Itywina lomatshini likwabizwa ngokuba sisitywina sobuso bokugqibela, esinobuso obubini obujonge kwi-axis yokujikeleza, isiphelo sobuso phantsi koxinzelelo lolwelo kunye nembuyekezo yamandla omatshini angaphandle, ngokuxhomekeke kukulungelelaniswa kwetywina elincedisayo kunye esinye isiphelo ukugcina kufanelekile, kunye isilayidi isihlobo, ukuze kuthintelwe ukuvuza ulwelo. I-Credo Pump ishwankathela oonobangela bokuvuza okuqhelekileyo kwempompo yamanzi ngomatshini wokutywina:

Ukuvuza okuqhelekileyo okwenzekayo

Umyinge wokuvuza kwetywina ngoomatshini ubalelwa ngaphezulu kwe-50% yazo zonke iimpompo zolondolozo. Umgangatho wokusebenza kwetywina lomatshini uchaphazela ngokuthe ngqo ukusebenza okuqhelekileyo kwempompo. Ishwankathelwa kwaye ihlalutywe ngolu hlobo lulandelayo:

1. Ukuvuza kwamaxesha athile

I-Pump rotor shaft channel yesantya, isitywina esincedisayo kunye nokuphazamiseka okukhulu kwe-shaft, i-ring eshukumayo ayikwazi ukuhamba ngokuguquguqukayo kwi-shaft, xa ipompo iguqulwa, i-ring eguquguqukayo kunye ne-static inxibe, akukho ntlawulo yembuyekezo.

Imilinganiselo yokuchasana: Kwindibano yokutywinwa komatshini, umfutho we-shaft we-shaft kufuneka ube ngaphantsi kwe-0.1mm, kunye nokuphazamiseka phakathi kwetywina elincedisayo kunye ne-shaft kufuneka ibe yimodareyitha. Ngelixa uqinisekisa itywina le-radial, iringi eshukumayo inokushukunyiswa ngokuguquguqukayo kwi-shaft emva kokudityaniswa (iringi eshukumayo inokubotshwa ngokukhululekileyo ubuyele entwasahlobo).

2. Ioyile yokuthambisa engonelanga kumphezulu wokutywina iya kubangela ukukhuhlana okomileyo okanye uzobe isiphelo sesitywina sobuso.

Imilinganiselo yokuchasana: Ubude bomgangatho we-oyile yokuthambisa kwigumbi le-oyile kufuneka bube phezulu kunomphezulu wokutywina weendandatho ezihambayo kunye nezizinzileyo.

3. Ukungcangcazela ngamaxesha erotor. Isizathu kukuba i-stator kunye ne-top and low end covers ayilinganisi i-impeller kunye ne-spindle, i-cavitation okanye ukuthwala umonakalo (ukunxiba), le meko iya kunciphisa ubomi bokutywinwa kunye nokuvuza.

Amanyathelo okunqanda: Ezi ngxaki zingentla zinokulungiswa ngokwemigangatho yolondolozo.

Ukuvuza ngenxa yoxinzelelo

1. Ukuvuza kwetywina lomatshini okubangelwa luxinzelelo oluphezulu kunye namaza oxinzelelo ngenxa yoxinzelelo oluthe kratya lwasentwasahlobo kunye noyilo loxinzelelo olupheleleyo olukhethekileyo kunye noxinzelelo kwigumbi lokutywina elidlula i-3MPa, liya kwenza uxinzelelo oluthile kwisiphelo sokutywinwa lube lukhulu kakhulu, lwenza kube nzima. ukuze kwenziwe ifilimu elulwelo, ukunxitywa okumandla kubuso obutywiniweyo, ukonyuka kwexabiso le-calorific kwaye kubangele ukuguquka kwe-thermal kumphezulu wokutywina.

I-Countermeasures: kwi-seal machine seal, ukunyanzeliswa kwentwasahlobo kufuneka kuqhutywe ngokuhambelana nezibonelelo, ungavumeli into enkulu kakhulu okanye encinci kakhulu, iimeko zoxinzelelo oluphezulu phantsi kwesitywina somatshini kufuneka zithathe amanyathelo. Ukuze wenze isiphelo ubuso amandla ingqiqo, kangangoko kunokwenzeka ukunciphisa deformation, kunokusebenzisa ingxubevange enzima, iiseramikhi kunye nezinye izinto kunye namandla aphezulu compressive, kwaye womeleze amanyathelo okuthambisa ukupholisa, khetha imo yothumelo, ezifana isitshixo, pin, njl.

