3-8kw Automatic Hydro-generating Unit

 

  1. General: This kind of units is applicable to the remote mountainous areas lacking of technique and the difficulty in purchase of fitting and in maintenance for the remote mountainous areas, this type of units is designed and manufactured for long lifespan. And the structure is simple and reasonable, with fewer parts, and it has properties of low cavitation noise, good performance, easy and convenient operation and maintenance. The generator can be automatically controlled, and the voltage and frequency is automatically stable. And 24-hour watch is unnecessary.

2. Structural Description: This automatic hydro-generating unit is made up of the following equipment. Turbine: for the water head less than 15 meters, shaft extension, horizontal tubular turbine is adopted. Via the stay vane water flow is introduced into the runner. The turbine guide bearing is made of anti-wear material. Filtering device is designed to filter. The structure of the whole set is simple and reliable. Elastic coupling is used to connect the generator directly. And all-purpose pulley can be used to directly drive agricultural machinery. And for water head of over 15 meters, vertical angular impulse turbine is adopted. The generator shaft is extended into turbine, and directly connected to the turbine runner. At turbine inlet, needles are set to adjust the water flow of turbine. Butterfly valve: used to control the switching of the turbine. Before the valve, diversion by steel pipe is adopted. Generator: Using 3-phase AC synchronous generator. Control cabinet: having collection and display of parameters of voltage and frequency of generator, voltage adjustment, over-current protection. The generator and the control cabinet are made into an integral one and easy for operation. Electric load adjustor: when the unit is generating, it is automatically monitor the variation of load, adjust the “false load” at any time to balance the output power of unit and total load of power utilization, automatically control the stability of unit’s voltage and frequency and make the unit under stable operation. It is automatic operation when generating, and 24-hour watch is unnecessary. “False load” adopts high-quality electric heating tubes mounted in the water tank for cooling with water, or adopts electric furnace for heating and power expenditure.

3. Technical parameters of the unit: Rated capacity: 3, 5, 8kw Rated voltage: single phase 220 V Frequency 50Hz Rated speed: 1500rpm Generator efficiency: 80% Power factor: 1 Variation of frequency: 49-51Hz Variation of voltage: 200-230V Diameter of butterfly valve Ф200mm Nominal pressure: 1.0 MPa
