/lubricating fitting, perhaps link to each other with pressure piping, this pressure piping on the pressure side links to each other with fuel reserve tank.Hydraulic chamber links to each other with several quantitative cylinders that quantitative piston is housed, so that lubricant oil is transported to each lubricating point.
Quantitatively each in the piston all drives by power piston, so that lubricant oil is partly supplied to each lubricating point.Rely on stroke to determine oily part, the trip is adjusted by the hand adjustment retainer, and this hand adjustment retainer is determined the stroke of power piston, and also determines each working stroke of quantitative piston thus, and the relevant discharge capacity of determining each metering pump thus.
The scheme that has proposed to regulate is the lubricant oil from the particular pump stroke to specific lubricating point partly to be turned back to the lubricating fitting, because the electronic control of this lubricant oil part of formation redirects between lubricating fitting and lubricating point.This system operation performance is satisfactory, but presumable place will avoid bypass guiding lubricant oil to turn back in fuel reserve tank/lubricating fitting in the system.
Aspect traditional cylinder wall lubrication, actually so far accomplish to use simple spring bias voltage one-way valve can sustain the internal pressure of cylinder, but produce higher slightly outer jet pressure.Yet, aspect the supercharging atomized spray, valve system preferably and must under much higher oil pressure, open so that make oil spurts just present the characteristic of supercharging atomized spray from the beginning.Therefore, we mention the pressure reduction factor up to percent hundreds of.
Summary of the invention
The purpose of this invention is to provide a kind of system and method, thus might by algorithm adopt automatic stepless or progressively the stroke of control pump piston to form cylinder lubricated, therefore, lubricant oil needn't by-passing and turn back to realize under the situation of fuel reserve tank/lubricating fitting flexibly central authorities automatically control lubricant oil is supplied to each lubricating point is possible.
This control is electronic type, and can comprise the control of hydraulic system, and this hydraulic system is used for concentrating and automatically adjusts.
According to the present invention, above-mentioned purpose realizes by this method mentioned in the preface, the method is characterized in that, owing to set up the central electronic control of reciprocating pump stroke, the lubricant oil from specific pump stroke to one or more lubricating point partly is conditioned.
System of the present invention is characterised in that this system comprises electronic control unit, and this electronic control unit links to each other with the controlling mechanism (regulating means) of the adjusting device for travel of reciprocating pump, and this controlling mechanism is electronically controlled.
This controlling mechanism can be electronic unit, pneumatic unit or the hydraulic unit that is controlled by an electronic control unit.
Utilize method and system of the present invention, can regulate the lubricant oil part to concentrate according to the different adjustment principle of determining by electronic control with automatic mode, wherein, the lubricant oil part that algorithm can regulate reciprocating pump is discharged.Utilize in the electronic control unit appropriate algorithm a cylinder and/or in different cylinders with random order with alternately to control to each lubricating point fuel feeding be possible.Therefore, reduce the lubricant oil that sprays in a cylinder/a plurality of cylinders and partly become possibility.Can be individually or regulate each lubricating point in groups.
Because therefore the lubricant oil part of one or more lubricating point in the use electronic control is regulated from lubricating fitting to one or more cylinder provides a simple relatively solution.Utilize this solution, can electronically controlled mode realize stepless adjustment stroke and realize in the single pump stroke of lubricating fitting stepless adjustment thus to each cylinder supplying lubricating oil part.
Therefore, it is possible in the pump stroke of the reciprocating pump of lubricating fitting the lubricant oil of one or more lubricating point in all cylinders or part cylinder partly being regulated, and by the pump stroke in lubricating fitting subsequently the lubricant oil of other lubricating point in cylinder is partly regulated downwards.Therefore, in a circulation, can circulate and regulate the fuel feeding of each lubricating point in a cylinder or a plurality of cylinder.
It is lubricated that system of the present invention can be used for traditional lubricated and so-called SIP.In addition, system of the present invention also can be used to regulate the stroke of reciprocating pump, this pump is connected to one or more lubricating point, and no matter this reciprocating pump whether lubricant oil is directly supplied to each lubricating point or whether this reciprocating pump works by some relevant metering pumps.The possibility of advantage of the present invention and saving lubricant oil is no matter how attractive equally lubrication principle is.
Therefore, adopt system of the present invention, reduce amount of restriction in the lubricating point condition of given number and become possibility.Lubricating point number with Flow-rate adjustment possibility depends on how flexible the user requires to regulate.Adopt system of the present invention to guarantee automatic shift between the lubricating point that carries out Flow-rate adjustment.
