Injector type Venturi<\/strong><\/p>\n It is a tube with tapers on both sides, working on the principle of pressure drop. It is made of polymer materials resistant to aggressive media. The injector is installed in the system on the fertilizer head, which allows you to separate the irrigation and fertigation processes (application of fertilizers and chemicals with irrigation water).<\/p>\n The flow passing through the injector creates a negative pressure (vacuum), which draws the chemical solution into the channel, where it mixes with the passing water and is introduced into the system.<\/p>\n When installing the injector, pay attention to the direction of the arrow. For normal operation, the pressure at the inlet to the injector must be at least 2 Atm, the minimum volume of water passing through the injector should be 0.7 m3 \/ h for the 3\/4 “model and 3 m3 \/ h for model 1”. The more the valve on the fertilizer head is covered, the higher the pressure drop, and, correspondingly, the intensity of intake of the injector. The “Venturi” type injector gives a relatively good uniformity of mixing the mother liquor with the main water flow, and maintains the preset concentration throughout the time of the solution injection.<\/p>\n Fertilizer capacity<\/strong><\/p>\n It is a hermetically sealed tank, which has cranes at the inlet and outlet. It serves to simplify the introduction of mineral fertilizers and other chemicals through a drip irrigation system. A small pressure drop created by the tap of the fertilizer head creates a parallel flow through the tank where water mixes with the substance and transfers it to the system. Fertilizer capacity is the most reliable and least fanciful in use. Its only drawback is the uneven concentration of the mother liquor. The solution entering the system initially has a high concentration, then it gradually decreases<\/p>\n![\"\"](\"http:\/\/agroex.com.ua\/wp-content\/uploads\/2018\/02\/2-plain-ventury-assembly1-300x300.jpg\")

<\/a>It is used for applying fertilizers and plant protection products through irrigation systems and guarantees high accuracy of their dosing. The device is mounted directly into the irrigation system, directly or through the fertilizer head. The working turbine is driven by water pressure in the system, (without electricity), as a result of which the dispenser draws a strictly defined amount of solution from the container, a homogeneous mixture is formed in the mixing chamber with water, which is fed further. The dispenser can be adjusted only once. Re-installation and external monitoring, it does not require. The amount of intake solution is constant and strictly proportional to the amount of water flow, regardless of the pressure, and therefore there is no risk of overdosing.
