Abstract
The utility model discloses a novel mechanical sealing device. The novel mechanical sealing device comprises a mechanical sealing seat arranged on a shaft sleeve, wherein the mechanical sealing seat is in matching connection with a corrugated pipe seat by a graphite ring; one end of a corrugated pipe is arranged on the corrugated pipe seat, and the other end of the corrugated pipe is connected with a moving ring which is contacted with the end surface of a static ring; a static ring seat and the static ring are embedded and sheathed into a whole body by treatment; the static ring seat is subjected to anticorrosion treatment. The novel mechanical sealing device disclosed by the utility model has the advantages that original small end-surface clearances caused by matching connection of the graphite ring are eliminated, the leaking points of mechanical sealing in the shaft sealing process are reduced, and the overall efficiency of a pump in operation is improved.
Description
Technical field
The utility model relates to mechanical seal field, is specially mechanical sealing device.
Background technique
Mechanical seal, as a kind of gland seal device of rotating machinery, is widely used in the equipment such as centrifugal pump, centrifuge.In the prior art, mechanical face seals of centrifugal pumps is conventionally being closely cooperated and is being arranged on axle sleeve by graphite annulus and stationary seat, realizes the function of shaft seal; But at one section of all after date of running, often there is micro-face leakage between stationary seat and machine envelope stationary ring in pump, the time has been grown and can cause the output of pump unstable.
Model utility content
The technical problem that the utility model solves is to provide a kind of mechanical sealing device, to solve the problem in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
Mechanical sealing device, comprise the machine envelope seat being arranged on axle sleeve, machine envelope seat is connected by graphite annulus with corrugated header, bellows one end is arranged on corrugated header, the other end is connected with rotating ring, rotating ring and stationary ring end contact, stationary seat is an integral body with stationary ring by processing nested, described stationary seat is through anti-corrosion treatment.Eliminate the small end clearance that former cause graphite annulus is connected and causes, reduced machine and be enclosed in the leakage point in shaft seal process, improved the whole efficiency of pump when operation.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, mechanical sealing device, comprise the machine envelope seat 6 being arranged on axle sleeve 7, machine envelope seat 6 is connected by graphite annulus 8 with corrugated header 5, bellows 4 one end are arranged on corrugated header 5, and the other end is connected with rotating ring 3, rotating ring 3 and stationary ring 2 end contacts, stationary seat 1 is an integral body with stationary ring 4 by processing nested, and described stationary seat is through anti-corrosion treatment.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
