Gradual-Type Ib Screw

Qhov no maj mam-hom ib leeg ntsia hlau yog tsim los ntawm 38CrMoAla steel. Cov khoom siv raw yog qhov tseem ceeb rau kev ua haujlwm ntawm cov ntsia hlau, thiab peb xaiv cov hlau uas muaj zog thiab hnav-resistant los ntawm cov neeg tsim khoom nrov hauv Suav teb uas ua tau raws li cov qauv hauv tebchaws (GB / T 3077).

Nanhaiya's tgradual-hom ib leeg ntsia hlau extruders tau muab faib ua peb ntu raws li lawv txoj haujlwm. Qhov tob ntawm cov flutes nyob rau hauv txhua ntu txo qis zuj zus yam tsis muaj kev hloov pauv sai sai, tsim kom muaj tus qauv zoo, "qhib".

Cov khoom noj feem ntau suav rau 20% -30% ntawm tag nrho cov ntsia hlau ntev. Cov seem compression, ntu nruab nrab ntawm cov ntsia hlau, tso nyiaj rau qhov loj tshaj plaws (40% -50%) thiab yog qhov tseem ceeb ntawm cov qauv gradual. Lub flute qhov tob pib ntawm nws qhov siab tshaj plaws nyob rau hauv seem pub thiab maj mam thiab sib npaug ntawm qhov ntev ntawm cov ntsia hlau, tsim ib qho "compression zone."

Cov seem homogenization ntxiv sib tov thiab agitates lub yaj, kom ntseeg tau tias qhov kub thiab txias thiab viscosity. Cov khoom yog tom qab ntawd xa mus rau lub taub hau tuag ntawm lub siab ruaj khov thiab ntws tus nqi, kom ntseeg tau zoo ib yam ntawm cov khoom extruded.

Nanhaiya cov gradual-hom ib leeg ntsia hlau chim tau dhau los ua ntau R & D thiab kev txhim kho thiab tam sim no tau koom ua ke rau hauv ntau cov tuam txhab tsim cov kab ntau lawm, ua tiav qhov kev ua tau zoo ntawm lub xeev. Peb muab 1-2 xyoo warranty, nyob ntawm seb cov khoom siv tshwj xeeb ntxiv piv. Nanhaiya cov thoob tau txais cov txheej txheem nitriding, nrog 0.8 ~ 2m tuab txheej ntawm nickel-tungsten alloy txau-welded rau ntawm qhov chaw hnav khaub ncaws feem ntau. Qhov no ua rau kom qhov tawv tawv ntawm lub thoob yog HRC55 ~ 62, txhawb kev hnav tsis kam los ntawm 2-3 zaug.

Technical Parameter

Feature thiab Application

Nanhaiya's gradual-hom ib leeg ntsia hlau extruder nta peb-theem qauv nrog kom meej meej kev faib ua haujlwm. Cov txheej txheem tsis sib xws (kub, ceev, thiab rov qab siab) tuaj yeem hloov kho qhov tseeb, ua haujlwm yooj yim dua nrog cov ntsia hlau tshwj xeeb.

Kev Tswj Kub Yooj Yim: Qhov ntsuas kub peb-theem ua raws li "gradient nce" hauv paus ntsiab lus. Cov khoom noj muaj qhov kub qis tshaj plaws (tsuas yog yuav tsum tau ua kom cov khoom muag muag, xws li 50-80 ° C rau PE ua), ntu compression maj mam nce hauv qhov kub thiab txias (kom ncav cuag qhov melting point, xws li 160-180 ° C rau PE), thiab seem homogenization stabilizes ntawm melting point (xws li 180-200 ° C). Tsis tas yuav hloov qhov kub thiab txias hauv zos.

Linear Correlation ntawm Ceev thiab tso zis: Nyob rau hauv ib tug tsim nyog ceev ntau yam (feem ntau 30-150 rpm), cov zis nce kwv yees li linearly nrog cov ntsia hlau ceev, tshem tawm qhov yuav tsum tau rau nquag backpressure them nyiaj kho mob. Qhov no ua rau nws haum rau cov neeg ua haujlwm tshiab thiab pab txhawb kev tsim khoom loj thiab ruaj khov (xws li 24-teev txuas ntxiv ntawm cov kav dej thiab cov yeeb yaj kiab).

Tsawg rov qab siab yuav tsum tau: Cov ntsia hlau zawj qhov tob nyob rau hauv homogenization seem yog tas li thiab ntiav, thiab tsuas yog ib tug pa rov qab siab ntawm 3-8 bar yog yuav tsum tau los xyuas kom meej yaj uniformity. Lub siab rov qab ntau dhau yuav ua rau cov ntsia hlau torque, nce lub zog noj, thiab txawm tias ua rau yaj overheating, thiab cov txheej txheem parameter "tolerance" siab.

Cov txheej txheem ib zaug ib leeg ntsia hlau extruder yog tsim los tsim PE (polyethylene) cov yeeb yaj kiab (xws li cov ntaub qhwv zaub mov, hnab khw hauv khw, thiab cov hnab ntim dej tsis muaj dej), PP (polypropylene) strapping daim kab xev, thiab PVC (polyvinyl chloride) tshav kub ntsws zaj duab xis. Nws tseem tuaj yeem tsim cov kav dej PVC, PPR cov kav dej, cov kav dej PE, thiab cov yas qhov rais thav duab. Nws tseem tuaj yeem tsim PE yas phiab, PP yas thoob, PVC cable trunking, thiab cov thawv ntim yas. Nws tseem tuaj yeem pelletize PE thiab PP cov ntaub ntawv siv dua tshiab thiab tsim cov kav dej PE uas muaj txog li 10% calcium carbonate.

Khoom Paub meej

Advanced tempering, precision machining, thiab nitriding txheej txheem xyuas kom meej qhov kev ua tau zoo ntawm cov khoom tseem ceeb.

Cov chaw tsis muaj zog ntawm cov ntsia hlau thiab lub thoob tau ntxiv dag zog nrog cov nickel-tungsten alloy txheej, ua tiav 0.8-2.0mm tuab txheej thiab txhim kho kev hnav tsis kam.
