Abstract
The utility model discloses a three-step sealing device for a pump, which comprises a sealing seat, a static ring and a moving ring, wherein the sealing seat is arranged on a shaft of the pump; the front cavity of the sealing seat is filled with filler and is sealed by a filler gland and locked by a screw; the rear end of the sealing seat is embedded with the static ring and the moving ring which is matched with and corresponds to the static ring; and the sealing ring is provided with a through hole used for introducing inert gas. The sealing device guarantees the pump not to leak when in medium delivery, avoids polluting the environment, improves the economic benefit, prolongs the service life of the pump and reduces the cost.
Description
Technical field: the utility model relates to a kind of three-stage sealing device of pump.
Background technique: pump is widely used in industries such as chemical industry, oil, pharmacy, agricultural chemicals, dyestuff, paint, smelting, plating, food.The arbitrary medium of any concentration of long-term delivery under the condition of-20 ℃ of-100 ℃ of temperature is except that carrying hard crystalline solid medium fast.So general pump exists race, emits, leaks, drips the phenomenon of befouling environment, has reduced manufacturing efficiency, has improved repair cost, has shortened the working life of pump.
Summary of the invention: the purpose of this utility model is exactly the three-stage sealing device that a kind of pump will be provided, and it can overcome the leakage problem that general pump all exists well.The purpose of this utility model is achieved in that the three-stage sealing device of pump, is made up of sealing seat, stationary ring, rotating ring, and it is characterized in that: pump shaft is provided with sealing seat, is provided with filler in the ante-chamber of sealing seat, and by Gland sealing, screw lock; Described sealing seat rear end is embedded with stationary ring, and is provided with and the stationary ring corresponding rotating ring that matches; Described sealing seat is provided with through hole, is used for logical inert gas.The seal arrangement that the utility model is provided with can seepage when having guaranteed the pump fed sheet of a media, has stopped environmental pollution, has improved economic benefit, has prolonged the working life of pump, has reduced cost.
Description of drawings:
Fig. 1 is the utility model structural representation;
1. Gland, 2. filler, 3. sealing seat, 4. stationary ring, 5. rotating ring, 6. through hole.
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing;
The three-stage sealing device of pump is made up of sealing seat 3, stationary ring 4, rotating ring 5, and it is characterized in that: pump shaft is provided with sealing seat 3, is provided with filler 2 in the ante-chamber of sealing seat 3, and by Gland 1 sealing, screw lock; Described sealing seat 3 rear ends are embedded with stationary ring 4, and are provided with and the stationary ring 4 corresponding rotating ring 5 that matches; Described sealing seat 3 is provided with through hole 6, is used for logical inert gas.During concrete enforcement, first order seal arrangement is made up of sealing seat and filler, on pump shaft, will load onto by the sealing seat that figure processes, on sealing seat ante-chamber pump shaft, add filler then, Gland sealing, screw lock, the filler place is provided with oilhole by sealing seat can feed lubricant oil on time, cooling or lubricated.Second level seal arrangement is made up of stationary ring, rotating ring, is packed with stationary ring in the sealing seat rear end, and is screwed, and puts the corresponding rotating ring that matches with it then on axle.Third level seal arrangement is that sealing seat is provided with through hole, is used for logical nitrogen, further seals rotating ring and stationary ring sealing part, prevents the medium seepage.
