The means that fluid of machinist factory cutting filters

Filter of type of 1 filter core filter of filter core type is commonly used the superfinishing that at machining claimed accuracy tall, useless bits becomes end state filters, or filter as 2 class rise filter use when precision. Filter precision 1 to 3 μ , of individual filter core filter ability is 0.

8l/min. Waste liquid is entered from the surface outside filter core, foreign matter is in by segregation filter core surface, foreign matter accumulates thicker more, when filter core cannot work normally, blow outwards from filter core interior compress air, cleared impurity, begin to filter afresh. Filter core pledges for nylon material, service life is very finite, it is 4 ～ on average 5 years. Interior of filter of filter core type is comprised by a lot of filter core, according to discharge different use different measure 2.

Of filter of adsorption layer of filter of 2 adsorption layer filter precision is 3 ～ 8 μ , the processing capability of only station filter is 1 ～ 600m3/h. The principle is action filters since the cellulose that uses adsorption to go up in filter core or diatomite. Filter core uses stainless steel steel wire to be made. Filter before beginning, medium is added inside preexistence filter (cellulose or diatomite) , make its adsorption is formed in filter core surface filter layer, filter next begin, waste liquid is entered from the surface outside filter core, foreign matter is in by adsorption filter core surface, clean liquid is taken out from filter core interior, should filter the ply of the layer is achieved when booking a value, clean unit begins the job to keep clear of to give attachment of filter core surface side by side, new loop begins. 2.

Filter of platen of 3 platen filter is used in car, mill commonly, auger, attack this kind to cut bits in bigger machining, onefold platen filter filters precision is in 100 μ above, filter precision is inferior. 2.

Filter of gravity of 4 gravitational filter is the gravitational action that relies on cutting fluid itself, make the liquid is after course filter cloth, useless bits and impurity stay on filter cloth and form filter cake gradually, as the addition of filter cake ply, liquid flow obstruction increases, fluid face rises. When fluid face rises to book the position, filter cake of eduction of filter cloth advancement, begin new circulation, one kind of clean liquid reuse filters means. Filter precision is 30 ～ 50 μ . The distinction with it and the biggest filter of vacuum punched tape in Yu Zhen empty filter relies on pump to come draw-out and clean liquid, vacuum is formed inside clean fluid box, liquid velocity of flow is rapid. Gravitational filter control is simple, and vacuum filtraction implement control system is complex, accurate, automation rate is high. 2.

1 form summarizes filter of vacuum punched tape to apply to most machining industry, it is the commonnest concentration filters system. Project middling often cooperates a few times to rise use, according to systematic precision and discharge requirement, configure sometimes for a thick filter an essence filter, configure sometimes for a thick filter two essence filter. Whole construction of system is complex, cover an area of an area bigger. 2.

1 precision control filters precision can undertake controlling according to need, it is 15 ～ normally 80 μ , limits of stand-alone discharge design is in 15 ～ 1800m3/h, precision limits and discharge range are bigger. The cutting fluid inside the system can circulate hourly 7 ～ 10. Filter bulk is decided by discharge, but width depends on the width of filter cloth. Normally thick filter width 1.

5m left and right sides, width of filter of essence of life 2.

5m left and right sides. Of this kind of filter filter precision relies on filter cloth and filter cake to control, what have main effect among them is filter cake. Corrupt fluid abandons bits grain to be left on filter cloth when passing filter cloth, form layer of filter broken bits, be called " filter cake " . As the grow in quantity of useless bits grain, some stop in surface of layer of filter broken bits, make filter cake is added thick, some enter interior of filter broken bits, reduce gap of filter broken bits, increase filter cake density. Thicker, density jumps over filter cake big, filter precision is taller. Rising filter precision while the obstruction that the liquid flows can increase, box vacuum spends clean fluid to be able to greaten. Spend when vacuum achieve when booking numerical value, valve open, punched tape is ongoing, eduction filter broken bits, begin new circulation. Clean liquid carries treatment facilities to use from clean fluid box. 2.

2 medium are chosen filter medium often is used without spin cloth, but without spinning cloth cannot be used circularly, and can cause environmental pollution. A few manufacturer use a loop to pass screen now, it is material of a kind of nylon filters character medium. Cast-iron treatment line filters the circulation that the system uses crosses screen to be able to use 2 ～ 3 years, other adds workpiece live screen service life longer. Pass screen price circularly more expensive, every meters price is without what spin cloth 250 times the left and right sides. 2.

