Abstract

Peningkatan kebutuhan energi di dunia dipicu oleh laju pertumbuhan penduduk dan GDP. Perusahaan penghasil energi listrik membutuhkan inovasi untuk meningkatkan kapasitas energi yang dihasilkan, salah satunya dengan menggunakan rangkaian seri dan paralel pada pompa. Pompa digunakan untuk memindahkan fluida dari suatu tempat ke tempat lain dengan menimbulkan perbedaan tekanan pada bagian inlet dan outlet. Penelitian telah dilakukan untuk meningkatkan kapasitas dan tekanan pompa dengan rangkaian tunggal, seri, dan paralel. Eksperimen yang dilakukan merupakan evaluasi performa pompa single, rangkaian seri dan rangkaian paralel. Penelitian ini menggunakan dua pompa yang diasumsikan identik dengan menggunakan operasi individual, rangkaian seri dan paralel lalu dihubungkan pada CUSSONS friction loss in pipe apparatus yang merupakan fasilitas yang digunakan pada departemen Teknik Mesin FT-IRS ITS sebagai media untuk menguji head loss pada sistem perpipaan. Kemudian terdapat alat – alat yang diperlukan antara lain: pompa yang digunakan pada penelitian ini merupakan pompa 1 dan pompa 2 dengan daya masing – masing 750-watt (1 HP) dengan spesifikasi Kapasitas maksimal sebesar 120 L/m, Head maksimal sebesar 32 m, dan Head minimum sebesar 14 m. Kemudian CUSSONS friction loss in pipe apparatus merupakan sebuah sistem perpipaan yang terdapat pada Laboratorium Mekanika dan Mesin – Mesin Fluida. Selanjutnya Water calculating unit, ball valve pressure taps, dan Inverter DC 1 fasa input – output. Pada penelitian ini melibatkan pengukuran pada tekanan suction (Ps) dan discharge (Pd) pompa, tegangan (V) dan arus listrik (A) yang dibutuhkan oleh pompa, losses yang terjadi pada sistem perpipaan (Hpl) dan kapasitas aliran (Q). Parameter tersebut diukur dengan variasi rangkaian dari pemasangan pompa yang digunakan. Pengukuran parameter tersebut menggunakan alat ukur pressure gauge, clamp meter, manometer U dengan fluida ukur air raksa dan rotameter. Berdasarkan penelitian yang telah dilakukan dapat diasumsikan bahwa pompa CPM 158-1 dengan pompa CPM 158-2 dapat diasumsikan sebagai pompa yang identik. Hal ini dapat dibuktikan melalui head dan kapasitas yang dihasilkan oleh kedua pompa. Dimana data yang dihasilkan mendapatkan Error pada putaran kecepatan 1500 rpm antara pompa 1 dengan pompa 2 adalah sebesar 2.8% hingga 5.2%. selanjutnya melalui data di putaran kecepatan 3000 rpm didapatkan antara pompa 1 dengan pompa 2 adalah sebesar 3.5% hingga 5.5%. Dengan nilai error sebesar ini dapat diasumsikan bahwa pompa 1 dan pompa 2 merupakan pompa yang identic. Penggunaan pompa dengan rangkaian seri meningkatkan head secara signifikan. Pada putaran 1500 rpm, pompa seri memiliki head 14.33 m, sedangkan pompa tunggal hanya memiliki 9.32 m. Pada penelitian yang telah dilakukan didapatkan peningkatan head sebesar 1.3 hingga 1.5 kali lipat untuk putaran 1500 rpm. Pada putaran kecepatan impeller 3000 rpm, pompa seri memiliki head 61.36 m, sementara pompa tunggal hanya 32.31 m. Terjadi peningkatan head sebesar 1.8 hingga 1.92 kali lipat pada kedua putaran tersebut. Selanjutnya Penggunaan pompa dengan rangkaian paralel meningkatkan kapasitas secara signifikan. Pada putaran 1500 rpm, pompa paralel memiliki kapasitas 48 L⁄min dan head 7.52 m, sedangkan pompa tunggal hanya memiliki kapasitas 38 L⁄min dan head 6.98 m. Pada putaran 3000 rpm, pompa paralel memiliki kapasitas maksimal 70 L⁄min dengan head 24.34 m, sedangkan pompa tunggal hanya memiliki kapasitas maksimal 96 L⁄min dengan head 24.13 m. Terjadi peningkatan kapasitas sebesar 1.4 kali lipat pada putaran 1500 rpm dan 1.37 kali lipat pada putaran 3000 rpm pada pompa dengan rangkaian paralel dibandingkan dengan pompa tunggal.

