Abstract

The water wheel is defined as a mechanical device in the form of a wheel with blades (buckets or spatulas) around the edges which are on the horizontal axis of water as the working fluid. The water flowing into and out of the wheel has no excess pressure, only atmospheric pressure. The speed of the water flowing into the wheel must be large, because if the speed is large, the impetus on the blades of the water wheel will be greater. Comparison of the Effect of Natural Flow Performance and the Use of Sluice Gate on the Wheel. The use of Sluice Gate on the Waterwheel affects the performance of the waterwheel and from several variations in the width of the sluice gate flow gap (25mm), (35mm), and (40mm) with a sluice gate flow gap of 40 mm with an efficiency of 38.12 % at 40 rpm rotation, which is 13 Watt higher than the natural flow test at 40 rpm, the rotation speed is 5.11 watts with an efficiency of 10%, and the lowest power at 10 rpm is 3 watts and an efficiency of 6% with a discharge of 12 liters per second.

Abstract

The hydraulic system is an energy transmission system utilizing liquid fluids. Liquids possess a characteristic different from solids in their inability to withstand shear stress. The employed methodology is qualitative research, also referred to as naturalistic qualitative research, which entails a natural implementation without manipulating circumstances. This study aims to identify the causes of damage to the hydraulic system in the press section machine, along with implementing appropriate corrective measures, while examining the hydraulic functioning of the press section machine. The research problem specifically focuses on analyzing the damage to the hydraulic cylinder and addressing cylinder seal failure. The damage results from seal wrinkling caused by aging, heat and wear. It is important to ensure that the hydrostatic test pressure is carried out at pressures up to 20 MPa with a holding time of at least 30 seconds. This examination ensures that the hydraulic roll press problem has been fully resolved and will not reoccur. Hydraulic systems offer numerous advantages as an energy source in various applications. These advantages include their lightweight nature, ease of installation, and low maintenance requirements. Inadequate performance in the hydraulic roller pressure section is attributed to a hydraulic cylinder seal that does not meet the specified standards, necessitating replacement with a suitable seal.
