Extrusion khoom nyob rau hauv lub caij los nag

 

 

 

1. Tiv thaiv kom tsis txhob rov qab los ntawm cov dej nag, xyuas kom cov dej ntws tawm ntawm cov kab hluav taws xob, thiab siv hluav taws xob foob. Xav txog ib ntus tsa lub txee rau kev tiv thaiv dej yog tias xav tau.
2. Nce qhov pib ntawm chav faib khoom nkag. Me me seepage nyob rau hauv cable trenches feem ntau zoo vim cable sheathing yog waterproof. Khaws cov trench npog los tiv thaiv loj - cov dej nyab thiab cov kab hauv qab.
3. Txhawm rau tiv thaiv luv luv Circuit Court lossis blowouts, txiav fais fab tam sim ntawd ntawm lub ntsiab hloov thiab xa ib tus neeg saib. Lus Ceeb Toom: Yog tias dej nyob ib puag ncig ntawm lub txee, tsis txhob rub lub tes hloov pauv ntawm tes- siv cov pas nrig lossis cov ntoo qhuav, hnav cov hnab looj tes insulating thiab tsom iav kev nyab xeeb, thiab sawv ntsug ntawm cov ntaub thaiv npog kom tsis txhob muaj hluav taws xob thiab hluav taws xob.

 

 

1. Ua ntej tshuaj xyuas cov yeeb nkab ntau lawm kab txee. Yog tias muaj dej noo los yog dej nyab, tsis txhob siv nws. Ib tus kws tshaj lij hluav taws xob tsim nyog yuav tsum:

a. Siv lub ntsuas hluav taws xob los xyuas seb lub txee lub plhaub puas nyob.

 

b. Tshawb xyuas qis- cov khoom siv hluav taws xob- tswj circuits, breakers, relays, terminal blocks- kom ya raws. Qhuav lawv sai yog tias damp. Hloov tej yam uas pom tseeb rusted.

 

2. Ua ntej fais fab tuag, ntsuas qhov rwb thaiv tsev ntawm txhua qhov load cable-theem- mus rau-theem thiab theem- mus rau- hauv av. Rau qhov ntsuas hluav taws xob qis dua 500V, siv 500V megohmmeter; rwb thaiv tsev yuav tsum yog tsawg kawg yog 0.5MΩ. Qhuav thiab cua- ziab txhua yam khoom hauv lub txee.

 

 

Thawj qhov: VFD ntub dej tsis yog qhov teeb meem tiag tiag - ntub thiab ua kom muaj zog yog. Qhov ntawd feem ntau dhau los kho, thiab koj muaj hmoo yog tias nws tsis tawg. Yog tias nws raug dej nyab thaum tsis muaj hluav taws xob, nws tuaj yeem rov qab tau tag nrho. Yog tias dej nyab thaum khiav, kev puas tsuaj yog qhov tseeb, tab sis txiav fais fab tam sim ntawd los tiv thaiv cov xaim sab hauv los ntawm kev kub hnyiab thiab ua rau hluav taws. Kev tiv thaiv hluav taws yuav tsum nyob hauv qhov chaw.

Cov kauj ruam rau dej nyab tab sis tsis muaj zog VFD:

1. Tsis txhob siv zog. Qhib lub vaj huam sib luag thiab so txhua qhov chaw.
2. Siv lub tshuab ziab plaub hau rau qhov chaw txias kom qhuav cov zaub, PC boards, cov khoom siv hluav taws xob, cov kiv cua, thiab lwm yam. Tsis txhob siv cua kub - kub heev tuaj yeem ua rau cov khoom puas.
3. So cov saum toj no nrog 95% ethanol, ces tshuab- qhuav dua nrog cua txias.
4. Cua- ziab hauv qhov cua, qhov chaw ntxoov ntxoo rau ib teev, so nrog ethanol dua, thiab tshuab- qhuav nrog cua txias.
5. Cawv evaporation nqa tawm feem ntau cov dej noo. Tam sim no siv qis- qhov chaw cua sov los tshuab- ziab cov khoom dua.
6. Tsom ntsoov rau cov khoom no: potentiometers, hloov hluav taws xob hloov pauv, cov lus qhia (khawm), relays, contactors, reactors, kiv cua (tshwj xeeb tshaj yog 220V), electrolytic capacitors, fais fab modules. Siv cov cua kub tsawg thiab qhuav ntau zaus. Transformers, contactors, thiab fais fab modules yog qhov tseem ceeb.
7. Tom qab 6 kauj ruam, xyuas seb cov dej seem hauv qhov module. Tos 24 teev, xyuas dua kom rov qab los ntawm cov dej noo, thiab ziab cov khoom tseem ceeb ib zaug ntxiv.
8. Tom qab ziab, sim ua kom muaj zog -tab sis hloov nws tam sim ntawd tom qab. Saib VFD cov lus teb. Yog tias qhov qub, nws tuaj yeem siv tau.

