What is an integral dripper?
Integral drippers are invisible. Coming out of the factory they are well hidden inside the drip irrigation pipe. Only the small outlet holes are visible from the outside. However, also invisible, they can be felt through the pipe wall, hard elements in the softer, flexible material of the pipe. Normally you can find them positioned in same distance along the pipe.
drippers make a critical role in efficient irrigation system. As the pipe is pressurized, Drippers maintain the uniform, constant flow, of water as it come out of the pipe. Unlike a simple perforation in a pressured pipe that will induce a jet of water, the dripper is to create a relaxed, constant, and controlled drip that. Even with numerous drippers in the field, all the drippers will emit almost same amount of water, securing the uniformity of the crop.
Pressure compensated drippers (PC) are equipped with a special mechanism that regulate the discharge of the drippers. When the pressure rise, the flow does not increase accordingly. Instead, a compensation mechanism regulate the flow and maintain it constant. In steep topography, this mechanism maintain uniform flow regardless of the drippers position in the hill. In long driplines laterals, this mechanism secure uniform flow rate regardless of drippers distance from the initial, although the pressure drops along the line.
As aforementioned, irrigation drippers are divided into two main types:
PC Drippers (Flow Regulated): Equipped with a labyrinth and diaphragm that maintain a constant flow rate even when the pressure in the pipe fluctuates. It has a consistent, steady flow that fits long driplines. It is ideal for long, mechanized fields to ensure the growth is equal throughout large pieces of land.
Non-PC Drippers: Equipped with a labyrinth that controls the output by forcing a turbulent flow. The flow is synced with the pressure, so it changes significantly throughout the irrigation line and, from high-pressure flow at the start of the line to low pressure at the end of it. It is suitable for flat surfaces and short stretches, mainly for growing different crops.
