Iyo shaft ye split case pombi chikamu chakakosha, uye impeller inotenderera nekumhanya kukuru kuburikidza nemota uye kubatana. Mvura iri pakati pemashizha inosundirwa nemashizha, uye inoramba ichikandwa kubva mukati kusvika kune imwe nzvimbo pasi pechiito che centrifugal force. Nzvimbo yakaderera yekumanikidza inoumbwa apo mvura iri mupombi inokandwa kubva kune impeller kusvika kumucheto. Nekuti dzvinyiriro yemvura isati yapinda pombi yakakura kupfuura kudzvanywa kwechiteshi chekukweva chepombi, iyo nzvimbo iyo musiyano wekumanikidza unoburitswa kubva mumvura, kupatsanurwa. pombi yemhosva inofanirwa kugara yakarongwa maererano neruzivo rwekutungamira uye mamiriro emidziyo yemidziyo yekugadzira, uye kuchengetedza kunofanirwa kuitwa zvinoenderana nehurongwa.

1. Ra=1.6um pamusoro pegwenzi.

2. Iyo shaft uye bushing ndeye H7 / h6.

3. Iyo shaft yepamusoro yakatsetseka, isina kuputika, kupfeka, nezvimwe.

4. Kukanganisa kweparallelism pakati pepakati pekiyi yepombi ye centrifugal uye yepakati ye shaft inofanira kuva isingasviki 0.03 mm.

5. Kukotama kunobvumirwa kweshaft dhayamita hakusi kupfuura 0.013mm, chikamu chepakati chepasi-speed pombi shaft haisi kupfuura 0.07mm, uye chikamu chepakati chepamusoro-speed pump shaft haisi kupfuura 0.04mm. .

6. Chenesa uye chengetedza pombi yepombi yepombi-suction yepakati yekuvhura pombi. Iyo pombi shaft inofanirwa kunge isina hurema hwakaita sekutsemuka nekupfeka kwakakomba. Pane kupfeka, kuputika, kuputika, nezvimwewo, izvo zvinofanira kunyorwa zvakadzama, uye zvikonzero zvinofanira kuongororwa.

7. Kururama kweshaft yepombi yemafuta yecentrifugal haifaniri kudarika 0.05 mm pamusoro pehurefu hwose. Iyo jenari yepamusoro haizove isina makomba, migodhi uye kumwe kukanganisa. Iko kukosha kweiyo roughness yepasi ndeye 0.8μm, uye kutenderera uye cylindricity kukanganisa kwejenari kunofanirwa kunge kuri pasi pe0.02mm.
