Abstract

A pump machinery sealed movable ring structure relates to a movable sealing element of mechanical sealing, and is composed of a movable ring and a movable ring base which are connected into a whole, wherein the movable ring base is wrapped on the end surface, the outer surface and the turning surface of the movable ring, and anti-rotating pins are also connected between the movable ring and the movable ring base. The pump machinery sealed movable ring structure is made of two different materials, the movable ring base adopts stainless steel metal materials to wrap and fold edges, a frangible carborundum movable ring can be formed into a metal outer shell integrity, the carborundum inside the shell can not be broken and damaged easily when the ring is collided in external environment, the service life is long, furthermore, the anti-rotating pins which are evenly distributed are also used between the movable ring and the movable ring base to connect the movable ring and the movable ring base into a whole tightly, relative siding can not be generated due to rotation and abrasion for long time to generate gaps, the integrity is good, the installation, disassembly and exchange are easy, the reliability, the anti-leakage performance and the sealing effect of the movable sealing are increased, and the pump machinery sealed movable ring structure can be matched with static rings with different structures to form mechanical sealing for being installed and used on pump shafts.

Description

Pump mechanical sealing rotating ring structure

Technical field

The utility model relates to the vitals on a kind of mechanical seal device, in particularly a kind of mechanical seal with the matching used rotary seal pump mechanical sealing of static seals rotating ring structure.

Background technique

In the rotor rotary work of pump, pump shaft for can prevent that the material in the pump housing from flowing out to outside the pump housing, all is equipped with mechanical seal device on pump shaft when the pump housing rotates, and the relevant for this reason mechanical seal device that is used for various different mediums, varying environment arises at the historic moment.

Patent No. CN200720110171.5 " a kind of mechanical seal structure of pump shaft ", its stationary ring gap is enclosed within on the pump shaft, moving ring sleeve is on the pump shaft corresponding position, the sealing surface of rotating ring and the sealing surface of stationary ring closely amplexiform and form movingly, promptly disclose a kind of can guarantee closely to be abutted against between rotating ring and stationary ring and the balance that turns round, performance good, to solving sealing, leaking the seal arrangement that plays an important role.Because of rotating ring rotates with rotor shaft, need select wear-resisting, corrosion-resistant material making for use, now generally adopt the high carbofrax material of hardness, though this material smooth abrasion-proof, wear-corrosion resistance, but if material fragility is through colliding easily cracked can not work, the running that directly influences the pump housing need be keeped in repair immediately, changed, bring inconvenience and maintenance cost to improve greatly to the user.Also slide relative can take place between time long back rotating ring, rotating seat, make its integrity poor, influence the sealing effect of rotating ring and leak-proof in addition.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of pump mechanical sealing rotating ring structure is provided, its good integrity, easy assembling, transposing, difficult broken, long service life can cooperate formation mechanical seal to install and use on pump with the stationary ring of various different structures.

The technical scheme in the invention for solving the above technical problem is: pump mechanical sealing rotating ring structure, the integral body that is connected into by rotating ring, rotating seat constitutes, described rotating seat is coated on end face, outer surface and the turnover face place of rotating ring, also is connected with stop pin between described rotating ring and rotating seat.

Compared with prior art, advantage of the present utility model is: this rotating ring structure is made up of rotating ring and rotating seat, and adopt two kinds of different materials to make, rotating seat coats and flanging with the stainless steel metal material, frangible silicon carbide rotating ring (except that with the stationary ring contacting point) make the rotating ring structure become a metal shell integral body, when being collided in the external world, it is difficult for broken the damage, increased working life, in addition at rotating ring, also both stressed joints are integral between rotating seat with uniform stop pin, can be because of long-time rotation, relative slip takes place and produces the gap in wearing and tearing, good integrity is easily installed, dismounting, transposing, maintenance.Increased the reliability of motive sealing, leakage-preventing property and sealing effect, can cooperate formation mechanical seal on pump shaft, to install and use with the stationary ring of various different structures.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Rotating ring 3 step ladder circular ring shape integral body for being made into by carbofrax material, holding greatly on 5 the edge has three uniform arc notch 4, and the end face of small end 7 is the sealing surface that cooperates with stationary ring, as 1 figure, Fig. 2, shown in Figure 3.

Rotating seat 1 is the step ladder circular ring shape that is become by the stainless steel metal material, and four openings are arranged on the small end face, breach 4 corresponding through holes 8 on uniform and the rotating ring 3 is arranged, as shown in Figure 3 on the large end face.

Earlier rotating ring 3 is pressed in the rotating seat 1, rotating seat is coating the end face and the outer surface of the big end 5 of rotating ring, the ladder turning point that one side marginal lappet of rotating seat is directly turned back and is coated on rotating ring 3 again, be on the turnover face 6 of large and

small end

5,7, and the through hole 8 of stop pin 2 on rotating seat 1 be pressed into constitute the rotating ring structure in the breach 4 on the rotating ring 3, as shown in Figure 1.

During use, the above-mentioned rotating ring structure that will have O RunddichtringO (figure draw) and a pad is installed on the pump shaft and pump shaft rotates together.And the stationary ring pine is enclosed within on the pump shaft, and stationary ring does not rotate together with pump shaft, and only the end face of the small end 7 of the nothing of an end face of stationary ring and rotating ring structure coating constitutes mechanical seal integral body and uses (figure is picture) for pump movingly.

Claims

1, a kind of pump mechanical sealing rotating ring structure, the integral body that is connected into by rotating ring, rotating seat constitutes, it is characterized in that end face, outer surface and turnover face (6) that described rotating seat (1) is coated on rotating ring (3) locate, also be connected with stop pin (2) between described rotating ring (3) and rotating seat (1).
