Everyone should be very familiar with the steel mesh composite pipe. The steel mesh composite pipe is used in many areas of water pipe. Although the function of the pipe is very good, various problems often occur in the application process. If there is blockage in the application, affecting the normal operation, and there is a certain amount of pipe loss, let us understand the reason for the blockage of the steel mesh composite pipe.
Physical blocking is the main reason for the blocking of steel mesh composite pipe. The water quality is poor and the filtration system is imperfect. When sand and other sundries are pumped into the pipeline and composite pipe, these sundries will block the flow channel, making the drip irrigation head unable to discharge water when passing through the zigzag flow channel of the embedded drip irrigation head.
Biological blockage refers to the blockage caused by the intrusion of crop roots into drip irrigation holes or the growth of algae and other microorganisms in irrigation water. If the irrigation water is rich in algae and other organisms, the steel mesh composite pipe system is often combined with fertilizer irrigation. The light protection equipment such as fertilizer pool is not in place, which simply forms a lot of microbial reproduction, covering and blocking the inner wall of the pipe. The water content of crop roots and unbalanced irrigation will cause roots to grow to the outlet of drip irrigation, and then extend to the outlet, forming a blockage.
Sediment blockage is mainly caused by fertilizer and precipitation. 1、 Some fertilizers left in the steel mesh composite pipe after drip irrigation will deposit, such as calcium sulfate, blocking the flow channel of drip irrigation head. 2、 If the water is hard water with high carbonate content, long-term use will cause more scale on the inner wall of drip irrigation pipe, blocking the drip irrigation head. In addition, the composite pipe itself has high requirements for irrigation water quality, such as system planning shortcomings or improper use, which simply causes pipe system blockage, and needs to be paid enough attention.
