Abstract

This research concerned the standard value of surface roughness on Computer Numerical Control (CNC) to obtain fine pipe cutting result and is more useful for company to simply recognize the appropriate standard gap in designing. Standard design used is 30 mm with 3 specimen variations and variation gap value of 42 mm, 44 mm, and 46 mm. In recognizing fine refinement, standard on Roughness Average (RA) is used with surface roughness scale tool. Based on the experiment, it shows that gap design for pipe with Computer Numeric Control (CNC) in 30 mm has less optimum result because its cutting result still has crust, the gap is still considered too close. Therefore, re-grinding was conducted to result smoother result in achieving surface roughness value of 32RA. Fine pipe result without crust is 46 mm with roughness value of 4 RA. The smaller value obtained from measuring surface roughness, the more optimum result obtained.

Abstract

Mesin pencoak pipa (pipe notcher) yang ada di pasaran saat ini harganya cukup mahal sehingga banyak bengkel-bengkel kecil masih menggunakan cara konvensional untuk melakukan pencoakan pipa. Cara yang biasa digunakan adalah dengan menggunakan gerinda tangan, sehingga membutuhkan waktu yang lama dan hasilnya kurang presisi. Untuk itu pada penelitian ini dirancang mesin pencoak pipa dengan memanfaatkan sabuk amplas sebagai V-belt yang dihubungkan dengan poros dan digerakkan oleh motor listrik. Kemudian benda kerja didekatkan pada poros matras dan selanjutnya ditekan maju sampai terbentuk profil yang diinginkan. Rancang bangun mesin pencoak pipa multi dimensi ini terbagi dalam tiga tahap. Tahap pertama konsep desain dan perencanaan komponen, dilanjutkan dengan tahap pembuatan dan terakhir adalah pengujian mesin. Dari hasil rancang bangun diperoleh bahwa mesin pencoak pipa multi dimensi ini menggunakan motor listrik 0,5 HP dan putaran 1400 rpm sedangkan rangka mesin menggunakan besi siku ukuran 4 x 4 cm. Setelah dilakukan pengujian, mesin dapat bekerja dengan baik. Untuk mencoak pipa dengan diameter 3/4 inch dibutuhkan waktu selama 0,335 menit, sedangkan untuk pipa ukuran 1 inch membutuhkan waktu selama 1,075 menit. Sedangkan profil yang dibuat menggunakan mesin ini mampu membentuk sudut antara 0° sampai dengan 30°. Pipe notcher on the market today are quite expensive so that many small workshops still use the conventional method for cutting special pipe profiles. The method commonly used is to use hand grinding, so it takes a long time and the results are less precise. For this reason, in this study was designed a pipe notcher machine using the sandpaper belt as a V-belt connected to a shaft and driven by an electric motor. Then the workpiece is brought closer to the mattress axis and then pressed forward until the desired profile is formed. The design of this multidimensional pipe notcher engine is divided into three stages. The first stage is the design concept and component planning, followed by the manufacturing stage and the last stage is machine testing. From the design results, it is found that this multi-dimensional pipe notcher machine uses an electric motor 0.5 HP and a rotation of 1400 rpm while the engine frame uses 4 x 4 cm angle iron. After testing the machine can work properly. To check a 3/4 inch pipe it takes 0.335 minutes, while for a 1 inch pipe it takes 1.075 minutes. Meanwhile, the profiles made using this machine are capable of forming angles between 0 ° to 30 °.

Abstract

This study aims to determine the effect of fluid velocity and the distance between the zig zag filter on the cooling tower by varying the distance between the zig zag bio filter foam. In this study, bio filter foam material was used in a zig zg shape using wire mesh where the distances tested were 5cm, 10cm, and 15cm. Then the water is heated using a heater until it reaches a temperature of 40ºC and then the water is flowed up by a pipe using a pump and removed using a nozzle, then the hot water will go down to the reservoir by passing the bio filter foam arrangement that has been installed with a distance of 5cm , 10cm, and 15cm. Where there is also a drain valve that is done, namely a closed faucet and also an open kran and fully open faucet. A good cooling value is shown at a distance of 5 cm where the average temperature difference is 3.47 C and the effectiveness is 26.67%.

Abstract

The purpose of this study was to determine the characteristics of the two centrifugal pumps using the same circuit and to obtain the resulting value, namely head, discharge, pump power, efficiency of the two pumps. And variations in valve opening settings used are full valve openings, valve openings 2/3, and valve openings 1/3 which have different coefficients at each valve opening. This research method was carried out experimentally. The fluid used is water, fluid pressure measurement using a pressure gauge to measure the pressure side (discharge) and a vacuum pressure gauge to measure the pressure which is relatively lower than the atmospheric pressure for the pump on the suction side (suction) and using a flow meter to determine the volume or discharge water used. The results of this centrifugal pump test equipment research found that the working pump shows that the resulting discharge affects the head value, pump power, and pump efficiency obtained, the higher the total head value, the smaller the resulting discharge. However, this centrifugal pump test equipment can be used for fluid practicum activities in the mechanical engineering department in the mechanical laboratory.

Abstract

The bearing puller on the market today still has a way of working using a gripper with a screw working system. The time required is relatively long and can allow damage to the crankshaft during the bearing release process as well as reduced work performance of the crankshaft. This study aims to design a tool that works with a hydraulic system to release crankshaft motorbike bearings. This tool makes it easy for everyone to do the job of removing bearings. The outer bearing hydraulic tracker or puller uses the working principle of the lever that is pumped with calculated pressure and load and the fluid pressure on the tracker can be known ie at 1X the tracker pump requires 41 kg / cm2 fluid pressure, 2X fluid pressure tracker pump 45 kg / cm2 and 3X pump tracker requires 72 kg / cm2 fluid pressure. As well as the time needed to remove the crankshaft bearing motor especially on the A and B motorbike. To release the crankshaft bearing A motor takes 19.78 s and removing the crankshaft bearing the B motor takes 31.95 s.
