Feem ntau, tom qab 2 xyoos ntawmOverlock Tshuab xawskev ua haujlwm, kev saib xyuas ntau dua yuav tsum tau ua. Qhov thib ob-chav saib xyuas ntawm lub tshuab xaws yog muab faib ua disassembly, tu, overhaul, assembling, thiab commissioning.
1) Disassembly
Lub disassembly ntawm luboverlock tshuab xawsyuav tsum ua raws li lub hauv paus ntsiab lus ntawm sab nraud mus rau sab hauv. Feem ntau, lub disassembly tuaj yeem ua tau raws li cov kauj ruam hauv qab no:
Foot pressing mechanism Pub mechanism Koob dabtsi yog khoov mechanism Lower cutter los ua ke koob pas nrig threading los ua ke Tsav los ua ke Upper cuab yeej nqa los ua ke Roj twj tso kua mis los ua ke Main ncej Pin puag hloov mechanism.
Nws yuav tsum raug sau tseg tias cov cuab yeej sib txawv tuaj yeem raug tshem tawm hauv cov kauj ruam sib txawv thiab raws li cov qauv tshwj xeeb.
Ua ntej disassembly, nws yog ib qho tseem ceeb los txiav txim siab txog kev sib raug zoo thiab kev txheeb ze ntawm cov koom haum, cov khoom, thiab cov khoom. Thaum lub sij hawm disassembly, lub Cheebtsam yog npaj raws li lawv cov kev faib ua feem kom tsis txhob muaj teeb meem installation thiab txhim kho installation ceev.
Rau qhov chaw uas tsis tas yuav tsum tau disassembled, tsis txhob disassemble kom tsis txhob txo qhov raug ntawm mating ntawm cov khoom. Thaum disassembling nruj haum qhov chaw, siv cov cuab yeej tshwj xeeb kom deb li deb tau kom tsis txhob tsoo qhov chaw ncaj qha thiab tiv thaiv kev puas tsuaj rau cov khoom uas tshwm sim los ntawm disassembly.
2) Kev ntxuav
Ntxuav cov khoom tawg thiab cov khoom siv nrog cov roj av los yog cov tshuaj ntxuav tes thiab muab tso rau hauv pawg kom tsis txhob muaj kev tshuaj xyuas thiab tu.
3) Overhaul
Tshawb xyuas cov khoom ntxuav thiab cov khoom ib los ntawm ib qho thiab kho lossis hloov lawv raws li qhov hnyav ntawm qhov teeb meem pom. Cov khoom tshuaj ntsuam xyuas tseem ceeb rau txhua qhov khoom muaj raws li hauv qab no:
Main ncej mechanism: xyuas qhov clearance ntawm lub ntsiab ncej thiab lub tes tsho, spindle, thiab bearing. Yog tias qhov kev tshem tawm loj dhau los ntawm kev hloov kho, lub tes tsho lossis cov kabmob yuav tsum tau hloov.
Koob pas nrig mechanism: Thaum lub koob pas nrig yog qhov qis tshaj plaws, xyuas qhov sib txawv ntawm rab koob thiab lub tes tsho. Yog tias qhov sib txawv loj heev, lub koob pas nrig lossis lub tes tsho tuaj yeem hloov tau. Txheeb xyuas qhov xoob ntawm lub koob thiab sab sauv. Yog hais tias qhov ntau ntawm sab sauv thiab qis looseness tshaj tus nqi teev (high-speedoverlock tshuab xaws0.3mm, nruab nrab-ceev tshuab 0.8mm), cov saw txuas thiab saw pins yuav tsum tau hloov. Txheeb xyuas qhov hnav ntawm cov khoom sib txuas hauv rab koob bar mechanism. Yog tias qhov hnav tsis hnyav, nws tuaj yeem kho nrog cov ntaub ntawv zoo lossis cov ntawv xuab zeb. Yog tias qhov hnav hnyav heev, nws yuav tsum tau hloov. Txheeb xyuas qhov mob stroke ntawm rab koob bar mechanism thiab kho nws raws li txoj cai xaws.
Needle Bending Mechanism: Txheeb xyuas qhov hnav ntawm txhua qhov txuas ntawm rab koob khoov tshuab, kho qhov hnav me ntsis, thiab hloov tiag tiag; Tshawb xyuas lub viav vias reciprocating amplitude ntawm lub sab sauv thiab sab nraub qaum pins. Yog hais tias lub viav vias amplitude loj dhau lawm, lub ncej, txuas txuas, thiab txuas pas nrig ntsia hlau ntawm tus pin tuav yuav tsum tau hloov. Xyuas qhov degree ntawm looseness ntawm saw nuv koob nyob rau hauv tag nrho cov lus qhia. Yog tias looseness loj heev, nws txhais tau hais tias qhov cuam tshuam ntawm cov saw nuv koob yog hnav tiag tiag. Nws yog ib qho tsim nyog yuav tau xav txog kev hloov cov khoom xws li saw nuv rab koob tsav crank, saw nuv rab koob txuas pas nrig, thiab saw nuv rab koob txav slider.
Kev pub mis: Txheeb xyuas qhov hnav ntawm cov hlua txuas thiab cov cam, txuas rods thiab cranks, lifting swb, pub dev, nias, ko taw nias puag phaj, thiab lwm yam, kho me ntsis hnav, thiab hloov hnyav hnyav.
Cov txheej txheem txiav: tshuaj xyuas qhov hnav ntawm lub cutter tuav thiab sab sauv thiab sab cutters, kho qhov hnav ntawm lub cutter tuav, thiab zom cov hniav, thiab hloov lawv yog tias lawv tsis tuaj yeem kho.
Roj Circuit Court: Xyuas cov roj Circuit Court, roj qhov, thiab roj yeeb nkab kom smoothness, kev sib txuas, thiab kev ncaj ncees.
Lub cev muaj zog: xyuas qhov kev ruaj ntseg, khiav suab thiab kub ntawm lub cev muaj zog, qhov haum thiab kev khiav haujlwm ntawm lub clutch, qhov txuas thiab qhov tsis zoo ntawm lub cev muaj zog, thiab lubricate cov bearings ntawm lub cev muaj zog nrog butter.
4) Sib dhos thiab commissioning
Txhim kho cov koom haum, cov khoom siv, thiab cov khoom nyob rau hauv qhov kev txiav txim rov qab ntawm disassembly raws li lub hauv paus ntsiab lus ntawm sab hauv tawm, tom qab ntawd kho raws li cov qauv kev tso cai thiab kev ua haujlwm ntawm cov koom haum. Tom qab tag nrho cov kev hloov kho tau ua tiav, refuel lub tshuab, ua kom nws khiav manually, paub meej tias lub tshuab ua haujlwm zoo, tom qab ntawd txuas cov khoom siv hluav taws xob rau kev sim seam.
