Prema pronalasku je namenjena za transport čvrstih, tečnih i gasovitih materijala posredstvom nekog fluida (voda, vazduh). Pumpa se sastoji od dovodnog cevovoda (1), unutrašnjeg mlaznika (2), cevovoda (3) za dovod čistog fluida, unutrašnje komore (4) za mešanje, kanala (5) za napajanje svežim materijalom, spoljnjeg mlaznika (6), spoljašnje komore (7) za mešanje komore (8), difuzora (9) i transportnog cevovoda (10). Čist fluid ulazi u unutrašnji mlaznik (2) iz. cevovoda (3) za napajanje čistim fluidom i iz mlaznika ističe velikom brzinom. Mlaz zahvata materijal koji ulazi u unutrašnju komoru (4) za mešanje kroz kanal (5), mesa se sa njim i predaje mu energiju i mešavina velikom brzinom isuče iz spoljašnjeg mlaznika (6) u spoljašnju komoru (7) za mešanje gde se meša sa mešavinom koja cevovodom (1) dolazi do spoljašnje komore (7) za mešanje. Tu se predaje energija mešavini i nakon prolaska elementa (8) i smirivanja u difuzoru (9), mešavina se transportuje cevovodom (10) ka potrošaču ili drugoj mlaznoj pumpi.Otvaranje - zatvaranje unutrašnjeg mlaznika (2) i kanala za napajanje materijalom koji se transportuje ostvaruje se varačem (11), koji je oslonjen na ležajeve (12) koji su od prevelikog habanja zaštićeni čaurama (13) sa raspršivačima. Zatvarač (11) je pogonjen zaokretaim motorom (15) preko reduktora (16). Pogonski fluid za motor je fluid koji se koristi za napajanje mlaznika.Mlazna pumpa se veoma uspešno može koristiti za transport čvrstih, tečnih i gasovitih materijala u rudarstvu, hemijskoj, procesnoj i prehrambenoj industriji.According to the invention, it is intended for the transport of solid, liquid and gaseous materials via a fluid (water, air). The pump consists of a supply pipeline (1), an internal jet (2), a pipeline (3) for the supply of pure fluid, an internal mixing chamber (4), channels (5) for supplying fresh material, an external jet (6), an external chamber (7) for mixing chamber (8), diffuser (9) and conduit (10). Pure fluid enters the inner jet (2) from. pipeline (3) to supply clean fluid to and from the nozzle at high speed. The jet enters the material that enters the inner chamber (4) for mixing through the channel (5), fuses with it and transfers energy to it, and the mixture is pumped at high speed from the outer jet (6) into the outer mixing chamber (7) where it is mixed with with the mixture, which leads to the outer mixing chamber (7) by pipeline (1). This is where the energy is transferred to the mixture and after passing the element (8) and settling down in the diffuser (9), the mixture is transported by pipeline (10) to the consumer or another jet pump. is achieved by a welder (11), which is supported by bearings (12) which are protected from excessive wear by bushes (13) with sprays. The shutter (11) is driven by a rotary motor (15) via a gearbox (16). Engine fluid is a fluid used to power a jet. A jet pump can be used very successfully to transport solid, liquid, and gaseous materials in the mining, chemical, process, and food industries.
