Problems solved by technology

However, there is a risk of increased wear due to insufficient lubrication and this can lead to accelerated wear and a shortened service life of the machines involved
[0006] The construction and maintenance of such systems usually requires design and production with suitably small tolerances, as well as costly adjustments during assembly and costly maintenance during future operation

Embodiment Construction

[0020] The following will be based on Figure 1 to Figure 3 Before proceeding to a detailed explanation of embodiments of the invention, it is first pointed out that, although the following description focuses on the embodiments in relation to these respective pumps, embodiments of the invention are in principle not limited to lubricant systems. The media mentioned in this description are usually lubricants, such as engine oil or grease, but embodiments of the invention are in principle not limited to these media. For example, a pump according to one embodiment of the invention is also suitable for conveying another medium.

[0021] For example, a substantially incompressible liquid or another viscous substance may be used as the medium, including, but not limited to, the aforementioned greases and other emulsions. It is likewise possible to use solid substances as media, for example carbon-based fine-grained bulk materials. However, other media can also be conveyed by the p...

Abstract

The pump (100) for conveying a medium comprises a pump chamber (130) having an inlet opening (170) and an outlet opening (190). A movable component (150) is provided, which is at least arranged partially in the pump chamber in a movable manner and is adapted to receive an amount of the medium in the pump chamber (130) from the inlet opening to the outlet opening (190). A ventilation device (210) is formed and has a ventilation opening (220) which is located in the pump chamber and is different from the inlet opening (170) and the outlet opening (190), and the ventilation device (210) is used to at least temporarily reduce or substantially prevent the formation of a negative pressure in the pump chamber.

Description

technical field [0001] The invention relates to a pump for conveying a medium, a lubricant system and a method for conveying a medium, for example an essentially incompressible medium such as a liquid, a lubricant, a grease, an oil or an emulsion. Background technique [0002] Conveying medium is a main task or auxiliary task in many machines, for example, it needs to be used to maintain the function of related machines, for example, coolant or lubricant must be frequently delivered to a certain part or multiple parts in the machine. In the case of lubricants, the relevant locations are usually bearings, such as rolling bearings or sliding bearings, or other areas where the relative movement of individual machine components is to be reduced and / or cooled. [0003] It is often necessary to fine-tune the individual components of such a medium delivery system to coordinate them with one another in order to ensure that the relevant medium is supplied as fully as possible under a...
