1. Pombi shaft simba calculation formula

Mwero wekuyerera × musoro × 9.81 × epakati nepakati giravhiti ÷ 3600 ÷ pombi kushanda zvakanaka

Flow unit: cubic/awa,

Lift unit: mamita

P=2.73HQ/η,

Pakati pavo, H ndiye musoro mu m, Q chiyero chekuyerera mu m3/h, uye η ndiko kugona kweyakadzika zvakanaka vertical turbine pombi. P ndiyo shaft simba muKW. Kureva kuti, shaft simba repombi P=ρgQH/1000η(kw), apo ρ =1000Kg/m3,g=9.8

Chiyero chegiravhiti chaiyo iKg/m3, chikamu chekuyerera m3/h, chikamu chemusoro m, 1Kg=9.8 Newtons

Zvadaro P=specific gravity*kuyerera*musoro*9.8 Newton/Kg

=Kg/m3*m3/h*m*9.8 Newton/Kg

=9.8 Newton*m/3600 masekondi

=Newton*m/367 masekondi

=Watts/367

Kubva pamusoro apa ndiko kwakabva chikwata. Formula iri pamusoro ndiyo kuverenga kwesimba remvura. Simba re shaft rinoparadzaniswa nekushanda.

Ngatitii shaft simba ndiNe, iyo mota simba iP, uye K ndiyo coefficient (kudzoreredza kwekushanda)

Motokari simba P=Ne*K (K ine hunhu hwakasiyana kana Ne yakasiyana, ona tafura iri pazasi)

Ne≤22 K=1.25

2. Calculation formula ye slurry pombi shaft simba

Flow rate Q M3/H

Simudza H m H2O

Efficiency n%

Slurry density A KG/M3

Shaft simba N KW

N=H*Q*A*g/(n*3600)

Motokari magetsi inodawo kufunga nezve kutapurirana zvakanaka uye kuchengetedza chinhu. Kazhinji, kuwirirana kwakananga kunotorwa se 1, bhanhire rinotorwa se 0.96, uye kuchengetedza chinhu 1.2.

3. Kushanda Kwepombi uye Kuverengera kwayo Formula

Zvinoreva chiyero chesimba rinoshanda re yakadzika zvakanaka vertical turbine pombi kune simba re shaft. η=Pe/P

Simba repombi rinowanzo reva simba rekupinza, kureva kuti, simba rinofambiswa kubva kune yekutanga mover kuenda kune pombi shaft, saka inonziwo shaft simba uye inomiririrwa naP.

Simba rinoshanda ndere: chigadzirwa chemusoro wepombi, huwandu hwekuyerera uye kukurumidza kwegiravhiti.

Pe=ρg QH (W) kana Pe=γQH/1000 (KW)

ρ: Kuwanda kwemvura inotakurwa nepombi (kg/m3)

γ: Kurema kwemvura inotakurwa nepombi γ=ρg (N/m3)

g: kukurumidza nekuda kwegiravhiti (m/s)

Kuyerera kwehuwandu Qm=ρQ (t/h kana kg/s)

4. Nhanganyaya yeKushanda Kwemapombi

Chii chinonzi pombi kushanda zvakanaka? Formula yacho chii?

Mhinduro: Inoreva chiyero chesimba rinoshanda repombi kune simba re shaft. η=Pe/P

Simba retsime rakadzika vertical turbine pombi kazhinji inoreva simba rekuisa, kureva kuti, simba rinofambiswa kubva kune yekutanga mover kuenda kune pombi shaft, saka inonziwo shaft simba uye inomiririrwa naP.

Simba rinoshanda ndere: chigadzirwa chemusoro wepombi, huwandu hwekuyerera uye kukurumidza kwegiravhiti.

Pe=ρg QH W kana Pe=γQH/1000 (KW)

ρ: Kuwanda kwemvura inotakurwa nepombi (kg/m3)

γ: Kurema kwemvura inotakurwa nepombi γ=ρg (N/m3)

g: kukurumidza nekuda kwegiravhiti (m/s)

Kuyerera kwakawanda Qm=ρQ t/h kana kg/s
