Redesign and modification of torque measurement instrument for centrifugal pump

Abstract

Abstract The main function of a pump is moving fluid through a pipe from one place to another. The dominant characteristic of a centrifugal pump is its output torque and power. Torque is obtained from the measurement of force using a dynamometer, then the result is multiplied by the moment measuring arm (L). Dynamometers are used to measure weight, which is influenced by gravity, which is mass (m) multiplied by the acceleration of gravity (g). The design concept of this equipment consists of a free moving motor body, dynamometer layout, safety pump, and fluid flow pipe. The pump is designed to be equipped with laboratory scale test kits and sketches of images made using ZWcad. The product design test is carried out using a comparison of the torque value to the centrifugal pump both in filled and unfilled condition. The difference in the value of the output torque is not too far from the theoretical calculation, so this torque measuring instrument is worth using.