3 configuration filter equipment can provide cooling circulatory system, the cutting fluid temperature after making filter is stable, ensure the spare parts machines quality. Still need to provide the unit that remove oil, in using purify liquid oleaginous. The system distributes stock normally automatic, semi-automatic, hand is moved and the holiday circulates 4 kinds of mode. The system needs to configure a few even ten pump, have a plenty of the systematic pump that uses when normal production, with will keep systematic pressure; Have a plenty of sewage pump, use when blowdown water; Have a plenty of what when the system is safeguarded, use; Still have a plenty of reserve pump. Be worth what carry is holiday loop pump, use holiday loop pump when product line stops to machine, maintain liquidity of the liquid inside the system, managing specific power consumption while prevent cutting fluid metamorphism. Circulate except the holiday beyond pump, the power of other pump is very great, according to system flow rate different, the power of only station pump is great can amount to about a hundred kilowatt. For example, one steam group does not have stannic diesel engine factory, one of motor product line filters system flow rate is 2840m3/h, share 10 pump, the power of every pump all is 90kW. Need of the chroma of fluid of the cutting inside the system, quality detects everyday control, increase additive to prevent liquid metamorphism. Filter deserves to have unit of automatic fluid infusion normally, add former fluid or water appropriately, make sure chroma of the liquid inside the system is in permissive limits, the chroma that often uses is 90 ％ ～ 95 ％ . Cutting juice former juice is liquid of a kind of not easy combustion, inexplosive, chemistry is stable. Can small lot is deposited inside the workshop, OK also large quantities of quantities are deposited inside storeroom. Of cutting fluid deposit a requirement ventilated be close friends, best control is in temperature 40 ℃ of 0 ℃ ～ . If use entrance cutting liquid, plus science maintain, can use 2 years, longer even. The property of homebred cutting fluid is very not at present stable still, production uses time slightly a few shorter, the price also relatively the petty gain of the entrance. If the precision of the requirement is tall, filter of vacuum punched tape is OK still cooperate to use with the filter of other form, rise effectively filter precision. Nextpage2.

6 hydraulic Xuan shed filter hydraulic Xuan sheds what filter uses is physical principle, object place suffers the size of centrifugal force and object weight to concern. High speed current enters round cone-shaped filter with tangent direction from the mouth that enter fluid, form Xuan to flow. Solid grain does circumnutation together along with the liquid, because solid grain proportion is more than a liquid, below centrifugal force effect, the solid in athletic process moves more easily to container wall, encounter next container wall is backward sliding, from eduction of cuttings pick-up mouth. Whirly edge drops by the side of the liquid, one is formed in filter interior cylindrical meiobar, when the current circumgyrate radius that instantly falls and low-pressure and columnar radius are identical, enter aeriform influence from cuttings pick-up mouth and current is moved up, from the eduction of mouth giving fluid above filter. Structure of this kind of filter is simple, low-cost, filter precision is tall, achieve 10 ～ 50 μ , commonly used Yu Qing washs machine or stand-alone to filter. Hydraulic Xuan sheds filter to having firm demand to entered liquid discharge, flow is too little the Xuan that forms ideal effect hard flows, detached effect is poor; Discharge crosses big liquid to be full of filter to cannot form Xuan to flow, separate action is less than since. Additional, filter the effect and foreign matter density are having immediate concern, the effect of depart of foreign matter grain that the foreign matter grain of small density does not have big density is good. For example, of cast-iron grain filter the effect wants grain of excel aluminium alloy. 2.

Filter of magnetic force of filter of 7 magnetic force is to use magnetism to be opposite guide the attraction of magnetism grain action, has used liquid has shed magnetic field, guide magnetism grain is left, the others filters through a kind means. Basically use in the light of scrap, can use this one characteristic to undertake depart to scrap. Be machined for example a component that already iron has aluminium again, can use magnetic force filter to come out scrap depart to be collected alone first, next reuse other filter filters. Of 3 filter offer, the means that answer fluid this one part is to basically be aimed at concentration to filter the system. The feed flow between filter and equipment, means that answer fluid has a lot of planting, adoption means differs to the influence of workshop structure. Some filter are decorated in basement, some decorating go up in workshop ground level ground. If decorate,is ground channel with respect to need in basement, have ground channel, must want to designing initial stage to consider the position of ground channel, deepness, because the position of ground channel, deepness is met,produce very big effect to workshop post. If line of ground channel center is apart from the central dimension of post not to exceed 1 meter, the subterranean structure of so channel is afraid have to mix the subterranean structure of workshop post a construction. If post and ground channel because a variety of reasons cannot at the same time the word of construction, both and mutual interference had better avert in design phase, otherwise if will bring a trouble to construction. Initial stage is designed in the factory, if be used certainly wet the plan of treatment, building, structure and public each major considers the feed flow, means that answer fluid to be opposite with respect to need this professional influence, accomplish against a rainy day, as far as possible the program reachs the designated position. Introduce a few kinds of common concentration to filter below the system uses for, the means that answer fluid. 3.

