Chikonzero Ongororo ye500KVA Diesel Generator Abnormal Bush Kupisa Kukanganisa

Injini yedhiziri chikamu chikuru che500KVA dhiziri jenareta, pane zvikonzero zvakawanda zvinokonzeresa kupisa injini yedhiziri.Kushaikwa kweoiri yeinjini muinjini yedhiziri ndicho chimwe chezvikonzero zvikuru neinjini yedhiziri inopisa.Kana injini yedhiziri ichishanda isina mafuta, inofanira kupisa gwenzi, asi gwenzi rinogona kupiswa kana pasina kushaikwa kwemafuta.

Nhasi, simba reDingbo, a dhiziri jenareta mugadziri , yakaongorora zvikonzero zvekupisa zvisina kujairika kwegwenzi 500KVA jenareta redhiziri.Ndinovimba kuti chinyorwa ichi chinobatsira kwauri.

1. Kuongorora kwechikonzero

Mune yakajairika kushanda kweinjini yedhiziri, pane kucheneswa pakati pecrankshaft rejenari uye inotakura gwenzi uye firimu remafuta riripo kuti rigadzire mafuta ekuzora.Nenzira iyi, kurasikirwa kwekukwevera kuduku, kupisa kunokonzerwa nekuputika kuduku, kupisa kunotorwa nemafuta, uye kutonhora kwekushanda kwakajairika.Kana gwenzi rinotakura rakabatana zvakananga nejenari kuti riite chikamu chakaoma chekukwesha nyika, iyo friction simba rekushandisa rinowedzera zvakanyanya, uye huwandu hukuru hwekupisa huchagadzirwa, hunozobviswa negwenzi rinotakura, uku kupisa. kubviswa nemafuta hakusi kuwanda.Kupisa kuchaungana mugwenzi rinotakura uye tembiricha ichakwira nguva dzose.Kana tembiricha ichipfuura iyo alloy melting point pane inotakura gwenzi, iyo inotakura gwenzi repamusoro rinotanga kunyungudika kusvika kupisa kwaitika, zvichikonzera kutadza kweinjini yedhiziri.

2. Zvinhu zvakakodzera zvinokonzera kukundikana

A. Tembiricha yemafuta yakakwira zvakanyanya kana yakaderera

Kana tembiricha yemafuta yakadzikira, viscosity yemafuta ekuzora yakakwira zvakanyanya uye fluidity haina kunaka.Kunyanya muchikamu chinotonhora chekutanga, huwandu hwemafuta hunopinda mu crankshaft hushoma, izvo zviri nyore kuita gwenzi rinotakura rakanangana nejenari re crankshaft uye nekukasira kupfeka uye kukuvara kwekubereka.Kana tembiricha yemafuta yakakwira zvakanyanya, viscosity yemafuta ekuzora yakadzikira uye simba refirimu remafuta rinodzikira, zvichikonzera kutetepa kwemafuta emufirimu, izvo zvakare nyore kukonzera kupera kwekutanga uye kukuvara kweiyo mafuta. kubereka gwenzi.Zvinowanzotendwa kuti tembiricha yepamusoro yeinjini yekuzora mafuta ndeye 130 ℃.Nekudaro, kuti uwedzere zvizere hupenyu hwebasa rekutakura, tembiricha yakajairika inofanirwa kuchengetwa muhuwandu hwe95 ~ 105 ℃.

B. Thermal oxidation kugadzikana kwemafuta ekuzora

Iyo yekupisa oxidation kuramba kwemafuta ekuzora ine mhedzisiro yakakosha pakuzora pakati pe crankshaft uye kubereka.Kana maoiri maviri akasiyana ekuzora akashandiswa pane imwechete prototype uye achishanda achienderera pasi peiyo yakafanana mamiriro ekushanda, mhedzisiro yakayerwa ichave yakasiyana.

C.Improper bearing assembly clearance

Kuti uvandudze nzvimbo yekuzora yeinjini yedhiziri iripo uye kudzivirira kupisa, kubvumidzwa pakati pekutakura nejenari re crankshaft kunofanirwa kudzorwa zvichinyatsoenderana nezvinodiwa zvebhuku rekushandisa dizeli.Paunenge uchitsiva gwenzi rinotakura, tarisa kutenderera uye cylindricity ye crankshaft journal.Kana ikadarika muganho, inokwenenzverwa kudzivirira kudzikisa nzvimbo yekusangana yejenari uye inotakura gwenzi uye kuwedzera kudzvanywa pane imwe unit nzvimbo.Mukuwedzera, iyo axial clearance ye crankshaft ichadzorwa.Kana kupfeka kwakapfuura muganhu, ichagadziriswa nenguva.

