Choosing A Emitter, These 5 Elements are Very Important

When choosing a dripper, pay more attention to the flow rate, working pressure and scope of the dripper. The selection of these parameters should rely on a reasonable irrigation system, comprehensive crops, planting patterns, and soil quality.

So for the dripper itself, we should also consider the following aspects when choosing:

1. The manufacturing accuracy of the dripper. The uniformity of drip irrigation is closely related to the accuracy of the dripper. In many cases, the flow change caused by the manufacturing deviation of the dripper exceeds the flow change caused by hydraulics. The dripper with insufficient precision will seriously affect the uniformity of irrigation. Choose drippers with well-manufactured and guaranteed quality.

2. Sensitivity to temperature changes. In areas with large temperature changes, a turbulent irrigator should be used. The size and performance of certain parts of the irrigator are easily affected by the water temperature. For example, the elasticity of the artificial rubber sheet used in the pressure-compensated dripper may vary with the water temperature. , Thereby affecting the flow rate of the dripper.

3. Ability to resist blockage, siltation and precipitation. Drippers with poor anti-clogging capabilities require high-precision filtration systems, which often result in a substantial increase in the cost and energy consumption of the drip irrigation system, and even lead to the scrap irrigation project. The dripper with strong anti-clogging ability can avoid the accumulation of clogging caused by repeated use of drip irrigation pipes.

4. Price and comprehensive cost. There are many aspects to consider when considering cost. The price of the dripper is determined by factors such as material, process, output, etc. When installing, using and maintaining, it is necessary to consider factors such as installation man-hours, difficulty, and accessories. The overall cost of the dripper and the system should be measured. For example, the dripper is cheap. However, if the types of pipes and connectors are small and the price is high, it is often impossible to save money in the end.

5. Service life. The service life of the dripper is closely related to its structure, material, installation and usage. According to the growth cycle and planting plan of the crop, the dripper with better cost performance can be selected.
