Uhlalutyo lwezizathu zokungcangcazela kwe impompo yeinjini ethe nkqo

1. Ukungcangcazela okubangelwa kufakelo kunye nokutenxa kwindibanoimpompo yeinjini ethe nkqo
Emva kofakelo, umahluko phakathi komgangatho womzimba wempompo kunye ne-thrust pad kunye nokuma kombhobho wokuphakamisa kuya kubangela ukungcangcazela komzimba wempompo, kwaye ezi xabiso ezintathu zokulawula nazo zihambelana nomlinganiselo othile. Emva kokuba umzimba wempompo ufakwe, ubude bombhobho wokuphakamisa kunye nentloko yepompo (ngaphandle kwesikrini sokucoca) yi-26m, kwaye zonke zimisiwe. Ukuba ukuphambuka okuthe nkqo kombhobho ophakamisayo kukhulu kakhulu, ipompo iya kubangela ukungcangcazela okukhulu kombhobho wokuphakamisa kunye ne-shaft xa ipompo ijikeleza. Ukuba umbhobho wokuphakamisa uphezulu kakhulu, uxinzelelo olutshintshileyo luya kuveliswa ngexesha lokusebenza kwempompo, okubangelwa ukuphuka kombhobho wokuphakamisa. Emva kokuba impompo yomthombo onzulu ihlanganiswe, impazamo yokuqina kombhobho wokuphakamisa kufuneka ilawulwe ngaphakathi kwe-2mm ngaphakathi kobude obupheleleyo. Impazamo ethe nkqo nethe tyaba yi-0 pump.05/l000mm. Ukunyamezela kwe-static balance ye-pump head impeller ayikho ngaphezu kwe-100g, kwaye kufuneka kubekho i-8-12mm ephezulu kunye ne-serial clearance ye-serial emva kokuhlanganisana. Impazamo yofakelo kunye nendibano yokucoca sisizathu esibalulekileyo sokungcangcazela komzimba wempompo.

2. Isivunguvungu se-shaft yokuqhuba yempompo
I-Whirl, ekwabizwa ngokuba yi "spin", kukungcangcazela okuzenzelayo kweshafti ejikelezayo, engenazo iimpawu zokungcangcazela kwasimahla kwaye ingelulo uhlobo lokungcangcazela ngenkani. Ibonakaliswe ngokunyakaza okujikelezayo kwe-shaft phakathi kweebheringi, engenzekiyo xa i-shaft ifikelela kwisantya esibalulekileyo, kodwa iyenzeka kuluhlu olukhulu, olungaphantsi kwesantya se-shaft ngokwayo. Ujingi lwempompo yequla elinzulu lubangelwa ikakhulu kukunganelanga kokuthambisa. Ukuba i-gap phakathi kwe-shaft kunye ne-bearing inkulu, i-direction of rotation ichasene ne-shaft, ebizwa ngokuba yi-shaking of the shaft. Ngokukodwa, i-shaft ye-drive yepompo yepompo enzulu ide, kwaye imvume efanelekileyo phakathi kwe-rubber bearing kunye ne-shaft yi-0.20-0.30mm. Xa kukho ucoceko oluthile phakathi kwe-shaft kunye ne-bearing, i-shaft ihluke kwi-bearing, umgama ophakathi mkhulu, kwaye ukucocwa akunalubrication, njenge-deep well pump rubber bearing lubrication Umbhobho wokuhambisa amanzi uphukile. Ivaliwe. Ukusetyenziswa ngendlela engeyiyo kukhokelela kunikezelo lwamanzi lwaneleyo okanye olungafikanga ngexesha, kwaye kusenokwenzeka ukuba lungcangcazele. Ijenali inxibelelana kancinci nerabha. Ijenali iphantsi kwamandla e-tangential wokuthwala. Ulwalathiso lwamandla luchasene nolwalathiso lwesantya se-shaft. Kwicala lokusikwa kwindawo yoqhagamshelwano yodonga oluthweleyo, kukho utyekelo lokuya ezantsi, ngoko ke ijenali iqengqeleka ecaleni kodonga oluthweleyo, olulingana nepere yegiya zangaphakathi, zenza intshukumo ejikelezayo echasene necala lendlela. ukujikeleza kweshaft.

Oku kuye kwaqinisekiswa yimeko ekusebenzeni kwethu kwemihla ngemihla, okuya kubangela ukuba i-rubber bear ivutha ixesha elide.

