Common Faults Ntawm Hydraulic Presses

Thaum lub sijhawm ua haujlwm ntawm cov hlau extrusion hydraulic xovxwm, bolts qee zaum poob tawm thiab poob rau hauv lub tog raj kheej hydraulic, ua rau muaj khawb loj ntawm phab ntsa plunger. Tom qab qhov teeb meem tshwm sim, cov txheej txheem ib txwm tsis tuaj yeem kho ntawm qhov chaw txhua. Nws tuaj yeem tsuas yog disassembled thiab xa mus rau cov chaw tsim khoom los kho vuam lossis scrapping thiab hloov. Txij li thaum tsis muaj cov khoom seem los hloov, lub sijhawm rau rov tsim cov khoom siv lossis rov qab mus rau lub Hoobkas kho tsis tuaj yeem tswj tau. Lub sij hawm ntev downtime ua rau poob nyiaj txiag loj rau lub tuam txhab, thiab kev ua haujlwm siab lossis kho cov nqi yuav tsum tau them. Yuav kom ua tau raws li qhov yuav tsum tau ua ntawm kev lag luam tas mus li, nws yog ib qho tsim nyog yuav tsum nrhiav kev yooj yim, nrawm, yooj yim thiab siv tau zoo los daws cov teeb meem ntawm cov cuab yeej siv, txo qis lub tuam txhab kev poob qis thiab lub sijhawm tsim khoom, thiab txo cov nqi tu thiab tu. Cov txheej txheem ntawm cov khoom siv polymer sib xyaw tuaj yeem siv rau kev kho ntawm qhov chaw
Cov kauj ruam ua haujlwm:
1. Siv cov nplaim hluav taws xob oxygen-acetylene los ci rau qhov khawb (tswj qhov kub thiab tsis txhob nto annealing), ci tawm cov roj uas tau nkag mus rau hauv cov hlau nto rau ntau xyoo, thiab ci kom txog thaum tsis muaj hluav taws.
2. Siv lub kaum sab xis grinder los kho qhov khawb nrog qhov sib tsoo qhov tob ntawm ntau tshaj 1 hli, thiab zom cov grooves raws phab ntsa sab nrauv ntawm lub tog raj kheej, nyiam dua dovetail grooves. Sib sib zog nqus qhov ntawm ob qhov kawg ntawm khawb kom hloov cov kev ntxhov siab.
3. Siv cov paj rwb dipped hauv acetone los yog anhydrous ethanol los ntxuav qhov chaw.
4. Siv cov khoom siv kho kom sib npaug sib npaug rau qhov chaw khawb; thawj txheej yuav tsum yog nyias, txawm thiab npog qhov khawb ntawm qhov chaw kom paub meej qhov zoo tshaj plaws adhesion ntawm cov khoom thiab cov hlau nto. Tom qab ntawd siv cov khoom siv rau tag nrho thaj chaw kho thiab nias ntau zaus kom paub meej tias cov khoom tau ntim thiab ncav cuag qhov xav tau tuab, ua rau nws siab me ntsis siab dua cov phab ntsa sab nrauv ntawm lub tog raj kheej.
5. Nws yuav siv sij hawm 24 teev rau cov khoom kom ua tiav ntau yam khoom ntawm 24 degree. Txhawm rau txuag lub sijhawm, qhov kub tuaj yeem nce ntxiv los ntawm lub teeb halogen tungsten. Rau txhua txhua 11 degree qhov kub thiab txias, lub sij hawm kho yuav luv luv los ntawm ib nrab. Qhov zoo tshaj plaws curing kub yog 70 degree.
6. Tom qab cov khoom kho tau zoo, siv cov pob zeb sib tsoo zoo los yog scraper los kho thiab theem cov khoom uas siab tshaj ntawm phab ntsa sab nrauv ntawm lub tog raj kheej, thiab kev tsim kho tiav.
