rrigation pumps are usually used to pump water from a decrease to the next stage from which the water then flows through channels to the fields requiring irrigation or to raise it to the required stress head in order to spray the fields via piping techniques (sprinkling). The heads involved vary from approx. 1 m for regular raise operation to forty m for sprinkling. Ocassionally, heads more than a hundred m may be required.
At occasions, irrigation pumps are often not geared up with variable speed drives. เกจวัดแรงดันถังแก๊ส can therefore be managed by both switching the pumps on and off, or by utilizing a throttling valve in the discharge pipe, pre-swirl management (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 develop food for the world. However, this doesn’t imply that all irrigation methods are equally useful. Knowing what is going to work best in your scenario requires data in regards to the options out there, together with the advantages and drawbacks of each. With ที่วัดแรงดันน้ำ in thoughts, here is a take 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 solely the type of irrigation methodology used but additionally the irrigation run instances. Sandy soils usually require frequent applications of water at a excessive fee to maintain moisture within the root zone. Clay soils has a attribute of holding moisture longer that sandy soils, even so, this will likely require frequent functions at a decrease rate to stop runoff.
2. Land topography. When it comes to land concerns, hilly or sloping land could be a challenge. Drip irrigation works properly if the laterals can be run along topographic strains. Often system run instances might have to be adjusted to prevent runoff. Travelers and heart pivot methods are usually out of the query on hilly and severely sloping land.
3. Local weather patterns. In this case, sprinklers are less fascinating 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 high. Drip irrigation works nicely for both of the above mentioned conditions.
four. Type of crops grown. Sprinkler and drip systems can require excessive levels of investment. Therefore, it’s higher to order their use for high-value crops like vegetables, small fruits and orchard crops quite than making use of them to commodity crops like wheat and soybeans.
5. Water high quality. All drip irrigation systems require some type of filtration. Overhead methods such as sprinklers seldom require filtration. Irrigation water ought to be tested 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 embody levels of soluble iron and different dissolved minerals.
