Summary: Shaashada leyska leh ee wareega ah waxaa ka kooban tahay sanduuqa shaashada, kiciyaha, qalabka taageerada iyo qaybaha kale....
Shaashadda goynaysa ee wareegta ah waxaa ka kooban sanduuqa shaashadda, kiciyaha, qalabka taageerada iyo qaybaha kale.
Sanduuqa shaashadda wuxuu ka kooban yahay rariin shaashad, dusha shaashadda iyo qalabka xoojinta. Kiciyaha gariirka waxaa ka kooban laba mooto gariir ah oo ku yaal laba dhinac oo ku xiran isku xidhka guud ee dhexda. Sanduuqa shaashadda waxaa taageera 8 xuubo.
Qiyaasta gariirka ee ka dhalata isha gariirka ee shaashadda goynaysa ee wareegta ah waa xoog inertial ah oo is beddelaya jihada togan agagaarka halkii xiddig, oo asal ahaan ay tahay centrifu.
Mabda' shaqada shaashada gariirka wareegsan waa in markii shaashada gariirku bilaabatay, qalabka gariirka shaashadu wuxuu ku keenaa sanduuqa shaashada dhaqdhaqaaq boodbood ah oo isku jiho ah, inta lagu jiro taas, walxaha ka yar godka dusha shaashada ayaa hoos u dhacayaa lakabka hoose iyada oo maraysa godadka shaashada, taasina waxay noqonaysaa walxaha hoos maray shaashada, walxaha ka wayn dusha shaashada ayaa laga soo saaraa godka soo saarista kadib dhaqdhaqaaq joogto ah oo boodbood ah, ugu dambeyntiina shaqada kala soociddu waa dhammaystirtay.
Xulashada Qiyaasaha Shaashadda Wareega ee Vibrating
(1) Tuuritaanka Tilmaanta
Guud ahaan, iyadoo lagu saleynayo isticmaalka shaashadda, shaashadda wareega ee gariirka leh guud ahaan waxay qaadanaysaa KV=3～5, halka shaashadda gariirka toosan ay qaadanayso KV=2.5～4. Maaddada adag in la kala saaro waxay qaadanaysaa qiimo weyn, halka maaddada fudud in la kala saaro ay qaadanayso qiimo yar. Marka godadka shaashadda ay yaryihiin, waxaa la qaadanayaa qiimo weyn, marka godadka shaashadda ay wayn yihiin, waxaa la qaadanayaa qiimo yar.
(2) Xoogga Gariirka
Doorashada xoogga gariirka K guud ahaan waxaa xadidaya xoogga qalabka iyo adkaanta qaybihiisa. Heerka farsamada ee hadda ee K guud ahaan waa dhexdeeda 3 ilaa 8, xaaladda shaandhada gariirku guud ahaan waa dhexdeeda 3 ilaa 6.
(3) Aragtida geeska dusha shaashadda
For circular vibrating screen, the inclination angle of the screen surface generally takes 15°~25°, takes the small value when the amplitude is large, and takes the large value when the amplitude is small.
(4) Dhererka sanduuqa shaashadda
Awooda shaashadda sanduuqa A waa qiyaas muhiim ah oo loogu talagalay naqshadeynta shaashadda gariiraysa, qiimaheeduna waa inuu ku habboon yahay si loo xaqiijiyo kala-sooc fiican oo agabka ah, loo yareeyo xannibaadda, loona fududeeyo habka shaashadda. Caadi ahaan A=3∼6 mm; meelaha godadka weelka ayaa ah mid weyn, qiimaha la aasaaso ayaa ah mid weyn, iyo meelaha godadka yaryar, qiimaha la aasaaso ayaa ah mid yar.
Talooyin lagu dooranayo shaandhada gariirada wareegsan
Arrimaha ugu muhiimsan ee la tixgeliyo marka la dooranayo noocyada mashiinka shaandhaynta waa:
- Sifooyinka walxaha shaandhaynta (qadarkeeda buuraha ku jira, qadarkeeda qaybaha adag ee shaandhaynta, qoyaanka iyo qoyaanka ku jira walxaha, qaabka walxaha, miisaanka gaarka ah ee walxaha, iwm.);
- Qaab-dhismeedka mashiinka shaandhada (aagga shaandhada, tirada lakababka shaandhada, cabbirka iyo qaabka daloolada shaandhada, saamiga aagga daloolada shaandhada, habka dhaqdhaqaaqa mashiinka shaandhada, iyo ballaca iyo tirada gariirka, iwm);
- Shuruudaha farsamada habaynta faa'iidada (kaabayaasha habaynta, waxtarka shaandhaynta, habka shaandhaynta, xagasha incline ee mashiinka shaandhaynta), iwm.
