TINJAUAN KARAKTERISTIK GETARAN PADA POMPA SENTRIFUGAL SATU TINGKAT PARALEL

Abstract

A centrifugal pump is one type of pump that is very widely used, especially in the water treatment industry. This study is a review on the vibration characteristics of a centrifugal pump paralel.Pompa level used in this study is a type of centrifugal, maximum capacity of 3.2 liters / sec and 1850 watts of power. Suction pipe and pipe press using PVC pipe, 2.5-inch diameter suction pipe with a length of 0.77 m and is equipped with a valve and manometer. Press 3 inch diameter pipeline with a length of 2.78 m is equipped with a valve. Manometer and flowmeter. The low vibration pump at a point located on the P-02 at a price of 27.5 x 10-6 m deviation axial direction in round n = 1000 rpm, while the highest are in elektromotor at P-03 to the price deviation of 170 x 10 - 6 m in the axial direction of rotation n = 1800 rpm. highest frequency is 46 Hz, with deviation 2.40 x 10-6 m at the point P0-3 axial direction and the vertical rotation n = 1800 rpm, Speed 4.10 x 10 - 2 cm / s at the point P0-4 axial direction in round n = 1200 rpm, Acceleration 2.75 x 10-2 cm/s2 at point P0-3 axial direction in round n = 1800 rpm.
