How do I know what size irrigation pump I need?
To determine the correct sprinkler pump size, you’ll first need to figure out how many sprinkler heads you have along with their GPM (gallons-per-minute) and PSI (pounds-per-square-inch) requirements. All sprinkler heads are rated at a specific GPM and PSI.
Which motor is used for irrigation system?
A pump motor consists of two parts: first is the Pump and second is the Motor. The Motor provides the energy to the Pump which will create the required water Head Pressure. Two pump motors of same horsepower may not perform in same way in a system of irrigation.
What are the criteria for pump selection?
What information is required to make a pump selection?
- Liquid name. Knowing the liquid that you are pumping is vital as it allows us to ensure that we offer a pump constructed from compatible materials; thus avoiding potential corrosion and abrasion issues.
- Flow rate.
- Pressure.
- Viscosity.
- Density.
- Temperature.
How do you calculate pump motor kw?
Pump Power calculation Formula: Pump Power P(kW) = q(m3/hr) x ρ(kg/m3) x g(m2/s) x h(m) x p(Pa) / 3600000. The same way pump power in horsepower formula can be written as, Pump Power P(HP) = q(m3/hr) x ρ(kg/m3) x g(m2/s) x h(m) x p(Pa) / 2685600. Also above pump power is required to lift the liquid to head meters.
How do I choose an irrigation pump?
When selecting an irrigation pump, consider the pump’s operating conditions, including:
- the type of water source.
- the required pumping flow rate (determined by the irrigation system requirements)
- total suction head (lift from the water surface to pump intake)
- total dynamic head (total pressure supplied by the pump)
How do I choose a pump type?
Flow rate: Calculate your desired flow rate by multiplying the total volume by the time in which you want to move the liquid. For example, for a 500-gallon pond that needs full circulation once an hour, you would want to select a pump with a minimum rated flow rate of 500 GPH (gallon per hour).
Which pump is best for irrigation?
Horizontal centrifugal pumps
Horizontal centrifugal pumps are the most common for irrigation. They generally offer lower cost, require less maintenance and are easier to install and inspect for maintenance than other types.
Why pumping is needed in irrigation?
Pumping systems play a vital role in providing optimized solutions for energy and water use. A pump system for today’s irrigation is not only about the pumps. Variable speed drives, intelligent control and remote management all necessitate the integration of components in an irrigation system.
How is pump rating calculated?
Calculations:
- Flow Rate (Q) =Q1x1.
- Actual Total Head (After Friction Losses) (H) = (h1+h2)+((h1+h2)xf)
- Actual Total Head (After Friction Losses) (H)=50+(50×30%)= 65 Meter.
- Pump Hydraulic Power (ph) = (D x Q x H x9.
- Pump Hydraulic Power (ph) = (1000 x 0.005 x 65 x9.
- Motor/ Pump Shaft Power (ps)= ph / pe = 3 / 80% = 4KW.
Which is the best description of lift irrigation?
Lift irrigation is a mode of irrigation which involves transporting water against the gravity with the help of pumps or surge pools and transported to the location where it is to be used. As mentioned earlier, lift irrigation is comparatively newer form of irrigation and has been introduced in Maharashtra after 1960s.
How is lift irrigation used in Maharashtra state?
For the regions which are above the water level, list irrigation has acted as a boon. In lift irrigation, water is carried from a lower level to a higher level using pumps or other pumping mechanisms. In the state of Maharashtra, a significant portion of irrigated area deploys lift irrigation.
How to choose the best motor for your application?
In choosing a motor for these conditions, consider the highest continuous load point, which typically occurs at the highest speed. The rule of thumb for motor horsepower is: Select only what you need, and avoid the temptation to oversize or undersize. Calculate the required horsepower from this formula: Where torque is in lb-ft and speed is in rpm.
What should be considered when selecting a crane motor?
Most vital and primary technical consideration for selection of the motor for any particular application is the torque required by the load during starting and acceleration periods, especially the relationship between the maximum torque or breakdown torque generated by the motor and the start-up torque or locked rotor torque for both periods.
