This thesis is concerned with the experimental study of the vibration of the low head centrifugal pumps used for irrigation to declare the effect of : 1.rate of flow. 2.operation head-suotion head. 3.material of suction pipes. The effect of the pumped water temperature on the vibration level of a small model centrifugal pump is also included. The results of the experimental investigation showed that the widely spread flexible hose, which is usually used with the centrifugal pumps used for irrigation, for its flexibility, is not a good solution from vibration point of view. Surface irregularity of the flexible hose rises the level of vibration than that in case of the steel piping. The results of the experimental investigation showed that the widely spread flexible hose, which is usually used with the centrifugal pumps used for irrigation, for its flexibility, is not a good solution from vibration point of view. Surface irregularity of the flexible hose rises the level of vibration than that in case of the steel piping. The results showed also that the level of vibration of the plastic suction pipes is higher than that for the flexible hose. It was shown also that the non-return valve, with the ordinary design is the powerful source of vibration in the pumping system. This may lead to conclusion that a new design of foot valves, with a better vibrational performance is very necessary./a)It is well known that the vibration of mechanical parts of any machin have a harmfull effects, which may cause failer of the machine elements.
