Introduction: Aquacleaner Environmental is the leader in spot/suction. We offer many sizes and styles to choose from and maintain a good supply of various size hose clamps and couplings. 4 13.5hp pump w/hookah air and Diamond Head. We stock suction hoses for dredging, pressure hoses for powering dredges, and layflat hoses for highbanking use. We calculated size of suction flow’s active area and offered methods of active area sizing.We have hoses for most any application. The suction nozzle height adjustment travel limit switches turn off current to the independent motor at the extremes of the suction nozzle height to prevent. Velocity diagram analysis showed distance from the nozzle – air flow speed relation. suited for deep excavations as they have no suction lift limits. Experiment results enabled us to plot velocity diagram of suction flow and find maximum suction velocity: 26.74 m/s. equipped with a nozzle /venturi (eductor body) that is run by an at-grade pumping. One of basic parameters of pneumatic harvesting is suction velocity, that’s why field experiment for evaluation of KTT-2 machine suction nozzle performance was held. According to feedback from operators, these machines work well with high-moor peat but work much worse with low- moor peat which is of higher density. Market appearance of KTT-2 and MPTU-30 pneumatic harvesting machines promoted their introduction into operating processes of peat extractive companies. The advantage of the suction nozzle system is that you can dredge in very shallow water and walk around with the suction nozzle completely out of the water without effecting the performance of the sluice. However, in the late 1980s, due to the imperfection of the design of pneumatic machines, this method began to be used less and less frequently. ∗ Corresponding author: peat harvesting with pneumatic harvesting machines has a number of doubtless advantages over mechanical harvesting: operating time decreases down to 1 day, additional milling of wet peat deposit during the harvesting is not needed, list of necessary machinery decreases. The suction nozzle, usually made of steel. Tver State Technical University (TvSTU), 22 Afanasy Nikitin Emb., 22, Tver, Russia, 170026 Generally, recreational prospecting is considered to have an upper limit of 4-6 inches, depending on state law. Just about to have a 6 suction nozzle built/ modified. Is there a calc or a way to figure out how to get the correct volume/pressure ratio sorted. Alexander Yablonev ∗ and Darya Scherbakova Does pressure and volume cross over for a 6 dredge.
