rrigation pumps are usually used to pump water from a lower to a better level from which the water then flows via channels to the fields requiring irrigation or to boost it to the required stress head to be able to spray the fields by way of piping methods (sprinkling). The heads concerned vary from approx. 1 m for regular raise operation to forty m for sprinkling. Ocassionally, heads more than one hundred m could also be required.
At times, irrigation pumps are usually not geared up with variable speed drives. The circulate price can due to this fact be controlled by both switching the pumps on and off, or through the use of 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 more than 2,000 years farmers have used irrigation to develop meals for the world. However, this doesn’t imply that every one irrigation strategies are equally useful. Knowing what’s going to work best in your situation requires knowledge about the options obtainable, including the advantages and drawbacks of every. With that in mind, here is a look at five things to consider in getting water to your crops:
1. Soil kind. เกจ์แรงดัน of soil in an area can have an result on not solely the sort of irrigation technique used but in addition the irrigation run occasions. Sandy soils sometimes require frequent functions of water at a excessive price to maintain moisture in the root zone. Clay soils has a attribute of holding moisture longer that sandy soils, even so, this will require frequent purposes at a lower price to prevent runoff.
2. Land topography. When it comes to land concerns, hilly or sloping land could be a problem. Drip irrigation works well if the laterals can be run along topographic traces. Often system run times might must be adjusted to prevent runoff. Travelers and middle pivot methods are usually out of the question on hilly and severely sloping land.
three. Local climate patterns. In this case, sprinklers are less desirable in areas where excessive winds are frequent and in arid areas with a low humidity since water losses as a end result of evaporation may be extraordinarily excessive. Drip irrigation works properly for both of the above talked about conditions.
4. Type of crops grown. Sprinkler and drip systems can require high levels of investment. Therefore, it’s higher to reserve 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. เกจวัดแรงดันอาร์กอน require some type of filtration. Overhead techniques such as sprinklers seldom require filtration. Irrigation water should be tested for water borne pathogens. Depending on the crop grown and irrigation technique used chlorine injection could also be required. Other water high quality issues that might be of concern include ranges of soluble iron and other dissolved minerals.
