The pump can not choose a suit - fashion and beautiful. Selection should be based on parameters Wells. Almost all of the required information is contained in the passport outlet and documents at home (If the data does not appear, necessary to identify them).
In the shops deep pumps Available in a wide range, This complicates choice. What to buy pump – cheaper or more expensive – Here the choice is yours. But before purchasing should analyze the following parameters:
- Depth. The pump set at least 1 from the bottom of the hole.
- water Mirror – static water level in the off equipment.
- The dynamic level. Equipment set below.
- The diameter of the hole. An important parameter, required for the correct choice of the diameter of the pump. The diameter of the pump should be less than.
- Debit. Defining characteristics expenditures pump, the need to protect against dry run (directly affects the cost of equipment).
- The distance from the well of consumer (div. in terms of the exact number of areas). Important not only measure the horizontal distance, but vertically. This parameter defining characteristics of pressure.
- Superficiality (If several floors). It is important for the location of the top of the water intake.
pay attention! Dynamic water level measured at the included hardware - the distance from the water table to the surface of the earth (indicate in the passport wells). Indicators need to add on the distance to the top and add consumer 20-40 m (specific footage depends on the pipe section in the pipeline, its length; number of turns, if any; filters and necessary pressure at the outlet).
In addition to these important parameters:
- consumption;
- voltage (220/380);
- automation location (Accumulator, Collector and others.) - it is important to select and configure.
Water consumption is determined by the maximum number of simultaneously open taps. One valve open to full power - about 10 liters per minute. Need to count all the taps and multiply.
Example: bath + kitchen + restroom + washing machine = 40 liters per minute (2 m3 / year). means, You must purchase a pump with maximum efficiency at the rate 2 m3 / year (Efficiency indicates the manufacturer).
