Description
Technical field
This utility model relates to the technical field of water-tight equipment, a kind of durable external mechanical seal.
Background technology
End face seal is named again in mechanical seal, refers to be perpendicular to the end face of the rotation axis lower device preventing fluid from leaking keeping laminating relative slip and constitute with fluid pressure with the effect of compensation mechanism elastic force (or magnetic force) and auxiliary seal from least one pair of.Mechanical seal is the gland seal device of a kind of rotating machinery, the equipment such as such as centrifugal pump, centrifuge, reactor and compressor, owing to power transmission shaft is applied in inside and outside equipment, a circumferential clearance is there is between axle and equipment, medium in equipment is leaked out by this gap, if pressure subatmospheric in equipment, then air is to equipment internal leakage, and mechanical seal is these equipment topmost sealing modes.
Nowadays, along with improving constantly of science and technology, the technology of mechanical seal is required more and more higher by relevant industries, but existing mechanical seal uses unbalanced type internally mounted mechanical seal substantially, in there is granule and deep-etching acid medium, after generally using very short time, particulate matter between its rotating ring and sealing surface of stationary ring, will be entered, and mutually abrasion thus cause leakage failure；And the tar class in cleaning mixture easily bonds and makes spring bullet the most out after spring, causes amount of spring compression to reduce, thus causes seal failure to leak；Built-in additionally, due to mechanical seal, after leakage failure, it is necessary to termination of pumping dismounting is disintegrated, check and adjust the decrement of spring or change mechanical seal, could again recover normal after precision is installed, therefore repair rate and the cost of overhaul are the highest.
Utility model content
Utility model purpose: in order to overcome above deficiency, the purpose of this utility model is to provide a kind of durable external mechanical seal, and this mechanical seal can run by No leakage for a long time, service life is long, and the handling of its all parts are simple and convenient, and termination of pumping repair rate is low, and repair and maintenance cost is little.
Technical scheme: in order to realize object above, a kind of durable external mechanical seal described in the utility model, include stationary ring, corrugated tube rotating ring, spring base, spring, throw-out collar, point partly clamp pipe, retainer ring and stop pin；Described corrugated tube rotating ring is connected by screw and pump block are fixing, and described corrugated tube rotating ring connects with stationary ring, spring base respectively, is inlaid with spring inside described spring base, and described spring top is connected with throw-out collar；Described former and later two points half clamping ring is connected to each other by hexagon socket cap head screw becomes an entirety, and described point of half clamping ring is connected with corrugated tube rotating ring, throw-out collar and retainer ring respectively；Described stop pin sequentially passes through point half clamping ring, throw-out collar and spring base up and down, and described retainer ring is connected by interior hexagon concave-end locking screw and axle sleeve are fixing.This utility model is by being directly arranged in outside seal box by corrugated tube rotating ring and spring base, thus avoid the wear out failure leakage caused between corrugated tube rotating ring and stationary ring sealing surface because entering particulate matter, greatly facilitate the maintaining after staff observes leakage situation and leakage at any time simultaneously；And staff is by unscrewing the screw on point half clamping ring, retainer ring and corrugated tube rotating ring, the handling of each parts are very convenient to, the decrement of spring can also be adjusted rapidly as required, is therefore greatly improved the efficiency that maintenance adjusts, reduces repair and maintenance cost；When the absorption of other high viscosity particulate matter is on spring and corrugated tube rotating ring and stationary ring sealing surface, though leakage can also not termination of pumping online, by low pressure water vapor or hot water, adsorbate is rinsed so that its to recover rapidly No leakage properly functioning.
Spring base one end described in this utility model is provided with adjusting nut.Adjusting nut in this utility model can regulate the decrement of spring as required, thus is further ensured that its long-play No leakage.
Leave the space of 2-3mm described in this utility model between spring base and throw-out collar, thus be the maintenance adjustment slot milling in later stage.
Preferably, stationary ring described in this utility model and corrugated tube rotating ring are prepared by carbofrax material intefused tetratiuorine.Stationary ring in this programme and corrugated tube rotating ring good corrosion resistance, both sealings are all further enhanced.
A diameter of 3mm of stop pin described in this utility model.
Beneficial effect: compared with prior art, this utility model has the advantage that
1, a kind of durable external mechanical seal described in this utility model, it avoids the wear out failure leakage caused because entering particulate matter between corrugated tube rotating ring and stationary ring sealing surface well, greatly facilitates the maintaining after staff observes leakage situation and leakage at any time simultaneously；And the handling of its each parts are very convenient to, the decrement of spring can also be adjusted rapidly as required, is therefore greatly improved the efficiency that maintenance adjusts, reduces repair and maintenance cost.
2, a kind of durable external mechanical seal described in this utility model, when the absorption of high viscosity particulate matter is on spring and corrugated tube rotating ring and stationary ring sealing surface, even if leakage can also not termination of pumping online, by low pressure water vapor or hot water, adsorbate is rinsed, so that its rapid recovery No leakage is properly functioning.
3, a kind of durable external mechanical seal described in this utility model, its adjusting nut can regulate the decrement of spring as required, and stationary ring and corrugated tube rotating ring good corrosion resistance, both sealings are all further enhanced, therefore further ensuring its long-play No leakage, the life-span extends 3-5 times compared with originally；The space additionally left between its spring base and throw-out collar is that later maintenance adjustment also reserves suitable space.
