The drive requires a high reduction ratio for very low output speed, high torque to move the towers and sprinkler pipeline, and resistance to outdoor conditions. Irrigation reducers commonly use worm or helical gearing with protection against water and dust ingress.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Reference Centre Pivot Irrigation Drive Specifications<\/h1>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><td><strong>Parameter<\/strong><\/td><td><strong>Typical value<\/strong><\/td><\/tr><\/thead><tbody><tr><td>Torque capacity<\/td><td>Approx. 1130 N\u00b7m (10,000 lb-in)<\/td><\/tr><tr><td>Gear ratio<\/td><td>20:1, 30:1, 40:1<\/td><\/tr><tr><td>Input speed<\/td><td>1740 rpm<\/td><\/tr><tr><td>Output speed<\/td><td>43\u201387 rpm<\/td><\/tr><tr><td>Efficiency<\/td><td>90%<\/td><\/tr><tr><td>Housing material<\/td><td>Precision die-cast aluminium for heat dissipation and corrosion resistance<\/td><\/tr><tr><td>Sealing<\/td><td>Triple-seal design<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h1 class=\"wp-block-heading\">Drive Characteristics of Hose Reel Irrigators<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Hose reel irrigators use a gear reducer to rewind the polyethylene (PE) hose. Resistance to back-driving is relevant to preventing unintended reel reversal when input power stops. During retrieval, terrain changes can cause load fluctuations, so the reducer also requires suitable overload capacity.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Irrigation Applications in the Middle East and Africa<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Agricultural areas in Egypt\u2019s Nile Delta, oasis farming in Saudi Arabia and irrigation projects in Kenya create continuing demand for reliable equipment. SANYOO\u2019s irrigation products are designed for agricultural duty, with optimised sealing and corrosion protection. Material selection and sealing address both water ingress in rainy tropical climates and dust-related wear in sandy environments in the Middle East.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Discuss Your Irrigation Equipment Project<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Visit www.sanyoogear.com and provide the irrigation system type, required wheel or reel torque and speed, electrical supply and environmental conditions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Drive Requirements for Centre Pivot Irrigation Centre pivot irrigation systems use gear reducers to drive the tower wheels, moving the irrigation structure slowly around a central pivot.
