How do you calculate hydraulic flow rate? Multiply the cross-sectional area by the flow velocity, provided in unit of length over unit time squared. If the cross-sectional area and flow are truly perpendicular, the flow rate angle is zero degrees. The value you just calculated is the hydraul...
Cavitation of the pump can occur which can cause internal damage to pump components, insufficient lubrication, and reduced pumping efficiency. When selecting your hydraulic oil look for the Viscosity Index (VI). This value indicates the effect of temperature on the viscosity. Oils with high VI mai...

06" During the test run and operation, the axial piston pump components must be filled with hydraulic oil and vented. After a long period of downtime, oiling and venting operations are required as the system may drain through the hydraulic lines. 07 Contamination has fatal damage to hydraulic ...
Changing the rotation of a XV unidirectional pump Let’s see together step by step how to change the rotation of a Vivoil XVunidirectional pump, but first some important directions: to change the rotationyou don’t need to replace the front flange, you can use the one you already have ( ...
The invention relates to a method for controlling a start-up of an electric vacuum pump for a vacuum system of a vehicle, wherein the start-up can occur according to at least two different start-up modes, i.e., according to a standard mode and according to at least one special mode,...
See the "Visualizing the Pump Curve" section of each documentation page. The load curve can be generated by using an ideal source (flow or pressure) to drive fluids through the load and record the flow and pressure values. Head and pressure drop can be converted ...
with the volumetric flow Q and hole radius R, which still bears resemblance to the original shear rate formula. You calculate Q by dividing the pressure drop across the channel ΔP by the polymer viscosity η, similar to the original equation for shear st...
Rexroth's hydraulic pump has a small displacement and needs to adjust the variable piston to increase the swash plate angle. The oil discharge in the middle position is not zero, and the inclination angle of the swash plate of the A10VSO variable pump is zero, which is called the middle po...
Priming the Pump In this edition of our Commercial Market Roundtables we sat down with Mark Chaffee, VP Governmental Affairs and C&I Product Management at Taco, Tom Cooper, Sales Engineer at Emerson Swan, and Peter Gaydon, Director of Technical Affairs at Hydraulic Institute....
