Description
Technical field
The present invention relates to a kind of titanium alloys technology for making, particularly a kind of titanium alloy filter device.
Background technology
Filter is a mini-plant of removing small amount of solid particle in the liquid; can protect the operate as normal of compressor, pump, instrument and miscellaneous equipment; after entering the filter cylinder that is equipped with the certain specification filter core when fluid, its impurity is blocked, and the filtrate of cleaning is then discharged by filter outlet.If it is installed in series at other position of the inlet or the systematic pipeline of pump, then both can prolong the service life of pump and miscellaneous equipment, can guarantee the safety of whole system again.Filter has been widely used in fields such as metallurgy, chemical industry, oil, papermaking, medicine, food, mining, electric power, ocean engineering.
But the general material that adopts of the filter that uses both at home and abroad is carbon steel, copper and stainless steel at present, and service life is short, generally all is lower than 6 months.The filter that the enterprise that has adopts stainless steel to make only uses and just scrapped in 5 months, must stop to produce, and frequently maintenance or more exchange device bring big economic loss to enterprise.
At above-mentioned situation, when the design filter for installation, must consider the problem of filter corrosion-vulnerable, in the past at the situation of filter corrosion-vulnerable, filter interior is reserved corrosion allowance during the design filter, with the service life of increase filter, but only can prolong service life about two months, effect is also not obvious.
Summary of the invention
Technical problem to be solved by this invention provides a kind of titanium alloy filter device, and this device adopts the erosion resistant titanium alloy new material, can obviously improve the corrosion resistance of filter, prolongs the service life of filter.
For the purpose that realizes solving the problems of the technologies described above, the present invention has adopted following technical scheme:
A kind of titanium alloy filter device of the present invention, form by housing, axle, handle, baffle plate, filter core trim ring, sewage draining exit gland, feeding port gland, stud, plug screw plug, filter core, seal washer, bolt, nut and filler, be characterised in that: housing, adopt the TA5 titanium alloy in handle, baffle plate, filter core trim ring, sewage draining exit gland, feeding port gland, filter core etc.; Axle, stud, plug screw plug, bolt, nut etc. adopt the TC4 titanium alloy.
A kind of titanium alloy filter device of the present invention, its concrete technical scheme can be: described seal washer adopts polyfluortetraethylene plate, and filler adopts the polytetrafluoroethylene (PTFE) braid.Technical scheme is that described seal washer polyfluortetraethylene plate is the 3mm plate more specifically; Filler adopts the polytetrafluoroethylene (PTFE) braid, and its cross section is 6mm * 6mm.
A kind of titanium alloy filter device of the present invention, its concrete technical scheme can also be: described axle, feeding port gland, stud, plug screw plug, packing ring, bolt, nut adopt titanium alloy to forge excellent machined and form.
A kind of titanium alloy filter device of the present invention, its concrete technical scheme can also be: described housing, handle, baffle plate, filter core trim ring, sewage draining exit gland, filter core are titanium alloy casting, formative method adopts the machined graphite mould, and adopt high temperature insostatic pressing (HIP) to eliminate internal defect in cast, machined forms then.The manufacturing process of titanium alloy casting as shown in Figure 2.
Above-mentioned technical scheme also can make up mutually or combination, thereby reaches better technique effect.
A kind of titanium alloy filter device of the present invention, its concrete design principle is:
1, because the medium of filter is a seawater, has stronger corrosivity, adopt carbon steel or stainless steel to make filter, the necessary corrosion allowance of filter interior, to prolong the service life of filter. because titanium alloy material has fabulous corrosion resistance, when the design titanium alloy filter, filter interior needn't be reserved corrosion allowance, can reduce the wall thickness of filter, alleviate the weight of filter apparatus.
2, use stainless steel to make filter core, the stainless steel filter core easily corrodes in the seawater medium, can cause the filtering holes on the filter core to diminish, and causes the filter water amount to reduce, the pressure loss strengthens when work during filtration, must reserve certain water surplus of crossing during the water amount of design filter core; Adopt the good titanium alloy material of corrosion resistance to make filter core, filtering holes can be because of corrosion diminish, and does not need to reserve water surplus during the filter core of design titanium alloy filter, can shorten the length of filter core during design, and filter apparatus length is corresponding also can be shortened.
After all parts manufacturings of titanium alloy filter machine, test, assemble after the assay was approved.Carry out seal tightness test after assembling is finished, do not have the seepage phenomenon to take place, deliver to customer to use.
Titanium alloy filter (calculating by 10 years service life) and carbon steel filter cost of use compare as follows:
70,000 yuan of the procurement prices of titanium alloy filter, life cycle 10 years, use cost was 70,000 yuan in 10 years;
10,000 yuan of the procurement prices of carbon steel filter, life cycle 0.5 year, use cost was 200,000 yuan in 10 years.
As can be seen, though the purchase cost of titanium alloy filter is higher, but use cost obviously reduces than the carbon steel filter, the use cost of titanium alloy filter is 35% of a carbon steel filter use cost, can obviously save production cost, this does not comprise that also the carbon steel filter in use changes filter or filter core and cause and produce the economic loss that stops to cause.
By adopting technique scheme, titanium alloy filter of the present invention has the following advantages:
1. titanium alloy filter has fabulous corrosion resistance, can prolong the service life of equipment greatly;
2. corrosion allowance need not reserved in inside when designing filter, has alleviated the weight of filter apparatus;
3. the specific strength height of titanium alloy can reduce wall thickness during the design filter, can reduce the weight of equipment;
4. use titanium or titanium alloy to make filter core, filtering holes diminishes when having avoided the filter core corrosion, and the situation that causes the filter water amount to reduce takes place, and has reduced the pressure loss when filtering effectively, prolongs filtration time, reduces maintenance cost.
5. use titanium or titanium alloy to make filter core, do not need to reserve water surplus during the filter core of design titanium alloy filter, can shorten the length of filter core, filter apparatus length is corresponding also can shorten (during the design titanium alloy filter, the length of filter apparatus and the length of filter core have reduced 120mm), reduce the space occupy-place of filter for installation.
