Our Technology

Technical Specification

Pressure :< 3 psi

Flow rate :< 0.2 L/H

Self-cleaning irrigation technology enables low-pressure, low-flow irrigation with a pressure of 0.3-2 psi flow rate of 20-150 ml/h due to its superb self-cleaning and anti-clogging functions.

With the same length and spacing as drip irrigation, tube diameter is less than 4 mm or 1/6 of an inch. Not only will the production costs be significantly reduced, but the uses will also be more extensive. 

Background


The labyrinth flow channel design of drip irrigation is traditionally considered the best low flow irrigation solution for blockage resistance. After 30 years of development, the best drip irrigation can now only achieve flow rates down to about 600ml/h at 1 bar pressure, but the filtration requirements are extremely high, and the system is risky. It cannot recover once it is clogged, and the system must be scrapped. Our emitters can operate at pressures near 0.2 bar and flow rates lower than 200ml/hour. It requires no filtration and it is anti-clogging and recoverable . There is no product in the world can achieve these specifications.


For a long time, this emitter design has dominated micro-irrigation. It uses a convoluted flow path to reduce flow rate and generate turbulence to remove impurities in the flow channel to reduce the probability of clogging, while still maintaining uniform irrigation. The emitter's miniaturization under the premise of uniform flow is the basis of efficient water-saving irrigation, while the anti-clogging performance is the fundamental guarantee of uniformity of irrigation. However, small flow rate and anti-clogging performance are mutually conflicting goals because as flow rate decreases, particle accumulation increases leading to increased clogging susceptibility. If lower flow rates are to be achieved, it will be necessary to 1. Make the flow channel narrower, if the increased cost of mold machining accuracy and production precision can be tolerated. 2. Lengthen the channel if the consequences of larger emitters can be tolerated. 3. Reduce the water supply pressure. All these measures will face a problem, as the flow rate decreases, the turbulence generated by the labyrinth flow channel will become weaker and weaker, and eventually the impurities in the flow channel cannot be cleaned and poor irrigation uniformity or blockage occurs. In particular, once the emitter is clogged, it is difficult to recover, leading to scrap. In order to be safe, the typical working pressure of the conventional emitter that can be seen on the market is in the range of 0.5-1 bar, and the flow rate is mainly in the range of 1-2 liters/hour.


The last half century has been a period of great explosion of human technological achievements, but the terminal control of water in the field of micro-irrigation has never changed significantly and has always been the labyrinth flow pattern. Since water flow is different from the flow of electrons, there are very few options available for precision control of water.


The self-cleaning irrigation emitter is a new technological innovation that uses topological space design to achieve high level resistance to blockage in small spaces. This special material structure can make the flow channel infinitely close to the size of the particles and can ensure the continuity and stability of the space when the particles are passed through. Even microorganisms cannot attach to it. At the same time, it can ensure that any disorderly solid particles can become the continuation of the orderly space after entering this space field, until moving out of this space field, to achieve perfect anti-clogging. Not only is it more water and energy-efficient, but the new emitter can also be made smaller. With its low flow rate, the irrigation pipe containing the emitter can be made extremely thin, laying the foundation for further reduction of micro-irrigation pipe costs in the future.
