Product Description

Axial small-scale hydropower, mainly used in relatively low flow gap, for example, a small river, small dams edge. Axial small hydroelectric generators and impeller coaxial.  Small axial-flow hydropower machines generally work in between the head of 1 m -6 m.

Main specifications and technical parameters： Model type: axial flow permanent magnet water turbine generator    Power: 300W—8KW        Voltage: 110V、220V、380V       Frequency: 50Hz   60Hz         Water head: 2—8 meters           Flow: 0.025—0.18m³/sec Rotating speed: four poles 1,500 rpm; six poles 1,000 rpm; eight poles 750 rpm   Structure and working principle of the unit： Axial flow water turbine power generator is comprised of the water turbine and the generator sharing the same coaxial line. The water turbine is comprised of propeller, guiding cover, bearing, water seal and main shaft etc. The tail water pipe of axial flow water turbine power generator is utilized to form a vacuum suction pipe sucking water from upstream. Water forms a whirlpool while passing the volute and hits at the propeller, thus high speed rotation of the propeller is achieved and the generator is driven via the main shaft to generate power.   Characteristics of the generator：   The electric machine adopts efficient permanent magnet, thus it is provided with small volume and high efficiency. There are no wearing parts such as carbon brushes, silicon diodes and capacitors etc., thus it is provided with characteristics of few failures, easy and convenient maintenance. Working together with a regulator, the generator supplies stable voltage and is very suitable to be used by farmers in remote mountain areas.       Parameter table：