Channel of the feed flow in 1 sky, ground answers fluid machine tool to decorate go up in workshop ground level ground, filter is decorated inside basement. Every machine tool sets mouth of bits having a platoon, the cutting fluid after using flows into ground channel from the mouth that discharge bits, circumfluence of classics ground channel arrives inside filter, the cutting fluid that filters clean supplies a machine tool to use from the conduit in sky below pressure action. Ground channel is 400mm ～ 500mm normally wide, have 1 ％ ～ the gradient of 2 ％ , the gradient that domestic manufacturer designs often takes 2 ％ . Deepness of place of ground channel start is 400mm of subterranean 300mm ～ deep, when product line length is longer, most in can be as deep as 2.

5m above. Setting of 6 ～ 8m develops the every other inside ground channel bits mouth. The action of strong bits mouth is to use clean liquid to erode ground channel is bottom, prevent to abandon bits to pile up in ground channel bottom. Turning of every ground channel also needs to set strong bits mouth. Canal pouring bit is in charge of from feed flow derivative, to decrescent of diameter of ground channel inner tube, raise strong bits to provide pressure. channel most in install one leak to dominate a powerful person or family, if ground channel has any leak,can in time feedback information, prevent groundwater pollution, managing the sources of energy. The subterranean spy form that this kind of means that answer fluid involves is the most complex, the position of hole of ground channel, ground, deepness is the problem that structural major cares most. When subterranean spy compose and workshop post when the distance is closer, workshop post foundation must consider the impact of subterranean spy compose, often can adopt the method that sinks post foundation to avoid ground channel and post foundation to be interfered each other. Of net of canal of public and professional underground arrange the issue that also must want to consider ground channel, as soon as possible avoids the mutual across between ground channel, reduce the trouble of construction as far as possible. Of ground channel decorating is as parallel as product line normally, also can have a channel with vertical section (it is sometimes advocate channel) . The deepness that raise channel is more shallow, advocate channel deepness is deeper. Additional, because concentration filters system flow is normally larger, way of canal of feed flow canal is very so old also, can amount to 400mm bigger even. Differ according to system flow rate, feed flow canal is two sometimes. Still have the conduit in the sky such as canal of blowdown canal, feed pipe, air feed, specific canal diameter and weight must want when filter equipment orders goods, ability may be final after the design affirmatory, but these load are designed in the factory at the beginning of, when condole nods load, considering workshop must want to consider to go in. Ground channel is through type a kind, one kind is by of buy type. The ground channel of through type is V form chamfer below corresponding equipment, cell body and ground channel are interlinked; The ground channel of buy is normally by pass from the back of equipment, the fluid chamfer that is interlinked with ground channel is at the back of equipment. Ground channel is general make it open drain, steel cover board is installed above. Channel of through type ground does not need to install cover board in equipment lower part, channel of buy type ground needs cover board entirely by. Country's common ground channel form has 3 kinds: Channel of A, scraper: Common machine at doing type, also can use at wet treatment discharges bits. Channel bottom is flat bottom, in-house setting has the conveyor such as scraper catenary. B, fork pulls channel: Commonly used the system discharging bits that abandons bits at conglomerate form, channel interior setting has broach. Stormed crack of form of C, U: Ground channel becomes U entity, by 3 board composition, two sidewall 6mm of each one 4 ～ is thick, bottom large board of a 8mm, solder and become. This ground channel has certain gradient, and in-house setting has strong bits opening. This kind of channel is in wet in processing the system that discharge bits most common. Because filter equipment volume is large, interior contains full cutting juice, the ground hole that places filter so needs to consider foundation to bear the weight of the requirement of force. Ground hole bottom and sidewall often need to have bury beforehand, bottom buries I-steel to use tone to make the same score equipment beforehand, sidewall buries armor plate beforehand the installation of convenient steel component. 3.