3. Ukungcangcazela okubangelwa kukugcwala kakhulu kwempompo yeinjini yeinjini ethe nkqo
I-thrust pad yomzimba wempompo ithatha i-tin-based babbitt alloy, kunye nomthwalo ovumelekileyo yi-18MPa (180kgf/cm2). Xa umzimba wempompo uqaliswa, i-lubrication ye-thrust pad ikwimeko ye-lubrication yomda. Ivalve yebhabhathane yombane kunye nevalve yesango yesandla ifakwe kwindawo yokuphuma kwamanzi kumzimba wempompo. Xa impompo iqalisa, vula ivalve yebhabhathane yombane. Ngenxa yokubekwa kwe-silt, ipleyiti yevalve ayikwazi ukuvulwa okanye i-valve yesango ye-manual ivaliwe ngenxa yezinto zabantu, kwaye ukukhupha akukho ngexesha elifanelekileyo, okuya kubangela ukuba umzimba wempompo ushukume ngamandla kwaye i-thrust pad iya kutshisa ngokukhawuleza.

4. Ukungcangcazela kwesiphithiphithi kwindawo yokuphuma yempompo yeinjini ethe nkqo. 
Izixhobo zokumpompa zibekwe ngokulandelelana. Dg500 umbhobho omfutshane. Khangela ivalve. Ivalve yebhabhathane yombane. Ivalve yesandla. Umbhobho ongundoqo kunye nesinqamuli sehamile samanzi. Intshukumo ephazamisayo yamanzi ivelisa into engaqhelekanga yokubetha. Ukongeza kwi-valve nganye, ukuchasana kwendawo kukhulu, okubangelwa ukunyuka kwesantya kunye noxinzelelo. Utshintsho, olusebenza kwi-vibration yodonga lombhobho kunye nomzimba wempompo, unokubona i-pulsation phenomenon yexabiso lokulinganisa uxinzelelo. Uxinzelelo lwe-pulsating kunye neendawo zesantya ekuhambeni kwesiphithiphithi zigqithiselwa ngokuqhubekayo kumzimba wempompo. Xa isantya esiphezulu sokuqukuqela kwesiphithiphithi sifana nesantya sendalo sempompo yempompo yequla elinzulu, inkqubo kufuneka ifunxe amandla kwaye ibangele ukungcangcazela. Ukunciphisa umphumo wale ntshukumo, i-valve kufuneka ivule ngokupheleleyo kwaye i-spool kufuneka ibe ubude obufanelekileyo kunye nenkxaso. Emva kolu nyango, ixabiso lokungcangcazela lancitshiswa kakhulu.

5. Ukungcangcazela kwe-torsional yempompo ethe nkqo
Ukudityaniswa phakathi kwempompo enzulu ye-shaft enzulu kunye ne-motor ithatha i-elastic coupling, kwaye ubude be-shaft yokuqhuba yi-24.94m. Ngethuba lokusebenza kwempompo, kukho i-superposition ye-vibrations eziphambili zee-angular frequencies ezahlukeneyo. Isiphumo sokudityaniswa kweeresonances ezimbini ezilula kwii-angular frequencies azikho i-harmonic vibration, oko kukuthi, ukungcangcazela kwe-torsional kunye needigri ezimbini zenkululeko kumzimba wempompo, ongenakuthintelwa. Olu ngcangcazelo luchaphazela kakhulu kwaye lonakalise ii-thrust pads. Ngoko ke, kwimeko yokuqinisekisa ukuba iplani yokutyhala yenqwelomoya nganye ineweji yeoli ehambelanayo, tshintsha i-oyile engama-68# echazwe kwisixhobo soqobo semiyalelo engacwangciswanga ukuya ku-100# i-oyile ukunyusa i-viscosity ye-oyile yokuthambisa ye-oyile kwaye uthintele ifilimu yokuthambisa yehydraulic. kwi-thrust pad. ukuqulunqwa kunye nokugcinwa.

6. I-Vibration ebangelwa yimpembelelo edibeneyo yeepompo ezifakwe kwi-beam efanayo
Impompo yomthombo onzulu kunye nemoto zifakwe kumacandelo amabini e-1450 mmx410mm kwimiqadi yesakhelo eqinisiweyo, ubunzima obugxininisiweyo bempompo nganye kunye nemoto yi-18t, ukushukuma okusebenzayo kweempompo ezimbini ezikufutshane kumqadi wesakhelo enye enye inkqubo yeVibration yasimahla emibini. Xa i-vibration enye yeemoto idlula umgangatho ngokunzulu kwaye uvavanyo luqhuba ngaphandle komthwalo, oko kukuthi, ukudibanisa i-elastic ayixhunyiwe, kwaye ixabiso le-amplitude yemoto yomnye umpompo ekusebenzeni okuqhelekileyo liphakama ukuya kwi-0.15mm. Le meko akulula ukuyibhaqa, kwaye ingqalelo kufuneka ihlawulwe kuyo.
