1. Turn off the generator set, disconnect the power supply, and turn off the cooling system, including water pumps, water tanks, pipes, etc., to ensure that no water enters the generator set during operation.
2. Disconnect the connection between the water tank and the generator, including water pipes, water level gauges, etc., disassemble the water tank, move it to a safe place and ensure you that there is nothing. residual water or other impurities.
3. Clean the inside of the generator set, including removing carbon deposits, replacing lubricating oil, etc., check the generator set for damage or malfunction, and make necessary repairs and replacement parts.
I have a 2 kW Zongshen gasoline generator with an excitation voltage of 70 and a voltage of 150. After the excitation wire is connectedhey, the motor seems unable to load. Please enlighten me, Ma Ming. 'an
2.2 M For waterfalls, the maximum water height is 2.2 M. Take 2M for calculation, and the flow rate is 1L/S. Gravitational potential energy T=mgh, P=mgh/t=1000*10*2=20000J/s=20000/3.6=5.5KW
The efficiency of the original owner's homemade turbine will not exceed not 50% because that's too small.
The motor efficiency will not exceed 85%
The power is therefore conservatively estimated at around 2 kW.
Since the water level is too low, the poster needs an axial flow vane turbine, and he can make one himself. Next, engage the gearbox at high speed. This can achieve higher efficiency.
Since the power is too low, a 3 kW DC motor can be used with a relatively simple structure, and then an inverter can be added.
Brother, I can definitely tell you that the electric machinectric is sexy. If the voltage is 150V, the primary winding is not bad, but the secondary winding is bad. . Generators from this brand can handle an overload under normal circumstances. The solution is to buy a 2.5KW generator and install it, so it can drive your load without changing the motor.
