RANCANG BANGUN ALAT UJI HEAD STATIS POMPA PADA TEKANAN TANGKI 2 BAR ( DESIGN OF STATIC HEAD TEST EQUIPMENT TANK PRESSURE PUMP AT 2 BAR )

Abstract

Pembuatan alat uji head statis pompa ini dimaksudkan untuk menerapkan teori-teori yang telah didapatkan selama masa perkuliahan dalam mengetahui head statis pompa, karakteristik pompa dan efisiensi pompa. Pengujian dilakukan dengan cara mengatur bukaan katup serta pengarutan frekuensi untuk mendapatkan data-data yang dibutuhkan dalam mencari head statis, karakteristik, dan efisiensi pompa. Dari hasil pengujian head statis pompa menggunakan fluida air pada tekanan dalam tangki 2 bar diperoleh data sebagai berikut : debit maksimal 11,5 LPM dengan head total 21,30 m dan head sistem 21,70 m dan debit terendah 3 LPM dengan head total 32,31 m dan head sistem 21,59 m. dari hasil pengujian didapat titik kerja pompa pada laju aliran 11,25 LPM dengan head pompa 21,902 m. Kata kunci: pompa, head statis, Karakteristik pompa, head sistem, head total, laju aliran. In operation, the pump must be able to meet the head required by the system piping. Static head pump must be determined by considering the characteristics of the pump when the water level changes. Therefore made final project "Design of Static Head Test Equipment Pump at Pressure of 2 Bar”. The purpose of this tool is to determine the characteristics of the pump system by calculating: total pump head, head system with the method (calculation) and (measurement) and the efficiency of the pump, that is by setting the pump flow rate through the valve opening and frequency setting through an inverter. Test results using the pump static head of fluid in a tank of water at a pressure of 2 bar are as follows: total head of the pump at the highest discharge of 21,30 m and a total head of the pump at the lowest discharge of 32,31 m. While the head system (calculation method) at the highest discharge of 21,70 m and the lowest at 21,59 m discharge and head system (method of measurement) at the highest discharge 21,70 m and the lowest discharge 21,59, the test results pump working point obtained at a flow rate 11,25 LPM (liters Per Minute) with 21,902 m pump head.
