Abstract

Modifikasi alat uji test bed pompa sentrifugal ini dimaksudkan untuk menerapkan teori-teori yang telah didapatkan selama masa perkuliahan dalam mengetahui head statis pompa, head total pompa, daya hidrolis pompa, daya input motor pompa dan efisiensi pompa, serta NPSH pada pompa. Pengujian dilakukan dengan cara mengatur bukaan katup dan mengatur putaran impeler dengan cara memvariasi frequensi untuk mendapatkan data-data yang dibutuhkan dalam mencari head sistem, head total, daya hidrolis, daya input motor dan efisiensi, serta NPSH pada pompa. Dari hasil pengujian test bed pompa menggunakan fluida air pada tekanan tangki 1 = - 0,6 bar dan tekanan tangki 2 = 1,15 kgf/ dengan variasi bukaan katup diperoleh data sebagai berikut : debit maksimal 25 LPM dengan head sistem 6,5 m, head total 17,6 m, efisiensi 32,73% dan NPSH 5,36 m. Pada variasi putaran impeler diperoleh data sebagai berikut : debit maksimal 25 LPM dengan head sistem 6,5 m, head total 18,11 m, efisiensi 30,05% dan NPSH 5,36 m. Kata kunci = pompa, head statis, karakteristik pompa, head sistem, head total, laju aliran. Modifications of centrifugal pump test bed is intended to apply the theories that have been obtained during the lecture in knowing the static head pump, pump total head, pump hydraulic power, pump motor input power and pump efficiency, and NPSH. Testing is done by adjust the valve and adjust the impeller rotation with varying the frequencies to obtain data required in the search for system head, total head, pump hydraulic power, pump motor input power, efficiency and NPSH. From the test results test bed using a fluid pump water at a pressure tank 1 = - 0,6 bar and the pressure tank 2 = 1,15 kgf / cm2 with a variation of the valve opening is obtained the following data: a maximum discharge head 25 LPM with the head system 6, 5 m,total head 17,6 m, efficiency of 32,73% and NPSH 5,36 m. In a variation of impeller rotation is obtained the following data: a maximum discharge head 25 LPM with the head system 6,5 m, total head 18,11 m, efficiency of 30,05% and NPSH 5,36 m. Keywords = pump, static head, pump characteristics, head of the system, the total head, flow rate.
