Science of Soil, Irrigation and Mechanization, Volume 1,No. 2-3: 29-37, 1991, Cuba.
The MAR-90 Z sprinkler is produced in Cuba since 1977 by the Sprinkler Irrigation Enterprise José Luis Tassende belonging to SIME. In the process of recuperation of the hydraulic will, which is currently in the country, has emerged the problem of inadequate quality of sprinklers in the national production, so in this paper assesses the use of this sprinkler.
Under laboratory conditions the life of the sprinkler MAR-90 Z to determine the impact of intensive farming in some of its technical indicators was studied. The scheme of work that was submitted to the sprinkler influenced in its rotation speed of 0.29 rpm for 1000 hours of operation, which decreased to 0.17 rpm to 3000 hours; we also observed a very little wear and acceptable duration of apparatus.
