1. Njira yowerengera mphamvu ya shaft pampu

Mtengo woyenda × mutu × 9.81 × mphamvu yokoka yapakatikati ÷ 3600 ÷ pampu yogwira ntchito

Gawo loyenda: kiyubiki / ola,

Lift unit: mita

P=2.73HQ/η,

Pakati pawo, H ndiye mutu mu m, Q ndi kuthamanga kwa m3/h, ndipo η ndikokwanira kwapampu yakuya ya turbine yakuya bwino. P ndiye mphamvu ya shaft mu KW. Ndiko kuti, mphamvu ya shaft ya mpope P=ρgQH/1000η(kw), pamene ρ =1000Kg/m3,g=9.8

Gawo la mphamvu yokoka yeniyeni ndi Kg/m3, gawo la kuyenda ndi m3/h, gawo la mutu ndi m, 1Kg=9.8 Newtons

Kenako P=mphamvu yokoka* yeniyeni*kutuluka*mutu*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

Zomwe zili pamwambazi ndi chiyambi cha unit. Njira yomwe ili pamwambayi ndikuwerengera mphamvu yamadzi. Mphamvu ya shaft imagawidwa ndi mphamvu.

Tiyerekeze mphamvu ya shaft ndi Ne, mphamvu yagalimoto ndi P, ndipo K ndiye coefficient (kufanana kwa magwiridwe antchito)

Mphamvu yamagalimoto P=Ne*K (K ili ndi mikhalidwe yosiyana pamene Ne ndi yosiyana, onani tebulo ili m'munsimu)

Ne≤22 K=1.25

2. Kuwerengera mphamvu ya slurry pump shaft power

Mayendedwe a Q M3/H

Kwezani H m H2O

Kuchita bwino n%

Kuchuluka kwa Slurry A KG/M3

Shaft mphamvu N KW

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

Mphamvu zamagalimoto zimafunikanso kuganizira za kufalitsa bwino komanso chitetezo. Nthawi zambiri, kulumikizana mwachindunji kumatengedwa ngati 1, lamba amatengedwa ngati 0.96, ndipo chitetezo ndi 1.2.

3. Pampu Mwachangu ndi Mawerengeredwe Formula

Amatanthauza chiŵerengero cha mphamvu ya mphamvu ya pampu yakuya ya turbine yakuya bwino ku mphamvu ya shaft. η=Pe/P

Mphamvu ya mpope nthawi zambiri imatanthawuza mphamvu yolowera, ndiko kuti, mphamvu yomwe imaperekedwa kuchokera kwa prime mover kupita ku shaft shaft, motero imatchedwanso mphamvu ya shaft ndipo imayimiridwa ndi P.

Mphamvu yogwira ntchito ndi: chopangidwa ndi mutu wa mpope, kuthamanga kwa misa ndi kuthamanga kwamphamvu yokoka.

Pe=ρg QH (W) kapena Pe=γQH/1000 (KW)

ρ: Kachulukidwe wamadzimadzi otumizidwa ndi mpope (kg/m3)

γ: Mphamvu yokoka yamadzi yotengedwa ndi mpope γ=ρg (N/m3)

g: kuthamanga chifukwa cha mphamvu yokoka (m/s)

Kuthamanga kwakukulu Qm=ρQ (t/h kapena kg/s)

4. Mawu Oyamba pa Kuchita Bwino Kwa Mapampu

Kodi mphamvu ya mpope ndi chiyani? Fomula yake ndi chiyani?

Yankho: Zimatanthawuza chiŵerengero cha mphamvu yabwino ya mpope ku mphamvu ya shaft. η=Pe/P

Mphamvu ya chitsime chakuya pampu yoyimirira ya turbine Nthawi zambiri amatanthauza mphamvu yolowera, ndiye kuti, mphamvu yochokera ku poyambira kupita ku shaft ya mpope, motero imatchedwanso mphamvu ya shaft ndipo imayimiridwa ndi P.

Mphamvu yogwira ntchito ndi: chopangidwa ndi mutu wa mpope, kuthamanga kwa misa ndi kuthamanga kwamphamvu yokoka.

Pe=ρg QH W or Pe=γQH/1000 (KW)

ρ: Kachulukidwe wamadzimadzi otumizidwa ndi mpope (kg/m3)

γ: Mphamvu yokoka yamadzi yotengedwa ndi mpope γ=ρg (N/m3)

g: kuthamanga chifukwa cha mphamvu yokoka (m/s)

Kuchuluka kwakuyenda Qm=ρQ t/h kapena kg/s
