Abstract

Abstract The present paper is concerned with experimental study of performance of a vertical axis savonius wind turbine. Savonius turbine blades are made of PVC pipe and a fan to drive the turbine. The test was carried out with a different number of blades, namely 2 blades, 3 blades and 4 blades at air velocity of 3.6 m/s, 4.4 m/s and 5.8 m/s. The results obtained the highest maximum power efficiency is in the 3 blade test, namely at air velocity of 3.6 m/s of 0.156, air velocity of 4.4 m/s of 0.313 and air velocity of 5.8 m/s of 0.182. The maximum torque coefficient for the three air velocity also obtained the highest value in the 3 blade test. At a air velocity of 3.6 m/s, a torque coefficient of 0.641 is obtained, a air velocity of 4.4 m / s is 1.027 and a air velocity of 5.8 m/s is 0.745. The maximum efficiency in the 3 blades test with air velocities of 3.6 m/s, 4.4 m/s, and 5.8 m/s is obtained respectively 15.6%, 31.3% and 18.2% efficiency. In conclusion, the 3 blades wind turbine has the highest efficiency compared to the 2 and 4 blades tests. Meanwhile, the highest efficiency was obtained at a air velocity of 4.4 m / s with 3 blades, namely 31.3%.

Abstract

Conveyor belt planning with a capacity of 6 tonnes / hour with a carrying distance of 12m and a slope angle of 200 for a rubber factory. The belt serves as a medium for transporting rubber raw materials, where the planned belt width is (L = 800mm) and the overall length (Ls = 24m) Where the conveyor belt is driven by a pulley whose width is 900 mm, the diameter of the pulley is (Dp = 625 mm), the driving pulley rotation (n = 24.45 rpm), the electric motor as the initial drive for moving the conveyor belt machine to move the pully is used a motor with torsional moment (T = 12906 kg / m), where the shaft material is taken from JlS steel. G. 4501. S. 45. C. Tensile stress 58 kg / mm2. Roll diameter (D = 108), the bearings used are closed type ball bearings with bearing number (6008), inner diameter (d = 40 mm), outer diameter (D = 68 mm), bearing width (B = 15 mm), Specific dynamic nominal capacity (C = 1310 kg), static nominal capacity (Co = 1010 kg).
