Units electric pump borehole ETsV10-120-80

Units electric pump borehole ETsV10-120-80, water supply of 120 m3/h (33,3l/sec.) a pressure of 80 m, speed of an el.dvigatel are 2950 rpm, engine capacity is 45 W, tension 380B. Are intended for water supply from boreholes, wells and water tanks. Are used for industrial and agricultural water supply, in construction, municipal, farmer and garden market-gardening services, and also for lowering of the level of ground waters. The unit electric pump borehole like "ETsV" represent the pump unit consisting of the centrifugal multistage pump and the submersible electric motor with rigid connection of their shaft the coupling. The rotor of the pump and a rotor of the electric motor rotate in rubber-metal bearings, bearings of the pump are greased with the pumped-out water. It is suspended in a well on a column of water lifting pipes and falls entirely to water. Materials of the main details of pumps - gray cast iron, carbonaceous steel, ftoroplast, plastic Borehole pumps ETsV never have to work "dry" - even short-term turning on of the pump in work without water leads to damage of bearings and windings of the engine. In the bottom of the electric motor the persistent bearing perceiving axial loading is located. On an entrance to pump part protective mesh - the filter protecting the pump from hit of large mechanical particles is established. The electric motor of the centrifugal pump PEDV which is water filled with a short-circuited rotor "a squirrel cage" with a synchronous frequency of rotation of a rotor to 3000 rpm. The winding of the stator is executed by a waterproof wire. Cooling of the electric motor is carried out by the pumped-over water. The unit is connected to a three-phase network 380B, 50 of Hz through the station of automatic control and protection Askad protecting the electric motor from work in the emergency modes.
