Description
Technical field
The utility model relates to mechanical seal, is a kind of Submerged Motor Pumps mechanical sealing element.
Background technique
At the rotary pump that is used for carrying all kinds of flowing mediums, for the flowing medium that stops conveying along the slot leakage between revolution pump shaft and the pump case, Sealing must be set.In the prior art, the existing face seals that adopts, also be about to the pump shaft of rotation and the gap sealing of housing, be converted into rotation rotating ring of himself and the sealing between the stationary ring end face, but because the chemical property of the flowing medium carried of rotary pump has nothing in common with each other, think that the mechanical sealing element that all kinds of purposes rotary pumps are equipped with requires also just to have nothing in common with each other.Patent No. ZL00220829.6 as the Chinese patent literature publication, June 27 calendar year 2001 notice of authorization day, the model utility name is called " being used in the unit loading type double mechanical seal spare between revolution pump shaft and the pump case ", the sealing part constitutes the two-stage double seals by two dynamic and static ring, feature constitutes pedestal by axle sleeve and end cap, the axle sleeve periphery is the center with the stage clip, and both sides are followed successively by dynamic and static ring; Stage clip chamber with sealing; Establish front pressuring plate on the front-end face in stage clip chamber, ear end face is established rear fender.The utility model simple installation, sealing is reliable, the life-span is long.Can bear bigger forward and reverse pressure.
Owing to carry Submerged Motor Pumps explosion-proof, leakproof higher,, will contact breaking out of fire even blast with ambient air if there is small liquid medium to reveal to its used mechanical sealing element performance and quality requirement.And produce heat when pump shaft and Sealing run up, make the mechanical sealing element heating up, its sealing reliability variation.
Summary of the invention
For overcoming above-mentioned deficiency, the purpose of this utility model is to provide a kind of Submerged Motor Pumps mechanical sealing element to related domain, makes it solve the existing not good enough technical problem of like product sealing reliability.Its objective is and be achieved through the following technical solutions.
A kind of Submerged Motor Pumps mechanical sealing element, the sealing part comprises rotating ring, stationary ring, O RunddichtringO, push pedal, spring, spring seat, fastening screw trip bolt, stationary ring closely contacts by spring force with rotating ring, is provided with the O RunddichtringO between stationary ring and gland, the pump housing and rotating ring and the pump shaft; It is characterized in that described rotating ring, stationary ring are provided with two symmetrical groups, realize double seals with tight contact the between the rotating ring by stationary ring.Be provided with spring between two rotating rings, spring places in the spring seat, is provided with push pedal between rotating ring and the spring, rotating ring and push pedal place in the push pedal groove of spring seat, promote push pedal by spring and in the push pedal groove of spring seat, slide, promote rotating ring by push pedal again and closely contact, realize sealing with stationary ring; Described stationary ring connects the gland and the pump housing by driving pin, its objective is to allow stationary ring and gland fix, and prevents that stationary ring from rotating with pump shaft, makes stationary ring and rotating ring realize sealing by spin friction.Be connected by O RunddichtringO, fastening screw trip bolt between gland and the pump housing, make the gland and the pump housing produce sealing, prevent that impurity from entering the sealed chamber at rotating ring, stationary ring place.
A described side stationary ring is connected the pump housing by screw with pressing plate, and pressing plate is in order to prevent that pressure medium from releasing stationary ring.
Described spring seat connects pump shaft by screw, and the purpose that spring seat and pump shaft is fixing is to guarantee when rotating ring and spring seat are slidingly matched comparatively reliably, rotating ring disengaging spring seat or rotating ring and the stuck situation of spring seat can not occur.
The utility model adopts double seals to improve mechanical sealing performance, can effectively solve and carry explosion-proof, the existing unreliability of leakproof operating mode, and Seal cage is cooled off with circulating cooling liquid, prevent that effectively mechanical sealing element from influencing sealability because of elevated temperature deformation, thereby improved the working life of mechanical sealing element, effectively avoided the flowing medium accidental release and breaking out of fire.The utility model can be widely used in petrochemical industry and make the field, is fit to all kinds of chemical pumps and carries needs explosion-proof, the leakproof operating mode.
Description of drawings
Fig. 1 is a structure sectional view of the present utility model.
Above figure number and title: 1, driving pin, 2, stationary ring, 3, rotating ring, 4, spring, 5, spring seat, 6, push pedal, 7, the O RunddichtringO, 8, gland, 9, the pump housing, 10, pump shaft, 11, pressing plate, 12, fastening screw trip bolt.
Embodiment
Now in conjunction with the accompanying drawings, structure of the present utility model and working principle are further described.
This Submerged Motor Pumps mechanical sealing element is provided with two groups of rotating rings 3, stationary ring 2, and stationary ring connects the gland 8 and the pump housing 9 by driving pin 1, and wherein a side stationary ring is undertaken spacingly by screw and pressing plate 11, its objective is to prevent that pressure medium from releasing stationary ring.Be provided with O RunddichtringO 7 between rotating ring and pump shaft and stationary ring and gland, the pump housing, assurance liquid or gas can not revealed.Rotating ring and push pedal 6 place the push pedal groove of spring seat 5 both sides, and rotating ring and push pedal in groove for being slidingly connected, be provided with spring 4 in the spring seat, the elastic force of spring closely contacts rotating ring and stationary ring and realizes sealing, spring seat connects pump shaft 10 by screw, drive spring seat, rotating ring rotation when pump shaft rotates, make and realize reliable sealing by spin friction between rotating ring and the stationary ring.Be tightly connected by O RunddichtringO and fastening screw trip bolt 12 between the gland and the pump housing, its objective is to prevent that foreign matter from entering the sealed chamber at rotating ring, stationary ring place, influences the sealing between rotating ring and the stationary ring.
Working principle: the sealing of this Submerged Motor Pumps mechanical sealing element is the contact seal between two groups of rotating rings and the stationary ring, the sealing between rotating ring and the pump shaft, and the sealing between stationary ring and gland, the pump housing.Rotating ring closely contacts with stationary ring under the spring force effect, rotate with pump shaft owing to rotating ring again, and stationary ring is the fixedly connected gland and the pump housing, so be that spin friction realizes reliable sealing between rotating ring and the stationary ring.Reach between rotating ring and the pump shaft between stationary ring and gland, the pump housing and realize sealing by the O RunddichtringO.
