Zvishoma nezvishoma-Type Single Screw

Iyi zvishoma nezvishoma-mhando screw inogadzirwa kubva ku38CrMoAla simbi. Raw material yakakosha pakukora mashandiro, uye tinosarudza simbi yakasimba-yakasimba uye isingapfeki kubva kune vane mukurumbira vekuChina vanogadzira simbi inoenderana nemitemo yenyika (GB/T 3077).

Nanhaiya's tgradual-type single screw extruders yakakamurwa kuita zvikamu zvitatu zvichienderana nebasa razvo. Hudzamu hwenyere muchikamu chega chega hunodzikira zvakatevedzana pasina zvinooneka shanduko dzinongoerekana dzaitika, zvichigadzira yakatsetseka, "zvishoma nezvishoma" chimiro.

Chikamu chekudya chinowanzo verengera 20% -30% yehurefu hweserusa. Iyo yekumanikidza chikamu, chikamu chepakati che screw, inoverengera chikamu chikuru (40% -50%) uye ndiyo musimboti weiyo zvishoma nezvishoma chimiro. Kudzika kwenyere kunotanga pahupamhi hwayo muchikamu chekudya uye zvishoma nezvishoma uye zvakaenzana zvinoderera pamwe nekureba kwekona, zvichiita "compression zone."

Chikamu chehomogenization chinowedzera kusanganisa uye kumisa kunyungudika, kuve nechokwadi chekunyunguduka kweyunifomu uye viscosity. Izvo zvinhu zvinozoendeswa kumusoro wekufa pane yakatsiga dzvinyiriro uye kuyerera mwero, kuve nechokwadi chakaenderana mhando yechigadzirwa chakawedzerwa.

Nanhaiya's zvishoma nezvishoma-mhando imwe screw barrels yakapfuura yakawanda R&D uye kuvandudzwa uye iko zvino yakabatanidzwa mumitsetse yekugadzira yakasiyana-siyana yevagadziri, kuwana mamiriro-e-the-art kuita. Isu tinopa 1-2 gore waranti, zvichienderana neiyo chaiyo yekuwedzera reshiyo. Madhiramu eNanhaiya anoita nitriding process, ane 0.8 ~ 2m gobvu layer yenickel-tungsten alloy spray-welded panzvimbo dzinonyanya kupfeka. Izvi zvinowedzera kuoma kwepamusoro kwebhari ndeye HRC55 ~ 62, inowedzera kupfeka kuramba ne2-3 nguva.

Technical Parameter

Feature uye Application

Nanhaiya's zvishoma nezvishoma-mhando imwe screw extruder inoratidzira nhanho-nhatu chimiro chine kupatsanurwa kwakajeka kunoshanda. Iyo inoenderana maitiro paramita (tembiricha, kumhanya, uye kumashure kumanikidzwa) inogona kugadziridzwa zvine mutsindo, ichiita kuti kushanda kuve nyore pane kune nyanzvi screws.

Easy Temperature Control: Iwo matatu-nhanho tembiricha yekumisikidza inotevera "gradient kuwedzera" musimboti. Chikamu chekudya chine tembiricha yakaderera (inongodiwa kupfavisa zvinhu, zvakadai se50-80 ° C nokuda kwekugadzirisa PE), chikamu chekugadzirisa zvishoma nezvishoma chinowedzera kupisa (kusvika pakunyunguduka, se 160-180 ° C ye PE), uye chikamu chehomogenization chinogadzikana panzvimbo yekunyunguduka (yakadai se180-200 ° C). Kugadziriswa kwekushisa kwenzvimbo kwakaoma hakudiwi.

Linear Correlation pakati peSpeed ​​​​uye Output: Mukati inonzwisisika yekumhanyisa renji (kazhinji 30-150 rpm), inobuda inowedzera inosvika mutsara nescrew kumhanya, ichibvisa kudiwa kwekazhinji backpressure muripo wekugadzirisa. Izvi zvinoita kuti ive yakakodzera kune vanotanga vashandisi uye inofambisa inoenderera uye yakagadzikana yakakura-yakakura kugadzirwa (senge 24-awa inoenderera mberi extrusion yemapombi nemafirimu).

Kudzikira kumashure kumanikidzwa kunodiwa: Iyo screw groove kudzika muchikamu chehomogenization inogara uye haina kudzika, uye chete yakajairwa kumashure kumanikidzwa kwe3-8 bar inodiwa kuti ive nechokwadi chekunyunguduka. Kuwedzeredza kumashure kudzvanywa kuchawedzera screw torque, kuwedzera simba rekushandisa, uye kunyange kukonzera kunyungudika kupisa, uye iyo process parameter "kushivirira" yakakwira.

Iyo inononoka-yemhando imwe screw extruder inokodzera kugadzira PE (polyethylene) mafirimu (akadai sekuputira chikafu, mabhegi ezvitoro ezvitoro, uye mabhegi ekuburitsa asingapindi mvura), PP (polypropylene) tambo tepi, uye PVC (polyvinyl chloride) kupisa kupisa firimu. Inogona zvakare kugadzira mapaipi emvura ePVC, mapaipi emvura ePPR, mapaipi egasi ePE, uye mafaera epurasitiki. Inogona zvakare kugadzira PE epurasitiki mabheseni, PP epurasitiki mabhaketi, PVC cable trunking, uye epurasitiki ekuchengetedza mabhokisi. Inogona zvakare kupeta PE uye PP zvinhu zvakadzokororwa uye kugadzira PE mapaipi akazadzwa anosvika gumi muzana calcium carbonate.

Product Details

Yepamberi tempering, chaiyo machining, uye nitriding maitiro anovimbisa kushanda kwakazara kwezvinhu zvakakosha.

Nzvimbo dzisina njodzi dze screw uye dhiramu dzakasimbiswa ne nickel-tungsten alloy layer, inowana 0.8-2.0mm gobvu layer uye zvakanyanya kunatsiridza kupfeka kuramba.
