1. Tiza BEP:

Kushanda kunze kwenzvimbo yeBEP ndiyo inonyanya kukonzera kutadza kwepombi shaft. Kushanda kure neBEP kunogona kuburitsa yakawandisa radial masimba. Shaft deflection nekuda kwemasimba eradial inogadzira masimba ekukotama, izvo zvichaitika kaviri pombi shaft kutenderera. Kukotama uku kunogona kuburitsa kuneta kwekukotama kweshaft. Mazhinji epombi shafts anogona kubata nhamba huru yematenderedzwa kana hukuru hwekutsauka hwakaderera zvakakwana.

2. Bent pombi shaft:

Dambudziko rakakombama axis rinotevera pfungwa imwechete seyakatsauka axis inotsanangurwa pamusoro. Tenga pombi uye shafts yekusara kubva kune vanogadzira zvemhando yepamusoro/specs. Mazhinji ekushivirira pamapombi shaft ari mu 0.001 kusvika 0.002 inch renji.

3. Unbalanced impeller kana rotor:

Iyo isina kuenzana impeller inoburitsa "shaft churning" kana ichishanda. Mhedzisiro yacho yakafanana nekukotama shaft uye / kana kutsauka, uye pombi shaft ye yakadzika zvakanaka vertical turbine pombi ichazadzisa zvinodiwa kunyange kana pombi yakamiswa kuti iongororwe. Zvinogona kutaurwa kuti kuenzanisa iyo impeller yakakosha kune yakaderera-speed pombi seyakakwirira-speed pombi.

4. Fluid properties:

Kazhinji mibvunzo pamusoro pezvimiro zvemvura inosanganisira kugadzira pombi yemvura yakaderera ye viscosity asi kuti imirire yakakwira viscosity fluid. Muenzaniso wakapfava ungave pombi yakasarudzwa kupomba No. 4 mafuta emafuta pa 35 ° C uye yozoshandiswa kupomba mafuta emafuta pa 0 ° C (inenge musiyano i235Cst). Kuwedzera kwesimba rinokwevera remvura inopomba kunogona kukonzera matambudziko akafanana.

Uyewo cherechedza kuti kuora kunogona kuderedza zvakanyanya simba rekuneta kwepombi shaft material.

5. Variable speed operation:

Torque uye kumhanya zvakaenzana. Sezvo pombi inononoka, iyo pombi shaft torque inowedzera. Semuenzaniso, pombi ye100 hp inoda torque yakapetwa kaviri pa875 rpm sepombi ye100 hp iri 1,750 rpm. Pamusoro peiyo yakanyanya brake horsepower (BHP) muganho weshaft yese, mushandisi anofanirawo kutarisa inobvumidzwa BHP muganho pazana rpm shanduko mukupombi application.

6. Kusashandisa Zvisizvo: Kuregeredza nhungamiro yemugadziri kunotungamirira kumatambudziko epombi shaft.

Mazhinji epombi shafts ane derating zvikonzero kana pombi inotyairwa neinjini kwete yemagetsi mota kana turbine yehutsi nekuda kwe intermittent vs. inoenderera torque.

kana yakadzika zvakanaka vertical turbine pombi haisi kufambiswa zvakananga kuburikidza nekubatanidza, semuenzaniso bhandi / pulley, cheni / sprocket drive, pombi shaft inogona kuderedzwa zvakanyanya.

Mapombi akawanda ega-priming akagadzirwa kuti afambiswe nebhandi uye nekudaro ane mashoma ematambudziko ari pamusoro. Zvisinei, zvakadzika zvakanaka vertical turbine pombi yakagadzirwa maererano ne ANSI B73.1 zvinyorwa hazvina kugadzirwa kuti bhandi rinotyairwa. Kana bhandi rinotyairwa richishandiswa, iyo yakanyanya kubvumidzwa simba rebhiza ichaderedzwa zvakanyanya.

7. Kusarongeka:

Kunyangwe kushomeka kushoma pakati pepombi nemidziyo yekutyaira kunogona kukonzera nguva dzekukotama. Kazhinji, dambudziko iri rinozviratidza sekutadza kubereka pamberi pepombi shaft yaputsika.

8. Vibration:

Kuzununguka kunokonzerwa nezvinetso kunze kwekukanganisa uye kusaenzana (semuenzaniso, cavitation, passing blade frequency, etc.) zvinogona kukonzera kushushikana pane pombi shaft.

9. Kuiswa zvisirizvo kwezvikamu:

Semuenzaniso, kana iyo impeller uye coupling isina kuisirwa nenzira kwayo pane shaft, iyo isiriyo kukwana inogona kukonzera kukwira. Kupfeka zvinokambaira kunogona kukonzera kuneta kukundikana.

10. Kumhanya kusina kunaka:

Iyo yakakura yekumhanya yepombi yakavakirwa pane impeller inertia uye (peripheral) yekumhanyisa muganho webhandi drive. Uyezve, mukuwedzera kune nyaya yekuwedzera torque, panewo kufunga nezve yakaderera-kumhanya kushanda, senge: kurasikirwa kwemvura inoderedza mhedzisiro (Lomakin effect).
