Cov yam ntxwv ntawm Tension Rolls

stretch yob

Txij li thaum lub siab nruj yuav tsum tau nyob rau hauv lub ceev ceev txias, nws yog ib qhov tsim nyog los muab lub nro rau cov menyuam ntaus ntawv nyob rau hauv lub tawm thiab inlet seem ntawm seem no, uas yog tsim nyog los cais qhov nro ntawm no thiab lwm yam seem.

Cov yam ntxwv ntawm qhov nro roller yog raws li nram no:

Table 3.24.16 Cov yam ntxwv ntawm cov menyuam nro

Ib tug menyuam nyob rau hauv txhua txheej ntawm nro rollers (tus thib peb cov menyuam ntawm lub inlet tension rollers thiab thawj cov menyuam ntawm lub qhov hluav taws xob nro cov menyuam) muaj ib tug tuav xauv los tuav lub nro thaum lub tsev nres. Lub kaw lus tuav yog nruab nrog nres nres / ncoo thiab pneumatic actuator.

Roller txheej thiab convex

Lub tshuab hluav taws xob yob yog xa nrog lub siab roughness nto, txhawm rau tswj kom zoo adhesion rau sawb thiab tiv thaiv kev nplua, uas tuaj yeem tsim cov nodules thiab khawb. Lub hom phiaj ntawm kev kub kub txheej: a) txhim kho qhov hnav tsis kam ntawm lub cub tawg ntawm qhov kub thiab txias, txhim kho hardness, Cr25Ni20, Cr28Ni48, nrog lub hardness poob, deg roughness txo, ua rau lub strip plam, qhov nro tsis yooj yim los tsim. ; b) lub hom phiaj thib ob yog tiv thaiv nodules, nodulation yog vim lub strip nto; los yog vim nag lossis daus ntawm sawb hlau nyob rau hauv qhov kub thiab txias.

Txau txoj kev: a), supersonic txau tshuab, ua haujlwm kub<500℃, using materials: Co base alloy, good low temperature wear resistance, oxidation resistance and good corrosion resistance; working temperature <900℃, using material: NiCr alloy, good thermal corrosion resistance and wear resistance under medium and high temperature conditions, corrosion resistance, corrosion resistance, micro vibration and grinding wear, good corrosion resistance, good wear and oxidation resistance at medium and high temperature.

B), Explosion spraying technology, working temperature>900 degree, siv cov ntaub ntawv: alloy ntxiv oxide (hlau ceramics), kub hnav tsis kam, kub oxidation tsis kam, siab kub txuas tsis kam (nodulation kuj).

Lub tswv yim tsim ntawm cov ntaub ntawv kub resistant yog: hlau (hlau alloy) ntxiv rau hlau ceramics (tsis yog hlau). Qhov zoo tshaj plaws kub hardness yog non-metallic ceramics. Txhawm rau kom ntseeg tau tias cov khoom siv hluav taws xob tsis poob, cov hlau theem (kev sib txuas theem) thiab cov hlau ceramics (tsis yog hlau) yuav tsum tau ntxiv los xyuas kom meej lub zog, shedding kuj thiab lub zog, xws li LCO{{3. ib, 56. 1001000 degree kev ntsuas dej txias.

Lub hauv paus ntsiab lus txheej txheem ntawm lub qhov cub kub kub ntawm cov khoom siv hluav taws xob yog qhov zoo ib yam, uas yog, ntu cua sov, ib feem ntawm cov cua sov thiab cua txias seem txais cov txheej txheem kub kub, thiab 950 lossis 1050 degree hauv cov cua sov thiab ib nrab 050. degree tshav kub tiv thaiv txheej. Coated roller roughness yog nruab nrab ntawm 1 thiab 10 μm Ra. Muaj ob peb txheej khoom thiab cov npe thoob ntiaj teb, raws li hauv qab no:

Table 3.24.18 Daim ntawv teev cov cua sov rau cov menyuam cov yam ntxwv thiab cov chaw muag khoom thiab hom

Cov menyuam tsav lub cev muaj zog: Cov kab hluav taws xob sib txuas ntawm cov hlua hlau yog tsav los ntawm lub cev muaj zog thiab iav lub cev muaj zog, thiab suav nrog cov ntaub ntawv hauv qab no: siab tshaj plaws ceev 420 mmHg, acceleration / deceleration rate 10 mp m / sec, braking rate 30 mp m / sec, siab tshaj strip nro 15N / mm², Qhov siab tshaj plaws strip nro qhov sib txawv {{0}}.1 N / mm2 / yob (cua sov / cua sov), 0.3 N / mm2 / yob (txias / qhov hluav taws xob).
