Pure, non-professional physical calculation.
Based on 2.5 kilowatts of cabinet air conditioner:
mgh=2500
mg=2500/50=50kg/s
< p>Also In other words, if all the gravitational potential energy of the water is converted into 220 volts of electrical energy, the flow rate must be 50 liters/second.In fact, the efficiency of this type of micro-hydraulic power generation unit may not reach 40%, and the undervoltage operation of the air conditioner can easily burn the compressor, the input power must therefore have a margin, then:
The required flow rate is at least (50/0.4)/0.8=156 liters/second
The above only provides ideas, the data cannot be used! This can be tried as a hobby and makes little business sense.
What is the load of a hydrogenerator? As well as charge rejection, vacuum and the difference between empty rejection and charge rejection
“Vibrationn hydraulics is important,< /p>
It is necessary to operate with a large load." Perhaps a civil engineer has told you. For the operation of Francis or flow turbines axial, poor operating conditions of small loads should be avoided. It is correct to operate under the optimal operating conditions of larger loads. The vibration may be lower in the normal area. of water is important, this means that your unit may have other problems, and blindly avoiding them is not a long-term solution.
The rotor of the hydroelectric generator is in trouble again. load shedding. The phenomenon of occurs, why?
Hydraulic generator load - refers to the nominal load of the generator. sudden loss of load when the generatorr works with load. No-load – refers to the generator operating without a load. The difference between no load and load shedding - no load means there is no load, and load shedding means there is load at first, then suddenly loses load and becomes no load. charge. sudden change problem.
It should be the generator
Bearing
The gap is too large during load shedding
Generator rotor
>Due to sudden acceleration and loss of stability! Only then will he jump up and down! This is not easy to detect during normal power production. If you stop the generator and lift the shaft sharply, you will find the gap in the bearing (bearing sleeve)!
