Agricultural irrigation relies heavily on water pumps, which transport water from the source to the fields and crops. Drip irrigation, sprinklers, or a hose can all be utilized with a water pump.
Pumps can be driven by fossil fuels or electricity, or they can be controlled by a simple hand crank.
What is the mechanism of a water pump?
While there are a variety of ways in which water pumps can function, in their most basic form, they include three major components: an intake, pump system, and output.
When a pressure differential occurs inside the pump system, water is pushed into the pump from the intake side. Water seeks to travel from a high-pressure to a low-pressure location. A hose is used to transfer water from the pump to your farm or water tank once it exits the pump.
A water motor may be divided into two primary categories based on how it creates pressure differences inside the pump system. The following are examples of these kinds:
Proportional Reduction By altering the volume (space) available within the pump system, water pumps produce a pressure differential. The pump’s inlet pressure is reduced by using components like pistons, closed chambers, and valves. The water is then displaced (forced) through the pump system’s exit as a result of the higher pressure.
This type of pump uses spinning blades, known as “impellers,” which convert rotational motion into fluid motion to move liquid through a series of pipes.
These pumps all require a source of energy in order to function, and this energy can come from either fuel or electricity, or from you physically moving the pump components using a lever.
Types of Pumps
Water pumps come in a variety of shapes and sizes such as centrifugal pumps and it can be hard to know which one is ideal for your farm. When selecting a water pump, keep in mind your budget, the size of your farm, the water supply, the amount of water you require, and your power source.
It is important to consider your water supply while deciding which water pump to purchase. A surface Water Pump is appropriate if you have a surface water supply, such as a river, lake, water pan, tank, or even a very shallow well or borehole, with a water level ranging from 0 to 7m (0 to 23ft).
Water pumps for irrigation are connected to a hosepipe with a filter.
Submersible Water Pumps are required if the water source is deeper than this. This is due to the fact that surface-mounted pumps are unable to raise water more than 7 meters below the surface. What is known as a pump’s Total Head is how high it can raise water (or total lift).
A hose from the inlet side of the water pump is inserted into the water to supply the pump with water. In order to supply your farm, these pumps pull water into the pump system and then push it out.
An underwater submersible water pump is installed. In order to function properly, these pump systems’ power lines and outlet hoses must be watertight. Using these pumps, water may be pumped all the way up to your farm from the pump’s submersible depth.
To put it another way, the higher the head the slower the flow rate will be since it takes more energy to move the water. For the same amount of energy, submersible pumps from higher depths (big head) will generate less water than surface water pumps from shallow sources (shallow sources) (low head).
