CAUSES OF GEAR-WHEEL FAILURES IN HYDRAULIC PUMPS
This paper reports a wide spread occurrence of wheel pumps in various spheres of industry which stipulates for the urgency of their study. The most significant is forecasting a pump resource under real conditions. To solve this problem it is necessary that the causes of gear-wheel failure of a pump should be studied first. The knowledge of failure nature and processes causing the failure allow increasing a pump reliability and pump life.
