Description
Technical field
The present invention relates to a kind of encapsulant, belong to and have the axostylus axostyle of rotary motion to seal for pump class, valve, decelerator etc.
Field of material technology.
Background technology
The existing pump packing using sizing specification, is filled in the stuffing-box of pump more.Although the more letter of this sealing means
Just, a certain degree of effect can be played, but between this type of packing and pump shaft, still there is a certain degree of friction, even if
The packing that coefficient of friction is the least, it is also surprising with the caloric value of axle contact position, therefore generally requires cooperation cooling system
Cooperation.Long-Time Service is also quite serious to bearing wear simultaneously, and bearing can be caused permanent injury by Long-Time Service.
Muddy packing------is also referred to as: " pouring-in soft packing " is equipped with special grease and profit by a new generation's high-performance fiber
Sliding, refined senior " packing " soft packing, arbitrary dimension, arbitrary shape, easily install, by special High Pressure Gun
Just can directly inject, it is not necessary to as traditional packing, need precut, the packing box seal of any size can be suitable for.
Mechanical seal is the most advanced compared with for first two bearing seal mode is the gland seal device of a kind of rotating machinery.Such as
The equipment such as centrifugal pump, centrifuge, reactor and compressor.Owing to power transmission shaft is applied in inside and outside equipment, so, between axle and equipment
There is a circumferential clearance, the medium in equipment by this gap to outward leakage, if pressure subatmospheric in equipment, then empty
Gas is revealed in equipment, it is therefore necessary to have one to stop the gland seal device revealed.The kind of axle envelope is a lot, owing to mechanical seal has
There is leakage rate few and the advantage such as life-span length, so mechanical seal is in the topmost sealing side of these equipment in the world today
Formula.End face seal is named again in mechanical seal, is defined such that and is perpendicular to rotation by least one pair of in relative national standards
End face keep under the cooperation of fluid pressure and the effect of compensation mechanism elastic force (or magnetic force) and auxiliary seal laminating and phase
The device preventing fluid from leaking that slip is constituted.
Mechanical seal is by a pair or several to being perpendicular to the end face of axle work slip relatively at fluid pressure and compensation mechanism
Elastic force (or magnetic force) effect is lower to keep laminating and is equipped with auxiliary seal and reaches the gland seal device of Drain Resistance.Conventional machinery seals structure
By stationary ring (stationary ring), rotating ring (rotating ring), flexible member, spring base, holding screw, rotating ring auxiliary seal ring and static
The element compositions such as ring auxiliary seal ring, stop pin is fixed on gland to prevent stationary ring from rotating.Rotating ring and stationary ring are often
Also whether can have nose balance ability according to them and be referred to as compensating ring or uncompensated ring.Use middle rotating ring auxiliary seal ring
Easily senile abrasion, loses effect.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, propose a kind of resilience effect more, more resistant to mill,
Pollute less mechanical seal auxiliary sealing member material.
The present invention solves that the technical scheme that above-mentioned technical problem proposes is: a kind of mechanical seal auxiliary sealing member material
Proportioning number is as follows: mixed rubber 75-95, melamine 1-2, zinc oxide 1-2, molybdenum bisuphide 1-2, double ten four carbon alcohols ester 4-6,
Chlorinated paraffin 6-8, polyethylene wax micro mist 4-5, TBAB 1-2, dithiodiisopropyl xanthate 1-2, age resistor
1-2, butyl polyacrylate 2-3, lime stone 5-7, terpinol 1-2.
Described mixed rubber is to be mixed by the Polyether urethane rubber that weight ratio is 1:9 and fluorubber.
Described lime stone is the white lime containing a small amount of quick lime impurity.
Described age resistor is poor efficiency age resistor, typically uses phenol antiager.
The preparation method of described mechanical seal auxiliary sealing member material is as follows:
(1) dispensing: weight portion as described in claim 1 weighs raw material, and mixes；
(2) banburying: the raw material that will mix, puts into rubber internal mixer banburying 10-20 minute, and banburying temperature is: 85-100
℃ ；
(3) in blocks: the material through banburying to be taken out, puts into friction machine and be rolled into film；
(4) extrusion: by step (3) film, use extruder for shaping；
(5) sulfuration: step (4) moulding material being put into the mould of vulcanizer, molds, vulcanize 6-15 minute, pressure is
20Mpa, temperature is 120-150 DEG C, then opens mould, and get product material.
The present invention uses technique scheme to provide the benefit that: because selecting mixed rubber Oil repellent higher, therefore make
Rubber is the most stable, the most oxidizable and the phenomenon of ageing of rubber occur, has more preferable resilience, corrosion resistance and wear-resisting
Property, service life is longer, needn't often change, although use poor efficiency age resistor, but the more environmental protection that has fewer environmental impacts,
Even if occurring that leakage situation also to causing significant damage, and will not select mixed rubber fluorine-containing religion height itself, the most more
Stable, it is difficult to oxidized or displaces, thus without the normal use affecting product itself.
Detailed description of the invention
Embodiment
A kind of mechanical seal auxiliary sealing member material of the present embodiment, proportioning number is as follows: mixed rubber 75-95, melamine
