5 Factors to consider when choosing irrigation pump

rrigation pumps are normally used to pump water from a decrease to a higher level from which the water then flows via channels to the fields requiring irrigation or to lift it to the required pressure head in order to spray the fields via piping systems (sprinkling). The heads concerned range from approx. 1 m for normal carry operation to forty m for sprinkling. Ocassionally, heads more than a hundred m could also be required.
At times, irrigation pumps are often not outfitted with variable speed drives. The move rate can due to this fact be managed by either switching the pumps on and off, or by using a throttling valve within the discharge pipe, pre-swirl control (e. g. cooling water pumps), rotational velocity or impeller blade pitch adjustment. Both horizontal and vertical pumps (e. g. tubular casing pump) are used as irrigation pumps.
For greater than 2,000 years farmers have used irrigation to grow meals for the world. However, this does not mean that all irrigation methods are equally helpful. Knowing what goes to work finest in your scenario requires information concerning the choices out there, together with the benefits and downsides of each. With that in thoughts, here’s a look at five things to contemplate in getting water to your crops:
1. Soil type. The sort of soil in an area can affect not only the kind of irrigation methodology used but additionally the irrigation run times. Sandy soils typically require frequent applications of water at a excessive rate to keep moisture in the root zone. Clay soils has a attribute of holding moisture longer that sandy soils, even so, this will likely require frequent applications at a lower rate to stop runoff.
2. Land topography. When it involves land considerations, hilly or sloping land can be a problem. Drip irrigation works properly if the laterals can be run alongside topographic strains. Often system run instances could must be adjusted to forestall runoff. Travelers and middle pivot techniques are usually out of the question on hilly and severely sloping land.
3. เกวัดแรงดันน้ำ . In this case, sprinklers are less desirable in areas the place high winds are widespread and in arid areas with a low humidity since water losses as a result of evaporation may be extraordinarily excessive. Drip irrigation works well for both of the above mentioned conditions.
4. Type of crops grown. Sprinkler and drip techniques can require excessive ranges of investment. Therefore, it’s higher to order their use for high-value crops like greens, small fruits and orchard crops somewhat than applying them to commodity crops like wheat and soybeans.
5. Water high quality. All drip irrigation systems require some sort of filtration. Overhead methods similar to sprinklers seldom require filtration. Irrigation water should be examined for water borne pathogens. Depending on the crop grown and irrigation method used chlorine injection could also be required. Other water high quality points that might be of concern include levels of soluble iron and different dissolved minerals.
