Embodiment 1

[0045] A water-cooled single-end mechanical seal structure, including a rotating shaft 1, a rotating wheel 10, a spring 9, a gasket 11, a first sealing ring 12, a moving ring 2 and a static ring 3 arranged on the rotating shaft 1 in sequence, wherein the rotating wheel 10 is sleeved and fixed on one end of the rotating shaft 1, and the moving ring 2 can also be fixed on the rotating shaft 1 so that it can rotate synchronously with the rotating shaft 1. At the same time, the moving ring 2 has a concave arc for placing the gasket 11, and the gasket 11 and the A first sealing ring 12 is arranged between the moving rings 2, and the spring 9 is sleeved on the rotating shaft 1 between the runner 10 and the gasket 11. At this time, the spring 9 is in a compressed state, and the gasket 11 can be pressed. Make the first sealing ring 12 play a good sealing effect.

[0046] This application adopts a single-end mechanical seal structure. Compared with the double-end mechanical seal struct...

Embodiment 2

[0065] The single-end mechanical seal structure in the second embodiment has been disclosed in the first embodiment, so it will not be repeated here.

[0066] A water-cooled working method of a single-end mechanical seal structure,

[0067] It includes a rotating shaft 1, a moving ring 2 and a static ring 3 sleeved on the rotating shaft 1; a water inlet pipeline 31 and a water outlet pipeline 32 are arranged between the moving ring 2 and the static ring 3, and the water inlet pipe The channel 31 and the water outlet pipe 32 communicate with each other, wherein coolant is injected from the water inlet pipe 31 and discharged from the water outlet pipe 32 to cool the moving ring 2 and the static ring 3 .

[0068] The water-cooling working method of the single-end mechanical seal structure of the present invention has excellent water-cooling effect and reduces the risk of leakage caused by the temperature rise of the mechanical seal.

[0069] In this embodiment, an impeller 4 is ...

Abstract

The invention relates to a water-cooling single-end-face mechanical sealing structure and a working method thereof. The water-cooling single-end-face mechanical sealing structure comprises a rotatingshaft, a rotating wheel, a spring, a gasket, a first sealing ring, a movable ring and a static ring, wherein the rotating wheel, the spring, the gasket, the first sealing ring, the movable ring and the static ring are arranged on the rotating shaft in sequence, a water inlet pipeline and a water outlet pipeline are arranged between the movable ring and the static ring, the water inlet pipeline andthe water outlet pipeline communicate with each other, and coolant is suitable for being injected from the water inlet pipeline and discharged from the water outlet pipeline so as to cool the movablering and the static ring. According to the water-cooling single-end-face mechanical sealing structure, the water inlet pipeline and the water outlet pipeline are arranged, so that the circulation ofthe coolant is realized, and the heat generated by the friction between the end surfaces of the movable ring and the static ring is taken away.

Description

technical field [0001] The invention relates to the field of water pumps, in particular to a water-cooled single-end mechanical seal structure and a working method thereof. Background technique [0002] The mechanical seal of the existing water pump generally adopts the form of a single-end mechanical seal without water cooling, but this type of seal will cause the temperature of the contact end surface of the moving ring and the static ring to be too high when the water pump has no liquid entering the idling state, thereby burning the rubber. Seals and accelerate the aging of rubber seals. Leakage of the liquid delivered by the pump. Contents of the invention [0003] The purpose of the present invention is to provide a mechanical seal structure with water cooling single end face. [0004] The invention provides a water-cooled single-end mechanical seal structure, including a rotating shaft, a rotating wheel, a spring, a gasket, a first sealing ring, a moving ring and a...
