Kuongorora Uye Kugadziriswa Kwezvakajairika Kukundikana KwePurasitiki Extruder

Iyo extruder chinhu chakakosha chemidziyo yepurasitiki yekuumba kugadzira uye pelletizing. Iko kushandiswa kwemazuva ese kweextruder kunogona kupa kutamba kwakazara kune kunyatsoshanda kwemuchina uye kuchengetedza yakanakisa kushanda mamiriro. Inofanira kunyatsochengeta zvisingaregi kuwedzera hupenyu hwebasa remudziyo. Kutadza kweiyo extruder kwekutanga ruzha rusina kujairika uye kuzunguzika kunokonzerwa nekupfeka zvisina kujairika, kupfeka kana kukuvadzwa kwezvikamu zvekutapurirana, uye mafuta asina kukwana.

Zvakajairika kukanganisa kwepurasitiki extruder:
1. Ikozvino yekutambira haina kugadzikana
Zvikonzero zvekugadzira:
● Kudyisa zvisina kuenzana.
● Iyo huru inotakura mota yakakuvadzwa kana kuti isina mafuta.
● Chikamu chakananga chemoto chinokundikana uye hachipisi.
● The screw adjustment pad yakashata, kana kuti chikamu chinotyisa, uye zvikamu zvinopindira.

Nzira:
● Tarisa pa feed uye kugadzirisa dambudziko.
● Hwirudzura injini huru uye wotsiva mabhengi kana zvichidiwa.
● Tarisa uone kana hita imwe neimwe ichiwanzoshanda, uye chinja hita kana zvichidiwa.
● Tarisa padhi yekugadzirisa uye dhonza screw kuti uone kana pane kupindira mu screw.

2. Motokari huru haigoni kutanga
Cause:
● Pane kukanganisa munzira yekutyaira.
● Pane dambudziko netambo huru yemota, ingave fuse inotsva.
● Chishandiso chekubatanidza chine chekuita nemota yekutanga inoshanda
Nzira:
● Tarisa maitirwo acho wotyaira zvakare munhevedzano yekutyaira.
● Tarisa yekutanga injini yedunhu.
● Tarisa kana pombi yeoiri yekuzora yatangwa uye tarisa mamiriro emudziyo wakavharika une chekuita nemota huru. Pombi yemafuta haigone kubatika, uye injini haigone kubatika.
● The induction current ye inverter haina kusunungurwa. Bvisa simba guru uye umirire kwemaminitsi mashanu usati watanga.
● Tarisa uone kana bhatani re emergency ragadziridzwa patsva.

3.Musoro wemashini hausi wakatsetseka kana wakavharwa
Cause:
● Chimwe chikamu chehita hachishande, uye purasitiki yemidziyo haina kunaka.
● Tembiricha yekushanda yakadzikira zvakanyanya, kana kugovanisa kwepurasitiki kwema molecular weight yakakura uye haina kugadzikana.
● Panogona kunge paine zvimwe zvinhu zvisiri nyore kunyungudika.
Nzira:
● Tarisa hita woitsiva kana zvakakodzera.
● Ongorora tembiricha yakatarwa yechikamu chimwe nechimwe, taurirana nenyanzvi kana zvichidiwa, uye wedzera kukosha kweseti yekushisa.
● Chenesa uye tarisa extrusion system uye musoro wemashini.

4. Yekutanga yekutanga ikozvino yakanyanya kukwirira
Cause:
● Nguva yekupisa haina kukwana, uye torque yakakwana.
● Chikamu chaicho chehita hachishandi.
Nzira:
● Usati watyaira, shandisa vhiri remaoko. Kana zvisiri nyore, wedzera nguva yekudziya kana kutarisa kana chikamu chimwe nechimwe chehita chinoshanda zuva nezuva.

5. Iyo injini huru inoita ruzha rusina kujairika
Cause:
● Iyo huru inotakura mota yakakuvadzwa.
● Imwe SCR mu SCR rectifier circuit ye ​​primary motor yakakuvadzwa.
Nzira:
● Tsiva huru inotakura injini.
● Tarisa thyristor rectifier circuit, uye shandura chinhu chinonzi thyristor kana zvichidiwa.

6.Iyo huru mota inotakura tembiricha inokwira yakanyanya
Cause:
● Kusashanda zvakanaka kwemafuta.
● Kutakura kwakasakara.
Nzira:
● Tarisa uye wedzera mafuta. Tarisa mabhengi emota uye woatsiva kana zvichidikanwa.

7.Musoro wemusoro ndiwo usina kugadzikana
Cause:
● Kutenderera kumhanyisa kwemota yekutanga haina kuenzana.
● Kukurumidza kwemotokari yekudya kunoshanduka, uye chiyero chekudya chinoshanduka.
Nzira:
● Chengetedza gadziriro yemotokari yepakati uye mabhengi.
● Tarisa hurongwa hwekudyisa motokari uye hurongwa hwekutonga.

