5 Factors to contemplate when selecting irrigation pump

rrigation pumps are normally used to pump water from a lower to a higher stage from which the water then flows by way of channels to the fields requiring irrigation or to boost it to the required pressure head so as to spray the fields through piping methods (sprinkling). The heads concerned vary from approx. 1 m for normal lift operation to 40 m for sprinkling. Ocassionally, heads more than one hundred m could additionally be required.
At times, irrigation pumps are often not outfitted with variable velocity drives. The move price can therefore be managed by both switching the pumps on and off, or by using a throttling valve in the discharge pipe, pre-swirl management (e. g. cooling water pumps), rotational velocity or impeller blade pitch adjustment. เครื่องมือที่ใช้ในการวัดความดัน 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 food for the world. However, this does not imply that every one irrigation methods are equally helpful. Knowing what will work best in your state of affairs requires data in regards to the options available, together with the benefits and drawbacks of every. With that in mind, here is a look at 5 issues to contemplate in getting water to your crops:
1. Soil kind. The type of soil in an space can affect not only the kind of irrigation methodology used but additionally the irrigation run occasions. Sandy soils sometimes require frequent purposes of water at a high price to maintain moisture within the root zone. Clay soils has a attribute of holding moisture longer that sandy soils, even so, this will require frequent applications at a decrease rate to stop runoff.
2. Land topography. When it involves land issues, hilly or sloping land can be a problem. Drip irrigation works nicely if the laterals can be run along topographic lines. Often system run occasions might need to be adjusted to stop runoff. Travelers and middle pivot techniques are normally out of the question on hilly and severely sloping land.
three. Local climate patterns. In this case, sprinklers are much less fascinating in areas the place high winds are frequent and in arid areas with a low humidity since water losses as a result of evaporation may be extraordinarily high. Drip irrigation works nicely for both of the above talked about conditions.
four. Type of crops grown. Sprinkler and drip methods can require high ranges of funding. Therefore, it’s higher to reserve their use for high-value crops like vegetables, 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 kind of filtration. Overhead systems such as sprinklers seldom require filtration. Irrigation water must be examined for water borne pathogens. Depending on the crop grown and irrigation method used chlorine injection may be required. Other water quality points that could be of concern include ranges of soluble iron and other dissolved minerals.
