PENGARUH VARIASI DEBIT ALIRAN DAN PIPA ISAP (SECTION) TERHADAP KARAKTERISTIK POMPA SENTRIFUGAL YANG DIOPERASIKAN SECARA PARALEL

Abstract

The pump is a machine used to raise the liquid from the surface of the low to the higher, or move the fluid
from the high pressure. Plan and create a means of centrifugal pumps for water flow to the arrangement / circuit
Parallel to the needs of fluid mechanics lab in August 17, 1945 the University of Surabaya. Step experiment with a
gate valve openings 900, 700, 500, 350, with a maximum rotation 2580 RPM pump, get the planning and
characteristics (Head, Capacity) of the two pumps are arranged in parallel. The influence of the suction pipe
diameter variations on these tests affect the capacity (Q). The larger the diameter of the suction pipe is used, the
greater the capacity of the water produced. The influence of variations in flow through the valve opening effect on
Head (H). the smaller the aperture setting, the valve resulting Head Small increasingly.

Keywords: Centrifugal Pumps, Suction Pipe, Valves, Head and capacity.
