Kusankha magawo ogwirira ntchito a decanter centrifuge

Wogwiritsa ntchito akhoza kusankha moyenera magawo ogwirira ntchito a centrifuge malinga ndi mawonekedwe enieni a chinthu cholekanitsidwa (kuimitsa), zofunikira pakulekanitsa, mphamvu yogwirira ntchito, zofunikira pakukonza ndi zina, kuti zotsatira zokhutiritsa pakulekanitsa ndi phindu lazachuma zipezeke.

1. Makhalidwe a zipangizo zoyimitsira

a, tinthu tolimba tikakhala tating'onoting'ono kwambiri m'zinthuzo, zimakhala zosavuta kulekanitsa, kukula kwa tinthu tolimba sikufanana, gawo laling'ono la tinthu tolimba limatsimikiza zotsatira zake zomaliza zolekanitsa, makina nthawi zambiri amatha kuchotsa tinthu tolimba toposa 5um, tinthu tolimba timakhala ndi maola abwino kwambiri, ndiko kuti, sitidzalekanitsidwa, ndipo ndi kutulutsa madzi komveka bwino; Zotsatira zomaliza zolekanitsa zimadalira kufalikira kwa tinthu tolimba m'zinthuzo, tinthu tochuluka tikakhala pamwamba pa 5um, zotsatira zolekanitsa zimakhala zabwino; M'malo mwake, zotsatira zolekanitsa zimakhala zoyipa kwambiri.

b, nthawi zambiri crystalline solid ndi fibrous solid zimakhala zosavuta kulekanitsa, flocculent, phala lolimba ndi lovuta kulekanitsa, chifukwa madzi ambiri osungunuka a flocculent paste solid phase ndi akulu, spiral push sludge, yosavuta kutsetsereka ndikukhudza zotsatira za kulekanitsa, kotero kuchuluka kwa madzi sikuyenera kukhala kwakukulu kwambiri polekanitsa flocculent ndi phala lolimba.

c, kusiyana kwakukulu kwa kulemera pakati pa gawo lolimba ndi gawo lamadzimadzi, kulekanitsa kumakhala bwino, ndipo zotsatira zake zimakhala zoyipa kwambiri.

d, kukhuthala kwa gawo lamadzimadzi kukakhala kochepa, kumakhala kosavuta kulekanitsa, kukhuthala kwa gawo lamadzimadzi kumakhala kwakukulu, gawo lolimba kwambiri mumadzimadzi oyeretsedwa, kukhuthala kwa kulekanitsa kumakhala koipa, ndiye kuti kutentha kwa zinthu kumatha kuwonjezeka, kuchepetsa kukhuthala kuti kukhale bwino pakulekanitsa (kutentha kwakukulu kwa chakudya sikoposa 95℃).

2, kusankha kayendedwe ka chakudya (ndiko kuti, mphamvu yogwiritsira ntchito)

Malinga ndi mfundo yolekanitsa, kuchuluka kwa chakudya komwe kumachepa, kuchuluka kwa axial flow ya zinthu zomwe zili mu ng'oma kumachepa, nthawi yayitali yokhalamo ya zinthu zomwe zili mu ng'oma, kumakhala bwino kusiyana. Pamene kuchuluka kwa chakudya kukuwonjezeka, kuchuluka kwa axial flow kumawonjezeka, nthawi yosungira zinthu zomwe zili mu ng'oma imachepa, kusiyana kumawonjezeka, kuchuluka kwa chakudya cha centrifuge kumachepetsedwanso ndi mphamvu yayikulu yotulutsa slag ya spiral, kuchuluka kwa chakudya kumakhala kwakukulu kwambiri, matope olekanitsidwa sadzatulutsidwa pakapita nthawi ndipo amachititsa kuti ng'omayo itseke, choncho iyenera kugwiritsidwa ntchito malinga ndi mawonekedwe a zinthuzo, zofunikira zolekanitsa ndi zomwe zili zolimba pa zinthuzo. Sankhani kuyenda koyenera kwa chakudya, zomwe zili zolimba nthawi zonse zimakhala zazikulu pamene kuchuluka kwa chakudya sikuyenera kukhala kwakukulu kwambiri, zitha kuyerekezedwa ndi zotsatira zolekanitsa za kuyenda kosiyanasiyana kuti mudziwe kuyenda koyenera kwa chakudya, nthawi zambiri kuti zikhale zovuta kulekanitsa kuyenda koyenera sikuyenera kukhala kwakukulu kwambiri, kosavuta kulekanitsa kuyenda kwa zinthuzo kungakhale kwakukulu, koma samalani kuchuluka kwakukulu kwa slag flow spiral, apo ayi zingayambitse kutsekeka.

3. Kuchuluka kwa madzi m'mimba mwake

Ngati m'mimba mwake mwa dramu muli wochepa, malo okhazikika ndi aatali, malo ouma ndi afupiafupi, madzi a m'matope olimba ndi ochuluka, madzi oyeretsedwa ndi omveka bwino, ndipo kusiyana kumakhala bwino. M'malo mwake, m'mimba mwake mwa dramu muli waukulu, m'matopewo ndi ouma kwambiri, ndipo kusiyana kumakhala koipa kwambiri. Pakugwiritsa ntchito kwenikweni, m'mimba mwake mwa dramu muyenera kusankhidwa moyenera malinga ndi zofunikira za chinyezi cha m'matope olimba pambuyo pa kuyesa kwa ntchito. Kukula kwa m'mimba mwake mwa dramu kumatha kusinthidwa posintha chivundikiro chachikulu cha m'mapeto a dramu, ndipo chivundikirocho chikhoza kuchotsedwa m'mimba mwake waukulu.

4, liwiro la ng'oma:

Liwiro la ng'oma likakwera kwambiri, chinthu cholekanitsa chimakula kwambiri, nthawi zambiri chimakhala bwino kwambiri, koma kugwedezeka ndi phokoso la centrifuge zimawonjezekanso, moyo wa bearing udzachepa, kusankha liwiro lalikulu kwambiri sikotsika mtengo, nthawi zambiri chifukwa chokwaniritsa zofunikira za njira yolekanitsa, liwiro loyenera limasankhidwa ngati liwiro logwira ntchito.

5, kusiyana kwa liwiro la screw ndi ng'oma

Liwiro la kusiyana kwakukulu, mphamvu yotulutsa slag ya spiral imakula, koma chinyezi cha sediment chikachuluka, kusokonezeka kwa spiral kuzinthuzo kumakula, ndipo kusiyana kumakhala koipa kwambiri, koma pazinthu zomwe zimalekanitsidwa mosavuta, liwiro lingagwiritsidwe ntchito kukweza mphamvu yotulutsa slag ya spiral kuti iwonjezere mphamvu yokonza, koma chinyezi cha sediment chidzawonjezeka. Chifukwa chake, kukula kwa liwiro la kusiyana kuyenera kutsimikiziridwa ndi mayeso olekanitsa zinthu ndi zofunikira pa njira.
