Ngoba ukusetshenziswa kwephampu yeSlurry kukhulu kakhulu, uhlobo loketshezi ludluliswa kwesinye isikhathi luwumehluko omkhulu, izimo ezahlukahlukene zomsebenzi zinezidingo ezihlukile zokugeleza kwephampu ezindaweni ezahlukahlukene , kunezinhlobo eziningi zepompo, imvamisa zingahlukaniswa ngokuya ngomgomo wokusebenza wepompo, futhi ukusetshenziswa kwawo kungakunikeza ukuphakamisa. Ngokusho komgomo wokusebenza kwephampu kungahlukaniswa ngephampu elihle lokufuduka, iphampu ye-vane kanye nezinye izinhlobo zamaphampu amathathu
Amaphampu wokufuduka ancike ekushintsheni kwevolumu ngezikhathi ezithile ukuncela kwevolumu nokukhipha, lapho ivolumu yomsebenzi ikhuphuka, i-Pumps Suction Liquid; lapho kwehla, uketshezi lwepompo. Izici ze-kinematic ngokuya ngomsebenzi walolu hlobo uLi ngokwahlukana kwehlukaniswe:
1. Ukubuyisela inqubo yokusebenza kwempompo yokubuyisela ukunyakaza. Lolu hlobo lwephampu luyiphampu yePiston, i-piston, i-diaphragm chestnut nokunye.
Ama-Ejensi Wokusebenza Kwemisebenzi engu-2.Rands Pumps yokujikeleza kwe-axis. Lolu hlobo lwephampu luyiphampu yegiya, pump screw,imboni yamapompo yamatshe amatsheukuslayida amaphampu we-vane.
I-Vane Chestnut incike ukujikeleza okuphezulu noma okuningana okusheshayo kwe-impeller ukukhuthaza ukuhamba uketshezi, ukufezekisa ukuthuthwa koketshezi. Ngokusho koketshezi ekuqondisweni kokugeleza kwephampu yepompo ye-pump vane nakho kuhlukaniswe:
I-1.Pump Fluid igeleza kakhulu ngephampu, amandla acindezela ukugeleza koketshezi lapho ama-centrifugal Force akhiqizwa ngokujikeleza kwe-impeller.

3
4 - I-Vortex Pump Liquid ephampu yokugeleza okuqondile kwe-vortex, ukuthembela kumthengisi ojikelezayo ukukhuthaza izihambi ezikhiqizwe ukunyakaza koketshezi noketshezi.
Ezinye izinhlobo zamaphampu zincike kakhulu kolunye uketshezi (uketshezi, igesi) amandla noma uketshezi lwe-kinetic Energy hydrostatic truddrostatic trud. Ngakho-ke, ebizwa nangokuthi iphampu yeHydrodynamic, efana namaphampu we-jet, isifuba samanzi, njll. Hammer.
Amapharamitha ayisisekelo ezakhiwo eziphambili zepompo yamatshe amatshe alandelayo:
1, ukugeleza kwe-q
Ukugeleza inani le-liquid gravel Pump ekulethweni kwesikhathi seyunithi (ivolumu noma ikhwalithi).
Ukugeleza kwevolumu nge-Q kusho, iyunithi yile: m3 / s, m3 / h, l / s njll ..
Ukugeleza okuningi nge-QM kusho, iyunithi yi: T / H, kg / s.
Ubudlelwano phakathi kokugeleza okuningi nokugeleza kwevolumu:
Qm = ρ y
Ku-formula ncy density (kg / m3, t / m3), amazinga okushisa ajwayelekile p = 1000kg / m3.
2, inhloko ye-h
Ikhanda isisindo seyunithi se-liquid gravel pump pow engeniswa kusuka kuphampu ye-gravel (i-inlet flange gravel Pump) kuya ku-gravel endaweni ephumayo yepompo (ipompo outlet flange gravel) ukukhuphuka kwamandla. Amandla asebenzayo yi-newtonia uketshezi etholwe yi-gravel Pump. Iyunithi yi-n? m / n = m, ukuphakama kwe-liquid colovel pump pump uketshezi, imikhuba, okubizwa ngokuthi nguM.
3, ijubane n
Ijubane liyijubane le-gravel pump shaft unit wesikhathi, esiboniswe uphawu n, iyunithi le-R / min.
4, NPSH NPSH
I-NPSH ibizwa nangokuthi yiNhloko ye-Net Polight Suction, ivezwa ikakhulukazi amapharamitha wokusebenza kwe-cavitation. I-NPSH ekusetshenzisweni kwasekhaya δ H.
kg / m3);
5, amandla nokusebenza kahleIsisekelo sokukhetha se-Slurry Pump
Amandla wepompo wama-gravel avame ukubhekisela emandleni okufaka, okuyisisusa sokuqala kwafika amatshe amaphampu shash shaft, ngakho-ke kubizwa ngokuthi amandla shaft, amelela ngo-p;
Iphampu yamandla e-Power Pump esebenzayo ibizwa nangokuthi amandla okukhipha, amele yi-PE. Kuyinto esebenzayo yamandla iyunithi yesikhathi kusuka ekulethweni kwepompo yamatshe amatshe aphuma ku-ketshezi ephampu yamatshe.
Ngoba i-lift yiyunithi yokukhipha amandla ye-Energy Gravel Pump etholwe ku-pump yamatshe, ngakho-ke ikhanda kanye nokushesha kwamanzi adonsela phansi, kungukusebenza kwepompo yamatshe amatshe alandelayo Amandla:
PE =
I-gamma ebabazekayo - i-gravel Pump Liquid (N / M3);
Q - Flow Flow Flow (M3 / S);
H - Ikhanda lamaphampu we-gravel (m);
G - ukushesha kwamandla adonsela phansi (M / S2).
I-SHAFT Power P kanye namandla okulahleka kwamandla kwepompo yamatshe amatshe, ubukhulu be-gravel Pump Ukusebenza Kanye. Ukusebenza kwepompo yama-gravel njenge-Power Power neShaft Power Ratio, kusetshenziswa i-η.
