Abstract
The utility model discloses a frameless contact-type oil seal. The frameless contact-type oil seal comprises a fluororubber sealing member body and a compression spring, wherein the frameless contact-type oil seal is elastically connected with a side cover of a bearing seat; the fluororubber sealing member body is in interference fit with a main shaft, and the one thirds position of the fluororubber sealing member body is provided with a lip-shaped groove and an oil guide port on the basis. The utility model has the advantages of ensuring that lubricating oil can not pollute the environment by flowing out and the lubricating oil can uniformly lubricate an integer by bearing certain oil pressure and also preventing the temperature of the lubricating oil from being increased because heat is generated by rubbing an oil seal body and the main shaft.
Description
Technical field
The utility model relates to a kind of oil sealing, is specifically related to a kind of contact-type oil sealing of centrifugal blower.
Background technique
Under the overall background that environment protection emission requires to tend towards superiority, recirculating fluidized bed power station unit is because burning low grade coal, gangue, coal washing mud etc., and can realize relative low-temperature burning; Meet national industry development guiding, 600MW is supercritical circulating fluidized bed to belong to National Development and Reform Committee's electric power development directory items, is contactless oil sealing and the oil sealing great majority of centrifugal blower are in the past taked; Like labyrinth oil sealing etc., the characteristics of labyrinth oil sealing are simple in structure, and are easy for installation; But to requirement on machining accuracy than higher; Also occurred in the past not causing oil leakage phenomenon because of machining accuracy reaches, the fan bearing of the supercritical circulating fluidized bed overfire air fan of 600MW is taked pressure lubrication, and Xi oil standing-meeting applies very big oil pressure to bearing housing; Traditional labyrinth oil seal such as machining accuracy do not reach; Gently then lubricant oil spills the pollution site environment, and situation seriously may burn out a bearing, and brings loss.
The model utility content
The model utility purpose: the purpose of the utility model is in order to remedy the deficiency of existing technology, to provide a kind of lubricant oil that prevents to flow out and can bear the exoskeletal contact-type oil sealing of certain oil pressure.
Technological scheme: a kind of exoskeletal contact-type oil sealing; Comprise fluorine rubber seal element body and pressure spring; Described this body elasticity of fluorine rubber seal element is connected in the bearing support side cover; Described fluorine rubber seal element body and main shaft adopt interference fit, and 1/3rd places of fluorine rubber seal element body are provided with lip groove and oil diverting port according to this.
Seal body has adopted fluorine rubber (FKM), and fluorine rubber still has good physical property under high temperature (the highest 250 degrees centigrade) condition.Also have extraordinary oil resistant, fuel oil, solvent and chemical product performance.
Described elasticity is connected to the spring that is provided with through fluorine rubber seal element body outer ring and is connected with the bearing support side cover.Make oil sealing and bearing support side cover that certain expansionary force is arranged like this, also convenient simultaneously mounting or dismounting.
Beneficial effect: after the utility model has adopted such structure, can prevent the lubricant oil outflow and can bear certain oil pressure, make lubricant oil can evenly lubricate to whole.Avoid generating heat, cause oily temperature rise because of oil seal body and main shaft friction.
