I. Tej yam tshwm sim ntawm to hauv lub taub hau tuag ntawm ib tug floating ntses noj pellet ua tshuab
Leakage Location thiab Manifestations
- Qhov chaw: Cov dej ntws feem ntau tshwm sim ntawm kev sib txuas ntawm lub taub hau tuag thiab flange flange, tuag lub taub hau sealing zawj, thiab nyob ib ncig ntawm lub qhov tuag.
- Khoom Leaked: Cov khoom xau feem ntau yog ib nrab-plasticized, siab- kub, thiab khov heev. Nws yooj yim adheres rau cov khoom nto.
- Kev coj cwj pwm: Raws li lub siab nce, cov dej ntws nce ntxiv. Hauv cov xwm txheej hnyav, cov dej ntws mus tas li, ua rau:
- Cov cuab yeej ua paug: Leaked khoom pollutesfloating ntses pub pellet txiag tshuabthiab ib puag ncig ib puag ncig.
- Kev cuam tshuam ntau lawm: Txo tus nqi extrusion, cov khoom tsis ruaj khov, thiab cov zis tsis sib xws.
Nrog Phenomena
- Kev Hloov Siab: Cov kev hloov pauv hauv chamber siab thiab tsis ruaj khov lub cev muaj zog tam sim no muaj ntau.
- Seal Aging: Cov ntsiab lus ntws tawm qhia qhov kub tsis zoo, ua rau kom nrawm nrawm ntawm cov ntsaws ruaj ruaj.
- Khoom siv pov tseg: Cov nqi tsim khoom nce ntxiv vim cov khoom siv pov tseg tseem ceeb thiab cov khoom siv tsis zoo.
- Kev Nyab Xeeb Kev Nyab Xeeb: Nyuaj tswj kev huv nyob ib puag ncigntses pub pellet txiag tshuabnce kev pheej hmoo ua haujlwm.
II.Tub ntxhais ua rau tuag taub hau Leakage hauv Ntses Pub Pellet Ua Tshuab
1. Sealing System Failure (Qhov Tseem Ceeb)
- Kev laus lossis kev puas tsuaj ntawm Gaskets: Qhov poob ntawm sealing kev ua tau zoo vim hnav - tawm los yog deformed gaskets (graphite, kauv- qhov txhab).
- Khoom tsim -Up: Accumululation thiab carbonization nyob rau hauv lub sealing groove ua rau ib tug uneven sealing nto, txo cov sealing zoo.
- Flange Bolt Teeb meem: Cov bolts xoob los yog tsis sib npaug ua rau lub sealing tsis txaus.
- Kev xaiv foob tsis raug: Cov ntsaws ruaj ruaj tsis haum rau siab -kub lossis siab - cov kev mob siab tsis ua kom muaj kev ncaj ncees.
2. Aquatic feed pellet zebteeb meem tuag thiab chim
- Uneven Sealing Nto: Hnav, deformation, los yog khawb ntawm lub taub hau tuag flange nto cuam tshuam lub sealing nto.
- Barrel Deformation: Deformation ntawm lub thoob lub qhov hluav taws xob flange tsim ntau clearance nrog lub taub hau tuag, ua rau to.
- Eccentric Installation: Misalignment ntawm lub taub hau tuag thiab lub thoob ua rau lub zog sealing tsis sib xws, ua rau kom xau.
- Tuag Qhov Hnav: Kev hnav hnyav ntawm lub qhov tuag ua rau cov khoom xau los ntawm qhov chaw ib puag ncig.
3. Cov txheej txheem thiab kev ua haujlwm
- Tshaj Chamber Siab: Kev kub siab dhau ntawm lub foob qhov kev cia siab ua rau cov dej xau.
- Tsawg Die Kub: Tsawg tuag lub taub hau kub ua rau cov khoom siv tsis zoo, ua rau compression - ntsig txog to.
- Siab Pub Tus Nqi: Cov nqi pub ntau ua rau muaj qhov hloov pauv siab thiab cuam tshuam tsis tu ncua, ua rau muaj dej ntau ntxiv.
- Kev kaw tsis raug: Ua tsis tiav cov khoom khoob ua ntej kaw yuav ua rau carbonization, uas ua rau lub sealing nto.
4. Kev teeb tsa tsis raug thiab kev saib xyuas ntawm cov dej pub pellet extruder
- Gaskets tsis zoo: Kev sib raug zoo tsis raug lossis wrinkles nyob rau hauv lub sealing gasket thaum lub sij hawm installation txo kev sealing kev ua tau zoo.
