This study focuses on the effect of surface coating on the impellers and diffusers in improving the efficiency of mixed flow submersible borewell pumps. It consists of two parts. In the first part, a 3 stage pump was constructed with uncoated bronze impellers and cast iron diffusers having a surface roughness value of 2.5μm Ra and tested for pump performance. Then the same 3 stage pump was test...

Penelitian ini bertujuan untuk membuat inovasi alat pengambil sampel air berdasarkan kedalaman yang berbeda dengan menggunakan pompa submersible pump. Submersible pump digunakan adalah Diesel Pump Operation Instruction DC 24V kapasitas 12 L/menit, cara kerja yaitu, mengisap di dasar perairan dan mendorong ke atas, sehingga hasilnya bisa ditampung. Pompa dipasang dalam pipa PVC 11/4inc kemudian ...

In order to study the influence of position bulb on hydraulic performance a submersible tubular pump device, based large-scale pumping station, two schemes—involving front-mounted and rear-mounted bulb, respectively—were designed. The scheme uses GL-2008-03 model its conventional guide vane, while optimized design diffuser vane. method combining numerical simulation experimental testing was use...

Solar DC pump system is easy to install and operates full automatically without watching. Solar DC pump needs less solar panels to run than the AC pump. A simulation model is necessary for the manufacturer to assess the performance of solar pump controller. Solar DC Pump consists of solar PV Modules, solar DC controller, and submersible DC pump. Solar cells have nonlinear I-V characteristics, e...

The shaft is a critical component in ESP. In many cases, dismantle analyses cannot identify definitive root cause for failure. Several hypotheses have been studied to explain This paper will review typical failure modes; more specifically, the power source and consequence of be discussed. An analysis premature used an electrical submersible pump (ESP) lifting oil has carried out. During root-ca...

Abstract A supply and demand balance control method for an electrical submersible linear motor utilised in offshore oil exploitation is proposed this study. The permanent magnet replaced by based on switched reluctance motor. sensorless further enhances the stability of system. Meanwhile, a to maintain fullness plunger pump within ideal range. An established speed function allows dynamically al...

The electric submersible pump (ESP) is a centrifugal with several stages. It's dependable and efficient industrial lifting tool for different amounts of fluids, it's known its adaptability reliability. Electric pumps are commonly used in onshore oil wells, as well underground pumping other applications. pump's efficiency evaluated under the control various rotational speeds. CFD approach this a...
