Definitions
- the invention relates to a method for controlling the supply of lubricants to the cylinder surface of a piston of a reciprocating piston engine, in particular a 2-stroke reciprocating piston engine according to claim 1, and a device for carrying out the method according to claim 11.
- the object of the invention is to provide a method and a device for controlling the supply of lubricants to the cylinder surface of a piston of a reciprocating piston engine, in particular a 2-stroke reciprocating piston engine.
- the object is achieved by:
- the method can be implemented in different ways.
- the embodiment according to claim 5 is particularly preferred, according to which the current passage is observed by utilizing a thermal current generated by different materials between the cylinder and the piston.
- a thermal current occurs even at the smallest micro-friction points between the cylinder wall and the piston - even before there is perceptible frictional damage between the piston and the cylinder surface - and is expressed in an electrical evaluation as a brief, so-called lightning signal. It is advantageous here that contact resistances in the electrical circuit used can be disregarded when evaluating the signals.
- the method can be supported by applying an electrical current generated by a current source or carried out solely by external current.
- Sources of error in the method are the least if the current path through the reciprocating piston engine is as short as possible.
- the circuit is formed via the cylinder wall, the piston and a piston rod, to which a collector is arranged, which is connected to the circuit.
- the collector is preferably formed by a stuffing box which seals the crank chamber against the underside of the piston. This variant is particularly advantageous in the case of large reciprocating piston engines which operate according to the 2-stroke principle.
- the circuit is advantageously connected to the cylinder wall and the crankshaft according to claim 8.
- the interference signals are monitored for exceeding a predefined limit criterion for incipient friction damage and a damage signal is triggered when the limit criterion is exceeded.
- monitoring can be carried out on each cylinder of a multi-cylinder device in order to assign the incipient frictional damage to a corresponding cylinder.
- Figure 1 is a schematic of a reciprocating piston engine in which the piston is provided with a piston rod;
- Figure 2 shows the diagram of a reciprocating piston engine in which the piston is connected to a crankshaft via a connecting rod.
- FIG. 1 shows the typical diagram of a reciprocating piston engine 2, in which a piston 6 can be moved up and down in a cylinder 4.
- the piston 6 is arranged on a piston rod 8 which is slidably mounted in a fixed guide 10.
- the guide 10 is designed as a stuffing box, which forms a gaseous seal between the underside of the piston 6 and a crank chamber 11.
- the lower end of the piston rod 8 is connected to a crankshaft 14 via a coupling member 13 provided with a crosshead 12.
- a circuit 18 in which a line 20 is connected to the wall of the cylinder 4 and a further line 22 is connected to the gland 10 of the piston rod 8, which acts as a collector.
- the gland 10 is electrically isolated from the engine ground.
- the collector is separated by a tes contact element, for example formed by a arranged on the piston rod 8 carbon brush.
- the circuit 18 contains a resistor 24 and, if appropriate, a current source 26. Within the reciprocating piston engine, the circuit runs between the wall of the cylinder 4 and the piston 6 and the piston rod 8 and the guide 10. In parallel with the resistor 24, there is a control unit 28 which changes the current flow between detects the cylinder 4 and the piston 6 via the cylinder running surface 16, which can occur on the cylinder running surface 16 as the lubricant film begins to tear off.
- the control unit 28 is connected via a line 30 to a device 32 for supplying lubricant to the cylinder surface 16 of the piston 6.
- a corresponding lubricant line 34 is connected to the cylinder 4.
- the reciprocating piston engine 2 is expediently operated under continuous load in such a way that the addition of lubricant to the device 2 is gradually reduced until an interference signal occurs in the circuit 18, which indicates that the lubricant film between the piston 6 and the cylinder 4 starts to tear off signaled.
- the control unit 28 then also gradually increases the lubricant supply to the device 32 until the interference signal disappears.
- the amount of lubricant then added is sufficient to operate the reciprocating piston engine without problems. To increase security, this amount can be increased by a security factor of, for example, 5%.
- the quantity of lubricant required is expediently changed periodically in the mentioned Way re-checked. This monitoring and control can be carried out fully automatically using suitable software.
- the exemplary embodiment in FIG. 2 essentially corresponds to the exemplary embodiment in FIG. 1, so that the same reference numerals are used for the same parts.
- the reciprocating piston engine 2a of FIG. 2 has a piston 6a which is connected to a crankshaft 14a via a connecting rod 36.
- the mode of operation corresponds to that of FIG. 1, but the longer current path of the circuit 18a via the connecting rod 36 and the crankshaft 14a contains a greater susceptibility to faults, since several bearing points have to be overcome, which represent additional resistances.
- the interference signals of the current passage are expediently monitored for exceeding a predefined limit criterion, which is characteristic of an incipient drive damage.
- Drive damage can be recognized, among other things, by the fact that an interference signal that has occurred cannot be made to disappear despite an increased supply of lubricant.
- the temporal rate or the form of pulse-like interference signals can be monitored for the exceeding of predefined limit values, particularly those determined in preliminary tests. If the limit criterion is exceeded, a damage signal is triggered, which can be, for example, an optical or acoustic alarm signal or a signal to shut off the engine.
- the monitoring described above is expediently installed on each of the cylinders of a multi-cylinder device, since in this way an incipient frictional damage can already be localized, ie assigned to a specific cylinder.
