Abstract
A mechanical seal, comprising: the movable ring is provided with a raised head at the position opposite to the gland, the gland is sealed with the shell through the gland sealing ring, a corresponding groove is formed at the position, opposite to the raised head of the movable ring, of the gland serving as the static ring, a corresponding groove is formed in the position, opposite to the raised head of the movable ring, of the gland, graphite is arranged in the groove, and the raised head of the movable ring is pressed on the graphite in the groove of the gland to realize sealing.
Description
Technical Field
The mechanical seal belongs to dynamic seal and is widely applied to various pumps, kettles, turbine compressors and other equipment.
Background
Modern seals are mainly: the most widely used of the traditional packing seal, mechanical seal, mud seal, cartridge seal, etc. is mechanical seal, the friction coefficient in the mechanical seal is the most important point, and the electrochemical graphite has good self-lubricating property and low friction coefficient, but is inconvenient to use in the mechanical seal due to its soft texture.
Disclosure of Invention
In view of the above, the present invention provides a new mechanical seal using graphite as a static seal ring, in order to solve the problem that graphite is soft and inconvenient to use in mechanical seals.
The technical scheme of the invention is as follows: the mechanical seal transmission shaft is fixed with a spring seat and a movable ring capable of moving axially, a spring is arranged between the spring seat and the movable ring, a movable ring sealing ring is arranged between the movable ring and the transmission shaft for sealing, a raised head is arranged at the position of the movable ring opposite to the gland, a gland sealing ring is arranged between the gland and the shell for sealing, a corresponding groove is arranged at the position of the gland serving as a static ring and the raised head of the movable ring, the groove is internally provided with electrochemical graphite, and the raised head of the movable ring is pressed on the electrochemical graphite in the groove of the gland under the action of the spring so as to realize sealing.
The invention realizes the use of the electrochemical graphite with low friction coefficient and soft texture in mechanical sealing and improves the mechanical sealing efficiency.
Drawings
FIG. 1 is a sectional view of the structure of the present invention.
Detailed Description
In the figure: 1. the transmission shaft, 2, the spring holder, 3, a spring, 4, the rotating ring, 5, the rotating ring sealing washer, 6, gland (quiet ring), 7, the electrographite, 8, gland (quiet ring) sealing washer, 9, a housing, but mechanical seal transmission shaft 1 is last to be fixed with spring holder 2 and axially movable's rotating ring 4, there is spring 3 between spring holder 2 and the rotating ring 4, it is sealed to have rotating ring sealing washer 5 between rotating ring 4 and the transmission shaft 1, rotating ring 4 has the plush copper in the position relative to gland (quiet ring) 6, it is sealed to have gland (quiet ring) sealing washer 8 between gland (quiet ring) 6 and the housing 9, gland 6 and rotating ring plush copper position as quiet ring have corresponding recess, there is electrographite 7 in the recess, the rotating ring plush copper pushes down on gland (quiet ring) recess electrographite 7 under the effect of spring 3, in order to realize sealed.
