The PE irrigation hose is the lowest part of the entire drip irrigation system and is also the part that is in direct contact with the crop. The water-saving irrigation equipment on the market is varied, but the reasons for the blockage are basically the same. As a professional manufacturer of drip irrigation equipment, we will explain the reasons for the blockage of the drip irrigation pipe of PE drip irrigation pipe and the solution.
1, physical blockage
Drip irrigation tube debris is physically blocked. Due to the vastness of our country, the environment in which water-saving irrigation systems are used is also complicated. In some water sources, the water quality is not good, and the filtration system is not good enough. The debris in the water source can easily enter the branch pipeline through the filtration system. The drip irrigation tube will eventually become stuck in the serrated flow path in the drip irrigation belt of the inlaid patch, causing the drip irrigation tube to be blocked.
Since it is a source of water, of course, it must be intercepted at the water source. Add several anti-fouling iron fences at the water intake of the pump. The number of fences is small to large, graded and filtered, 10-60, and the suspended silt is removed. Sundries.
Or take the water first to the reservoir, and then use it after natural sedimentation. Pay attention to avoiding light to prevent other debris from entering, and also inhibit algae reproduction. In the next step, according to the water quality after sedimentation, sand filter, mesh filter, laminated filter, etc. can be installed for filtration treatment. After pre-filtration treatment, the water quality can be greatly improved.
2, chemical blockage
The drip irrigation tube is blocked by chemical deposits. At present, China’s most water-saving irrigation system generally has an integrated distribution of water and fertilizer, and some fertilizers are insoluble in water. After being left in the drip irrigation tube, a precipitate similar to calcium sulfate is produced, and the drip channel is blocked.
Proper use of drip fertigation. Try to use soluble fertilizer, and the fertilizer applicator must be installed before the filter. The drip irrigation system can be fertilized normally after the filtration equipment is finished. After the fertilization is finished, the system should be rinsed with water for about 5 minutes to prevent the remaining fertilizer in the pipeline from being precipitated.
3, biological blockage
The pe drip irrigation tube is biologically blocked. If a subsurface drip irrigation pipe is used, the water repellency of the plant roots and the uneven permeability will cause the roots of the plants to grow to the outlet of the drip irrigation pipe, and then protrude into the water outlet hole to cause blockage. In addition, if the water quality is rich in algae, the drip irrigation system of the fertilizer pool begins to be insufficient. In addition to the nutrientization of the fertilizer, it is easy to cause the microbes to multiply, and finally the inner wall of the drip irrigation tube can be covered and blocked.
When the pe drip irrigation pipe is installed on the ground, the water outlet hole on the drip irrigation pipe faces upward, so that a small amount of impurities in the water can be deposited at the bottom of the pipe, and the root system can be prevented from intruding into the drip irrigation hole. The underground drip irrigation tube can kill the root system near the water outlet by injecting a proper concentration of chlorine gas, but the concentration should be controlled. For the algae biology class, use acid solution such as chloric acid, nitric acid or sulfuric acid to clean. When using, the PH value should be controlled at 5.5-6.0. The same acid concentration should be strictly controlled. Rinse with water after the end.
4. Water quality scaling is blocked:
The pe drip irrigation tube is obstructed by water sediment. Most of the irrigation water in the northern region is water from rivers, rivers, lakes, springs and streams. The water is soluble in calcium and magnesium compounds. It is hard water. Long-term use of the inner wall of the drip irrigation pipe will produce more carbonate and block the dripper.
A small flow screen filter can be installed behind the shed valve for secondary filtration treatment, which can greatly improve the safety performance of the drip irrigation system.
Summary of the summary:
All the dripper anti-blocking capabilities in the water-saving irrigation system are limited. To avoid clogging as much as possible, it is necessary to prevent thinking that is greater than governance. For example, regularly rinse the drip irrigation tube and clean the filter. Yunxi Rubber and Plastic Irrigation reminds you that when the newly installed drip irrigation pipe is used for the first time, it is necessary to open the plug at the end of the drip irrigation pipe, rinse the water with the brake, and rinse the impurities in the pipe before starting to use. The drip irrigation is generally used 5 times. Rinse again.
Always check the filter before filling, open the filter backwashing device to remove the impurities, remove the impurities accumulated on the filter screen in time, prevent the filter from clogging, and find that the filter is damaged in time.
The stricter the pretreatment, the less likely the drip irrigation tube will become blocked.
