Abstract

Turbin air merupakan mesin konversi energi yang mengubah energi potensial air diubah menjadi energi mekanis. Pengkonversian energi yang dilakukan oleh turbin air tersebut dapat dilakukan secara implus yang diwakili turbin air jenis Pelton. Dimana proses impuls yang terjadi pada turbin air Pelton yaitu dengan mengubah seluruh potensi energi air (potensial, kecepatan dan tekanan) yang tersedia diubah menjadi energi kinetik yang memutar tubin untuk menghasilkan energi putar. Guna memaksimalkan dan mengotomatisasi perencanaan turbin air jenis Pelton maka dalam penelitian ini digunakan perangkat lunak TURBNPRO 3. Perangkat lunak TURBNPRO 3 memfasilitasi perancang untuk melakukan berbagai macam pemodelan sehingga didapatkan kondisi maksimal sesuai dengan kondisi di lapangan. Di samping itu dengan menggunakan perangkat lunak ini maka perancang juga bisa langsung mendapatkan dimensi serta grafik jangkauan kerja dari turbin yang dirancang.

Abstract

Ceiling installation auxiliary tool is auxiliary tool for installing a ceiling with a simple method. Namely by placing the ceiling above the cross section and moving the gears to the ceiling can reach the desired height. This auxiliary tool is needed to help to lighten the workload and save the ceiling installation time. This auxiliary tool can reach places or rooms that have narrow access, because this tool can be dismantled pairs. This tool can hold the user load up to 80 kg and the weight of the ceiling up to 47.3 kg, so the total weight reached 127.3 kg. This auxiliary tool has four pedestal wheels that can move as desired.

Abstract

Centrifugal pump is one of the most important components that is widely used by industry and functions to move liquids in the form of water or other liquid. One of the things that often happens on centrifugal pumps is the occurrence of high vibrations and abnormal sounds. High vibration in the pump is something that should be anticipated because it can cause damage to the bearings, seals, and shafts. If the pump continues to operate in this condition, it will also cause damage to other pump components and cause the pump to stop operating. Therefore, the condition of the pump must be monitored regularly to ensure that the pump can operate properly. One of the most frequently used methods to find out where high vibrations come from is to use the aptitude analyst application that will produce a unique vibrational spectrum. Vibration analysis is done by observing the amplitude and frequency of the vibration signal. Vibration spectrum analysis can detect pump damage without having to disassemble the equipment and can provide early warning before major damage occurs and takes a large repair cost. The results showed that the existence of high vibration at the 11-PA-7131A pump was caused by the parallel misalignment that occurred at the pump shaft and motor. This is indicated by the high amplitude of vibration on orders 1x, 2x and followed by the presence of amplitude on orders 3x. Vibration data retrieval after the alignment process on the pump shaft and motor also proves that there is a very significant change in vibration amplitude on orders 1x, 2x, and on order 3x. Overall vibration also experienced a very significant decrease so that the pump can be operated normally.
