Abstract
An integral mechanical seal for submersible motor-pump, which essentially consists of a sealed box, a static ring, an elastic retainer ring for hole, a rotational ring, an O-shaped gasket, a spring, a rotational support, a shaft sleeve, etc; the rotational ring is integrated by a metal rotational ring seat and a non-metal rotational ring body which are mutually inlaid; the upper end face of the metal rotational ring seat is provided with a ring-shaped groove; the non-metal rotational ring body is inlaid in the ring-shaped groove and fixed and connected to the metal rotational ring seat; the non-metal rotational ring body is made of silicon carbide or ceramics; the rotational ring body is adhered and combined in the ring-shaped groove with glue at least resistant to 200 Celcius System. The utility model has advantages of simple and reasonable structure, convenience and reliability in use, longer service life, higher safety performance, great reduction of the back repair rate of water pumps from the users and the maintenance cost, etc.
Description
Technical field
The utility model relates to a kind of integrated type mechanical seal that is exclusively used in Submerged Motor Pumps, belong to a kind of mechanical dynamic seal device.
Background technique
In the prior art, the integrated type mechanical sealing mechanism of using as 2.2kw～7.5kw Submerged Motor Pumps, see shown in the accompanying drawing 1, it is mainly by the stationary ring in integral sealing box 1 and the sealing case 2, circlip for hole 3, rotating ring 4, O RunddichtringO 5,8,12, spring 7, runing rest 6, axle sleeve 10 compositions such as grade.Media end in the sealing case is identical with the seal form of motor side.This mechanical seal mainly by spring 7 cooperate with runing rest 6, runing rest 6 acts on rotating ring 4, rotating ring 4 acts on stationary ring 2, stationary ring 2 cooperates with the end face of sealing case 1 realizes mechanical seal.The 2.2kw of mechanical seal manufacturer production for many years～7.5kw Submerged Motor Pumps mostly selects for use materials such as silicon carbide, pottery, steel to make with the widely used rotating ring of integrated type mechanical seal, with any one rotating ring made in these materials, in actual use, find that an insurmountable always difficult problem is: use quiet, the rotating ring made with a kind of nonmetallic material situation that sealed working face is killed of appearing easily when mechanical seal is started shooting again after work, can rotate the cracked of ring when starting once more, thereby influence the working life of mechanical seal; Though the rotating ring that adopts steel to make can be avoided the generation of this situation, the antifriction performance but descends greatly, causes the reduction in working life.In case and sealing state is damaged, will causes pump motor to burn, and jeopardize the serious consequence of life safety.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, carry out improved and provide a kind of to prior art, improve sealability, and can adapt to Submerged Motor Pumps job requirement under abominable situation, make the Submerged Motor Pumps integrated type mechanical seal that is improved its working life.
The purpose of this utility model is finished by following technical solution, its main sealing case, stationary ring, circlip for hole, rotating ring, the O RunddichtringO, spring, runing rest, compositions such as axle sleeve, described rotating ring are to be made of chimeric being integral about metal rotation ring seat and the nonmetal rotation ring body.
Described metal rotation ring seat upper-end surface is provided with annular groove, and a nonmetal rotation ring body is embedded in the above-mentioned annular groove and with metal rotation ring seat and is connected.
Described nonmetal rotation ring body selects for use silicon carbide or pottery to make, and this rotation ring body (14) is combined in the annular groove (15) with the glue bonding of anti-at least 200 ° of temperature.
The mode that the utility model adopts silicon carbide or pottery to combine with metallic material is made compound rotating ring, has not only guaranteed the wear resistance of mechanical seal, because the outside is a metallic material, has solved the cracked problem of rotating ring again.Captured at one stroke a difficult problem for many years; Have simple and reasonable for structurely, easy to use, reliable, increase working life greatly, and Safety performance improves greatly, greatly reduces characteristics such as user's water pump repair rate and maintenance cost.
Description of drawings
Fig. 1 is the prior art constructions schematic representation.
Fig. 2 is the structural representation of compound rotating ring of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: the utility model belongs to a kind of improvement to prior art, as shown in Figure 1, it is mainly by the stationary ring in integral sealing box 1 and the sealing case 2, circlip for hole 3, rotating ring 4, O RunddichtringO 5,8,12, spring 7, runing rest 6, axle sleeve 10, following rotating ring 9, following stationary ring 11 compositions such as grade.The same with description of the Prior Art, media end in the sealing case 1 described in the utility model is identical with the seal form of motor side, the effect of its mechanical seal mainly by spring 7 cooperate with runing rest 6, runing rest 6 acts on rotating ring 4, rotating ring 4 acts on stationary ring 2, and stationary ring 2 cooperates with the end face of sealing case 1 realizes mechanical seal.Improvements of the present utility model be described rotating ring 4 be by metal rotation ring seat 13 and nonmetal rotation ring body about in the of 14 chimeric being integral constitute, see shown in the accompanying drawing 2.Specifically: described metal rotation ring seat 13 upper-end surfaces are provided with annular groove 15, one nonmetal rotation ring bodies 14 and are embedded in the above-mentioned annular groove 15 and with metal rotation ring seat 13 and are connected.Nonmetal rotation ring body described in the utility model selects for use silicon carbide or pottery to make, and the glue bonding of the anti-at least 200 ° of temperature of these rotation ring body 14 usefulness is combined in the annular groove 15.
Mechanical seal after the technology innovation more is applicable in the bigger operating mode of deep-well below 50 meters and sand content and uses.Use proof through the user, quality of product and working life improve greatly, bring up to more than 4000 hours from original 3000 hours service time continuously, and the user is reflected general good, is subjected to users' favor.
