Local experimental studies of the fertilizer uptake process into suction pipelines of pumping stations with a jet apparatus

Determination of the total energy in suction pipeline a four-component mixer fertilizers and water an experimental way, for possibility its use various schemes cropsirrigation has been performed. Materials methods: The research was carried out at operating pumping station LLC “Rassvet” Kuibyshevsky district Rostov region on specially made installation using calibrated control measuring devices accordance with GOST 24028-80 “Research tests”. results’ processing according to recommendations V.N. Voznesensky theory experiment planning. experiments were two stages, first determine factors influencedegree: В1– vacuum value, accepted values 0÷9 m, В2 – value pipe centrifugal pump, assumed 0÷5 H1 head jet taken within 0÷25 full mixerS (pressure + velocity head), which subsequently determined all hydraulic parameters line (pipe diameters, distance mixture transportation, loss pipeline. According stageresults, influencedegree criterion - is 66.37%, 26.32%, 7.3% second stage most significant factors, HIand pump В2. Based results group experiments, equation, analysis it possible variationstudied intervals obtained.
