The manufacturer of Venturi Fertilizer For Agriculture Irrigation tells you that the fertilizer applicator is one of the important parts of the micro-irrigation system and is usually placed in the first part of the irrigation system for fertilization.

The manufacturer of Venturi Fertilizer For Agriculture Irrigation tells you that the commonly used fertilizer applicators include differential pressure fertilizer tanks, Venturi fertilizer applicators, and hydraulically driven fertilizer injection pumps. Among them, the venturi fertiliser applicator has the characteristics of low cost, convenient use, stable fertilization concentration, and no need for external power. It is widely used in facility agriculture.
The manufacturer of Venturi Fertilizer For Agriculture Irrigation tells you that due to various reasons such as the hardware of the Venturi fertilizer applicator and the improper use of the technicians, the fertilizer applicator often does not absorb fertilizer or the water flows back into the fertilizer bucket, which seriously affects the use effect. This article addresses this problem. Analyze the causes and provide corresponding countermeasures for the reference of field technicians.
The main reasons and countermeasures for the phenomenon that the venturi fertilizer applicator does not absorb fertilizer or the water flows back into the fertilizer bucket are as follows:
First, the fertilizer applicator was installed incorrectly. The manufacturer of Venturi Fertilizer For Agriculture Irrigation tells you that when there is no fertilizer absorption, the technician should first check the installation direction of the fertilizer applicator and whether the direction of the water inlet and outlet is installed reversely.
Second, the manufacturer of Venturi Fertilizer For Agriculture Irrigation tells you that the flow rate is too small, and 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. You can try to clean the filter, add more drip irrigation tapes and other measures.
Third, the pressure is not enough. The manufacturer of Venturi Fertilizer For Agriculture Irrigation tells you that the general inlet pressure should reach 0.15Mpa, and the inlet and outlet pressure difference should reach 0.1Mpa to absorb fertilizer. Pressure measures such as adding a pressure pump can be adopted.
