Abstract
The utility model belongs to a sealing device, particularly a sealing ring for automatic circulation cooling machinery. The utility model has the main technical proposal that a drive shaft is sheathed with a sealing sleeve, and a graphite stator ring is arranged at the joint part of the sealing sleeve and the drive shaft, wherein, the drive shaft in the sealing sleeve is provided with pump vanes, and the wall of the sealing sleeve is provided with a water inlet and a water outlet; the joint part of the graphite stator ring and the sealing sleeve is provided with a fluorine rubber ring; the drive shaft is provided with a hard moving ring of which the axial end face is closely contacted with the axial end face of the graphite stator ring; the joint part of the graphite stator ring and the drive shaft is provided with a fluorine rubber ring. Because the inner part of the sealing member is provided with a cooling device, the problem of ineffective sealing rings caused by high temperature can be avoided, and the sealing performance is improved.
Description
Technical field
The utility model belongs to seal arrangement, refers in particular to a kind of automatic cycle cooling mechanical seal ring.
Background technique
In the prior art, generally the mechanical sealing element of Shi Yonging is a kind of rotating component that is used in the positive/negative pressure container, seals, because this Sealing is in work under the high speed rotating state, produce high temperature because of friction between graphite stationary ring and hard rotating ring, make the Sealing that places in the rotating ring---the distortion of fluorine cushion rubber, cause leaking in the pressurized container, shortened the working life of Sealing.
Summary of the invention
The purpose of this utility model is to design a kind of automatic cycle cooling mechanical seal ring, owing in this Sealing, be provided with cooling unit, thereby the problem of having avoided Yin Gaowen to cause seal ring to lose efficacy, improved sealability.
Its main technical schemes is to overlap stuffing box gland on transmission shaft, in the connecting part of stuffing box gland and transmission shaft graphite stationary ring is set, and the pump leaf is set on the transmission shaft in stuffing box gland, and water intake and water outlet are set on the wall of stuffing box gland.
In the connecting part of graphite stationary ring and stuffing box gland the fluorine cushion rubber is set; The hard rotating ring is set on transmission shaft, and the axial end of this hard rotating ring closely contacts with the axial end of graphite stationary ring; In the connecting part of graphite stationary ring and transmission shaft the fluorine cushion rubber is set.
Sleeve spring on the transmission shaft in stuffing box gland has the mechanical seal outer ring that is installed on the transmission shaft outside spring, the pump leaf is installed on the mechanical seal outer ring.
Stuffing box gland utilizes bolt to be installed on the motor cabinet, and transmission shaft is connected with motor shaft, at the opposite side of motor cabinet motor is installed; On the transmission shaft that is positioned between spring and hard rotating ring, resting type spring support is set; Connecting part at transmission shaft and motor cabinet is provided with outside framework oil seal.
The utility model has the advantages that because the pump leaf has been installed outside transmission shaft, when transmission shaft rotates, driving the pump leaf rotates, the rotation of pump leaf can make the cooling water that is positioned between stuffing box gland and mechanical seal outer ring wash away graphite stationary ring and hard rotating ring, force graphite stationary ring and hard rotating ring to obtain forcing cooling, improve cooling effect, the temperature of graphite stationary ring and hard rotating ring is remained in the safety temperature, fundamentally stop the distortion and the charing phenomenon of fluorine cushion rubber, guarantee that machinery can turn round for a long time, enhance productivity.
