Abstract
Wearing means the abrasion of machinery or other materials because of a lot of use and over time. Wearing can be examined under 4 different groups. These are mechanical wear, corrosion, cavitation and fatigue. Mechanical abrasion is the mechanical removal of metal by cutting or the abrasion of suspended solid particles carried in the liquid, which is a loss of material. Corrosion is the change in the physical, chemical and mechanical properties of materials as a result of the chemical and electrochemical effects of the environment they are in. Cavitation is the result of the formation of vapor bubbles in the liquid subjected to intense local pressure changes and the detonation resulting from the explosion in the high pressure zone. Wearing which occurs in machine elements under variable stresses is called fatigue. Centrifugal pumps are from the dynamic pump group and are the most widely used pump type in agricultural irrigation. They work in very difficult and critical environments. They encounter many wear-out problems throughout their lifetime. In this study, the types of wearing observed in centrifugal pumps were investigated and the effects on the centrifugal pumps were investigated.
Highlights
Centrifugal pumps are used for transferring water from ground and ground water sources to other places
Centrifugal pumps enter the dynamic pump group used for irrigation (Fig. 1)
As the flow rate of centrifugal pumps increases, the pressure remains to a certain extent
Summary
Centrifugal pumps are used for transferring water from ground and ground water sources to other places. Centrifugal pumps enter the dynamic pump group used for irrigation (Fig. 1) They continuously give energy to the fluid. The relationship between the flow rate and the speed is not linear. There is an inverse relationship between flow rate and head Centrifugal pumps take up less space, are light and cheap Their efficiency is low at low flow rates and high pressures (Keskin and Güner, 2012). In centrifugal pumps; there are impeller, pump shaft, casing, chasis, suction and discharge port, diffuser, sealing elements (stuffing box), impeller and wearing rings connected to the body. The wearing rings are located on the impeller, on the body or on both the impeller and the body These rings prevent fluid from passing through the discharge line into the suction line. Stuffing box prevents leakage between air and liquid leaks between shaft and body (Keskin and Güner, 2012)
