Dheecaanka goynta (coolant): soocidda, codsiga

habka Metalworking waxaa ka muuqo la xiriira khilaaf xoogan oo u dhexeeya dhacdaa workpiece iyo qalab. Tani gaar ahaan waa cad marka jeestay oo axdi qarameedka ka shaqeeya, marka qalab ay tahay mid aad u kulul, extrusion qabow, xawaaraha sare ee degtey rookaha. khilaaf xooggan oo ku kordhinaya Duugga dhicis ah ee qalab, lahayo ku caagga ah ee workpiece ah, guryaha isbedelka ee biraha ay sabab u tahay kulayl. In la yareeyo ciidamada khilaaf u baahan yahay dareere gaar ah goynta (coolant) iyo hoos heerkulka.

Beegyada uu coolants soocidda

coolants soocidda General qaadeen dhowr xuduudaheedu:

• On asal ahaan ka mid ah qaybaha ugu. coolant saliidda soo saaray, kaas oo ku salaysan yihiin saliidda shidaalka, xoolaha ama dufanka cuntada.
• By jidka isku xira. Emulsol - wax soo saarka dhammeeyayna ay nolosha shelf dheer ama emulsion farsamo, loo diyaariyey isla markiiba inta aan la isticmaalin ee shancosbitaal sidii GOST.
• On oo xuduudaheedu jirka iyo farsamo - nafwaayay, tirada acid, dhibic flash. Dabeecadaha dambe sababa codsiga oo saliid ah coolant for Gurdanka kulul.
• Sida laga soo xigtay beerta codsiga. Waxaa soo saarta noocyada kala duwan ee coolants xaaladaha hawlgalka kala duwan ee codsiga. dheecaan goynta dardaro hawlgallada lahayo ku caag ah, coolant for lathes ama mashiinada axdi qarameedka.

The biyo dardaro coolant L universal EFELE CF-621 sida shancosbitaal ah loogu talagalay machining ee birta kabka, steels, oo ay ku jiraan ahama iyo daawaha, titanium, aluminium iyo Alloys copper. coolant Tani saarka Ruush uu leeyahay midab hurdiga ah iyo caraf udgoon karamell wacan. Waa kuma jiraan formaldehyde, chlorine iyo amines sare, si ammaan ah aadanaha. Sameeyey qaybaha dardaro dheeriga ah (15%) macdanta Halabuurka saliidda, emulsion waxay leedahay qiimo jaban ah, dabeecad u ah wax soo saarka macdanta. Biostability iyo waxqabadka EFELE CF-621 ogolaan xal Biraha machining ka yar marka la barbar dhigo uruureen kale coolant.

Qoondaynta of Halabuurka coolant

On Halabuurka ee coolant kala ah noocyada soo socda:

• Oil - daawooyinka ka mid ah qaybaha kuwaas oo immiscible biyo. emulsion saliid Base waa la shito, macdanta ama saliida shidaalka (60-95%). Si kor loogu qaado waxtarka anti-Duugga, khilaaf, daxalka ee halabuurka ka mid ah lagu daro kala duwan iyo inhibitors. emulsion Oil hantiyi guryaha cabbeeyo fiican. Loo isticmaalo biraha jilicsan ee hababka qalliinka fudud.
• Macdanta - saldhig ka saliidda sameeyey by hydrogenation horseed. Si loo kordhiyo waxtarka lagu daro waxaa ka mid ahaa ka dufanka, chlorine, baaruud, xeryahooda fosfooraska. darey waxaa loo isticmaalaa in noocyada sida bir, sida: steel jarida, aluminium, naxaas ah, threading, dawo la'aan shaqo alloyed steels.
• miscible Water - xal aqueous ku salaysan saliid macdanta. walxuhu waxay leeyihiin guryaha qaboojinta aad u fiican iyo sumoobo yar yahay, laakiin waxqabadka cabbeeyo hooseeyo. Baaxadda - iftiinka iyo waajibaadka dhexdhexaad jeestay copper iyo naxaas ah, axdi qarameedka iyo qodista ee dhammaan noocyada kala duwan ee biraha non-ferrous, shiidi iyo feeray steel.
• Dardaro iyo semisynthetic - isku dar ah oo biyo ah, surfactants, biyo polymers milma, anti-afkuu oo lagu daro bakteeriyada, inhibitors daxalka. Si loo kordhiyo lubricity ee darey dardaro ayaa sidoo kale maamula daro antiwear.
• Emulsions - darey uruureen sare ee Qurub kala firdhiyey. Yaree xaddiga ay xirtaan qalab iyo qalabka ee dhammaan hawlgallada metalworking.

Qaabka iyo hab of tallaabo of coolant ah

Isticmaalka baahsan ee coolants in geedi socodka processing biraha ay sabab u tahay kala-ool ah oo ka mid ah meelaha ku xoqeen ayay ka mid ah workpiece iyo qalab iyo yareeyaan heerkulka. The coolant ugu waxtarka badan waxaa ka mid ah qaybaha soo socda ee ay ka kooban:

• The salaysan saliidaha dardaro ama dufanka xayawaanka.
• Lagu daro in la kordhiyo Duugga ah frictional iyo qaab cadaadis ba'an.
• Qaybaha, ka hortagga Halabuurka delamination inta lagu guda jiro kaydinta.
• Lagu daro in looga hortago in ragaasi iyo halaag.
• Qaybaha, yaraynta afkuu iyo qoynta ah meelaha in biraha.

