I-shaft ye- icala lokuhlukanisa iphampu iyingxenye ebaluleke kakhulu, futhi i-impeller ijikeleza ngesivinini esikhulu ngokusebenzisa i-motor kanye nokuhlanganisa. Uketshezi oluphakathi kwama-blades luphushwa ama-blades, futhi luphonswa ngokuqhubekayo kusukela ngaphakathi kuya ku-periphery ngaphansi kwesenzo samandla we-centrifugal. Indawo yokucindezela ephansi yenziwa lapho uketshezi olusepompo luphonswa kusukela ku-impeller kuya onqenqemeni. Ngenxa yokuthi ingcindezi yoketshezi ngaphambi kokungena epompo inkulu kunokucindezela kwembobo yokudonsa yephampu, indawo lapho umehluko wengcindezi ukhishwa khona oketshezini, ukuhlukana phakathi. iphampu yecala kufanele kuhlelwe njalo ngokuya ngesipiliyoni sokuphatha kanye nesimo semishini yempahla yokukhiqiza, futhi ukunakekelwa kufanele kwenziwe ngokohlelo.

1. Ra=1.6um phezu kwesihlahla.

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

3. I-shaft surface ibushelelezi, ngaphandle kokuqhekeka, ukuguga, njll.

4. Iphutha lokufana phakathi komugqa omaphakathi wokhiye wephampu emaphakathi nendawo emaphakathi ye-shaft kufanele ibe ngaphansi kuka-0.03 mm.

5. Ukugoba okuvunyelwe kobubanzi be-shaft akukho ngaphezu kwe-0.013mm, ingxenye ephakathi ye-shaft ye-low-speed fuft ayikho ngaphezu kuka-0.07mm, futhi ingxenye ephakathi ye-high-speed pump shaft ayikho ngaphezu kuka-0.04mm. .

6. Hlanza futhi uhlole i-pump shaft yepompo edonsa kabili phakathi nokuvula. I-pump shaft kufanele ingabi namaphutha njengokuqhekeka nokuguga okukhulu. Kukhona ukugqoka, ukuqhekeka, ukuguguleka, njll, okufanele kubhalwe ngokuningiliziwe, futhi izizathu kufanele zihlaziywe.

7. Ukuqondisa kwe-shaft yepompo yamafutha e-centrifugal akufanele kudlule u-0.05 mm ngaphezu kobude bonke. Indawo yejenali ngeke ingabi nemigodi, imifantu nokunye ukonakala. Ivelu yobulukhuni bendawo ngu-0.8μm, futhi amaphutha ayindilinga nesilinda wejenali kufanele abe ngaphansi kuka-0.02mm.
