Jinis sekrup extruder

Ningbo Fangli Technology Co., Ltd. minangka produsen peralatan mekanik kanthi pengalaman meh 30 taunperalatan extrusion pipa plastik, pangayoman lingkungan anyar lan peralatan bahan anyar. Wiwit panyiapan Fangli wis dikembangake adhedhasar panjaluk pangguna. Liwat dandan terus-terusan, R&D independen babagan teknologi inti lan pencernaan & panyerepan teknologi canggih lan liya-liyane, kita wis ngembangakegaris ekstrusi pipa PVC, garis ekstrusi pipa PP-R, Pasokan banyu PE / garis ekstrusi pipa gas, sing disaranake dening Kementerian Konstruksi Cina kanggo ngganti produk impor. Kita wis entuk gelar "Brand kelas kapisan ing Provinsi Zhejiang".

Screw nuduhake rod logam karo alur meneng sing bisa muter ing tong minyak extruder utawa mesin injeksi ngecor. Meneng minangka bagéan paling penting saka extruder kanggo transportasi plastik ngalangi, plastik plasticized lan nyawiji, kang asring disebut jantung extruder. Liwat rotasi sekrup, plastik ing tong minyak bisa mindhah lan entuk tekanan lan gesekan panas. Paramèter geometris saka meneng duwe hubungan gedhe karo karakteristik sakamesin extrusion. Whether the screw design is reasonable or not directly affects the working performance of the mesin extrusion.

A meneng karo kinerja banget ngirim ora mung output dhuwur, nanging uga duwe efek plasticizing sing meets kinerja produk lan kinerja lengkap apik saka suhu, meksa lan kacepetan. Mulane, macem-macem ngawut-awut anyar wis metu siji sawise liyane, kang nemen mbenakake kinerja sakaextruders sekrup tunggal. Sekrup jinis anyar umume dipérang dadi limang kategori: sekrup pemisahan, sekrup penghalang, sekrup jinis shunt, sekrup jinis saluran variabel lan jinis sekrup anyar liyane.

1.Pisahanion meneng

Sekrup pemisahan minangka jinis sekrup sing dirancang miturut prinsip pamisahan fase padhet lan cair ing alur meneng sanalika bisa. sekrup jinis pamisahan khas kalebu BM lanXLK menengs. BM type screw is widely used. It is a double headed screw designed by Maillefer company in Switzerland. The screw structure is to add a secondary screw edge (thread) at the melting section of the screw, which divides the original screw groove into two screw grooves. One spiral groove is connected with the spiral groove of the feeding section (called solid-phase spiral groove), and the other spiral groove is connected with the homogenizing section (called liquid-phase spiral groove). The gap between the secondary screw edge and the barrel is larger than the gap between the main screw edge and the barrel. The melted materials in the solid-phase spiral groove will cross the gap and enter the liquid-phase spiral groove, while the unmelted solid particles will not cross the gap and remain in the solid-phase groove to achieve the effect of solid-liquid phase separation and make the unmelted solid particles melt faster.

Kaluwihan saka separation meneng: efficiency plasticizing dhuwur, kualitas plasticizing apik, meksa nyawiji stabil lan fluktuasi suhu cilik.

2. Skrup penghalang

A "halangan" wis nyiyapake ing bagean tartamtu saka meneng kanggo ngalangi wacana saka phase ngalangi lan ningkataké leleh saka phase ngalangi, kang disebut alangi meneng.

Kaluwihan saka meneng alangi iku mbenakake kualitas plasticizing nyawiji, mbenakake uniformity saka nyawiji plastik, wis efek nyawiji apik lan nyuda prabédan suhu.

3.Bagian campuran saka meneng

Kapasitas nyawiji saka meneng standar (diarani minangka "nyawiji" ing sawetara data) punika relatif kurang. Kanggo nambah kapasitas campuran, akeh desain bagean campuran (bagian campuran) wis muncul.

Ing bagean nyawiji saka meneng bisa dipérang dadi dispersive nyawiji bagean lan mbagekke nyawiji bagean. Bagian pencampuran dispersif kalebu bagean pencampuran Engan, bagean pencampuran UC, bagean pencampuran dray lan bagean pencampuran cincin cembung; Bagian pencampuran sing disebarake kalebu bagean pencampuran jinis pin,Dbagean nyawiji ulmage, Saxton bagean nyawiji, nanas jinis nyawiji bagean, slotted meneng rib, alur transfer nyawiji (CTM), etc.
