RANCANG BANGUN ALAT SIMULASI POMPA HUBUNGAN SERI DAN PARALEL ( ENGINEERING SIMULATION TOOLS OF SERIES AND PARALLEL CONNECTION PUMP )

Abstract

Rancang bangun alat simulasi pompa hubungan seri dan paralel bertujuan untuk mengetahui kinerja pompa. Dari hasil Pengujian karakteristik pompa menggunakan fluida air pada hubungan seri dengan spesifikasi berbeda dapat diperoleh data sebagai berikut : debit maksimal 55 L/min, head total 2,103058 m dan debit terendah 15 L/min dengan head total 36,35731 m, serta menghasilkan efisiensi terbesar 13,9097% pada debit 35 L/min. Sedangkan hubungan paralel dengan spesifikasi berbeda dapat diperoleh data sebagai berikut : debit maksimal 75 L/min, head total 10,40469 m dan debit terendah 15 L/min dengan head total 21,07003 m serta menghasilkan efisiensi terbesar 13,14375% pada debit 60 L/min. Dari hasil simulasi disimpulkan bahwa debit terbesar diperoleh saat hubungan paralel dan head total yang terbesar diperoleh hubungan seri . Kata kunci : Pompa Sentrifugal, kurva karakteristik hubungan seri dan paralel. Engineering simulation tools of series and parallel connection pump aims to determine the performance of the pump system. From result of test of pump charactheristic use water fluid at series connection with specification different can be obtained by following data: maximal debit 55 L/minute, totally head is 2,103058 m and lowest debit is 15 L/minute with totally head 36,35731 m and produces the greatest efficiency 13,9097% with debit 35 L/minute. Whereas parallel connection with specification different can be obtained by the following data : maximal debit is 75 L/ minute, totally head is 10,40469 m and lowest debit is 15 L/ minute with totally head 21,07003 m and produces the greatest efficiency 13,14375% with debit 60 L/minute. From the simulation results concluded that the largest discharge is obtained when a parallel connection and the largest total head obtained connection series. Keywords : Centrifugal Pump , characteristic curve series and parallel connections.
