First determine what the static water level is in your well, which is the height of the water surface above the ground when the water pump is operating normally. Since we have not installed a water pump, we cannot measure this distance temporarily. so measure the distance between the water surface and the ground when there is no pumping. Subtract 10 meters from the value measured as net height. At this time, calculate the shaft power P = flow × head ÷ 102 ÷ 3.6 ÷ efficiency. The general flow rate of a 2-inch agricultural pump is between 20 and 30 cubic meters, and the efficiency is generally between 55% and 55%. About 60%, calculated based on the static water level of 30 meters, the flow rate takes the larger value, and the efficiency takes the smaller value P = 4.45 kW, which gives a margin of 20% = 5.3 kW, so the water pump power is 7.5 kW, calculated based on the die motor powersalt: 1 horsepower = 0.73549875 kilowatts, so the diesel engine chooses a minimum of 11 horsepower.
This method of watering the soil is quite expensive!
First of all, drilling water wells and hot springs requires preliminary geophysical exploration work. Then the construction site will be selected, depending on the geological characteristics, how many meters of water will come out. , and how deep it will continue to be drilled. This is hot spring water. If it is a well, it may be at a depth of 50 meters, 100 meters, 150 meters, 200 meters, 250 meters, 300 meters or even deeper. The water may have already come out, but it may not be hot spring water. How deep should the well be dug to obtain hot spring water, according to the characteristics of local geological resources, there can be hot spring water about 100 meters away? either 600 or 700 meters.Currently, geothermal heat pumps, air conditioning wells, etc. are used. also use underground thermal energy to meet the needs of social life.