 

Yog tias koj tsis tuaj yeem disassemble nws, cia li cia nws cua- qhuav rau ob peb hnub. Thaum tag nrho qhuav, tshuab lim compressed cua los ntawm qhov khoob kom tshem tawm cov av sab laug los ntawm cov dej nag, uas tuaj yeem ua rau tsis zoo cua sov dissipation thiab tswb kaw.

 

Cov kab hauv qab: tsuav yog dej nyab VFD tsis muaj zog, nws feem ntau zoo. Tib txoj kev siv rau PLCs, hloov cov khoom siv hluav taws xob, AC systems, thiab lwm yam boards.

 

 

1. Tshem tawm lub cev muaj zog, qhwv lub hwj chim cable, tshem tawm cov coupling, kiv cua npog, kiv cua, thiab lub kaus mom kawg. Tshem tawm lub rotor, qhib cov kabmob npog, thiab ntxuav cov kabmob nrog roj av lossis roj av. Hloov cov bearings yog hnav hnyav, ces rov- roj. Roj roj: ib nrab ntawm cov kabmob muaj peev xwm rau 2-ncej motors, ob-peb peb rau 4- thiab 6-ncej motors. Siv calcium-sodium puag high-speed roj.
2. Xyuas stator windings nrog 500V megohmmeter rau rwb thaiv tsev tiv thaiv ntawm theem thiab hauv av. Yog tias qis dua 0.5MΩ, qhuav cov windings. Ntxuav cov roj stains nrog roj av. Yog tias rwb thaiv tsev muaj hnub nyoog (xim xim av), preheat lub windings, thov insulating kua roj vanish, thiab qhuav. Txoj kev ziab kom qhuav:

a. Txoj kev teeb pom kev zoo: tsom cov qhov muag teev infrared ntawm lub windings, cua sov ib lossis ob qho kawg.

b. Lub qhov cub hluav taws xob lossis qhov cub hluav taws xob txoj kev: tso lub qhov cub hauv qab ntawm stator nrog nyias hlau phaj nruab nrab ntawm lawv kom tsis muaj cua sov. Npog lub stator nrog lub hau kawg thiab burlap. Tig lub stator nruab nrab ntawm kev ziab. Saib xyuas hluav taws- kua roj vanish thiab nws cov vapors yog cov nplaim taws.

 

 

Cov dej noo yog ib qho ua rau cov yeeb nkab ntau lawm kab lub cev muaj zog tsis ua haujlwm. Txau dej los yog condensation tuaj yeem nkag mus rau hauv lub cev muaj zog, tshwj xeeb tshaj yog tom qab lub hlis ntawm kev cia khoom. Nco ntsoov xyuas cov rwb thaiv tsev coil ua ntej siv, lossis koj pheej hmoo hlawv lub cev muaj zog. Cov txheej txheem rau damp motors:

1. Circulating cua kub kom qhuav: tsim kom qhuav chamber (piv txwv li, firebrick), nrog rau cov cua qhov hluav taws xob nyob rau sab saum toj thiab inlet ntawm sab. Khaws cua kub nyob ib ncig ntawm 100 degree.
2. Lub teeb ziab kom qhuav: tso ib lossis ob peb lub siab -wattage incandescent qhov muag teev (piv txwv li, 100W) hauv lub cev muaj zog. Khaws cov qij kom deb ntawm coils kom tsis txhob hlawv. Npog lub cev lub cev nrog canvas rau rwb thaiv tsev.
3. Desiccants:

a. Quicklime desiccant. Cov khoom tseem ceeb yog calcium oxide. Nws absorbs ya raws los ntawm cov tshuaj tiv thaiv kab mob -irreversible. Nws tuav lub peev xwm nqus tau ntau dua 35% ntawm nws tus kheej qhov hnyav tsis hais cov av noo, ua haujlwm zoo ntawm qhov kub thiab txias, thiab pheej yig.

b. Silica gel desiccant. Cov dej noo-permeable hnab ntawm ntau hom silica gel. Cov khoom tseem ceeb yog cov microporous hydrated silica ntau heev - tsis yog - tshuaj lom, tsis muaj ntxhiab, tshuaj lom neeg ruaj khov, nrog kev nqus dej muaj zog. kim dua.

4. Tus kheej- cua sov cua kom qhuav: rau cov tsis muaj cuab yeej lossis kev paub. Siv sijhawm ntev dua. Ib txwm sim lub cev muaj zog rwb thaiv tsev ua ntej lub zog.

 

Tsis tas li ntawd: kom tsis txhob muaj hluav taws xob poob siab los ntawm cov dej seem hauv cov yeeb nkab ntau lawm kab, tom qab paub tseeb tias cov cuab yeej qhuav tag, cia nws nyob hauv qhov cua, qhov chaw qhuav li ntawm ib lub lis piam ua ntej siv. Tshawb xyuas cov xaim hauv av- dej tuaj yeem ua rau luv luv hauv av.

 

Yog tias koj tsis tuaj yeem kho koj tus kheej, tiv tauj peb rau kev tshuaj xyuas thiab kho kom tsis txhob muaj kev puas tsuaj.
