Why is the nozzle blocked in the integrated irrigation system of water and fertilizer?
The integrated irrigation system of water and fertilizer is more and more widely used in modern agriculture, which not only saves manpower, but also improves the efficiency and accuracy of irrigation. However, the problem of nozzle blockage often plagues agricultural producers, so what are the causes of Irrigation system? Let's find out.
First, the most common problem is the clogging of the filter. The function of the filter is to screen the impurities in the water and ensure the cleanliness of the water quality. Once the filter is blocked, its own water loss will increase, which will cause the pressure difference between the front and back of the filter to increase, resulting in a decrease in the outlet pressure of the nozzle. In this case, the spray effect of the nozzle will naturally be affected, and in serious cases, the nozzle at the end of the system may even be completely out of water. The solution to such problems is relatively simple - clean the filter regularly, and if the situation is more serious, then you need to manually perform a thorough cleaning.
Second, the problem may stem from the pH of the water source. If the irrigation system water source is alkaline and the pH value is maintained between 7-8 for a long time, the small holes inside the sprinkler head will gradually form a hard scab after long-term irrigation. Over time, this crust will build up until the nozzle is blocked. Once this happens, it is often only possible to replace the nozzle. Therefore, in order to avoid problems, the pH value of irrigation system water should be regularly tested and controlled at a neutral level as far as possible.
Finally, the problem may lie in the configuration of the filter. Some systems only install sand filters or only install laminated filters, and do not use two-stage filtration. For well water, a single laminated filter is sufficient. However, for surface water, in order to ensure water quality, it is best to combine sand filter and laminated filter. If such a configuration is not done, the filtering effect will be greatly reduced, and eventually lead to blockage of the nozzle.
In addition, we can also take some measures to prevent the blockage of the nozzle
1. Strengthen the cleaning and maintenance of the filter. For filters, regular cleaning is the key to maintaining the normal operation of the sprinkler irrigation system. In addition, the selection of filters is also very critical, and the appropriate filter type and filtration accuracy need to be selected according to the specific situation of the water source.
2. For the blockage of the nozzle caused by alkaline water source, we can prevent it by adjusting the pH value of the water source. Before irrigation, the water can be treated with an appropriate amount of acidification to reduce the deposition of alkaline substances in the water, and the nozzle is checked and cleaned regularly.
3. As for the configuration of the filter, we need to choose the appropriate filter system according to the actual situation. If surface water is used, a two-stage filtration combination of sand and gravel filters and laminated filters should be considered to ensure clean water quality, thereby preventing nozzle blockage.
Although the problem of nozzle blockage in water-fertilizer integrated sprinkler irrigation system is very common, most of the problems can be avoided through scientific and reasonable prevention and maintenance measures. Maintaining the normal operation of the irrigation system not only ensures the uniform irrigation of crops, but also improves the utilization rate of water and fertilizer.
