Combustion engine water pumps for irrigation are devices designed to operate in harsh environments and handle large volumes of water. Their construction is based on key components that determine their efficiency and functionality.

The operation of irrigation water pumps begins with starting the engine, which drives the impeller inside the pump body. The impeller creates a pressure difference that draws water through the inlet pipe and pushes it out through the outlet pipe. This mechanism allows large amounts of water to be transferred quickly and efficiently, making water pumps indispensable tools in many practical applications.

Here is a detailed description of the components and their operation:

• Internal combustion engine: The heart of the water pump is a combustion engine that can be powered by a mixture (two-stroke), petrol (four-stroke), or diesel. Four-stroke engines are preferred for their greater quietness and efficiency compared to two-strokes.
• Pump body: Made of corrosion-resistant materials such as cast iron or aluminium, the pump body contains the pumping mechanism. The robustness of the material is crucial for the device's durability, especially when dealing with dirty or chemical water.
• Impeller: Inside the pump body, the impeller is the rotating component that pushes water through the system. Its configuration determines the pump's capacity and head.
• Suction and delivery system: The pump is equipped with an inlet (suction) and an outlet (delivery). The diameter of the fittings, which can vary from 25 to 50 mm, affects the water flow rate, which can reach up to 1000 litres per minute.
• Filters: For dirty water pumps, the presence of filters is essential to prevent debris and particles from damaging the impeller and other internal components.
• Frame and configuration: Water pumps can be portable or mounted on a frame. Portable versions are ideal for dynamic work, while those on a frame are intended for static installations.
• Starting system: Some models are equipped with electric start, allowing the engine to be started with a key or button, greatly simplifying use compared to manual pull-start.

An irrigation pump works by using an engine that creates mechanical movement to move water. The engine can be electric, petrol, or diesel. The operation takes place in two main phases:

• Suction: The pump creates a low-pressure area at the inlet, drawing water from a source such as a well, tank, or watercourse. The water enters through a non-return valve that prevents backflow.
• Delivery: The engine's movement pushes the water through a piping system to the sprinklers. The generated pressure allows the water to reach long distances and different heights.

Irrigation pumps can be classified based on their capacity and pressure:

• Centrifugal pumps: Use an impeller to create a continuous flow and are suitable for large volumes of water.
• Volumetric pumps: Provide a constant flow regardless of pressure, ideal for small systems.

Calculating the flow rate of an irrigation pump is essential to ensure effective irrigation. The flow rate is measured in litres per minute (L/min) or cubic metres per hour (m³/h) and depends on various factors:

• Water source: The capacity and availability of the water source.
• Desired pressure: The pressure needed to reach the sprinklers.
• Length and diameter of the pipes: The pressure losses due to the internal friction of the pipes.

The formula to calculate the flow rate is: Q= A × v

Where Q is the flow rate (m³/h), A is the area of the pipe section (m²), and v is the water velocity (m/s).

Another method is to use a flow meter that directly provides the reading based on the system configuration.

Calculating the flow rate of an irrigation system involves analysing the water needs of the plants and the system's capacity. Here are the main steps:

• Determine the water needs of the plants: Consider the type of plants, climate, and soil type.
• Calculate the irrigated area: Measure the total area that needs irrigation.
• Estimate the irrigation time: Based on the time needed to provide adequate water without waste.

The formula for calculation is: Q= (A×D×E) / T

Where Q is the required flow rate (L/min), A is the area (m²), D is the water need (mm/day), E is the system efficiency, and T is the irrigation time (minutes).

The number of litres per minute for irrigation depends on various factors, including the type of plants, the size of the area, and the capacity of the irrigation system. Here's how to determine the amount:

• Type of plants: Some plants require more water than others. For example, lawns have a higher water need than succulent plants.
• Area size: Measure the area to be irrigated.
• System efficiency: Consider water losses and the efficiency of the sprinklers.

An example of calculation:

Flow rate= (Area × Water need) / Irrigation time

If the area is 100 m² and the water need is 5 mm/day, and you want to irrigate for 1 hour:

Flow rate= (100 × 5) / 60 = 8.33 L/min

The pressure needed for an irrigation system varies depending on the type of sprinklers and the system configuration. Pressure is measured in bars or psi and must be adequate to ensure optimal water flow. Here are the main factors to consider:

• Type of sprinklers: Spray sprinklers require a pressure between 2 and 3 bars, while drippers work effectively at lower pressures around 1 bar.
• Length of the pipes: Pressure losses increase with the length of the pipes. Calculating pressure losses is essential to determine the pressure at the source.
• Ground height: If the irrigation system must overcome elevation differences, the pressure must be sufficient to compensate for the additional height.

To determine the necessary pressure, you can use the following formula:

Ptot = P irr. + P losses + P elevation

Where Ptot is the total required pressure, P irr. is the operating pressure of the sprinklers, P losses are the pressure losses in the pipes, and P elevation is the additional pressure needed to overcome elevation differences.

The water consumption of an irrigation system depends on the type of plants, the area to be irrigated, and the type of irrigation system used. Here's how to calculate consumption:

• Water needs of the plants: Various plants have different water needs. For example, a lawn may require 5-10 mm of water per day.
• Area to be irrigated: Measure the total surface area in square metres (m²).
• Type of irrigation system: Drip systems are more efficient than spray sprinklers.

To calculate daily consumption:

Daily consumption = Area × Water need

For example, for an area of 100 m² with a need of 5 mm/day:

Daily consumption = 100 × 5 = 500 litres/day
