Abstract

Superheaters play an important role in converting saturated steam to the point of superheating. The condition of the superheater needs to be considered, if there is rust it will reduce the performance of the superheater in heating steam to the point of superheat. Rust / corrosion is the enemy of dangerous metals. Corrosion is defined as a deterioration in the quality of metals due to electrochemical reactions with their environment In corrosion events, metals undergo oxidation, while oxygen (air) undergoes reduction. The corrosion event itself is an electrochemical process, which is a process (change / chemical reaction) that involves electricity. Certain parts of the metal act as the negative pole (negative electrode, anode), while the other part acts as the positive pole (positive electrode, cathode). Electrons flow from the anode to the cathode, resulting in corrosion. By calculating the corrosion rate of superheaters with material A-213 T22 can be a consideration for using materials that are more resistant to rust or become a consideration in estimating repair time.

Abstract

Centrifugal pumps are widely used in industries for fluid transfer, operating on the rotation of an impeller driven by a prime mover. However, sudden performance drops and operational instability pose significant challenges, impacting overall system efficiency. Predictive maintenance relies on vibration analysis to assess rotating equipment condition, with vibration patterns indicating potential issues such as cavitation and corrosion. Prolonged cavitation leads to erosion of channel wall surfaces, resulting in structural damage. This study aims to address the knowledge gap in understanding the relationship between pump vibration, cavitation, and corrosion. Through comprehensive vibration analysis and examination of pump performance, our research identifies the mechanisms driving pump degradation. The findings highlight the critical role of predictive maintenance in mitigating pump failures and optimizing system performance. Highlights : Vibration analysis crucial for predictive maintenance: Identifying early signs of pump deterioration. Cavitation-induced erosion: Understanding the impact of prolonged cavitation on pump performance. Importance of proactive maintenance: Mitigating pump failures and optimizing system efficiency. Keywords : Centrifugal pumps, Vibration analysis, Cavitation, Corrosion, Predictive maintenance

Abstract

This study investigates the predictive potential of specific vibration patterns in assessing the structural integrity of centrifugal pumps, vital for industrial fluid transport. Despite their importance, these pumps often encounter performance issues attributed to vibration-related damage such as cavitation and corrosion. Addressing this gap, we employ advanced vibration analysis techniques to identify distinct signatures indicative of cavitation and corrosion progression. Our research aims to provide an early detection tool for maintenance by understanding these patterns. Through our method, we reveal significant correlations between vibration patterns and pump condition, offering implications for extending pump lifespan and enhancing maintenance strategies in industries reliant on such machinery. Highlights: Centrifugal Pump Operation: Impeller rotation transfers fluid. Vibration Analysis Significance: Essential for predictive maintenance. Cavitation and Corrosion Effects: Trigger vibration, erode surfaces. Keywords: Centrifugal Pump, Corrosion, Vibration

Abstract

Penelitian ini membahas tentang pembuatan bagian pelengkap mesin bubut untuk meningkatkan efisiensi waktu dan kekasaran produk dalam proses pemotongan benda kerja. Maka dalam penelitian ini dibuat alat berupa Spring Parting Tool Holder. Dalam pembuatan alat ini digunakan plat ST 42 sebagai bahan utama. Proses pembuatan komponen meliputi: proses frais dan proses drilling. Sebelum ke tahap pembuatan alat, perencanaan desain gambar dibuat menggunakan Solidwoks agar keseluruhan model menjadi jelas dan siap untuk proses manufaktur pembuatan alat. Secara teoritis, total waktu yang dibutuhkan untuk pengerjaan pembuatan alat adalah 5 Menit 14 Detik, namun waktu pengerjaan alat secara aktual adalah 25 Menit 38 Detik. Hal ini terjadi karena dalam kondisi aktual pemakanan dari benda kerja dilakukan secara berurutan, selain itu proses drilling yang masih manual dan tekanan yang tidak selalu sama.

Abstract

Drying is the heating process of food so that it reaches the water content of a certain material. This study aims to determine the drying rate and drying efficiency of wet crackers by using a dryer that is varied with variations in temperature and air velocity. The drying rate is the rate at which the water content of the specimen is reduced. In the drying rate test, it is obtained from the rate of reduction of the mass of the specimen due to evaporation of the water content in the specimen. The test was carried out in stages by adjusting the temperature to 60oC, 70oC, and 80oC with the air speed of the blower at 700 rpm, 1150 rpm, and 1600 rpm continuously. The test results show that the drying rate and drying efficiency are the most optimal as follows: a temperature of 80oC at a blower speed of 700 rpm produces a drying rate of 11.67 mg/min.
