1. Ukulungiswa kokukhushulwa kwengaphezulu kwezinyo

Ukwanda kwemvume kuvame ukubangelwa ukwanda kwemvume phakathi kwe-shaft kanye nomgodi we-sleeve, ngakho-ke imvume kufanele ibuyiselwe ngemva kokulungisa ukulingana kwe-shaft kanye nomkhono. Uma ukugqokwa kwe-pump cavity kungeyona into engathi sína, i-alloy ethwalayo ingashiselwa phezulu kwezinyo, bese iguqulwa ngokuya ngezidingo zokulingana. Uma i-pump cavity nayo igugile kakhulu, indlela ye-sleeve yamukelwa ukuze ilungiswe. Indlela iwukuthi: ukubhodla udonga lwesigxobo sepompo, futhi ukuguqula i-semicircular bushing enogqinsi oluyi-3 kuya ku-4 mm ngokuhambisana nobukhulu bomgodi wepompo ngensimbi noma ithusi. Ngemuva kokuthi umkhono wehliselwe emgodini wepompo, uboshwe nge-clamp, bese ushiselwa kuwo wonke ububanzi be-bushing emikhawulweni yomibili, bese upholisa kancane ebhokisini lesihlabathi ngemuva kokushisela. Ekugcineni, i-cavity yepompo inesithukuthezi ngobukhulu obujwayelekile, futhi i-taper yayo ne-ovality ayikhulu kune-0.02 mm. I-bushing ingabuye ihlanganiswe ne-epoxy resin glue.

2. Ukulungiswa kokukhishwa kwe-gear meshing eyengeziwe

Ukususwa kohlangothi lwezinyo kunomphumela omncane ekusebenzeni kwepompo yamafutha, ngakho-ke inani elivumelekile likhulu, ngezinye izikhathi lifinyelela ku-1 mm, ngakho-ke kukhona ukulungiswa okumbalwa. Uma izinyo legiya libushelelezi noma linezinyosi ngemuva kokugqoka, lipholisha ngetshe likawoyela. Njengoba amazinyo epompo egqokwa ohlangothini olulodwa, igiya lingashintshwa futhi lisetshenziswe lapho ukuguga kokuqina kwezinyo kungadluli inani elivumelekile; uma idlula inani elivumelekile, kufanele ishintshwe noma ilungiswe.

3. Ukulungiswa kokukhuphuka kokususwa kobuso

Ukuvunyelwa kobuso bokuphela kunomthelela omkhulu ezinkomba zokusebenza zepompo yamafutha (umfutho wamafutha, umthamo wamafutha). Uma imvume yobuso bokuphela idlula izinga, kufanele ilungiswe. Izinyathelo zokulungisa zimi kanje:

(1) Uma iphansi legumbi lokumpompa ligqokile, ukupholishwa kufanele kusetshenziselwe ukuqeda ukubobotheka endaweni egugile.

(2) Uma isiphetho segiya nesembozo sephampu kugqokwa, uma ukugqokwa kungebucayi, indawo engaphezulu ingambozwa ngesihlabathi esiqhumayo futhi igaywe endaweni yesikhulumi (noma ingilazi) ukuze kuqedwe izimpawu zokuguga nokungalingani; uma ukugqokwa kubucayi futhi imvume yobuso bokuphela inkulu, ingalungiswa ngokugaya noma ukuguqula kuqala bese ugaya.

Lapho kugaywa, ubude bobuso bokuphela kwegiya ngaphansi kobuso bokuphela kwendlu (okungukuthi, ukuphuma kokuphela kwezinyo) kufanele buhlale bubhekwa ngegeji yokujula noma i-micrometer. Ngemuva kokugaya, umzimba wepompo kufanele ube nendawo yokukhwelana ebheke emgqeni ophakathi wembobo ye-shaft. I-non-perpendicularity (noma ukuchezuka kwayo) ngokuvamile asikho ngaphezu kuka-0.1 mm ku-100 mm, futhi ukungalingani kwendawo yokukhwelana ngokuvamile akuba ngaphezu kuka-0.02 mm.

4. Ukulungiswa kwemvume eyengeziwe phakathi kwe-oil pump shaft kanye ne-bearing

Njengoba ukuvuleka phakathi kwe-shaft ne-bearing kwanda, i-meshing evamile ye-gear pair izobhujiswa, futhi i-tooth top izogudla emgodini wepompo, ibhubhise ubuhlobo obuhambisanayo bengxenye ngayinye futhi inciphise ukunikezwa kukawoyela. Lapho imvume phakathi kwe-shaft yokushayela kanye ne-bearing inkulu kakhulu, indlela yesayizi yokulungisa ingasetshenziselwa ukulungiswa, imbobo ye-shaft ingakhuliswa (ingakhuliswa ngo-0.25 mm, 0.50 mm), futhi i-shaft yokushayela ingaqiniswa ngokufanele. (i-iron plating noma i-chrome plating), noma ingalungiswa ngendlela ye-sleeve (ugqinsi lwemikhono lungaba ngu-15 mm), kanye nokugxila kwemikhono engaphezulu nephansi kufanele kuqinisekiswe ngesikhathi sokukhulelwa. Ngenxa yalesi sizathu, amaphampu kawoyela anemikhono ethwalayo esembozweni sepompo, kungcono ukufaka ikhava yepompo emzimbeni wepompo bese uqedela ukucubungula ngesikhathi esisodwa. I-taper ne-ovality yembobo yokuthwala akufanele idlule i-0.02 mm. Ngemuva kokulungiswa, ukungaqondi kahle kwe-shaft akufanele kudlule u-0.05 mm ngaphezu kobude bonke. Lapho imvume phakathi kwe-passive gear shaft kanye nembobo ye-shaft inkulu kakhulu, le ndlela engenhla ingase isetshenziselwe ukulungiswa. Endabeni yokugqokwa okuncane, njengoba i-passive gear shaft inganyakazi, ukugqokwa kwayo kuwukugqokwa okuhlangene, ngakho-ke i-shaft ingacindezelwa futhi iguqulwe ibe ngu-180 ° bese icindezelwa ukuze isetshenziswe (ngalesi sikhathi, uma ukuphazamiseka kwe-static fit kuncishisiwe. , ingalungiswa nge-electroplating). Ngemuva kokuthi i-shaft icindezelwe emzimbeni wepompo, ikhanda le-shaft kufanele licwile endaweni ehlangene yezindlu ngo-0.05-0.50 mm. Ngemva kokugqokwa kwembobo ye-shaft egiyeni le-passive, ilungiswa ngendlela yemikhono. Ngemuva kokulungiswa, imbobo yamafutha okugcoba kufanele ibhojwe ngokuvumelana nezidingo zokuqala.

5. Ukulungiswa kokukhuphuka kwe-axial clearance ye-shaft esebenzayo

Uma lokhu kugunyazwa kudlula inani elivumelekile, kulungiswa ngokubeka phezulu noma ukwengeza i-gasket ekugcineni kwangemuva kwendlu yephampu. Ngesikhathi sokulungiswa, kufanele kuqinisekiswe ukuthi le mvume ayinkulu kunokukhishwa kwezinyo.
