New work engine according to the present invention can be manufactured shortlyer when saving Sealing.This is particularly advantageous for the less marine engine of the free space above the motor of place under repair or maintenance work.If piston rod is made the form of several parts,, also can realize dismounting, installation or the replacing of piston rod even the free space height more than the motor is very little so.
Have the piston diesel engine of mobile cylinder sleeve therein, comprise a slide plate, its constitutes a guiding valve near the lower end of cylinder sleeve and with cylinder sleeve.When piston motion during to lower dead centre, slide plate moves away from cylinder sleeve, forms an annular opening between cylinder sleeve and slide plate, and promptly the scavenging gap is used for carrying scavenging air in cylinder.When piston when the upper dead center direction is moved, the scavenging gap is closed once more.The new structure of this diesel engine is specially adapted to the large-sized low-speed two-stroke diesel engine with long stroke as steamer or generating field.In this new structure, can omit the Sealing between engine air, make the motor height reduce.
The present invention will be described in more detail hereinafter with reference to the signal accompanying drawing, represented the existing design of diesel engine and the preferred embodiments of the invention in the accompanying drawing.Shown in the figure be:
Fig. 1 is the constructed profile map of the motor of existing design, and this motor has the scavenging gap in the bottom of cylinder sleeve, and has Sealing;
Fig. 2 to 4 is the constructed profile map of new work engine, makes an explanation according to the mode of operation, operation and the running of new work engine of the present invention mode by the various diverse locations of piston in the cylinder and slide plate.
In the diesel engine that has the crosshead (not shown) as shown in Figure 1 according to existing traditional design, piston 10 moves in cylinder sleeve 11.The part bottom of cylinder sleeve 11 has scavenging port 110, and when piston was positioned at lower dead centre, piston 10 did not cover this scavenging port 110.Then scavenging air is from annulus 110 ' inflow firing chamber.Be positioned at the annulus 110 of piston below 10 ' a part by 110 " sealing between Sealing 12 and crankcase space or engine air.Piston rod 13 between piston and crosshead (not shown) moves in Sealing 12.
Diesel engine shown in Fig. 2 to 4 has the crosshead (not shown), and this diesel engine designs according to the present invention.Lower area at cylinder sleeve 21 does not have scavenging port.But a scavenging slide plate or a sliding element 24 that links to each other with the bottom of cylinder sleeve 21 is arranged, and it moves up and down along with the motion of piston 20.In this course, close the scavenging air cylinder sleeve of flowing through, cylinder space 22 and firing chamber when opening during scavenging gap 210 between cylinder sleeve 21 and slide plate 24.
Guiding element 2124 (only shown in Figure 4) can be between cylinder sleeve 21 and slide plate 24, and as the guiding element and the supporting member of piston ring 205.Herein, guiding element 2124 can be fixedly mounted on the cylinder sleeve 21 as shown in Figure 4; Perhaps guiding element 2124 can be installed on the slide plate 24 and participate in its to-and-fro motion.
An annular piston skirt 201 is installed on the piston 20.The piston 20 that has piston skirt 201 links to each other with piston rod 23.Cold oil is pressed into the inside of piston 20 by passage 230.In the cooling hole 203 of nozzle 202 with fluid injection into pistion 20 bottoms.In new work engine according to the present invention, might cold oil be led postbacking in the motivation space by draining passage 204, rather than for example, with the second channel of piston rod return flow line as existing designed engines cooling oil.In Fig. 2, in Fig. 3 and 4, the design of this draining passage 204 is different on the other hand on the one hand.
Motion and manner of execution with reference to 2 to 4 pairs of slide plates 24 of accompanying drawing make an explanation, and have schematically described among the figure according to a kind of novel diesel machine of the present invention.Suppose that piston 20 moves downward from Fig. 2 to Fig. 4, perhaps on the contrary, moves upward from Fig. 4 to Fig. 2.
The principles described herein have been implemented following thought: the piston rod seal with in slide plate 24 movably rather than two stroke crosshead engines seals scavenging air working room and crankcase space.Existing design has scavenging port 10 (Fig. 1) in cylinder sleeve 11 lower ends, and in contrast, the scavenging slide plate 24 of new work engine, i.e. and the effect of scavenging port and rod seal part has been played with the motion of piston 20 in cylinder sleeve 21 extension, bottom movably.
Can be positioned at the lower end of cylinder sleeve with respect to the scavenging slide plate 24 that casing longitudinal axis moves.Slide plate 24 bears the pressure of air cushion 209, air cushion 209 form towards or against the annular working chamber of cylinder sleeve 21 lower ends.
