Chinhu chakakosha chekusagadzikana kwemhando ye extruder barrel screw zvigadzirwa

Nekuda kwekuita kwayo kwakanaka, iyo extruder barrel screw inoshandiswa zvakanyanya mukati memhepo-conditioning, imba yekufefetera mhepo uye kuvharidzira uye kuvharirwa kwemhando dzakasiyana dzinopisa uye dzinotonhora pombi uye midziyo mukuvaka, indasitiri yemakemikari, simbi, kuvaka ngarava, mishonga, mota uye. mamwe maindasitiri. Icho chizvarwa chitsva chezvigadzirwa zvepamusoro-soro. Quality insulation zvigadzirwa. Nekudaro, mhando yechigadzirwa inogona kunge ichiri isina kukodzera nekuda kwezvikonzero zvakasiyana, senge kubvumidzwa kwakanyanya, kupisa tembiricha kutonga, kusagadzikana kushanda kumhanya, nezvimwe.

 

Iko kukanganiswa kwekuwandisa kwakakodzera kubvumidzwa pakati pe extruder barrel uye screw pamhando yechigadzirwa.

1. Kana mukaha pakati pebhari uye screw ye extruder yakakura kwazvo uye kuyerera kwe extruded melt isina kugadzikana, makwinya akatwasuka anozoonekwa zviri nyore pamusoro pechigadzirwa.

2. Kana gaka racho rakanyanya kukura, iyo extrusion melt pressure ichave isina kugadzikana, zvichiita kuti kuchinja kukuru kwechimiro chejometri uye zvikanganiso zvehukuru zvechigadzirwa chemuchinjikwa-chikamu.

3. Kana gap rakakurisa, chiitiko chekudzokera shure chinokonzerwa nechinhu chakanyunguduka chinoenda kumberi mudhiramu chinowedzera, zvichiita kuti zvinhu zvakanyunguduka zvirambe zviri mubhodhoro kwenguva yakareba uye zvikaita yero, izvo zvinokonzera kushanduka kwemavara kana kupisa mavara pa pamusoro pechigadzirwa.

4. Mhepo pakati pebhari uye screw ye extruder yakakura kwazvo, iyo inoita kuti kubuda kwezvigadzirwa zve extruded kusagadzikana kana kuderedzwa.

 

Mhedzisiro yekusagadzikana yekudziya tembiricha kutonga kweiyo extruder barrel screw pamhando yechigadzirwa:

1. Iyo yekudziya tembiricha kutonga haina kugadzikana, zvichikonzera kusaenzana kweplasticization yemhando yezvigadzirwa mudhiramu, zvichikonzera kushata kwepamusoro pechigadzirwa uye kazhinji mvura mamakisi.

2. Kukura kwechikamu chechigadzirwa hachina kugadzikana, uye kukanganisa kwekukura kwejometri kunoshanduka zvikuru.

3. Mapundu akaoma anowanzoonekwa pamusoro pechigadzirwa.

4. Unhu hwechigadzirwa hahuna kugadzikana, simba racho rakashata, uye zviri nyore kuva brittle panguva yekushandiswa.

 

Mhedzisiro yekusagadzikana kushanda kumhanya kweiyo extruder barrel screw pamhando yezvigadzirwa zvepurasitiki:

1. Iyo longitudinal geometric chimiro chechigadzirwa chine zvikanganiso zvakakura zvedimensional.

2. Lateral wrinkles inowanzoonekwa pane zvigadzirwa.

3. Pamusoro pechigadzirwa chacho chakashata, nyore nyore brittle kana ine mazamu akaoma emunharaunda.

 

Izvi zvinotevera zvinokanganisa kumhanya kwekushanda kweiyo extruder barrel screw:

1. Bhandi rekutumira V-shaped rakapfekwa zvakanyanya uye basa riri kutsvedza.

2. Nharaunda yepakati yeV-shaped belt drive pulley iduku zvikuru, kuitira kuti bhanhire rinofambisa mhepo haigoni kushanda zvakanaka ne trapezoidal slope ye pulley.

3. Kupisa kwezvinhu zvinopisa mubhodhoro kwakaderera uye plasticization yezvinhu zvakasvibirira hazvina kuenzana, izvo zvinoita kuti screw rotation ishande mutoro torque kuwedzera uye screw speed kuva isina kugadzikana.

4. The thrust shaft ye screw yakakuvadzwa, nezvimwe.