The increase in energy demand in the world is triggered by the rate of population growth and GDP. Electrical energy producing companies need innovation to increase the capacity of the energy produced, one of which is by using series and parallel circuits for pumps. Pumps are used to move fluids from one place to another by creating a pressure difference at the inlet and outlet. Research has been carried out to increase the capacity and pressure of pumps with single, series and parallel circuits. The experiments carried out are the evaluation of the performance of single pumps, series circuits and parallel circuits. This study uses two pumps which are assumed to be identical using individual operations, series and parallel circuits and then connected to the CUSSONS friction loss in pipe apparatus which is a facility used in the FT-IRS ITS Mechanical Engineering department as a medium for testing head loss in piping systems. Then there are the tools needed, including: the pumps used in this study are pump 1 and pump 2 with a power of 750-watt (1 HP) each with a maximum capacity specification of 120 L/m, a maximum head of 32 m, and a minimum head of 14 m. Then CUSSONS friction loss in pipe apparatus is a piping system found in the Fluid Mechanics and Machinery Laboratory. Furthermore Water calculating unit, ball valve pressure taps, and DC Inverter 1 phase input – output. This study involves measuring the suction pressure (Ps) and discharge (Pd) of the pump, voltage (V) and electric current (A) required by the pump, losses that occur in the piping system (Hpl) and flow capacity (Q). These parameters are measured by the series variations of the pump installation used. Measurement of these parameters using a pressure gauge, clamp meter, U manometer with mercury measuring fluid and rotameter. Based on the conducted research, it can be assumed that pump CPM 158-1 and pump CPM 158-2 can be considered as identical pumps. This can be supported by the similarity in head and capacity produced by both pumps. The data obtained at a speed of 1500 rpm and minimum capacity (0 L/min) showed that pump CPM 158-1 had a head of 9.32 m and 0% efficiency, while pump CPM 158-2 had a head of 9.06 m and 0% efficiency. Similarly, at the maximum capacity of 38 L/min, both pumps had the same head values, with pump CPM 158-1 at 6.98 m and 25.36% efficiency, and pump CPM 158-2 at 6.61 m and 24.40% efficiency. The error between pump 1 and pump 2 at 1500 rpm was found to be in the range of 2.8% to 5.2%. Further analysis at a speed of 3000 rpm and minimum capacity showed that pump CPM 158-1 had a head of 32.31 m and 0% efficiency, while pump CPM 158-2 had a head of 31.17 m and 0% efficiency. At the maximum capacity of 70 L/min, both pumps had the same head values, with pump CPM ix 158-1 at 24.13 m and 38.11% efficiency, and pump CPM 158-2 at 22.81 m and 36.21% efficiency. The error between pump 1 and pump 2 at 3000 rpm was found to be in the range of 3.5% to 5.5%. Furthermore, the research findings indicate that using pumps in series configuration significantly increases the head generated by the pumps. At 1500 rpm, the series configuration pump had a head of 14.33 m, while the single pump had a head of 9.32 m at the same capacity. The research showed a head increase of 1.3 to 1.5 times in the series configuration. At a speed of 3000 rpm, the series configuration pump had a head of 61.36 m, whereas the single pump had a head of 32.31 m. A head increase of 1.8 to 1.92 times was observed at both speeds. Additionally, using pumps in parallel configuration significantly increases the capacity. At 1500 rpm, the parallel configuration pump had a capacity of 48 L/min and a head of 7.52 m, while the single pump had a capacity of 38 L/min and a head of 6.98 m. At 3000 rpm, the parallel configuration pump had a maximum capacity of 70 L/min with a head of 24.34 m, while the single pump had a maximum capacity of 96 L/min with a head of 24.13 m. There was a capacity increase of 1.4 times at 1500 rpm and 1.37 times at 3000 rpm in the parallel configuration compared to the single pump configuration.
