STUDI EKSPERIMENTAL PENGARUH TIPE BANTALAN YANG DIGUNAKAN, PERUBAHAN KAPASITAS DAN HEAD POMPA SENTRIFUGAL SATU TINGKAT TERHADAP PRILAKU VIBRASINYA
ABSTRACT: This paper is a
report of the results of a research on the influence of bearing type due to the
vibration characteristic of a single-stage centrifugal pump. The pump used in
this research is a centrifugal pump with maximum head of nine meters, maximum
capacity of 3.5 liter/second and power of 746 Watt. Poly Vinyl Carbon (PVC)
pipe is used in suction and discharge pipes. The suction pipe of 50 mm in
diameter and 1.73 meters long which are equipped with valve and pipe support.
The discharge pipe of 50 mm in diameter and 4.4 meters long which are equipped
with valve, water meter, manometer and pipe support. The static head of the
system is 1.13 m and the total head of system is three meters. The vibration
characteristic test is observed and analyzed through vibration parameters
consisting of displacement, velocity and acceleration. Vibration measurement is
range from the head three meters to seven meters and the vibration response is
measured by Vibrometer Analog VM-3314A. P-01 and P-02 are the measurement
points on pump and measured in axial, vertical and horizontal direction. Deep
groove ball bearing as the original pump bearing, cylindrical bearing, and
tapered bearing are types of bearing which used in this research. These two
types of bearing are mostly found in field to be applied, when the original
pump bearing are replaced for maintenance or life time reason. The result of
research reveals that the highest displacement in horizontal direction occurred
at P-02 with head of three meters, capacity of 1.3 liter/second when ball
bearing is used in the pump with value of displacement 37.125 m. Tapered bearing produces the lowest displacement compared to ball
bearing or cylindrical bearing with the displacement value of 27.1 m in
the same condition.