Isticmaalka coolant

dheecaannada Metalworking waxaa loo isticmaalaa si saliidayn ku tiinbiyo oo deegaanka shaqada ee biraha. Guryaha coolant ogol yahay si loo yareeyo khilaafka aaga daaweynta, taasoo ay xirtaan qalab ah, kordhinta tayada sheyga by hagaajinta xoogga geedi socodka iyo, sida natiijo ah, wax soo saarka guud.

Sababo la xiriira guryaha cabbeeyo wanaagsan ee coolant u yaraynaysaa ciidanka frictional dhexeeya dusha workpiece iyo laayeen goynta of qalab ah, khilaaf ee cut lakabka bir ah. labeen farsamo qaarkood waxay leeyihiin kiimikaad kor u hoos u ma aha oo kaliya ciidamada frictional, laakiin sidoo kale ciidamada goynta. Inta badan coolant - surfactants leh guryaha adsorption sare. Waxay awoodaan inay sameeyaan filim ah oo deggan on dusha biraha, kaas oo aad u yaraynaysaa khilaaf jira. Qaar ka mid ah lagu daro surfactant gaar ah leeyihiin on biraha "aaladdda" tallaabada. taagoo ifafaalaha lagu daro sida dhicin microcracks in dusha biraha, sida waslad, oon ku wiiqday bond u dhexeeya Qurub mid ah waxyaabaha la. Sayidka, coolant "caawisaa" qalab shaqada si ay u dhinto daaha ka biraha salka.

The darey coolant ugu caamsan ee qalabka mashiinka

lathes Metalworking iyo mashiinada axdi qarameedka waxaa lagu soo saaray cabitaanno soo socda:

• Emulsoles ku salaysan saliidaha macdanta iyo batroolka.
• ✰Saliidda qubeyska la acids dufan dardaro.
• Soo jeestay oo shaqada axdi qarameedka, bixinta processing-xawaaraha sare ee steels ahama iyo daawaha, soo saaray si waafaqsan GOST 38.01445-88. Ujeeddooyinkan, la siiyaa darey synthetic taas oo ku salaysan yihiin Tællelyset alcohols vysokoatomnye saliid triethanolamine.
• Sulfofrezoly - aadka u daahiriyey saliidda isku dar ah oo xeryahooda baaruud-ka kooban. Ha ku jira biyaha, alkalis, acids. coolant noocan oo kale ah mashiinada wax ku ool ah si loo yareeyo khilaafka, ma keenaan daxalka.

Codsiga of coolant daaweynta cadaadiska ee biraha

Habkani waxa uu la xidhiidhaa bir-gaar ah la taaban karo xoog iyo qaraabo qiime u dhexeeya workpiece iyo qalab. Coolant isticmaalaa in geedi socodka sida waa in hantiyi ku nafwaayay ah oo si weyn u sareeya. Muuqaaladan caan ku darey ah, cadaadis metalworking waa:

• nafwaayay ku filan.
• Resistance si jab iyo kala at xaaladaha heerkulka sare.
• Codso vodnografitovye tonkocheshuychatogo darey la mid noqoshada ee graphite ku salaysan ganaax saliidda.

Features of codsiga ah ee dareeraha jarida

Si loo isticmaalo wax ku ool ah ee coolant waa in ay tixgelisaa a xeerar yar oo sahlan.

• socodka dareeraha Ugu Yar, iyadoo aan loo eegin in ay tahay aqueous ama emulsion - 10-15 l / min.
• Waxaa muhiim ah in socodka coolant waa in goobta waxbarashada lacagta ugu badan ee kulaylka. Marka - waa aag ah oo chips ka workpiece ka soo soocay.
• sahayda ee coolant waa in si deg deg ah in la fuliyo. Marka coolant ka dib markii halka magaabay wiil aad u kulul qaboobi doonaa, taasoo keentay in formation of dildilaaca ku jira.
• Coolant aan codsatay markii jeestay biraha jilic (naxaasta, iyo birta, iwm). Marka qalabka sida sameeyaan chips yar, taas oo laysku daraa iyada oo coolant ah, xidhmin karaa unugyada mashiinka shaqada ee (qaadee caliper, hagaha jir), taas oo keenta in ay xirtaan iyo failure mid ah qaybaha kuwaas oo dhicis ah.

Production iyo kaydinta of jarida dareere

Waxa intaa dheer in kaydinta dheer oo isugu darey dhammaadeen, xoogga, iyo qaybaha soo saaray diyaarinta dareere, dabaqaa xaaladaha of ganacsi oo gaar ah. Coolant, coolant, qiimaha taas oo ku xiran inta badan ka kooban oo u dhiganta nooc gaar ah oo shaqo ee suuqa maanta la xaqiijiyay for 70-160 rubles / litir darey diyaar-dhigay of saarayaasha qoyska iyo 105-290 rubles / litir oo-soo-saarka shisheeye. Qiimaha celcelis ahaan shancosbitaal waa 240 r / litir. Ka hor inta codsanaya dareeraha iyada oo loo marayo habka soo socda:

• Qaboobo waxaa lagu sameeyo qaybaha ku rakibay on Halabuurka iyo stamp heerkulka (60-110 0 C).
• Falanqaynta of Halabuurka si waafaqsan GOST.
• The darey diyaar u kaydsan yihiin weel gaar ah, jidaynayey si ay u fuliyaan kululaynta wareegsan iyo u qaboobo.
• In diyaarinta emulsion ah, hordhaca ah ee lagu daro, oo waxaa lagu fuliyaa on a emulsification vibratory khafiif ah.
• Buuxiyo qalab quudin joogto ah.
• In la isticmaalo walxuhu yihiin wasakhaysan. Bixinta nidaamka nadiifiskeeda u coolant ku harta biraha. waxyaabaha qashinka aan la nadiifin karin, waayo, qubo.