D. Kuora kwemafuta ekuzora

Kazhinji, panguva yekushandiswa kwemafuta ekuzora, nekuda kwekupfeka kweinjini yedhiziri silinda liner uye piston mhete, pamwe nekushandurwa kwepiston ring yekuvhura clearance uye nzvimbo yekuvhura, iyo yakakwirira-tembiricha uye yakanyanya-kudzvanywa musanganiswa unopisa unoyerera uchiyerera uchipinda mukati. crankcase iri kuwedzera, iyo isingango wedzera tembiricha yemafuta ekuzora, asi zvakare inomhanyisa iyo oxidation uye polymerization yemafuta ekuzora.Panguva imwecheteyo, nekuda kwekusanganiswa kwezvigadzirwa zvinopisa injini yedhiziri, kusanganiswa kweguruva rekunze uye simbi inopfeka marara, uye kushandiswa kwezvinowedzera mumafuta ekuzora, kushatisa uye kuparara kwekumhanya kwemafuta ekuzora kunowedzera zvakanyanya.Izvi hazvisi kungowedzera kupfeka uye kuora kweiyo friction pair ye lubricating chikamu cheinjini yedhiziri, asi zvakare ndicho chikonzero chikuru chekupisa kurasikirwa kwekubereka.

E. Hunhu husina kunaka hwemafuta ekuzora

Injini yedhiziri inoshandisa yakaderera mafuta ekuzora kana fake yemhando yepamusoro yekuzora mafuta mukushandiswa.Kana iyo yemhando yegiredhi yemafuta ekuzora isingaite zvinodiwa nedhiziri inogadzira injini, zvinotungamira kune Bush kupisa kutadza kweinjini yedhiziri.

F. Dambudziko rekubereka gwenzi

Kana zvinhu zvakaderera zvichishandiswa, kukwirira kwekushisa kwepamusoro uye kukwanisa kutakura kwegwenzi rinotakura hazvina kukwana.Kunyangwe kana kudzvanywa kwemafuta kuri kwakajairika uye huwandu hwemafuta hwakakwana, iyo Bush yekupisa kukanganisa ichakonzerwa.

G. Kuzunguzika kweinjini yedhiziri yakakura zvakanyanya panguva yekushanda

Kudengenyeka kweinjini yedhiziri panguva yekushanda kwakakura zvakanyanya nekuda kwekuvhunduka kubatwa kwekukuvara kana zvimwe zvikonzero;Zvingave zvakare kuti iyo inonyorovesa yeinjini yedhiziri crankshaft pachayo yakakuvadzwa, izvo zvinoita kuti injini yedhiziri crankshaft idengenyeke zvakanyanya;Mushure mekushanda kwenguva refu, gwenzi rinobereka rinogona kuregedzera, zvichikonzera kupisa kwegwenzi kana kutsvedza.

H. Tembiricha yeinjini yedhiziri yakakwira zvakanyanya

Nekuda kwekutadza kutonhora kana zvimwe zvikonzero, tembiricha yese uye tembiricha yemafuta einjini yedhiziri yakakwira zvakanyanya, zvichikonzera kutadza kupisa kweBush kweinjini yedhiziri mushure mekushanda kwenguva refu.

3. Chengetedzo yekushandisa 500kva dhiziri jenareta

a.Kugara uchigadzirisa: chenesa zvikamu, dredge nzira yemafuta, wedzera kana shandura mafuta nenguva kudzivirira mafuta kubva mukukwegura kana kusvibiswa zvakanyanya uye kuvhara nzira yemafuta.

b.Sarudza mafuta ekuzora anosangana nezvinodiwa nemugadziri weinjini yedhiziri uye nyatso chengetedza sezvinodiwa.

c.Usati watanga injini yedhiziri, nyatsotarisa huwandu hwemafuta ekuzora.Kana isina kukwana, wedzera maererano nemitemo.

d.Munguva yekutonhora kwekutanga-kutanga, tanga washanda nekumhanya-mhanya pasina-mutoro kwe3 ~ 5 maminetsi, uye zvishoma nezvishoma uchinje kune yakakwirira-kumhanya kana inorema basa remutoro.

e.Inorambidzwa kushandisa jenareta dizeli kwenguva yakareba pasi pekuremerwa kudzivirira kukurumidza kukurumidza;Kana zvikaonekwa kuti mwenje wemafuta ekumanikidza mwenje wakabatidzwa, tsvaga chikonzero uye wochibata nemazvo usati waenderera mberi nekushanda.

f.Panguva yekugadzirisa, teerera kutarisa zvikamu zvose zve lubrication system.Zvikamu zvakakosha hazvigone kutsiviwa (semuenzaniso waya yesimbi haigoni kutsiva pini yecotter, nezvimwewo).Pakuunganidza, shandisa mafuta ekuzora akachena.

g.Paunenge uchitsiva gwenzi idzva rekubereka, tarisa kureba kwegwenzi rinotakura.Gwenzi rinotakura rakanyanya kupfupika kuti ive nechokwadi chekuenderana kwayo nejenari uye yakanaka kupisa kupisa;Kana gwenzi rinotakura rakareba, iyo interface ichave yakaremara, izvo zvinozotungamira kune shaft gnawing.

h.Gara uchitarisa kutonhora kweinjini yedhiziri yekutonhodza sisitimu, teerera kuwedzera iyo inotonhorera uye simbisa kana kutsiva bhandi re fan munguva kuti uve nechokwadi chekuti inotonhora inogara iri mumamiriro akanaka.