8. Low lubricating mafuta pressure
Cause:
● Ukoshi hwekuisa vheruvhu yeoiri yekuzora pressure inodzora vharafu yakadzikira.
● Pombi yeoiri yakashata, kana kuti pombi yokusveta oiri yakavharika.
Nzira:
● Tarisa uye gadzirisa vharuvhu yekudzora kudzvinyirira kwemafuta ekuzora.
● Tarisa pombi yemafuta nepombi yekukweva.

Kuti udzivise kukundikana uye kugadzirisa kwezuva nezuva, kugadzirisa, uye kugadzirisa zvakanyatsoenderana nezvinodiwa, zvakare zvinodiwa kutarisisa kupfekedzwa kweiyo extruder screw.
Iyo yakajairika kupfeka screw uye mbiya yepurasitiki extruder inowanzoitika munzvimbo yekudyisa uye nzvimbo yekuyera. Chikonzero chikuru chekupfeka ndiko kukakavara kwakaoma pakati pe chip particles uye pamusoro pesimbi; kana chip ichipisa uye ichinyorova, inoderera.

single screw extruder

Kupfeka zvisina kujairika kwesiruu uye mbiya kuchaitika kana screw lock nemapfundo emhete uye zvinhu zvekunze. Ring knot zvinoreva kuti chinhu chakakonyedzwa chinokiya sikururu. Kana iyo screw extruder ikashaya mudziyo wekudzivirira wakakodzera, simba rekutyaira rine simba rinogona kumonyoroka. Kana sikururu yakanamira, inoburitsa kuramba kwakakura, zvichikonzera kukuvara kwakanyanya pamusoro pescrew uye makwara akanyanya padhiramu.
Mavanga ari padhiramu anonetsa kugadzirisa. Iyo dhiramu yakagadzirirwa musimboti kuona kuti hupenyu hwesevhisi hwakareba kupfuura iyo screw. Pakupfeka kwedhiramu zvakajairika, kazhinji haigadziriswe. Iyo nzira yekuvandudza screw thread inowanzo shandiswa kudzoreredza gap reradial pakati pegomba remukati megomba uye dhayamita rekunze re screw.

Solution:
Kukuvadzwa kwepanzvimbo kwescrew thread kugadziridzwa nekuisa welding yeakakosha anti-kupfeka uye inodzivirira corrosion alloy. Kazhinji, inert gasi yakadzivirirwa welding, uye plasma argon iri welding, uye simbi yekupfapfaidza tekinoroji inogona kushandiswawo kugadzirisa. Chekutanga, geya chekunze chesiruu yakasakara kusvika pakadzika inosvika 1.5mm, wofukidza alloy layer kusvika saizi yakakwana kuti uve nechokwadi chekubvumidza machining, uye pakupedzisira geya denderedzwa rekunze resiruru nedivi rescuru kusvika saizi yepakutanga yescrew size.

Ruzha rwakaipa
● Kana ikaitika muchinakisisa, inogona kukonzerwa nekutakura kukuvara kana kusakwana kwemafuta kana kukonzerwa nekupfeka kwegiya, kuiswa zvisina kufanira, uye kugadzirisa, kana meshing isina kunaka. Inogona kugadzirisa nekutsiva mabhengi, kuvandudza lubrication, kutsiva magiya, kana kugadzirisa giya meshing mamiriro.
● Kana ruzha rwuri ruzha rwakapinza, funga nezve mukana weiyo shaft musoro uye dhiraivha shaft sleeve kukwesha nekuda kwekutsauka kwedhiramu. Inogona kugadzirisa nekugadzirisa dhiramu.
● Kana dhiramu rikaita ruzha, zvinogona kunge zviri nekuti sikuruu yakakotama kutsvaira chibhorani kana kuti tembiricha yakadzikira, zvichikonzera kukweshana kwakanyanya kwezvimedu zvakasimba. Inogona kugadziriswa nekugadzirisa screw kana kuwedzera tembiricha yakatarwa.

Abnormal vibration
Kana izvi zvikaitika pazvinoderedza, zvinokonzerwa nekupfeka kwemabheya uye magiya, ayo anogona kugadziriswa nekutsiva mabheya kana magiya. Kana zvikaitika pabhodhoro, imhaka yechinhu chakaoma chekunze chakasanganiswa muzvinyorwa, uye kuchena kwezvinhu zvinoda kuongororwa. Kana zvichidikanwa, isa yakasimba magineti mudziyo mune hopper kuti adsorb iron filings.

Annular blockage pane screw inlet
Kutadza uku kunonyanya kukonzeresa nekuvhiringwa kwemvura inotonhodza kana kuyerera kusina kukwana. Iyo yekutonhodza sisitimu inoda kutarisa, uye kuyerera uye kudzvanywa kwemvura inotonhorera kunofanirwa kugadzirisa kune zvakatemwa zvinodiwa. Zvingave zvakare kuti chimedu chihombe chemidziyo yakadzokororwa mune yakasvibirira inovhara iyo inopinza uye inoda kuchenesa. Inlet.
Iri pamusoro ndiyo yakajairika kukundikana kuongororwa uye epurasitiki extruder mhinduro. Ona kuti wakazvidzidza here?
