Problems solved by technology

[0002] It is a relatively common phenomenon that oil mist appears in bearings during the operation of hydropower units, but the problem of oil mist will bring huge safety hazards to the safe and stable operation of the unit
At present, there are two main types of oil mist sealing devices in hydropower units. One is non-contact sealing, and its structure is mainly a labyrinth seal. A single labyrinth seal only increases the flow resistance, and the effect of preventing oil mist leakage is not significant; the other One type is contact seal, mainly felt seal, or polymer material is used as friction pair for sealing, but there are also disadvantages such as poor lubricity, serious friction and wear, etc. For this reason, a high-efficiency oil mist sealing device and sealing method are proposed

Embodiment Construction

[0025] Below we combine the Figure 1-4 A high-efficiency oil mist sealing device and its use method according to the present invention will be further described.

[0026] See attached Figure 1-2 As shown, a high-efficiency oil mist sealing device in this embodiment includes: a bracket 1, a labyrinth seal ring 2 installed on the bracket 1, a gasket 4 installed on the labyrinth seal ring 2, and a seal gasket installed on the gasket 4. Brush seat 5, sealing plate 8 installed on brush seat 5, pressure plate 6 installed on sealing plate 8, sealing brush 7 is installed on brush seat 5, sealing brush 7 includes base 703 and bristle assembly 704 installed on the base , through the non-contact seal of the labyrinth seal ring 2 and the contact seal of the seal brush 7, the oil mist generated during the operation of the equipment can be sealed twice to improve the sealing performance and achieve the purpose of preventing oil mist leakage.

[0027] See attached Figure 2-3 As shown, ...

Abstract

The invention discloses an efficient oil mist sealing device. The efficient oil mist sealing device comprises a bracket, a labyrinth sealing ring mounted on the bracket, a sealing gasket mounted on the labyrinth sealing ring, a brush holder mounted on the sealing gasket, a sealing plate mounted on the brush holder, and a pressing plate mounted on the sealing plate, the efficient oil mist sealing device is characterized in that a sealing brush is mounted on the brush holder, and the sealing brush comprises a base and a bristle assembly mounted on the base. The efficient oil mist sealing deviceis simple in structure, oil mist leakage can be effectively prevented through non-contact sealing of the labyrinth sealing ring and contact sealing of the sealing brush, the nylon-material made sealing brush which is good in elasticity and resistant to abrasion is adopted, meanwhile, the sealing brush is coated with a adhesive sticker and a silicone oil, the lubricity of the sealing brush is improved, the sealing performance of the sealing device is improved, and due to the detachable structural design of a bolt, the device is convenient to mount and dismount.
