Estimates the required head for pumping station automatic watering systems can use a simplified calculation: the pressure is defined as the sum of the required pressure at the point of use, expressed in meters (for example, 2 bar = 20 m water column), the maximum depth suction, the maximum depth of effort and 15% of the total pipeline length (this is roughly equivalent to loss of pressure, which caused friction within the water suction pipe). Thus, we have identified "Working point" of the pump. Now in the directory of pumping equipment for the hydraulic diagram of the curve of each pump should find a point of intersection between the two data points. If the "working point" Use is above the curve, then the characteristics of the pump does not meet the requirements of your system's automatic watering. When it is below the curve – the pump meets the requirements of your avtopoliva site. To get started, any pumping station automatic irrigation system does not require any additional training, immediately after installation and integration, they begin to pump water, while not necessarily pre-fill the suction line as for the other pump. Preconditioned to a water source is necessary.
If you can not pump out water from the spring until the water goes completely cleared of sand and mud, the suction required to use special cleaning filters. Also, be sure that the performance of the pumping station is not greater than the debit of water source for automatic watering systems. Launch pumping station for the automatic irrigation occurs after the pump is filled with water through the filling hole. Water-air mixture is obtained when you first start pumping station, creating a vacuum in the desired suction port, and thus there is a rise of water from the source. Formed in the pump air out through a special valve.
Pumping station before starting to fully check for leaks suction line. In this case the required pressure in the pressure vessel must comply with 0.9 of the inclusion pressure. In the setting of pressure pumping station off and on by means of a pressure switch. Modern technologies allow the use of automatic watering systems for virtually any water source with a sufficiently large debit. Optimally balanced pump or pump unit can meet the demand for water is not only automatic watering system, but also supply all the country house.
