Abstract
A system for supplying at least one lubrication point of a machine with lubricating oil includes: a lubricating oil reservoir; a delivery pump; a heat exchanger; a lubrication point; a plurality of lines including a lubricating oil supply line and a lubricating oil return line, the lubrication point being hydraulically connected to the lubricating oil reservoir via the lubricating oil supply line and the lubricating oil return line, a lubricating oil circuit being configured such that the lubricating oil flows through the lubricating oil circuit in one flow direction, the lubricating oil return line including an inlet point which is configured for a protective medium, which is air, being introduced into the lubricating oil return line.
Claims18
A system for supplying at least one lubrication point of a machine with a lubricating oil, the system comprising:
- a lubricating oil reservoir;
- at least one delivery pump;
- a heat exchanger;
- at least one lubrication point;
- a plurality of lines, the lubricating oil reservoir, the at least one delivery pump, the heat exchanger, and the at least one lubrication point being hydraulically connected with one another via the plurality of lines such that the lubricating oil reservoir, the at least one delivery pump, the heat exchanger, the at least one lubrication point, and the plurality of lines form a lubricating oil circuit, the plurality of lines including a lubricating oil supply line and a lubricating oil return line, the at least one lubrication point being hydraulically connected to the lubricating oil reservoir via the lubricating oil supply line and the lubricating oil return line, the lubricating oil circuit being configured such that the lubricating oil flows through the lubricating oil circuit in one flow direction, the lubricating oil return line including an inlet point which is configured for a protective medium, which is air, being introduced into the lubricating oil return line.
A method for operating a system for supplying at least one lubrication point of a machine with a lubricating oil, the method comprising the steps of:
- providing that the system includes:
- a lubricating oil reservoir;
- at least one delivery pump;
- a heat exchanger configured for cooling the lubricating oil which is circulating;
- at least one lubrication point;
- a plurality of lines, the lubricating oil reservoir, the at least one delivery pump, the heat exchanger, and the at least one lubrication point being hydraulically connected with one another via the plurality of lines such that the lubricating oil reservoir, the at least one delivery pump, the heat exchanger, the at least one lubrication point, and the plurality of lines form a lubricating oil circuit, the plurality of lines including a lubricating oil return line, the at least one lubrication point being hydraulically connected to the lubricating oil reservoir, the lubricating oil circuit being configured such that the lubricating oil flows through the lubricating oil circuit in one flow direction, the lubricating oil return line including an inlet point which is configured for a protective medium, which is air, being introduced into the lubricating oil return line;
- and
- introducing, and regulating, the protective medium at an operating pressure vis-à-vis at least one of an atmospheric pressure and a volume flow.
