Ishaft ye ityala lokwahlula impompo yinxalenye ebaluleke kakhulu, kwaye i-impeller ijikeleza ngesantya esiphezulu ngemoto kunye nokudibanisa. Ulwelo oluphakathi kwamagqabi lutyhalwa ngamagqabi, kwaye luphoswa ngokuqhubekayo ukusuka ngaphakathi ukuya kwi-periphery phantsi kwesenzo samandla e-centrifugal. Ummandla woxinzelelo oluphantsi lwenziwa xa i-liquid kwipompo iphonswa ukusuka kwi-impeller ukuya kumda. Ngenxa yokuba uxinzelelo lolwelo phambi kokungena kwimpompo likhulu kunoxinzelelo lwezibuko lokufunxa lwempompo, indawo apho umahluko woxinzelelo ukhutshwa kulwelo, ulwahlulo. impompo yetyala kufuneka icwangciswe rhoqo ngokuhambelana namava olawulo kunye nemeko yezixhobo zesixhobo sokuvelisa, kwaye ukugcinwa kufuneka kuqhutywe ngokwesicwangciso.

1. Ra=1.6um kumphezulu wehlathi.

2. I-shaft kunye ne-bushing yi-H7/h6.

3. Umphezulu we-shaft ulungile, ngaphandle kokuqhekeka, ukugqoka, njl.

4. Iphutha le-parallelism phakathi komgca ophakathi wendlela engundoqo yempompo ye-centrifugal kunye ne-centrifugal ye-shaft kufuneka ibe ngaphantsi kwe-0.03 mm.

5. Ukugoba okuvumelekileyo kobubanzi be-shaft akukho ngaphezu kwe-0.013mm, inxalenye ephakathi ye-shaft ye-low-speed pump shaft ayikho ngaphezu kwe-0.07mm, kwaye inxalenye ephakathi ye-high-speed pump shaft ayikho ngaphezu kwe-0.04mm. .

6. Coca kwaye ujonge i-shaft yempompo yepompo yokuvula kabini ephakathi. I-shaft yepompo kufuneka ingabi naziphene ezifana nokuqhekeka kunye nokugqoka okunzulu. Kukho ukunxiba, ukuqhekeka, ukukhukuliseka, njl., ekufuneka zirekhodwe ngokweenkcukacha, kwaye izizathu kufuneka zihlalutywe.

7. Ukunyaniseka kwe-shaft yepompo yeoli ye-centrifugal akufanele idlule i-0.05 mm ngaphezu kobude bonke. Umphezulu wejenali awuyi kuba nemingxuma, iigrooves kunye nezinye iziphene. Ixabiso lobunzima bomphezulu ngu-0.8μm, kwaye ukujikeleza kunye neempazamo ze-cylindricity zejenali kufuneka zibe ngaphantsi kwe-0.02mm.
