Using the performance chart provided by Mazzei allows for accurate planning and engineering of your ozone system. However, a proper understanding of this performance chart is necessary.<\/p>\n\n\n\n<figure class=\"wp-block-image is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.oxidationtech.com\/media\/wysiwyg\/O3_solubility\/How_a_venturi_works_image.png\" alt=\"Mazzei Venturi Injector for ozone\" width=\"262\" height=\"112\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Below is a chart for a common venturi injector. The injector is capable of mixing both liquid and gas into the main water flow through the venturi injector. For the purpose of dissolving ozone gas into water, the 3<sup>rd<\/sup> and 4<sup>th<\/sup> columns can be ignored completely as these refer to liquid suction only.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The first column is the injector inlet pressure, which is the pressure provided to the venturi injector inlet. The 2<sup>nd<\/sup> column is the injector outlet pressure, which is the pressure exerted on the injector outlet from delivering the water to the point of use. The 3rd column called MOTIVE FLOW states the flowrate of water going through the injector based on inlet\/outlet pressures. This is what allows the proper pump to be chosen, calculate gas to liquid ratios and more. The last column called AIR SUCTION lists the amount of gas (oxygen,ozone, air), that can be sucked into the water stream at these aligned injector inlet\/outlet pressures. As can be seen from the chart, as injector outlet pressure (2) increases, injector suction decreases (4). This is true even though the motive flow (3) stays relatively constant.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>&nbsp;<\/strong><img loading=\"lazy\" decoding=\"async\" width=\"364\" height=\"748\" src=\"https:\/\/www.oxidationtech.com\/media\/wysiwyg\/O3_solubility\/Venturi_Injector_Performance_Chart.png\" alt=\"How to read a Venturi Injector performance chart\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.oxidationtech.com\/ozone\/solubility\/how-to-read-a-venturi-injector-performance-chart.html\">Read full and original article HERE<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.oxidationtech.com\/ozone\/solubility\/fundementals-of-ozone-solubility.html\">Learn more about ozone solubility HERE<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.oxidationtech.com\/ozone\/solubility\/ozone-dissolved-with-venturi-injector.html\">Learn more about ozone venturis HERE<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.oxidationtech.com\/products\/accessories\/ozone-injection\/ozone-venturi.html\">Purchase venturi injectors HERE<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Read the original and full article HERE The Mazzei Venturi Injector is incredibly predictable and reliable in the performance of liquid flow and gas suction.