2. ukuvuza kwempompo yempompo yomatshini wokuvuza okubangelwa kukusebenza kwinkqubo yokuqala, ukuyeka, ngenxa yokuvaleka kwempompo yokungena, ukumpompa okuphakathi okuqulethe igesi, kunokubangela umgodi wokutywina ongalunganga, umngxuma wokutywina ukuba uxinzelelo olubi, ukukhuhlana okomileyo. kubangela amatywina, udidi olwakhelwe ngaphakathi lwetywina lomatshini luya kuvelisa (amanzi) into evuzayo, itywina levacuum kunye nomahluko woxinzelelo olulungileyo umahluko wesalathiso sento, kunye nokuguquguquka kokutywinwa koomatshini kunendlela ethile.

I-Countermeasure: Yamkela isiphelo esiphindwe kabini sokutywinwa kobuso, kuyanceda ukuphucula imeko yokuthambisa kunye nokusebenza kwesitywina.

Ukuvuza okubangelwa liphakathi

1. Uninzi lwe-submersible pump mechanical seal dismantling, i-static ring kunye ne-ring ring encedisayo ye-inelastic, enye ibolile, ibangele ukuvuza okukhulu kwesitywina somatshini kunye nokusila i-shaft phenomenon. Ngenxa yobushushu obuphezulu, iasidi ebuthathaka kugutyulo, isiseko esibuthathaka kumsesane omileyo kunye neringi eshukumayo encedisana nerubha yetywina, okukhokelela ekubeni ukuvuza komatshini kukhulu kakhulu, kuguquguqukayo kunye nesixhobo sokutywina serubha se-nitrile --40, ukumelana nobushushu obuphezulu, iasidi. -i-alkali ukumelana, xa ugutyulo lune-asidi kunye ne-alkaline kulula ukubola.

Imilinganiselo yokuchasana: kumajelo eendaba ezonakalisayo, iindawo zerabha kufuneka zikwazi ukumelana nobushushu obuphezulu, ukunganyangeki kweasidi ebuthathaka, i-alkali fluororubber ebuthathaka.

2. Ukuvuza kwetywina lomatshini okubangelwa kukungacoceki kwamasuntswana aqinileyo. Ukuba amasuntswana aqinileyo ebusweni betywina, aya kunqunyulwa okanye akhawulezise amatywina okuguga kunye nokukrazula, isikali kunye nokuqokelelwa kwe-oyile kumphezulu we-shaft (iseti), ngesantya esikhawulezayo kunesantya sokunxitywa kwe-friction pair, iringi inako. 't ukubuyisela ukufuduswa kwe-abrasion, isibini esinzima ukuya kolukhuni sisebenza ixesha elide kunobunzima kwiperi yefriction yegraphite, ngenxa yamasuntswana aqinileyo afakwe umphezulu we-graphite wokutywina umsesane wokutywina.

I-Countermeasure: Isitywina somatshini we-tungsten carbide friction pair kufuneka ikhethwe kwindawo apho iincinci eziqinileyo zilula ukungena.

Ngenxa yezinye iingxaki ezibangelwa ukuvuza kwamatywina omatshini amatywina omatshini asekhona kuyilo, ukhetho, ukufakwa kunye nezinye iindawo ezingenangqondo.

1. Ukunyanzeliswa kwentwasahlobo kufuneka kuqhutywe ngokuhambelana nemigaqo, kwaye akuvumelekanga ukuba ibe nkulu okanye incinci. Impazamo yi ±2mm.

2. Isiphelo sobuso beshafti (okanye umkhono weshafti) ukufakela iringi yokutywina eshukumayo kunye nesiphelo sobuso bedlala lokutywina (okanye iqokobhe) ukufakela iringi emileyo yokutywina kufuneka ikrolwe kwaye ipoliswe ukuthintela ukonakaliswa kweringi yokutywina emileyo ngexesha lokudityaniswa.
