Abstract

OGAWA SEIKI cavitation phenomenon experimental equipment merupakan salah satu peralatan pengujian sistem perpipaan dengan permodelan kavitasi yang dapat dijumpai di Laboratorium Mekanika dan Mesin-mesin Fluida, Jurusan Teknik Mesin FTI – ITS, Surabaya. Pompa beserta instrumen perpipaan diperkirakan telah mengalami penurunan performa. Penurunan performa ini diakibatkan usia peralatan yang sudah sangat tua dan minimnya perawatan yang dilakukan terhadap sistem, serta banyaknya bagian-bagian yang telah hilang. Karena itu, pengujian terhadap performa pompa dan head loss sistem perpipaan yang digunakan dalam penelitian ini perlu dilakukan. Sistem perpipaan OGAWA SEIKI cavitation phenomenon experimental equipment telah dimodifikasi dengan sebagian besar sistem perpipaan menggunakan material Polyvinyl Chloride (PVC) berdiameter 2 in. Fitting perpipaan terdiri atas elbow 90o serta reducer. Beberapa pressure tap dihubungkan dengan manometer raksa dengan specific gravity (SG) 13,6. Head loss pipa dianalisis menggunakan formulasi Swamee-Jain dan persamaan Darcy Weisbach. Pengujian pompa melibatkan pengukuran tekanan suction dan tekanan discharge pompa menggunakan pressure gauge pada bagian inlet dan outlet. Pompa dapat beroperasi pada kapasitas maksimal 3,9 L/detik. Variasi bilangan Reynolds pada aliran turbulen dilakukan pada debit 0 L/detik hingga debit maksimal yang mampu dicapai untuk pipa PVC diameter 2 in pada line dengan variasi 0,2 L/detik. Visualisasi kavitasi diamati seiring dengan pengubahan debit aliran pada sistem. Dari eksperimen, diperoleh data berupa grafik perbandingan bilangan Reynolds (Re), koefisien losses (KL), visualisasi kavitasi dan grafik kerja pompa dengan menggunakan beberapa model pengganggu. =================================================================================== OGAWA SEIKI cavitation phenomenon experimental equipment is one of piping system testing equipment with cavitation modeling can be found in the Laboratory of Fluid Mechanics and Turbo-machinery, Department of Mechanical Engineering FTI - ITS, Surabaya. The performance of pump and piping instrument is estimated to have decreased. The decline in performance is due to the age of the equipment is very old and lack of maintenance done on the system, and the many parts that have been lost. Therefore, testing the performance of the pump and piping system head loss used in this research needs to be done. Piping system of OGAWA SEIKI cavitation phenomenon experimental equipment has been modified to most piping systems using material Polyvinyl Chloride (PVC) in diameter 2 in. Fitting piping consists of 90o elbow and reducer. Some pressure tap connected with the mercury manometer with specific gravity (SG) 13.6. Head loss in pipes were analyzed using Swamee-Jain formulations and equations Darcy-Weisbach. Testing involves measuring the pump suction pressure and discharge pressure of the pump using a pressure gauge at the inlet and outlet. The pump can operate at a maximum capacity of 3.9 L / s. Variations Reynolds number in turbulent flow performed on debit 0 L / sec up to a maximum discharge that can be achieved for PVC pipe diameter 2 in the line with a variation of 0.2 L / s. Visualization cavitation was observed along with changing the flow rate of the system. From the experiment, the data obtained in the form of graphs comparing the Reynolds number (Re), losses coefficient (KL), visualization cavitation and pump working charts using several models bully.
