Abstract (en)
THROUGH 20 YEARS OF PERSONAL EXPERIENCE IN THE FIELD OF IRRIGATION IN MEXICO, I HAVE OBSERVED THAT THE IN TRADITIONAL WAYS OF MANUFACTURING ELECTROMECHANICAL EQUIPMENT (FLOODGATES AND MECHANISMS AMONG OTHERS) FOR IRRIGATION SYSTEMS STRUCTURAL STEEL IS COMMONLY USED, BRONZE AND CAST IRON WHICH IS THEN MACHINED TO GIVE IT ITS FINAL SHAPE. THE EQUIPMENT UNDERGOES ANTICORROSIVE AND LUBRICATING TREATMENTS. MY IDEA IS TO ELIMINATE TO A GREAT DEGREE, THE SERIOUS PROBLEMS IN: DESIGN, OPERATION, MAINTENANCE, AND USEFUL LIFE GIVEN THE HIGH DEGREE OF DETERIORATION THAT THEY PRESENT, CAUSED BY SEWAGE, WASTE, WATER WITH A HIGH ALKALINE CONTENT, ETC. AS A RESULT OF A LOT OF RESEARCH I HAVE DEVELOPED, TESTED, AND RE-TESTED ARRANGEMENTS WHICH ARE A COMBINATION OF SIMPLIFIED MACHININGS AND/OR MOLDINGS WHICH ADDED TO THE SIMPLICITY OF MY DESIGNS AND THE MATERIAL USED (NYLON, POLYPROPILENE, ULTRA-HIGH MOLECULAR WEIGHT POLYETHILENE, HIGH-DENSITY POLYETHILENE, AND PVC) ARE THE IDEAL SOLUTION. MAIN FEATURES: SIMPLICITY OF DESIGN EASY INSTALLATION NO LUBRICATION NO MAINTENANCE EASY OPERATION ECOLOGICAL NO SEALS LONGER USEFUL LIFE NO WASTE <IMAGE>
