Umgangatho oPhezulu weDizili yokuTofa iPump BH4PN120R Amacandelo eNjini ye-WEICHAI TD226B-4

Njengenxalenye ephambili ye-friction yepompo yegesi yamafutha, iimpawu zokuthwala zinempembelelo ebalulekileyo ekusebenzeni okusebenzayo, ukuthembeka kunye nobomi bompompo wamafutha. Impompo ye-fuel yokuhambisa i-fuel ye-viscosity fuel ephantsi, kumthwalo ophezulu kunye neemeko zesantya esiphezulu, ubuncinci befilimu ye-oyile yobunzima be-sliding bearing incinci kakhulu, ngokusisiseko i-oda efanayo yobukhulu kunye noburhabaxa bomphezulu bamacandelo, kulula ukunxiba kunye nokukrazula. kwaye ngaloo ndlela kukhokelela ekungaphumeleli kwe-fuel pump sliding bearing. Kwi-lubricating medium viscosity kunye nomthwalo wemeko ethile, ukutyibilika ukuthwala imvume yokulinganisa (ibhekisa kwicala le-sliding bearing kunye ne-shaft diameter clearance kunye ne-shaft diameter ratio) yeyona mpembelelo iphambili yobukhulu befilimu obuncinci, ethi yona ichaphazele ukuthwala. umthamo.

Ke ngoko, ukuze kulungiswe ingxaki yokuba iibheringi ezityibilikayo zeempompo zegiya lamafutha ziqhele ukunxiba ngenxa yobunzima befilimu yeoli ebhityileyo, nto leyo ekhokelela ekungaphumelelini kweebheringi zokutyibilika phantsi komthwalo ophakamileyo kunye neemeko zesantya esiphezulu, kwaye ngokujonga Inyaniso yokuba umlinganiselo wokucocwa yeyona nto iphambili enempembelelo yobuninzi befilimu yeoli yeebheringi ezityibilikayo, iibheringi ezityibilikayo zohlobo oluthile lweempompo zamafutha zithathwa njengento yophando ekufuneka ifundwe kwaye ihlalutywe ngokulinganisa kwePumpLinx ukumisela ubuncinci befilimu yeoli yobunzima beebheringi, umthamo wokuthwala umthwalo, uxinzelelo kunye nokusabalalisa ubushushu beebheringi ezinemilinganiselo eyahlukeneyo yokucocwa. Ubuncinci befilimu yeoli, umthamo womthwalo, uxinzelelo kunye nokuhanjiswa kweqondo lokushisa kweebheringi kunye nemilinganiselo eyahlukeneyo yokucoca ihlalutywa yiPumpLinx simulation. I-Flexural deformation ye-gear shaft yempompo ethile yamafutha iyahlaziywa, kwaye ke ubudlelwane phakathi kwe-sliding bearing clearance ratio kunye nobukhulu befilimu yeoli, umthamo womthwalo, ubushushu obuthweleyo kunye nokuhanjiswa koxinzelelo lwe-circumferential kunye ne-radial kuhlalutywa phantsi kweemeko ezimbini zokusebenza. , oko kukuthi, isantya esincinci kunye nesantya esiphezulu sempompo, ngokulandelanayo. Iziphumo zibonisa ukuba: kwi-fit clearance ratio efanayo, umthamo we-sliding bearing uyanda xa ubukhulu befilimu yeoli buyancipha; xa umlinganiselo wokuhlanjululwa uyancipha, umthamo wokuthwala uyanda; xa isantya sanda, amandla okuthwala ayanda; ngokubhekiselele kokubini ukusabalalisa koxinzelelo kunye nokunyuka kweqondo lokushisa, imeko engcono kakhulu ifunyenwe xa umlinganiselo wokucoceka ofanelekileyo we-gear shaft kunye ne-sliding bear iyona encinci.
