Description
Technical field
The utility model relates to the multistage filter of increasing material manufacturing and its preparation process more particularly to a kind of high-temperature nickel-based conjunctions
Golden multistage filter.
Background technique
Filter be it is a kind of stop opposite large scale impurity, realize in filter pulp be separated by solid-liquid separation, protection fluid system components
Device.The use of filter had not only guaranteed the subsequent smooth movement of filtrate, but also can protect the critical elements of fluid system, was fluid
The indispensable critical elements of system.
The filter medium of filter is the part of filtration, common to have metal, ceramics, high molecular material etc., wherein
Metal material because of high mechanical strength, it is corrosion-resistant with impact the advantages that, be widely used.Metallic filter media mainly has perforation
Metal plate, metal mesh, sintering powder and sintered fiber felt.Perforated metal can be punched by plate and is made, and metal net is to use
Wire is woven by certain rule.Metal plate and net use both surface filtration principle, and filter effect is guaranteed by aperture completely, is mentioned
High filtering precision needs reduced bore, and fluid resistance is caused to significantly rise.The specification of metal mesh is mainly by mesh size and wire
Diameter is determined, and is defined: percentage sieving area A0:
In formula: w is mesh size (mm)；D is wire diameter (mm).
Obviously, A0Bigger, then filter is smaller to the resistance of fluid.For nearly globular solids, the filtering accuracy of metal mesh
Depending on mesh size w.Therefore, increase A under the premise of keeping filtering accuracy (w is constant)0, it is desirable to reduce wire diameter d.
But required to meet pressure resistance, impact resistance and endurance of filter work etc., the structural strength of filter must be protected
Card., be by the bond strength between enhancing metallic fiber to solve this contradiction, it just can be with thinner wire diameter d
Reach higher metal mesh overall stiffness, realizes the target for reducing fluid flow resistance.
These filter mediums are made filter and require to carry out splicing sealing.The side that splicing can be compressed or be welded with metal plate
Method, but this can make the filtering material of interface section excessively fine and close, increase filtration resistance；Meanwhile the reliability of interface also directly affects
The filtering accuracy of filter.
For multistage filter, metal sintering fibrofelt has an effect of in-depth filtration, but the homogeneity that is sintered and
Stability cannot be guaranteed, can be sintered unstable fibre shedding problem, and high hole in use process under fluid impact
The fibrofelt integral strength of gap rate is lower, and fluid impact must be resisted plus support construction by using as filter medium, but be propped up
The presence of support structure increases flow resistance and filtering pressure drop.Metal mesh is the method for paved in multi-layers, and sintered fiber felt is then point
Layer pine dress, compacting re-sinter, this just determines that conventional metals multistage filtering dielectric thickness is larger, shape can only be it is better simply,
The quadratic surface (plane, cylindrical surface, circular conical surface) of small curvature.In order to reduce filtration resistance and pressure drop, usually only with increasing
The method of filter medium size, to increase filter area, but this causes filter overall volume to increase, in automobile, aerospace etc.
It is very unfavorable in the limited equipment in space.
Generally speaking, conventional metals filter designs and manufactures problem: (1) method process is more, the single-piece manufacturing cycle
Long, usual batch micro operations standard component can not adapt to the demand customized and iteratively faster designs；(2) it is difficult to produce simultaneously
Take into account the metal multistage filtering medium of high bond strength and rigidity, high filtering precision and low fluid resistance；(3) conventional multi-level filters
Device simple shape, size are larger, heavy；(4) it is limited to filter manufacturing technology, is often used ordinary metallic material, high temperature resistant is resistance to
Corrosive power is insufficient.
High-temperature nickel-base alloy has good stretch-proof, antifatigue, thermal fatigue resistance, Inconel718 alloy therein
With excellent corrosion resistance and good heat-resisting, creep-resistant property, it is employed successfully in the heavy corrosions such as turbogenerator pole
In end ring border.Filter is manufactured using high-temperature nickel-base alloy, its steady operation under severe corrosion and hot environment can be made.
Selective laser smelting technology (Select Laser Melting, SLM) melts metal powder using laser beam flying
It is enabled to reach metallurgical bonding, straight forming obtains the entity of nearly 100% consistency, is that one of metal increases material manufacturing technology is important
Direction.SLM manufacture part mechanical property with forge piece quite, it can be achieved that be better than 0.1mm precision, can satisfy big portion
Divide the manufacture requirement of conventional hardware.Meanwhile SLM technology can be processed and be closed including high-temperature nickel-base alloy, titanium alloy, stainless steel, copper
10 multiple material such as gold, aluminium alloy.
