Q:I have a mechanical well how to choose the size of the pump
Deep well pumps can be used. According to your parameters. 0. 75 or 1. The 1KW deep well pump is in line with your requirements. Elephant 0. 75KW head can reach 70 meters. The water output in an hour is about 3 tons.. I wonder how much you get out of the water every hour. If the amount of water is small, you can buy a larger power point. General domestic deep well pump 0. 75 or 1. The price of 1KW is between 500-700. In the case of ordinary brands. The price of imported goods is between 600-900. The products at this price are generally of good quality.. Of course they don't sell your shoddy premise.
Q:Why can't sprinkler system and hydrant system share water pump in fire fighting system?

Q:Pump frequent start will reduce the service life, I ask what kind of frequency is called frequent start?
Pump is the same, often start, not just reduce the service life of the pump, motor, contactor life will be shortened.
Q:Is it illegal to produce aluminium submersible pumps?
When buying, if you ask for a copper wire or a wire, and don't answer you, it's against the principle of good faith. On the contrary, if you did not ask to buy the water pump with aluminum core, then there is no violation. Because the country does not have any laws and regulations prohibiting the production of aluminum core wire motor, naturally there is no aluminum wire motor as a fake and shoddy products, there is no pre notice obligations.In fact, the aluminum core motor is good, and the price is low, especially in the dry environment of small and medium-sized motors, with good performance. Only used in submersible pumps, because aluminum is easier to damp than copper wire, due to bacteria and other corrosion, and its life is sometimes less than copper wire. But the water pump, aluminum often needs to rewind coil, because of a small submersible pump motor is not good around general scrap.
Q:Safety head of water pump?
In fact, to prevent pipeline errors, generally take 0.5 meters margin, just in case the pipeline changes, resistance, and do not smoke Sheung Shui
Q:Three phase water pump rated power 4000W, is three-phase working water pump, the voltage is 380V, how to find the three-phase pump current, and calculation of public
Three phase water pump motor rated power 4000W is the output shaft power, divided by the motor efficiency (general 85%) is the input power, which is often mistaken. The electric power is =4000/0.85=4706WRated current = electric power /1.732x, rated voltage x, power factor =4706/1.732x380x0.8=8.94A (assuming power factor 0.8).The above three answers are all wrong.
Q:Diving pump voltage
Small amount of water, it should be the lift can not meet the requirements, change the submersible pump is the best solution. With 380 volts, it is very likely to burn out the pump motor.
