The Venturi Fertilizer For Agriculture Irrigation company said that the fertilizer applicator is one of the important components of the micro-irrigation system and is usually placed at the head of the irrigation system for fertilization. The Venturi Fertilizer For Agriculture Irrigation company found that the commonly used fertilizer applicators are pressure differential fertilizer applicator, Venturi fertilizer applicator and hydraulic driven fertilizer injection pump. Among them, the Venturi fertilizer applicator has the characteristics of low cost, convenient use, stable fertilization concentration and no need for external power, and is widely used in facility agriculture. However, the Venturi Fertilizer For Agriculture Irrigation company found that due to various reasons such as the hardware of the Venturi fertilizer applicator and the improper use of technicians, the fertilizer applicator often did not absorb fertilizer or the water flowed back into the fertilizer bucket, which seriously affected the use effect.

The Venturi Fertilizer For Agriculture Irrigation company analyzes the cause of this problem and provides corresponding countermeasures for the reference of technical personnel.
Venturi Fertilizer For Agriculture Irrigation company shares the reasons and countermeasures of Venturi fertilizer applicator not sucking fertilizer：
First, the fertilizer applicator was installed incorrectly. When the phenomenon of non-absorbing fertilizer occurs, the Venturi Fertilizer For Agriculture Irrigation company recommends that the technicians first check the installation direction of the fertilizer applicator and whether the direction of the water inlet and outlet is reversed. Second, the flow rate is too small, the flow velocity at the throat section is small, it is difficult to generate enough negative pressure or vacuum, and the fertilizer absorption effect is not ideal. The Venturi Fertilizer For Agriculture Irrigation company suggests that you can try to clean the filter and increase the number of drip irrigation tapes appropriately. Third, the pressure is not enough. Generally, the water inlet pressure should reach 0.15Mpa, and the pressure difference between the inlet and outlet should reach 0.1Mpa to absorb fertilizer. Pressurization measures such as adding a pressurizing pump can be used.
