Vertical pumps PVN 650/50 and PVN 1000/35
- centrifugal, vertical, one-stage with a console arrangement of the driving wheel of the closed type. For an exception of the modes of cavitation the screw on one shaft with a driving centrifugal wheel is installed in the pump and steady "vsas". Are intended for pumping of various abrasive hydromixes (suspension of ores, a pulp) on the basis of technical water with a density no more than 1140 kg/m ³, having firm inclusions no more than 1 mm in size which volume concentration does not exceed 2%, with a temperature from 20 to 95 °C, with rn from 4 to 6 at the enterprises of the metallurgical, oil and gas industry. A working environment - the ore suspension representing hydromix of particles of the processed ore with technical water and special additives. Structurally PVN 650/50 and PVN 1000/35 units consist of the pump which is over the support plate and the shipped part consisting of the filter, the valve of the reception return and the connecting pipes. The valve reception is intended for filling of the pump with a working environment before start of the unit in work. Selection of length of pipes of submersible part of the unit allows to provide the necessary depth of immersion. The design electric pump the unit allows to automate remotely process of inclusion and switching off of the electric pump unit after filling of working liquid at installation of the sensor relay of level of filling. Vertical units compactly are placed to technological lines, without demanding development of the areas, both in shops of subjects of reconstruction, and in again projected. Are convenient regarding their automation at inclusion and switching off on a reference level of the pumped-out environment in capacity. PVN 650/50 and PVN 1000/35 units are completed with asynchronous three-phase electric motors of the closed blown execution with a short-circuited rotor with execution on installation of IM 2081 (lapo-flange), IM 3081 (flange). Engines are intended for work from the alternating current main of 50 Hz, of 220, 380, 660 Century. If necessary the PVN 650/50 and PVN 1000/35 electric pump units can be completed with electric motors of explosion-proof execution. The cavity of a krylchatka is condensed with hydrodynamic consolidation. Protection of bearing knots against hit of working liquid is provided with omental uncooled consolidation.
