Ukwahlulahlulwa ngokomgaqo wokuSebenza wePumpry Pump

Kuba ukusetyenziswa kwempompo ye-slurry kudluliselwa kakhulu, imeko yolwelo idluliselwa umahluko omkhulu, iimeko ezahlukeneyo zomsebenzi zineemfuno ezahlukeneyo zokuhamba kwempompo kunye nokuhlangabezana neemfuno zomsebenzi wempompo kwiindawo ezahlukeneyo , Zininzi iindidi zempompo, zihlala zinokuhlelwa ngokomgaqo wokusebenza wempompo, kwaye ukusetyenziswa kwayo kunokubonelela ngokuphakamisa. Ngokutsho komgaqo wokusebenzela wempompo unokwahlulahlulwa kwimpompo ye-pump yokufuduka, i-vane pump kunye nolunye uhlobo lweempompo ezintathu

I-pumpscescescescescescescescescescescescescescescescescentration Pumps ixhomekeke kwivolumu yotshintsho lwevolumu ezenziwe ngexesha lokunyanzelwa kwevolumu kunye nokukhupha amanzi, xa ivolumu yomsebenzi inyuka, i-Pump yoLwandle; Xa ihla, impompo ikhuphe ulwelo. Iimpawu ze-kinematic ngokwalo komsebenzi wohlobo lwe-LI on jikelele zahlulwe zaya:
I-1. Ukubuyisa impompo yokusebenza kwempompo yokufumana isindululo. Olu hlobo lwempompo yimpompo yepiston, ipiston, i-diaphragm chefnut njalo njalo.
Iiarhente zePumps zePumps zomsebenzi ze-Axis ezisisigxina. Olu hlobo lwempompo yimpompo yegiya, impompo ye-screw,I-Gralt PumpSUkutyibilika impompo ye-vane.

I-vane checnut rely enye okanye ukujikeleza okuphezulu okuphezulu kwe-impleller ukukhuthaza ukuhamba kwamanzi, ukufezekisa uthutho lwamanzi. Ngokutsho kolwelo kwindlela yokuhamba kwe-pump vane impompo yepompo yahlulahlulwe yaya:
I-1.Pump i-Famid ihamba kakuhle kwimpompo, amandla atyhala ulwelo lokuhamba kwamanzi xa amandla e-centrifugal aveliswe ngokujikeleza komzimba.
.
I-3. Ukuhamba kwamanzi kwi-pumps kwimpompo ukuya kwimpompo yempompo kwi-engile ethile, amandla atyhila i-centrifugal iveliswe ngumkhosi we-imples kunye nomkhosi we-axial.
I-4 - i-vrtix i-pump yolwelo kwimpompo yokuhamba kwe-vertex, ixhomekeke kumthengisi we-Imphote ijikeleza i-vortices eveliswe ngokuhamba kwesabelo kunye nokukhupha amanzi.

Ezinye iintlobo zempompo zixhomekeke ikakhulu kolunye ulwelo (ulwelo, igesi) amandla okanye i-kinetic hydrostatic fluid. Ke ngoko, ebizwa ngokuba yimpompo ye-hydrodynamic, ezinjengeempompo zejet, i-checknut yamanzi, njl. Njl.

Iiparamitha ezisisiseko zepropathi ephambili yempompo yegrabile inezi zinto zilandelayo:
1, ukuhamba kwe-q
Ukuhamba yimali yempompo yegravel yegraves kwiyunithi yokuhanjiswa kwexesha (ivolumu okanye umgangatho).
Ukuhamba kwevolumu nge-Q, iyunithi yile: m3 / s, m3 / h, l, l njl ..
Ukuhamba kwesininzi nge-QM uthe, iyunithi yile: t / h, kg / s.
Ubudlelwane phakathi kokuhamba kwesininzi kunye nokuhamba kwevolumu:
QM = ρ q
Kwifomula ρ-i-fluelity yoxinzelelo (kg / m3, i-t / m3), iqondo lobushushu eliqhelekileyo lamanzi p = 1000kg / m3.
2, Intloko ye-H
Intloko intloko yeyunithi yempompo yegrabile engeniswe impompo ingeniswe kwi-pump yempompo yegrabile (i-Inlet Flovel) kwigrabile ekuphumeni kwempompo) Amandla afanelekileyo ngulwelo olutsha olufunyenwe yimpompo yegrabile. Iyunithi i-n? m / n = m, ukuphakama kwekholamu ye-Gravel ye-Gravel Gravel Pump, imikhwa, ekubhekiswa kuyo njengeM.
I-3, isantya n
Isantya sesantya se-gump ye-gump ye-gump yexesha, ichazwa ngusimboli n, iyunithi ye-R / min.
4, NPSh NPSh
I-NPSH ikwabizwa ngokuba yintloko ye-net ye-net, ibonakaliswa ikakhulu imilinganiselo yokusebenza kwe-cavite. I-NPSH kwi-Fight δ h.
kg / m3);
5, amandla kunye nokusebenza kakuhleIsiseko sokukhetha impompo yelayita
I-Gralts Pump Rump idla ngokubhekisa kumandla okufaka, eyintshukumisa yantlandlolo yeza namandla e-pump yegrabile, ke ikwabizwa ngokuba yi-Shaft amandla, ifanekiswe ngu-Shaft, imele P;
Impompo yokusebenza esebenzayo ikwabizwa ngokuba ligunya lemveliso, limele i-PE. Yiyunithi yamandla esebenzayo yexesha ukusuka kwi-pump ye-pump ye-pump yokuphuma kolwelo kwimpompo yegrabile.
Kuba ukuphakamisa i-pump yolwelo olusebenzayo lwe-pumps ye-pump yolwelo olufunyenwe kwi-Gravel Pump, intloko kunye nenqanaba lokuhamba kwesininzi, yi-Gravel PumpOT Amandla:
I-PE = ρ gqh (w) = gamma q qh (W) ifomula ρ Ukuxinana - i-Gravel Pump yolwelo (kg / m3);
I-gammar gamma - igrabile ye-pump yolwelo (N / M3);
Q - I-Gralts Pump Pump (M3 / s);
H - intloko ye-Gravel Pump (M);
G - Ukukhawulezisa umxhuzulane (m / s2).
I-Shaft Power P kunye namandla Pemb Ilahleko yamandla eTravel Pump, ubungakanani be-Gravel Pump. Ukusebenza kakuhle kwegrabile njengomyinge wamandla asebenzayo kunye nomlinganiselo wamandla eshafti, usebenzisa η.
