Dab tsi yog qee qhov teeb meem tshwm sim thaum lub sij hawm Debugging ntawm lub tshuab tooj liab Granulator tom qab overhaul?

I. Qhov txawv txav Tsis muaj-Load Operation

Cov tsos mob: Pom pom kev vibration, suab nrov txawv txav, lossis kev coj tus kheej overheating thaum tsis muaj- thauj khoom;

Causes: Excessive spindle runout (>0.05mm), misalignment ntawm couplings, xoob thauj tog rau nkoj bolts, los yog tsis tsim nyog bearing installation;

Kev daws: Nres lub tshuab thiab xyuas cov neeg kho tshuab precision. Siv lub dial taw qhia kom ntsuas qhov spindle runout, nruj txhua qhov txuas, thiab rov kho dua yog tias tsim nyog.

II. Key Parameters tsis tuaj yeem calibrated

Symptoms: Large fluctuations in temperature control system (>±5℃), unstable frequency converter speed regulation (speed fluctuation >± 2%), ceev hydraulic siab lwj;

Ua rau: Cov thermocouples puas lossis teeb liab cuam tshuam, tsis raug hloov pauv qhov ntsuas tsis raug, hydraulic valve to, lossis roj Circuit Court thaiv;

Kev daws: Hloov lub sensor faulty, xyuas cov thaiv thaiv thaiv thiab hauv av, rov pib dua qhov hloov pauv zaus, thiab ntxuav lossis hloov cov khoom siv hydraulic.

III. Kev ua haujlwm tsis ruaj khov

Cov tsos mob: Cov kev hloov pauv loj tam sim no thaum lub sijhawm ua haujlwm puv -loading, nquag tswb lub cev muaj zog lossis tsis siv neeg kaw;

Ua rau: Cov ntsia hlau tsis raug- teeb pom kev zoo (<0.2mm or >0.3mm), kev pub mis tsis sib xws, tsis txaus cua txias ua haujlwm;

Cov kev daws teeb meem: Kho qhov kev tshem tawm mus rau cov txheej txheem ntau, ua kom zoo tshaj qhov kev pub mis kom haum rau lub ntsiab chav tsev ceev, thiab xyuas cov dej txias ntws thiab qhov kub thiab txias.

IV. Tsis zoo Granule Forming Quality

Cov tsos mob: Granulation tus nqi<95%, severe granule pulverization, uneven particle size distribution;

Ua rau: Clogged tuag qhov, hnav los yog ntau dhau loj cutter clearance, tsis txaus yaj siab;

Kev daws: Ntxuav lub phaj tuag, tshuaj xyuas thiab hloov lub tshuab txiav, kho lub tshuab hydraulic siab thiab lub sijhawm txias kom paub meej cov khoom siv plasticization txaus.

V. Kev tswj qhov system tsis zoo teb

Cov tsos mob: PLC qhov kev pab cuam freezes, HMI zaub yuam kev, tswb muaj nuj nqi malfunction;

Ua rau: Program poob lossis kev noj nyiaj txiag, sensor teeb liab drift, xoob xaim lossis ya raws;

Cov kev daws teeb meem: Rov qab kho qhov kev pab cuam thaub qab, ntsuas tag nrho cov sensors, xyuas cov plua plav thiab noo noo tiv thaiv ntawm lub txee tswj, thiab nruj nreem tag nrho cov hlua txuas.
