Abstract
The utility model discloses a sealed isolating device, it includes: a seal spacer ring and a fixing bolt. The sealing isolation ring in the device is a key main body of innovation; the device is used for the water pump sealing bearing oil chamber, and simultaneously, water which is leaked out when mechanical sealing leaks can be isolated from the bearing oil chamber, so that the hidden danger caused by the leakage of the mechanical sealing to equipment is avoided, the blockage of an oil seal return hole of the bearing oil chamber is protected, and the low oil level caused by the tile burning accident is avoided. The temperature of the fluid medium is utilized to reduce the temperature of the mechanical seal water, so that the mechanical seal is protected, a cooling water system can be replaced, redundant equipment and pipelines of the system are reduced, and leakage points and equipment hidden dangers are reduced.
Description
Technical Field
The utility model relates to a water pump bearing grease chamber seals technical field, in particular to mechanical seal does not have a sealed isolating device in the water pump field of temperature protection.
Background
In power plant water pump equipment, a plurality of water pumps have no temperature protection monitoring system due to the conditions of rotating speed, pressure, temperature and the like, and the leakage generated during operation cannot be found in time, so that the damage is brought to the operation of the equipment. When mechanical seal leakage occurs, long-time operation is not found, mechanical seal water can be led to enter a bearing oil chamber, lubricating oil in the bearing oil chamber is extruded out of the oil chamber, bearing damage is caused, and finally the impeller and the mouth ring of the water pump with the bearing out of action are seriously abraded and other dynamic and static parts are damaged by friction.
Disclosure of Invention
An object of the utility model is to overcome prior art not enough, and provide one kind and be difficult for revealing, long service life is applicable to a mechanical seal does not have a sealed isolating device in the water pump field of temperature protection.
In order to realize the purpose of the invention, the utility model adopts the following technical scheme: a seal isolation apparatus comprising: casing, mechanical seal, bearing grease chamber, sealed isolating ring, its characterized in that: the sealing isolation ring is a ring which is made of rubber and has a T-shaped section, and the inner diameter of the sealing isolation ring is the same as the outer diameter of the shaft; the convex section of the sealing isolating ring is fixed by a bolt, the sealing isolating ring is arranged on a shaft between the bearing oil chamber and the mechanical seal, the position of the sealing isolating ring is adjusted to be close to the oil seal of the bearing oil chamber, and the sealing isolating ring is fixed on the pump shaft by the bolt. The outer ring of the sealing isolation ring is larger than the oil seal of the oil chamber of the bearing.
When the pump operates, the sealing isolation ring rotates along with the pump shaft, the oil chamber side plays a role of a secondary oil seal of the oil chamber, and the mechanical sealing side plays a role of preventing leakage pressure water from entering the oil chamber to cause damage to a bearing.
The utility model discloses effectually prevent that mechanical seal from revealing the harm that does not move the water-feeding pump for a long time under the monitoring condition and bring, improved the reliable operation of equipment greatly.

Detailed Description
The invention will be further explained with reference to the following description of the drawings.
A seal isolation apparatus comprising: casing, mechanical seal, bearing grease chamber, sealed isolating ring, its characterized in that: the sealing isolation ring is a ring which is made of rubber and has a T-shaped section, and the inner diameter of the sealing isolation ring is the same as the outer diameter of the shaft; the convex section of the sealing isolating ring is fixed by a bolt, the sealing isolating ring is arranged on a shaft between the bearing oil chamber and the mechanical seal, the position of the sealing isolating ring is adjusted to be close to the oil seal of the bearing oil chamber, and the sealing isolating ring is fixed on the pump shaft by the bolt. The outer ring of the sealing isolation ring is larger than the oil seal of the oil chamber of the bearing.
When the pump operates, the sealing isolation ring rotates along with the pump shaft, the oil chamber side plays a role of a secondary oil seal of the oil chamber, and the mechanical sealing side plays a role of preventing leakage pressure water from entering the oil chamber to cause damage to a bearing.