System of the present invention can be incorporated in the lubricating fitting or installs as independent device, and this self-contained unit is associated with existing or new lubricating fitting.Therefore, the favourable part of system of the present invention is that this system can improve conventional device, always and no matter whether the lubricating fitting of these prior aries has a mode to construct in the above described manner.
Come control flow rate to regulate with electronic control, so that be adjusted to the lubricants capacity of each lubricating point according to actual needs with payload.Basically we can say, by stepless or progressively adjust the stroke that reciprocating pump comes and goes and carry out this adjusting.Realize oil mass adjustment stepless or progressively by the stroke of setting or adjust reciprocating pump in simple mode.By travel settings to 0 (zero) being made lubricated stroke jump.
According to the present invention, electronic control can be programmed.Can mention a kind of lubricating fitting as example, this lubricating fitting is used for supplying with 10 lubricating points.Can realize reducing 10% like this, because lubricating point is skipped in each later circulation.After 10 circulations, each in the lubricating point can be skipped.No matter this how skipping, the system of the application of the invention can finish the lubricated of each cylinder in each circulation.But this lubricated may not occurring on each lubricating point of cylinder.
According to another embodiment, method of the present invention is characterised in that, regulates the lubricant oil part according to the adjusting algorithm of typing, and this adjusting algorithm is contained in the electronic control unit.Standardization program is programmed in the electronic control unit, and perhaps the adjusting option with user's design can be input in the control program.Therefore, simply mode realizes being suitable for different user and/or operates the adjusting that requires.
According to another embodiment, method of the present invention is characterised in that, alternately regulates the lubricant oil part in different cylinders between each lubricating point, and these cylinders lubricate by using one or more lubricating fitting.According to specific embodiment, can use traffic regulate and control one or more lubricating fitting, and in these lubricating fittings each can be used for supplying with the many lubricating points in one or more cylinder.Therefore, the present invention is not limited to each cylinder and uses lubricating fitting and Flow-rate adjustment only to regulate a lubricating fitting.
Compare with not adopting engine lubrication of the present invention, advantageous particularly of the present invention when motor turns round in low-down load range, with only according to the conventional cylinder of engine speed lubricated compare to reach save the lubricant oil oil mass.
According to another embodiment, method of the present invention is characterised in that, this control comprises drive actuator, this actuator is connected on the adjustable retainer of piston stroke, and has ungoverned initial position, the maximum control that is used for lubricant oil is supplied with, and can be infinitely or speed change ground the control of lubricant oil is supplied with the situation of supplying with without any control that reduces to lubricant oil.This is a kind of reliable very simply again embodiment.Actuator can be rotatable or the actuator of translation progressively.Therefore, this actuator can be regulated downwards and to adjusted according to the direction of rotation/translation.
According to another embodiment, method of the present invention is characterised in that, between the lubricated stroke of lubricating fitting, sometime, finish the change of the stroke of reciprocating pump, and the lubricant oil that the preferred origin self-lubricating device of this change is used to finish is controlled the index signal triggering of supplying with.Realize a kind of very simple structure thus.By the index signal that the lubricant oil that is used to complete is supplied with, the stroke adjustment after only need carrying out between the lubricated stroke.For example, when per minute 100 changes, between lubricated stroke, can have 600 milliseconds.Even remove the used time of adjusting device for travel that drives reciprocating pump, it also is sufficient that the above-mentioned time is exchanged the full line journey.
Therefore, adjusting can not rely on the rotating speed of motor and finishes, for example according to coming the index signal of self-lubricating device to finish.For control flow rate is regulated, thereby can use different parameters, for example motor actual load, the signal that comes self-lubricating device, pressure condition, loading condiction, user's special parameter, as flatten analysis result or other parameter.Therefore, Flow-rate adjustment can be according to Principles of Regulation, and for example engine speed (RPM), mean effective pressure (MEP) or engine power (BHP) are controlled.
According to another embodiment, method and system of the present invention is characterised in that pump stroke is used to supply with 1-6 or more lubricating point in the cylinder sleeve.Therefore, this system can be used to regulate the stroke of reciprocating pump, this pump is connected on one or more lubricating point, no matter whether reciprocating pump directly supplies to lubricant oil on the lubricating point like this, perhaps whether reciprocating pump works by a series of relevant metering pumps.
According to another embodiment, system of the present invention is characterised in that, controlling mechanism comprises actuator, this actuator is connected on the adjustable retainer of piston stroke, and have ungoverned initial position, be used for the maximum control supply of lubricant oil and can infinitely or progressively speed change the situation without any the control supply that increases or reduce to lubricant oil be supplied with in the control of lubricant oil.This is a kind of reliable very simply again embodiment.
