The internal structural design of drip irrigation pipes

ON 01 . Jan . 2024

The internal structure design of drip irrigation pipes is a crucial part of the drip irrigation system, which is directly related to the uniformity of water release and the stability of the system.

Drip Hole Design: Drip holes are small holes inside the pipe that are responsible for releasing water to the plant roots. The location, number, and diameter of these drip holes are all factors that need to be carefully considered during design. The even distribution of drip holes ensures that plant roots receive an equal supply of water and avoids overly wet or dry areas. In addition, the diameter of the drip hole also directly affects the size of the water droplets, thereby affecting the water volume control of irrigation.

Spacing of drip holes: The spacing of drip holes refers to the distance between adjacent drip holes. The selection of this spacing needs to take into account the distribution of the plant's root system and the even release of water. Typically, an equidistant arrangement can better meet the water needs of plants and ensure that the entire area receives the appropriate amount of water.

Drip hole shape: The shape of the drip hole is also one of the factors that needs to be considered in the design. Generally speaking, circular drip holes are more common, but there are also some specially shaped drip holes, such as oblong or fan-shaped. These designs can better control the release direction of water droplets and improve water utilization efficiency.

Filter: Since the water may carry impurities and particulate matter, a filter is required inside the pipe to prevent these impurities from clogging the drip holes. The design of the filter needs to take into account the filtration effect and resistance to ensure the cleanliness of the water without affecting the smooth flow of water.

Pipe wall thickness and material selection: Pipe wall thickness and material selection are directly related to the strength and durability of the pipe. In the design, appropriate materials need to be selected according to specific application scenarios, and the smoothness of the internal and external surfaces of the pipe must be taken into consideration to reduce the resistance of the water flow.
