5 Factors to consider when choosing irrigation pump

เครื่องมือที่ใช้วัดความดันคือ are normally used to pump water from a lower to a better stage from which the water then flows through channels to the fields requiring irrigation or to boost it to the required strain head in order to spray the fields by way of piping systems (sprinkling). The heads involved range from approx. 1 m for regular lift operation to 40 m for sprinkling. Ocassionally, heads more than a hundred m may be required.
At times, irrigation pumps are usually not outfitted with variable velocity drives. The move price can therefore be controlled by both 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 pace 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 each one irrigation methods are equally helpful. Knowing what’s going to work best in your situation requires knowledge in regards to the choices out there, together with the benefits and disadvantages of each. With that in thoughts, here’s a take a glance at 5 issues to consider in getting water to your crops:
1. เกวัดแรงดันน้ำ . The kind of soil in an area can have an result on not only the kind of irrigation technique used but in addition the irrigation run instances. Sandy soils usually require frequent purposes of water at a high fee to keep moisture in the root zone. Clay soils has a attribute of holding moisture longer that sandy soils, even so, this may require frequent applications at a lower price to forestall runoff.
2. Land topography. When it comes to land considerations, hilly or sloping land could be a problem. Drip irrigation works properly if the laterals may be run alongside topographic strains. Often system run occasions may need to be adjusted to forestall runoff. Travelers and heart pivot systems are usually out of the query on hilly and severely sloping land.
three. Local weather patterns. In this case, sprinklers are much less fascinating in areas the place excessive winds are frequent and in arid areas with a low humidity since water losses due to evaporation could be extraordinarily excessive. Drip irrigation works nicely for both of the above talked about situations.
four. Type of crops grown. Sprinkler and drip techniques can require excessive ranges of investment. Therefore, it’s better to order their use for high-value crops like vegetables, small fruits and orchard crops somewhat than making use of them to commodity crops like wheat and soybeans.
5. Water high quality. All drip irrigation techniques require some kind of filtration. Overhead techniques such as 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 points that could be of concern include levels of soluble iron and different dissolved minerals.
