Problems solved by technology

[0009] In almost all prior art cases, the condition of the seal is monitored more or less by an external sensor, which is completely understandable since mechanical seals are not easily accessible and there is no simple solution for monitoring the condition of the seal on the market. device

Embodiment Construction

[0038]figure 1 A mechanical seal arrangement according to a preferred embodiment of the present invention is depicted, comprising a schematically and exemplarily shown single acting mechanical seal 10 and a signal processing arrangement 30 . The invention is of course also applicable to double-acting mechanical seals. A mechanical seal 10 is used to seal, for example, the shaft 8 of a draft machine (shown in dashed lines) such that the interior of the draft machine (at the left hand side of the seal 10 ) is kept from the atmosphere (at the right hand side of the seal 10 ) separate. The mechanical seal 10 is located in a seal chamber provided within a particular seal housing or within the housing cover of the flow generator.

[0039] The mechanical seal 10 includes a rotating portion 12 and a non-rotating portion 20 . The rotating part 12 includes a retainer ring 14 , a rotating slip ring bracket 16 and a rotating slip ring 18 . A rotary slip ring 18 is attached to an axial ...

Abstract

The present invention relates to a mechanical sealing arrangement, the mechanical sealing arrangement (10) having a rotary part (12), a non-rotary part (20) and a signal processing arrangement (30), the rotary part (12) comprising at least a rotary slide ring (18) and a rotary slide ring carrier (16), the non-rotary part (20) comprising at least a non-rotary slide ring (24) and a non-rotary slide ring carrier (22), and the signal processing arrangement (30) comprising at least one sensor (38, 48) for monitoring the operation of the mechanical sealing arrangement, wherein a sensor ring (32) is provided on the non-rotary slide ring carrier (22), the sensor ring (32) being provided with the at least one sensor (38, 48) and means (34) for transmitting measurement data from the at least one sensor (38,48) to further processing.

Description

technical field [0001] The invention relates to a mechanical seal arrangement according to the preamble of claim 1 and a sensor ring according to the preamble of claim 11 . Background technique [0002] Mechanical seals are gaining acceptance in a variety of shaft sealing applications. Mechanical seals find use in a variety of pumps, mixers and agitators. Mechanical seals have a relatively simple construction, are resistant to high temperatures, and are relatively easy to maintain and repair. However, like all seals, its lifespan is difficult to predict. It is also completely impossible to carry out any visual monitoring of the condition of the seal. Accordingly, the prior art includes numerous documents that discuss monitoring the condition of mechanical seals. [0003] US-A-6,065,345 discusses a method of monitoring the condition of a mechanical seal in a device provided with a rotating part, in particular in a pump with a rotating shaft for conveying fluid. Acoustic ...
