1. Kushanda musimboti
Tubhini yemvura isimba rekuyerera kwemvura.Tubhini yemvura ndiyo muchina wemagetsi unoshandura simba rekuyerera kwemvura kuita rinotenderera remagetsi simba.Mvura iri mudura repamusoro pemvura inotungamirwa kuenda kuturbine kuburikidza nepombi yekuchinjisa, iyo inotyaira mumhanyi weturbine kutenderera uye inotyaira jenareta kugadzira magetsi.
Iyo yekuverengera fomula yeturbine yekubuda simba ndeyekutevera:
P＝9.H - musoro wemvura, m;Q - kuyerera kuburikidza ne turbine, m3 / S;η- Kushanda kwe hydraulic turbine
Iyo yakakwirira yemusoro h uye yakakura yekubuda Q, iyo yakakwirira kushanda kweiyo turbine η Iyo yakakwirira simba, iyo yakakura yekubuda simba.
2. Classification uye inoshanda musoro wemvura turbine
Turbine classification
Reaction turbine: Francis, axial kuyerera, oblique kuyerera uye tubular turbine
Pelton turbine: Pelton turbine, oblique stroke turbine, double stroke turbine uye Pelton turbine
Vertical yakasanganiswa kuyerera
Vertical axial kuyerera
Oblique kuyerera
Musoro unoshanda
Reaction turbine:
Francis turbine 20-700m
Axial flow turbine 3 ～ 80m
Increned flow turbine 25 ～ 200m
Tubular turbine 1 ～ 25m
Impulse turbine:
Pelton turbine 300-1700m (huru), 40-250m (diki)
20 ～ 300m ye oblique impact turbine
Tinya kaviri turbine 5 ～ 100m (diki)
Mhando ye turbine inosarudzwa maererano nemusoro wekushanda uye zvakananga kumhanya
3. Basic working parameters ye hydraulic turbine
Iyo inonyanya kusanganisira musoro h, kuyerera Q, kubuda P uye kushanda zvakanaka η, Speed n.
Hunhu H:
Maximum head Hmax: iyo yakanyanya mambure musoro iyo turbine inobvumirwa kushanda.
Minimum head Hmin: iyo shoma net musoro wekuchengetedza uye kugadzikana kushanda kwehydraulic turbine.
Weighted average head ha: huremu hweavhareji kukosha kwese misoro yemvura yeturbine.
Yakatemerwa musoro HR: iyo shoma net musoro unodiwa kuti turbine ibudise yakayerwa kubuda.
Discharge Q: vhoriyamu inoyerera ichipfuura nepakati yakapihwa kuyerera chikamu cheiyo turbine munguva yeyuniti, inowanzoshandiswa unit is m3 / s.
Kumhanyisa n: nhamba yekutenderera kweiyo turbine mumhanyi munguva yeyuniti, inowanzoshandiswa muR / min.
Kubuda P: simba rekubuda returbine shaft end, inowanzoshandiswa unit: kW.
kushanda zvakanaka
4. Chimiro chikuru cheturbine
Iwo makuru ezvimiro zveanoita turbine ari volute, gara ring, gidhigini, chivharo chepamusoro, mumhanyi, main shaft, giredhi rinotakura, mhete yepasi, dhizaini chubhu, nezvimwewo. Mifananidzo iri pamusoro inoratidza maumbirwo makuru eiyo turbine.
5. Factory test ye hydraulic turbine
Tarisa, shandisa uye edza zvikamu zvikuru senge volute, mumhanyi, main shaft, servomotor, dhiraivha inotakura uye yepamusoro chivharo.
Kuongorora kukuru uye bvunzo zvinhu:
1) Kuongorora kwezvinhu;
2) Welding kuongorora;
3) Kuedza kusina kuparadza;
4) Kuedzwa kwemanikidziro;
5) Dimension cheki;
6) Musangano wefekitari;
7) Movement test;
8) Runner static chiyero bvunzo, nezvimwe.
