      Rain gun irrigation design and installation

On the installation and design of the rain gun, the irrigation designer must understand the working pressure and the flow rate of the gun, plant water requirement per irrigation cycle, type of the plant, climatic conditions, and the topography or the slope of the farm.

After considering these factors, proceed with the pump sizing. Pump sizing is the process of matching the pump water pressure and flow rate to that of the rain gun against a gradient to ensure the wanted quantity of water is discharged at the designated region.

Pump sizing is the mother of all designs of rain gun sprinklers since the pressure from the pump is what will exert pressure in the water to rotate the gun.

When sizing the water pump, first consider the head of the gun. Let’s say the gun has a head of 30 meters or 40 meters which is the normal working pressure of most guns with the working flow rate of 25 cubic meters per hour the water pump size one will require will be at least twice times the head of the gun (30mx2=60) and twice the water flow rate of the gun (40 cubic meter per hour).

Rain gun sprinkler installation continuation

After sizing of the water pump then proceed to rain gun installation. For installation of the gun, one will need, delivery pipe, pipe fittings e.g. tees, elbows, and adapters of the required sizes, hacksaw and the blades, safety gears, and any other tool and good sound of mind.

1. Connect the rain gun head to the tripod stand and ensure the stand is firm enough to avoid toppling when the gun is rotating
2. Attach a PVC, HDPE, or delivery pipe to the rain gun sprinkler inlet at the base. At this point consider the threads. From the thread positioning either internally or externally one can choose the pipe to gun adapter

• Adjust the water gun sprinkler to the desired angle of irrigation water delivery. This is done by adjusting clips below the gun head.

1. Start your irrigation water pump at 20 starting /hour then adjust the throttle with time.
2. Walk along the delivery pipes to the gunpoint to check for any leakages because leakages reduce the pressure of the water pumps, therefore, resulting in lower efficiency.

   The differences between rain guns and the sprinklers

Sprinkler head

1.  Rain gun sprinklers available for sale in Kenya have a large area coverage. The gun sprinkler, replace 8 to 15 sprinklers as per the model chosen. It, therefore, reduce labor requirement to great extent in shifting the sprinklers in the farm area.
2. Rain gun sprinkler also gives choice to use as full or partial circle rotation with droplet size management mechanism for optimum working under windy conditions
3. Turbine drive models are gear-driven wherein their rotation speed is unaffected by changes in wind velocity and thus offers the highest uniformity of rain all over the area and hence are more costly.
4. They are best under windy conditions at the site and preferred for high precision sprinkling.
5. Rain gun sprinkler for sale in Kenya is suitable for most high crops like fodder, maize, vegetables like Onions, carrots, grains and, pulses, plantation crops such as coffee, tea, cardamom, sugarcane, etc.,

     Advantages of rain gun for sale in Kenya

1. Highly energy efficient, Long lasting and trouble-free
2. Since the jet sprinkles over a large area, it avoids setting up a large number of smaller jets.
3. Reduces labor cost, because the pipeline within the estate is minimized so also the number of jets.
4. The precipitation varies with the nozzle size, but unlike conventional jets, overlapping is not necessary.
5. This reduces the time required for irrigation as well as the savings on diesel.
6. Time is the essence in Robusta sprinkling and the eventuality of insufficient natural rain, more are can be covered with the help of these jets.
7. The jets are rugged and only require periodic greasing. Ease of installation, assembly, and maintenance
8. The trajectory of the throw of water is such that the damage to pepper vines is negligible.
9. Part circle adjustments save water from going into neighboring plantations.

  Disadvantages of rain gun sprinkler for sale

1. The rain gun sprinkler and the raiser pipes are very heavy.
2. High daytime temperatures result in evaporation loss.
3. Not suitable in areas with high-velocity Winds.
4. The prohibitive cost of rain guns.
5.  Require expertise especially during the design

• Ensure all materials are present including pipe fittings, elbows, sockets, connectors and accessories, delivery pipes, blades, and safety tools.
• Pump sizing is a very crucial thing to consider first before handling anything else. The pump size should be twice the diameter of the gun and twice the flow rate of the gun.
• Connect the rain gun head to the tripod stand and ensure the stand is firm enough to avoid toppling when the gun is rotating
• Attach a PVC pipe, HDPE, or delivery pipe to the rain gun sprinkler inlet at the base. At this point consider the threads. From the thread positioning either internally or externally one can choose the pipe to gun adapter
• Adjust the water gun sprinkler to the desired angle of irrigation water delivery.
• Start your irrigation water pump at 20 starting /hour then adjust the throttle with time.
• Walk along the delivery pipes to the gunpoint to check for any leakages because leakages reduce the pressure of the water pumps, therefore, resulting in lower efficiency.

Precautions to Be Taken While Installing & Dismantling of Rain Gun:

• The nozzle size should be according to the designed rating while replacing the nozzle using the right tool.
• While the sprinkler is in rotation, particularly in the case of impact Rain Gun, one should stay away about 1meter to avoid any harm from its fast reverse rotation.
