Embodiment Construction

[0022] The following will refer to Figure 1-3 Now, the mechanical seal device 1 including the conveying mechanism 5 of the present invention will be described.

[0023] Such as figure 1 As shown, the mechanical seal device 1 of this embodiment is configured in the form of a double-acting mechanical seal device, which has a first mechanical seal 11 and a second mechanical seal 21 . The mechanical seal 1 now seals the product zone 30 from the atmospheric zone 31 . The first mechanical seal 11 includes a rotary seal ring 2 and a stationary seal ring 3 , defining a seal gap 4 between them. Likewise, the second mechanical seal 21 is configured with a rotating sealing ring 22 and a stationary sealing ring 23 defining a sealing gap 24 therebetween.

[0024] Here, in the axial direction X-X, a conveying mechanism 5 is arranged, which is mounted on a bushing 15 fixed to the shaft 14 . At this time, the engaging part 16 is also fixed on the shaft sleeve 15 and connected with the ro...

Abstract

The invention relates to a mechanical sealing device, comprising: a rotating sealing ring (2) and a stationary sealing ring (3), defining a sealing gap (4) between them; a conveying mechanism (5) for conveying fluid, wherein the The conveying mechanism (5) has a sleeve-shaped body (6) comprising a first through hole (7) and a second through hole (8), the conveying mechanism (5) rotates together with the rotary sealing ring (2), wherein the The first through holes (7) respectively have a first inlet area (70) on the outer peripheral surface of the sleeve-shaped body (6) and a first outlet area (71) on the inner peripheral surface of the sleeve-shaped body (6). , and the second through hole (8) has a second inlet area (80) on the inner peripheral surface of the sleeve-shaped main body (6) and a second outlet area on the outer peripheral surface of the sleeve-shaped main body (6) (81).

Description

technical field [0001] The invention relates to a mechanical seal with a rotating feed mechanism for improved cooling of a mechanical seal. Background technique [0002] Different embodiments of mechanical seals are disclosed in the prior art. A cascade of problems in such mechanical seals generally resides in the relatively high temperatures that may occur in operational use. To avoid damage to the mechanical seal, it is therefore necessary to dissipate heat. It is known to dissipate this heat, for example, with a separate supply medium. To circulate such a supply medium, externally mounted pumps are usually used. In addition, so-called pump rings can also be used, for example, but they generally only provide a low delivery performance and thus only ensure a low heat dissipation. Furthermore, it is known from DE 10 2011 118 294 A1 to use Tesla pumps for circulating the supply medium. The Tesla pump has proven itself in principle, but it is desired to have alternatives,...
