Introduction Of Hydraulic Pumps & Frequently Encountered Problems
Hydraulic Pumps are used in hydraulic drive systems (They can be hydrostatic or hydrodynamic). These pumps convert mechanical power into hydraulic energy. Hydrostatic pumps are positive displacement pumps whereas hydrodynamic pumps are variable displacement pumps. In our day-to-day life, we frequently use hydrodynamic pumps while hydrostatic pumps generally used in the fluid power motion control applications. There are various types of Hydraulic Pumps. Some of them are Gear pumps , Rotary Vane pumps, Screw pumps, Bent axis pumps, Axis Piston pumps, Radial Piston pumps, Peristaltic pumps. There are a number of reasons which can cause the failure of a Hydraulic Pump. Among them, some notable problems and their solutions are listed below: * It is an estimation by many Hydraulic Pump Manufacturers that 70 to 80 percent of hydraulic system failures are from contaminations. To prevent such damaging effects, we should perform oil analysis with particle counts at regular intervals. *
