Abstract

A kind of Pulp pump integrated spring mechanically-sealing apparatus, it will be in the threaded hole of holding screw precession spring base, spring base sealing ring is mounted in the seal groove of spring base, spring is mounted in the spring eye of spring base, seal ring of moving ring is mounted in the seal groove of rotating ring, anti-rotation groove alignment springs seat stop pin on rotating ring, circlip are mounted in the slot of rotating ring end, spring base and rotating ring are become one by circlip.Rotating ring, spring base, spring and seal ring of moving ring are integrated into moving ring assembly, can match with the stationary ring of any structure type.Maintenance is easily installed using multiple springs balanced type rotational structure, good integrity improves sealing service life.Spring does not reach medium and does not block two sealing rings in an airtight cavity by spring sealed, is driven by holding screw, firm reliable, stable drive.Double movable ring bearing structure of sealing ring makes rotating ring uniform force, and tracing ability is good, and end face remains best fit-state, guarantees the stability of mechanical seal working condition.

Description

A kind of Pulp pump integrated spring mechanically-sealing apparatus
Technical field
The utility model relates to a kind of mechanically-sealing apparatus more particularly to a kind of integrated spring mechanical seals of Pulp pump Device.
Background technique
Pulp pump is one of the key equipment in power plant and chemical industry production, and operational efficiency and reliability are largely The upper superiority and inferiority depending on sealing requires the reliability of sealing, service life, leakage rate and economy etc. also higher and higher, biography Filter medium clogging and non-integrated case are not able to satisfy above-mentioned requirements when spring mechanical sealing applications of uniting.
Summary of the invention
For the defect of conventional springs mechanically-sealing apparatus, the utility model provides a kind of for meeting high pressure operating condition, peace Radially, axially size is small for dress, carries out packaging by circlip, the novel Pulp pump integrated spring of one kind without being adjusted Mechanically-sealing apparatus.
Solving the particular technique measure that above-mentioned technical problem is taken is:
A kind of Pulp pump integrated spring mechanically-sealing apparatus, it is characterised in that: by 1 precession spring base 4 of holding screw Threaded hole in, spring base sealing ring 3 is mounted in the seal groove of spring base 4, and spring 6 is mounted in the spring eye of spring base 4, 2 seal ring of moving ring 5 are mounted in the seal groove of rotating ring 7, the 9 alignment springs seat stop pin 8 of anti-rotation groove on rotating ring 7, circlip 2 It is mounted in the slot of 7 end of rotating ring, spring base 4 and rotating ring 7 is become one by circlip 2, rotating ring 7, spring base 4, spring 6 Moving ring assembly is integrated into 2 seal ring of moving ring 5.
The utility model has the beneficial effects that the utility model is standardized designs, installation dimension meets HG/T2734-1995 And DIN28138 standard regulation.Spring base is to move by circlip with the advantages of movable ring structure matching design in the utility model Ring becomes one with spring base, and rotating ring, spring base, spring and seal ring of moving ring is made to be integrated into moving ring assembly, can be with any knot The stationary ring of configuration formula matches.Simplify the complicated kind of drive of original machine envelope in structure, dimensionally shorten installation dimension, Convenient for realizing installation in narrow pump chamber, over all Integration eliminates influence of the other factors to machine envelope decrement.Two on rotating ring A sealing ring contacts spring with medium and cooling water in an airtight cavity for spring sealed, and spring does not reach Jie Matter, spring do not block.It is considered as double movable ring bearing structure of sealing ring in design, makes rotating ring uniform force, tracing ability is good, end Face remains optimal fit-state.Axial dimension is compact as far as possible when design, operates more steady.Driving is passed by holding screw It is dynamic, firm reliable, stable drive.For clean medium, the secondary use that rubs is soft to hard (plumbago ------ carbon SiClx, tungsten carbide), right In impure, fouling, crystallization medium, rub secondary using firmly to hard (silicon carbide-carbon SiClx, tungsten carbide-tungsten carbide).It is mounted on diameter When occasion very small to, axial space, the advantage performance that mechanical seal is shown is prominent, guarantees the steady of mechanical seal working condition It is qualitative.

Specific embodiment
It elaborates with reference to the accompanying drawing to the utility model.
A kind of Pulp pump integrated spring mechanically-sealing apparatus, as shown in Figures 1 to 7, by 1 precession spring of holding screw In the threaded hole of seat 4, spring base sealing ring 3 is mounted in the seal groove of spring base 4, and spring 6 is mounted on the spring eye of spring base 4 Interior, 2 seal ring of moving ring 5 are mounted in the seal groove of rotating ring 7, the 9 alignment springs seat stop pin 8 of anti-rotation groove on rotating ring 7, card Spring 2 is mounted in the slot of 7 end of rotating ring, and spring base 4 and rotating ring 7 are become one by circlip 2, rotating ring 7, spring base 4, bullet Spring 6 and 2 seal ring of moving ring 5 is integrated into moving ring assembly, can match with the stationary ring of any structure type.Using the skill of this structure Art advantage is: 1. rotating rings are integrated into a spring assembly by circlip with spring base, are easily installed maintenance, good integrity mentions High sealing service life.2. two sealing rings in an airtight cavity, are unlikely to spring and medium and cooling spring sealed Water contact, spring do not reach medium, and spring does not block, and with seal ring of moving ring supporting structure, makes rotating ring uniform force, tracing ability Good, end face remains optimal fit-state.Guarantee self-centering, eliminates artificial installation error.
Fig. 3 is the scheme of installation of the utility model.Stationary ring 10 is pressed into gland 13 by magnitude of interference by stationary ring sealing ring 11 In, moving ring assembly enters axle sleeve 12 by spring base O snare and stationary ring 10 constitutes friction pair.Rotating ring contacts with each other with stationary ring and rubs Pair is wiped by suitable face pressure, and the pair that rubbed fits closely and dot encapsulation is leaked it, guarantees mechanical seal fortune stable for a long time Row.Stationary ring 10, stationary ring sealing ring 11, axle sleeve 12, gland 13 are not belonging to the component of the utility model, as just embodying when general assembly Component used when its connection relationship with the utility model.According to different working conditions, metalwork selects 2Cr13,304,316 Etc. materials;Spring using 304,316, the materials such as Hastelloy C alloys;Rotating ring stationary ring is using materials such as graphite, silicon carbide, tungsten carbides; According to material difference, use scope is wide.
For the utility model using the design of single-ended spring and multiple springs balanced type rotational structure, multiple springs compensation performance is good, end Face uniform load has excellent tracing ability simultaneously;(balanced mechanical seal refers to machinery of the loading coefficient less than 1 for balanced type design Sealing), influenced by chamber pressure it is smaller, be applicable in pressure limit it is wide;Modular designs, sealing installation are simple.