Force of concentration of the feed flow in 2 sky, underground, empty middling pressure answers fluid machine tool and filter to be decorated go up in workshop ground level ground, decorate below the ground have the pot that answer fluid. Every equipment has the opening that discharge bits, the cutting fluid after using from eduction of the mouth that discharge bits, classics ground channeling enters the canister that answer fluid, arrive when fluid face when booking height, open of the pump that answer fluid works, waste liquid issues direct regurgitate filter in pressure action, clean liquid sends to the machine tool via the conduit in sky again. This kind of means that answer fluid applies to the machine tool that U form decorates, can reduce ground channel length, reduce greatly channel amount. Setting of the canister that answer fluid is under the ground, fluid canister is answered in estimation the minorrest volume when normally effective cubage can contain consideration fluid canister 40 seconds plant a service equipment (longer even) the gross that discharge fluid. Every canister that answer fluid serves 3 facility, if the discharge of every equipment is 400l/min, so the effective volume of the canister that answer fluid is the minorrest for 0.

8m3. The pump answering fluid that uses with form a complete set of the canister that answer fluid needs to install two, use one equipment. It is OK on the ground that filter itself is decorated reduce workload of subterranean spy compose, equipment is decorated rise more agile also. 3.

The gravity in concentration of the feed flow in 3 sky, underground, sky answers fluid this kind of means that answer fluid and " force of concentration of the feed flow in sky, underground, empty middling pressure answers fluid " the structure is similar, what the biggest distinction depends on should answering fluid means to basically be relied on is gravitational. After waste liquid comes out to flow into ground channel from equipment, the canister that answer fluid is entered in gravitational action indelicacy, when fluid face rises to book a value, answer fluid pump open, the liquid is flowed into fluid chamfer is answered in sky, answer filter in gravitational action indelicacy next. The characteristic with this kind of the most striking pattern that discharge fluid is there is the chamfer that answer fluid in sky, be like is to will answer fluid ground channel to wear like be in sky. Fluid chamfer is being answered in sky contain certain gradient, "Force of concentration of the feed flow in sky, underground, empty middling pressure answers fluid " the canal that answer fluid is in sky is a level, go up in this bit both also differ somewhat. 3.

Force of the feed flow in 4 sky, empty middling pressure answers fluid, whole area to decorate this kind to decorate means the biggest advantage is all equipment decorate entirely in ground above, an equipment provides an unit that answer fluid. Those who do not have and so on of hole of ground channel, ground is special compose, simple, equipment decorates workshop form environment of agile, work is easy. Waste liquid comes out to enter the canister that answer fluid from equipment, fall to return filter directly in effect of strength of the pump pressure that answer fluid. The cutting fluid that filters clean is supplied from the conduit in sky every equipment is used. The requirement of this means that answer fluid to equipment itself and afore-mentioned all sorts of kind are different, ask every equipment distributes stock the respective canister that answer fluid and the pump that answer fluid. Some equipment adopt the measure that imposes tall lathe bed, equipment below the fluid box of make it whole is used as the canister that answer fluid, deploy the pump that answer fluid. Also some equipment are setting of the whole apparatus that answer fluid on the side of the machine tool. Use this kind of means that answer fluid to be able to increase the amount of the conduit in sky. An equipment answers fluid conduit, although the weight of a conduit is very light, but the load that can increase workshop of the amount to a string of 1 the dot needs a consideration undoubtedly greatly. 3.

The gravity in the feed flow in 5 sky, sky answers fluid, whole area to decorate this kind means and " force of the feed flow in sky, empty middling pressure answers fluid, whole area to decorate " exclusive differentia is this the means that answer fluid is pressure and gravity be united in wedlock. After waste liquid flows into fluid reservoir from equipment, gravity is entered to answer fluid chamfer below pressure action, answer filter in gravitational action indelicacy next. Gravity answers fluid groove and " the gravity in concentration of the feed flow in sky, underground, sky answers fluid " gravity answers fluid chamfer identical. All equipment also are to be decorated entirely in ground above. A few kinds of fashion that above of 4 last words introduces eliminate the form that uses the gravity in sky to answer fluid chamfer beyond, a few kinds of means of other all commonner. Wet the cutting fluid of treatment filters the choice of form, filter and the choice of the means that answer fluid are concerned with a variety of elements, every kinds decorate means to have the advantage of its oneself and the drawback that avoid hard, conclude qualitatively impossibly which kinds of means is best, can be specific project only concrete analysis, a kind of the properest way is chosen after be being compared integratedly. This asks our craft and earth are built, public each major cooperates cheek by jowl, communicate adequately, solve the problem that appears possibly in the first phase of the design.