If control edge 206 in the bottom of piston 20 is towards opposite edges 241 motions of slide plate, 24 on slide plate can begin gradually with piston 20 motions so.Slide plate 24 leaves cylinder sleeve 21 with piston 20 and moves downward.One annular gap 210 is opened between cylinder sleeve 21 and the slide plate 24, and scavenging air (along the direction of arrow) flows into cylinder space 22, i.e. firing chamber by it from the scavenging air working room.Cross-over connection can be carried out by guide bridge 2124 in the annular space, and it can prevent that piston ring 205 from bending in annular space 210.If do not lead bridge 2124, had only so when air cushion 209 lost efficacy, piston ring 205 just may bending enter the annular space.
The scavenging air working room 211 that wherein has scavenging air pressure is the sealing in cabin with respect to the crankcase space with atmospheric pressure, is to realize by the piston 20 that is positioned at slide plate 24 zones in scavenging process.
If piston 20 is once more to the upper dead center motion, the slide plate 24 that is driven by air cushion 206 just also seals scavenging gap 210 once more with piston 20 motions so.When piston 20 continued upwards dead point motion in cylinder sleeve 21, slide plate 24 was decelerated buffering and leans against on the bottom of cylinder sleeve 21.The annular space 210 of scavenging air thereby closed once more.Scavenging air working room 211 remains and the crank box space, i.e. the motor spatial separation.
In the embodiment shown, slide plate 24 is driven with piston 20 motions by air cushion 209.Yet slide plate 24 also can be driven by the fluid pressure drive device (not shown).
Hereinafter, will the acceleration and the moderating process of the slide plate 24 that driven by piston 20 be described in detail.When the lubricant oil in the dampening chamber 207 and the scavenging air that may exist passed the gap and overflow from annulus 207, slide plate 24 accelerated to the speed of piston 20.
In closing closed procedure, slide plate is reduced to the moderating process of the permissible velocity limit of cylinder sleeve 21 upper slides 24 from the speed of piston, is after annular dampening chamber 243 has been closed at edge 242, finishes under the help that is full of compressed-air actuated dampening chamber 243.
Can lay an adjustable annular metal guide plate in the upstream in the scavenging gap 210 that has vertical guiding net.Thereby rotation or eddy current that corresponding serviceability produces can be delivered in the scavenging air that flows into cylinder space 22.
The lubricant oil that is used to cool off is transported to working piston 20 by piston rod 23 from crosshead.Cooling oil is return piston bar 23 no longer, leaves piston 20 but pass passage 204.
Cylinder running surface thereby lubricated oily complete wetting, lubricant oil flows back to engine crankcase along the inwall of cylinder sleeve 21 and slide plate 24.Lubricant oil flows out with the air that is arranged in the dampening chamber that is in closed state at that time 207 of piston skirt below 201, has formed one damping mixed solution slip over the opposite edges 241 of slide plate 204 at the control edge 206 of piston support ring 208 after.Piston skirt 201 serves as the centring element between piston 20 and the piston support ring 208, and has a scraper ring on it.
After removing rod seal part 12 (Fig. 1), can make the engine structure height reduce 30% of about engine cylinder hole dimension, and stroke-bore ratio is 4: 1, other size constancies (length of connecting rod relatively).After dispensing the scavenging air seam, can make the length of cylinder sleeve 21 reduce 85% of about casing bore.
Connection screw thread between piston rod 23 and the piston support ring 208 is easy to get at from crankcase one side.This connection can be released carrying out maintenance work, thereby avoided piston rod is removed.Thereby the dismounting of piston height can reduce the length of about piston rod.
Saved inner lubricant oil spill pipe and also simplified the structure of piston rod 23, this bar also can be made of many parts, has flange to connect between the part.
At last, can be directly with different made cylinder sleeves 21 and slide plate 24.Thereby for example, slide plate 24 can be made with the material of special resistance to chemical corrosion acid etching, the sulfuric acid that overflows such as the colder part from the bottom.Although cylinder sleeve 21 is described as a discrete parts, cylinder sleeve also can be the part of cluster engine naturally.When mentioning the upper and lower that links to each other with cylinder sleeve 21 or piston 20, the upper dead center of piston 20 is meant superposed stroke dead point, the lower dead centre of piston 20 is meant the stroke dead point that is positioned at the bottom, and this is consistent with the structure of motor custom, with the actual direction of cylinder be separate.The present invention is applicable to motor and the irrelevant situation of number of cylinders.
In an illustrated embodiment, shown annular opening, promptly there is the planar boundary surface annular space 210 on slide plate 24 and cylinder sleeve 21.Yet, the separation surfaces between cylinder sleeve 21 and the slide plate 24 on the border also can, for example be corrugated or flexuose.Can imagine that similarly separation surfaces can be designed to diametrically as stepped or corrugated.
