The pump performance is indicated in the technical specifications of the device. If you need to determine the power you need, you need to calculate the water consumed by adding up the consumption of all simultaneously started devices in the apartment or in the country.
Necessary
- - technical passport of the pump;
- - calculation of the required power.
Instructions
Step 1
If you plan to install a pumping station with a storage tank, which will supply water to all points of the house or summer cottage, calculate the required water supply for simultaneously switched on devices. For example, if you simultaneously turn on the washing machine, dishwasher, use a faucet, shower stall, toilet bowl, add up all the indicators required to supply water to this type of equipment.
Step 2
To run the washing machine and dishwasher at the same time, you need 2-3 cubic meters of water per hour. In this case, the water pressure must be at least 3 m / s. Simultaneous switching on of the tap requires a water pressure of 1 cubic meter per hour with a pressure of 1-1, 5 m / s. For a shower cabin, you need a pressure of 2-3 cubic meters / h or 3 meters per second. Add up cubic meters per hour and meters per second. Basically, in the technical characteristics of the pump, the power is given in cubic meters, but some manufacturers indicate the power in meters, so calculate all the indicators.
Step 3
In addition, keep in mind that stationary pumps for individual use with the highest power suck up a column of water from a depth of 7-8 meters. Make sure the water column in your well is at this level. To do this, tie a nut to a strong thread and lower it into the well. This will make it possible to determine the level of the water column.
Step 4
If the water column is below 8 meters, then you do not need to calculate the performance of the pump you are buying, since a stationary pumping station for home use will not suit you, and all industrial pumps are very powerful and very expensive.
Step 5
When calculating the required power, be guided by the fact that a very powerful station is not always needed for domestic needs. Even if you bought the most powerful pump, but filling the well with water does not correspond to the required power, then you will have to start the devices in turn.
