Embodiment Construction

[0054] A preferred application example of the system according to the invention is the sliding surfaces of large machines with reciprocating pistons, in particular compressors, air engines, steam engines, diesel engines, gasoline engines, natural gas engines and other working stroke machines, here An example is the cylinder liner of a two-stroke large diesel engine and the sliding surfaces of the pistons running therein. The following example descriptions are based on this engine, but should not be so limited. Normally, however, the relevant engines have as a common feature a lubrication environment for the bearings on the crankshaft, which is separate from the applied system according to the invention. Furthermore, the individual parallel vertical cylinder axes of the cylinders of the engine are generally arranged in a row on a main shaft axis perpendicular thereto. However, the orientation of each cylinder axis and each relative positioning of the respective possible axes o...

Abstract

The invention relates to a system for influencing the sliding properties of a sliding surface of a sliding pair by supplying the sliding surface with a regulating agent, wherein a plurality of different components can be used for producing the regulating agent, which is permanently achieved by Good functioning of the sliding pair, i.e. provided with a dynamic adjustment of the sliding properties of the sliding surfaces, wherein the sliding conditions of the sliding surfaces are continuously monitored and the regulator supplied to the sliding surfaces is optimized according to the current sliding conditions, the All the components of the regulator are delivered individually and metered to the sliding surface and blended there with one another, and the individual components of the regulator are delivered individually at multiple locations that can be selectively activated Carried out, wherein the activation of the individual delivery positions can take place as a function of the sliding situation. The invention also relates to the use of said system.

Description

technical field [0001] The invention relates to a system for influencing the sliding properties of a sliding surface of a sliding pair by supplying the sliding surface with a regulating agent, wherein a plurality of different components can be used for generating the regulating agent. The invention also relates to the use of said system. Background technique [0002] In most applications, an attempt is made to positively influence the sliding behavior by lubricating the sliding surfaces with a suitable lubricant. The present invention is mainly of importance for piston reciprocating machines (such as compressors, air engines, steam engines, internal combustion engines, etc.), mainly for large engines. Thus, for example, in large-piston reciprocating internal combustion engines which are operated with heavy fuel oil which can form acids during combustion, lubricant is supplied to the sliding surfaces formed by the sliding surfaces of the cylinder liners and the pistons movin...