- Tsis muaj kev tshuaj xyuas: Cov ntsaws ruaj ruaj tsis raug tshuaj xyuas tas li, thiab cov ntsaws ruaj ruaj uas muaj hnub nyoog tsis hloov raws sijhawm, ua rau muaj peev xwm to.
- Kev puas tsuaj Sealing nto: Cov kab nrib pleb tshwm sim los ntawm kev tu tsis raug ntawm lub taub hau tuag tuaj yeem ua rau lub sealing nto, ua rau cov dej xau.
III. Targeted Solutions
1. Thaum muaj xwm ceev tuav cov dej pub pellet txiag tshuab tuag taub hau to
- Txo tus nqi noj: Tam sim ntawd txo tus nqi pub kom txo tau lub siab chamber thiab txo cov xau ntxiv.
- Kaw thiab Ntxuav: Tom qab kaw thiab txias, ntxuav cov khoom xau thiab cov khoom ntim hauv qhov sib khi.
- Kev soj ntsuam foob: Tshawb xyuas lub sealing gasket rau kev puas tsuaj thiab hloov cov laus los yog hnav cov ntsaws ruaj ruaj.
- Tighten Flange Bolts: Retighten bolts kom ntseeg tau tias txawm tias quab yuam kev faib tawm, kom ntseeg tau tias kev sib khi zoo.
- Coaxiality Calibration: Tshawb xyuas thiab calibrate lub coaxiality ntawm lub taub hau tuag thiab chim los tiv thaiv eccentricity thiab uneven sealing quab yuam.
2. Kev tiv thaiv txhua hnub raudej pub pellet ua tshuab
- Xaiv Cov Seals Zoo: Siv cov ntsaws ruaj ruaj uas ua los ntawm siab- cov ntaub ntawv zoo uas tuaj yeem tiv taus qhov kub thiab txias (piv txwv li, hlau kauv qhov txhab gaskets).
- Kev tshuaj xyuas tsis tu ncua: Tsis tu ncua tshuaj xyuas lub sealing nto rau khawb los yog deformations, thiab kho lawv raws li xav tau.

- Kev tsim nyog foob: Xyuas kom meej tias lub sealing gasket yog tiaj tus thiab ua kom zoo thaum lub sijhawm teeb tsa, nrog rau cov ntsia hlau nruj nruj raws li tus qauv.
- Txheej txheem kaw kom raug: Ib txwm ntim cov khoom ua ntej kaw kom tsis txhob muaj kev sib txuam thiab carbonization.
3. Ntev - lub sij hawm txij nkawm ntawm floating ntses noj pellet txiag tshuab
- Foob Hloov Lub voj voog: Tsim kom muaj lub voj voog hloov pauv tsis tu ncua (txhua 3-6 hnub) txhawm rau tiv thaiv kev poob qis.
- Kev tshuaj xyuas txhua hli: Ua txhua hli kev tshuaj xyuas ntawm qhov sealing nto, sealing Cheebtsam, thiab tuag taub hau mob. Tom qab txhua qhov disassembly, xyuas kom meej tias tag nrho cov khoom raug kuaj xyuas kom zoo.
- Kev cob qhia neeg ua haujlwm: Qhia cov neeg tsav tsheb hauv cov txheej txheem sealing kom raug thiab yuav ua li cas txhawm rau txheeb xyuas thiab daws cov teeb meem xau sai.
IV. Xaus
Cov dej xau hauv lub taub hau tuag ntawm lub tshuab ua khoom noj ntses ntab yog qhov teeb meem tseem ceeb uas tuaj yeem ua rau muaj kev cuam tshuam rau kev ua haujlwm, nce nqi, thiab kev pheej hmoo ntawm kev nyab xeeb. Los ntawm kev nkag siab covib txwm manifestations, tsom xam covcore ua, thiab kev sivphiaj xwm daws, manufacturers tuaj yeem txo cov kev pheej hmoo cuam tshuam nrog kev xau. Kev tshuaj xyuas tsis tu ncua, kev teeb tsa kom raug, thiab kev tiv thaiv kev saib xyuas yog qhov tseem ceeb rau kev ua kom lub sijhawm ntev - kev ua tau zoo thiab kev ntseeg siab ntawm extruder tuag hau.
