What the principle of venturi fertilizer injector?
The Venturi fertilizer injector and micro-irrigation system are installed parallel to the water supply pipe control valve at the entrance to the irrigation area. When the control valve closes, a pressure difference is created, causing water to flow through the venturi fertilizer injector. This flow creates a vacuum in the venturi tube, drawing the fertilizer solution from the open bucket into the pipe system for fertilization.
Venturi fertiliser injector has a low cost, easy to use, stable concentration of fertiliser, without the need for additional power, etc., the disadvantage is that the pressure loss is larger, generally suitable for irrigation area is not large occasions. Thin-walled porous tube micro-irrigation system working pressure is low, you can use the venturi fertiliser injector.
Advantage;
1、Venturi fertiliser injector is installed in parallel with the water supply control valve at the entrance of the irrigation area of the irrigation system, when used, the control valve will be closed down, forming the pressure difference before and after the control valve, which can make your dissolved fertiliser in water inhaled into the venturi fertiliser injector and then flow into the water supply pipeline.
2、Using the vacuum suction force generated by the water flow through the venturi, the fertiliser solution will be evenly sucked into the pipeline system from the open fertiliser drum for fertiliser application, making your operation more convenient and simple.
3、If the concentration of fertiliser is stable, there is no need for additional power, which saves your time and resources.
4, according to the crop and irrigation area to select the appropriate size of the fertiliser applicator, too large or too small are not conducive to effective fertiliser application.
5, such as can not be determined, select the relevant specifications of the small and then with the fertiliser kit with the main pipeline installed in parallel by adjusting the valve to control the amount of water to achieve the purpose of fertiliser injection: if you determine that the boiler is too small can be adjusted through the valve to prolong the time to achieve the purpose of fertiliser.
6. Install the fertiliser applicator in parallel in the pipeline.
7, the water flow should be consistent with the direction of the arrow on the fertiliser applicator, otherwise it will not work properly. The ball valve on the main pipe should be able to make tiny adjustments so as to achieve the proper working condition. When installing, make sure that there is no air leakage in the connection part, otherwise it will affect the normal working of the fertiliser applicator.