Marka laga reebo in la tixgeliyo arrimaha kor ku xusan, mabaadi'da aasaasiga ah ee soo socda waa in la ixtiraamaa:
(1) Kadib marka la go'aamiyo aagga shaandhaynta, ballaca dusha shaandhaynta waa inuu ugu yaraan noqdaa 2.5 ilaa 3 jeer cabirka xajmiga ugu weyn ee walxaha si looga hortago in shaandhada ay xidhanto walxo waaweyn.
(2) Si shaandhada gariirku u shaqeyso si fiican, boqolkiiba dhererka iyo ballaca shaandhada waa in la xusho iyadoo dhexdeeda ah 2 ilaa 3.
(3) Waxyaabaha shaashadda lagu sameeyo iyo qaabkeeda ku habboon xaaladaha shaqada waa in la doortaa.
(4) Go'aaminta cabbirka shabagga
Marka la isticmaalayo shaandho fiican, shaandho arc, shaandho gariir toosan si loo shaandheeyo qaybaha waxyaabaha yar-yar, cabbirka fagaare ee shaandhada waa 2 ilaa 2.2 jeer cabbirka qaybaha kala soocida, ugu badnaanna ma dhaafi doonto 3 jeer;
Shaashadda gariirka ah ee loo isticmaalo shaandhaynta walxaha dhexdhexaadka ah, cabbirka shabakadda shaashadda waa 1.2 jeer cabbirka qaybta kala soocida;
Marka loo isticmaalo in lagu shaandheeyo alaabada qoyan ee dhumuc weyn leh, cabirka shaandhada waa inuu noqdaa 1.05 jeer cabbirka qaybta go'doominta;
Shaashadda shaqada aragtida suurtogalnimada, cabbirka shaashadda guud ahaan waa laba ilaa laba iyo bar jeer cabbirka dhabta ah ee qaybaha qaybsan.
(5) Go'aami haddii aad dooranayso shaashad laba-laab ama dhowr-laab
Marka kala duwanaanshaha cabbirka qaybaha la kala soocayo ee maaddada la kala soocayo uu ballaaran yahay, shaashad laba-laab ah waxaa loo isticmaali karaa shaashad keliya, taasoo hagaajinaysa awoodda farsamada kala soocidda, ilaalisa shaashadda hoose, iyo kordhinaysa nolosha adeegga shaashadda hoose. Doorashada cabbirka shaashadda ee shaashadda gariirka laba-laabka sare waxaa guud ahaan go'aaminaya cabbirka qaybaha
(6) Go'aami aagga hawlgalka ee hufan ee shaashadda
Aagga shaandhaynta ee lagu xisaabiyay iyadoo loo eegayo shuruudaha habka wax soo saarka waa aagga hufan ee shaashadda, iyo qeexitaanka shaashadda waa aagga dhammeystiran ee shaashadda.
Shaashadda gariiraysa ee loo isticmaalo shaandhaynta alaabaha cabir dhexe, aagga shaandhaynta hufan waa in uu noqdaa 0.8 ilaa 0.85 jeer aagga dhammeystiran ee shaashadda. Dabcan, tani waxay si dhow ula xidhiidhsan tahay heerka furitaanka shaashadda ee dusha shaashadda.
(7) Alaabada ka badan 200mm, shaashadaha gariiraya ee culus ayaa inta badan la isticmaalaa; alaabada ka sarreeya
(8) Marka xaaladaha qofka oggol yahay, shaashad joogto ah ayaa la doorbidi karaa si loo fududeeyo kormeerka iyo dayactirka. Marka shaashad la tuuro lagu qasbo in la doorto, dhererka tuurista waa in la yaray si loo yareeyo dhex-dhexaadinta garaaca shaashadda gariiraysa loona fududeeyo hawlgallada wax-soo-saarka.
Marka la dooranayo qalabka shaashadda, ma aha in la tixgeliyo kaliya sabab keliya, laakiin waa in si dhameystiran loo tixgeliyaa arrimo kala duwan si loo hubiyo in la dooranayo qalabka ku haboon xaaladaha shaqada.
