5 Factors to think about when selecting irrigation pump

rrigation pumps are normally used to pump water from a lower to the next level from which the water then flows via channels to the fields requiring irrigation or to lift it to the required pressure head so as to spray the fields by way of piping techniques (sprinkling). The heads involved vary from approx. 1 m for regular raise operation to 40 m for sprinkling. Ocassionally, heads greater than one hundred m could additionally be required.
At occasions, irrigation pumps are usually not geared up with variable speed drives. pressure gauge น้ำ can due to this fact be controlled 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 speed 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 doesn’t mean that each one irrigation strategies are equally helpful. Knowing what is going to work best in your situation requires data in regards to the choices obtainable, together with the advantages and disadvantages of every. With that in thoughts, here is a look at 5 issues to consider in getting water to your crops:
1. Soil sort. The type of soil in an area can have an effect on not solely the sort of irrigation method used but additionally the irrigation run instances. Sandy soils sometimes require frequent purposes of water at a excessive fee to keep moisture in the root zone. Clay soils has a characteristic of holding moisture longer that sandy soils, even so, this may require frequent purposes at a decrease rate to stop runoff.
2. Land topography. When it involves land considerations, hilly or sloping land can be a problem. Drip irrigation works nicely if the laterals could be run alongside topographic traces. Often system run instances could have to be adjusted to prevent runoff. Travelers and heart pivot techniques are usually out of the question on hilly and severely sloping land.
three. Local climate patterns. In this case, sprinklers are much less desirable in areas where excessive winds are common and in arid areas with a low humidity since water losses as a end result of evaporation may be extremely high. Drip irrigation works well for both of the above talked about conditions.
four. Type of crops grown. Sprinkler and drip systems can require excessive levels of funding. Therefore, it’s better to order their use for high-value crops like vegetables, small fruits and orchard crops quite than applying them to commodity crops like wheat and soybeans.
5. Water quality. All drip irrigation methods require some sort of filtration. Overhead systems similar to sprinklers seldom require filtration. Irrigation water ought to be examined for water borne pathogens. Depending on the crop grown and irrigation technique used chlorine injection could additionally be required. Other water high quality issues that could be of concern embrace levels of soluble iron and different dissolved minerals.
