Problems solved by technology

The monitoring of the quantity of enclosed liquid in the system by means of level switches or float switches is only used to protect the machine and does not enable the identification or prediction of the remaining service life of the slip ring seal
[0008] However, in the case of worn slip ring seals, it is also possible that the product can escape from the grinding container into the closed liquid
Since the volume of the enclosed liquid increases here, meaningful monitoring by means of level switches or float switches is not possible

Embodiment Construction

[0058] figure 1 A device according to the invention is shown, for example an agitator ball mill 1 , which has the monitoring method according to the invention for the operating state of the sliding ring seal 2 . The agitator ball mill 1 comprises a cylindrical grinding vessel 3 which is closed on both sides by a cover plate 4 , 5 in each case. A cylindrical grinding container 3 is arranged on a housing 6 . A drive 7 and a machine controller 8 for the agitator ball mill 1 are arranged inside the housing 6 . Furthermore, an operating panel 9 is provided, via which a user can access the machine control 8 and operate the agitator ball mill 1 .

[0059] A stirrer 10 is arranged inside the grinding container 3 . The stirrer consists in particular of a stirrer shaft 11 and a stirrer element 12 arranged on the stirrer shaft. The stirring element 12 serves to activate the grinding bodies arranged in the grinding container 3 as auxiliary medium for grinding the corresponding product...

Abstract

The invention relates to a method for monitoring a physical parameter of a closed medium in a closed medium circuit of a dynamic seal of a device. In this case, at least one physical actual parameter of the enclosing medium is detected and compared with at least one defined target parameter. If a deviation between the actual parameter and the target value is detected here, this deviation is used to describe the operating state of the dynamic seal. Furthermore, the invention relates to a device having at least one rotating shaft which is sealed relative to a stationary machine part by means of a dynamic seal.

Description

technical field [0001] The invention relates to a method for monitoring a closed medium circuit of a dynamic seal and a device with a dynamic seal. Background technique [0002] In order to seal the movable parts relative to the immovable parts of the machine, dynamic seals or so-called slip ring seals are usually used. Dynamic seals or sliding ring seals are used, for example, to seal rotating shafts against stationary machine components. [0003] For example, dynamic seals or sliding ring seals are used to seal the bearing of the agitator shaft in agitator ball mills so that in particular product cannot escape from the grinding chamber of the agitator ball mill and / or cannot enter the mill of the agitator ball mill cavity. The product or ground material is ground in an agitator ball mill with the aid of grinding bodies. Agitator ball mills generally comprise a grinding vessel in which an agitator shaft is arranged. Stirring elements are arranged on the stirring shaft, ...
