Embodiment Construction
[0061] figure 1 The apparatus 1 or its associated parts are schematically depicted with a shaft 14 rotatably supported in the body 22 and a mechanical seal 11 arranged to the rotatably supported shaft 14 . The shaft and device are run by a motor 17 coupled to shaft 14 to seal the inside of the device from the outside of the device. exist figure 1 In the preferred embodiment, the seal 18 includes a rotating portion 24 and a non-rotating portion 26 . figure 1 The rotating part 24 includes a retaining ring, a rotating slip ring carrier and a rotating slip ring 28 . A rotary slip ring 18 is attached to the axial end of the rotary slip ring carrier. The non-rotating component 26 includes a non-rotating slip ring carrier, a non-rotating slip ring 30 and a pressure ring. A non-rotating slip ring 30 is attached to the end of the non-rotating slip ring carrier. When used in a fluid machine, slip rings 28 and 30 are in mechanical contact with each other. Apart from figure 1 In ad...

The present invention relates to a method of operating a sealing monitoring system (10) in a sealing (11) of a rotatable shaft (14). According to the present invention, the sealing (11) provided with a flushing liquid system (32) between a rotatable shaft (14) and a stationary housing (22), and a first liquid detector (40) configured to detect the presence of flushing liquid in the flushing liquid system (32) are included, and the method comprises detecting a first flushing liquid presence status in the flushing liquid system by means of a first liquid detector (40), and a) in case the first flushing liquid presence status is affirmative, transmitting the first flushing liquid presence status for further processing by using a wireless data communication system (36) with a first data transmission interval between the transmissions, and b) in case the first flushing liquid presence status is negative, transmitting the first flushing liquid presence status for the further processing by using the wireless data communication system (36) with a second data transmission interval being shorter than the first transmission interval between the transmissions.
Description
technical field [0001] The invention relates to a method of operating a seal monitoring system in a seal of a rotatable shaft, the invention also relates to a seal monitoring system for a seal connected to a rotatable shaft, comprising a flushing fluid system, the seal being arranged Between the rotatable shaft and the seal housing. Background technique [0002] The present invention relates to the monitoring of mechanical seals in pumps or similar fluid machines having a mechanical seal on a rotatable shaft thereof. Mechanical seals are gaining increasing acceptance in a variety of shaft sealing applications. Mechanical seals are used in a wide variety of pumps, mixers and agitators. Mechanical seals have a relatively simple structure, they are resistant to high temperatures, and their maintenance and maintenance are relatively easy. However, like all kinds of seals, their lifespan is unpredictable. It is also completely impossible to perform any visual monitoring of th...
